Surgical fastener applying apparatus

A surgical fastener cartridge (100,200) is provided and includes a cartridge body (112) having a plurality of surgical fasteners (130) operatively disposed therein. An actuation mechanism (300) is housed within the cartridge body (112) and includes a plurality of pushers (150) operably associated with the plurality of surgical fasteners (130). The actuation mechanism (300) includes a plurality of pivotably connected link assemblies (302). Each link assembly (302) being pivotably engaged with a corresponding bottom surface (154) associated with each the pushers (150) and a corresponding top surface (164) associated with an internal channel housing (160) and operably coupled to one another. The actuation mechanism (300) includes an activation structure (350) configured to move each of the link assemblies (302) and sequentially cause each of the link assemblies (302) to move through a succession of motions within the cartridge body (112), such that the link assemblies (302) cause the corresponding pusher (150) to contact and, subsequently, sequentially eject the associated surgical fastener (130) towards the depression (91) in the anvil (90).
