A control for an ultrasonic surgical instrument is described wherein a transducer having an elongate tip is vibrated to perform surgery. The amplitude of the vibrations by the tip are controlled and the power delivered to the tip can be set so that the operator of the instrument can in effect render the instrument sensitive to different tissues to avoid damage thereto and enhance the safety of the patient.
