    Abstract: Embodiments of a surgical instrument and its methods of use are disclosed. The disclosed embodiments of a surgical instrument may include a handle and an elongated shaft assembly distally extending from the handle. The elongated shaft assembly may include an articulable portion. An articulation control may be associated with the elongated shaft assembly. The articulation control may be movable between a first position in which the elongated shaft assembly is arranged in a first articulation position and a second position in which the elongated shaft assembly is arranged in a second articulation position. The surgical instrument may include a fastener deployment system with a locking member. The articulation control may block movement of the locking member when the articulation control is located in the first position. The articulation control may also permit movement of the locking member when the articulation control is located in the second position.

    Abstract: Articulating surgical instruments are disclosed. In one embodiment, a surgical instrument may include an elongated shaft assembly including an articulable portion moveable between a non-articulated configuration and an articulated configuration. First and second articulating shafts of the elongated shaft assembly may be coaxially arranged and axially fixed at an attachment point located distally from the articulable portion. Proximal portions of the first and second articulating shafts may be displaceable in opposing directions to articulate the articulable portion from the non-articulated configuration to the articulated configuration. In another embodiment, an articulation control may be movable from a first position to a second position to move an articulation lock from a locked configuration to an unlocked configuration to selectively permit articulation of a surgical instrument. The articulation lock also may be movable from the second position to a third position to articulate the surgical instrument.

    Abstract: Surgical fasteners for use with articulating surgical instruments are disclosed. In one embodiment, a surgical fastener may include a head, a shaft extending distally from the head, and a through bore extending through the shaft from a proximal surface of the head to a distal end of the shaft. A fastener carrier of a surgical instrument may be slidably received in the through bore, and the through bore may be sized and shaped to have two or fewer contact points with the fastener carrier when the fastener carrier is in a fully articulated configuration. In another embodiment, a fastener may include a head, a shaft extending distally from the head and including a distal tip, a sloped surface sloping toward the distal tip, and a through bore passing through the head, shaft, and sloped surface. The sloped surface may terminate at two shoulders located on opposing sides of the through bore.

    Abstract: A surgical instrument including a power assist device, and its method of use for deploying surgical fasteners, is disclosed. The surgical instrument may include a handle, an elongated shaft extending from the handle, and a surgical fastener deployment system including a driveshaft. The driveshaft is actuatable between at least a first proximal position and a second distal position. A striker is movable relative to the driveshaft and an impact surface is associated with the driveshaft. The impact surface is constructed and arranged to be struck by the striker member to displace the driveshaft to the second distal position and deploy the surgical fastener.

    Abstract: Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft assembly extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft assembly including a reciprocating driveshaft disposed within the elongated shaft assembly. The driveshaft may include an internal channel and at least one guide surface shaped and arranged to maintain an orientation of at least one fastener in the channel of the driveshaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft assembly for displacing one or more fasteners within the elongated shaft assembly towards a distal fastener deployment position.
