  • Patent number: 4414974
    Abstract: A disposable, or one-time-use microsurgical knife has a slidable shroud that can be moved into a forward position to protect the blade, and can be moved rearwardly to allow use of the knife. The shroud, as well as other parts of the knife, are made of plastic, and a phosphorescent material is included to render the knife luminescent during steps taken in a darkened operating room. The extremely sharp razor chip blade includes a shank selectively wedged into the knife body so blades are interchangeable.
