Adjusting the settings of the HF device and use of the
accessories
Setting the output power too high can injure the patient. Therefore,
before you increase the output power, ensure that:
the neutral electrode is correctly positioned,
the working electrodes are clean,
and the plug connections are all correct.
Setting the
HF device correctly
To prevent inadvertent (thermal) tissue damage during operations
on body parts with small cross sections and in areas with high
resistance (bones or joints), use the bipolar method in these areas.
Set the acoustic signal that sounds when the electrode is activated
so that it is always clearly audible.
Nerve and muscle stimulation by low-frequency currents.
In HF surgical applications (especially applications in which an arc is
formed) part of the HF current is converted into a low-frequency current.
This current can trigger muscle contractions in patients.
To minimise the risk of patient injury, set the power and effect as
low as possible.
Correct usage of the accessories
Use only insulated accessories.
Check all electrodes for sharp edges and projecting parts before
use.
Use only electrodes that are free of defects and in good working
order.
Never place active electrodes on or near the patient.
Do not remove hot electrodes from the patient's body directly after
cutting or coagulation.
Ensure that there is sufficient distance between the patient cables
and the cables of the HF device.
Do not run the patient cable across the patient.
