    Abstract: An orthopedic reamer cutting tool is disclosed. The reamer is constructed having a hemispherical cutting shell that extends from an equatorial base to an apex. A plurality of cutting teeth, each having a primary tissue cutting surface, extend from the exterior surface of the cutting shell. A plurality of retractable blades, each having a secondary tissue cutting surface, are supported on a rotatable cam positioned at the base of the shell. Rotation of the cam in one of a clockwise or counterclockwise direction causes the retractable blades to extend through respective slits that extend through the thickness of the reamer shell. Rotation of the cam in the opposite direction causes the retractable blades to retract through the slits, back into the interior of the shell.

    Abstract: A bone cutter for use within the intramedullary canal is described. The bone cutter comprises a frusto-conical cutting head that extends to a barrel portion for attachment to a drive shaft. The cutting head comprises a plurality of spaced apart blades having a tissue cutting edge that extends radially from the exterior surface of the cutting head. The plurality of blades are arranged at prescribed angular relationships that are designed to increase cutting efficiency and debris removal, thereby reducing reactive torque, axial loading, and head pressure during a surgical procedure.

    Abstract: A torque limiting tool is described. The tool comprises a torque limiting mechanism comprising a sleeve connectable to a drive shaft and a torque drive coupler that resides within a housing. The sleeve comprises a sleeve annular sidewall having a plurality of outwardly projecting elongated first lobes and recessed first grooves that are circumferentially positioned along the length thereof. The drive coupler comprises a socket defined by a coupler annular sidewall having a plurality of outwardly projecting second elongated lobes and recessed second grooves positioned along the coupler interior sidewall. Torque is transferred therebetween when the ramped surfaces of the first and second lobes mate within respective second and first grooves of the coupler and sleeve. When a torque limit is exceeded, the first and second lobes of the sleeve and coupler disengage for their respective second and first grooves.

    Abstract: A cutting head for use with an intramedullary reamer is described. The reamer cutting head is of a unitary body construction that comprises a conically-shaped body having a bone cutting portion spaced from a barrel portion for attachment to a drive shaft. The bone cutting portion comprises a plurality of blades having a tissue cutting edge that outwardly extends from the cylindrical body. The plurality of blades is positioned about the cutting head in a spaced apart manner. The various plurality of blades are arranged at prescribed angular relationship that increases cutting efficiency and debris removal, thereby reducing reactive torque, axial loading, and head pressure during a surgical procedure.
