The Graham Field-2684 and 2685 are professional-grade surgical instruments marketed under the Grafco brand. The Rankin-Kelly pattern combines the larger 6.25-inch size with jaws that are serrated only halfway down the length. This specific design allows for the secure clamping of larger blood vessels or tissue bundles while reducing the risk of trauma to the delicate structures caught in the non-serrated portion of the jaw. The straight 2684 model provides direct access for clamping, whereas the curved 2685 model is specifically designed to maneuver around obstacles and improve visibility in deeper surgical fields.
