Description
Technical Field
The utility model belongs to the technical field of medical instrument makes, a minimally invasive surgery apparatus that is used for percutaneous transhepatic bile duct or gall-bladder puncture to and carry out fistulous way expansion, specifically speaking are biliary tract puncture fistulous way expansion 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.
No matter the cholecystotomy is performed under a laparoscope, the biliary tract exploration calculus extraction needs to be performed under general anesthesia. For the elderly and high-risk patients who can not tolerate the general anesthesia risk and the patients who receive a plurality of laparotomy operations, percutaneous transhepatic cholecystectomy and bile duct puncture drainage can be adopted firstly, then the fistula tract is gradually expanded, and when the fistula tract is expanded to more than 16Fr, a choledochoscope can be placed through the fistula tract to enter the gallbladder and lithotript in the duct. Fistulous tract expansion comprises two modes, one is that the fistulous tract is expanded to the stereoplasm expansion pipe that uses different models in once operation, but this kind of mode still needs to be accomplished under the general anesthesia state, and complications such as hemorrhage, liver abscess, gall leak easily take place, and another kind is the biliary tract drainage tube of intermittent replacement thicker model, and this kind of mode need not the anesthesia. The currently used drainage tube for bile duct puncture or fistula expansion is a single loop tube, wherein the drainage tube of 7-10Fr leads the head end to be a loop by tightening a traction wire, thereby achieving the purpose of preventing the drainage tube from slipping. However, for the drainage tube of 12Fr or above, because the drainage tube is thick and the difficulty of loop-forming is high, the drainage tube is often designed into a straight tube and placed in the bile duct or gallbladder, the head end of the drainage tube cannot be a loop and is easy to shift, and the tapered head end is easy to damage the gallbladder and bile duct mucous membrane, even serious complications such as perforation and bleeding of the gallbladder and bile duct occur.
