Microwave treatment method and microwave treatment device

Abstract

The invention relates to a device and a method for using microwaves for removing tumors, stopping bleeding, clotting, relieving pains and improving blood circulation. The method includes: using a camera 28 for shooting a lesion 4, enabling a computer 32 to control a scribing machine 31 to scribe voids 13, 14 and 15 of metal stencils 8, 9 and 10 of a three-dimensional lesion projection, radiating microwave beams 19, 20 and 21 penetrating the voids of the stencils in turns from an opposite three-dimensional direction of the projection direction onto the lesion, and enabling the microwave beams to form a high-temperature microwave radiation area 26 coincident with the three-dimensional projection, wherein the temperature of the high-temperature microwave radiation area 26 is higher than a withstanding temperature 43 DEG C of cancer cells; enabling a normal cell tissue 53 to be positioned in a temperature area 25 formed by radiation of nonoverlapped one-dimensional wave beams, wherein the temperature of the temperature area 25 is lower than 40 DEG C. The metal stencils define radiation ranges and positions, a pulse microwave generator and a lens antenna transmit parallel microwave beams 44, 45 and 46, running water controls radiation sequence, and a pyroelectric infrared thermometer and an overtemperature power cut circuit control the radiation temperature. Accurate heating position and range, safety in treatment, painlessness, quickness, one-time completion and thoroughness in killing of cancer cells and low cost are realized.

Description

technical field [0001] The technology claimed by the present invention belongs to a radiotherapy method and its device, especially a non-invasive, pain-free, non-residual, non-escaping, one-time, microwave treatment method for killing somatic cells of tumor lesions in a few minutes and its devices. Background technique [0002] China Medical Equipment, Volume 6, No. 3, March 2009, "New Progress in the Research and Application of Microwave Therapeutic Instruments" wrote: Microwave physiotherapy, using an appropriate amount of local irradiation, improves the metabolism of local organisms, enhances blood circulation, and enhances immunity. Ability to relieve spasm and relieve pain, anti-inflammatory and desensitization, and promote growth. [0003] Microwave treatment of malignant tumors uses microwave radiation to irradiate the cancer tissue, causing the temperature of the irradiated area to rise and achieve the effect of killing tumor cells. Microwave treatment of tumors in...
