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