Patent ID: 8469903

Claim:
An ultrasonic treatment apparatus comprising: an oscillator configured to selectively oscillate a plurality of ultrasonic signals having different frequencies; a memory configured to contain a data table which includes a plurality of data rows storing in advance frequency data of the ultrasonic signals oscillated by the oscillator, at least one data row among the plurality of data rows storing specific frequency data and other frequency data such that a storage amount of the specific frequency data is larger than that of the other frequency data; a central processing unit (CPU) configured to select one application data row from the plurality of data rows; a plurality of ultrasonic oscillators configured to include a plurality of resonance frequencies corresponding to the plurality of ultrasonic signals and output an ultrasonic wave through an ultrasonic oscillation; a plurality of connectors configured to be connected to the plurality of ultrasonic oscillators respectively; a plurality of switches configured to be each connected to the plurality of connectors; and the CPU, in order to apply an application ultrasonic signal selected based on the application data row among the plurality of ultrasonic signals to any one application ultrasonic oscillator among the plurality of ultrasonic oscillators, configured to control the plurality of switches so as to selectively apply the application ultrasonic signal to an application connector connected to the application ultrasonic oscillator, among the plurality of connectors.
