Ultrasonic surgical apparatus |
摘要 |
A probe is connected to an ultrasonic vibrator and can transmit ultrasonic vibrations to a living body tissue. A PLL circuit can generate a drive signal for driving the ultrasonic vibrator. A P-value detecting circuit detects a voltage peak value and current peak value of the drive signal to be supplied from the PLL circuit to the ultrasonic vibrator. A standardizing circuit standardizes voltage information and current information of the drive signal based on a result of the P-value detecting circuit. A comparing circuit is a comparing unit for comparing voltage information standardized by the standardizing circuit and current information standardized by the standardizing circuit. A CPU identifies an abnormality of the probe based on a comparison result of the comparing circuit. |
