Novel array microwave ablation needle

Abstract

The invention provides a novel array microwave ablation needle, which comprises an ablation needle pipe and a handle; the tail end of the ablation needle pipe is connected with the handle. The novel array microwave ablation needle further comprises array ablation needles, a fine pipe, an array control device and a push device; the fine pipe is arranged in the middle part of the inner cavity of the ablation needle pipe, and the tail end thereof crosses through a through hole of the handle; the array ablation needle is arranged in the inner cavity of the ablation needle pipe, and the array ablation needle comprises at least two ablation needles; the ablation needles are evenly distributed on the periphery direction of outside of the fine pipe, and the front end of the array control device is connected to the tail ends of the ablation needles while the back end thereof is connected with the push device. The novel array microwave ablation needle has the advantages of accurately controlling the ablation scale, not repeated preformation of interposition and ablation to cancer cells with big area, greatly improving the ablation efficiency, greatly reducing the pain of patients, greatly removing disease, and remaining health tissues; besides, the needle can clean the wound of focus, absorb impurities after ablation, so as to accelerate heeling and reduce the bacterial infection; furthermore, the novel array microwave ablation needle can ablate the burning wound to epidermis of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel array microwave ablation needle. Background technique [0002] The microwave ablation needle is a minimally invasive puncture needle for the treatment of solid tumors guided by ultrasound. The curative effect of the new generation of microwave ablation needle has reached the level of imported argon-helium knife and radio frequency, and it has the advantages of safety and light postoperative burden. Its characteristics are: direct puncture, simple surgical operation; minimally invasive operation, less damage; can completely solve the problem of microwave rod temperature, through patented technology, the rod temperature can be lower than 50 ℃; the coagulation range of a single needle in vivo can reach 4cm-5cm, in a regular circle Shape, no tailing phenomenon; less pain for the patient during the operation; various types of ablation needles can precisely control the...

AI Technical Summary

Problems solved by technology

[0003] At present, the technical difficulties in the use and development of existing microwave ablation needles are as follows: 1. Most ablation needles have only one needle, and the shape of the needle is fixed. Adjust the shape of the ablation needle according to the shape and size of different tumors; 2. After the ablation needle ablation, it is difficult to disinfect the lesion wound in time; 3. When the ablation needle is taken out, it is easy to touch the patient's skin, causing secondary damage
