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.
Claims20
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, wherein the cam track comprises an open position, a high-speed compression region, a high force region, and a constant region, each region having different curvatures, and
- wherein the constant region is shaped such that the yoke pin remains stationary when tracking through the constant region as the cam gear rotates.

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;
- a rotatable shaft;
- a closure tube;
- and
- a closure yoke rotationally independent of the rotatable shaft, axially coupled to the closure tube, and movable from a first position to a second position in response to a rotation of the cam gear, the closure yoke comprising a 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.
