Abstract

A surgical stapling instrument comprising an elongate shaft assembly that that defines a shaft axis and includes a surgical end effector that is operably coupled thereto by an articulation joint. The surgical instrument further includes a rotary articulation member that is supported for rotation travel about a rotary axis that is transverse to the shaft axis. A first distal articulation driver assembly and a second distal articulation driver assembly operably interface with the surgical end effector and the rotary articulation member such that rotation of the rotary articulation member causes the first and second distal articulation drivers to articulate the surgical end effector relative to the shaft axis.
