Abstract
An instrument and method for locating and attaching a spinal coupler to an implanted spinal rod including body and lever handles that attach about the spinal rod. A cam handle is connected to the body handle to actuate a plunger that applies a compression force to the spinal coupler to attach it to the spinal rod by an interference fit. The body and lever handles each include a forked jaw having legs that attach to the spinal rod on each side of the spinal coupler. In one embodiment, the plunger includes a control knob to vary the instrument actuating force and prevent over extension of the plunger.
