A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. Various embodiments are configured to be operably attached to a robotic system to receive actuation/control motions therefrom.
1. A surgical instrument comprising: an implement portion responsive to firing motions from a robotic system communicating therewith and being diametrically dimensioned for endo-surgical use, the implement portion comprising:an elongate channel coupled to an elongated shaft operably interfacing with
1. A surgical instrument comprising: an implement portion responsive to firing motions from a robotic system communicating therewith and being diametrically dimensioned for endo-surgical use, the implement portion comprising:an elongate channel coupled to an elongated shaft operably interfacing with said robotic system and including a channel slot;an anvil pivotally coupled to the elongate channel, responsive to closing motions generated by said robotic system and applied thereto by the elongated shaft, and including an anvil channel; anda firing device including a distally presented cutting edge longitudinally received between the elongate channel and the anvil, the firing device configured to affirmatively space the anvil from the elongate channel during longitudinal travel between the anvil and elongate channel, by including: an upper member having a first upper surface and a first lower surface that longitudinally slidingly engage the anvil;a lower pin including a second upper surface abutting the elongate channel; anda middle pin including a second lower surface that slidingly engages the elongate channel. 2. The surgical instrument of claim 1, further comprising a staple cartridge engaged by the elongate channel and including a proximally opened slot for receiving the cutting edge of the firing device, the staple cartridge including a plurality of staples cammed upwardly by the distal longitudinal travel of the firing device. 3. The surgical instrument of claim 2, wherein the staple cartridge further includes a plurality of drivers supporting the plurality of staples and a wedge sled responsive to the distal longitudinal travel of the firing device to cam upwardly the drivers and thus form the plurality of staples against the anvil. 4. The surgical instrument of claim 2, wherein the anvil forms an inwardly biased relation to the elongate channel configured to assist the firing device in affirmatively spacing between the anvil and elongate channel during actuation of the staple cartridge. 5. The surgical instrument of claim 2, wherein the staple cartridge is a selected type of a plurality of staple cartridge types, each staple cartridge type characterized by a thickness selected for a desired spacing between the anvil and elongate channel and characterized by staples having a length suitable for the desired spacing. 6. The surgical instrument of claim 5, further comprising a wedge sled comprising a plurality of connected camming wedges each having a preselected height configured for the selected type of staple cartridge, the middle pin of the firing device oriented to abut each of the plurality of staple cartridge types. 7. The surgical instrument of claim 1, wherein the anvil includes a longitudinal slot having an upper surface and a lower surface that slidingly abut respectively the first lower surface and first upper surface of the upper member of the firing device. 8. The surgical instrument of claim 7, wherein the longitudinal slot comprises an internal longitudinal channel communicating with a narrowed vertical slot, and wherein the firing device translates in the narrowed vertical slot such that the upper member having the first upper and first lower surfaces that reside within the internal longitudinal channel for affirmatively spacing the anvil from the elongate channel. 9. The surgical instrument of claim 1, wherein the anvil includes an internal longitudinal slot having a narrowed vertical slot, and wherein the firing device translates in the narrowed vertical slot such that the first upper surface and first lower surface reside within the internal longitudinal slot for affirmatively spacing the anvil from the elongate channel. 10. The surgical instrument of claim 1, further comprising: an articulation joint proximally coupled to the elongate channel; anda thinned firing strip proximally attached to the firing device for transferring the firing motion from said robotic system through the articulation joint. 11. A surgical instrument comprising: an implement portion responsive to firing motions from a robotic system communicating therewith and being diametrically dimensioned for endo-surgical use, the implement portion comprising:a first jaw including a first jaw slot;a second jaw including an elongated second jaw opening and wherein at least one of the first and second jaws is operably coupled to an elongated shaft that operably interfaces with said robotic system to apply closing motions generated by said robotic system to the implement portion to move one of the first and second jaws relative to the other one of the first and second jaws; anda firing device including a distally presented cutting edge longitudinally received between the first and second jaws, the firing device is configured to affirmatively space the first and second jaws relative to each other during longitudinal travel between the first and second jaws, the firing device further comprising:an upper member having a first upper surface and a first lower surface that longitudinally slidingly engage one of the first and second jaws;a lower pin including a second upper surface abutting the other one of the first and second jaws; anda middle pin including a second lower surface that slidingly engages the other one of the first and second jaws.
