Claim:
1. An instrument for positioning a fixation rod, comprising: an outer shaft including a lumen extending from a proximal end to a distal end and an elongated slot on the distal end; an inner shaft within the lumen; a roller rotatably coupled at an axis of rotation within the elongated slot on the distal end and configured to engage the fixation rod, the axis of rotation and the slot cooperating to allow the roller to translate as a whole distally and proximally from the fixation rod by moving the axis of rotation distally and proximally within the slot; a connecting rod linking a distal end of the inner shaft with an off-axis point of the roller, a pin coupling a proximal end of the connecting rod to the elongated slot; and an actuator operably coupled with the inner shaft to translate the inner shaft within the lumen and cause rotation of the roller to impart linear movement on the fixation rod.
