Unintentional activation of the instrument during an endoscopic
application
If the instrument is activated and remains activated during an endo-
scopic application, the patient can suffer burns when the instrument
is removed.
All points that come into contact with the active part of the instru-
ment are at risk. The cause of unintentional activation can be a fault
in the footswitch or device for example.
You will recognize unintentional activation from the continuous acti-
vation signal, even though you have released the footswitch.
Risk of burns to the patient!
Turn off the power switch on the electrosurgical unit immediately.
Only then should the instrument be removed from the patient’s
body.
Capacitive coupling between the cords of two instruments
When one instrument is activated, current can be transferred to the
cord of another instrument (capacitive coupling).
The patient can suffer burns if the non-active, but still live instrument
has direct or indirect contact with the patient.
Risk of burns to the patient!
Lay the cords of instruments so that they are as far apart as pos-
sible.
Put instruments down in a safe place: sterile, dry, non-conductive,
and easy to see.
Instruments that have been put down must not come into contact
with the patient, medical personnel, or combustible materials.
Instruments that have been put down must not come into contact
with the patient, not even indirectly. An instrument can come into
contact with the patient indirectly through electrically conductive
objects or wet drapes, for example.
In electrosurgical contact procedures: Touch the tissue before ac-
tivating the instrument.
In electrosurgical non-contact procedures (APC, spray coagula-
tion): Place the instrument at the usual working distance from the
tissue before activating the instrument.
Capacitive coupling between the instrument and the hybrid trocar
When an instrument is activated, current can be transferred to the
trocar without any contact (capacitive coupling).
Risk of burns to the patient and medical personnel!
Do not use hybrid trocars (i.e., a combination of metal and plastic)
if you are using monopolar instruments.
