Problems solved by technology

First of all, the existing cholangioenterostomy uses interrupted suture or continuous suture to complete the anastomosis. Due to the fixed position of the bile duct and the deep operation area, it is difficult to implement; secondly, the incidence of bile leakage after anastomosis is high, especially in the case of When the diameter of the bile duct is small, and the anastomotic stricture is prone to occur after anastomosis

Embodiment Construction

[0010] Refer to attached figure 1 , 2 :

[0011] A support tube for biliary-enteric anastomosis, comprising a through-tube 1 made of silica gel, said through-tube 1 comprising an anastomotic end 11 for anastomosis of bile duct and small intestine and a drainage end 12 communicating with the outside of the body, said through-tube at the anastomotic end The outer surface has a first protruding ring 21 for binding the bile duct and a second protruding ring 22 for binding the small intestine, and the part of the through tube 1 located in the small intestine is provided with a side hole 3 . The anastomotic end 11 of the through tube 1 is connected with a fork tube 4 corresponding to the bifurcation structure of the bile duct.

[0012] During the anastomosis, purse-string sutures are first made on the broken end of the bile duct and the intestinal wall, and the broken end of the bile duct and the intestinal wall are fixed between the two protruding rings of the support tube throug...

Abstract

A biliary-enteric anastomosis support tube, includes a siphunculus made from silicagel, the siphunculus includes an anastomosis end for anastomosing bile duct with small intestine and a drainage end for communication with vitro. The external surface of the siphunculus in the anastomosis end is provided with a first prominent ring for banding the bile duct and a second prominent ring for banding the small intestine, part of the siphunculus lies in the small intestine is provided with a side opening, the anastomosis end of the siphunculus is connected with a breeches pipe corresponding to bifurcation structure of the bile duct. The invention is provided with advantages of simplification of the biliary-enteric anastomosis, shorting anastomosis time, reducing postoperative complications.

Description

(1) Technical field [0001] The invention relates to a support tube for biliary-enterostomy, which can simplify biliary-enterostomy and improve the safety of biliary-enterostomy. (2) Technical background [0002] Biliary-enteric anastomosis is a common operation in abdominal surgery, but there are still many deficiencies in this anastomotic technique. First of all, the existing cholangioenterostomy uses interrupted suture or continuous suture to complete the anastomosis. Due to the fixed position of the bile duct and the deep operation area, it is difficult to implement; secondly, the incidence of bile leakage after anastomosis is high, especially in the case of When the diameter of the bile duct is small, and the anastomotic stricture is prone to occur after anastomosis. (3) Contents of the invention [0003] The present invention aims to solve the above-mentioned shortcomings of the existing biliary-enterostomy, and the present invention provides a support tube that can ...
