Abstract
An apparatus 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 connected to the frame and extending distally therefrom. A staple storage magazine 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 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 mecanism to actuate the pusher. Anvil means 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 invention also relates to a system for attaching surgical mesh to body tissue, a method for endoscopically attaching surgical mesh to body tissue. The staple for endoscopically attaching the surgical mesh to body tissue and a kit for accomplishing such attachment.
