An improved surgical stapler includes a stapler body having a driver and a magazine connected to the stapler body. The magazine includes a staple track for carrying a plurality of staples and an anvil associated with the staple track. The anvil has a staple forming surface for forming each of the staples thereon. A trigger is operatively connected to the driver for advancing the driver against the anvil so as to form the staple against the staple forming surface of the anvil. A feeder for feeding each of the staples from the staple track to the anvil is movably mounted in the magazine. A pinion is operatively connected to the trigger and is movably engaged with the feeder. An indexing member is movably engaged with the pinion such that the indexing member and the pinion advance the feeder and the staples toward the anvil upon an actuation of the trigger.read more
