Abstract
A surgical stapling instrument can comprise a jaw configured to receive a staple cartridge, a plurality of staple drivers positioned within the jaw configured to eject staples from the staple cartridge, and a firing member configured to engage the staple drivers as the firing member is advanced from an unfired position to a fired position. As the firing member is advanced from its unfired position, the firing member can lift the staple drivers upwardly within a cartridge body of the staple cartridge. When the firing member is returned to its unfired position, the firing member can lower the staple drivers downwardly within the cartridge body thereby resetting the staple drivers prior to a new staple cartridge being positioned within the jaw.
