Inadvertent tissue damage
WARNING
Safety margin between the active instrument and sensitive tissue
structures too narrow
Adjacent structures can be damaged by the thermal effect of electro-
surgery.
Ensure that there is a sufficient safety margin between the active
instrument and sensitive tissue structures (e.g. nerves, muscles).
CAUTION
Electrically conductive implants can redirect or concentrate cur-
rent flow.
Risk of burns for the patient and possible damage to the implant.
In the case of patients wearing electrically conductive implants,
consult the manufacturer of the implant or the relevant specialist
department of your hospital prior to surgery.
Position the neutral electrode so that the implant is not located
between the active electrode (monopolar instrument) and the
neutral electrode.
Stimulation of nerves and muscles
WARNING
Low-frequency currents stimulate nerves and muscles (Neuro-
muscular Stimulation)
Low-frequency currents arise either due to low-frequency power
sources or partial rectification of the HF current. Spasms or muscle
contractions can occur.
Risk of injury to the patient.
Set power as low as possible relative to the required surgical ef-
fect. If the required surgical effect is not achieved, increase the
power.
Risks due to incorrect use of the neutral electrode
WARNING
Non-compatible or single surface neutral electrode
When applying a non-compatible neutral electrode, it should be ex-
pected that monitoring the contact between neutral electrode and
skin is faulty.
When applying a single surface neutral electrode, the contact be-
tween neutral electrode and skin is not monitored. If contact between
neutral electrode and skin is inadequate, the unit does not emit any
visual and acoustic signal.
