Net-like basket for stone removal under choledochoscope

Abstract

The invention provides a net-like basket for stone removal under a choledochoscope. The basket includes a stone-removal net-like basket body, grasping forceps and a microwave line; a net-like basket pipe sleeve of the stone-removal net-like basket body is internally provided with a grasping-forceps hole and a microwave line hole which are communicated with the front end of the net-like basket pipe sleeve; the two sides of the net-like basket pipe sleeve are connected with a grasping-forceps catheter and a microwave line catheter, an inner hole of the grasping-forceps catheter is communicated with the grasping-forceps hole in the net-like basket pipe sleeve, the forcep ends of the grasping forceps and the electric head end of the microwave line are arranged on the outer side of the net-like basket pipe sleeve, the other end of the grasping forceps stretches to the outer side of the grasping-forceps catheter through the grasping-forceps hole and the grasping-forceps catheter, and the other end of the microwave line stretches to the outer side of the microwave line catheter through the microwave line hole and the microwave line catheter. According to the net-like basket for stone removal under the choledochoscope, stone can be effectively broken, the stone or the broken stone is taken out, bile duct injury is avoided, and the operation time is saved. The defects of the prior art are overcome, and the invention belongs to the field of biliary tract stone removal.

Description

technical field [0001] The invention relates to a net basket for stone removal by choledochoscopy, which belongs to the field of stone removal by biliary tract. Background technique [0002] Currently, the choledochoscope stone removal net basket is used to capture and remove biliary stones under choledochoscope. Most of the hepatic bile duct stones need surgical treatment. Regional intrahepatic bile duct stones can be surgically removed from the diseased liver. For diffuse intrahepatic bile duct stones The treatment is relatively difficult. The difficulty lies in the fact that it is impossible to remove the stones by removing the liver, so it is necessary to use the choledochoscope to remove the stones. At present, when using the choledochoscope to remove the stones with the basket for intrahepatic bile duct stones, the large bile duct stones cannot be removed directly with the basket , you need to crush the stone first. When crushing stones, it is necessary to insert the ...

AI Technical Summary

Problems solved by technology

If the lithotripsy effect is not satisfactory and the stone cannot be removed, it is necessary to repeat the above operation, which is time-consuming and laborious

At the same time, the existing technology cannot fix the stones when microwave lithotripsy is performed. When the microwave lithotripsy is performed, the stones move, and the microwave probe may interfere with the bile duct wall, causing damage and bleeding of the bile duct wall. Therefore, the existing choledochoscope The stone basket is still not perfect
