Problems solved by technology

[0003] Traditional cystic cancer can only be treated by surgery or injection of chemotherapy drugs. Surgery can only be implemented in a small number of cases due to limited conditions. Injection of chemotherapy drugs is generally possible due to the presence of internal multi-compartment structures in cystic tumors. , the curative effect of the drug is not good, and there are many residues

Abstract

The invention relates to a microwave ablation antenna used for cystic tumor ablation therapy. The microwave ablation antenna comprises an insulation stabs head, a pole core, a coaxial cable, a water division pipe, a water plugging shaft, an inner pipe which sleeves the water division pipe and an outer pipe which sleeves the inner pipe, the front ends of the inner pipe and the outer pipe are arranged on a boss of the rear end of the insulation stabs head in a sleeved mode, a side hole is formed in the front portion of the outer pipe, a capillary tube is fixedly arranged between the inner pipe and the outer pipe, the head of the capillary tube extends near the side hole, the capillary tube is suitable for special injection and suction of a cystic tumor, a water inlet way is formed in the clearance between the water division pipe and the coaxial cable, a water outlet way is formed in the clearance between the water division pipe and the inner pipe, and cooling is effectively conducted on the antenna by using circulating cooling water.

Description

technical field [0001] The invention relates to a microwave needle used for the ablation treatment of cystic cancer tumors, and belongs to the technical field of microwave ablation needles. Background technique [0002] With the advancement of modern technology and oncology, domestic microwave tumor ablation technology has made breakthroughs in the past ten years. Microwave tumor ablation is to use microwave energy to act on tissues to produce thermal effects. Within a few minutes to tens of minutes, the central temperature of the thermal field can reach above 100°C. Purpose of ablation therapy. Microwave tumor ablation is to insert a microwave ablation needle into the lesion of human tissue, and the front end continuously emits microwave energy to perform the operation. Because of its high efficiency, small wound, and controllable depth and range of effect on the tissue, it is suitable for Ablation of solid tumors throughout the body. [0003] Traditional cystic cancer c...
