Claim:
1. A handheld ultrasonic surgical device, comprising: a housing defining a top portion, a proximal portion, and a distal portion; a waveguide extending distally from the distal portion of the housing and defining a longitudinal axis, the waveguide having a blade and a moveable jaw member disposed at a distal end thereof, the moveable jaw member pivotable with respect to the blade; a torque knob disposed at the proximal portion of the housing and rotatable about the longitudinal axis defined by the waveguide; a removable ultrasonic generator couplable to the top portion of the housing at the proximal portion thereof, rotation of the torque knob selectively locking and unlocking the removable ultrasonic generator to the housing; a transducer couplable to the removable ultrasonic generator and configured to convert electrical energy to mechanical energy, wherein mechanical energy is transmittable through the waveguide to the blade which causes the blade to oscillate and deliver energy to tissue; a removable battery couplable to the housing and configured to supply electrical energy to the removable ultrasonic generator; and a AC/DC converter couplable to the housing and configured to supply supplemental energy to the removable ultrasonic generator and selectively recharge the removable battery, wherein the AC/DC converter selectively augments the power supplied to the removable ultrasonic generator, such that if the power supplied by the removable battery is insufficient the AC/DC converter directly powers the removable ultrasonic generator.
