Abstract: A single use bone cutter comprised of a plate with a plurality of insert blade enclosures is described. The insert blade enclosures are arranged in a spiral pattern about the plate and are further positioned at varying height intervals through the thickness of the plate. The bone cutter provides a means whereby the insert blades can be easily positioned within the plurality of blade enclosures to provide a wide array of cutting diameters.

Abstract: A disposable reamer designed to improve bone and tissue removal efficiency is described. The reamer device comprises a reamer body shell, a series of reamer blades and a reamer shaft interface. The reamer body shell has a hemispherical structure having a concave interior surface and a convex outer surface. The series of reamer blades have a cutting portion comprised of a series of discrete cutting edges that is bent at an angle from the planar portion of the blade. The reamer blades are positioned along the curved concave interior surface of the hemispherical shell or along the curved convex outer surface of the shell. The reamer blades are positioned along the hemispherical shell such that their leading edges lie parallel to and tangent a bisecting plane.

Abstract: A single use bone cutter comprised of two concentric cylinders and a series of insert blades or cutter disc is described. The cutter blades or cutter disc is preferably positioned at the distal end of the cutter. The bone cutter also comprises a guide rod that aids in the line of sight when using the cutter device.

Abstract: An orthopedic cutting tool for reshaping the end of a femur is described. The cutting tool comprises three separate cutting blades that are positioned within different locations within a housing to reshape the end of the femur to thus receive a femur head prosthetic. The cutting tool forms the reshaped femur end in one cutting motion.

Abstract: A combined mode and temperature control valve for an HVAC housing includes a cylindrical sleeve rotatable within a stationary barrel. Hot or cold air enters lengthwise inlet slots in one side of the barrel located below or above a stationary dividing baffle in the housing. Air entering the barrel can exit to either a heater outlet, defroster outlet, or A/C outlet. The sleeve includes slots and openings which, when rotated continuously through a predetermined increment, open and close the hot and cold inlets in complementary fashion to allow in a full temperature range of hot or cold air, which mixes inside the hollow cylinder. The sleeve opens only one outlet at a time, blocking the other two, over the increment of rotation.
