The tracheal hook can then be slid away from the device body with the hook's barbed tip entering the opening to enable the operator to easily and quickly secure the surgical airway. The design of the surgical device enables an economy of movements that otherwise would typically not be within the skill set of an operator who was not a surgeon.

Apparatus and methods for performing vasectomies are disclosed. In preferred embodiments, a clamp has a set of jaws, the distal ends of which terminate in a circular structure that is essentially a split ring. In certain embodiments, each jaw has a serrated edge that corresponds to serration on the opposite jaw, and each jaw is slightly less than a half-circle so that when closed there is a small slot or opening toward the handle side of the jaws. The jaws are adapted to grasp the vas of a patient and the slit permits a scalpel blade to cut the vas sheath longitudinally in the clamped region. Alternatively, the serrated jaws can be replaced by a single tooth on each arm of the clamp, and these teeth overlap, again leaving a single slot. Finally, in certain other embodiments, the distal ends are hooked structures and remain spaced apart even when the clamp is in the closed position.
