Electrosurgical Unit Minicutter
16 Revision 08
from high HF current concentration!
The hazard potential of electrosurgery increases with the power applied. Therefore please note the
following:
The high-frequency power should be set to the lowest possible setting for the respective application.
An insufficient effect while using the standard setting can, for example, be caused by poorly applied
neutral electrodes, insufficient contact in plug connections, cables that are damaged under the
insulation or encrusted electrodes. This must be checked before the HF power setting is increased.
A defect in the electrosurgical unit may lead to an unintended increase of the output power.
Therefore, a protective circuit to avoid overpowering is integrated into the unit.
4.6.4 Power Setting
For setting the monopolar output power, the power adjuster (1) must be
activated. The power setting is adjusted starting from a predefined minimum
value up to a maximum value depending on the selected current type (see
section 9, “Technical Data”, page 38). The output power increases linearly
with the angle of rotation; the relation for each current type is indicated in the
diagrams. The specified power is always the maximum power that can be
emitted to a nominal load. In surgical applications, the power actually emitted
to tissue is usually lower.
4.6.5 Operation
Upon activation the HF current is switched on according to the previously selected operating mode by
triggering the handle or foot switch. The HF current is provided in accordance with the preset current types
and the set power. After activation, a continuous tone is emitted and the activation LED for the operating
mode lights up.
The rules for application of HF surgery defined in section
5 “Safety Measures”, page 22, must be
observed as a matter of principle; particular attention is to be paid to safe application of the neutral
electrode and optimum positioning of the patient.
• Upon simultaneous activation of two control elements (e.g. the blue and yellow buttons on the
handle), the electrosurgical unit will be blocked and HF power output deactivated.
• After prolonged application of HF current at high power, the surface of the device can heat up
significantly.
• The accessory equipment must be suitable for at least the voltages indicated in section 9 Currents,
their Properties and Technical Data, page 34.
• Only accessory equipment in perfect condition may be used.
