Abstract: A reamer for use in minimally invasive hip replacement surgical approaches is provided. The reamer spindle includes an offset elongate housing portion that extends from a proximal housing end portion a distal housing end portion. A handle assembly, preferably comprising a durable lightweight material such as carbon fiber that is removably connectable to the housing of the reamer spindle. A reamer head is removably connectable to the distal neck portion and has a surface configured to cut bone.

Abstract: Disclosed is a surgical tool holder adapted to connect to a disposable cutting tool, and the surgical instrument combination. The tool holder has a shank with a quick tool coupling at one end and a drive adaptor at a second end. The coupling assembly has a coupling interface for holding the tool, and has a debris reservoir. A locking mechanism is engageable with the shank by a lock interface that holds the coupling assembly in functional assembly, and when unlocked allows component parts of the coupling assembly to be separated for cleaning and sterilization. The surgical tool has a flat base and complementary fittings adapted to be received by the holder's coupling interface. The combination of the flat base with the reservoir defines a relatively enclosed collection space to receive cutting debris from the tool while the holder and tool are coupled together.

Abstract: A reamer for use in minimally invasive hip replacement surgical approaches is provided. The reamer spindle includes an elongate housing portion that extends along a first axis and a neck or distal portion that extends along a second axis, wherein the second axis extends at an angle of between about 35 degrees and about 65 degrees relative to the first axis. A reamer head is removably connectable to the distal neck portion and has a surface configured to cut bone.
