Abstract
A grasping forceps in the form of a rongeur having the teeth of its jaws displaced inwardly to create a rim between the outer edge of each jaw and its teeth which acts as a barrier for pushing the dura or tissue away from the teeth during the closing of the jaws. In other embodiments the barrier may take the form of guide members such as springs mounted to each jaw. In one such embodiment the guide members may comprise a guide member interconnecting the jaws at their distal end with guide members also interconnecting the jaws on each side of the jaws inwardly of the distal end. In a further variation each guide member may be mounted to a respective jaw peripherally around and outwardly of the jaw.
