size and mesh properly. Failure to do so may damage
fittings. (Figure 4 shows typical sunburst connection and
proper meshing of teeth).
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.
Make certain to securely attach the base unit to the
operating room table.

Service Notes

1. A routine check made well before each case will
help avoid problems. The check should include the
following:
Check the plunger locking the ratchet arm in place for
movement as follows:
a. Remove the ratchet arm and hold the body with the
release mechanism pointed toward the floor.
b. Apply pressure upward while looking for movement.
If the release mechanism moves 1.6mm or more, the
unit should be returned for service.
2. While rotating the rocker arm 360 degrees lock and
unlock the index knob. To ensure proper locking
engagement, the knob must always turn a minimum
of 60 degrees. If it does not lock, a slight additional
rotation of the rocker arm should allow the locking
mechanism to engage. If difficulties are encountered,
the unit should be returned for service.
3. With the skull pin removed from the 80 psi torque
screw, apply as much force as possible over the hole
and check for movement of the index shaft. If rubber
protrudes from around the shaft, the unit should be
returned for service.

Cleaning and Sterilization

Plastic components may be damaged by heat.
Manual Wash
CAUTIONS
• Alkaline and highly acidic detergents and solutions
cause damage to the devices.
• Channels and crevices found on this device require
particular attention during cleaning.
• Pay special attention to the water quality used
throughout reprocessing. Hard water can damage
the surface of the equipment. Avoid using hard water.
Instead use purified water unless otherwise specified.
Limitations on reprocessing
• Repeated processing has minimal effects on these
devices. Product life is normally determined by wear
and damage due to use.
• It is important to have Integra NeuroSpecialists
perform routine inspections (twice yearly is
recommended). See contact information below.
INSTRUCTIONS
Containment/Transportation
