Abstract
Systems and subsystems for articulating an end effector of a stapler are disclosed. More specifically, the present disclosure relates to systems, devices, and subsystems for attachments for robotic surgeries. The surgical instrument is a robotic attachment. The surgical instrument includes an articulation subsystem that moves independently of other subsystems that are operable independently of each other.

1-15. (canceled)
An articulation subsystem for a surgical instrument comprising:
- a rotatable shaft having a longitudinal axis;
- an articulation rod extending along the longitudinal axis of the rotatable shaft and being rotationally coupled to the rotatable shaft;
- a first articulation bushing slidable from a first position to a second position along the longitudinal axis of the rotatable shaft, the first articulation bushing being rotationally coupled to the rotatable shaft;
- a first rack movable with respect to the longitudinal axis of the rotatable shaft, the first rack being rotationally independent of the rotatable shaft and the first articulation bushing;
- and
- a first rack gear engaged with the first rack,
- wherein rotation of the first rack gear moves the first rack with respect to the longitudinal axis, and
- wherein movement of the first rack with respect to the longitudinal axis imparts an axial force onto the first articulation bushing moving the first articulation bushing from the first position to the second position.

An articulation subsystem for a surgical instrument comprising:
- a rotatable shaft having a longitudinal axis;
- a distal channel retainer coupled to an end effector, the distal channel retainer being pivotable about an articulation joint;
- a first articulation bushing slidable from a first position to a second position along the longitudinal axis of the rotatable shaft;
- an articulation rod extending distally from the first articulation bushing and coupled at a distal end to the distal channel retainer;
- and
- a first rack movable with respect to the longitudinal axis of the rotatable shaft,
- wherein movement of the first rack with respect to the longitudinal axis imparts an axial force onto the first articulation bushing moving the first articulation bushing from the first position to the second position, and
- wherein movement of the first articulation bushing from the first position to the second position actuates the articulation rod causing the distal channel retainer to pivot about the articulation joint.
