Abstract: A surgical device includes an outer member, an inner member, and at least one locking element. The inner member is at least partially supported within the outer member. The at least one locking element is configured in a first arrangement of the surgical device to lock the inner member in a first position and configured in a second arrangement of the surgical device to unlock the inner member from the first position. The at least one locking element is configured to change from the first arrangement to the second arrangement upon coupling the inner member in an operational arrangement to a hand piece.

Abstract: A surgical instrument. Example surgical instruments include a cutting member being at least partially positioned within the outer member. A drive member coupled to the cutting member such that in response to only a rotational force applied to the drive member in a single direction, the cutting member (i) rotates and (ii) moves linearly in a back-and-forth motion. The drive member having a continuous helical groove including a first helical channel and a second helical channel that are blended at their ends. The first helical channel having a first helical angle that causes the cutting member to move in a first direction at a first linear speed and the second helical channel having a second helical angle that is smaller than the first helical angle that causes the cutting member to move in a second opposing direction at a second linear speed that is slower than the first linear speed.

Abstract: 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.
