Integra MAYFIELD Instruction Manual page 7

1. After the MAYFIELD Infinity Coupler is mounted to the
Base Unit and O.R. Table, a Headrest can be mounted
to the Socket. Choose the appropriate Headrest and
insert Ball in Socket - be sure to have the T-Knob loose
(full counterclockwise position) before insertion of ball
in socket. An audible "click" will be heard when the
headrest is attached to notify user of engagement.
2. Position headrest and tighten the T-Knob (Figure 2)
fully by turning clockwise.
CAUTION:
Always be sure the T-Knob is locked to prevent
patient head movement.
Adjust Faceplates of Infinity Horseshoe Headrests,
Adult or Pediatric
3. To adjust Faceplates, turn Faceplate Locking Knob
counterclockwise to that Faceplates are moveable.
Then, position Faceplates to accomodate head size.
Fully tighten the Faceplate Locking Knob by turning
clockwise. (Figure 5)
Position Mini Gel Pads of Infinity General Purpose
Headrest
4. Push the Mini Gel Pads as far as possible into the
receptacles on the General Purpose Headrest. The gel
Pads may be rotated into desired position. (MAYFIELD
Skull Pins may also be inserted in receptacles for
patients 5+ years of age.)
Simultaneous Application of Skull Clamp (Figure 6)
5. While the patient's head is positioned on a headrest, a
Skull Clamp may be applied (ages 5+) simultaneously.
CAUTION:
The headrest may be adjusted while a Skull Clamp
secures the patient's head to relieve pressure. If
this is necessary, be certain to manually hold the patient's
head to prevent slippage from the Skull Clamp.
