Loop-type bile and pancreatic juice drainage tube

Abstract

The invention discloses a loop-type bile and pancreatic juice drainage tube, which comprises a loop-type bile drainage tube and a pancreatic juice drainage tube, wherein the loop-type bile drainage tube comprises a straight tube and an elastic loop tube; the elastic loop tube is integrally of a cylindrical spiral line shape and is provided with an elastic loop tube head and an elastic loop tube tail; the pancreatic juice drainage tube comprises a drainage tube body and a drainage tube tail positioned on the lower end of the drainage tube body; the pancreatic juice drainage tube also comprises a second line, wherein one end of the second line is connected with the lower-end side wall of the drainage tube body, and the other end of the second line passes through the drainage tube tail to be connected with a coil or a metal ring. According to the loop-type bile and pancreatic juice drainage tube, the slippage probability of the loop-type bile drainage tube is lowered, and the loop-type bile and pancreatic juice drainage tube does not irradiate a bile duct mucous membrane, duodenal papilla, gastrointestinal mucosa and a throat mucous membrane; while the loop-type bile drainage tube is taken out, the pancreatic juice drainage tube can be simultaneously taken out so as to avoid a secondary ERCP (Endoscopic Retrograde Cholangiopancreatography) surgery and lower treatment cost and surgery risks; the loop-type bile and pancreatic juice drainage tube has a function that the pancreatic juice drainage tube can be prevented from inwards moving or separating.

Description

technical field [0001] The invention relates to a drainage tube, in particular to a loop type 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 Ex...

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
