Laparoscopic port site closing apparatus

Abstract

The present invention relates to a laparoscopic port site closing apparatus configured such that a cartridge having a suture thread therein is formed at the front end of a needle guide for laparoscopic port site suturing and that the suture thread is threaded through the tip of a needle, which is guided by the needle guide and penetrates biological tissue, so that when the needle is taken out, the suture thread is extracted along an invasion path and tied outside, thereby suturing a laparoscopic port. In order to be imported into the laparoscopic port, the apparatus is in a tubular shape and comprises: a tubular body provided with needle guides, the needle guides facing to each other and guiding the insertion of the needle; wings arranged at the lower part of the tubular body and being spread and folded through cams; and an operating rod which penetrates the tubular body to spread the wings through rotation and fold the wings through reverse rotation, so as to operate the wings. The apparatus also comprises a replaceable cartridge formed at the lower end of the tubular body and attached to / detached from the operating rod, wherein the cartridge is provided with the wings spread to either side by the operating rod and a compartment having the suture thread therein, the laparoscopic port site closing apparatus is configured such that either end of the suture thread is inserted in the wings and that the ends of the suture thread are hooked to a groove of the needle invading from the outside of a body so as to be extracted to the outside of the body.

Description

technical field [0001] The invention mainly relates to a laparoscopic puncture port closure device. More specifically, the present invention relates to a laparoscopic puncture site closure device configured to provide a cartridge accommodating surgical suture therein at the front end of a needle guide for closing the puncture site; the surgical suture threaded into the needle tip , the needle tip is guided by the needle to pierce body tissue; and when the needle is withdrawn, the surgical suture is drawn along the path the needle penetrated into the tissue, and the surgical suture is tied outside the body of the patient , so that the laparoscopic puncture site can be closed. Background technique [0002] In general, laparoscopic surgery, unlike traditional laparotomy, refers to a surgical technique in which 4 to 6 incisions of about 0.5 to 1.2 cm in size are made on the patient's abdomen and have a 0.5 to 1.2 cm incision. Trocars of diameter and length of 15 to 16 cm are p...

Problems solved by technology

Therefore, the process is inconvenient

A further problem with conventional fascial closure devices is that when the bond between the silicon pad and the surgical suture becomes weak, it becomes difficult to pull out the surgical suture, requiring additional work

[0015] Additionally, during the process of threading surgical sutures on the needle, the surgeon or nurse may be injured by a needlestick or become infected

During the process of closing multiple puncture ports, the above-mentioned problems occur repeatedly, whereby the operation time may be very long
