The invention discloses a microwave and radio frequency cooperative rotation global irradiation hyperthermia system, which comprises an intelligent control unit, a microwave rotary heating mechanism connected with the intelligent control unit, a capacitive radio frequency rotary heating mechanism, and a temperature measuring mechanism; The rotating heating mechanism and the capacitive radio frequency rotating heating mechanism rotate and irradiate the heating area around the human body heat treatment area for heating in different areas, and complement each other with deep and shallow layered diathermy to realize uniform heating of various tissues in the human body heat treatment area; The obtained internal temperature data of the human body is used as a reference system, and it cooperates with nuclear magnetic thermal imaging technology to perform non-invasive real-time and accurate temperature measurement in the body, to achieve precise temperature control, and to achieve accurate high fever and scalding in the whole area.

Description

technical field [0001] The invention relates to the medical field, in particular to a microwave radio frequency coordinated rotation global irradiation hyperthermia system. Background technique [0002] As we all know, surgery, chemotherapy, and radiotherapy are the most conventional methods for the treatment of cancer. They alone or in combination with each other have good curative effect on the radical cure of early-stage non-metastatic tumors. Therefore, researchers in the medical field all over the world have long been committed to finding and exploring new treatment approaches. History records that in 1866, German doctor Busch noticed that one of his cancer patients did not receive any anti-cancer treatment, but the cancer disappeared unexpectedly due to high fever caused by erysipelas infection. He first proposed the theory of hyperthermia that high fever can cure cancer. In 1893, Coley published his "fever therapy" in the "American Journal of Medicine", experimentall...

AI Technical Summary

Problems solved by technology

However, from the actual application of N-9001 microwave tumor therapy instrument (915MHz) developed by Jiangsu Nuovan Medical Equipment Co., Ltd. and UNI-3000 microwave hyperthermia instrument (2450MHz) developed by Hunan Youli Medical Technology Co., Ltd., there are limitations of microwave hyperthermia. Technical deficiencies, in-depth research found that the root causes are: firstly, the depth of microwave diathermy is not enough, usually no more than 6cm (including fat thickness), and the coverage area of ​​directional heating is very small, which is limited to the treatment of superficial tumors that have not metastasized;

[0009] The third is the radio frequency hyperthermia device for tumors, which is a new type of electromagnetic hyperthermia device based on the research and improvement of microwave hyperthermia technology defects. Although it has broken through the limitation of diathermy depth, the application effect is still not optimistic, and it is difficult to cure the diffusion and metastasis. the tumor

Through in-depth research on various radio frequency thermotherapy devices such as Jilin Maida NRL-003 (30-40MHz difference frequency), Japan FR-8 (8MHz), and American BSD-2000W (60~120MHz), it is found that these radio frequency hyperthermia devices are all There are two common problems: first, radio frequency heating can easily lead to overheating of the superficial fat layer, which must be cooled with a water bag; second, the current radio frequency hyperthermia device adopts multi-group capacitive radio frequency heating mechanism to directional cross radiation to strengthen the heating The tumor lesions discovered by scalding are lacking in the thinking of global hyperthermia and the concept of radical cure

[0011] In addition, the field survey also found that there are shortcomings in today's internal temperature measurement technology of the human body. All kinds of thermotherapy equipment are not equipped with accurate internal temperature measurement instruments, and thermotherapy cannot accurately control temperature. For safety reasons, it is forced to lower the temperature to sacrifice the effect of thermotherapy Conservative irradiation also affects the real effect of hyperthermia equipment, so the current hyperthermia devices have not achieved the expected effect

[0012] At present, there are only two kinds of temperature measurement suitable for anti-electromagnetic interference in the body. One is the optical fiber method, which can accurately measure the temperature of certain positions in the body through invasive insertion. Although it is not subject to electromagnetic interference, it can perform multi-point temperature measurement in the body. , but due to the invasive insertion, it not only increases the pain and infection risk of the patient, but also is restricted by many factors and cannot reach any place in the human body (such as the liver, lungs, kidneys and other organs), so it is impossible to obtain all the internal organs of the human body. Location temperature information

Another nuclear magnetic resonance method uses magnetic resonance heat source imaging technology combined with big data to calculate through software. Although it can non-invasively obtain temperature information in the human body, this method has large temperature measurement errors and is not conducive to precise temperature control.
