Description

A Ligation Clip for Surgery [

The present invention relates to a surgical ligature clip, and more particularly, to a ligature clip of titanium material for ligating a region such as a blood vessel in an internal surgery procedure.

The ligation clip refers to a V-shaped clip made of stainless steel, platinum, titanium or an absorbent material that binds bleeding blood vessels. A plurality of ligation clips are arranged in a sequence on the clip applier and can be sequentially ejected for ligation of the blood vessels during the surgical procedure. The ligature clips are stored in clip holders, placed in clip appliers before use, pasteurized and used for ligating blood vessels. As such, the ligation clip is sterilized in a state where it is placed in the clip apple, and is moved along the path formed in the apple lira in the surgical procedure and used for ligation of blood vessels. Therefore, the ligation clip should be made based on the material characteristics and structural characteristics.

Prior art relating to ligature clips is US 5,219,353. The prior art includes a base having an end that extends rearwardly and simultaneously extends upwardly to define a free end; An edge formed between the free end and the front end portion of the base; And an intermediate portion extending from a rear end portion of the free end base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

1 shows an embodiment of a surgical ligature clip 10 according to the present invention.

1, the ligature clip 10 according to the present invention includes a linear reference apex portion 11, a pair of protruding portions 11, which extend in both directions of a reference apex portion 11, Curved surface stretching regions (12a, 12b) extending in a curved shape in different directions; And contact linear portions 13a and 13b extending to face each other from the respective curved surface stretching regions 12a and 12b and include one boundary region of the reference vertex portion 11 and the curved surface stretching regions 12a and 12b, The two boundary regions of the elongated regions 12a, 12b and the contact linear portions 13a, 13b have a smaller cross-sectional area than the other portions.

The ligation clip 10 according to the present invention is used for ligation of blood vessels in a surgical procedure, and a plurality of the ligation clips 10 can be accommodated in the clip appliers and sequentially discharged with the clamp teeth of the clip appliers to ligature the blood vessels. A plurality of ligature clips 10 can be stored in the storage and can be placed on clip appliers for use in a surgical procedure. And clip appliers can be pasteurized with ligation clips. The ligation clip 10 according to the present invention can be applied to ligation of various parts inside the human body.

The ligature clip 10 may be U-shaped, the overall central portion of which is linear, and may extend with a circular or polygonal cross-section, but may preferably extend into a rectangular cross-section. And may be formed in a polygonal shape with one side opened as a whole while being curved or linearly extended on both sides of the center of the reference vertex portion 11.

The reference vertex portion 11 can be curved or linearly extended, and the curved surface or linearly extending length can be determined by the thickness of the blood vessel to be ligatured. Specifically, the thickness of the blood vessel can be determined in the ligation state, and the extension length of the reference vertex portion 11 can be set to correspond to the thickness. And the curved surface stretching regions 12a, 12b can be extended to both sides of the reference vertex portion 11.

The curved extension regions 12a and 12b can extend while forming an angle of 100 to 120 degrees around the reference vertex portion 11 and can extend in a curved shape. The angle of 100 to 120 degrees in the curved shape is such that the angle of the two curved extension regions 12a and 12b is the angle formed by the two straight lines connecting the center of the reference vertex portion 11 and the end points of the curved extension regions 12a and 12b . The inner surfaces of the curved surface stretching regions 12a and 12b correspond to a portion in contact with the human body during the ligation process, and the curved stretching region can be changed into a straight shape in the process of ligation. And the contact linear regions 13a and 13b can be extended from the end portions of the respective curved surface stretching regions 12a and 12b.

The contact linear regions 13a and 13b can extend in a straight line shape and can be made parallel to each other while facing each other. The contact linear regions 13a and 13b can be made in a rectangular or circular cross-section. The surfaces of the contact linear regions 13a and 13b facing each other are in contact with a human body portion such as a blood vessel in the ligation process, thereby enabling hemostasis. The two boundary regions corresponding to the boundary regions of the curved surface stretching regions 12a and 12b and the contact linear regions 13a and 13b can form convex curved surfaces different from the curved surface stretching regions 12a and 12b. Such a structure allows the curved surface stretching regions 12a and 12b to be changed from a curved surface to a straight shape easily in a ligation process and to be capable of ligation. The size of the ligation clip 10 is determined by the open portion formed by the end portions of the pair of contact linear regions 13a and 13b facing each other, and the size of the ligation clip 10 is determined and various specifications such as 5 mm, 10 mm or 12 mm Lt; RTI ID = 0.0 > 10 < / RTI > The ligation clip 10 according to the present invention can be made in various sizes.

Referring to FIG. 1 (b), the ligature clip 10, when received in a clip holder or clip applier, may be U-shaped and may be generally linear when ligated out of the clip applier and ligated. Specifically, the curved stretching regions 12a and 12b become linear as they approach each other around the reference vertex region 11 and the mutually facing surfaces of the contact linear portions 13a and 13b and the curved stretching regions 12a and 12b Can be made linear as they approach each other. And the ligation site (V), such as a blood vessel located inside, may become a ligature. In the process of making the U-shape linear, one boundary region or two boundary regions are formed differently from the convexity of the curved extension regions 12a and 12b, so that a force extending in a direction opposite to the extension direction for contact So that it is prevented from being generated. 1 boundary area or 2 boundary area does not necessarily have to be a curved surface. For example, one boundary region or two boundary regions may be a straight line or a shape approximating a straight line.

The structure of the ligation clip 10 having such a structure as described below to improve the coupling force of the contact linear regions 13a and 13b facing each other in the ligation state will be described.

Fig. 2 shows an example of the structural characteristics of a surgical clipping clip according to the present invention.

Referring to FIG. 2, the inner surface of the reference vertex portion 11 may be linear, and the outer surface may be linear or may be inclined at different angles and intersect at the center. The two linear lengths L2 of the inner surface of the reference vertex portion 11 may be formed to correspond to the thickness of the ligation portion in the ligation state and may be equal to or slightly smaller than the thickness of the ligation portion. Therefore, if pressure is applied to the ligature site, it can be ligated due to the elasticity of the human tissue. Thus, the linear length L2 of the inner surface can be appropriately set on the basis of the state in which the ligature site is ligatured. The one linear length L1 of the reference vertex portion 11 may be larger than the two linear length L2 and the both ends of the one linear length L1 may be larger than the respective curved extension regions 12a and 12b In a direction different from the convex direction of the convex portion. Or when the curved surface stretching regions 12a and 12b are linear. Both ends of the linear length L1 may be convex upward.

Each of the curved surface stretching regions 12a and 12b may have a convex curved shape upward from both ends of the inner surface of the reference vertex portion 11 extending linearly. The vertical extension length L3 of the curved extension regions 12a and 12b may be sufficiently larger than the length of the one linear length L1 and may be 4 linear lengths L4 corresponding to the extension length of the contact linear portions 13a and 13b. Lt; / RTI > Such an extension length can be determined based on the thicknesses of the portions corresponding to the 1, 2, 3 and 4 linear lengths (L1, L2, L3, L4). Specifically, the cross-sectional area along the extending direction of the reference vertex portion 11 is the largest and the cross-sectional area along the extending direction of the curved surface stretching regions 12a and 12b is the smallest.

The total length L3 + L4 of the ligation clip is determined to be a predetermined length, and the smaller the difference in magnitude between the size of the cross-sectional area of the reference vertex region 11 and the cross-sectional area of the curved surface stretching regions 12a, 12b, The smaller the angle formed by the regions 12a and 12b, the greater the difference in length between the 3-line length L3 and the 4-line length L4.

2 (b), a stopper groove 131 is formed at the inner end portion of the first contact linear portion 13a, and a stopper 132 is formed at the inner end portion of the second contact linear portion 13b . The stopper groove 131 may be a triangular groove having a large lower side formed at the end of the first contact linear portion 13a and the stopper 132 may have a projection shape inserted into the stopper groove 131 . By forming the stopper groove 131 and the stopper 132 in the triangular shape as described above, mutual opposing portions of the ligation clip can be prevented from approaching beyond a predetermined gap.

Contact projections 134 and 135 may be formed along the extending direction on the inner surfaces of the first contact linear portion 13a and the second contact linear portion 13b, respectively. The contact protrusions 134 and 135 may be formed in a plurality of contact protrusions 134. For example, a plurality of contact protrusions 134 may be formed on the inner surfaces of the first contact linear portions 13a and the second contact linear portions 13b, respectively . The contact protrusions 134 and 135 may have a function of preventing the movement of the ligature clip in the ligation state, and may be formed into various shapes.

Fig. 3 shows an application example of a surgical ligature clip 10 according to the present invention.

3 (A), displacement regions 15a and 15b can be formed at boundary portions of curved surface extension regions 12a and 12b, displacement regions 15a and 15b correspond to two boundary regions, The convex curved surface may form a convex curved surface different from that of the elongated regions 12a and 12b or may be curved outwardly convex around the ligation portion V when the curved elongation regions 12a and 12b are linear. As a result, the curved stretching regions 12a, 12b and the contact stretching regions 13a, 13b can be elongated in different directions about the ligation portion V accommodated in the ligation clip 10.

Referring to FIG. 3 (B), the ligation site V can be received in the ligation clip 10 for ligation (A). The ends of the contact linear portions 13a and 13b can be brought into contact with each other. The contact linear portions 13a and 13b can be brought into contact with each other with the stopper groove and the stopper engaged, as described above (B). When the end portions of the contact linear portions 13a and 13b are fixed, the contact linear portions 13a and 13b and the curved surface stretch regions 12a and 12b extend in different directions as pressure is applied to the displacement regions 15a and 15b (C), the ligation site (V) accommodated inside can be ligated. Thereafter, the ligation clip 10 becomes entirely linear, and the ligation site 10 becomes entirely linear, so that the ligation site V can be completely ligated.

Depending on the structure of the ligature clip 10, the ligature site V can be ligated in various ways and the invention is not limited to the embodiments shown.

Figure 4 shows an embodiment of a storage bin for a surgical ligation clip according to the present invention.

4, the ligature clip 10 includes a storage body 41, a plurality of separation plates 43 formed in parallel to each other in the interior of the storage body 41, and a lid 42 coupled to the storage body 41, . &Lt; / RTI > A latching protrusion may be formed between each of the separating plates 43, and the latching protrusion may have a shape suitable for receiving the ligation clip. The ligature clip 10 may be stored in its original shape for ligating the ligature site. Ligation clips can then be accommodated in the clip applier during the surgical procedure.

Figure 5 illustrates an embodiment of a clip applier using a surgical ligature clip 10 according to the present invention in accordance with the present invention.

5, the clip applier includes a tube-shaped clip receiving rod 51, a drive unit 52 coupled to the clip receiving rod 51, a clip clamp 54 operated by the drive unit 52, And a clip guide 53 for guiding the ligation clip 10, which is sequentially discharged from the clip receiving rod 51, to the clip clamp 54 by the operation of the drive unit 52.

The ligature clips 10 may be arranged in sequence on the clip receiving rods 51 before being used in the surgical procedure. And the ligation clip 10 can be pasteurized while being accommodated in the clip receiving rod 51. [ In this process, the physical properties of the ligation clip 10 may vary. For example, if the ligature clip 10 does not have sufficient elasticity, the ligature clip 10 may be dislodged from the clip apple while being discharged from the clip receiving rod 51. On the other hand, if the ligature clip 10 has a large elasticity, the ligature of the ligature clip 10 may become unstable. Therefore, the material and construction of the ligature clip 10 need to be made such that the ligature clip 10 maintains adequate elasticity.

For example, the ligating clip 10 can be made of titanium material. However, due to the small elasticity of the titanium material, separation of the ligature clip 10 is difficult to prevent. When made of a titanium material, the ligature clip 10 may have the structure as shown above, and the ligature clip 10 may be prevented from being separated from the ligature clip 10, thereby maintaining the ligation state. In addition, the ligation clip 10 according to the present invention may comprise 3 to 12 wt% nickel in order to supplement the characteristics of the ligation clip 10. Alternatively, the curved elongation zones 12a, 12b can be made of a titanium material comprising 3-12 wt% nickel. At least a portion of the ligation clip 10 is made of nickel-comprising titanium material so that the ligation of the ligation clip 10 during the sterilization process is prevented from changing, while at the same time maintaining a stable ligation state.

The ligation clip according to the present invention allows the ligation clip to stably ligate the blood vessel during the operation according to the material characteristics or the structural characteristics. Further, the ligation clip according to the present invention allows the structure to be maintained regardless of changes in the external environment. Further, the ligation clip according to the present invention can be applied to clip appliers having various structures.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention . The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
