Abstract:
This disclosure describes example embodiments of rod reduction instrumentation and other rod and vertebrae manipulation instruments. The rod reducers can be used during the installation of a rod based surgical fixation system to help urge the rod into the fixation anchors. The reducers described provide various configurations delivering large reduction distance capabilities, strong controlled reduction coupled with an ability to quickly advance the reducer if desired, and reduction of bulk through the surgical corridor.

Claim (Index 14):
A system to facilitate seating of a spinal rod into a rod-receiving portion of a fixation anchor, comprising:\n a rod reducer having a translation unit and a coupling unit, the coupling unit comprising: an elongated, generally tubular base member with a proximal, central, and distal portion, a lumen extending longitudinally therethrough, a pair of multi-pitch helical grooves arranged on opposites sides of the central portion of the base member, a pair of longitudinal recesses positioned on opposite sides of the base member and extending from the central portion to the distal portion, the longitudinal recesses including a displacement pin, and a pair of anchor coupling arms located at the distal end of the base member, the coupling arms being spaced apart to define a cavity and a rod channel therebetween; a lock mechanism comprising a drive knob located between the central portion and proximal portion of the base member, wherein the drive knob is generally cylindrical with a lumen therethrough, sized and configured to slideably receive the base member therein and allow rotation of the knob relative to the base member, the drive knob having a groove along a distal edge of an interior surface and a pair of apertures on opposite sides of the knob, each with a drive pin passing therethrough and into the lumen of the drive knob to engage the helical grooves of the base member; a pair of attachment arms extending from the central portion to the distal portion of the base member and positioned within the longitudinal recesses, the attachment arms including an anchor engagement feature at a distal end that engages complementary engagement features on the rod receiving portion of the fixation anchor, the attachment arms each including an angled recess that engages with the displacement pin of each longitudinal recess, the attachment arms also including a tab at a proximal end that engages the groove of the drive knob, wherein rotation of the drive knob results in translation of the attachment arms; the translation unit including a distal rod engagement end that advances in a distal direction relative to the coupling arms, the distal rod engagement end being coupled to a translating mechanism that drives the distal advancement of the distal rod engagement end.
