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

[0009] With reference to accompanying drawing, the present invention is further described:

[0010] The support tube for biliary-enteric anastomosis includes a through-tube 1 made of silica gel. The through-tube 1 includes an anastomotic end 11 for anastomosis of the bile duct and the small intestine and a drainage end 12 connected to the outside of the body. The outer surface of the anastomotic end of the through-tube is There is 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 passage tube 1 located in the small intestine has a hole 3 on one side.

[0011] The technical concept of the present invention is: during anastomosis, purse-string sutures are firstly performed on the broken end of the bile duct and the intestinal wall, and through the purse-string suture, the broken end of the bile duct and the intestinal wall are fixed between the two protruding rings of the support tube, so that...

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 invention is provided with advantages of simple anastomosis method; separating anastomotic stoma from bile and intestinal contents effectively that is helpful to growth of anastomotic stoma; preventing postoperative anastomotic stenosis effevtively and ensuring bile discharge fluently; avoiding bile loss; reducing backflow of the intestinal contents into bile duct.

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 ...
