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 ...
