3.2. Bipolar modes
Optimal results can be achieved using the bipolar method (particularly in
minimally invasive surgery) only with special special instruments!
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 attach a neutral electrode to the
patient, so that the corresponding risks for the patient are
eliminated.
Two bipolar outputs on the ARC 350 facilitate the independent
configuration of two instruments.
Instruments can be connected to the bipolar outputs 3 and/or 4 (socket
43 and/or 47). The desired output is activated by pressing the
key/display 44 and/or 48 (for "Bipolar output 3 and/or 4").
The AUTOSTART function can be activated only for bipolar coagulation.
In the AUTOSTART function, 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 operated in AUTOSTART mode is activated using the foot
switch, the AUTOSTART function is deactivated and the foot switch
signal is used.
To prevent any activation problemsin AUTOSTART mode, we
recommend bipolar cable with a maximum length of 4.5 meters.
3.2.1. "Soft COAG" mode
If you wish to change the settings of the "Soft COAG" mode, see
Chapter Menu program 4 "Bip Coag Mode", Page 59.
The "Soft COAG" mode is used for precision work with the bipolar
tweezers. The AUTOSTART function is not available in this mode.
