  • Surgical fastener apparatus
    Patent number: 5344060
    Abstract: An instrument for cutting body tissue and applying a plurality of two part surgical fasteners to the body tissue on each side of the cut. The instrument includes a U-shaped distal portion, and a body having a longitudinal portion for enclosing an axial drive means for pushing fasteners into position in the body tissue. The axial drive means is off-centered from the fastener pushing means in the fastener cartridge at the U-shaped distal portion. A trigger operated diverter is provided with a unique system of force conversion and transmission for converting a single off-centered axial drive force to a uniformly distributed drive force for pushing the fastener pushers, and the knife assembly.
