►
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 for operation and storage in
closed spaces.
2.4
Operating principle
The Lektrafuse HF generator GN200 works on a micro-processor controlled
basis and converts the voltage of the mains supply into a high-frequency
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
