The present invention relates to a suture device used to suture a laparoscopic surgery site, and more particularly, a laparoscope configured to quickly and safely suture a laparoscopic surgery site with a simple operation while preventing internal organs from being damaged by the tip of the needle. It relates to a surgical suture device.

Laparoscopic surgery is a surgery that is performed by observing the inside of the patient's abdominal cavity by inserting a laparoscope through the incision by cutting the abdomen about 0.5 ~ 1 cm to the patient's abdomen.

Laparoscopic surgery is applied to gallbladder resection, biliary stone removal, hepatic stone removal, appendectomy, and various long-term tumor resection.It has less postoperative pain and less complications such as intestinal palsy than open surgery. It is widely used due to its short recovery period and the advantage of only small scars.

Laparoscopic surgery involves inserting a trocar into the holes formed in the patient's abdomen, then injecting a gas such as carbon dioxide through one trocar to create relief in the abdominal cavity to secure a surgical space, and through another trocar. The endoscopic or surgical instrument is inserted to observe the inside of the patient's abdominal cavity with an external monitor, and after the laparoscopic surgery is completed, the inserted trocar is removed and the sutured incision is closed with a suture.

Sutures in laparoscopic surgery sites have generally been performed by gripping the needle with forceps and then through the surgery site with the needle to suture the surgery site with a suture connected to the needle. However, the method of gripping the needle by forceps with a forceps may not only cause the sewing process to be considerably cumbersome and take a long time to suture, but also may cause a problem that the internal organs are stabbed and damaged by the sharp tip of the needle during the suture process.

As a method for solving such a problem and more easily suturing a laparoscopic surgical incision site, a method of using a suture aid provided with a guide device for guiding insertion of a suture needle has been proposed (see Patent Document 1).

In addition, when the operation unit 75 is pressed, it is positioned in an unexpanded state (relaxed state) as shown in FIG. 3B, and is configured to insert or remove the guide device 50 into the body without interference.

4A to 4F, the operation of the laparoscopic suture aid 10 is exemplarily illustrated. In order to suture, the guide device 50 must first be inserted into the trocar 20 inserted into the abdomen of the patient (see FIG. 4A). At this time, the guide device 50 is the operation unit 75 mounted on the rear portion is pressed so that the expansion unit 70 is inserted in the unexpanded state as shown in Figs. 3b and 4a. After that, when the insertion of the guide device 50 is completed and the pressurization of the operation unit 75 is stopped, the expansion part 70 is expanded outward and the guide device 50 is separated by the expansion part 70 from the outside. Can be prevented (see FIGS. 4B and 4C).

When the guide device 50 is inserted into the abdomen and fixed as described above, the trocar 20 is removed and the guide device 50 is pulled outward to closely contact the inflated part 70 of the guide device 50 to the inner wall of the abdomen.
