Abstract
Systems and methods of controlling an ultrasonic surgical tool with a console are provided. A first drive signal is applied to the ultrasonic surgical tool. A characteristic of a harmonic signal resulting from application of the first drive signal to the ultrasonic surgical tool is acquired. A cancellation signal is generated based on the characteristic of the harmonic signal. The first drive signal and the cancellation signal are combined to produce a second drive signal that is sinusoidal. The second drive signal is applied to the ultrasonic surgical tool such that presence of the harmonic signal resulting from application of the second drive signal is reduced relative to presence of the harmonic signal resulting from application of the first drive signal.
