Skull Clamp Patient Fixation
WARNING!
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 laceration, skull fracture, or even death.
WARNING!
WARNING: MAYFIELD Skull Clamp fixation devices are not recommended for use
on children under five (5) years of age and extreme caution should be exercised in
pediatric cases because of the thin skull.
CAUTION!
CAUTION: 60 lbs. (267 N)of force is recommended for adults. 40 lbs. (178 N) of force
is recommended for children. All force settings are at the user’s discretion. NEVER
exceed 80 lbs. (356 N) of force. Do not over tighten.
1. Unlock the locking knob so the rocker arm can rotate freely 360°. The locking knob is unlocked
by rotating it counter-clockwise one (1) complete turn or 360°.
2. Rotate the rocker arm into the desired position. This position is normally perpendicular to the
floor for prone or supine positions. This will also align the rocker arm parallel with the direction
of the surgical force (Table 2 on back).
3. Position the two (2) skull pins in the rocker arm so they are equidistant from the centerline of
the head (Figure 11).
