Zusammenfassung:A stylet control system (7000) for selectively advancing and retracting a stylet includes a stylet (7150) having a first end and a second end, the second end being threaded, a screwdriver (7170) defining a bore for receiving a portion of the stylet and having a screw-engaging end for engaging a screw, the stylet being rotationally fixed relative to the screwdriver. The system includes a control device having a passage for receiving the screwdriver and having an inner portion defining a lumen for receiving the portion of the stylet, the inner portion being threaded for engaging the threaded second end of the stylet, when the screwdriver is rotated in the first rotation direction and the control device is prevented from rotating, the screwdriver advances the screw in the first axial direction and the stylet retracts in a second axial direction, opposite the first axial direction.
