Y-shaped bile pancreatic juice drainage tube

Abstract

The invention discloses a Y-shaped bile pancreatic juice drainage tube. The drainage tube comprises a loop type bile outer drainage tube body and a pancreatic juice inner drainage tube body. The loop type bile outer drainage tube body comprises a straight tube, an elastic loop tube I and an elastic loop tube II which are connected successively. The whole of the elastic loop tube I and the elastic loop tube II are in an Archimedes shape. The pancreatic juice inner drainage tube body comprises a drainage tube body and a tube cap arranged at the upper end of the drainage tube body. The side wall of the drainage tube body is connected with the side wall of the straight tube through a connection portion. By means of the drainage tube, the probability of slip of the loop type bile outer drainage tube body is reduced, bile duct mucosae, duodenal papilla, and gastrointestinal tract mucosae and pars laryngea pharyngis mucosae are all simulation-free. By means of the drainage tube, the pancreatic juice inner drainage tube body can be taken out while the loop type bile outer drainage tube body is taken out, the secondary ERCP operation is prevented, and the treatment cost and the operation risk are reduced.

Description

technical field [0001] The invention relates to a drainage tube, in particular to a Y-shaped drainage tube for bile and pancreatic juice. 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
