Posterolateral stapling instrument for tubular esophagus and stomach anastomosis

Abstract

A stapling instrument for the posterolateral side of the anastomosis of the tubular esophagus and the stomach, which includes a tube extending into the front end of the tube, a stapling part capable of forming a "mouth"-shaped suture structure with an opening, and an operating part extending into the rear end of the tube; The stapling part includes the nail cartridge integrally connected with the extension tube, the pressing structure for pressing the nails out of the magazine, and the moving block that drives the pressing structure to move down and is moved by the operation of the operating part; the reciprocating motion of the moving block drives the pressing structure to repeat Pressing down and returning, the longitudinal direction of the staple cartridge is consistent with the longitudinal direction of the insertion tube, the two sides of the front end of the staple cartridge are provided with blocking plates to block the staples, and the inner side of the blocking plate is provided with an opening for the staples to move down and out of the staple cartridge; the insertion tube Corresponding to the front section of the rear wall of the opening and the lower part of the staple cartridge, a gap is set; a "T"-shaped support is set in the middle of the front of the staple cartridge, and the "T"-shaped support includes a beam one and a longitudinal support beam; The transverse bar of the T-shaped support is bent to form a "mouth"-shaped suture structure to suture the tissue.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for digestive endoscopic surgery, in particular to a post-lateral stapling instrument for the anastomosis of the tube-shaped esophagus and the stomach. Background technique [0002] Esophagogastric anastomosis, usually after the esophagus and stomach are cut and sutured on the outside, a suture machine is used to suture the inside of the esophagus, but only the inner circle of anastomosis is sutured, and the fluid in the esophagus before it is completely healed It will flow out at the needle eye of the suture, which will cause anastomotic leakage. Usually, in order to avoid this phenomenon, it is necessary to manually suture the periphery. When suturing, the surgeon needs to complete the suture under laparoscope. [0003] The problem of the prior art is: since the sutured position is close to the heart and needs to be sutured in a circle, the heart needs to be lifted up slightly during...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the technical problems in the prior art that the suturing of the outside of the esophagus and the stomach is highly risky, has high requirements for doctors to operate, and there is no effective instrument to quickly complete the operation, and provides a tubular esophagus and stomach outside stapling instrument after anastomosis
