Title:
ABLATION NEEDLE TUBE, MICROWAVE ABLATION NEEDLE, AND MICROWAVE ABLATION TREATMENT INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2021/142910
Kind Code:
A1
Abstract:
An ablation needle tube (11), a microwave ablation needle (1), and a microwave ablation treatment instrument, relating to the field of medical equipment. The ablation needle tube (11) has at least two channels isolated from each other, wherein the at least two channels comprise a first channel (111) and a second channel (112), the distal and proximal ends of the first channel (111) respectively penetrate the distal and proximal ends of the ablation needle tube (11), so that a radio frequency cable (13) passing through the first channel (111) can be electrically connected to a radiating antenna (12) disposed at the distal end of the ablation needle tube (11), the first channel (111) is configured to accommodate a cooling liquid (3) for cooling the ablation needle tube (11), and the distal and proximal ends of the second channel (112) respectively penetrate the distal and proximal ends of the ablation needle tube (11), so that a connecting cable (15) passing through the second channel (112) can be electrically connected to an auxiliary element disposed at the distal end of the ablation needle tube (11). The ablation needle tube (11) enables the radiating antenna (12) to work normally, and also enables the auxiliary element to work normally. The ablation needle tube (11) has diverse functions, and can assist in better implementation of minimally invasive surgery.
