An end effector includes first and second jaw members that are pivotablerelative to one another between open and clamped configurations about a pivotaxis.The first and second jaw members each define a pivot hole which defines thepivotaxis. The first and second jaw members also each define an articulation axisthat isorthogonal to the pivot axis and position distal of the pivot axis. The firstand secondjaw members are articulatable about the articulation axis between straight andfullyarticulated configurations. 6
