Description

Ratchet for implant surgery with multiple hinges

The present invention relates to a ratchet for implantation including multiple hinges, and more particularly, to reinforce the maneuverability and mobility of a handle, that is, a handle, compared to a ratchet in which one hinge is installed, so that the fixture can be more conveniently placed in the alveolar bone. It relates to a hinged ratchet for implant treatment.

When placing an implant due to missing teeth, there is a method of inserting a fixture after forming a hole in the alveolar bone to insert the fixture and then inserting the fixture into the hole after inserting a screwdriver that turns the fixture into the handpiece. Another way is to screw a screwdriver into the ratchet without using it and then insert the fixture.

In particular, the latter method is commonly used when it is difficult to turn the fixture with a handpiece.

In the case of using the ratchet described above, if there are no adjacent teeth, the fixture can be inserted to the desired depth without any problems. However, if the length of the driver fastened to the ratchet is short and there are adjacent teeth, if the fixture is inserted to a certain depth in the hole, the adjacent teeth The ratchet gets stuck and you have to replace it with a longer screwdriver before you can drive the fixture to the desired depth.

In this case, it often occurs when the length of the driver is relatively short compared to the height of the adjacent teeth, so there is a solution to replacing the driver with a long driver, but the replacement operation is cumbersome.

In order to solve this problem, US Patent No. 07104165 discloses a wrench for an implant having a handle that is rotated in a swing manner by a joint, that is, a hinge.

According to this technology, it is possible to provide convenience in that it is possible to secure the mobility and convenience of operation for placing the fixture while avoiding interference with adjacent teeth without replacing the driver by lifting the handle portion based on the hinge.

However, when one hinge is provided as in the above technique, the handle must be lifted more than necessary when the length of the driver is relatively short. Problems may follow.

Therefore, by providing a multi-joint, that is, a double hinge so that the handle cannot be lifted more than necessary, the manipulability and mobility of the handle are reinforced without replacing the driver, so that the fixture can be more conveniently placed in the alveolar bone. New and advanced implant procedure This is the reality of the need to develop a dragon ratchet.

The present invention has been made to overcome the problems of the above technology, by providing a ratchet body capable of complex rotation by a double hinge structure to enhance the maneuverability and mobility of the handle, thereby enabling the fixture to be more conveniently placed in the alveolar bone Its main purpose is to provide a ratchet for implant treatment.

Another object of the present invention is to provide a first stopper on the side of the first hinge to prevent a problem in which the tip of the hinge part is lowered more than necessary by the first hinge.

Another object of the present invention is to prevent the problem that the rear end of the hinge part is raised more than necessary by the second hinge or the operating force is not smoothly transmitted to the first hinge and the rear end of the hinge part is rotated first. to provide a stopper.

A further object of the present invention is to ensure a natural and smooth rotation of the first and second hinges by differentiating the rotational properties of the first and second hinges.

In order to achieve the above object, the ratchet for implant surgery including a multi-hinge according to the present invention, the head through which the fastening hole passes; a body extending from an end of the head and including first and second bars connected to a hinge part; It is characterized in that it includes; a hinge portion including first and second hinges, which are rotatably connected at the rear end of the first bar and the front end of the second bar in the through direction of the tightening hole as a rotation path, respectively.

In addition, at the end of the bottom side around the first hinge in the first bar, the bottom of the hinge portion extends so that the first hinge does not rotate downward of the virtual horizontal line based on a virtual horizontal line along the arrangement direction of the teeth It is characterized in that a first stopper protruding and extending along the direction is formed.

In addition, at the end of the upper surface side of the second hinge around the second bar, the upper surface of the hinge portion extends so that the second hinge does not rotate upward of the virtual horizontal line based on a virtual horizontal line along the arrangement direction of the teeth It is characterized in that a second stopper protruding and extending along the direction is formed.

According to the ratchet for implant surgery including multiple hinges according to the present invention,

1) Compared to a single hinge, it guarantees smooth operation and mobility of the body and handle, so it is more convenient to place the fixture in the alveolar bone,

2) By limiting the unnecessary rotation range of the first and second hinges by the first and second stoppers as well as the first stopper, more normal and natural control of the handle is provided,

3) By making a difference in the pivotability of the first and second hinges, it is possible to prevent problems in which the operating force is not properly transmitted to the first hinge or the second hinge rotates first,

4) Adding a functional composition to the second packing that controls the rotation of the second hinge has an effect of enhancing durability such as elasticity.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing indicate like elements.

Figure 1 is a perspective view showing a schematic appearance of the ratchet of the present invention, Figure 2 is a plan view of Figure 1.

1 and 2, the ratchet of the present invention is based on taking a structure in which the head 10 and the body 20 are connected via the hinge portion 100.

First, in the present invention, 'ratchet' is defined as meaning a known implant wrench (torque wrench). That is, in general, the ratchet is used to refer to a wheel or a wheel that rotates in only one direction, but in the present invention, it can be understood that it is used in the same sense as a wrench for implantation.

The ratchet of the present invention has a structure extending in the longitudinal direction. The direction is defined as 'front end direction', and the direction toward the end of the body 20 is defined as 'rear end direction'.

The head 10 may be divided into a front end where the fastening hole 11 is formed and a rear end extending a certain length to be connected to the hinge part 100 at the rear end of the front end, where the head 10 The rear end portion is referred to as a first bar 21 of the body 20 to be described later.

The front end of the head 10 includes a fastening hole 11 having a size corresponding to the standardized head of the fixture.

The tightening hole 11 is a portion penetrated in the vertical direction from the head 10, that is, in the direction perpendicular to the extension direction of the ratchet of the present invention, and the flat shape is circular (for circular drivers), square ( It can be made in various shapes, such as for a square driver).

Rather than having a smooth surface, the inner circumferential surface of the tightening hole 11 is coupled with a plurality of concave-convex O-rings along the inner circumference of the tightening hole 11, or irregularities are formed on the inner circumferential surface of the tightening hole 110 itself. Through this, it is possible to provide a close coupling relationship with the head of the fixture Since the structure of the head 10 is the same as that of a known head, a detailed description thereof will be omitted.

The body 20 has a bar-shaped structure extending a certain length, and the front end and the rear end are connected via a hinge part 100 to be described later in a state in which the front end is connected to the head 10.

The front end of the body 20 is defined as the first bar 21, and the rear end is defined as the second bar 22.

The first bar 21 may refer to a portion extending a certain length from the head 10 towards the hinge portion, or a rear end portion of the head 10 having a circular flat shape, as can be seen from FIGS. 1 and 2 .

That is, the first bar 21 refers to a part extending from the rear end of the head 10 or a part of the rear end of the head 10, and in this case, the first bar 21 and the head 10 The combination of ) forms a circular shape with the tightening hole 11 as the center.

In other words, the first bar 21 may be a rear end extension of the head 10 or a rear end of the head 10 itself without such an extension as shown in the drawing.

The second bar 22 includes a handle so that a user, ie, a medical practitioner, can hold it and operate the ratchet of the present invention.

A known configuration capable of adjusting the high and low of torque may be mounted on the body 20 .

The hinge part 100 has a structure extending a certain length to connect the first and second bars 21 and 22 of the body 20, specifically, the rear end of the first bar 21 and the front end of the second bar 22 In the taken state, the first hinge 110 is mounted at the front end and the second hinge 120 is mounted at the rear end.

That is, the hinge part 100 has a cylindrical shape similar to that of the body 20 or a shape similar thereto, and in the present invention, the surface of the hinge part 100 toward the fixture is referred to as the 'bottom surface' and the surface opposite to the bottom surface as the 'upper surface' ' is defined as

Through the first and second hinges 110 and 120, the hinge part 100 is rotated at the coupling part of the first and second bars 21 and 22, so that the medical worker can operate the ratchet of the present invention more freely. Of course, it provides the convenience of the angle holding the body.

More specifically, the first and second hinges 110 and 120 are first and second hinge holes 111 and 121 penetrating in a direction perpendicular to the through direction of the fastening hole 11 at the front and rear ends of the hinge part 100, respectively, and It may be formed of first and second hinge pins 112 and 122 coupled to the first and second hinge holes 111 and 121, respectively.

Correspondingly, a hole to which the first and second hinge pins 112 and 122 are coupled is formed at a portion corresponding to the first and second hinge holes 111 and 121 at the coupling portion of the first and second bars 21 and 22 .

That is, the first hinge 110 includes a first hinge hole 111 penetrating from the front end of the hinge part 100 along both side directions perpendicular to the extension direction of the hinge part 100 and the first hinge hole 111 ) and a first hinge pin 112 rotatably coupled to the hole of the first bar 21, and the second hinge 120 similarly rotates the hinge part 100 at the rear end of the hinge part 100. The second hinge hole 121 penetrating along both side directions perpendicular to the extension direction and the second hinge pin 122 rotatably coupled to the hole of the second hinge hole 121 and the second bar 22 Consists of

Based on this structure, the functions and actions of the ratchet of the present invention are described as follows.

3 is a cross-sectional view illustrating a rotational state of first and second hinges in the ratchet of the present invention.

As described above, the ratchet including the double hinge, that is, the first and second hinges 110 and 120 serving as two joints, guarantees a range of motion for lifting the second bar 22, so that the driver avoids interference with the teeth. It provides convenience such as conveniently placing the fixture more deeply into the alveolar bone without replacement. As in the prior art mentioned in the background art, if only one hinge is installed at the part connecting the head and body in the ratchet, even if the second bar is lifted (In other words, lifting operation of the second bar) If the length of the driver is too short, the inconvenience of having to lift the second bar additionally and with difficulty follows, and the second bar 22 lifted in this way may be hindered by the teeth (opposite teeth). A possible probability follows.

According to the ratchet including the double hinge, that is, the first and second hinges 110 and 120, as in the present invention, the second bar ( The mobility of 22) is additionally secured, so that the fixture can be placed more conveniently without the hassle of replacing a driver or interference with adjacent teeth.

More specifically, as can be seen from FIGS. 3 (a) and 3 (b), the first hinge 110 is the hinge portion 100 so that the ratchet of the present invention maintains a single shape as much as possible in relation to the fixture. As it guarantees the movement of a predetermined angle (for example, 90 degrees), it provides a role of ensuring the mobility of rotating the driver by lifting the ratchet appropriately to the extent that the adjacent teeth do not interfere.

In other words, the first hinge 110 may provide a function of slightly lifting the second bar 22 when the second bar 22 perpendicular to the driver is caught on the adjacent tooth to avoid interference with the adjacent tooth. .

At this time, as shown in FIG. 3(c), when the second bar 22 rises to the extent that the hinge part 100 and the second bar 22 reach a vertical state, the space in which the second bar 22 is located in the narrow oral cavity Since this is not secured, the second bar 22 cannot sufficiently rise in the posterior teeth due to the structure in the oral cavity.

Moreover, if the second bar 22 is lifted at an angle close to 90 degrees based on the imaginary horizontal line, even if the adjacent teeth can be avoided, the antagonist teeth will interfere.

That is, when the second bar 22 is moved at a small rotation angle to avoid obstruction of the opposing teeth, this problem can be solved by rotation of the first hinge 110, but otherwise, the second hinge 120 further address this issue.

Specifically, the first hinge 110 starts to rotate upward while moving in the direction of the head 10 as shown in FIG. As shown in FIG. 3 (b), when the hinge part 100 is parallel to the driver by rotating to a direction close to 90 degrees based on the imaginary horizontal line, the rotation of the second hinge 22 is shown in FIG. 3 (c) and Similarly, while lowering the height of the hinge unit 100, the first hinge 110 may additionally rotate in the direction of the head 10 or provide a foundation capable of rotating in the opposite direction of the head 10.

In this case, it is possible to combine characteristics similar to the length of the driver by the separation distance between the first and second hinges 110 and 120.

In summary, the ratchet of the present invention additionally guarantees the maneuverability and mobility of the second bar 22, which serves as a handle or handle in the body 20, rather than one hinge, so that the implant, specifically the fixture, is more conveniently placed in the alveolar bone features that can be

4 is a perspective view showing a structure in which first and second stoppers are mounted on first and second bars, respectively, and FIG. 5 is a cross-sectional view illustrating an operating state of the structure of FIG. 4 .

Referring to Figures 4 and 5, the first hinge 110, based on the virtual horizontal line along the arrangement direction of the teeth at the bottom side end around the first hinge 110 in the first bar 21, the above-described virtual It can be seen that the first stopper 30 protrudes and extends along the extension direction of the bottom surface of the hinge part 100 so as not to rotate downward of the horizontal line of .

Further, at the end of the upper surface side of the second bar 22 around the second hinge 120, the second hinge 120 is moved to the upper side of the above-described virtual horizontal line based on a virtual horizontal line along the arrangement direction of the teeth. It is possible to form the second stopper 40 protruding and extending along the extension direction of the upper surface of the hinge part 100 so as not to rotate.

That is, the first stopper 30 is for limiting the rotation angle of the first hinge 110, and the front end of the hinge part 100 is attached to the first stopper 30 extending in the direction of the bottom surface of the front end of the hinge part 100. This is to prevent a phenomenon in which the front end of the hinge part 100 descends excessively in the direction of the adjacent tooth while one part is caught and collides with the adjacent tooth, which encourages troublesome operation.

In other words, the first stopper 30 can be said to prevent the first hinge 110, which has a property of infinite rotation, from being rotated downward of the above-described virtual horizontal line.

The first stopper 30 may exist alone without necessarily being provided at the same time as the second stopper 40 to be described later. However, the single configuration of the first stopper 30 provides an advantage of primarily preventing the fundamental problem, that is, the problem that the tip of the hinge part 100 hits the teeth and makes it impossible to place the fixture itself. can

Furthermore, when the second stopper 40 lifts the front end of the hinge part 100, the second hinge 120 first rises to apply a lifting force to the front end of the hinge part 100, that is, the first hinge 110. It provides properties that can solve the problem of not being communicated properly.

In other words, in the second stopper 40, when the medical worker lifts the second bar 22 to raise the tip of the hinge part 100, the second hinge 120 first rises upward on the imaginary horizontal line, This is to prevent a problem in which the operation of the ratchet of the present invention becomes inconvenient because the lifting force is lost and the corresponding lifting force is not properly transmitted to the first hinge 110 at the distal end of the hinge part 100.

The second stopper 40 functions to hold a part of the rear end of the hinge part 100 to the second stopper 40 in a state in which it extends toward the upper surface of the rear end of the hinge part 100. In other words, as shown in the drawing As can be seen, it can be seen that the second stopper 40 has a structure symmetrical to the first stopper 30 based on the front and rear ends of the upper and lower surfaces of the hinge unit 100 .

The operation of the ratchet of the present invention by the first and second stoppers 30 and 40 will be described in detail with reference to FIG. 5 as follows.

Referring to Figure 5 (a), it can be seen that the ratchet of the present invention is extended in a single state along an imaginary horizontal line in the initial state. Although there may be a problem in which the first hinge 110 rotates downward in the imaginary horizontal line, the first stopper 30 is caught on the bottom surface of the front end of the hinge part 100, so that the hinge part 100 and the second bar It is possible to stably maintain a single state without sagging of (22).

In addition, as can be seen in FIG. 5 (b), when the medical worker lifts the second bar 22 to initially operate the ratchet of the present invention, the second stopper 40 is caught on the upper surface of the rear end of the hinge portion 100 As a result, the second hinge 120 smoothly lifts and rotates the first hinge 110 while transferring the lifting force to the first hinge 110 without the phenomenon that the second hinge 120 rotates in the upward direction first, and as a result, the second bar 22 and the hinge The branch 100 may rise together in a single shape as much as possible.

As shown in FIGS. 5(c) and 5(d), after the first hinge 110 rotates upward, when the medical worker pushes the second bar 22 in the direction of the head 10, the front end of the hinge part 100 And while the first and second hinges 110 and 120 formed at the rear ends are simultaneously rotated, the above-described movability and convenience of operation are provided.

The above-described characteristics can be exhibited by the first and second stoppers 30 and 40 of the present invention, but the first stopper 30 has the hinge part 100 and the second It serves to bear the load of the bar 22, and the second stopper 40 serves to prevent the second hinge 120 from being rotated by the force (operating force) applied by the medical practitioner. Due to the characteristic that the operating force is greater than the load of the hinge part 100 and the second bar 22, the external force may be weighted on the second stopper 40 side rather than the first stopper 30 side, so there is a need to supplement this.

To this end, the second stopper 40 can be made of a material that is more rigid than the first stopper 30, but in this case, the manufacturing cost may increase, so in the present invention, the protrusion (extension) of the second stopper 40 An embodiment in which the length is formed longer than the protrusion (extension) length of the first stopper 30 to reinforce the physical durability of the second stopper 40 is provided.

As a result, it is possible to further reinforce the durability of the second stopper 40 in response to the operating force of the medical worker who overcomes the load of the hinge portion 100 and the second bar 22 .

6 is a conceptual diagram illustrating a coupling structure of first and second packings.

The rotational properties of the first and second hinges 110 and 120 of the present invention do not necessarily have to be the same, and the rotational properties of the second hinge 120, which has the property of first receiving the operating force of the medical worker and rotating first, are the first hinge 110 ), it is preferable to limit the rotational property.

Here, 'rotation' is not the rotation angle, but the possibility that the first and second hinges 110 and 120 can rotate when the same force is applied, that is, the property of rotating while overcoming the static frictional force and the kinetic frictional force. In the 2 hinges 110 and 120, an embodiment in which the frictional force between the first and second hinge holes 111 and 121 and the first and second hinge pins 112 and 122 is adjusted may be proposed.

Specifically, the first packing 130 is between the first hinge hole 111 and the first hinge pin 112, and the second packing 140 is between the second hinge hole 121 and the second hinge pin 122. ) can be installed.

The first and second packings 130 and 140 provide a basis for adjusting the rotational properties of the first and second hinges 110 and 120 by applying a frictional force.

Furthermore, since the friction coefficient of the second packing 140 is greater than that of the first packing 130, the rotatability of the second hinge 120 may be more limited than that of the first hinge 110.

In other words, the surface friction force of the second packing 40 is greater than that of the first packing 30, which means that the second packing 140 can take a stiffer state than the first packing 130.

As a result, the second hinge 120, which first receives the operating force of the medical worker, rotates more easily than the first hinge 110, thereby minimizing the problem of not properly transmitting the operating force to the first hinge 110. can

The aforementioned first and second packings 130 and 140 are preferably made of an elastic material in order to absorb shock caused by an external force as well as impart frictional force.

Such an elastic material may be manufactured by differentially processing the coefficient of friction of the first and second packings 130 and 140 while being made of various engineering plastics having elasticity.

Furthermore, as described above, it is preferable that the second packing 140 has stronger elasticity than the first packing 130. For this purpose, the second packing 140 may be made of a double elastic material.

Referring to FIG. 6 , the second packing 140 includes a base 141 made of an elastic material in contact with the inner circumferential surface of the second hinge hole 121, and is laminated on the base 141 to form a second hinge pin 122. It can be seen that the wrapping may include an elastic auxiliary layer 142 made of a material having a higher elastic modulus than the base 141 by wrapping.

The base 141 may be made of various known elastic materials, for example, engineering plastics having elasticity such as rubber and polyurethane, and is not limited to a specific elastic material. However, as described above, the second packing 140 is made of a material having a higher surface friction coefficient than the first packing 130, of course.

The elastic auxiliary layer 142 includes acrylonitrile as an active ingredient.

Acrylonitrile is a raw material widely used in the manufacture of plastics, adhesives and synthetic rubber, and in the present invention, as a monomer of a polymer providing elasticity, it can provide a function of enhancing elasticity.

In addition, acrylonitrile not only provides workability improvement performance, but also has an excellent elastic modulus compared to conventional thermoplastic elastomers, and has excellent pressure processing characteristics when pressure is applied from the outside.

Therefore, when the elastic auxiliary layer 142 containing such acrylonitrile is laminated on the base 141, not only the workability of the second packing 140 is improved, but also the strong manipulation force of medical workers as well as other external impacts are applied. Shock absorbing effect can be expected by the elasticity.

Furthermore, the elastic auxiliary layer 142 may further include an additional composition in addition to acrylonitrile, such an elastic auxiliary layer 142 is a step of preparing a first solution (S21), a step of preparing a second solution (S22) , It can be manufactured through the step (S23) of completing the elastic auxiliary layer.

(S21) preparing a first solution

First, poly (2-ethylhexyl acrylate) (P2EHA: poly (2-ethylhexyl acrylate)) 10 to 35 parts by weight, methacrylonitrile (methacrylonitrile) 25 to 40 parts by weight, acrylonitrile (acrylonitrile) 20 to 35 parts by weight A first solution is prepared by mixing 50 parts by weight.

Poly(2-ethylhexyl acrylate) is a polymer added to improve processability, and has an excellent modulus of elasticity compared to conventional thermoplastic elastomers, and provides excellent pressure processing characteristics when pressure is applied from the outside.

Methacrylonitrile is widely used as a raw material for synthetic rubber and as a synthetic raw material for acids, amides, amines, and esters. In the present invention, it is added as a monomer of the polymer constituting the elastic auxiliary layer 142.

As described above, acrylonitrile is added as a polymer monomer constituting the elastic auxiliary layer 142 together with methacrylonitrile, and serves to improve processability and elasticity of the second packing.

(S22) preparing a second solution

Next, 80 to 95 parts by weight of the first solution, 5 to 15 parts by weight of β-cyclodextrin hydrate, and 1 to 10 parts by weight of sodium dodecylbenzenesulfonate are mixed to obtain a second solution. prepare a solution

β-Cyclodextrin hydrate is a form of cyclodextrin, which is crystallized with water as a hydrate of β-cyclodextrin in which seven glucose chains are formed. It performs the function of a Pickering emulsifier to help polymerization of methacrylonitrile and acrylonitrile.

In the case of sodium dodecylbenzenesulfonate, it is a nonionic surfactant added to increase the mixing properties of various materials included in the elastic auxiliary layer 142, and emulsification and mixing properties increase according to the addition of sodium dodecylbenzenesulfonate. .

(S23) Step of completing the elastic auxiliary layer

Finally, 85 to 93 parts by weight of the second solution, 1 to 10 parts by weight of sodium magnesium silicate, and 3 to 8 parts by weight of ethylene glycol are mixed to complete the elastic auxiliary layer 142 do.

Sodium magnesium silicate is a montmorillonite-based synthetic clay mineral. It is used as a bulking agent and binder to increase adhesiveness and at the same time serves as a filler to improve the strength of the coating film containing the elastic auxiliary layer 142. there is.

Ethylene glycol is added to enhance the stability after being laminated on the base 141 by combining the flexibility of the elastic auxiliary layer 142 and to increase the mixability of the aforementioned compositions included in the elastic auxiliary layer 142 .

Therefore, according to the additional composition and manufacturing process of the elastic auxiliary layer 142, not only the elasticity of the second packing 140 is further strengthened in the state of having a base capable of reinforcing the frictional force than the first packing 130, but also the base ( 141) can provide lamination stability and convenience in processing.

The aforementioned elastic auxiliary layer 142 is laminated on the base 141 via an adhesive layer, and various known adhesives may be applied to the adhesive layer.

In particular, it is more preferable that the adhesive layer contains an adhesion modifier containing polymethyldiphenylsiloxane.

Polydimethyldiphenyl siloxane (Polydimethyldiphenyl siloxane) is a curable siloxane that has a property that can modify the surface of the base 141, thereby strengthening the adhesive strength of the adhesive layer so that the elastic auxiliary layer 142 is firmly attached to the surface of the base 141. It is possible to provide properties that can be attached.

Additionally, the adhesion modifier can be fabricated by the following process while including additional compositions.

Specifically, the adhesion modifier is characterized in that it is prepared through the steps of preparing a first solution, preparing a second solution, and completing an adhesion modifier.

(S41) preparing a first solution

The first solution is basically prepared by mixing 50 to 70 parts by weight of polyisobutylene, 30 to 40 parts by weight of polydimethyldiphenyl siloxane, and 20 to 30 parts by weight of ethanol.

Polyisobutylene is a synthetic rubber composed of a polymer of 2-methyl-1-propene. It is a colorless or light yellow, tenacious, elastic rubber-like semi-solid, environmentally friendly enough to be added to chewing gum, and harmless to the human body.

In addition, polyisobutylene can prevent defects that are unnecessarily denatured due to external temperature differences, so that the surface of the base 141 made of an elastic material can help maintain an appropriate level of hardness.

Polydimethyldiphenyl siloxane (Polydimethyldiphenyl siloxane), as mentioned above, is a curable siloxane that has the property of modifying the surface of the base 141. As a result, the adhesion of the film generated by the above-mentioned polyisobutylene is increased. It can also play a role in enhancing adhesion.

The aforementioned polyisobutylene and polydimethyldiphenyl siloxane are dissolved in ethanol as a solvent to form a first solution.

(S42) preparing a second solution

Next, a second solution is prepared by mixing 60 to 80 parts by weight of the first solution, 15 to 20 parts by weight of methylethylketone, and 5 to 20 parts by weight of saponin.

15 to 20 parts by weight of methylethylketone included in the second solution can be used as a resin-based solvent to increase the mixing stability of the resin-based materials added to the second solution and at the same time play a role as an adhesive to improve the film quality. adhesion can be increased.

Saponin, which is added in addition, is commonly known to be included in ginseng a lot, and serves as an eco-friendly surfactant and thickener, thereby increasing the stability of the solution when added and increasing the viscosity of the adhesive modifier produced.

(S43) Completing the Adhesion Modifier

Finally, 80 to 90 parts by weight of the second solution, 5 to 15 parts by weight of Sophorolipid, and 5 to 10 parts by weight of Surfactin are mixed to complete the adhesion modifier.

The sophorolipid added at this time is a bio-friendly and environmentally friendly glycolipid-based surfactant, and the stability of the adhesion modifier prepared by adding the sophorolipid can be maximized.

In addition, Surfactin, which is added, is a strong amphoteric surfactant, which is an antibacterial and antiviral substance that increases the mixability of the solution and at the same time has antibacterial properties. When added to the adhesion modifier, it can maximize the antimicrobial properties of the solution .

In summary, when such an adhesion modifier is added, the effect of forming a film can be maximized and stable mixing of the substances included can be expected. It provides a characteristic capable of efficiently protecting the second packing 140 as well as the elastic auxiliary layer 142 from contamination of the second packing 140 as well as bacteria and viruses.

As described so far, the configuration and operation of the ratchet for implantation including multiple hinges according to the present invention have been expressed in the above description and drawings, but this is only an example and the spirit of the present invention is not limited to the above description and drawings.
