Abstract
Embodiments of the present invention are directed to devices, systems and associated methods for use in rod reduction and set screw insertion for a bone/spinal fixation system. In one embodiment of the invention, a device is provided for rod-reduction and set-screw insertion and may include a housing, a barrel provided with the housing and defining bifurcated end portions, an outer drive shaft slidably mounted on the barrel, a collar carried by the outer drive shaft for drawing the end portions of the barrel together as the collar is moved thereover, an inner drive shaft slidably and rotatably mounted within the outer drive shaft, a handle disposed at a an end of the outer drive shaft for effecting slidable and/or rotatable movement of at least one of the outer and inner drive shafts, a screw drive carried by the forward end of the inner drive shaft for engaging a set screw, a first lever actuated means for moving the outer drive shaft forwardly through the barrel in response to the squeezing of the first lever and a second lever for actuating a release mechanism for selectively allowing rearward movement of the outer drive shaft.
