Electric heat therapy needle

Abstract

The invention relates to an electric heat therapy needle, comprising a body, a heat-generating assembly and a temperature sensing assembly. The body is provided with a metal tip part. The heat-generating assembly is disposed in the metal tip part. The temperature sensing assembly is disposed in the metal tip part. The electric heat therapy needle can burn tumor tissues and adjust temperature, can achieve high treatment efficacy at low cost, and can alleviate pains of a patient during a process of burning the tumor.

Description

technical field [0001] The present invention relates to a treatment needle, in particular to an electrothermal treatment needle. Background technique [0002] Existing thermotherapy methods for tumors include microwave hyperthermia, radiofrequency ablation hyperthermia, and ultrasonic focused hyperthermia. Among them, both microwave hyperthermia and radio frequency ablation hyperthermia are directly inserted into the tumor with needle-shaped electrodes; microwave hyperthermia uses the microwave radiator at the end of the microwave electrode to generate thermal effect, while radio frequency ablation hyperthermia uses the radio frequency current of the electrode needle , through ion excitation and conversion into heat energy, causing coagulation necrosis of local tumor tissue, so as to achieve the purpose of tumor treatment. However, the treatment costs of the above-mentioned methods are quite high and cause great pain to the patients. [0003] Therefore, how to provide a lo...
