供給する同軸コネクタと、から成つている。 For this reason, a microwave radiator has been proposed as a device for heating an affected area inside a living body.
This microwave radiator is inserted into the body cavity of a subject, emits microwaves toward the affected area inside the living body, and heats the affected area by utilizing dielectric loss caused within the living body. Therefore, a microwave radiator inserted into a body cavity can effectively treat cancer cells existing inside a body cavity such as the throat or uterus. The microwave radiator for heating therapy inserted into a body cavity is composed of an applicator body that emits microwaves, and a coaxial connector that supplies microwaves to the applicator body.
