Abstract
A surgical staple, particularly but not exclusively for use in endoscopic or laparoscopic surgery comprises a first leg provided with a first locking element, a second leg provided with a second locking element, and a hinge joining the first leg and the second leg to one another. The first locking element and the second locking element are designed to cooperate with one another to maintain the staple in a closed postfiring configuration. The staple is disposed in a closed prefiring configuration wherein at least one of the first leg, the second leg, the first locking element and the second locking element is deformed to prevent cooperation of the first locking element and the second locking element. The staple legs are provided with latching elements which cooperate with corresponding elements on a forceps jaws to enable a pivoting of the legs alternately away from and towards one another and about the hinge during a staple opening operation. Such latching elements may include loop-shaped eyelets or snap-lock projections such as knobs or cooperating snap-lock-type recesses.
