Instructions for Mounting Skull Pins
WARNING:
Before using this product, carefully read the product insert
for correct use and warnings associated with the specific skull clamp
model intended to be used.
CAUTION:
Inspect reusable skull pin points carefully prior to each use.
To achieve proper fixation, pins should be of equal length. Broken,
dull or bent pins should be replaced. It is recommended that a spare
set of pins always be kept available.
1. Hold the skull pins between the thumb and the forefinger at the
base of the pin.
2. Insert the pins into the skull pin receptacles on the skull clamp.
Push them in until they are seated firmly and cannot be inserted
any further into the receptacle.
CAUTION:
The skull pins must be fully seated so there is no gap between
the shoulder of the skull pin and the skull clamp (Figure 3).
CAUTION:
Make sure the trajectory of the single Pin in the Skull Clamp
intersects the center of the patient's head and the Rocker Arm to
correctly secure the patient's head into the Skull Clamp (Figure 4).
Good centerline placement
WARNING:
Do not position the skull pins over the frontal sinuses of the
temporal area of the skull. Take care to avoid major blood vessels,
nerves, previously restored or abnormally thin bone.
CAUTION:
Skull Pins should enter the scalp at a 90° angle.
CAUTION:
60 lb. (267 N) of force is recommended for adults. 40 lb. (178
N) of force is recommended for children. All force settings are at the
user's discretion. Never exceed 80 lb. (356 N) of force.
