摘要

An improved surgical stapler for simultaneously applying a plurality of surgical fasteners to body tissue, incorporating a flexible and resilient shield assembly comprising a substantially U-shaped wedge member mounted to and around the end of the anvil assembly, for separating extraneous body tissue from tissue to be fastened, and two shutter blades mounted on the sides of the wedge member for preventing extraneous body tissue from entering into the gap between the anvil assembly and fastener holder.
