Abstract: An orthopedic bone cutter for cutting bone and tissue is described. The orthopedic bone cutter comprises a cutting shell and a cutting insert that resides within an opening that extends through the apex region of the shell. A pin and slot mechanism positioned within the shell interior provides for independent axial and rotational movement of the insert within the shell. The shell comprises a partially hemispherical structure having a plurality outwardly extending and spaced apart shell cutting teeth. The insert comprises an annular sidewall that meets an end wall having a plurality of outwardly extending and spaced apart insert teeth. With the insert at a retracted position within the shell, the bone cutter is rotated in a first direction to cause the shell cutting teeth to cut, for example, an acetabular roof and labrum. Then, rotation of the shell in a second opposite direction causes the shell to stop cutting, but provides for the insert to extend outwardly to cut the acetabular floor and fossa.

Abstract: An orthopedic bone cutter for cutting bone and tissue is described. The cutting device comprises a plurality of radially extending struts that form a frame to which a base is connected thereto. Each of the struts that form the frame comprise sidewalls having left and right sidewall portions that are positioned at an angular relationship with respect to a primary strut sidewall portion. A plurality of cutting teeth reside along each of the struts have a tissue cutting surface that is raised above the exterior strut surface. The base of the orthopedic bone cutter may comprise a cross bar or bar and boss interface which secure bone cutter to a drive shaft.

Abstract: An orthopedic bone cutter for cutting bone and tissue is described. The cutting device comprises a support frame having a plurality of radially extending struts to which a cutting shell is removably connected thereto. The frame serves as a universal support structure that provides added mechanical support and stability to which various embodiments of cutting shells may be connected thereto. The bone cutter of the present invention is designed such that the cutting shell may comprise a variety of embodiments that enable the removal of bone and tissue. Embodiments of the cutting shell may comprise at least a partially hemispherical shape in which a plurality of cutting surfaces may extend. In addition, the cutting shell may comprise a plurality of removal cutting blade inserts that are received within slots that extend through the shell thickness.

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.

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.
