Electrosurgical Unit Minicutter
Revision 08

4.6.3
Selection of the Current Type
The unit has two monopolar operating modes and one bipolar one:
•
Monopolar Cut (monopolar cutting)
•
Monopolar Coag (monopolar coagulation)
•
Bipolar Coag
(bipolar coagulation), see section 4.7.3 “Selecting the Bipolar Operating Mode”, page 19)
The front is divided into two control fields for distinction of the monopolar operating modes:
Monopolar Cut
In the control panel
Monopolar Cut
that is marked
yellow
on the
front plate of the unit, an indicator LED (2) indicates the activation of
cutting current, and there are two different current types available
for cutting. These are:
Cutting 1
Clean cut without eschar formation
Cutting 2
Cutting current with eschar formation
Monopolar Coag.
In the operation panel
Monopolar Coag.
that is marked
blue
on the
front plate of the unit, an indicator LED (5) indicates the activation of
monopolar coagulation current, and there are two current type
available for coagulation:
Contact coagulation
Coagulation with high depth upon direct contact between electrode
and tissue
Spray coagulation
Coagulation current with low depth for surface coagulation with
sparks (fulguration).
When working with monopolar coagulation currents, there is a risk of burns from use of insufficiently
isolated instruments!
If instruments and active electrodes are not sufficiently insulated, there is the danger of exposure of the
user to HF voltage. The operating glove is no defined electrical insulation. It does not protect from
possible arcing.
In cases of indirect application using a hand-held instrument (surgical forceps), this instrument should be
insulated in a manner that the user is not exposed to the HF voltage transmitted to the instrument.
