<p>A surgical blade includes an elongate outer tubular member and an elongate inner member movably received within the outer member. The inner member has a distal cutter positionable adjacent a distal opening in the outer member. A coating of copper or alloys or mixtures of copper and one or more other elements is on a portion of the outer surface of the inner member, the inner surface of the outer member, or both. The outer and inner members are formed from stainless steel, e.g., soft stainless steel. A method of cutting tissue, e.g., hard tissue such as bone, includes providing a surgical blade having an inner member and/or an outer member coated with copper or alloys or mixtures of copper and one or more other elements, placing the surgical blade against the tissue, and driving the inner member to cut the tissue.</p> |
