  • Patent number: 9848875
    Abstract: An anvil-attachable layer for use with a surgical stapler, or fastening instrument, wherein a proximal end portion of the layer is attached to a staple cartridge assembly, for example. The layer may be attached to the staple cartridge assembly by an adhesive, weld, or a staple-cartridge-based clamp, wherein the attachment is weak enough to allow the layer to pull away from the staple cartridge assembly with stapled tissue. Alternatively, the layer can include two or more lateral slits that define a connector region that can be cut by a knife of a surgical stapler to release the layer.

  • Patent number: 9737302
    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.

  • Patent number: 9693774
    Abstract: An apparatus comprises a body, a shaft assembly, an end effector, and an articulation joint. The end effector is operable to manipulate (e.g., staple) tissue. The articulation joint couples the end effector with the shaft assembly and permits the end effector to deflect away from the longitudinal axis of the shaft assembly. The articulation joint comprises a locking assembly, which is operable to selectively lock the angular position of the end effector relative to the longitudinal axis of the shaft assembly; and an unlocking feature. The unlocking feature is operable to selectively unlock the locking assembly. The shaft assembly further comprises a first movable member, which is operable to selectively drive articulation of the end effector at the articulation joint; and a second movable member, which is operable to selectively drive the unlocking feature. The second movable member is movable independently relative to the first movable member.
