The craniostat consists of a lower part and an upper one, connected by two
carbon rods (2).
The lower part consists of a base (1) which is fitted in the chinrest seat with
metal pins and that can be removed by simply pulling upwards.
The chinrest (3) is fitted in the dedicated inserts in the base (1) by means of
pins and can be removed simply by sliding it upwards.
The bite piece (4) is fitted in the suitable hole of seat (1): once it is set at the
desired height, pull the central lever (5) from the left (unlocking position
) to
the right (locking position ) in order to centre it and lock it in place.
In order to remover it, remember to move lever (5) to the locking position and
slide it out from its seat.
The upper part is composed of a cross member (6) that can slide vertically on
the carbon blades (2).
The cross member contains the front support (7) that slides inside its seat in
order to adapt it to the patient’s anatomy.
After having correctly positioned the patient’s head,:
a - push front support (7), making the
pad rest against the patient’s forehead,.
b -
rotate the arms (8) towards the patient’s temples, ensuring that the rubber
blocks at the ends of arches (9) adhere to the head anatomy.
c - rotate levers (10) downwards to ensure a correct locking.
At the end of the exposure, rotate the levers upwards to unlock arms, thus allowing the patient to get out easily
In examinations where the undernose support (11) is used, it should be fitted INSTEAD OF THE CHINREST in the
inserts in the base and pushed FULLY DOWN INTO PLACE.
