Abstract
An ultrasonic treatment apparatus comprises a hand piece, and an RF power supply unit. The hand piece includes vibrator cover, a sheath connected thereto, a hollow cylindrical member, an ultrasonic vibrator in the cover for generating ultrasonic vibrations, a probe arranged in the sheath, for externally transmitting ultrasonic vibrations generated by the vibrator, and a cord for transmitting a high-frequency current from the RF power supply unit to the probe. The cover and sheath are composed of an insulating member, for preventing the high-frequency current transmitted by the probe from being externally leaked.
