Microwave refers to electromagnetic waves with frequencies between 300MHZ and GHZ. In 1930s, medical workers discovered the biological effects of microwave. Clinically, the interaction between microwave and organism can be divided into two categories, namely microwave-induced thermal effect and non-microwave-induced thermal effect. Microwave hyperthermia used in microwave therapeutic instrument is a non-contact heating method, and there is no possibility of heat and electric burn caused by electrical contact. In recent years, due to the improvement of various technologies, microwave therapy can be carried out in outpatient department without anesthesia, which is simple and safe.
Microwave therapy has been used at home and abroad for many years, and its curative effect has been affirmed by the world medical community. In surgery, it is regarded as a new technology to replace electrocautery, freezing and laser because of its superior hemostasis effect, advanced action principle and slight tissue damage. Microwave therapeutic instrument is a new medical instrument that uses microwaves to treat various diseases. In addition to the characteristics of deep surface heating, it also has the advantages of convenient operation, accurate positioning, high safety, low cost, compact instrument structure and wide adaptability. Different accessories can treat different diseases. Microwave therapeutic instrument is the product of microwave technology, sensor, automatic control and computer software and hardware. It is a safe, convenient and good surgical treatment method, which can be performed directly in outpatient department without anesthesia.
