Abstract

The invention relates to a high-power 2450MHz solid-state-source microwave therapy apparatus. The microwave therapy apparatus is composed of a crystal oscillation phase-locked microwave oscillator, a solid-state amplifier, a circulator, a microwave power switch, an embedded microprocessor, a liquid crystal touch screen, a power supply and the like. The microwave therapy apparatus is provided with pulse modulation frequencies of 1Hz, 5Hz, 10Hz and 100Hz except the operating frequency of 2450MHz, output waves comprise continuous waves and four frequency pulse modulating waves, microwave output can be one-way or two-way, and therapy time can be switched automatically as required. The microwave therapy apparatus can be applied to tumor microwave ablation, microwave palliative treatment, microwave operation, microwave physiotherapy and the like. As a new generation of the existing 2450MHz magnetron microwave therapy apparatus, the microwave therapy apparatus has the advantages of being good in safety performance, low in power consumption, long in service life, high in output power, high in power stability and the like.

Description

technical field [0001] The invention relates to a multi-functional and multi-purpose high-power 2450MHz solid-state source microwave therapy instrument, which is used for microwave ablation of tumors, microwave dry breath therapy, microwave surgery, microwave physiotherapy and other treatments, and belongs to the technical field of medical instruments. Due to the high frequency of 2450MHz, it generates a lot of heat and makes the radiator less difficult to manufacture. Therefore, microwave ablation and heating of tumors are widely used at home and abroad. Background technique [0002] Existing technologies such as patent numbers: 87208231, 89205095.0, and the high-power microwave therapeutic apparatus used in domestic and Japanese countries for microwave ablation of tumors and microwave physiotherapy still use 2450MHz magnetron microwave source, poor frequency and power stability, and microwave is useless The radiation power is large, the power consumption is large, the fila...
