Embodiment Construction

[0030] An electromagnetic heat treatment needle according to a preferred embodiment of the present invention will be described below with reference to related drawings, wherein the same elements will be described with the same element symbols.

[0031] figure 1 It is a schematic diagram of an electromagnetic heat therapy needle 1 according to a preferred embodiment of the present invention, figure 2 It is a schematic cross-sectional view of the electromagnetic heat therapy needle 1 . Please refer to figure 1 and figure 2 To illustrate the technical characteristics of the electromagnetic heat treatment needle 1. What needs to be explained first is that the electromagnetic heat treatment needle 1 can be used in conjunction with a high-frequency heater (not shown in the figure), the high-frequency heater generates an alternating magnetic field, and the electromagnetic heat treatment needle 1 induces an alternating magnetic field to generate an eddy current or Thermal energy...

Abstract

An electromagnetic thermotherapy needle includes a needle body, a covering element, and a holding portion. The material of the needle body includes a magnetically susceptible material. The needle body is formed integrally as one piece and includes a front portion and a rear portion. The front portion has a tip end, and a radial width of the front portion is larger than that of the rear portion. The covering element covers the rear portion, and includes a magnetically non-susceptible material. The holding portion is connected with the covering element or the needle body. The electromagnetic thermotherapy needle provided by the invention can decrease the therapy cost and prevent the damage of normal tissues during the therapy.

Description

technical field [0001] The present invention relates to a heat therapy needle, in particular to an electromagnetic heat therapy 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 structure of the electrode needle is complex, the installation steps are rather cumbersome, and the electrode needle cannot be reused...
