Abstract

The invention discloses a microwave ablation needle antenna with an infusion structure for curing cyst and belongs to microwave ablation antennas. The microwave ablation needle antenna comprises an antenna rod body and a handle. The antenna rod body is connected with the handle. A radiator is arranged at the front head of an inner portion of the antenna rod body. A needle radiator sleeve is arranged on the radiator and further arranged at the end of the antenna rod body. The radiator is connected with a radio frequency coaxial connector which is arranged at the tail end of the antenna rod body through a coaxial cable. A water inlet channel and a water outlet channel are further arranged in the antenna rod body and communicated with each other. An independent injection channel is arranged in the antenna rod body. At least one through hole is formed in the front end of the antenna rod body. The injection channel is communicated with the outside through the through hole. Through the injection channel in the antenna rod body, artificial irrigation fluid is injected to do auxiliary cleaning during the microwave ablation of the cyst by the needle antenna, and cyst fluid generated from the microwave ablation is sucked. Thus technical effect identical with that of sclerosis therapy is achieved during the microwave ablation.

Description

technical field [0001] The invention relates to a microwave ablation antenna, more specifically, the invention mainly relates to a cyst microwave ablation treatment needle antenna with a liquid pumping structure. Background technique [0002] Although microwave heat energy has only been used in the clinical treatment of tumors for a short period of more than ten years, it has rapidly developed into a minimally invasive and efficient method in the comprehensive treatment of tumors, and is known as one of the main representative technologies for green tumor treatment. . Microwaves at the medical energy level can produce rapid and efficient thermal effects and dehydration effects when propagating in human tissue, and within a few minutes, a spherical heat field with a center temperature greater than 100°C and an edge greater than 60°C can be formed in the body tissue. The tumor cells inside are quickly coagulated and inactivated under the action of high temperature and dehyd...
