Safety information

An insufficient understanding of the safety information in these instructions for use can result in death, serious injury, or equipment damage. Liquids and splashes If liquids get into the electrosurgical generator, there is a risk of electric shock and damage to the product. Environmental conditions Inappropriate environmental conditions during use, storage or transport can damage the electrosurgical generator and its accessories. Vibration and shocks Vibrations and shocks during use, storage or transport can damage the electrosurgical generator and its accessories. Appropriate power supply and grounding If the electrosurgical generator is improperly connected to the mains electricity there is a risk of electric shock. Potential equalization The purpose of additional equipotential bonding is to equalize potentials between different metal parts that can be touched simultaneously in the medical environment. Equipotential bonding increases the electrical safety. Compatible equipment Using incompatible equipment can lead to excessive or incorrect HF output. This can result in injury to the patient and the user as well as damage to the products. Secure connection of the plugs All plugs must be securely inserted to the corresponding sockets. Be aware that the electrosurgical generator immediately turns off if the mains plug is accidentally disconnected. During a procedure, this can result in complications for the patient. If the foot switch plug is not connected securely, then the HF output may not be activated. There is the risk that the HF instrument cuts tissue mechanically. This can result in bleeding and perforation of the tissue. Electromagnetic compatibility During activation of the electrosurgical generator, high frequency signals or spark discharge noise can disturb neighboring electrical equipment. Malfunction of the devices can occur, e.g. the monitor of endoscopic imaging equipment can freeze or black out. The precautionary measures are described in the chapter “18 Electromagnetic compatibility” on page 132. Additionally, the instructions regarding installation and connection in the following chapters must be observed. Damaged equipment and accessories The use of damaged equipment, of equipment with improper functioning or the reuse of single use products can cause electric shock, mechanical injury, infection and thermal injury to the patient and the user. Procedural hazards and complications If a malfunction of the electrosurgical generator occurs during the procedure, there is the risk that the procedure is interrupted, delayed or cannot be completed. A prolonged use or an energy dosage more than necessary can compromise the patient safety.

Safety information

Disconnection of cables Tugging and pulling on the cables can break the electric circuit and can damage the equipment. Maintenance To ensure electrical safety and to maintain device performance, Olympus recommends to perform a safety check annually or according to national regulations and guidelines on all medical electrical equipment. Responsibility of the user In electrosurgery, electric current is applied to a patient to modify, destroy, dissect or remove tissue. This method bears certain risks for the patient, the operator and the assisting medical personnel. It is important that all users are aware of such risks. The information in the following sections summarize important basics and rules of electrosurgery to remind the operator and the medical personnel of the associated risks. This information is not meant to replace the fact that the all users need to have a profound understanding of electrosurgical procedures. 2.3.1 Fire and explosion Sparks that are generated in most electrosurgical procedures can ignite surroundings, substances and materials. Fire and explosion can occur. Flammable anesthetics and fire supporting gases Especially consider: ‒ Flammable anesthetics or oxidizing gases, e.g. nitrous oxide (N₂0) or oxygen ‒ Volatile solvents, e.g. ether or alcohol Flammable agents for cleaning and disinfection Non-flammable agents should be used for cleaning and disinfection wherever possible. If flammable agents are used, they should be allowed to evaporate before the application of HF surgery. There is a risk of pooling of flammable solutions under the patient or in body depressions such as the umbilicus, and in body cavities such as the vagina. Any fluid pooled in these areas should be mopped up before HF surgical equipment is used. Flammable gases in the gastrointestinal tract/endogenous gases When performing electrosurgery in the gastrointestinal tract, flammable gases can be present in the intestines. Attention should be called to the danger of ignition of any endogenous gases. Flammable materials An active electrosurgical instrument or an instrument that is still hot from use can cause fire when in contact with flammable materials, e.g. gauze, surgical drape or body hair. 2.3.2 Electrosurgical smoke The thermal destruction of tissue creates a smoke by-product. This smoke can contain toxic gases and vapors such as benzene, hydrogen cyanide, formaldehyde, bioaerosols, dead and live cellular material (including blood fragments) and viruses. ‒ At high concentrations the smoke causes ocular and upper respiratory tract irritation. ‒ The smoke creates visual problems for the surgeon. ‒ The smoke has been shown to have mutagenic potential.

12

Safety information

‒ The smoke has unpleasant odors. Olympus recommends to take adequate measures during the procedure to protect the surgical staff from inhaling unfiltered smoke, e.g. by using smoke evacuators, sufficient ventilation in the operating room or wearing surgical masks. 2.3.3 Effects of electric current on biological tissue Electrolytic effect – undesired When direct current (DC) is applied to biological tissue, spatial separation of positive and negative ions occurs. This produces acids and bases at the electrode poles and results in acid burns to the tissue. Therefore, only alternating current (AC) is used for electrosurgical procedures. Faradic effect or neuromuscular stimulation – undesired Alternating current (AC) that is provided by the mains electricity has a frequency of approximately 50 to 60 Hz. Electric current at such a frequency has undesired effects to the human body like pain, nerve stimulation, muscle stimulation or cardiac arrest. As the human body is less sensitive to current with high frequencies, electrosurgical generators transform the low frequency AC provided by the mains electricity to high frequencies of above 300 kHz, i.e. high frequency current or HF current. However, due to high current densities, low frequency currents can still arise when using an electrosurgical generator. Reasons for this phenomenon are, e.g.: ‒ Spark discharge to the tissue or to other metallic objects ‒ High HF output settings ‒ The use of modes with HPCS (High Power Cut Support), see the section “7.4 Description of modes” on page 55. Therefore, its important to be aware that neuromuscular stimulation - which can cause pain and discomfort to patients without sedation, pain medication or general anesthesia - can occur during electrosurgery. Thermal effect – desired When the applied HF current flows through the tissue and needs to overcome its electric resistance, heat is generated within the tissue. In other words, it is not the metal part of the electrosurgical instrument that heats the tissue, it is the electric current that flows within the tissue. This thermal effect of the electric current on tissue is used for cutting and coagulating. Depending on the specific resistance of different tissue types, the thermal effect varies. The higher the tissue resistance is, the less amount of current can flow through the tissue and the smaller the desired thermal effect is. Basically, tissue that has a high water content has a low resistance and therefore the thermal effect is high. Some examples of specific resistances in different tissue types: ‒ Muscle: 160 to 250 Ω/cm ‒ Blood: 160 to 300 Ω/cm ‒ Liver: 200 to 380 Ω/cm ‒ Brain: 670 to 700 Ω/cm ‒ Fat: 1,600 to 3,300 Ω/cm ‒ Skin: 11,000 Ω/cm Compared to metals, e.g.: ‒ Copper: 0.0000017 Ω/cm

13

Safety information

‒ Silver: 0.0000016 Ω/cm 2.3.4 Electrosurgical effects – coagulation, cutting and carbonization Coagulation A temperature of 60 to 70 °C in the area around the active electrode gradually heats the tissue cells until their intracellular fluid escapes through the cell membranes. The results are: ‒ Protein denaturation ‒ Shrinking of the cells ‒ Shrinking of vessels ‒ Clotting of blood ‒ Hemostasis Cutting When the generated heat causes the intracellular fluid to rapidly evaporate, then this results in an explosive burst of the cell membrane. To achieve this, a very high voltage of approximately 200 Vp is required. Such a high voltage generates sparks between the tissue and the active electrode. These sparks concentrate the HF current to specific points of the tissue that heats up to more than 100 °C. The fast repetition of this effect around the active electrode determines the cut.

Principle of an electrosurgical cut It is important to understand that the sparks are only able to ignite repetitively if the active electrode is not in direct contact with the tissue. The desirable side effect of electrosurgical cutting is the hemostasis of neighboring tissue cells, as part of the heat is transferred to surrounding tissue where coagulation takes place. Risk of mechanical injuries To avoid the risk of mechanical cuts by the metallic tip, blade or snare of an HF instrument it is important to keep in mind that it is the HF current that performs the desired cut. If too much mechanical stress is applied to the target tissue, e.g. by a loop that is fastened to strongly around the target tissue, then bleeding or perforation can occur.

14

Safety information

Carbonization – particularly undesirable Carbonization is the overheating of desiccated tissue. The remains of the tissue cells are reduced to carbon. Carbonization of tissue takes place from approximately 200 °C upwards. It is important to understand that tissue carbonization must be avoided as it impairs the wound healing. 2.3.5 The electric circuit Three important rules of electricity When working with electric energy the following 3 basic rules must be respected: ‒ Electric current needs a complete circuit to flow. ‒ Electric current is ‘lazy’ and prefers the path of least resistance. ‒ Electric current seeks ground. The circuit of electrosurgical HF current In electrosurgery the complete electric circuit consists of: ‒ The electrosurgical generator ‒ A monopolar or bipolar electrosurgical instrument for cutting or coagulation ‒ The patient’s target tissue ‒ For monopolar procedures: a neutral electrode ‒ The connecting cables 2.3.6 Monopolar electrosurgery

NEUTRAL

In monopolar electrosurgery the HF current passes from the active electrosurgical instrument through the patient to the neutral electrode and back to the electrosurgical generator to complete the electric circuit. High current densities and thermal effect at the instrument’s tip The electrosurgical instrument usually has as pointed shape with a small surface. Therefore, a high current density accumulates at the instrument’s tip which generates enough heat for cutting or coagulating the target tissue. Low current densities and thermal effect at the neutral electrode The neutral electrode has a large surface so that the current is spread over a large area. This reduces the current density and the heat. As the electric current always takes the path of the lowest resistance, the neutral electrode ensures that the current returns to the electrosurgical generator without causing overheating of tissue outside the surgical site.

15

Safety information

The entire surface of the neutral electrode must be reliably attached to the prepared patient’s skin, usually on the thigh. Neutral electrodes Wrong application, wrong size or malfunction of the neutral electrodes are the main causes for endogenous burns. ● Observe the information in the chapter “6 Safe use of neutral electrodes” on page 44. 2.3.7 Bipolar electrosurgery For surgical procedures where the HF current could flow through parts of the body that have a relatively small cross sectional area, the use of bipolar techniques can be desirable to avoid unwanted tissue damage.

NEUTRAL

In bipolar electrosurgery no neutral electrode is required. Bipolar electrosurgical instruments are designed in a way that the current passes only between the 2 electrodes that are implemented within the same device, e.g. between the jaws of a bipolar forceps. In bipolar electrosurgery the current does not pass large areas of the patient’s body but only through the tissue that is between the two electrodes within the electrosurgical instrument. The bipolar technique makes electrosurgery much safer, because: ‒ The current exposition to the patient is limited. ‒ There is no risk of burns caused by the neutral electrode. Refer to the section “6 Safe use of neutral electrodes” on page 44. ‒ The risk of leakage currents is reduced. Refer to the section “2.3.9 Unintended current flows” on page 17. 2.3.8 Implants Electronic implants like cardioverter defibrillators, cardiac pacemakers or cochlear implants are very sensitive to electric energy. Therefore, electrosurgical procedures can interfere with and can damage such devices. Also other electrically conductive implants like metal implants present a hazard due to concentration or re-direction of HF currents. Qualified advice should be obtained before the electrosurgical procedure.

16

Safety information

2.3.9 Unintended current flows Physiological monitoring equipment When using physiological monitoring during an electrosurgical procedure, current can flow to the monitoring electrodes. To prevent the risk of high current densities, the monitoring electrodes need to be placed as far as possible from the surgical electrodes (instrument, neutral electrode). Especially monitoring electrodes in form of needles bear a high risk of burns at the site where the electrodes are attached. Therefore it is recommended to not use needle monitoring electrodes. In any case it is recommended to use monitoring equipment with HF current limiting measures. Conductive fluids within the patient Conductive fluids within the patient, like blood or saline, that are in direct contact with or in close proximity to the active instrument can transmit electric current and heat to non-target tissue. This can cause unintended burns to the patient. Earth leakage currents Unfortunately, alternating HF current techniques always correspond with a certain level of earth leakage currents. Earth leakage currents are current flows that pass another pathway than the initially intended electric circuit. A certain percentage of the current could pass via the patient and the operating table or the surgeon and then via the ground back to the electrosurgical generator. Earth leakage currents bear the risk of thermal tissue damages. Olympus electrosurgical generators constantly monitor earth leakage currents and give an acoustic and visual feedback if the earth leakage current exceeds a certain level. These feedbacks make the physician aware that there is an increased risk of burns for the patient. The user must not touch the patient and any contacts in the sockets simultaneously. Capacitive coupling

Another phenomenon of electricity is that alternating HF current can pass from a conductive material through an insulator into another nearby conductive material without the aid of wires or cables. This can occur despite intact insulation surrounding the conductors and is called capacitive coupling. So it is possible e.g. that the HF current passes via the insulation of an active electrosurgical instrument to a metallic trocar which is in contact with some tissue in the bowel. If the contact area is small so that the current density is high, then this can result in a burn to the bowel tissue. Capacitively coupled currents mainly occur in monopolar electrosurgery. They are also called leakage currents or stray currents.

17

Safety information

Direct coupling

Direct coupling is the current flow directly from one conductor to another conductor. For example, when an active electrosurgical instrument like a cutting electrode is in contact with another metallic instrument, like a grasping forceps. Then current flows from the active cutting electrode into the grasping forceps and the grasping forceps can cause burns to nontarget tissue. For endoscopic surgery it is important to understand that the electrosurgical instrument must only be activated when the conductive (non-insulated) part of the active electrode is in full view. Insulation failures

When the insulation of an electrosurgical instrument or of an HF cable is damaged the electric current can pass another way than the intended way. If the insulation is damaged, another metal instrument can be activated or non-target tissue inadvertently can be burned.

The ESG‑410 is activated either via a compatible foot switch or via a hand switch at the connected instrument. The ESG‑410 is connected to the local power supply. Details on the hardware and software, on the correct handling and use of the device are described in the following chapters. 3.2.2 Features The electrosurgical generator is equipped with the following features: ‒ Contact Quality Monitor (CQM) ‒ High Power Cut Support (HPCS) ‒ Fast Spark Monitor (FSM)

19

Product description

CQM – Contact Quality Monitoring for the neutral electrode When using split type neutral electrodes for monopolar electrosurgery, the ESG‑410 is able to detect unintended detachment of the neutral electrode from the patient. The indicator for the contact quality monitor (CQM) is 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 is red. Using non-split type neutral electrodes is not as safe as using split type ones. 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 the chapter “6 Safe use of neutral electrodes” on page 44. HPCS – High Power Cut Support This feature optimizes the start of the cutting procedure for certain cutting modes. By applying high power to the tissue, HPCS supports immediate spark ignition and reduces the risk of mechanical cutting. FSM – Fast Spark Monitor When using cutting modes this feature ensures smooth and reproducible cutting although the tissue characteristics are varying, e.g. in muscle and fat.
