1. A surgical stapling instrument, comprising:
an end effector, comprising:
an anvil; and
a cartridge jaw comprising a channel;
a staple cartridge replaceably seated in said channel, wherein said staple cartridge comprises:
a proximal end;
a distal end;
a longitudinal slot extending from said proximal end toward said distal end;
staple cavities;
staples removably positioned in said staple cavities; and
staple drivers configured to drive said staples toward said anvil during a staple firing stroke;
a sled movable from a proximal position to a distal position during said staple firing stroke;
a firing beam configured to distally advance said sled during said staple firing stroke, wherein said firing beam comprises:
a first lateral projection configured to engage said anvil; and
a second lateral projection configured to engage said cartridge jaw; and
a lockout configured to prevent the surgical stapling instrument from performing said staple firing stroke when said staple cartridge seated in said channel is spent, wherein said sled abuts said firing beam to permit the surgical stapling instrument to perform said staple firing stroke when said staple cartridge is seated in said channel and said sled is in the proximal position.
