<p>A surgical stapling device having a removable staple cartridge (16) is disclosed. The cartridge includes a first opening (50C) and (50D) in the staple-forming end of the housing member (50) to allow access to a staple (64) and an aligned second opening (50G) to allow the lead staple to move therethrough. The staple cartridge also comprises a fixed blocking surface on the housing member and a traveling blocking surface on a feeder shoe (74). The traveling blocking surface is sized so that the feeder shoe moves relative to the fixed blocking surface while moving the staple. The feeder shoe is further haped so that, when the trigger member (12) is actuated when no staples remain in the staple cartridge, the staple former (44) is not blocked by the feeder shoe.</p> |
