ABSTRACT:
A surgical stapling apparatus is disclosed for suturing skin with deformable staples. The apparatus includes a pivoting anvil having a crescent-shaped configuration. The lower end of the anvil includes a forming lip which is disposed in the drive track of the apparatus. A driver blade is mounted for reciprocal movement in the drive track and includes a lower edge configured to cooperate with the forming lip to clinch the staple. An anvil release blade is disposed behind and coplanar with the driver blade in the drive track. The anvil release blade permits the release of the staple at any stage in the clinching operation. In use, upon downward actuation of the driver blade, the staple is clinched about the forming lip. To release the staple from the apparatus, the anvil release blade is lowered until an aperture located therein is aligned with an aperture provided in the driver blade thereby enabling the anvil to pivot, clearing the drive track. The subject stapling apparatus may be rapidly operated with one hand and is arranged to substantially prevent jamming.
