1. An ultrasonic surgical clamp apparatus comprising:
- a housing;
an outer sheath extending from the housing, the outer sheath having at least one articulating portion and a non-articulating portion;
an inner actuating member reciprocably positioned within said outer sheath for rotation therewith with respect to said housing;
an ultrasonic waveguide positioned within said outer sheath and having an end-effector extending distally of the distal end of the outer sheath, the waveguide having at least one articulating portion and a non-articulating portion, the waveguide further adapted to receive a vibrational energy and to propagate the vibrational energy from the non-articulating portion to the articulating portion;
a clamp arm pivotally mounted on the distal end of the outer sheath for pivotal movement with respect to the end-effector for clamping tissue between the clamp arm and the end-effector, the clamp arm being operatively connected to the actuating member so that reciprocable movement of the actuating member pivotally moves the clamp arm with respect to the end-effector;
an operating lever pivotally mounted on said housing, and a clamp drive mechanism interconnecting the operating lever with the actuating member so that pivotal movement of the operating lever reciprocably moves the actuating member for pivotally moving the clamp arm;
an articulating knob coupled to the housing;
and an articulation mechanism cooperating the with the articulating knob to effect articulation of the articulating portion of the outer sheath between a first position where the articulating portion of the outer sheath is disposed at an angle to the non-articulating portion of the outer sheath and a second position where the articulating portion of the outer sheath is substantially coaxial with the non-articulating portion of the outer sheath.

Abstract
An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation, and clamping of tissue by cooperation of a clamping mechanism of the apparatus with an associated ultrasonic end-effector. Selective articulational positioning of the end-effector is achieved by the provision of an articulating mechanism incorporated into the clamp coagulator apparatus. The arrangement permits an elongated portion of the apparatus to be selectively articulatably positioned with respect to an apparatus housing.
