FLEXIBLE DRIVE SHAFT ASSEMBLY AND METHODS
Illustrative methods of manufacturing flexible drive shaft assemblies for preparing bone can include steps such as providing, receiving or manufacturing a mold. Injecting a first polymeric material into the mold to form a coupling member, the coupling member adapted for attachment to a torque-providing driving tool. Injecting a second polymeric material into the mold to form a work member, the work member adapted to interface with the bone to prepare the bone. The method can further include injecting a third polymeric material into the mold in an overmolding process to form a flexible shaft extending from the coupling member to the work member. The assemblies resulting from such methods can include a flexible shaft that is adapted to transmit a majority of a torque received from a torque-providing driving tool through the flexible shaft. In some examples, the flexible shaft can include a solid polymeric shaft.
