A firing bar longitudinally translates between the handle portion and the end effector. The firing bar head is thickened in order to present an undistorted cutting edge and engagement features to the opposing 10 jaws of the end effector. The firing bar also advantageously includes a thinned or tapered proximal portion in the form of a strip or band that negotiates the articulation mechanism. 15 08/02/1 .va 19075 spcci.doc,241/10 10 20 30 22 23 11 35 12 18 34 - 33 34 2824 16 26 FIG. 1 13 20 30 22 2 18 12 32 16 33 (4 35 28 34 24 FIG. 2 26
