Abstract

The invention relates to a directional melting needle for the interventional operation. The melting needle comprises a handle, a needle body and a directional assembly arranged on the handle; the directional assembly comprises a gyroscope used for sensing direction changes, a data processing module used for calculating direction information, a display module used for displaying direction information and a periphery module providing power to the directional assembly. Through cooperation among all modules in the directional assembly, the posture data of a puncture needle is displayed on a liquidcrystal screen in real time, an operator can visually acquire information and timely make adjustment, the directional purpose in the operation process can be conveniently achieved, and accurate control is facilitated; the directional melting needle solves the problem in the prior art that the puncturing process of the melting needle lacks the directional operation and has positive technique significance.

Description

technical field [0001] The invention relates to a directional ablation needle for interventional operations, belonging to the technical field of medical devices. Background technique [0002] With the development of medical technology, the clinical application of medical imaging has become more and more extensive and in-depth; for example, the application in the field of minimally invasive interventional tumor surgery provides an excellent solution for tumor treatment. In minimally invasive interventional therapy, one medical method is interventional ablation. The principle is to use minimally invasive surgery to establish a surgical channel, then insert the ablation needle into the tumor, and ablate the tumor through the transmitter on the top of the ablation needle. [0003] In the prior art, after obtaining tumor information through imaging means, it is possible to design a surgical plan and obtain a theoretical path for the ablation needle to penetrate into the tumor; I...
