Beschreibung
Zusammenfassung:	An ultrasonic surgical system includes an ultrasonic transducer, a probe connected to the ultrasonic transducer and coming in contact with a treatment target, a detector detecting current and voltage which are supplied to the ultrasonic transducer, a driver driving the ultrasonic transducer to oscillate at its resonance point, and a controller. The controller detects a mechanical load exerted on the probe based on the voltage detected by the detector, and outputs a signal for reducing the mechanical load to the driver when the detected mechanical load is higher than a predetermined value.
