Abstract
An improved surgical stapler for closing wounds, having an approximation device connected to a side of the surgical stapler. The approximation device is a hook positioned adjacent the stapled ejection port and is adapted to grip one side of a wound and enable the operator to temporarily close the wound, while precisely positioning the staple ejection port over the closed wound. Subsequent actuation of the stapler causes the wound to be precisely stapled closed. In an alternative embodiment, the approximation device is integrally formed from one leg of a surgical staple, and provides an asymmetric staple configuration. The longer staple leg is designed with a hook end. When the stapler is partially actuated, the staple legs partially protrude from the staple ejection port, and the longer staple leg can engage the skin on one side of a wound, and enable the temporary closing of the wound for accurate positioning.
