bile-pancreatic drainage tube

Abstract

The invention discloses a bile-pancreatic juice drainage tube, which includes a loop-type bile external drainage tube and a pancreatic juice internal drainage tube. The loop-type bile external drainage tube includes straight tubes connected in sequence, an elastic loop tube I and an elastic loop tube II. The elastic loop tube I and the elastic loop tube II are in the shape of an Archimedes curve as a whole, and the pancreatic juice internal drainage tube includes a drainage tube body and a cap located at the upper end of the drainage tube body, and the drainage tube The tube body is provided with a line II, and the line II passes through the side wall of the straight tube and enters into the lumen of the straight tube. The invention reduces the slipping probability of the loop-type bile external drainage tube, has no stimulation to bile duct mucous membrane, duodenal papilla, gastrointestinal tract mucous membrane and throat mucous membrane, and has the effect of preventing displacement or prolapse of the pancreatic juice internal drainage tube.

Description

technical field [0001] The invention relates to a drainage tube, in particular to a 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 Intestinal p...

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
