CAUTION: 60 lbs. (267 N) of force is recommended for adults. 40 lbs (178 N) of force is recommended for

Skull Clamp Patient Fixation
Failure to properly position patient and to fully tighten and secure all adjustable portions of this or any
similar device may result in skull pin slippage and serious patient injury, such as scalp lacerations, skull
fracture, or even death.
1. Unlock the Index Locking Knob so the rocker arm can rotate freely 360 degrees. The Index
Locking Knob is unlocked by rotating the knob to align the indicator with the open lock
symbol; see Figure 4.
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 line on the gauge is 20 lbs or 89 N).
This will also align the rocker arm parallel with the direction of the surgical force
(See Table 1 Skull Clamp Position Diagram).
CAUTION!
WARNING!
