Abstract
Systems and subsystems for closing 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 a closure subsystem that moves independently of other subsystems that are operable independently of each other.

1-15. (canceled)
A closure subsystem comprising:
- a first closure input puck engageable with a first closure robotic output;
- a cam gear rotatably engaged with the first closure input puck, the cam gear comprising a cam track;
- and
- a yoke pin coupled directly or indirectly to a closure tube and movable from a first position to a second position in response to a rotation of the cam gear, the yoke pin extending into the cam track,
- wherein the cam track is configured to provide a non-linear movement profile of the yoke pin such that different sections along the cam track provides different movement profiles for translation of the closure tube.
