AI Technical Summary

Technical Problem

In the prior art, coaxial needle and radio frequency needle are two different sales units, and doctors need to match specifications based on experience, resulting in the gap between the coaxial needle and radio frequency needle being too loose or too tight, causing patient damage or damage to the insulation layer of the radio frequency needle, increasing the risk of safety accidents.

Method used

A coaxial biopsy radiofrequency ablation needle is designed. By setting the inner needle rod and the outer needle tube as coaxial and using threaded connections, the stable installation of the inner needle rod and the outer needle tube is reduced, reducing the risk of surgical selection time and movement deviation.

Benefits of technology

Through coaxial design and threaded connection, the operation selection time is reduced, the installation stability is improved, the operation safety is increased, the risk of discomfort of optional coaxial needles is reduced, and the risk of intraoperative movement deviation is reduced.

Abstract

The invention belongs to the technical field of tumor radiofrequency ablation, and particularly relates to a coaxial biopsy radiofrequency ablation needle which comprises a handle, a cavity is formed in the handle, the biopsy radiofrequency ablation needle further comprises an outer needle tube, and the right end of the outer needle tube penetrates through the cavity and is fixedly installed on the inner wall of the cavity; the insulating sleeve is fixedly installed on the inner wall of the outer needle tube, and a water inlet cavity and a water outlet cavity are formed in the insulating sleeve; the right end of the inner needle rod penetrates through the insulating sleeve and is in contact with the interior of the insulating sleeve; the inner needle rod and the outer needle tube are arranged to be coaxial, a coaxial needle does not need to be selected according to a radio frequency needle, the operation selection time is shortened, ablation is carried out only after one-step puncture in place, the radio frequency needle does not need to be matched after coaxial puncture, the risk of movement deviation in the operation is reduced, and the operation safety is improved; and the risk caused by the discomfort of selecting and matching the coaxial needle is reduced.
