T-shaped dual-chamber balloon expanding drainage tube

Abstract

The invention relates to a T-shaped dual-chamber balloon expanding drainage tube, and is used for effectively solving the problems that after bile duct end to end anastomosis, retraction of anastomotic stoma scar leads to stenosis of long-term bile duct anastomotic stoma and repeated attack of cholangitis and the expansion effect of the existing equipment can not be adjusted. The technical scheme is as follows: the T-shaped dual-chamber balloon expanding drainage tube comprises a long conduit and a short conduit; one end of the long conduit is vertically connected with the middle part of the short conduit to form a T shape and the conduit chambers are communicated mutually; conduit walls of two ends of the short conduit are painted with developing material marks respectively; the short conduit is covered with a balloon; an gas injection channel and a drainage channel are arranged in the long conduit to form a dual-chamber structure; one end of the gas injection channel is connected with the balloon at the short conduit and the other end is separated from the long conduit and is upward; an air inlet is arranged at the end part; and the drainage channel is communicated with the inner chamber of the short conduit. The T-shaped dual-chamber balloon expanding drainage tube has the advantages of simple, novel and unique structure and progressive and adjustable expansion effect, thus pains of patient are greatly alleviated. In addition, the manufacturing cost is low, the use is convenient and the economic and social benefits are great.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a T-shaped double-chamber balloon expansion drainage tube. Background technique [0002] After the confluence of the left and right hepatic ducts, the common hepatic duct is formed, which descends from the right lower edge of the hepatoduodenal ligament and joins the cystic duct to form the common bile duct, descends on the right side of the proper hepatic artery and the right front of the portal vein, and enters the opening of the posterior inner wall behind the duodenum in the duodenal papilla. The adult common bile duct is 6-8mm in diameter, 70-90mm in length, and the common hepatic duct is about 5mm in diameter. The confluence of the common hepatic duct and the cystic duct is often easily injured during cholecystectomy. [0003] In recent years, with the extensive development of biliary tract surgery and the popularization of laparoscopy, the incidence of bile duct injury te...
