Abstract

The invention discloses a stone removing instrument for hepatobiliary department. The stone removing instrument comprises a push-pull handle, a push-pull catheter, an injection handle, a sheathing canal, a net basket and an end cap, the sheathing canal is arranged at one end of the injection handle, the push-pull catheter sequentially penetrates through the injection handle and the sheathing canal to be connected with the push-pull handle and the net basket, the end cap is arranged at one end, far away from the sheath tube, of the mesh basket, the mesh basket is formed by winding a connecting tube and a plurality of mesh basket wires into a spindle shape, and the mesh basket can be deformed and partially or completely retracted into the sheath tube by pulling the push-pull handle. According to the present invention, the connecting pipe is used as a support, the mesh basket wires deform to sleeve the stones into the mesh basket when the stones are sleeved, and the problem that the stones are not easy to press into the mesh basket due to deformation of the mesh basket wires is solved.

Description

technical field [0001] The invention relates to the technical field of stone removal equipment, in particular to a stone removal equipment for hepatobiliary department. Background technique [0002] In the classification of surgical diseases in our country, biliary calculus has a high incidence rate, and the number of new patients reaches millions every year, and biliary calculus disease brings great suffering to patients. At present, there are two types of treatment methods. One is to remove stones through surgery. This method cuts the patient's bile duct and other tissues through surgery, and removes the stones after reaching the stone site. The surgical trauma is relatively large, and the patient's recovery period is long and the cost is high. Another method is to use endoscopic technology to reach the bile duct with a special endoscope, and then use devices such as balloons and baskets to remove the stones. This method has less trauma and quicker recovery for the patien...
