Abstract
An ultrasonic vibration treatment apparatus comprising an ultrasonic vibration treatment device including an ultrasonic vibrator and an ultrasonic wave transmitter probe, a detecting element opposing the transmitter for applying light to the transmitter and receiving the light reflected from the transmitter, thereby to detect the amplitude of vibration of the treatment device, and a power source controller for reducing the power supplied to the vibrator, or stopping the power supply to the vibrator, in accordance with a detection signal output by the detecting element. The detecting element quickly detects the charges in the amplitude of vibration of the ultrasonic vibration treatment device, said charge in the amplitude representing the charges in the vibration condition of the vibration treatment device from actual driving to idling, or vice versa. The power source controller fast responds to the detection signal output by the element, and immediately controls the treatment device in idling state, so as to prolong the lifetime of the treatment device.
