    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 surgical instrument is disclosed. The surgical instrument can include a first jaw, a second jaw, and a jaw closure lockout system. The first jaw can comprise a pivot pin slot and a slide pin slot. The second jaw can comprise an anvil and, in addition, a mounting portion comprising a pivot pin, which can be movably positioned in the pivot pin slot. A shiftable guide can be movably positioned in the first jaw and can comprise a body and a barrier wall. The body can comprise a slide pin movably positioned in the slide pin slot. The barrier wall can be aligned with a portion of the pivot pin slot when the slide pin is positioned within a range of positions in the slide pin slot, and the barrier wall can be offset from the pivot pin slot when the slide pin is positioned outside the range of positions.
