Abstract
The embodiment of the invention discloses a torsional vibration type ultrasonic scalpel system. The system comprises an ultrasonic assembly and a cutter. The ultrasonic assembly comprises an ultrasonic transducer and an amplitude-change pole. The ultrasonic transducer is used for generating ultrasonic vibration signals. The amplitude-change pole is used for amplifying the amplitude of the ultrasonic vibration signals. The centroid of the ultrasonic assembly deviates from the central axis of the ultrasonic assembly.
