Problems solved by technology

[0003] Another problem existing in the existing radio frequency hyperthermia equipment is that a water bag needs to be filled between the radiator and the patient's body to facilitate the coupling of electromagnetic wave energy, and disease patients, especially those with advanced stages, are generally in poor health, and it is difficult to bear such a heavy medical device for a long time. Water bag, which makes the patient feel very painful during the treatment
[0004] The third problem of the existing radio frequency hyperthermia equipment is that only a part of the radio frequency energy generated by the radio frequency source can be transmitted into the human body, and a part will be radiated into the air, so that the medical staff will be irradiated, especially the operator of the equipment. to adversely affect

Embodiment Construction

[0023] Fig. 4 shows the system diagram of the present invention, in the figure, the radio frequency power source 1 first produces radio frequency energy, then divides the radio frequency energy into N paths through the matching feeding branch network 2, and is respectively connected to the N feeders of the resonant cavity through feeders, Therefore, the electromagnetic field needed for treatment is excited in the resonant cavity 3 , and the electromagnetic field is absorbed by the human body 4 in the resonant cavity 3 . Figure 5 is a schematic diagram of a specific embodiment of the resonant cavity. The resonant cavity is composed of an outer cylindrical metal shell 5, and cylindrical conductors 6, 7 with inner openings opposite and juxtaposed. There is a gap between the cylindrical conductors 6, 7. , each cylindrical conductor has a certain distance from the bottom surface of the metal shell, and the feeders 8, 9, 10, 11 on the resonant cavity are evenly distributed near the g...

Abstract

A RF thermotherapeutic apparatus for eliminating the over-heat of subcutaneous fat during thermotherapy is composed of a RF power source, a power feeding circuit, multiple electric feeders, and a resonance cavity consisting of a metallic casing and two cylindrical conductors with opposite openings and openable bottom.

Description

1. Technical field: [0001] The invention belongs to the field of medical physical therapy, and in particular relates to a device for treating diseases by using radio frequency energy. 2. Background technology: [0002] At present, hyperthermia technology has been widely used in the clinic of various diseases, such as gastric cancer, lung cancer, pancreatic cancer, etc., which can be divided into two types: biological hyperthermia and physical hyperthermia. Among them, biological hyperthermia is to use microbial infection to cause self-fever in patients, such as using Plasmodium to cause patients to suffer from malaria and cause fever (Chinese patent named "Using Plasmodium to obtain safe high fever and related clinical parameters of human body", publication number CN1432407A ). Physical hyperthermia is the use of physical methods to produce hyperthermia effects. It achieves therapeutic purposes by directly generating heat in the superficial or deep parts of the patient's bo...
