Multi-purpose nasal biliary drainage tube

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and in particular relates to a multi-purpose nasal biliary drainage tube. The multi-purpose nasal biliary drainage tube comprises a drainage tube section I, a drainage tube section II, a drainage tube section III, a drainage tube section IV, a drainage tube section V and a drainage tube section VI, wherein the drainage tube section I is of straight line type, the drainage tube section II is spiral, and a channel I in the drainage tube section II communicates with the drainage tube section I; the center of the drainage tube section III is bent, the formed angle alpha is 30-45 degrees, a channel III in the drainage tube section III communicates with the channel I, and a channel IV in the drainage tube sectionIII communicates with a channel II; the center of the drainage tube section IV is bent, the formed angle beta is 60-90 degrees, and the drainage tube section IV communicates with the channel III; thecenter of the drainage tube section V is bent, the formed angle gamma is 60-120 degrees, and a channel V of the drainage tube section V communicates with the channel III; the drainage tube section VIis of straight line type, a channel VII in the drainage tube section VI communicates with the channel V, and a channel VIII in the drainage tube section VI communicates with the channel VI. The multi-purpose nasal biliary drainage tube can be widely popularized and applied in the fields including endoscope treatment for the diseases including hepatobiliary and pancreatic diseases.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a multifunctional nasobiliary drainage tube. Background technique [0002] 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 common bile duct stones, acute obstructive suppurative cholangitis, bile duct injury , biliary stricture, biliary complications after liver transplantation, etc. Compared with traditional laparotomy, this technique has the advantages of less trauma, high safety factor, and faster recovery. After ERCP treatment, external nasobiliary drainage tubes are routinely placed to drain infectious bile, bile sludge, and gravel, which can reduce the incidence of postoperative cholangitis and the recurrence rate of choledocholithiasis. [0003] At present, the nasal and biliary drain...

AI Technical Summary

Problems solved by technology

This drainage tube has the following disadvantages: 1. The head end of the drainage tube is naturally looped, and its fixing force is small, and the drainage tube is prone to prolapse; Injury can even induce complications such as acute cholangitis, acute pancreatitis, and upper gastrointestinal bleeding; 3. It only has the function of bile drainage, and the continuous loss of bile will lead to the neutralization of bile and comprehensive gastric acid, killing bacteria, digesting fat, The function of stimulating intestinal peristalsis is weakened, and complications such as metabolic acidosis and malnutrition appear; Intestine, causing the contrast agent to flow back into the intrahepatic bile duct, causing bile blood reflux, leading to acute cholangitis, and at the same time, the middle and lower parts of the common bile duct are poorly developed
