3.2. Bipolar modes
Special instruments are necessary in order to achieve optimal results
using the bipolar method (particularly with minimally invasive surgery).
Advantages of the bipolar method:

The required high-frequency output is only one-fourth of the
output required for the monopolar method.

It is not necessary to apply a neutral electrode to the patient,
which eliminates the associated risks to the patient.
Instruments can be connected to the bipolar output (socket
connector
31 ).
The AUTOSTART mode can be activated only for bipolar coagulation.
In the AUTOSTART mode, the coagulation current is automatically
added after low-resistance tissue contact of the connected bipolar
instruments. Thus activation using the foot switch is not necessary.
If an output operating in AUTOSTART mode is activated using the foot
switch, AUTOSTART mode is deactivated and the foot switch signal is
used.
This type of current can be used for bipolar cutting instruments.
This type of current is suitable for the application of bipolar scissors, e.g.
BOWA BiZZER.
To prevent activation problems in AUTOSTART mode, we recommend
limiting the bipolar cable length to 4.5 meters or less.
Forceps
Under moist conditions the forceps may be released accidentally, for
example by contact with blood. This can cause an undesirable increase
in the duration of the surgical therapy.
When the forceps are set aside with AUTOSTART enabled, inadvertent
activation with associated risk of injury may occur when the forceps are
wiped with a moist cloth or come in contact with metallic components,
such as other instruments.
