Problems solved by technology

[0005] The above-mentioned technical solution has the following disadvantages. When the gallbladder and common bile duct are complicated with stones, one operation cannot solve the problem of removing stones by crushing the stones. In addition, the stone removal channel is not smooth, and the stone removal basket will touch th

Abstract

The invention discloses a fishing two-endoscope one-wire combined minimal invasive liver protection internal and external bile duct calculus crushing and removing method, and relates to medical instruments. The method is used for solving the problems that an existing calculus removing mesh basket touches the inner wall of a bile duct, pain, a wound and bleeding are easily caused in an operative process, and bile duct calculus removal, irrigation, radiography and dilation cannot be integrated. The method comprises a calculus removing mesh basket, a choledochoscope and a laparoscope, the calculus removing mesh basket comprises a catheter, a hollow guide head and mesh baskets, the guide head is positioned at the left end of the catheter, the mesh baskets are positioned on the guide head and include at least two first mesh baskets and at least two second mesh baskets, the catheter comprises an outer tube, a sliding tube, an inner tube and a sliding connector which are arranged from outside to inside, the sliding connector comprises a first terminal, a second terminal and a connecting shaft, and the connecting shaft is used for connecting the first terminal with the second terminal. By the design of the closed mesh baskets, the calculus removing mesh basket cannot touch the inner wall of the bile duct, pain, the wound and bleeding are avoided in the operative process, and bile duct calculus removal, irrigation, radiography and dilation can be integrated.

Description

Technical field [0001] The invention relates to a medical device, specifically, a fishing method, two mirrors and one wire combined with a minimally invasive liver-protecting bile duct stone lithotripsy surgery. Background technique [0002] The causes of intra- and extrahepatic bile duct stones are related to the bacterial infection, parasitic infection and bile retention of the biliary tract. In addition, the mucin, acid mucopolysaccharide, immunoglobulin and other macromolecular substances in the bile, inflammatory exudates, shed epithelial cells, bacteria, parasites, metal ions in the bile, etc., all participate in the formation of stones. According to the different course and pathology, the clinical manifestations of intrahepatic bile duct stone disease can be various, from the early stage without obvious clinical symptoms to the stones in a certain segment of the intrahepatic bile duct, to the later period, the intrahepatic bile duct system and even complicated Late cases ...
