A pusher element slidably mounted in the cartridge is provided for advancing the staples in the cartridge, for ejecting the staples from the cartridge and for forming the staples around the anvil. The surgical stapling instrument comprises a main body portion adapted for mounting the staple carrying cartridge, a thrust bar mounted to reciprocate in the main body portion for driving the pusher element forward to advance, eject and form the staples, a handle arrangement for receiving a manually applied force, and a linkage arrangement for directly transmitting the manually applied force to the thrust bar to advance the thrust bar and thereby advance, eject and form the staples.
