Mectron PIEZOSURGERY WHITE Mode D'emploi Et D'entretien page 32

CAUTION: To correctly use the device,
you must press the foot pedal and start it
with the insert not making contact with the
part to be treated, so that the electronic
circuit can recognize the best point of
resonance of the insert without interferences,
allowing its optimal performance.
WARNING: Before every treatment,
make sure that the insert appropriate for
the treatment is inserted on the handpiece.
Exclusively use the Mectron torque wrench to
fasten the insert to the handpiece. Do not use
any other tools, such as pliers, pincers, etc.
WARNING: The patient must not come
into contact with the device body or the foot
pedal.
WARNING: Do not change the insert
while the handpiece is operating, to prevent
causing wounds to the operator.
WARNING: Be very careful to the sharp
edges of cutting inserts. When tightening and
removing these insert types, the edges may
cause injuries.

WARNING: Breakage and wear-out of
the inserts. High frequency oscillations and
wear-out may, in rare circumstances, lead
to the breakage of the insert. Do not bend,
change shape of, or re-sharpen an insert
in any way. Bending an insert or applying
leverage on it can lead to its breakage.
Deformed or otherwise damaged inserts are
susceptible to breakage during their use.
These inserts must never be used.
Excessive pressure on the inserts during their
use can lead to their breakage. If an insert
breaks, check that none of its fragments
remain in the treated part and, at the same
time, apply effective suction to remove them.
The patient must be instructed to breathe
through his nose during the treatment,
or a dental dam must be used to prevent
the patient from ingesting fragments of
broken inserts. When the nitride coating
wears out, the cutting efficiency decreases;
re-sharpening the insert damages it and is
therefore forbidden. Check that the insert
is not worn out. Use of a worn-out insert
reduces the cutting performance and can
cause necrosis of the bone surface treated.
During the intervention, frequently check
that the insert is intact, especially its top.
During the intervention, avoid prolonged
contact with retractors or with metallic
instrumentation in use.
WARNING: During surgery, do not
perform any maintenance activity on the
system.
CAUTION: Contraindications. Allow
reusable, autoclavable items (the handpiece,
the inserts, the torque wrench, and any other
accessory that can be sterilized ) to gradually
return to room temperature after steam
sterilization and prior to usage. The cooling
process must not be accelerated.
WARNING: Check the level of
physiological solution contained in the
irrigation bag. Replace the irrigation bag with
a new one before it is completely empty.
