Degradable stapler for constructing bile-pancreatic fluid bypass port

Abstract

A degradable stapler for constructing a bile-pancreatic fluid bypass port comprises two interlocking ball rings, a link guide cylinder is vertically arranged on the edge of the ball ring with small relative diameter, the connecting guide barrel is composed of a plurality of uniformly spaced first arc pieces and a second arc piece, the outer diameter of the first circular arc piece is smaller thanthe inner diameter of the second circular arc piece, the first circular arc piece is provided with a buckle body, the inner side of the second circular arc piece is provided with a positioning card body and a closing card body matched with the buckle body of another ball ring, and the positioning card body is positioned above the closing card body; the closed card body is a two-stage closed card body, and the buckle body is buckled with the two-stage closed card body twice. By using the invention, the digestive tract with different wall thicknesses of different patients can be adapted, and thehealing requirements of the bile-pancreatic bypass orifice in an alkaline environment can be met.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a degradable stapler for constructing a bile-pancreatic juice diversion port. Background technique [0002] Gastrointestinal anastomosis reconstruction is one of the most common surgical operations, clinically, it is nothing more than manual suture, stapler stapler and biodegradable stapler. [0003] The method of manual suturing is time-consuming, cannot be standardized, and has some defects such as damage to the surviving intestinal wall tissue during suturing, causing bleeding, scarring of the anastomotic stoma after healing, and a high probability of anastomotic leakage. [0004] The use of titanium nail stapler for anastomotic anastomosis has the advantages of simple operation, rapid suturing, and fewer complications. Moreover, this type of instrument can shorten the operation time and improve the operation efficiency. However, the titanium nail of this type of stapler will b...

AI Technical Summary

Problems solved by technology

However, this stapler cannot meet the individual differences of patients, especially for the digestive tract with too thick wall, it will not be fastened, and for the digestive tract with thin wall, the phenomenon of incomplete closure will occur after fastening; secondly, for the digestive tract with pH>7.0 There is an inconsistency between the degradation rate of the anastomotic ring and the healing time of the anastomosis in the digestive tract system under alkaline environment
