1. A surgical instrument comprising:

  • a handle assembly;

    an elongated shaft assembly operably interfacing with said handle assembly and defining a longitudinal axis;

    a surgical end effector operably coupled to the elongated shaft assembly and configured to cut and staple tissue upon application of actuation motions thereto;

    at least one articulation member operably supported by said elongated shaft assembly; and

    an articulation system comprising;

    an articulation transmission operably supported by said handle assembly and operably interfacing with said at least one articulation member; and

    an actuator member rotatably supported on said handle member for selective rotation about an actuation axis that does not transversely intersect said longitudinal axis, said actuator member interfacing with said articulation transmission such that rotation of said actuator member in a first rotary direction about said actuation axis causes said at least one articulation member to articulate said surgical end effector relative to said longitudinal axis in a first articulation direction and rotation of said actuator member in a second rotary direction about said actuation axis causes said at least one articulation member to articulate said surgical end effector relative to said longitudinal axis in a second articulation direction relative to said longitudinal axis.
