1. A surgical instrument, comprising:
a housing;
a closure driver configured to transmit a closure motion;
a shaft assembly extending from said housing, wherein said shaft assembly defines a shaft axis and comprises:
a first shaft segment;
a second shaft segment extending distally from said first shaft segment;
a third shaft segment extending distally from said second shaft segment;
a first articulation joint rotatably connecting said first shaft segment and said second shaft segment;
a second articulation joint rotatably connecting said second shaft segment and said third shaft segment, wherein said second articulation joint is positioned distal to said first articulation joint;
a passage defined within said first shaft segment, said second shaft segment, and said third shaft segment;
a closure rod extending within said passage, wherein said closure rod is moved from a proximal position to a distal position in response to said closure motion;
a first jaw;
a second jaw rotatable relative to said first jaw from an open position toward a closed position in response to said closure rod moving from said proximal position to said distal position; and
a firing actuator configured to approximate said first jaw and said second jaw during a staple firing stroke; and
a first articulation cable drivable by a first rotatable articulation input to articulate said second shaft segment about a first articulation axis; and
a second articulation cable drivable by a second rotatable articulation input to articulate said third shaft segment about a second articulation axis, wherein said first articulation cable and said second articulation cable extend alongside said closure rod.
