Abstract

The invention discloses a water bag type gall external drainage tube. The water bag type gall external drainage tube comprises a drainage tube section I, a drainage tube section II and a drainage tube section III which are communicated in sequence, wherein a ball bag thin film sleeves the outer wall of the drainage tube section II; the cross section of the ball bag thin film is in a plum blossom shape; the drainage tube section I is internally provided with a pipeline I communicated with the drainage tube section II and a pipeline II communicated with the ball bag thin film; the other end of the pipeline II is connected with a pipe by a cap and the other end of the pipe is connected with a three-way valve; the cap is provided with a cylindrical head part and a circular-platform-shaped tail part; the small end of the circular-platform-shaped tail part is fixedly connected with the cylindrical head part. The water bag type gall external drainage tube has higher tension and is prevented from being released; the water bag type gall external drainage tube is suitable for common bile ducts with different diameters; the water bag type gall external drainage tube has no damages to bile duct mucosa, duodenal papilla and upper gastrointestinal tract mucosa when being put in or taken out; the water bag type gall external drainage tube can be prevented from displacement and the obstruction of the biliary tract is not caused.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a water bladder type bile external drainage tube. Background technique [0002] At present, with the continuous development of endoscopic technology and the continuous improvement of its accessories, duodenoscopy (ERCP) has become an important measure for the treatment of hepatobiliary and pancreatic diseases, including common bile duct stones, bile duct injury, bile duct stricture, and liver transplantation. Postoperative biliary complications, etc. Compared with traditional laparotomy, this technique has the advantages of less trauma, high safety factor, and faster recovery. Under direct vision, it can detect hepatobiliary and pancreatic diseases that cannot be detected by conventional liver, gallbladder, spleen and pancreas CT, ultrasound and magnetic resonance examinations, and treat them at the same time, such as duodenal papillitis, papillary stenosis, parapapillary divertic...
