Abstract
A skin stapler having a plurality of staples comprising a frame structure, with a nose section for directing the staple at a wound site, including a housing therein having an anvil, a staple ejector, a driver for deforming the staple about the anvil, and a staple follower for continually urging the staples against a release member. Means are also provided for actuating the driver in a substantially translatable direction; and the actuating means comprises a toggle mechanism. In addition, the stapler is provided with means for restoring the driver to its unactivated position, and means are provided for preventing the double loading of the staples in said surgical stapler. The skin stapler is lightweight and of the disposable type as it is generally small and relatively compact.
