Abstract
A surgical device includes a probe, a transducer assembly operatively coupled to the probe for generating an ultrasonic resonant vibration therein, and a frequency generator operatively coupled to the transducer assembly for energizing the transducer component. A control component is operatively connected to the frequency generator for inducing the frequency generator to produce an alternating signal sequence including a first electrical excitation signal and a second electrical excitation signal, wherein the first electrical excitation signal has at least one first ultrasonic frequency and at least one first amplitude collectively selected to generate cavitation bubbles at a wound site to fragment damaged tissue and debride the wound site. The second electrical excitation signal has at least one second ultrasonic frequency and at least one second amplitude collectively selected to generate cavitation bubbles in a substantially reduced amount, thereby allowing for increased transmission of vibratory energy into the debrided tissues for enhancing healing.
