Apparatus is disclosed for applying surgical fasteners to body tissue along an arcuate path. Each surgical fastener may be in the form of a two-part fastener having a pronged fastener portion for piercing body tissue, and an apertured retainer dimensioned and configured for engaged reception of the pronged fastener portion in interference fit therewith for gripping the body tissue therebetween. Alternatively, the fasteners may be in the form of deformable staples. The apparatus preferably includes arcuately shaped means for holding a plurality of the fastener portions in generally aligned relation, correspondingly arcuately shaped means spaced from the fastener portion holding means for gripping body tissue therebetween and for releasably holding a plurality of the retainers in generally aligned relation and positioned opposite the fasteners when the body tissue is positioned therebetween. Means is provided for sequentially advancing the pronged fastener portions toward the apertured retainers to cause the fastener portions to pierce the body tissue and to be received within the apertures of the retainers in engaged interference relation so as to cause the fastener portions and the retainers to be engaged while gripping the body tissue therebetween. A knife may be provided to cut the body tissue adjacent the fasteners as the fasteners are applied. A method for applying fasteners to body tissue on the apparatus of the invention along an arcuate path is also disclosed.
Apparatus for applying a plurality of rows of fasteners to body tissue which comprises a first member having a fastener cartridge for supporting at least two rows of fasteners and a second member disposed opposite said first member, said first and second members adapted to be assembled in a manner t
Apparatus for applying a plurality of rows of fasteners to body tissue which comprises a first member having a fastener cartridge for supporting at least two rows of fasteners and a second member disposed opposite said first member, said first and second members adapted to be assembled in a manner to position body tissue between said cartridge and said second member, means adapted to be advanced distally to sequentially drive said fasteners into the body tissue toward said second member, knife means including a knife bar and a cutting edge at a distal end thereof and movable between a proximal position and a distal position to cut body tissue between said at least two rows of fasteners when said fasteners are driven into the body tissue, and means for contacting said knife bar to block movement thereof to said distal position after advancement of said knife bar to cut tissue and subsequent retraction to said proximal position.
