Abstract: A spine retractor provides lateral access to the spine for distracting soft tissue and psoas muscle for spinal fusion procedures utilizing position controllable blades. The retractor allows concerted linear distraction of two lateral blades and separate linear distraction of one medial blade. Individual angulation assemblies associated with each blade provides separately controllable angulation. Handles attached to the two lateral blades control their distraction while a medial knob controls medial blade distraction. An expansion knob associated with each handle provides individually precise distraction of its associated blade. Each angulation assembly comprises an angulation knob that threads into a distal arm of a blade holder assembly and is received into a spherical ball seated in a spherical pocket in a mating proximal arm of the blade holder assembly. Torque applied to the spherical ball by the angulation knob causes distal arm angulation relative to the proximal.

Abstract: 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.
