Abstract
An abrader blade with integral depth control wings. The depth control wings which slide on a portion of the material being abraded to limit the depth of abrasion. The cutting surface of the abrasive surgical device is covered with abrading material. In a preferred embodiment tungsten carbide particles are brazed onto the blade substrate with an equal quantity of cobalt phosphorous braizing alloy. In this preferred embodiment an additional coating is added with a braze alloy specially developed for medical cutting. The carbide particles, the cobalt, the phosphorous and metal phosphides formed during the brazing process are all biocompatable. These blades are especially desirable for abrading bone material into particular shapes for interfacing with prosthesis parts. Several specific blades are disclosed.
