Description

Biliary tract mirror flushing drainage tube

Technical Field

The utility model belongs to the technical field of medical instrument makes, a minimal access surgery apparatus for driving small calculus and gall mud in liver is related to, specifically speaking is a choledochoscope washes drainage tube.

Background

Calculus of gallbladder and intrahepatic and extrahepatic bile ducts is a common disease and can induce complications such as acute and chronic cholecystitis, cholangitis, obstructive jaundice, biliary tumors and the like. The traditional treatment modes of gallstones are abdominal cholecystectomy and liver lobe resection, and the laparoscopic and choledochoscope technology is increasingly developed nowadays, and the cholecystotomy and the biliary tract exploration lithotomy under the laparoscope become important means for treating the gallstones.

The cholecystotomy and the biliary tract exploration calculus removal under the laparoscope need to be completed under general anesthesia, and the calculus removal tool is the most commonly used choledochoscope except for the traditional calculus removal forceps. If the operation time is long and the calculus of the intrahepatic bile duct cannot be completely removed, in order to reduce the incidence rate of the postoperative biliary leakage, a T tube is kept in the operation, and a choledochoscope is used for performing a choledochoscope calculus removal operation through the T tube fistulous tract for 6-8 weeks.

The stones with the size of the peanuts can be directly taken out by using a stone-taking basket; stones with the diameter of less than 5mm are difficult to be taken by the basket, and are mostly taken by using an absorber, but the stones absorbed by the absorber are less, and the stones repeatedly enter and exit from a fistula tract or a common bile duct, so that acute cholangitis is easy to occur to bile duct edema, or drainage tube placement is difficult to achieve due to fistula tract edema; for the calculus with the length of more than 1cm, the calculus is difficult to directly take out, microelectrodes and electrohydraulic calculus breaking are mostly carried out, then the calculus broken stone and the biliary mud are cleaned, and because the choledochoscope clamp channel is thin, the choledochoscope clamp channel is easy to block by the calculus and the biliary mud, the operation time is prolonged, and the calculus residue is easy to cause.
