1. In combination:
- a) an endoscopic staple mechanism comprising;
an elongated tubular shaft comprising an endoscopic section capable of emplacement within a cylindrical trocar tube during endoscopic surgery, said shaft formed as a cylinder and having a hollow interior and containing proximal and distal ends, and said shaft formed from a rigid construction;
an actuating mechanism attached to said shaft at said shaft proximal end;
a stack of staples arranged in a cartridge for sequential firing of a distalmost of said staples, said stack placed at the distal end of said shaft;
a firing mechanism including an anvil for forming staples, said anvil placed distal to said cartridge and said firing mechanism actuable by said actuating mechanism operating through said shaft; and
a transfer mechanism placed near the distalmost of said staples arranged in said cartridge, said transfer mechanism capable of transferring the distalmost of said staples to said firing mechanism, such that said actuating mechanism may cause said firing mechanism to form said staples; and
b) a cylindrical trocar tube into which is placed said staple mechanism, during endoscopic surgery.

Abstract
A unique hernia repair stapler is described which allows the forming of staples to attach prosthetics to tissue, or to approximate herniated tissue. The staple is useful in endoscopic operations and may be rotatable or stationary. The stapler has a unique forming and ejecting mechanism; as well, there is the availability of a loading mechanism useful for both cartridges and magazines of staples. An improved staple shape allows for better staple alignment, especially in a multiple load device.
