Description

TECHNICAL FIELD

[0001] The utility model relates to a multi-mode microwave treatment device belongs to microwave treatment field. BACKGROUND

[0002] The application of microwave treatment instrument in the medical field has made certain progress, but still has some obvious limitations. At present, the design of most microwave treatment instruments is relatively single, and they can usually only reach a temperature of up to 120℃, which limits their effectiveness in treating some specific diseases. For example, when treating skin diseases such as tumors, these devices often cannot achieve effective hemostasis or local carbonization due to insufficient temperature, thereby affecting the treatment effect. In addition, for diseases such as skin cancer, nasopharyngeal carcinoma, vaginal and anal tumors, which require higher temperature for coagulation therapy, the temperature range of existing microwave treatment instruments is obviously insufficient to meet the treatment needs.

[0003] More worrying is that existing microwave treatment instruments often have unsatisfactory treatment effects when treating diseases such as age spots, vascular nevi, facial pigmented nevi, and multiple fibromas due to temperature and functional limitations. This not only affects the treatment experience of patients, but also to some extent limits the rational use of medical resources. The waste of medical resources not only reflects in the inefficient use of equipment, but also in the need for patients to receive multiple treatments or seek other more complex treatment methods, thereby increasing medical costs and patient suffering.

[0004] In addition, existing microwave treatment instruments also have deficiencies in operational flexibility and adaptability. They usually can only be equipped with one or a few types of microwave physiotherapy heads, which limits the diversity and targeting of treatment. When facing different types of diseases and treatment needs, doctors often need to change different equipment or adopt different treatment methods, which not only increases the complexity of operation, but also prolongs the treatment time.

[0005] In summary, the deficiencies of existing microwave treatment instruments in temperature range, functional diversity, and operational flexibility have become a bottleneck that limits their further application and development in the medical field. Therefore, developing a new type of microwave treatment instrument that can overcome these limitations is of great significance for improving medical efficiency, improving patient treatment effect, and optimizing the use of medical resources.
