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.

1. A stapling assembly, comprising: a staple cartridge, comprising: a channel;a cartridge body positioned in said channel; anda plurality of staples removably stored in said cartridge body;a sled stored in an unfired position, wherein said sled is configured to slide under said staples and eject said staples from said cartridge body during a staple firing stroke;an anvil configured to deform said staples;a firing member configured to advance said sled through said staple firing stroke, wherein said firing member is configured to engage said anvil and said staple cartridge and hold said anvil and said staple cartridge relative to one another during said staple firing stroke; anda restraining member,wherein said stapling assembly is in an unlocked condition when said sled is in said unfired position, and wherein said restraining member does not stop said staple firing stroke when said stapling assembly is in said unlocked condition, andwherein said stapling assembly is in a locked out condition when said sled is not in said unfired position and said staple firing stroke is initiated, and wherein said restraining member stops said staple firing stroke when said stapling assembly is in said locked out condition. 2. The stapling assembly of claim 1, wherein said restraining member is in said channel. 3. The stapling assembly of claim 1, wherein said cartridge body is replaceable and removable from said channel. 4. The stapling assembly of claim 1, wherein said firing member further comprises a cutting edge, and wherein said restraining member is configured to engage said firing member laterally with respect to said cutting edge. 5. The stapling assembly of claim 1, further comprising biasing means for placing said restraining member in the path of said firing member. 6. A stapling assembly, comprising: a staple cartridge, comprising: a channel;a cartridge body positioned in said channel; anda plurality of staples removably stored in said cartridge body;a sled stored in an unfired position, wherein said sled is configured to slide under said staples and eject said staples from said cartridge body during a staple firing stroke;an anvil configured to deform said staples;a firing member configured to move through a longitudinal path to advance said sled through said staple firing stroke, wherein said firing member is configured to engage said anvil and said staple cartridge and hold said anvil and said staple cartridge relative to one another during said staple firing stroke; anda restraining member extending laterally to said longitudinal path,wherein said stapling assembly is in an unlocked condition when said sled is in said unfired position, and wherein said restraining member does not stop said firing member from moving along said longitudinal path when said stapling assembly is in said unlocked condition, andwherein said stapling assembly is in a locked out condition when said sled is not in said unfired position prior to said staple firing stroke, and wherein said restraining member stops said firing member from moving along said longitudinal path when said stapling assembly is in said locked out condition. 7. The stapling assembly of claim 6, wherein said restraining member is in said channel. 8. The stapling assembly of claim 6, wherein said cartridge body is replaceable and removable from said channel. 9. The stapling assembly of claim 6, wherein said firing member further comprises a cutting edge, and wherein said restraining member is configured to engage said firing member laterally with respect to said cutting edge. 10. The stapling assembly of claim 6, further comprising biasing means for placing said restraining member in the path of said firing member. 11. A stapling assembly, comprising: a staple cartridge, comprising: a channel;a cartridge body positioned in said channel; anda plurality of staples removably stored in said cartridge body;a sled stored in an unfired position, wherein said sled is configured to slide under said staples and eject said staples from said cartridge body during a staple firing stroke;an anvil configured to deform said staples;a firing member configured to advance said sled through said staple firing stroke, wherein said firing member is configured to engage said anvil and said staple cartridge and hold said anvil and said staple cartridge relative to one another during said staple firing stroke, and wherein said firing member comprises a cutting edge configured to incise the tissue of a patient during said staple firing stroke; anda restraining member extending laterally to said cutting edge,wherein said stapling assembly is in a ready-to-be-fired condition when said sled is in said unfired position, and wherein said restraining member does not impede said staple firing stroke when said stapling assembly is in said ready-to-be-fired condition, andwherein said stapling assembly is in a locked out condition when said sled is not in said unfired position upon the initiation of said staple firing stroke, and wherein said restraining member is configured to engage said firing member laterally with respect to said cutting edge when said stapling assembly is in said locked out condition. 12. The stapling assembly of claim 11, wherein said restraining member is in said channel. 13. The stapling assembly of claim 11, wherein said cartridge body is replaceable and removable from said channel. 14. The stapling assembly of claim 11, further comprising biasing means for placing said restraining member in the path of said firing member.
