Abstract
An ultrasonic surgical instrument comprises a handpiece and an ultrasonically actuated blade distal to the handpiece. The instrument includes an activation member that is operable to selectively activate the blade and a controller that is operable to select the energy level at which the blade will be activated. The activation member may comprise capacitive switches; resistive sensors; resonant cavity switching technology; infrared sensing technology; technology that uses a resonant, standing wave on a surface that is perturbed by the presence of a finger; and/or any other suitable type of technology. The controller may comprise the same. The controller may permit selection from three or more available ultrasonic energy levels. The activation member and/or controller may be manipulated from various longitudinal positions on the handpiece and/or various rotational positions about the handpiece, such that the handpiece may be gripped in a variety of ways.
