Skull Clamp Patient Fixation
Failure to properly position the patient and to fully secure all adjustment portions of
this or any support device may result in serious patient injury.
1. Unlock the Swivel Lock Knob so the rocker arm can rotate freely 360 degrees. The Swivel Lock
Knob is unlocked by rotating the knob to align the arrow with the open lock symbol; see Figure
7.
2. Rotate the rocker arm into the desired position for placement of the skull pins; normally
perpendicular to the floor for prone or supine positions or parallel to the floor for patients in the
sitting position.
NOTE: The Torque Screw force gauge provides the surgeon with a visual display of the
clamping force value. Each scribed line indicates a 20lbs. (89N) increment of force. See
Table 2 Torque Screw Line Indicator/Clamping Force.
This will also align the rocker arm parallel with the direction of the surgical force (See Table 1
Skull Clamp Position Diagram).
