A stapling apparatus for performing anastomosis on hollow organs. The apparatus consists of two combinable tools which are L-shaped, one tool for retaining staple retaining clips, and the other tool for retaining staples. The L-shaped tools are each provided with an elongated handle and a C-shaped jaw positioned at a distal bottom end of the handle in a plane substantially transverse to the handles of the tools. When the two tools are combined, the C-shaped jaw retaining a series of staple retaining clips is positioned below the C-shaped jaw retaining the arranged series of staples with the respective staples in registration with respective underlying clips for stapling. The C-shaped jaws provide gaps which permit ingress and egress of hollow organ ends to be stapled. A staple firing mechanism is operated from the proximal top end of one of the handles of the stapling apparatus whereby downward pressures is applied uniformly and simultaneously against the top of all staples to force them from their retaining sockets, through the hollow organ ends, and into stapling engagement with the respective underlying staple retaining clips.
