Abstract: An orthopedic reamer cutting tool is disclosed that incorporates a second material such as graphene having an increased coefficient of thermal conductivity to remove heat generated at the tissue cutting surface during use. The reamer is constructed having a hemispherical cutting shell that extends from an equatorial base to an apex at a distal end. A plurality of cutting teeth, each having a tissue cutting surface, extend from the exterior of the cutting shell. A reamer driver interface may be positioned spanning the diameter of the reamer base. The second material, having increased thermal conductivity, may be applied to the interior and/or exterior shell surfaces. In addition, the second material may be incorporated within the shell or the driver interface.

Abstract: An orthopedic impactor device for positioning an orthopedic prosthetic cup implant during a hip replacement surgery is described. The impactor comprises a distal prosthetic cup engagement portion which is separated from a proximal strike plate by an elongated housing and handle. The housing has a length that extends from a proximal housing portion to a distal housing end with an intermediate housing section therebetween. The intermediate housing section comprises spaced right and left side walls that extend upwardly from a bottom wall to an upper opening. A drive train, comprising a connection rod connectable to an orthopedic prosthetic cup, at least partially resides within the elongated housing. The drive train comprises a linkage sub-assembly that transfers rotational movement of a shaft located at the drive shaft proximal end to the connection rod.
