Microwave and radio frequency combined type tumor ablation equipment and tumor ablation method

Abstract

The invention provides microwave and radio frequency combined type tumor ablation equipment and a tumor ablation method, and relates to the technical field of ablation equipment. The microwave and radio frequency combined type tumor ablation equipment comprises a power module, a storage tank and an ablation needle, liquid metal is stored in the storage tank, the power module is connected with the liquid metal to provide microwave energy and radio frequency energy for the liquid metal, the storage tank is provided with an inlet and an outlet, and the ablation needle is connected with the outlet through an inflow pipe. The ablation needle is connected with the inlet through a backflow pipe. According to the microwave and radio frequency combined type tumor ablation equipment and the tumor ablation method, the ablation needle and the storage tank are communicated through the inflow pipe and the backflow pipe to form a circulation loop, the liquid metal carries microwave energy and radio frequency energy, the temperature of the needle point of the ablation needle can be effectively reduced in the flowing process, and losses of the microwave energy and the radio frequency energy can be reduced; and microwave ablation and radio frequency ablation are integrated, possibility is provided for reducing the number of ablation times, and ablation cost can be reduced.

Description

technical field [0001] The present invention relates to the technical field of ablation equipment, in particular to a microwave radio frequency composite tumor ablation equipment and a tumor ablation method. Background technique [0002] Tumor ablation therapy is more and more widely used in clinical treatment due to its advantages of minimal invasiveness, safety, high operability and good repeatability. Common ablation methods are mainly microwave ablation, radiofrequency ablation and cryoablation. Both radiofrequency ablation and microwave ablation are minimally invasive procedures, with the characteristics of small wound, short hospital stay, liver function protection, and tumor tissue targeting effect, and are the most widely used. [0003] Microwave ablation has fast heating speed and strong penetrating power, and can heat up to 100°C within a few seconds. During ablation, the intratumoral temperature is high, the ablation time is short, and the ablation range is large...
