MonopolarCut
Monopolar cut is the sectioning of the biological tissue achieved by the
high‐densitypassage of HF current, which is concentrated at point of the
activeelectrode.TheHF current,when it isapplied tothe tissue, through
thepoint of the active electrode, it creates intense molecular heat in the
cells so high th
at explosion of it is caused. The cut effect is achieved by

haemostasiswhile cutting.Becauseitseffectscanbeprecisely controlled,
it can be used safely without damage to the bone, but since good

The following rules help the operator to obtain good cutting, however
every user must follow first of all his professional judgment as he does
