Title: Microwave radiator for warming treatment
Inventor: ITO KOICHI
IPC: A61N5/02
Filed: 1988-11-16
Abstract: PURPOSE:To make an electromagnetic energy permeate widely into a focus by extendingly providing an inner conductor and a dielectric body on the extended center line of a narrow high frequency concentric cable body formed of an outer conductor disposed through the dielectric body around the inner conductor, and installing a plurality of ring conductors on the extended dielectric body outer circumferential surface. CONSTITUTION:A high-frequency voltage applied to a high-frequency concentric cable body 10 derives a current determined by the specified impedance of the cable body 10 to inner and outer conductors 1, 3. The electric transmission mode transmitted to the cable body 10 longitudinally generates a current on the outer conductor 3 of the concentric cable body 10. Thus, the current crosses at a right angle to a ring slit between the ring conductors 4 on the outer conductor 3. As the ring slit completely breaks the actual current sent to the outer conductor 3 of the cable body 10, a radiation wave is effectively generated with generating no surface wave electric transmission mode, and thus the circumference of the internal tissue is entirely warmed by its dielectric body loss.
