7.0 Hints for avoiding of
mistakes
• Be sure that the power paths between
neutral electrode and MICTEC HF
instruments are as short as possible.
• The power path must not cross through
the body and absolutely never across the
thorax.
• The HF cable and the HF instrument must
not be allowed to lay directly on the patient’s
skin, as this could lead to burns caused by
capacitive currents.
• The HF cable must not be allowed to
coil or lay in a coil as this could result in
dangerous inductive currents.
• Completely insulate the patient from any
contact with any other conductive surfaces.
• Ground the operation table!
• Avoid skin-to-skin contacts on arms and
legs of the patient, for example by wrapping
in dry gauze.
• Switch on HF power only when the HF
instrument is in contact with the tissue that is
to be coagulated.
• The tissue to be coagulated must not
be in touch with any part of other tissue
surfaces, since it could lead to unwanted
coagulations.
• Cord or band shaped tissue parts may be
coagulated only at the thinnest part.
• The coagulating HF instrument tip must
be at least 10 mm from other surgical
instruments.
• When using gas, for example insufflation
gas, make sure that only non-inflammable
gas is used, otherwise explosions and
oxygen burns could result.
• The size of the neutral electrode must be
appropriate for the power of the HF used, as
it could lead to burns on the wrong place.
