Bile and pancreatic juice drainage tube

Abstract

The invention discloses a bile and pancreatic juice drainage tube which comprises a loop type bile external drainage tube and a pancreatic juice internal drainage tube. The loop type bile external drainage tube comprises a straight tube, an elastic loop pipe I and an elastic loop pipe II which are connected in sequence, wherein the elastic loop pipe I and the elastic loop pipe II are in the shapes of Archimedean curves one the whole. The pancreatic juice internal drainage tube comprises a drainage tube body and a tube cap located at the upper end of the drainage tube body, and a line II is arranged on the drainage tube body and penetrates through the side wall of the straight tube and extends in a tube cavity of the straight tube. The bile and pancreatic juice drainage tube reduces the probability of slipping of the loop type bile external drainage tube, does not stimulate bile duct mucosae, duodenal papilla, gastrointestinal mucosae and throat mucosae, and has an effect of preventing the pancreatic juice internal drainage tube from dislocating or escaping.

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 Excessive in...

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
