SURGICAL FASTENER APPARATUS

摘要

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 34, and a body (10, 20) having a longitudinal portion (12, 22) for enclosing an axial drive means (180) for pushing fasteners (450) into position in the body tissue. The axial drive means is off-centered from the fastener pushing means in the fastener cartridge (330) at the U-shaped distal portion. A trigger operated (380) 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 pusher (410), and the knife assembly (440).
