Abstract
In one form, a tool apparatus is provided that permits a spinal rod and cap assembly to be secured into a yoke coupling member anchored into a spinal bone. The tool apparatus includes a single actuator handle that is operable to both advance a drive member or persuader rod linearly along a longitudinal axis of the tool and also to rotate the drive member about the longitudinal axis. The rotary motion of the single actuator handle, therefore, is effective to linearly advance a cap assembly and spinal rod into a yoke coupling member secured to the tool and also to rotate at least a portion of the cap assembly to lock the cap relative to the yoke using the same rotary motion of the handle.
