Multistage fistulous tract expanding type puncturing drainage tube having balloon

Abstract

The invention provides a multistage fistulous tract expanding type puncturing drainage tube having a balloon. The multistage fistulous tract expanding type puncturing drainage tube having a balloon comprises a drainage tube and an inner core, wherein the drainage tube comprises a head, a balloon part, a body part and a tail; a passage I is arranged in the head; the balloon part comprises a drainage tube I in which a passage II and a passage III are arranged, and a head end balloon; a passage IV, a passage V, a passage VI, a passage VII and a passage VIII are arranged on the body part; a balloon I, a balloon II and a balloon III which are telescopic, are in sleeving connection to the outer wall of the body part; a passage IX, a passage X, a passage XI, a passage XII and a passage XIII are arranged in the tail; a connector I, a connector II, a connector III and a connector IV are arranged on the tube wall of the tail, and a connector V is arranged at the middle part of a bottom end; thetail end of the inner core and the connector V are in cooperative connection; and the inner core is inserted in the passage in the connector V and runs through the passage I. According to the multistage fistulous tract expanding type puncturing drainage tube having a balloon disclosed by the invention, the fistulous tract expanding scope can be enlarged, the replacement number of times of the drainage tube is reduced, the course of diseases is shortened, and the manufacturing cost is low.

Description

technical field [0001] The present invention relates to the field of minimally invasive medical technology and surgical instrument technology, in particular, to a multi-stage fistula tract expansion type puncture drainage tube with a balloon, which is used for percutaneous transhepatic bile duct puncture and subsequent treatment of fistula tract expansion. Minimally invasive surgical instruments for biliary system diseases, or minimally invasive surgical instruments for dilating percutaneous transhepatic biliary puncture tracts to treat biliary system diseases. Background technique [0002] Gallbladder and extrahepatic bile duct stones are a common disease, which can induce acute and chronic cholecystitis, cholangitis, obstructive jaundice, biliary tract tumors and other complications. The traditional treatment for gallstones is open cholecystectomy and hepatic lobectomy. Today, with the development of laparoscopy and choledochoscopy, laparoscopic cholecystectomy and biliary...

AI Technical Summary

Problems solved by technology

There are two ways to dilate the fistula tract. One is to use different types of hard dilation tubes to expand the fistula tract in one operation. The other is intermittent replacement of thicker biliary drainage tubes. This method does not require anesthesia, but the interval between two operations is longer, resulting in longer treatment time for the disease

If the interval time is short or a thicker type of drainage tube is selected, it will not only increase the pain of the patient, but also increase the difficulty of tube placement
