Title: ULTRASONIC SURGERY SYSTEM AND METHOD FOR OPERATING ULTRASONIC SURGERY SYSTEM
Abstract:
This ultrasonic surgery system is provided with an ultrasonic vibrator (24), a probe, a detection circuit (813), a calculation circuit (814), and a comparison circuit (815). The ultrasonic vibrator (24) ultrasonically vibrates. The probe treats body tissue by means of ultrasonic vibration. The detection circuit (813) detects a pressing force applied by the probe. The calculation circuit (814) calculates the product of the pressing force, a probe amplitude, and a probe resonant frequency. The comparison circuit (815) compares the value of the product thus calculated with the value of a predetermined product corresponding to the body tissue. The control circuit generates a signal corresponding to comparison results.
