AI Technical Summary

Technical Problem

Existing rapid fragmentation baskets are prone to breaking when faced with large and hard stones. Furthermore, the sharp edges of the fragmented stones may scratch the patient's tissue, resulting in incomplete stone removal or increased harm to the patient.

Method used

An auxiliary stone-breaking device was designed, comprising an operating handle, a sheath, a basket, a net rope, a connector, a breaking blade, and an operating component. By pulling the net rope, the connector and the breaking blade are rotated to assist in breaking the stones. The connector reduces the gaps in the basket to increase the coverage area and reduce the risk of scratches.

Benefits of technology

It improves the ability to break up stones, ensures efficient stone removal, reduces the probability of patients being scratched by the stone edges, simplifies surgical procedures, and improves safety.

Abstract

The invention relates to the technical field of medical equipment, in particular to an auxiliary stone breaking device which comprises an operating handle and a sheath tube arranged at one end of the operating handle and further comprises a basket net arranged at one end of the sheath tube. The net rope is arranged in the sheath tube, and the two ends of the net rope extend out of the two ends of the sheath tube respectively; the net rope is repeatedly pulled and pushed to drive the crushing cutter to rotate in a reciprocating mode through the connecting piece, so that the crushing cutter is used for assisting in crushing stones, the stone crushing capacity of the stone-taking basket net is effectively improved, efficient taking and using of the stones are guaranteed, meanwhile, the connecting piece is used for driving gaps of the basket net to be shrunk, and the wrapping area of the stone-taking basket net is increased; therefore, the probability that the stone edge scratches the human body is reduced.
