Installation - Carlo De Giorgi SURGERY PLUS Mode D'emploi

●
For SURGERY PLUS the rod neutral electrode must be held solid in patient's
hand.
●
When high frequency electrosurgical unit and physiological monitoring devices
are used at a time in the same patient, all the monitoring electrodes, that have
not resistive or inductive elements tested in high frequency interference environ-
ment, must be as far as possible from the electrodes of the electrosurgical unit.
Avoid the use of monitoring needles.
●
The connection to the electrodes should be located in such a way to avoid the
contact both with the patient and with other cables.
●
The power level should be the lowest useful to the work to do.
●
Always check the return plate whenever electrosurgical unit fails to produce the
desired effect. Reason for a low output power level, or for an incorrect function-
ing of the electrosurgical unit when arranged for a normal output, may be lack of
connection of the return plate or its imperfect placement.
●
The use of flammable anesthetics, of oxygen and of nitrogen protoxide should
be avoided in the case of operation at the head or at chest level except the pos-
sibility of evacuating gas. Flammable materials used to clean, or to disinfect,
should be let to evaporate before the use of the electrosurgical unit. There is
risk of stagnation of flammable solutions under the patient or in body cavities as
the umbilicus and the vagina. The fluid that deposits in these areas should be
removed before the equipment use. The danger of endogenous gas ignition has
to be considered. Some materials like cotton wool or gauze, when saturated with
oxygen, may burst into flames because of the sparks produced by the equipment
in the normal use.
●
There is a risk for the patients fitted with heart pacemaker or other stimulation
electrode: interference may occur with the stimulator signal or the stimulator
itself can be damaged. Please refer to Cardiology Unit when in doubt.
●
Electrosurgical equipment does emit unnoticed radiation of high frequency en-
ergy that may effect other medical equipment, unrelated electronics, telecom-
munications, and navigational systems.
●
The accessory must be regularly checked, particularly the cables for the elec-
trodes and the possible accessories for the endoscopy to verify that the insula-
tion is not damaged.
●
To avoid the connection of incompatible accessories to the unit, the insulation
characteristics of the items to be replaced must be requested to the manufac-
turer and compared to those of the supplied unit (see Technical Characteristics).
●
Attention: a damage of the electrosurgical unit could result in an unwanted in-
crease of the output power.
●
Inadvertent stimulation of a patient's muscle and nerves can be caused by low
frequency currents originating in electric sparks between electrode and tissue
of the patient. Should neuromuscular stimulation occur stop surgery and check
all connections to generator. If this does not solve the problem, qualified service
personnel must inspect generator.

Installation

●
The electric safety is insured only when the same are correctly connected to an
efficient net linked to the earth in conformity with the actual safety requirements.
It is necessary to verify this fundamental safety requisite and, in case of doubt,
to require an accurate control of the plant from part of qualified personnel. The
manufacturer cannot be considered responsible for possible damages caused
from the lack of efficient connection to earth of the installation. Operation without
a protective earth connection is forbidden.
●
Before connect the equipment ascertain that the required voltage (showed on
