Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] see figure 1 , 2. The present invention includes a conical head 1 and a conical seat 4 connected thereto. Said conical head 1 is magnetic, has a conical structure with a thin top, slightly enlarged middle and upper parts, and the shape and structure of the conical head 1 is easy to insert The expansion part of the bile duct can play a fixed role. There is a through hole 3 on the cone head 1. The cone head 1 communicates with one end of the cylindrical catheter 2 through the through hole 3. The cone seat 4 is magnetic and hollow. Cone, cone seat 4 can be set on the catheter 2, and the inner diameter of the cone seat 4 is slightly larger than the outer diameter of the catheter 2, the lower end of the cone seat 4 is connected with the drainage tube, easy to pull out with the drainage tube, when the magnetic seat 4 passes through After the catheter 2 and ...

Abstract

A gall-intestine anastomosing scaffold is composed of a magnetic conic head with a through hole, a magnetic hollow conic seat, and a cylindrical tube connected between said conic head and conic seat via their internal holes. It features its magnetic anastomosis.

Description

technical field [0001] The invention relates to a surgical anastomosis bracket, in particular to a biliary-intestinal anastomosis bracket which can perform seamless anastomosis of bile duct and small intestine and functions as a bile duct bracket. It is also suitable for end-to-end anastomosis of bile duct or cholangioenterostomy in liver transplantation. Background technique [0002] The traditional cholangioenterostomy is to suture the biliary tract and the small intestine manually with sutures. Because the caliber of the biliary tract and small intestine is very different, end-to-side anastomosis is often used for the anastomosis. The anastomosis is difficult and requires high technical requirements. The incidence rate of the anastomosis is high, and the presence of anastomotic sutures can lead to mucosal erosion and tissue inflammation and edema, enhance the stimulation of bile to scar tissue, promote scar hyperplasia, and easily form anastomotic stenosis. Most of the a...
