1. A stapling device comprising:
a frame defining a longitudinal axis, the frame including a distal transverse portion, a proximal transverse portion, and a central longitudinal portion extending between the distal and proximal transverse portions, the distal transverse portion of the frame defining a channel;
an approximation assembly supported on the frame, the approximation assembly including a clamp slide assembly having a distal portion defining a pocket, the clamp slide assembly movable in relation to the frame from a retracted position to an advanced position;
an anvil fixedly secured to the distal transverse portion of the frame over the channel, the anvil and the channel defining a channel inlet; and
a reload assembly including a cartridge assembly with a pusher and a cutting plate removal pin engageable with the pusher, and a cutting plate supported on the cartridge assembly, the reload assembly being removably supported on the stapling device to position the cartridge assembly in the pocket of the clamp slide assembly and to position the cutting plate in the channel of the distal transverse portion of the frame;
with the pusher being movable longitudinally from a retracted position to an advanced position for ejecting staples, and with the cutting plate removal pin being movable longitudinally for engagement with the cutting plate;
wherein the pusher is positioned to engage the cutting plate removal pin as the pusher is moved from its retracted position to its advanced position to move the cutting plate removal pin from its retracted position to its advanced position.
