Claim Text:
1. A rod reducer for the reduction of spinal rods into a rod-receiving portion of a fixation anchor, comprising: an outer sleeve including a cylindrical housing and a pair of anchor coupling arms extending distally from the cylindrical housing, the anchor coupling arms each including an engagement feature configured to releasably couple an arm of a fixation anchor, the coupling arms being spaced apart to define a rod channel therebetween; an inner shaft including a distal rod engagement feature that advances distally relative to the coupling arms, the inner shaft being coupled to the outer sleeve via a coupler that drives distal advancement of the distal rod engagement feature via a first threaded advancement mechanism and a second non-threaded advancement mechanism, the coupler including an internally threaded ring and a latch plate locking feature having a front plate and a rear plate connected to each other by first and second side connectors that couple the latch plate to the ring, when engaged the latch plate inhibits proximal advancement of the distal rod engagement feature via the second non-threaded advancement mechanism but does not inhibit distal advancement of the distal rod engagement feature via the second non-threaded advancement mechanism, the first and second side connectors being coupled to the ring such that the latch plate is fixed both rotationally and longitudinally relative to the ring but slides relative to the ring to engage and disengage the latch plate locking feature.
