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; and
a 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; and
a middle pin including a second lower surface that slidingly engages the elongate channel.

Abstract
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.

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; and a 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; and a middle pin including a second lower surface that slidingly engages the other one of the first and second jaws.
