Abstract

An exemplary surgical apparatus may include a feeder belt configured as a continuous loop; staples fixed to and shearable from the continuous feeder belt; apertures defined in the continuous feeder belt; and a gear positioned at the distal end of the feeder belt within the continuous loop, where the gear engages at least one of the apertures to move the continuous feeder belt around the gear. Another exemplary surgical apparatus may include a feeder belt; a plurality of staples fixed to and shearable from the continuous feeder belt; and a plurality of teeth defined on the continuous feeder belt. Another exemplary surgical apparatus may include a continuous belt assembly that has a flexible rack with two ends, and a feeder belt with two ends, each end of the feeder belt connected to a corresponding end of the flexible rack; and staples fixed to and shearable from the continuous feeder belt.
