Abstract
A surgical stapling instrument. Various embodiments include an actuation system for selectively generating a plurality of control motions. A surgical end effector is operably coupled to the actuation system. The actuation system interfaces with an actuation member configured to operably engage rotatable camming members to fire staples within the end effector into forming contact with an anvil portion of the end effector.

1-20. (canceled)
A surgical attachment assembly configured to be operably attached to a surgical robot, wherein said surgical attachment assembly comprises:
- a housing, comprising:
- an attachment portion configured to be mounted to the surgical robot;
- and
- a drive system configured to generate rotary motions;
- a fastener cartridge comprising a plurality of fasteners removably stored therein, wherein said plurality of fasteners are arranged in at least two spaced fastener lines;
- a drive shaft configured to rotate in response to said rotary motions;
- a plurality of fastener deploying surfaces, wherein each said fastener deploying surface comprises a camming surface;
- and
- an actuation member operably interfacing with said drive shaft, wherein said actuation member is configured to translate axially within said fastener cartridge between a starting position and an ending position in response to the rotation of said drive shaft, wherein said actuation member is configured to rotate said plurality of fastener deploying surfaces by interacting with said camming surfaces, and wherein said plurality of fastener deploying surfaces are configured to sequentially eject said plurality of fasteners are sequentially ejected as said actuation member translates between said starting position and said ending position.
A surgical instrument, comprising:
- an actuation system for selectively generating a plurality of rotary motions;
- and
- an end effector operably coupled to said actuation system, wherein said end effector comprises:
- a fastener cartridge comprising a plurality of fasteners arranged in at least two spaced fastener lines;
- a drive shaft configured to rotate in response to said rotary motions;
- a plurality of fastener deploying surfaces;
- and
- an actuation member operably interfacing with said drive shaft, wherein said actuation member is translated axially within said fastener cartridge between a starting position and an ending position when said drive shaft is rotated, wherein said fastener deploying surfaces are rotated in response to said actuation member being translated from said starting position to said ending position, and wherein said fasteners are sequentially ejected as the actuation member is driven from said starting position to said ending position.
A surgical attachment assembly configured to be operably attached to a surgical robot, wherein said surgical attachment assembly comprises:
- a housing, comprising:
- an attachment portion configured to be mounted to the surgical robot;
- and
- a drive system configured to generate rotary motion;
- a drive shaft configured to rotate in response to said rotary motion;
- and
- a fastener cartridge, comprising:
- a plurality of fasteners removably stored therein, wherein said plurality of fasteners are arranged in at least two spaced lines;
- a plurality of camming surfaces;
- and
- an actuation member operably interfacing with said drive shaft, wherein said actuation member is configured to translate within said fastener cartridge between a starting position and an ending position in response to the rotation of said drive shaft, and wherein said actuation member rotates said camming surfaces in sequential order as said actuation member translates between said starting position and said ending position to deploy said fasteners.
