Abstract: An end effector for use with a surgical stapler includes a staple cartridge assembly movable relative to an anvil assembly. The staple cartridge assembly defines a plurality of retention slots and a cavity. The staple cartridge assembly includes a plurality of staples, a plurality of pushers, an actuation sled, a surgical buttress material, a suture, and an anchoring button. The actuation sled is configured for movement along a length of the staple cartridge assembly to sequentially engage the plurality of pushers to eject the plurality of staples through the respective plurality of retention slots. The anchoring button is configured to be received in the cavity of the staple cartridge assembly such that a portion of the suture is supported in the cavity to be severed by a knife blade of the actuation sled when the actuation sled is advanced distally.

Abstract: A surgical buttress loading system includes an anvil having a spring assembly biased against a tissue facing surface of an anvil body and a loading tool including a cavity configured to receive the anvil therein, a buttress cartridge including a surgical buttress releasably disposed thereon, an actuator, and a handle operably coupled to the buttress cartridge. When the anvil is positioned within the cavity of the loading tool and the handle is moved to from an unactuated position to an actuated position, the handle moves the actuator to from a retracted position to an extended position and into engagement with the spring assembly of the anvil to lift the spring assembly off of the tissue facing surface and then slides the buttress cartridge towards the spring assembly to move a proximal end portion of the surgical buttress between the spring assembly and the tissue facing surface.

Abstract: A surgical stapling device includes a tool assembly having a drive assembly, an anvil, and a cartridge assembly. The cartridge assembly includes a replaceable staple cartridge that includes an actuation sled assembly having an actuation sled, a knife bar, and a retractor link. The retractor link is secured to the knife bar such that the actuation sled assembly is movable through a cartridge body of the staple cartridge. The retractor link is movable from a non-deformed condition disengaged from the drive assembly to a deformed condition engaged with the drive assembly to facilitate retraction of the actuation sled assembly after the stapling device is fired.

Abstract: A tool assembly for a surgical stapling device includes a first jaw supporting an anvil. A second jaw supports a staple cartridge. A drive member is movable from a retracted position towards an advanced position to move the second jaw in relation to the first jaw from an open position to a clamped position. At least two first pivoting links are operably coupled to a first side of the first and second jaws. At least two second pivoting links are operably coupled to a second side of the first and second jaws. The pivoting links each pivot in response to longitudinal advancement of the I-beam to move the second jaw between the open position and the clamped position. The second surface of the cartridge assembly is maintained in substantially parallel alignment with the first surface of the anvil as the second jaw is moved between the open position and the clamped position.
