Abstract: An apparatus includes an elongate body, at least one latch member, and a cartridge removal feature. The elongate body is sized and shaped to correspond with a deck of a surgical staple cartridge such that the elongate body is configured to cover a plurality of staple apertures of the surgical staple cartridge. The at least one latch member is configured to removably secure the elongate body to the surgical staple cartridge. The cartridge removal feature is integral with the elongate body. The cartridge removal feature defines a gap that is configured to receive a portion of the surgical staple cartridge. The cartridge removal feature is further operable to remove the surgical staple cartridge from a surgical stapler.

Abstract: Surgical stapling instruments having surgical stapling cartridges are disclosed. At least one embodiment includes an end effector that has an elongate channel that is configured to operably support a surgical staple cartridge therein and an anvil that is movably supported on the elongate channel between an open position and closed positions in response to an application of opening and closing motions applied thereto. An anvil lock member cooperates with the anvil to retain the anvil in an open position when a staple cartridge has not been installed in the elongate channel and prevent the anvil from moving to a closed position until the staple cartridge has been seated within the elongate channel. Surgical staple cartridges are configured to move the anvil from an open position to an actuatable position when the cartridge has been installed in the end effector.

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. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

Abstract: A staple driver actuator for a surgical stapler includes a base having at least one bottom surface. The bottom surface defines a plane and is configured to slide longitudinally relative to a jaw of the surgical stapler. The staple driver actuator also includes a plurality of rails extending upwardly from the base. Each of the plurality of rails includes at least one cam surface, and each of the cam surfaces is inclined relative to the plane. The plurality of rails includes a laterally-opposed pair of outer rails and a laterally-opposed pair of inner rails. The staple driver actuator further includes a distal nose extending distally from at least a portion of the base and having at least one ledge surface. The ledge surface faces upwardly, is parallel to the plane, and is at least partially positioned distally relative to each of the outer and inner rails.
