AI Technical Summary

Technical Problem

Existing gynecological tumor sampling devices have difficulty achieving uniform closure of multiple needle tracts during puncture, and the operation is complex and inefficient, increasing the risk of tumor cell spread.

Method used

A gynecological tumor sampling device was designed, comprising a puncture cannula, a sampling mechanism, a sealing mechanism, and an auxiliary mechanism. The device achieves automatic closure of the needle path through the sealing element of the puncture needle core, and automatically loads the sealing element through the auxiliary mechanism, thus simplifying the operation process.

Benefits of technology

This method achieves uniform closure of multiple segments of the puncture needle tract, reducing the risk of tumor cell spread and improving the convenience and efficiency of the operation.

Abstract

The invention discloses a gynecological tumor sampling device, relates to the field of medical diagnosis instruments, and solves the problems that a puncture needle passage is difficult to be sealed in multiple sections when the existing gynecological tumor sampling device is used, and the whole operation equipment is not convenient and efficient enough to use, the gynecological tumor sampling device comprises a puncture cannula, a device box, a puncture needle core, a sampling mechanism, a sealing mechanism and an auxiliary mechanism, according to the tumor sampling device, during puncture, puncture can be conducted through the puncture needle head, the puncture cannula is guided to the needed position, tumor sampling operation is conducted through the sampling mechanism, and when the puncture cannula needs to be pulled out, the puncture needle head is taken down; the sealing function is achieved by sequentially outputting the multiple sets of sealing pieces in the puncture needle core into the puncture needle passage, the puncture needle head is disassembled and assembled through the auxiliary mechanism, automatic filling operation of the sealing pieces can be completed, and the device is simple in structure, efficient in operation, high in internal structural strength and more stable and convenient to use.
