Abstract:
1. A forceps, comprising: a housing having at least one transducer, the at least one transducer configured to generate a mechanical vibration in response to energy transmitted thereto from an energy source; a shaft assembly extending from the housing, the shaft assembly including at least one articulating member and at least one clamping member and a longitudinal axis defined therethrough; an end effector assembly disposed at a distal end of the shaft assembly and including a pair of opposing jaw members pivotable between approximated and unapproximated configurations in response to movement of the at least one clamping member, the at least one articulating member being configured to articulate the pair of opposing jaw members relative to the longitudinal axis of the shaft assembly; and a waveguide assembly positioned within the shaft assembly and configured to receive the mechanical vibration generated by the transducer, the waveguide assembly being at least partially positionable within at least one of the opposing jaw members; wherein the end effector is longitudinally translatable between a proximal position and a distal position with respect to the shaft assembly and the waveguide assembly to allow the end effector assembly to articulate relative to the shaft and the waveguide assembly when the end effector assembly is disposed in the distal position.
