1. A surgical instrument, comprising:
- an end effector comprising an ultrasonic blade and a clamp jaw, the clamp jaw comprising a proximal end, a distal end, a tissue engaging portion on a first side, and a longitudinal channel on a second side, wherein the clamp jaw is rotatable about a pivot point along an arcuate path from a closed tissue engaging position to a fully open position;
wherein in both the closed tissue engaging and the fully open positions the clamp jaw is substantially aligned with a longitudinal axis defined by the end effector;
wherein in the closed tissue engaging position the distal end of the clamp jaw is distal relative to the pivot point; and
wherein in the fully open position the distal end of the clamp jaw is proximal relative to the pivot point;
the surgical instrument further comprising;
an actuator member coupled to the clamp jaw, wherein a longitudinal portion of the actuator member is configured to translate to affect rotation of the clamp jaw between the closed tissue engaging position and the fully open position, and wherein the longitudinal portion of the actuator member translates within the longitudinal channel of the clamp jaw when the clamp jaw is in the fully open position.

24. An ultrasonic surgical instrument, comprising:
-
an end effector comprising an ultrasonic blade and a clamp jaw, the clamp jaw comprising a proximal end, a distal end, a tissue engaging portion, and an actuator engaging portion; an outer tube comprising a pivot point, wherein the proximal end of the clamp jaw is pivotally mounted to the outer tube at the pivot point, wherein the clamp jaw is rotatable about the pivot point along an arcuate path from a closed tissue engaging position to a fully open position, and wherein in both the closed tissue engaging and fully open positions the clamp jaw is substantially aligned with a longitudinal axis defined by the end effector; and an actuator member coupled to the actuator engaging portion of the clamp jaw, wherein a longitudinal portion of the actuator member is configured to move within the outer tube to cause the clamp jaw to rotate between the closed tissue engaging position and the fully open position; wherein the actuator engaging portion of the clamp jaw comprises a longitudinal channel formed on a top surface of the clamp jaw to receive the longitudinal portion of the actuator member therein when the clamp jaw is in the fully open position. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
