Disposable purse-string forceps for laparoscope

Abstract

The invention relates to disposable purse-string forceps for a laparoscope, which are used for realizing manual purse suture in the abdominal cavity of a patient and overcome shortcomings that an instrument for a laparoscope which is used for realizing circumferential purse suture for surfaces of digestive tract tissues in the abdominal cavity of the patient cannot enter the pneumoperitoneum to operate in the prior art. The disposable purse-string forceps comprise forceps and an opening and closing driving mechanism which is connected with the forceps, the driving mechanism is disposed in a shell, the shell comprises a rod arranged at the front end and a holding portion connected with the rod, a push rod is disposed in the shell, the tail end of the push rod extends out of the shell, needle holes are arranged on two sides of the inside of the rod, needles penetrate into the needle holes, head ends of suture threads are detachably fixed on needle heads, and needle tail ends are connected with the push rod. The driving mechanism drives the forceps to open and close, the forceps can tightly clamp tissues after being closed, the needles with the suture threads are filled in the needleholes, and are driven by the push rod to penetrate into the tissues, then the suture threads are tied tightly by a tool, and accordingly suture is realized.

Description

technical field [0001] The invention belongs to the field of surgical instruments in medicine and hygiene, in particular to a laparoscopic disposable purse forceps for manually suturing purses in the abdominal cavity. Background technique [0002] Since Kitano et al. reported the first case of laparoscopic-assisted distal gastrectomy in 1994, laparoscopic radical gastrectomy for early gastric cancer has flourished in Japan and South Korea; subsequently, Uyama et al. reported laparoscopic D2 radical gastrectomy for advanced gastric cancer in 1999 . After more than 10 years of development, the technology of laparoscopic surgery for early gastric cancer has matured, and its short-term and long-term curative effect is comparable to that of open surgery. In China, due to the relatively low diagnosis rate of early gastric cancer, advanced gastric cancer accounts for a large proportion, mainly based on laparoscopic D2, D1+α or +β lymph node dissection, and its application has been...

Problems solved by technology

[0005] The invention solves the defect in the prior art that the instruments that perform circumferential purse-string suture on the surface of the digestive tract tissue in the abdominal cavity cannot enter the laparoscopic pneumoperitoneum for operation, and provides a method that enters the pneumoperitoneum through the laparoscopic working channel, and cooperates with laparoscopic pneumoperitoneum.
