Abstract

The invention discloses a loop type bile external drainage tube, which comprises straight tubes connected in sequence, an elastic loop tube I and an elastic loop tube II, and the elastic loop tube I and the elastic loop tube II overall form an Archimedes curve shape, the side wall of the elastic loop tube I is provided with a through hole for accommodating the head of the elastic loop tube II, and the through hole is located in the plane where the Archimedes curve is located. the wire so that the head of the elastic haptic tube II enters the through hole. The present invention increases the tension of the elastic loop tube I on the bile duct wall when the thread is tightened, reducing the probability of slippage of the loop-type bile external drainage tube; No damage; in the process of pulling out the drainage tube, there is no stimulation to the bile duct mucosa, duodenal papilla, gastrointestinal mucosa and throat mucosa, and will not cause acute cholangitis, acute pancreas, upper gastrointestinal bleeding and other complications Symptoms; during the extubation process, the patient's reaction will also be greatly reduced.

Description

technical field [0001] The invention relates to a bile external drainage tube, in particular to a loop type bile external drainage tube. Background technique [0002] 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, liver transplantation, etc. 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 diverticulum, duodenal Excessive intesti...
