Abstract: A surgical clamp includes a clamp head, and a first jaw and a second jaw, each mounted to the clamp head for movement toward and away from each other. The clamp also includes an operative mechanism coupled to the proximal end of at least one of the first jaw and the second jaw, and an actuating structure connected to the operative mechanism for imparting a parallel opening movement to at least one of the first jaw and the second jaw from a first position to a second position where the first jaw and the second jaw are spaced apart and parallel to one another, the actuating structure selectively imparting further scissors-like opening movement to at least one of the first jaw and the second jaw from the second position to a third position where the first jaw and the second jaw are spaced apart a distance greater than that of the second position.
