Abstract
Sternal clamping devices have a pair of opposed generally J-shaped clamp members which are laterally adjustable relatively to one another but can be rigidly joined via a set of machine screws. Preferably, the machine screws are of a taper-headed variety which seat within a conformably shaped countersunk region of one of the clamp members so as to present a substantially flush upper surface. The machine screws are, however, of sufficient length so as to be coupled threadingly with a respective threaded aperture formed in the other clamp member. The threaded coupling of the set screws with the other clamp member will thus rigidly unite the pair of clamp members one to another without lateral shifting occurring over time. Also, the clamp members may be rapidly disassembled and separated from one another (e.g., in case of a medical emergency requiring the surgeon to have quick access to the patient's thoracic cavity) by simply removing the set of screws therefrom.
