A surgical stapling device includes tool assembly having an anvil and a cartridge assembly. The cartridge assembly includes a channel member that defines a cavity, a staple cartridge supported within the cavity of the channel member, and a biasing member. The staple cartridge supports staples, each having a back span and a pair of legs depending from the back span. The biasing member is positioned within the channel member and is deformable to allow the cartridge body to move vertically within the cavity of the channel member. The anvil incudes staple deforming pockets that are configured to deform the legs of the staples from a position within the same plane as the back span to positions laterally offset from the back span.

Embodiments include an end effector including an anvil, the anvil having an anvil face, an anvil blade channel defined by the anvil face, a first pocket row of first row staple pockets, a second pocket row of second row staple pockets, a third pocket row of third row staple pockets, a fourth pocket row of fourth row staple pockets, a fifth pocket row of fifth row staple pockets, a sixth pocket row of sixth row staple pockets, a cartridge having a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples, and a blade, the blade having a cutting edge, where the blade is movable from a first position at a distal end of the cartridge to a second position at a proximal end of the cartridge.

A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

A surgical stapling device includes a staple reload and a shipping wedge. In embodiments, the shipping wedge is configured to disable the use of a staple reload if the staple reload does not have an actuation sled. In other embodiments, the actuation sled includes a readable identifier that facilitates confirmation of the presence of an actuation sled within a staple reload from a location externally of the staple reload.

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 base also has at least one top surface parallel to the plane. The staple driver actuator further includes at least one rail extending upwardly from the base. The rail includes at least one first cam surface. The first cam surface is inclined relative to the plane, and the first cam surface is longitudinally aligned with at least a portion of the at least one top surface.

Devices, systems and/or methods for repairing soft tissue adjacent a soft tissue repair site. In one embodiment, the repair device includes an anchor member having a base with at least four legs extending from the base. The base extends with a generally flat circular profile defining an upper surface and an underside surface with a central opening extending therethrough. Further, the at least four legs extend from the base with an elongated angled portion, the elongated angled portion being oriented at an angle less than seventy-five degrees relative to the underside surface of the base. With this arrangement, the anchor member may be fixated to soft tissue by rotating the base with a delivery tool so that the elongated angled portion of the at least four legs facilitates the anchor member sinking into the soft tissue and fixating thereto.

A surgical stapling instrument includes a releasable stapling end effector. The stapling end effector includes a body portion, a jaw assembly pivotally secured to the body portion, and an articulation mechanism extending between the body portion and the jaw assembly. The jaw assembly is articulable between a non-articulated position and at least one articulated position. The articulation mechanism includes a barrel member and first and second linkage assemblies. The barrel member defines a channel and each of the first and second linkage assemblies include a protrusion received within the channel. Rotation of the barrel member in a first direction causes the first linkage assembly to move in a proximal direction and the second linkage assembly to move in a distal direction to cause the jaw assembly to move from the non-articulated position to the at least one articulated position.

A stapling device includes an adapter assembly and a reload assembly that includes a reload release mechanism that is movable from a locked position in which the reload assembly is locked onto the adapter assembly to an unlocked position in which the reload assembly can be removed from the adapter assembly. The adapter assembly of the stapling device includes a lockout that prevents movement of the reload release mechanism to the unlocked position unless the stapling device is in a non-articulated, unfired position.

A surgical system comprising an electric motor and a surgical instrument is disclosed. The surgical instrument comprises a housing, a shaft extending from the housing, a fastener cartridge, an anvil, a translatable drive member, and a rotatable actuator knob. The housing comprises an input shaft operably coupled to the electric motor. The input shaft is rotatable in a first mode by the electric motor. The fastener cartridge comprises a plurality of fasteners removably stored therein. The anvil is configured to deform the fasteners. The translatable drive member is configured to move the anvil toward and away from the fastener cartridge. The translatable drive member is movable by the electric motor in the first mode. The rotatable actuator knob is configured to be rotated multiple full rotations in a second mode to manually cause the input shaft to move the anvil.

A surgical stapling apparatus includes a loading unit and a surgical buttress assembly. The loading unit includes an anvil assembly and a staple cartridge assembly. The staple cartridge assembly includes a staple cartridge having a tissue facing surface including staple pockets and a central longitudinal slot defined therethrough and a hook assembly extending outwardly from the tissue facing surface. The surgical buttress assembly includes an anvil buttress and a cartridge buttress. Each of the anvil and cartridge buttresses includes a body, a proximal tab, and a distal tab. The anvil and cartridge buttresses are interconnected at a junction of the proximal tabs and the surgical buttress assembly is folded at the junction such that the proximal tabs substantially overlie one another. The proximal tabs are engaged with the hook assembly to releasably secure the proximal tabs of the anvil and cartridge buttresses to the staple cartridge assembly.
