Magnetic field induction thermal therapy device

Abstract

The invention provides a magnetic field induction thermal therapy device, and relates to the technical field of medical equipment. The magnetic field induction thermal therapy device is characterizedin that two U-shaped magnetic circuit openings are arranged symmetrically opposite to each other; and the second Helmholtz coil is wound on the lower transverse side of each U-shaped magnetic circuit,and the first Helmholtz coil is wound on the longitudinal side of each U-shaped magnetic circuit, and the second Helmholtz coil is wound on the longitudinal side of each U-shaped magnetic circuit. The first Helmholtz coil and the second Helmholtz coil are connected with the power supply; the invading needle is inserted into the human body, which is composed of stainless steel needle body and ferrite needle body; the ferrite needle body is inserted into the end head of the stainless steel needle body. The invention has smaller microwave trauma, cheaper price and stronger practicability than the radio frequency sintering system.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a magnetic field induction thermotherapy device. Background technique [0002] Since ancient times, whether it is the human body or the surrounding environment, the simplest and most effective way for us to deal with the virus source is to use "fire". Modern scientific circles have found that tumors and cancer cells are more sensitive to temperature than normal tissue cells. It is estimated that such cells lose their vitality at about 42°C, and tend to die when they reach 46°C. Hyperthermia technology is a technique in which the physical concept lies in the treatment of human diseases. However, in order to generate high temperature to achieve the effect of hyperthermia, there are many physical means, such as laser, ultrasonic and other technologies. [0003] In recent years, regardless of medical or surgical treatment of the human body, great emphasis has been placed ...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages: The frequency and the current control of the current to the needle tip are relatively unstable, and it is easy to cause damage to normal tissues due to excessive temperature conduction, and the range is small, requiring multiple insertions, which is prone to discomfort

[0007] Disadvantages: better than radio frequency, but not popular

Although the structure is simple and there are already products on the market, most of them are far beyond the range of patients' affordability, so they cannot be regarded as an ideal electromagnetic hyperthermia technology
