Description

Trocar for single port surgery

The present invention relates to a trocar for laparoscopic surgery, and more particularly, an auxiliary insertion unit capable of freely moving surgical instruments, and additionally inserting surgical instruments or extracting relatively large resected tissue or foreign bodies in the case of complex surgery. It is provided, and relates to a single-port surgical trocar that can minimize the interference between the entrance and exit the surgical instrument gas enters.

In general, laparoscopic surgery is a method of drilling a small hole in the abdomen of the patient and observing the inside of the abdominal cavity through the hole, and performing general surgery and renal cystectomy such as gallbladder resection, appendectomy, stone removal, and colon cancer It is widely used in urological and gynecological surgeries such as nephrectomy and stone removal.

Conventional laparoscopic surgery drills multiple holes in the abdomen, inserts trocars into each hole, and penetrates the trocar one to one through surgical instruments such as endoscopes, gas injectors, electric cauterizers, forceps and cutters, etc. After insertion, the operation was performed while observing the inside. That is, the conventional trocar has a single channel structure in which only one surgical instrument is inserted through one trocar.

Laparoscopic surgery requires at least three surgical instruments. The first is laparoscopic forceps to hold tissue during surgery, the second is endoscopic for doctors to observe the inside of the abdominal cavity, and the third is a therapeutic device for directly treating the patient's affected area (e.g., electric cauterizer, ultrasound generator, cutter) Etc.). In order to solve this problem, a trocar with three ports has been developed and used.

However, in the case of complex laparoscopic surgery should use more than four surgical instruments. For example, in the case of an operation that requires drug administration while removing, an endoscope is essential, and one forceps to hold the extraction site is required, and a cutter to cut the extraction site is required. Then, a drug injector for administering the drug to the cut site is required. That is, four surgical instruments are used, and when using a trocar having three ports, there is a disadvantage in that the medicine is injected by removing the cutter or forceps and inserting a drug injector after cutting the extraction site. Accordingly, there is a problem that the operation is delayed or the bleeding is severe.

In another example, at least four surgical instruments are required for an operation in which one tissue is to be incised and the incision is opened to both sides to cut out the area to be extracted within the tissue. That is, an endoscope, a cutter capable of cutting and cutting, and two forceps to open the incision and catch and pull out the extract. In this case, a trocar with at least four ports is required, which has not been developed until now, which causes a problem in that an additional single hole trocar of a single channel structure is installed by drilling another hole in the abdomen. Therefore, further bleeding occurs and there is a problem that scars increase in the abdomen of the patient and further, healing is slow.

In another example, an apparatus for lifting or pushing other organs is necessary to secure an operation field during intraperitoneal surgery. For example, the lower end of the right kidney surgery covers the right kidney, so in addition to the necessary laparoscopic instruments, such as endoscopes, forceps, and cutters, there may be a need for forceps or glassperes that can be towed. This is a necessary instrument for surgery, and in the case of a single laparoscopic trocar in which only three conventional surgical instruments can be inserted, another single channel trocar must be used in order to use additional surgical instruments. There was no choice but to go through the hole. The problem according to this is the same as described above.

The present invention has been made to solve the above problems, in the case of complex laparoscopic surgery can be additionally installed in the guide port, providing a wide working space to minimize the interference between the surgical instruments can be easily operated The purpose is to provide a single port surgical trocar.

The present invention, the shape is deformed by the external force and is formed of an elastic material so that the shape is restored to its original state when the external force is removed, three insertion ports for inserting a plurality of surgical instruments on the top, and at least one end is protruded end A secondary insertion portion of the main body is formed at a lower end thereof and has a spherical or hemispherical shape to minimize interference between surgical instruments to provide a wide space therein; And a guide port coupled to each insertion hole to guide the surgical instrument, wherein the auxiliary insertion portion cuts an end portion of the auxiliary insertion portion and removes an extract or a foreign object into the surgical instrument through the cut auxiliary insertion portion, or four or more surgical instruments are provided. It is achieved by a single-port surgical trocar characterized by cutting the end of the auxiliary insert if necessary and inserting a guide port into the cut auxiliary insert.

In addition, the main body 10 is formed with a detachable portion 15 which protrudes outwardly so that the periphery of the opening of the main body 10 is fitted so that the fixing portion 30 is fitted, and the detachable portion 15 has one of the fixing rings 32. At least one locking step 15a may be formed on an outer surface of the detachable part 15 to prevent the fitting part 30 from being detached from the detachable part 15.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the single port surgical trocar 1 according to the embodiment of the present invention includes a main body 10 and a guide port 20. The apparatus may further include a fixing part 30 detachable from the main body 10 and an entrance part 40 installed on an outer surface of the guide port 20 to inject or discharge air or gas into the main body 10. .

The main body 10 has a substantially spherical shape and has a large space therein, three insertion holes 11, 12, and 13 are protruded from the top, and the auxiliary insertion portion 14 protrudes from both sides of the insertion hole 11. The lower end is formed by opening. That is, the insertion holes 11, 12, 13 are formed in a triangle arranged on the top of the main body 10 when viewed in plan to minimize the interference between the surgical instruments (5), the surgical instrument (5) is additionally installed In order to easily arrange them in a row, two auxiliary insertion portions 14 with closed ends are arranged to protrude from both sides of the insertion hole 11 at the rear thereof, and the diameter of the sphere for easy operation of the surgical instrument 5 is formed. It may be formed in approximately 90mm to 110mm. In order to perform the operation, a hole is opened in the abdomen of the human body, and the fixing portion 30 is inserted into the lower end of the main body 10 so that the main body 10 is wrapped around the open abdomen and fixed to the abdomen while maintaining the open state. The detachable part 15 detachably protrudes downward. In addition, the locking jaw 15a is formed in two stages on the outer surface of the detachable part 15 to prevent the fixing part 30 from being fitted out. In addition, the main body 10 may be formed of a material such as rubber, silicone, or latex so that the shape of the main body 10 may be changed by an external force so that the user may easily manipulate the surgical instrument 5 during surgery, and then restored when the external force is removed. It can be made transparent so that the inside is visible. Accordingly, when the surgical instruments 5 are inserted and operated, interference between the surgical instruments 5 can be minimized, and the surgical instruments 5 can be easily manipulated. Here, the insertion holes (11, 12, 13) and the auxiliary insertion portion 14 may be formed in a different size of the inner diameter to use a variety of surgical instruments (5). In addition, although the auxiliary insertion portion 14 is used when using four or more surgical instruments (5), it is also used as the discharge passage of the extract or foreign matter. Detailed description thereof will be described later.

The guide port 20 is fitted into three insertion holes 11, 12, and 13, respectively, and includes a first port 21, a second port 22, and a third port 23.

The first port 21 is formed in a substantially cylindrical shape so that the surgical instrument 5 is inserted and fitted into the insertion opening 11 formed at the rear of the upper end of the main body 10.

The second port 22 is formed into a cylindrical shape having a smaller inner diameter than the first port 21 and is fitted to the insertion hole 12 formed on the upper left side of the main body 10. For example, in the case of a surgical instrument 5 such as an electric cauterizer 51 capable of cutting and hemostasis at the same time, the size of the port need not be large. Therefore, when the surgical instrument 5 is small, it is desirable to minimize the interference between the guide ports 20 by using a small port.

The third port 23 is formed in a cylindrical shape having the same size as the inner diameter of the first port 21 and fitted into the insertion hole 13 formed at the upper right side of the main body 10.

Here, the guide port 20 may be installed to protrude from 35mm to 40mm from the upper end of the main body 10 so as to easily manipulate the surgical instrument (5).

The above-described guide port 20, the opening and closing means 24 is provided in the guide port 20 to open only in one direction, that is, the inner direction of the main body 10. The main body 10 is installed in the opened abdomen, and air or gas is injected into the main body 10 to inject air or gas into the abdomen so as to expand the internal space of the abdomen. Since air or gas may leak through 20, the opening and closing means 24 which opens only inside the main body 10 is installed inside the guide port 20 to seal the air or gas. Here, since the guide port 20 uses a well-known and widely known, detailed description of the structure and the operating state will be omitted.

In addition, although the guide port 20 mentioned above can be inserted and used in the insertion slot 11, 12, 13, in order to improve the airtightness between the main body 10 and the guide port 20, the main body 10 and the insert port method are performed. Can be combined integrally.

The fixing part 30 is formed in a predetermined length to connect the inside of the human body and the outside of the human body by drilling a hole in the abdomen of the human body and opening the abdomen to open the abdomen and bent well or having a predetermined elasticity. ) And a fixing ring 32 made of a resilient material having strong restoring force is installed at the upper and lower ends of the connecting part 31 so that the openings at the upper and lower ends of the connecting part 31 are open and communicate well. 15) is fitted. That is, the fixing ring 32 installed at the upper end of the connection part 31 is fitted to be disposed on the upper end of the locking step 15a of the detachable part 15, and the fixing ring 32 installed at the lower end of the connection part 31 is crushed and opened. It is used to fit inside the abdomen. Accordingly, the inside and the outside of the abdomen may be connected through the fixing part 30, and surgery may be performed through the main body 10. Here, the connecting portion 31 is elastic and can be stretched according to the skin (S) thickness of the patient, and in the case of a thin skin (S) thickness, the connecting portion 31 is rolled up by the fixing ring 32 and the connecting portion 31. The length of can also be adjusted. Detailed description thereof will be described later.

The entrance part 40 is an entrance pipe that injects air or gas into the body 10 to expand the internal space of the abdomen by injecting air or gas into the inside of the abdomen and minimize interference with the surgical instrument 5. A 41 is connected to the side of the third port 23, and a valve 42 for opening and closing the access pipe 41 is installed at the upper end of the access pipe 41. Accordingly, the valve 42 is opened and the inner space of the abdomen is expanded while injecting air or gas into the entrance tube 41 to easily operate with the surgical instrument 5. Particularly, when there is an extract, when the main body 10 is removed from the fixing part 30 to remove the extract or wipe the blood with gauze, etc., the entrance part 40 is in a high position, so that the worker uses the tool, that is, Tweezers (not shown) or the like can be prevented from being caught in the tube (not shown) connected to the entrance 40. In addition, the entrance 40 may be further installed on the side of the second port 22, as shown in FIG. This is to make it possible to remove the smoke generated during cauterization through a gas entrance other than the inlet through which gas is injected when the operation vision is blurred due to the cautery smoke during surgery. At this time, the internal pressure is automatically adjusted by an external device (not shown).

For example, four or five surgical instruments 5 may be used for complex laparoscopic surgery. That is, three surgical instruments 5 may be used through the guide port 20, but in order to use the surgical instrument 5 additionally, an additional additional guide port 20 is required. In order to solve this problem, as shown in FIG. 4, the end of the auxiliary insertion part 14 may be cut out with a knife or scissors, and then inserted into the guide port 20. Accordingly, in the case of complex laparoscopic surgery, the end of the auxiliary insertion section 14 is cut off, and the required number of guide ports 20 are inserted in the auxiliary insertion section 14 to be set in advance, or unexpected surgical instruments 5 are removed during surgery. If you need to use additionally, you can cut the end of the auxiliary insertion portion 14 in place immediately by inserting the guide port 20. Therefore, the present invention can use four or more surgical instruments 5 at a time without changing the surgical instruments 5 even in complicated surgery. For example, if you need to use the endoscope 52, electric cauterizer 51, forceps 53, and drug injector (not shown) for laparoscopic surgery, only three ports are insufficient. In other words, any one of the surgical instruments (5) should be replaced. However, the single port surgical trocar 1 of the present invention can use two ports additionally, so that a total of five surgical instruments 5 can be used. Accordingly, the operation time can be shortened, and even if a crisis occurs during the operation, it is possible to cope quickly.

Referring to Figure 5 will be described in detail the state of use of the single-port surgical trocar 1 according to an embodiment of the present invention.

First, determine the condition of the patient and determine how many surgical instruments (5) to use. For example, when four surgical instruments 5 need to be used, the guide port 20 is additionally installed in the auxiliary insertion part 14 to set the single port surgical trocar 1 according to the embodiment of the present invention. do. Here, the guide port 20 is inserted into the auxiliary insertion portion 14 so that the guide port 20 is inserted into the guide port 20 and tightened with a band (not shown) or tied with a string (not shown) to guide insertion (20) It can be fixed to the part 14.

After the setting is completed by drilling a hole in the skin (S) and then open one of the fixing ring 32 of the fixing part 30 is inserted into the drilled hole. The inserted fixing ring 32 is restored and is caught by the lower end of the skin S. The body 10 is inserted into the detachable part 15 by inserting the fixing ring 32, which is released outside the body, so that the main body 10 comes into close contact with the abdomen. Secure to the abdomen. Here, when the thickness of the patient's skin (S) is standard or thick, the fixing part 30 may be stretched to a predetermined degree and used as it is, but when the patient's skin S is thin, the connection part is connected to the fixing ring 32 outside the body. Roll up (31) to adjust the length.

When the single port surgical trocar 1 of the present invention is fixed to the abdomen, the endoscope 52 is inserted into the first port 21, and the electric cauterizer 51 is inserted into the second port 22 having the smallest inner diameter. Insert the forceps 53 and the like into the remaining ports to proceed with the surgery.

If the fixed type does not reduce the length of the fixing part 30, the lower end of the fixing part 30 by pressing the organ in the stomach to cause another risk to the patient, or the fixing part 30 is loosely inserted into the abdomen Trocar flow can occur. However, the single-port surgical trocar 1 according to the embodiment of the present invention has elasticity that the fixing part 30 can be increased to a predetermined degree, but the length can be adjusted to prevent the fixing part 30 from pressing the organ. can do. In addition, since the guide port 20 can be additionally installed so that various surgical instruments 5 can be used before or during surgery, it is possible to quickly cope with dangerous moments that may occur during the operation, and various surgical instruments at once ( 5) can be used to shorten the operation time. For example, when removing the extract by separating the main body 10 and the fixing portion 30, the surgical instruments 5 are bound to move with the main body 10. In other words, the surgical instruments 5 are forced to retreat from the surgical site and the operation is stopped, and after removing the foreign substance, the surgical instrument 5 is set back to its original state and the operation must be resumed. To solve this, the auxiliary insertion part 14 is cut out, the forceps 53 are inserted into the cut auxiliary insertion part 14 to pick up the extract, and then the extraction is pulled out through the auxiliary insertion part 14 to remove the extract. You may. In this case, it is possible to eliminate the process of retreating the surgical instrument 5 at the surgical site and restoring again, so that the extract can be easily and quickly removed. If the excision is removed by cutting the main body 10, when the air or gas is injected into the main body 10 to expand the body, the injected air or gas leaks into the cut portion of the main body 10. Since a problem arises, it is preferable to cut the end of the auxiliary insertion portion 14 without cutting the main body 10. Of course, the tip of the auxiliary insert 14 is cut off to leak air or gas, but the tip of the auxiliary insert 14 may be picked up with a forceps (not shown) to block the auxiliary insert 14. Accordingly, it is possible to remove the extract while performing the operation can further shorten the operation time.

In particular, when the internal space of the main body 10 is small, the interference between the surgical instruments 5 is severely generated, but the present invention guides the main body 10 to have a spherical shape so as to gather well while minimizing the interference of the surgical instruments 5. The port 20 can be easily disposed and provided with a wide space for operating the surgical instrument 5, and formed of an elastic material having excellent bending and restoring force due to the characteristics of the main body 10 to provide the surgical instrument 5. Can move freely. In addition, when large extracts or foreign substances appear, the main body 10 can be quickly separated from the fixing portion 30, thereby quickly removing the extracts or foreign substances.

In describing the present invention described above, even if the embodiment is different, the same reference numerals are used for the same configuration, and the description may be omitted as necessary.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Shall not be construed as being understood. Therefore, a person having ordinary knowledge in the technical field to which the present invention pertains may easily implement other forms of the present invention within the same scope as the above-described embodiments, or the present invention only by the description of the embodiments of the present invention.
