A surgical stapling instrument for forming and implanting surgical staples in the tissue of a patient to close a wound or incision therein. The instrument comprises a body. A row of staples is mounted within the body. A feeder assembly is provided to constantly urge the row of staples forwardly, to locate the forwardmost staple thereof in position to be formed. A pair of staple formers are pivotally mounted on the body and are rotatable between normal retracted positions and staple forming positions wherein they form the forwardmost staple of the row and implant the staple in the tissue of the patient. A pair of levers are pivotally affixed to the body of the surgical stapling instrument to shift the formers to their forming positions and a resilient member is provided to bias the formers to their normal retracted positions. |
