25. A stapling system for use with a surgical robot, wherein the stapling system comprises:
-
a housing comprising an attachment portion configured to be mounted to the surgical robot; an elongate shaft extending from said housing; and a loading unit attached to said elongate shaft, wherein said loading unit comprises; a loading unit shaft extending from said elongate shaft; and an end effector extending from said loading unit shaft, wherein said end effector comprises; a first jaw; a second jaw, wherein said second jaw is movable relative to said first jaw between an open position and a closed position; an anvil, comprising; a tissue facing surface; and a plurality of staple forming pockets defined in said tissue facing surface; and a staple cartridge, comprising; a first deck surface positioned a first distance from said tissue facing surface when said second jaw is in said closed position; a second deck surface positioned a second distance from said tissue facing surface when said second jaw is in said closed position, wherein said first distance and said second distance are different; a plurality of staple cavities located within said first deck surface and said second deck surface; and a plurality of staples stored in said staple cavities, wherein said plurality of staples comprises;
a first row of staples, wherein said first row of staples are sequentially ejected from said staple cartridge during a firing stroke, and wherein said first row of staples contact said staple forming pockets and form a first formed staple height when ejected; and
a second row of staples, wherein said second row of staples are sequentially ejected from said staple cartridge during said firing stroke, wherein said second row of staples contact said staple forming pockets and form a second formed staple height when ejected, and wherein said first formed staple height and said second formed staple height are different. - View Dependent Claims (26)

27. A stapling system for use with a surgical robot, wherein the stapling system comprises:
-
a housing, comprising, an attachment portion configured to be mounted to the surgical robot; and a drive system configured to receive rotary motions from the surgical robot; an elongate shaft extending from said housing; and a loading unit attached to said elongate shaft, wherein said loading unit comprises; a loading unit shaft extending from said elongate shaft; and an end effector extending from said loading unit shaft, wherein said end effector comprises; a first jaw; a second jaw, wherein said second jaw is movable relative to said first jaw between an open position and a closed position; an anvil, comprising; a tissue facing surface; a plurality of staple forming pockets defined in said tissue facing surface; and a longitudinal cavity; a staple cartridge, comprising; a longitudinal slot; a first deck surface positioned a first distance from said tissue facing surface when said second jaw is in said closed position; a second deck surface positioned a second distance from said tissue facing surface when said second jaw is in said closed position, wherein said first distance and said second distance are different; a plurality of staple cavities; and a plurality of staples removably stored in said staple cavities; and a camming member configured to move within said longitudinal slot of said staple cartridge, wherein said camming member is further configured to move within said longitudinal cavity of said anvil. - View Dependent Claims (28)

29. A stapling system for use with a surgical robot, wherein the stapling system comprises:
-
a housing comprising an attachment portion configured to be mounted to the surgical robot; an elongate shaft extending from said housing; and a loading unit attached to said elongate shaft, wherein said loading unit comprises; a loading unit shaft extending from said elongate shaft; and an end effector extending from said loading unit shaft, wherein said end effector comprises; a first jaw; a second jaw, wherein said second jaw is movable relative to said first jaw between an unclamped position and a clamped position; an anvil, comprising; a tissue facing surface; a first staple forming pocket defined in said tissue facing surface; and a second staple forming pocket defined in said tissue facing surface; and a staple cartridge, comprising; a first deck positioned a first distance from said tissue facing surface when said second jaw is in said clamped position, wherein said first deck comprises a first staple cavity; a second deck positioned a second distance from said tissue facing surface when said second jaw is in said clamped position, wherein said first distance and said second distance are different, and wherein said second deck comprises a second staple cavity; a first staple removably stored in said first staple cavity; a second staple removably stored in said second staple cavity; a first cradle driver movable between an unfired position and a fired position, wherein a first forming distance is defined between said first cradle driver and said first staple forming pocket; and a second cradle driver movable between an unfired position and a fired position, wherein a second forming distance is defined between said second cradle driver and said second staple forming pocket, and wherein said second forming distance is different than said first forming distance. - View Dependent Claims (30)
