Novel biliary and intestinal anastomosis stent drainage device

Abstract

The invention discloses a novel biliary and intestinal anastomosis stent drainage device, relates to the technical field of medical suction instruments, and aims to solve the technical problems of difficult surgery operation, many surgical traumas of patients, poor postoperative recovery experience, and easy confusion of multiple bile duct drainage of a biliary and intestinal stent tube drainage mode in the prior art. The device comprises a main drainage tube, a drainage bottle and a plurality of stent tubes; the liquid inlet end of the main drainage tube extends into a human body, and the liquid outlet end of the main drainage tube is connected to the inlet of the drainage bottle; and each stent tube comprises a liquid inlet part, a liquid outlet part and a stent tube body, the stent tubebody is embedded in the wall of the main drainage tube, each stent tube does not communicate with the main drainage tube, the liquid inlet part extends into the human body through the main drainage tube, and the liquid outlet part is connected to the inlet of the drainage bottle.

Description

technical field [0001] The invention relates to the technical field of medical suction instruments, in particular to a novel biliary-enteric anastomosis stent drainage device. Background technique [0002] Complex high cholangiojejunostomy is a difficult operation in the field of hepatobiliary surgery. It is mainly suitable for bile duct reconstruction after hilar cholangiocarcinoma, intrahepatic cholangiocarcinoma and other lesions are resected, as well as for the treatment of complicated intrahepatic bile duct stones combined with bile duct stricture and damaged bile duct stricture. . The difficulty of the operation is that multiple bile ducts need to be shaped or anastomosed separately to complete the high bile duct-jejunum anastomosis. Due to the slender diameter and thin wall of the high bile duct, delicate anastomotic techniques are required. Even if the anastomosis is satisfactory, the incidence of postoperative biliary anastomosis leakage is still high. If the post...
