Description

Novel biliary tract calculus removing net

Technical Field

The utility model relates to the field of medical equipment, concretely relates to novel biliary tract calculus removing net.

Background

The choledochoscope calculus-removing net basket is used for capturing and removing choledochoscope calculus under a choledochoscope, most hepatobiliary calculus needs surgical treatment, regional hepatobiliary calculus can be used for surgical excision of diseased liver, treatment of diffuse hepatobiliary calculus is relatively troublesome, the difficulty lies in that calculus cannot be removed through excision of liver, and choledochoscope calculus removal is needed. The mesh of the existing stone taking net is too large, and the stone taking net can not hold small stones easily, so that the small stones are left in the body of a patient, meanwhile, steel wires on the stone taking net are easy to deform, and the deformed stone taking net is more difficult.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned problem, designed a novel biliary tract and got stone net. This novel biliary tract calculus removing net is equipped with the handle, promotes the handle and can makes the seal wire remove along the net circle, makes the net circle strut, the size of fixed net circle. After the stones are held, the pull ring is pulled to collect the stone taking bag and the stones into the tube sheath, so that the stones can be taken out more conveniently, smaller stones can be held, and small stones are prevented from leaking out.

In order to solve the above technical problem and achieve the above technical effect, the present invention is implemented by the following technical contents:

the utility model provides a novel biliary tract calculus removing net which characterized by: the stone taking device comprises a net ring, a stone taking bag, a tube sheath, a guide wire, a connecting plate, a push rod, a central rod, a rivet, a handle, a pull ring and a rubber block, wherein the lower surface of the net ring is fixedly connected with the stone taking bag; the net ring right-hand member is equipped with well core rod, well core rod and net ring fixed connection, well core rod right-hand member is equipped with the pull ring, pull ring and well core rod fixed connection, well core rod top is equipped with the block rubber, block rubber and well core rod fixed connection, the push rod is located the top of block rubber.

Preferably, the net ring and the stone bag are made of polypropylene materials, and the guide wire is made of memory alloy materials.

The utility model has the advantages that: this novel biliary tract calculus removing net is equipped with the handle, promotes the handle and can makes the seal wire remove along the net circle, makes the net circle strut, the size of fixed net circle. After the stones are held, the pull ring is pulled to collect the stone taking bag and the stones into the tube sheath, so that the stones can be taken out more conveniently, smaller stones can be held, and small stones are prevented from leaking out.
