Abstract

A surgical instrument includes an ultrasonic blade and a mechanical harmonic generator coupled to the ultrasonic blade. The mechanical harmonic generator includes an exciter wheel operatively coupled to an electric motor. The exciter wheel, when rotated by the electric motor, causes the ultrasonic blade to vibrate at a reference frequency. In some embodiments, the exciter wheel may be in contact with the ultrasonic blade and rotate on the ultrasonic blade by stick-slip motion. Additionally, the mechanical harmonic generator may include a resonator assembly and a tensile vibrator, and the exciter wheel may be contact with the resonator assembly or the tensile vibrator.
