Important Information – Please Read 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.

plugs and sockets, refer to chapter 3.8, “Connection of HF instruments”.

Before use, the electrosurgical generator and accessories must be examined for damage. All cables and its plugs must be free of scratches and cracks. Cables and accessories with damaged insulation or connections must not be used.

Electric shock WARNING

Grounding failure To prevent the risk of electric shock, the housing of the electrosurgical generator must be grounded. Always connect the power cord plug to a properly grounded wall outlet. Do not use a 3-pin / 2-pin adapter, as it can impair safe operation of the electrosurgical generator.

WARNING

User shock To prevent user shock, malfunction and damage of the electrosurgical generator, keep liquids away from all electrical equipment. If liquid gets on or into the electrosurgical generator, terminate operation immediately and contact Olympus.

CAUTION

Injury during servicing When the housing is opened, there is a danger of electric shock. The electrosurgical generator must only be serviced by authorized technicians.

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

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.

W7.091.601

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

ELECTROSURGICAL GENERATOR ESG-400

12

Important Information – Please Read Before Use

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.

CAUTION

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.

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.

Important Information – Please Read Before Use

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.

WARNING

WARNING

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.

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.

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

ELECTROSURGICAL GENERATOR ESG-400

W7.091.601

15

Important Information – Please Read Before Use

interruption of treatment due to an unexpected electrosurgical generator failure during treatment.

WARNING

W7.091.601

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.

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, moistureresistant 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.

WARNING

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.

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.
