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 comprising a replaceable staple cartridge is disclosed. The staple cartridge comprises a longitudinal slot and three longitudinal rows of staple cavities defined alongside the longitudinal slot with staples removably stored therein. A double staple driver supports one staple from the first row and one staple from the second row. A single staple driver supports one staple from the third row. A sled comprises a first camming surface configured to contact the double driver, a second camming surface configured to contact the single driver, and a central portion movable through the longitudinal slot during a staple firing stroke. The first camming surface comprises a first width, and the central portion comprises a third width. The third width is greater than the first width. The firing member translates into a lockout recess when the sled is not in a proximal position prior to performing the staple firing stroke.
