Before Use
Intended use
The ESG-400 is an electrosurgical generator intended for tissue cutting and
coagulation in open, laparoscopic and endoscopic surgery in conjunction with
electrosurgical accessories and ancillary equipment.
Contraindications:
Electrosurgical interventions are contraindicated if, in the judgment of the
physician, tissue coagulation and cutting could have a negative effect on the
state of the patient. Electrosurgical tissue coagulation and cutting may be
contraindicated for patients with cardiac pacemakers, a weakened immune
system or blood coagulation disorders.
Application of high frequency treatment
If there is an official standard on the applicability of high frequency treatment as
defined by a national or local medical administration, or other institution, such
as an academic society, follow that standard when performing the procedure.
Before performing any high frequency treatment, study the properties, purposes,
effects and possible risks thoroughly (nature, extent, probability and imminence)
associated with the planned treatment and any alternative therapeutic method
that can be performed. Carry out high frequency treatment only when its
benefits outweigh its risks. Fully explain to the patient the possible benefits and
risks of high frequency treatment as well as those of any therapeutic method(s)
that can be performed instead of electrosurgery, and perform high frequency
treatment only after patient consent is granted. During high frequency treatment,
continue to evaluate the potential benefits and risks, and stop the treatment if
the risks become greater than the possible benefits to the patient.

Burns
WARNING Patient and / or user
The maximum output voltage characteristics of
the electrosurgical generator are shown in the
diagrams in “Output characteristics” in the
Appendix. When setting the power level, first
set it to a low level and increase it gradually. If
the output is initially set to a high level, the
electrode’s insulation may be damaged and
cause user and / or patient burns. However,
certain modes may present an unacceptable
risk at low output power settings. For example,
with the PulseCut fast mode or PulseCut slow
mode, the risk of an excessive thermal effect
rises if the output power setting is too low.
Therefore, it is recommended that you perform
basic testing before using the electrosurgical

Important Information – Please Read Before Use 11
W7.091.601 ELECTROSURGICAL GENERATOR ESG-400
generator. If the instruction manual of the HF
instrument to be used stipulate a rated voltage,
the output should be set so that it does not
exceed that voltage.
Contact with the tip of the electrodes may
cause burns when the electrosurgical generator
is active.
During operation, temporarily unused
electrodes should be stored in an electrically
insulated container. Unused electrodes or HF
instruments should never be placed on the
patient. Otherwise, it may cause patient and / or
user burns.
To prevent patient burns, the electrosurgical
generator and ancillary cords should not come
in contact with the patient or metal parts of the
operating table. Furthermore, the patient should
also be kept away from metallic parts of the
operating table or other devices. Remove any
metallic items from the patient (wristwatches,
jewelry, etc.) before starting the procedure.
If the electrosurgical generator is used in
conjunction with another electrosurgical
generator, never use both generators
simultaneously. Keep the HF instrument
connected to the not-used electrosurgical
generator away from the target area while the
other generator is in operation. Do not activate
output of both generators simultaneously.
Patient or user injury may occur due to the
concentration of electric current.
To prevent patient burns, the patient’s skin
surfaces should not touch each other (e.g. bare
arm and side of chest) or any metal items in the
procedure room.
To prevent patient burns during high frequency
treatment, the patient’s clothes must be dry.
During endoscopic treatment be sure that the
distal end of the endoscope and / or HF
instruments do / does not contact bridging fluids
surrounding the target tissue. Electric current
may flow to the surrounding tissue via the fluids
and cause burns. This does not apply to
instruments intended for use in conjunction with
conductive fluids.
The endoscopic treatment performed should
not include an operation in which part of the
treated tissue (polyp head, etc.) or part of the

12 Important Information – Please Read Before Use
ELECTROSURGICAL GENERATOR ESG-400 W7.091.601
endoscope distal end or endotherapy
instrument is in contact with or close to
surrounding tissue during high frequency
exposure. Otherwise, current flows to the tissue
through the part of the treated tissue, the
metallic parts at the endoscope’s distal end or
endotherapy instrument and may cause burns.
When using an electrocardiograph or other
physiological monitoring equipment
simultaneously with the electrosurgical
generator on a patient, any monitoring
electrodes should be placed as far away as
possible from the electrodes used with the
electrosurgical generator. If placed too close,
high frequency signals or spark discharge noise
from the electrosurgical generator may interfere
with the operation of an electrocardiograph or
other physiological monitoring equipment.
Needle monitoring electrodes should not be
used, as they may cause patient burns.
Physiological monitoring equipment
incorporating high frequency current limiting
measures is recommended.
To prevent burns, the user and assistant should
wear surgical gloves during the procedure.
CAUTION High frequency leakage current
Wherever possible, the patient should not be able
to come into contact with electrically conductive
components that are grounded. Route all
connecting cables so that they are not in direct
contact with the patient or other cables. Capacitive
coupling may occur.
Potential hazards for the heart
DANGER Shock hazards to the heart
To prevent shock hazards, never apply the
electrosurgical generator to the heart in
combination with type B or BF applied parts.
When using the electrosurgical generator on or
in the vicinity of the heart, be sure to use it with
the minimum necessary output. Spark
discharge during operation may affect the heart.

W7.091.601 ELECTROSURGICAL GENERATOR ESG-400
DANGER Pacemaker / Defibrillator malfunction
The high frequency equipment, when applied to a
patient with a cardiac pacemaker, an implanted
cardioverter defibrillator (ICD) or other implanted
electronic devices (IED), may cause
malfunctioning or failure of the implanted electronic
device and may seriously affect the patient. Always
confirm that it is safe to proceed with a cardiologist
or the manufacturer of the implanted electronic
device before proceeding. If monopolar modes of
the electrosurgical generator are used, position the
neutral electrode so that the current pathway does
not pass through or near the implanted electronic
device and its lead system. The risk of malfunction
or failure of an implanted electronic device is
reduced by the use of a bipolar mode. A risk does
exist, however, if the application is in close
proximity to the implanted electronic device.
WARNING Cardiac emergency
Always keep a defibrillator ready in case of a
cardiac emergency. During operation of the
defibrillator, remove the endoscope and / or
laparoscope and HF instruments from the patient.
Fire / Explosion
DANGER Ignitable anaesthetics and gases
The risk of flammable gases or other materials
being ignited exists with any surgical application of
electrical energy. Precautionary measures must be
taken to keep flammable materials and substances
away from the site of intervention (do not use
flammable anaesthetics, nitrous oxide or oxygen).
Otherwise, explosion or fire may result and cause
serious injuries. This electrosurgical generator is
not explosion-proof. Do not use the electrosurgical
generator within an explosion zone.
WARNING Ignitable gas in the gastro-intestinal tract
If the intestines contain a flammable gas, replace
this gas with air or a non-flammable gas before
performing the operation, to minimize the risk of
fire or explosion.

14 Important Information – Please Read Before Use
ELECTROSURGICAL GENERATOR ESG-400 W7.091.601
WARNING Ignitable cleaning- and disinfection agents
Flammable agents used for cleaning and
disinfection must be allowed to evaporate
before the electrosurgical generator is used.
Also ensure that flammable solutions are
neither on the patient’s skin (e.g. under neutral
electrode) nor in the patient’s body cavity when
the electrosurgical generator is used.
Non-flammable agents should be used for
cleaning and disinfection wherever possible.
WARNING Ignitable materials
If absorbent cotton or gauze is used during the
procedure, it can be ignited by a spark
generated in the normal operation of the
equipment.
When performing electrosurgery, sparks occur
which could lead to burning or deflagration of
combustible materials.
Body hair is flammable. Water soluble surgical
lubricating jelly may be used to cover hair close
to the surgical site to decrease flammability.
WARNING Risk of fire
Disconnect the power plug before changing the
fuses! Replace fuses as marked. The fuses must
only be replaced by authorized technicians!
Procedural hazards and complications
DANGER Procedural hazards and complications
The safety of electrosurgery will be greatly
enhanced by a thorough knowledge of the
medical literature on the subject. Study of
specific information on the hazards and
complications of the procedure in question is
especially recommended.
To respond to possible patient bleeding,
prepare at least one of the following three
haemostatic procedures: coagulation, clipping
or local injection.
To prepare for possible accidents, emergency
equipment for life-saving, intubation and
appropriate pharmaceuticals should be located
in or near the procedure room.
Always prepare a spare electrosurgical
generator or an alternative procedure to avoid

Important Information – Please Read Before Use 15
W7.091.601 ELECTROSURGICAL GENERATOR ESG-400
interruption of treatment due to an unexpected
electrosurgical generator failure during
treatment.
Should any abnormal output be suspected
during operation, immediately terminate the use
of the equipment by releasing the footswitch. If
the footswitch does not react, switch off the
electrosurgical generator. Otherwise,
malfunction of the equipment may cause an
unintended increase in output.
Use physiological monitoring equipment
throughout the entire procedure, for continuous
observation of the patient’s condition.
For procedures where the high frequency
electrical current could flow through parts of the
body with a relatively small cross sectional area,
the use of a bipolar mode may be desirable in
order to avoid unwanted tissue damage.
It is not recommended to use electrosurgery for
circumcisions because of the risk of thermal
injuries. The risk can be reduced if metal parts
of any kind (e.g. clamps) and / or monopolar HF
instruments are avoided.
WARNING Safety measures during the procedure
Wear personal protective equipment to guard
against dangerous chemicals and potentially
infectious material. During operation, wear
appropriate personal protective equipment,
such as eye wear, face mask, moisture-
resistant clothing and surgical gloves that fit
properly and are long enough so that your skin
is not exposed.
Studies have shown that smoke generated
during electrosurgical procedures can be
irritating and potentially harmful to surgical
personnel. These studies recommend the use
of surgical masks and adequate ventilation of
smoke by the use of surgical smoke evacuators
or other means.

16 Important Information – Please Read Before Use
ELECTROSURGICAL GENERATOR ESG-400 W7.091.601
WARNING Output performance
If the electrosurgical generator fails and the
output is stopped during treatment, it may be
impossible to continue treatment due to tissue
or coagulum build-up on the HF instrument or
other similar condition.
During endoscopic treatment never grasp the
target tissue with non-insulated grasping
forceps. Non-insulated grasping forceps will
disperse the electric current and normal
operation may be impeded.
WARNING Electrical stimulation of nerves and muscles
Nerves and muscles can be stimulated by low
frequency electrical currents or intense high
frequency electrical currents. Low frequency
electrical currents may be generated by a partial
rectification of intense high frequency electrical
current, in particular when there is a spark
discharge to the tissue or to another metallic object.
Intense high frequency electrical currents can
occur at the beginning of an electrosurgical cut or
when using high output power settings. This may
cause violent spasms or muscle contractions. Use
the lowest appropriate power level and effect (e.g.
effect 1 instead of effect 3). However, for certain
modes a low output power setting may present an
unacceptable risk for the patient. For example, with
the PulseCut fast mode or PulseCut slow mode,
the risk of an excessive thermal effect rises if the
output power setting is too low.
CAUTION Generator defect
To prevent electrosurgical generator damage,
never short-circuit electrodes (accessories,
neutral electrodes).
In the event of a defect or malfunction in the
electrosurgical generator, an undesirably high
output power may be emitted.
