摘要

An apparatus 10 is disclosed for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery. The apparatus includes a frame, and a generally elongated endoscopic section 14 connected to the frame and extending distally therefrom. A staple storage magazine 16 is provided for storing a plurality of surgical staples at the distal end portion of the endoscopic section with each staple being configured and adapted to attach the mesh to the body tissue. An elongated pusher system 24 formed of several assembled components and extending from the frame to the endoscopic section is provided for individually advancing at least one staple at a time distally for positioning adjacent the surgical mesh and the body tissue. The pusher system also includes a trigger mechanism 20 to actuate the pusher. Anvil means 88 provides for closing the staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to the body tissue. The distal portion can be pivoted up to 45 DEG in either or in both directions, or rotated with the endoscopic portion, under control from a collar on the proximal end of the endoscopic portion.
