Abstract
The fascia stapler has a pistol-shaped housing from which two-piece clips can be ejected for closing an incision. The retainers for the clips and the straps for the clips are held in respective cartridges within the nose of the housing and can be ejected individually upon actuation of the stapler. A pusher assembly within the housing causes an individual strap to be expelled for passage through one end of a strap, piercing through the tissue and securement in the other end of the strap. Approximators with tissue engaging teeth are also used to bunch up the tissue about the incision during a stapling operation.
