Abstract

The invention discloses a hepatobiliary stone removal device, comprising: a push-pull handle, a push-pull catheter, an injection handle, a sheath tube, a mesh basket and an end cap, the sheath tube is arranged at one end of the injection handle, and the push-pull catheter passes through the The injection handle and the sheath are connected to the push-pull handle and the basket, the end cap is arranged on the end of the basket away from the sheath, and the basket is wound by a connecting pipe and a plurality of basket wires It is spindle-shaped, and the mesh basket can be deformed and partially or completely retracted into the sheath by pulling the push-pull handle. In the present invention, the connecting pipe is used as a support, and the mesh basket wire is deformed to insert the stone into the mesh basket when the calculus is taken out, thereby solving the problem that the deformation of the mesh basket wire makes it difficult to press the stone into the mesh basket.

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...
