Settings and recommended parameter values
The recommended settings for HF power and argon gas flow stated in the previous
section are based on experience. Specific working methods or other probes may
make adjustments to these settings necessary, at the discretion of the surgeon. A
general rule is that coagulation, especially endoscopic, must always be performed
in plain view in order to avoid direct tissue contact.
Observe the instructions for use of the accessories concerned when selecting
setting values. Selecting unsuitable parameter values may lead to damage to the
accessories and/or injury to the patient.
Recommended settings for various argon applicators
Using the ARC HF generator in argon modes
With argon plasma coagulation, the combination of the spray voltage from the HF
generator in the instrument or probe and the argon flow from the ARC PLUS forms
a plasma jet. This plasma jet has a broad contact area on the tissue. The
coagulation effect is self-limiting both in depth and on the surface. Argon plasma
coagulation is primarily used in endoscopy (rigid or flexible). Argon plasma
coagulation is also used in open surgery.
Cutting
Figure 5-1:
Cutting active
“Monopolar Cut – Argon” mode
This setting is intended to be used for argon-assisted cutting in open surgery with
rigid argon probes. The coagulation effect is secondary here. This operating mode
results in less smoke formation than cutting without argon assistance. The gas
status
4
lights up yellow when Cut mode is active.
Coagulating
Figure 5-2:
Coagulation active
“Monopolar Coag – Argon Open” mode
This setting is intended to be used for argon-assisted electrocoagulation in open
surgery with rigid argon probes. When a coagulation mode is active, the gas status
indicator
4
lights up blue.
