Description
Technical Field
The invention relates to the field of medical physical therapy, in particular to a non-thermal effect electric field radio frequency thermotherapy instrument.
Background
Currently, thermotherapy is widely used in clinical treatment of various diseases, such as gastric cancer, lung cancer, pancreatic cancer, etc., which can be divided into two types of biological thermotherapy and physical thermotherapy. The biological heat therapy is to use the microbial infection to cause the patient to have self fever; physical thermotherapy is a method of generating thermotherapy effect by physical means, mainly by directly generating heat at superficial or deep part of patient body to achieve therapeutic purpose, for example, using infrared ray, microwave or radio frequency and other technical means to convert corresponding physical energy into heat energy in vivo, thereby raising temperature in body to achieve therapeutic purpose. However, when these methods are applied to the human body, the affected part deep in the human body cannot reach an effective treatment temperature because the physical energy is rapidly attenuated after entering the human body. For the reasons, the infrared and microwave are suitable for body surface or interventional body heating, and the radio frequency energy is suitable for heating treatment of deep internal diseased parts due to longer working wavelength and larger penetration depth, and belongs to internal diathermy.
Most of the existing radio frequency thermal therapy equipment belongs to thermal effect electric field radio frequency thermal therapy, after radio frequency energy acts on a machine body, electrolyte ions in tissues move at a high speed along with frequency to form conduction current, and dielectric particles rotate at a high speed to form displacement current; the loss of current in the tissue is converted to heat, a process by which the body converts electrical energy to thermal energy. When the method is applied to the body, the temperature of the body tissues is obviously increased, and different people have different tolerance degrees, generally about 10 minutes. However, some patients require a long time for the thermal therapy, which requires that the patient stops the thermal therapy for a certain time after reaching the tolerance limit and performs the thermal therapy again after the body temperature drops; thus, not only is the operation troublesome, but also the heat treatment effect is influenced, and in addition, the whole heat treatment time is prolonged, and the pain of the patient is increased.

The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art and provides a non-thermal effect electric field radio frequency thermotherapy instrument which can not cause the temperature of organism tissues to be obviously raised and can prolong the thermotherapy time.

Preferably, the temperature control system comprises a temperature detection unit and a PLC control unit, and the temperature detection unit and the radio frequency emission unit are electrically connected with the PLC control unit; the temperature detection unit is used for detecting the body temperature of a patient in the resonant cavity and transmitting a detected signal to the PLC control unit, and the PLC control unit is used for controlling the output power of the radio frequency emission unit in real time.
