    摘要： Circuit for use in a surgical operation including a phase lock loop having a voltage controlled oscillator, and a phase comparator for comparing a phase of a voltage of a driving signal and a phase of a signal representing the vibration phase of the ultrasonic transducer to derive a phase difference therebetween which is applied to the voltage controlled oscillator as a frequency control voltage such that the driving signal is phase-locked with a resonance frequency of the ultrasonic transducer, the improvement being characterized in that during a start period, a reference signal having a frequency which is increased monotonously is applied to the phase comparator such that the frequency of the driving signal is increased until the driving signal is phase-locked with the vibration phase of the ultrasonic transducer vibrating at the resonance frequency. After the phase-lock condition has been attained, the signal representing the vibration phase of the ultrasonic transducer is applied to the phase comparator instead of the reference signal.
