Safety information
NOTICE Unsuitable temperature and humidity The electrosurgical generator should only be used under the conditions as described in section “15.2 Ambient conditions for operation, storage and transport” on page 115. Use under other conditions may impede normal performance and/or result in equipment damage. 2.3.3 Risks regarding accessories WARNING Mechanical stress Do not apply excessive bending, straining, or squeezing force to any cords. It may cause malfunction. WARNING Non-compatible and damaged accessories ‒ The electrosurgical generator shall only be used with compatible accessories. ‒ When connecting accessories (cords, electrodes, HF instruments) avoid output settings where the maximum output voltage of the electrosurgical generator may exceed the rated accessory voltage (refer to section “7.3 Power settings” on page 68, and the instruction manual of the accessory). ‒ For a list of compatible neutral electrodes refer to section “14.2 Compatible neutral electrodes” on page 113. For compatible plugs and sockets refer to section “8.2 Description of the output sockets” on page 79. ‒ 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. 2.3.4 Risks regarding electric shock WARNING Grounding failure There is a risk of electric shock if the housing of the electrosurgical generator is not grounded. ‒ Only connect the power cable to a properly grounded fixed socket outlet. ‒ Do not use an adapter for an incompatible grounded fixed socket outlet 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.

Safety information
2.3.5 Risks regarding burns WARNING Burns to the patient and/or the user ‒ The maximum output voltage characteristics of the electrosurgical generator are shown in the diagrams in section “17.5 Output characteristic diagrams” on page 124. 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. ‒ 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 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.

Safety information
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. 2.3.6 Potential hazards to 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. 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. 2.3.7 Risks regarding implants 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. Other electrically conductive implants All electrically conductive implants present a hazard due to concentration or re-direction of HF currents. Qualified advice should be obtained before the electrosurgical procedure. 2.3.8 Risks regarding fire and explosion WARNING Ignitable gases in the bladder Electrolysis that occurs during TCR/is (Transcervical endometrial Resection) and TURis (Transurethral Resection) can produce flammable gases. These gases can ascend into the upper part of the uterus or bladder and can come in contact with the electrode.
12
Safety information
Activating the HF current while flammable gases are present can cause the gases to ignite or explode. This can result in uterine or bladder perforation or puncture, exogenous burns or other injury. ‒ Before activating the HF current, use the endoscopic image to make sure that the distal end of the resectoscope is not located in the flammable gases. The gases are visible as bubbles in the irrigation fluid. ‒ Do not activate the HF current while the distal end of the resectoscope is located in the gases or in their direct vicinity. ‒ Before activating the HF current, evacuate or move the gases or allow the gases to escape from the uterus or bladder as necessary, e.g. by evacuating the gases through the sheath of the resectoscope. WARNING 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. ‒ Do not use the electrosurgical generator within an explosion zone. This electrosurgical generator is not explosion-proof. 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 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.

Safety information
2.3.9 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 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 foot switch. If the foot switch 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. 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.
14
Safety information
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.

1) Electrosurgical generator ESG‑400 2) Double-pedal foot switch WB50402W 3) Instructions for use and Contact information for customers
3.2 Product functions The electrosurgical generator ESG‑400 is designed to be used for the following electrosurgical applications: ‒ Bipolar electrosurgical cutting and coagulation. ‒ Monopolar electrosurgical cutting and coagulation, which requires a neutral electrode. The ESG‑400 is equipped with several cutting and coagulation modes. All settings of the device are done via the touchscreen on the front panel. The ESG‑400 is activated by a compatible foot switch or by a hand switch at the connected HF instrument. The bipolar coagulation mode BiSoftCoag also provides activation via Autostart.
16
Product description
The ESG‑400 is connected to the local power supply. The ESG‑400 can be mounted on the compatible TC‑E400 Energy Cart. Details on the hardware and software, on the correct handling and use of the device are described in the following chapters.
3.3 Features The electrosurgical generator is equipped with the following features: ‒ Contact Quality Monitor (CQM) ‒ High Power Cut Support (HPCS) ‒ Fast Spark Monitor (FSM) ‒ Resistance Controlled Automatic Power (RCAP) ‒ Automatic end of procedure detection 3.3.1 CQM – Contact Quality Monitoring for the neutral electrode When using split type neutral electrodes for monopolar electrosurgery, the ESG‑400 is able to detect unintended detachment of the neutral electrode from the patient. The indicator for the contact quality monitor (CQM) shines green while the contact between the split type neutral electrode and the skin of the patient is within an acceptable resistance range. If the contact between the split type neutral electrode and the patient’s skin is insufficient, then an alarm tone sounds, a warning message is displayed and the CQM indicator shines red. Using non-split type neutral electrodes is not as safe as using split type ones, because CQM is not able to detect any detachment of non-split type neutral electrodes from the patient. For detailed information on the safe and correct use of neutral electrodes refer to chapter “6 Using the ESG‑400 with a neutral electrode” on page 57. 3.3.2 HPCS – High Power Cut Support This feature optimizes the start of the cutting procedure by applying high power to the tissue to support immediate spark ignition and to reduce the risk of mechanical cutting. 3.3.3 FSM – Fast Spark Monitor This feature ensures smooth and reproducible cutting although the tissue characteristics are varying, e.g. in muscle and fat. 3.3.4 RCAP – Resistance Controlled Automatic Power RCAP is a feature that supports the bipolar mode RFCoag. Deep tissue coagulation without significant desiccation is achieved with RCAP.
17
Product description
Depending on the momentary tissue status, RCAP determines the maximum power uptake of the tissue and automatically adjusts the electrosurgical generator. For this process the geometry of the used bipolar applicator and also the individual tissue characteristics, e.g. blood perfusion, are considered. Therefore, premature tissue desiccation is effectively avoided and it is not necessary to manually adapt the power settings. 3.3.5 Automatic end of procedure detection Certain bipolar coagulation modes are supported by an automatic end of procedure detection. When coagulating tissue the electrical resistance of the tissue increases. Tissue resistance is continuously measured by the electrosurgical generator so that it is able to detect when coagulation is completed. As soon as a limited value of tissue resistance is exceeded, the electrosurgical generator automatically stops the HF output. Depending on the mode, the end of procedure is indicated by a special end tone.
