CALCULUS REMOVING MESH BASKET AND DOUBLE-CAVITY END CAP FOR CALCULUS REMOVING MESH BASKET

摘要

Disclosed is a stone extraction basket, comprising a mesh basket (1), an outer tube (2) and an operation portion (10), wherein the mesh basket (1) is connected to the operation portion (10), and the operation portion (10) can control the mesh basket (1) to move; a proximal end of the outer tube (2) is connected to the operation portion (10), the outer tube axially extends from the proximal end to a distal end, and the distal end of the outer tube (2) is provided with a double lumen end cap (5); and a guide wire (4) passing through one lumen channel (B7) of the double lumen end cap (5), and the mesh basket (1) passes through the other lumen channel (A6) of the double lumen end cap (5). The stone extraction basket solves the existing technical problem of the mesh basket being hampered from removing a calculus and being withdrawn from the biliary tract because the guide wire is driven by the end cap at the distal end of the mesh basket.
