1. A surgical instrument, comprising:
an end effector, comprising:
an elongate channel; and
an anvil operably coupled to said elongate channel, wherein said anvil and said elongate channel are configurable between an open configuration and a closed configuration, and wherein said anvil comprises an anvil slot;
a distal beam head movable between a proximal position and a distal position, wherein said distal beam head comprises:
a cutting edge;
an upper flange configured to slidably engage said anvil; and
a lower flange configured to slidably engage said elongate channel, wherein said upper flange and said lower flange are configured to affirmatively space said elongate channel and said anvil as said distal beam head moves toward said distal position;
an articulation joint;
a firing bar configured to transfer a firing motion to said distal beam head through said articulation joint, wherein said firing bar comprises a plurality of laminated strips, and wherein a thickness of said distal beam head is greater than a thickness of at least two strips of said plurality of laminated strips; and
a joint, wherein said firing bar is connected to said distal beam head at said joint.
