ABSTRACT:
An ultrasonic operation apparatus performs a treatment through the utilization of an ultrasonic oscillation and comprises a handpiece serving as a surgical tool and an apparatus body including a power source unit for supplying electric power to the handpiece. The handpiece is exchangeably attachable to, and detachable from, the apparatus body. The handpiece comprises an ultrasonic oscillation element for generating an ultrasonic oscillation, a probe for transmitting the ultrasonic oscillation which is generated from the ultrasonic oscillation element to a region of interest of a human being and a signal generating unit for generating a signal corresponding to a resonant frequency inherent in the ultrasonic oscillation element and hence the probe. The power source unit includes a power amplifying unit for receiving a signal corresponding to the resonant frequency inherent in the handpiece from the signal generation unit of the handpiece, amplifying the signal and generating a corresponding drive signal, and a connecting/transmitting unit for transmitting the corresponding drive signal which is generated at the power amplifying unit to the handpiece.
