Abstract

One exemplary surgical apparatus may include at least one carrier, staples fixed to a corresponding carrier, and a feeder belt to which at least one carrier is frangibly connected. Another exemplary surgical apparatus may include a staple holder, an anvil movably connected to the staple holder, a feeder belt, where at least part of the feeder belt extends into the staple holder, and staples fixed to and frangibly separable from the feeder belt; where the staples are organized into at least two groups spaced apart from one another; and where at least one staple is deployable to a different closed shape than at least one other staple. Another exemplary surgical apparatus may include a feeder belt, a first plurality of staples fixed directly to and frangibly separable from the feeder belt; a plurality of extension arms extending at least partially in the lateral direction away from the feeder belt; and a second plurality of staples each fixed to an extension arm at a location spaced laterally apart from the feeder belt.

Claims

1. A surgical apparatus, comprising:

a staple holder;

a knife movable generally longitudinally along said staple holder;

at least two feeder belts located on each side of said knife;

wherein one said feeder belt on one side of said knife includes two rows of said staples extending therefrom, and wherein another said feeder belt on the same side of said knife includes only one row of said staples extending therefrom; and

a plurality of staples fixed to and frangibly separable from each said feeder belt.

2. The surgical apparatus of claim 1, wherein at least two said feeder belts on one side of said knife are fixed to one another.

3. The surgical apparatus of claim 1, further comprising a master belt to which at least two said feeder belts are fixed.

4. The surgical apparatus of claim 1, wherein a first said feeder belt includes a plurality of apertures defined therethrough, and wherein a second said feeder belt is fixed to an upper surface of said first feeder belt such that at least one said staple of said second feeder belt extends through a corresponding said aperture in said first feeder belt.
