A surgical stapling device particularly suited for endoscopic procedures is described. The device includes a handle assembly and an elongated body extending distally from the handle assembly. The distal end of the elongated body is adapted to engage a disposable loading unit. A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body. A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device.

1. A surgical unit having a proximal portion arranged for connection to an elongate body having a drive member, the unit having an axial drive assembly with a drive beam,the unit having jaw members having an open and a closed position,one of the jaw members having a staple cartridge and the other of the jaw members having an anvil portion, the surgical unit being detachably engageable with the elongate body,the jaw members being mounted for articulation and being pivotal from a position aligned with a longitudinal axis of the elongate body to a position misaligned with the longitudinal axis of the elongate body, andan articulation mechanism including an articulation link offset from the longitudinal axis and having a distal end secured to the jaw members and a proximal end including a hook portion, the articulation link being movable upon attachment to the elongate body to effect articulation of the jaw members,wherein the staple cartridge has staple pushers, each staple pusher driving three staples. 2. The surgical unit of claim 1, wherein the drive beam includes a distal working head. 3. The surgical unit of claim 2, wherein the drive beam has a proximal engagement section for connection with the drive member. 4. The surgical unit of claim 1, wherein the drive beam is constructed from at least one sheet of material. 5. The surgical unit of claim 1, wherein the drive beam has a vertical portion with a knife. 6. The surgical unit of claim 1, wherein the proximal portion has nubs to form a bayonet type coupling. 7. The surgical unit of claim 1, wherein the staple cartridge includes retention slots for receiving a plurality of fasteners. 8. The surgical unit of claim 7, wherein the unit includes pushers arranged with the retention slots and fasteners. 9. The surgical unit of claim 1, wherein the unit includes an actuation sled with cam wedges. 10. The surgical unit of claim 1, wherein the staple cartridge has a central longitudinal slot to facilitate passage of a knife blade. 11. The surgical unit of claim 1, wherein the anvil portion has a plurality of staple deforming concavities. 12. The surgical unit of claim 1, wherein the anvil portion has a longitudinal slot to facilitate passage of the drive beam. 13. The surgical unit of claim 1, wherein the anvil portion has a camming surface for engagement by the drive beam. 14. The surgical unit of claim 1, wherein the unit has a mounting assembly pivotally secured to a housing portion for mounting the jaw members for pivotal movement. 15. The surgical unit of claim 1, wherein the staple cartridge defines three staggered rows of staple retaining slots. 16. The surgical unit of claim 15, wherein the staple cartridge defines three staggered rows of staple retaining slots on one side of a knife slot, and three staggered rows of staple retaining slots on another side of a knife slot.
