Integrated bile-pancreatic drainage tube

Abstract

The invention discloses an integrated bile-pancreatic juice drainage tube, which includes a water bladder type bile external drainage tube and a pancreatic juice internal drainage tube. The water bladder type bile external drainage tube includes drainage tube section I, drainage tube section II and drainage tube section connected in sequence III, the outer wall of the drainage tube section II is sleeved with a balloon film; the pancreatic juice internal drainage tube includes a drainage tube body, a cap, and a tail of the drainage tube, and the end of the drainage tube section III that is far away from the drainage tube section II is connected to the The drain tube tails match. The present invention has strong tension, can prevent the prolapse of the water bladder type bile external drainage tube, is suitable for bile ducts of various diameters, has no damage to the bile duct mucosa, duodenal papilla and upper gastrointestinal mucosa, and is effective in preventing water The displacement of the cystic external bile drainage tube will not cause biliary obstruction, and the internal pancreatic juice drainage tube is connected with the water cystic bile external drainage tube through a thread, which can prevent the internal displacement or prolapse of the pancreatic juice internal drainage.

Description

technical field [0001] The invention relates to a drainage tube, in particular to an integrated bile and pancreatic juice 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 choledocholithiasis, bile duct injury, bile duct stricture, and liver transplantation. Posterior 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 ...

AI Technical Summary

Problems solved by technology

[0005] The head of the nasobiliary drainage tube currently used clinically can entangle itself in the bile duct, but the stimulation of the head of the drainage tube to the bile duct mucosa can lead to local mucosal reactive hyperplasia; during the extubation process, the head of the drainage tube can cause bile duct and Injury to the intestinal mucosa can even induce complications such as acute cholangitis, acute pancreatitis, and upper gastrointestinal bleeding; irritation of the throat by the drainage tube often leads to severe nausea and even vomiting in patients
