Y-shaped bile and pancreatic juice drainage tube with water bladder

Abstract

The invention discloses a Y-type bile and pancreatic juice drainage tube with a water bladder, which comprises a water bladder type bile external drainage tube and an internal pancreatic juice drainage tube. The water bladder type bile external drainage tube includes drainage tube section I, drainage tube section II and drainage tube section Tube section 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 and a cap I located at the upper end of the drainage tube body, the side of the drainage tube body The wall is connected with the side wall of the drainage tube section I through a connecting part. The present invention has the function of preventing the prolapse of the external drainage tube of the water bladder and preventing the displacement or prolapse of the internal drainage of pancreatic juice, and is suitable for bile ducts of various diameters, and is suitable for bile duct mucosa and duodenal papilla during insertion and removal. There is no damage to the upper gastrointestinal mucosa. While preventing the displacement of the water bladder external drainage tube, it will not cause biliary obstruction. When the water bladder external drainage tube is taken out, the pancreatic juice internal drainage tube can be removed at the same time.

Description

Technical field [0001] The invention relates to a drainage tube device, in particular to a Y-type bile pancreatic juice drainage tube with water bladder. Background technique [0002] At present, with the continuous development of endoscopic technology and the continuous improvement of its accessories, duodenoscope technology (ERCP) has become an important measure for the treatment of hepatobiliary and pancreatic diseases, including common bile duct stones, bile duct injury, bile duct stenosis, liver transplantation Post biliary complications and so on. Compared with traditional open surgery, this technique has the advantages of less trauma, higher safety factor, and faster recovery. Under direct observation, he can detect hepatobiliary and pancreatic diseases that cannot be detected by conventional hepatobiliary, spleen and pancreas CT, ultrasound, and magnetic resonance. At the same time, he can be treated, such as duodenal papillitis, nipple stenosis, paranipple diverticulum,...

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
