Always be sure to do the following:
Position the patient in such a way that s/he is not in contact with any
metal parts that are grounded or have a significant electric capacity
against ground (e.g. operating table, fixtures). If necessary, interpose
antistatic drape.
Ensure that the patient will not be in contact with any damp cloths,
drapes or bedding.
Safeguard areas prone to strong perspiration against skin contact with
the trunk of the patient's body by inserting antistatic tissue between
such areas and the trunk.
Siphon off urine with a catheter.
For heart surgery, ground the HF generator via the potential equaliza-
tion connection.
For patients with cardiac pacemaker or other active implants, consult
with the relevant medical specialist prior to applying HF surgery, so
that irreparable damage to the pacemaker or implant can be avoided.
If possible, remove from the vicinity of HF electrodes any electrodes
from physiological monitoring devices that are not equipped with pro-
tective resistors or HF dampers.
Do not use needle electrodes for intraoperative monitoring.
Arrange the wires and cables of monitoring devices in such a way that
they do not come in contact with the patient's skin.
Keep the leads to the HF electrodes as short as possible, and arrange
them in such a way that they do not touch the patient or any other
wires or cables.
Should the output power appear insufficient with the usual settings,
check that:
– the working electrodes are clean,
– all plug connections are properly in place.
Never lay active electrodes on or next to the patient.
Put down active electrodes that are not needed at any particular
moment, in such a way that they will not touch the patient.
For operations involving unavoidable, continuous contact between the
electrodes and the patient (e.g. endoscopic procedures), press the
power OFF/ON switch 12 to switch off the HF generator immediately
after any inadvertent activation of the electrode.
Do not remove hot electrodes from the patient's body immediately
after performing cutting or coagulation procedures.
During operation of the generator, do not touch the electrodes on the
instrument (on the upper or lower side) as the electrodes can heat up
and this may lead to burns or injuries.

Intended use
The Lektrafuse HF generator GN200 is used for vessel sealing and vessel
division in open and minimally invasive surgery. The instruments can seal
vessels of up to and including 7 mm.
The Lektrafuse HF generator is not suitable for use in tube steriliza-
tion/tube coagulation for sterilization.
With respect to the electric shock hazard, the Lektrafuse HF generator
meets the classification and safety requirements of a type CF device.
The Lektrafuse HF generator is intended only for indoor operation and
storage.
2.4
Operating principle
The Lektrafuse HF generator GN200 works on a micro-processor con-
trolled basis and converts the voltage of the mains supply into a high-fre-
quency alternating current for bipolar vessel sealing.
The sealing process is carried out via a closed control circuit. The sealing
can be started and stopped via a button on the instrument or a foot
switch.
The Lektrafuse HF generator GN200 has two operating modes:
Standard mode: Pre-set operating mode
Plus mode: Operating mode with increased energy output
