Purge function
Figure 5-5:
Purging active
When the Purge button
3
is pressed, the instrument is purged with argon for a few
seconds. This process is required in particular for argon-assisted electrosurgery in
the gastrointestinal tract. The flammable or explosive endogenous gases that must
be assumed to be present there must always be purged with CO
2
or argon in the
endangered intestinal section before activating the HF device and argon
coagulation.
Pressing the Purge button
3
can also help to remove any tissue deposits in the
lumen near the electrode tip. For this reason, purging should also be carried out if
the plasma does not ignite.
The gas status indicator
4
lights up green during purging.

Post-surgery instructions
The procedure described below is recommend after completion of surgery.
5.6.1. Shutting off the argon gas
Check the primary gas pressure on the pressure gauge of the pressure reducer. If
it is less than 30 bar, exchange the gas bottle. Activation is not possible with a gas
pressure below 2 bar. If there is still sufficient pressure in the gas bottle, close the
bottle valve by hand to prevent potential gas loss.
5.6.2. Exchanging the gas bottle
Close the bottle valve by hand and disconnect the pressurised gas line from gas
connector
12
or
14
on the rear panel of the ARC PLUS, and disconnect the
electronic pressure sensor (if present) from connector
11
or
13
.
Then press the pressurised gas line connector onto bleed stub
9
on the rear panel
to allow the residual pressurised argon to escape. After this the pressure reducer
can be manually unscrewed from the gas bottle and a new bottle can be fitted.
Observe the use instructions for the pressure reducer. Ensure that the gas bottle is
securely attached to the equipment trolley. Switch off the HF device.
