Perforators
Perforator (05.001.054)
Gear reduction: 97:1
The perforator is used with the related trepan burrs
(03.000.350–03.000.351) including the protective
sleeves (05.001.096–03.001.097) to open a cranium
with a thickness of 3 mm or above. The handpiece has to
be in the FWD position. Hold the perforator perpen-
dicular to the skull at point of penetration and always
apply constant pressure when the trepan burr is en-
gaged in the bone. As soon as the cranium is cut
through, the trepan burr automatically disengages.
Changing trepan burrs
1. Turn the release sleeve for trepan burrs (1) until
the locking pin (2) disengages from the locking
groove (3). (Position , Fig. 1).
2. Pull off the trepan burr together with the protective
sleeve.
3. Insert a new trepan burr into the protective sleeve and
make sure that the pins on the trepan burr engage
properly in the grooves in the protective sleeve.
4. Place the new trepan burr together with the protec-
tive sleeve on the perforator.
5. Turn the release sleeve for trepan burrs (1) until the
locking pin (2) engages in the locking groove (3).
(Position , Fig. 2).
Precautions:
•
If conditions such as adherent dura, intracranial
pressure or other underlying abnormalities are
present in the area of the penetration, the perfora-
tor may cut the dura. Caution must be observed
when perforating thin skull areas such as tempo-
ral bone, infants, children, elderly, or diseased
bone since skull consistencies and thicknesses can
vary and the dura could be cut. Only use the per-
forator 05.001.054, the trepan burrs 03.000.350–
03.000.351 and the protective sleeves 05.001.096–
05.001.097 on bones with a thickness of 3 mm or
above.
•
It is recommended to cool the trepan burr during
trepanation (use the irrigation nozzle 05.001.076).
•
Check function before each use of the perforator.
