  • Patent number: 8245897
    Abstract: 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.

  • Patent number: 5188638
    Abstract: An anastomosis fastening technique wherein an annular fastener securing anvil is positioned over the end portion of a first hollow body organ to be joined to a second hollow body organ end or side portion and this first organ end is everted outwardly back over the anvil thereby forming a cuff. The anvil is provided with prepositioned and annularly disposed fastener securing devices on the exterior surface. The second hollow body organ and/or side portion is then positioned over the cuff of the first hollow body organ such that the intimal portions thereof to be anastomosed are in intimal coaptation. An anastomotic surgical fastener driving instrument with fastener cartridges therein, and which conforms in shape to the outer annular contours of the anvil is coaxially applied over the anvil with the organ portions positioned therebetween and the fastener driving instrument is then actuated to fasten the coaptating organ portions together. The organ portions to be anastomosed may first be tied down to the anvil.
