Laparoscopic Surgery Device {SUTURE APPARATUS FOR LAPAROSCOPIC SURGERY}

The present invention relates to a suture device for laparoscopic surgery. More specifically, the present invention relates to a laparoscopic suture device that can be simply knotted without additional equipment to make a knot when suturing an intraabdominal surgical site after laparoscopic surgery.

In general, laparoscopic surgery is the latest surgical method to treat lesions using surgical instruments while observing the inside of the abdominal cavity by inserting a laparoscope and cutting three or four holes by cutting the abdomen about 0.5 ~ 1㎝ unlike conventional open surgery. .

Laparoscopic surgery is applied to cholecystectomy, cholecystectomy, hepatic stone removal, appendectomy, and various long-term tumor resections, and there are fewer postoperative pains and fewer complications such as palsy than open surgery. The period is 3 ~ 4 days, which is shorter than general surgery, and has been performed because of the small scars.

In order to perform laparoscopic surgery, first, a plurality of trocars are inserted into the abdomen of a patient, and then a gastrointestinal relief is injected by injecting a gas such as carbon dioxide into the abdominal cavity through any one of the trocars to secure a surgical space. Next, using the endoscope and surgical instruments that are inserted through the other trocars to perform the affected area while observing the surgical site.

In such a procedure, a suture device is used to suture an intraperitoneal surgical site, and the suture method includes an extraabdominal ligation and an intraperitoneal ligation.

In the case of the non-abdominal ligation, a strong knot may be formed outside the abdominal cavity, but not only a knot-pusher must be used to push the knot into the abdominal cavity but also takes a long time per unit suture, resulting in a long operation time. There is this.

In the case of the intraperitoneal ligation, in order to facilitate the knot, two or more perforations should be basically applied to the abdominal wall, and in the case of ligation in the abdominal cavity, a laparoscopic forceps for catching a thread must be completed. (See Patent Publication No. 10-2007-1019994 "Tools for Laparoscopic Surgery").

In addition, in the case of conventional extraabdominal ligation and intraperitoneal ligation, all of the sutures used to make a knot had to be used.

Figure 1 shows a conventional laparoscopic suture device, the suture device consists of a forceps for holding a thread or needle, and a body portion including a handle. The process of intraperitoneal ligation using the suture device of FIG. 1 will now be described with reference to FIGS. 2A through 2E.

 Laparoscopic forceps and sutures are inserted once through two perforations for intraperitoneal ligation (see FIG. 2A). Using one of the laparoscopic forceps to hold one end of the thread, to form a knot of the thread on the upper end of the forceps portion of the suture device (see Figs. 2b and 2c). Then, to grasp one end of the thread using the forceps, and put it into the knot of the thread formed on the top of the forceps to make a knot on the surgical site (see Figs. 2d and 2e). Repeat this process to finally form a knot in the surgical site.

Therefore, in the case of extraabdominal ligation, there are disadvantages as described above, and in the case of intraperitoneal ligation, as shown in FIGS. 1 to 2E, the wound of the abdominal wall may take a long time because two or more perforations are applied to the abdominal wall. In addition, the laparoscopic forceps to seize the thread is required separately, and the suture becomes complicated. In addition, the wound may occur due to the collision between the laparoscopic forceps and the suture device, and the operation time also takes a long time. .

In order to solve the above problems, the present invention can be simply knotted without additional equipment to make a knot when suturing an intraabdominal surgical site after laparoscopic surgery, and through the present invention, a new suture method for intraperitoneal ligation. The purpose is to provide a laparoscopic suture device that can provide.

According to the present invention, a needle for holding a thread or a forceps for holding the thread to suture the surgical site; And a body portion extending from the forceps and having a predetermined length and forming a locking portion at one side thereof.

On the other hand, the engaging portion has one end coupled to one side of the body portion, the other end includes a locking jaw formed extending in the direction of the tongs portion, the other end of the locking jaw is characterized in that it does not contact the body portion do.

Meanwhile, one end of the locking jaw is rotatably coupled to one side of the body portion and the ball joint.

On the other hand, the locking portion is built in one side of the body portion is open in the outer direction of the body portion, the locking groove body to form a plurality of locking grooves therein; And a locking projection formed at one end thereof so that the locking projection is coupled to the locking groove, and the other end of the locking projection extends from the locking projection in the direction of the tongs portion. The other end of the locking projection is fitted with the body portion. It does not touch, the locking step including the locking projection is characterized in that the reciprocating movement through a plurality of locking grooves of the locking groove body.

On the other hand, the engaging portion is the engaging body is coupled along one outer peripheral surface of the body portion; And a locking jaw coupled to one end of the locking body and extending from the one end of the locking body in the direction of the tongs, wherein the locking jaw does not contact the body portion.

Meanwhile, the locking jaw is rotatably coupled to one end of the locking body by a ball joint.

According to the present invention, not only can you make a knot without additional equipment to make a knot when suturing a surgical site after laparoscopic surgery, but also the suture operation itself becomes simple, and the suture process can be performed using only a suture device. It has the effect of reducing the probability of wounds on the site.

In addition, when using the suture device according to the present invention there is an effect that can be much shorter than the time required for suture after performing a conventional laparoscopic surgery.

In addition, according to the present invention can be used only as necessary suture (thread) used for suture after laparoscopic surgery has the effect of preventing waste of the suture (thread).

In addition, according to the present invention, since only a single perforation is formed in the abdominal wall, the suture process can be easily performed, thereby reducing the wound occurring in the abdominal wall.

Referring to FIG. 3, the laparoscopic suture device 10 includes a forceps part 100 and a body part 200. The forceps part 100 serves to hold a needle or a thread for threading the surgical site. That is, the forceps part 100 may catch a thread, or catch a needle that is threaded. Needles typically use hook shapes as shown in the figure. This hook-shaped needle can be seen as a suitable form for suture the surgical site. The forceps part 100 can be easily held by the needle or thread while repeatedly closing and opening by the operation of the handle part (not shown). In addition, it is also possible to pull the thread or needle using the forceps unit 100.

The body portion 200 extends from the forceps portion 100 to have a predetermined length, and forms a catching portion 300 on one side of the body portion 200. The body portion 200 is required to have a constant length for suture of the surgical site after penetrating into the abdominal cavity. A handle portion (not shown in the drawing) is attached to the end of the body portion 200, and the tong portion 100 is opened and closed by the operation of the handle portion.

4A and 4B, one end of the locking portion 300 is coupled to one side of the body portion 200, and the other end of the locking portion is formed to extend in the direction of the tongs portion 100 from the one end. It includes 310, the other end of the locking step 310 does not contact the body portion 200. The locking jaw 310 is a component required for the knot of the thread to suture the surgical site. The locking jaw 310 is formed integrally with the body portion 200 can be made easier when the knot is built compared to the conventional laparoscopic surgical suture. In addition, the locking jaw 310 serves as a carrier of the knot ring for pushing the knot ring formed outside the abdominal cavity to the abdominal cavity. This will be explained in detail in the operating state to be described later.

5A and 5B, one end of the locking jaw 310 may be rotatably coupled to one side of the body portion 200 and the ball joint 320. The locking jaw 310 can be freely moved up and down or left and right through the ball joint 320. If necessary, it may be more easily sutured by freely adjusting the angle of the locking jaw 310 for the suture of the laparoscopic surgical site after laparoscopic surgery.

6A and 6B, the catching part 300 is embedded in one side of the body part 200 and is open in the outward direction of the body part 200 and has a plurality of catching grooves 331 therein. The engaging groove main body 330 to form a, and the engaging projection 311 is formed at one end, the engaging projection 311 is coupled to the engaging groove 331, the other end is the tongs from the engaging projection 311 It includes a locking step 310 is formed extending in the direction of the portion (100). The other end of the locking jaw 310 is not in contact with the body portion 200, the locking jaw 310 including the locking projection 311 is a plurality of locking grooves 331 of the locking groove body 330 It will travel back and forth. Therefore, as the locking jaw 310 is reciprocated from one side of the body portion 200, the thread wound on the body portion 200 of the lower portion of the locking jaw 310 flows down in the direction of the tongs 100 well. . The locking jaw 310 may be moved by a pressing device such as a button (not shown) or by a method such as operating a moving means (not shown) directly by a human hand. In particular, the locking step 310 has the same function as the locking step 310 of Figure 4a.

7A to 7C, the locking portion 300 is coupled to one end of the locking body 340 and the locking body 340, which are coupled along one outer circumferential surface of the body 200. It includes a latching jaw 350 is formed extending from the one end of the main body 340 in the direction of the forceps unit 100. In this case, the locking jaw 340 does not contact the body 200. The locking jaw 350 has the same function as the locking jaw 310 of FIG. 4A. However, the locking jaw 350 is formed integrally with the locking body 340, so that the locking portion 300 including the locking jaw 350 and the locking body 340 is easily separated and coupled to the body 200. It has a structure. Therefore, the locking portion 300 including the locking body 340 and the locking jaw 350 can be separated from the body portion 200, which can be used in combination with a conventional laparoscopic suture.

8A and 8B, the locking jaw 350 may be rotatably coupled to one end of the locking body 340 and the ball joint 360. Through the ball joint 360, the locking jaw 350 can be freely moved up and down or left and right. If necessary, it may be possible to suture more easily by freely adjusting the angle of the locking jaw 350 to suture the surgical site after laparoscopic surgery.

Referring to Figures 9a to 9i will be described the operating state of the laparoscopic surgical suture device 10 according to the present invention.

First, the thread is inserted into the needle hole, and the threaded needle is inserted through the trocar using the suture device 10 and inserted into the surgical site in the abdominal cavity, and then the surgical site is sewn (see FIG. 9A). And after pulling out the needle and the suture device 10 including the thread to the surgical site to the outside of the abdominal cavity, the thread is wound at least once on the body portion 200 of the lower portion of the locking jaw 310 (see Fig. 9b). At this time, the thread may be wound once, or may be wound twice. If the case is wound twice, it becomes the shape of a knot in the shape of a palm, which has the effect of making a knot more firmly at once.

Then, the suture device 10 including the thread wound on the body portion 200 of the lower portion of the locking jaw 310 is inserted into the abdominal cavity through the trocar, and then while pulling the thread attached to the needle by hand from the outside of the abdominal cavity as appropriate. Do not let the thread wound on the body portion 200 of the lower portion of the jaw 310 in the direction of the forceps portion 100, and then grasp the end of the thread opposite the thread attached to the needle using the forceps portion 100 at the same time The thread wound on the body portion 200 of the lower portion of the locking jaw 310 while letting the thread attached to the needle by hand from the outside is lowered in the direction of the tongs portion 100 (see FIG. 9C). As such, the locking jaw 310 serves as a carrier of the knot ring for pushing the knot ring formed outside the abdominal cavity to the inside of the abdominal cavity.

And while inserting the end of the opposite thread into the inside of the thread wound on the body portion 200 of the lower portion of the locking jaw 310 while pulling the thread attached to the needle by hand to knot the surgical site (Fig. 9d and Fig. 9e).

Then, the needle and the suture device 10 including the thread stitching the surgical site in the same manner as done in Figure 9b to the outside of the abdominal cavity, and then at least once the thread on the body portion 200 of the lower portion of the locking jaw 310 It winds up abnormally (refer FIG. 9F).

And the suture device 10 including the thread wound on the body portion 200 of the lower portion of the locking jaw 310 in the same manner as done in Figure 9c into the abdominal cavity through the trocar, and attached to the needle by hand from the outside of the abdominal cavity While pulling the thread properly, the thread wound on the body portion 200 of the lower portion of the locking jaw 310 does not flow down to the forceps portion 100, and then the end of the thread opposite to the thread attached to the needle 100) while holding the thread attached to the needle by hand from the outside of the abdominal cavity at the same time to allow the thread wound on the body portion 200 of the lower portion of the locking jaw 310 to descend toward the tongs portion 100 (see Fig. 9g). ).

9D and 9E, the end of the opposite thread is inserted into the inside of the thread wound on the body portion 200 of the lower portion of the locking jaw 310 while pulling the thread attached to the needle by hand. Knot the surgical site (see FIGS. 9H and 9I).

Thus, when using the laparoscopic suture device 10 as shown in Figure 9a to 9i, there is an effect that can easily suture the surgical site without having to separate the forceps and the suture device for holding a separate thread.

Therefore, in case of using a conventional suture device (see FIGS. 2A to 2E), two or more holes are made in the abdominal wall to suture the surgical site in the abdominal cavity, and the surgical site is inserted with the forceps and the suture device that hold the thread in the two holes. Because of sutures, not only does the operation take a long time, but there is a disadvantage that the wound is likely to be wound around the surgical site due to the collision between the holding device and the suture device. In the present invention, all the above disadvantages can be overcome. That is, one hole (single perforation) is made in the abdominal wall, and through the one hole, only the suture device 10 of the present invention can be safely closed without injury to the surgical site as well as can significantly shorten the operation time. It works.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Therefore, the embodiments disclosed in the present specification are intended to illustrate rather than limit the present invention, and the scope and spirit of the present invention are not limited by these embodiments.
