Abstract
A surgical staple, particularly but not exclusively for use in endoscopic surgery, includes a first leg, a second leg, and a hinge portion joining the first leg and the second leg to one another. A spring element is connected between the first leg and the second leg biases the staple in a closed postfiring configuration. The staple is temporarily disposed in an open prefiring configuration in an access tube by a stalk holding the legs of the staple apart. A stapling operation includes manipulating the stalk to affix the staple to a soft substrate, and subsequently withdrawing the stalk to release the staple and allow the spring element to develop closing force in the legs. The spring element may be integral with the legs or a separate element connected thereto.
