Abstract
A surgical device for clamping body tissue between two movable members, for example a surgical stapling apparatus, includes a sheet of curved resilient material attached to one or both of the members for biasing the body tissue when the members are closed onto the tissue.
Claims24
A surgical device, which comprises:
- a) first and second elongated members movable between an open first position wherein said members are relatively spaced apart from each other and a closed second position wherein said members are relatively close to each other for clamping body tissue therebetween, said members having mutually facing surfaces;
- b) at least one sheet of resilient material attached to and covering at least a portion of said mutually facing surface of at least one of said members, said sheet of resilient material having a curved surface.
An apparatus for applying surgical fasteners to body tissue, which comprises:
- a) a cartridge for holding a plurality of surgical fasteners;
- b) an anvil having means for closure of surgical fasteners;
- c) means for moving said cartridge and said anvil between an open first position wherein said cartridge and said anvil are relatively spaced apart from each other and a closed second position wherein said cartridge and said anvil are relatively close to each other for clamping body tissue therebetween;
- d) means for driving said fasteners from said cartridge into said anvil for closure thereof;
- and
- e) a sheet of resilient material positioned between said cartridge and said anvil so that substantially all of the fasteners pass at least partially through said sheet of resilient material in response to firing of said apparatus wherein said sheet of resilient material has a curved surface.
