Extension power cable, Y-type. Measures for avoiding the risk NOTE Nature, source and consequences of the hazard (risk of property damage). Prerequisite for an activity. Activity with one step 1. Activity with several steps in strict sequence 2. 3. ? Result of preceding activity. List (first level). List (second level) Emphasis Emphasis., see Section “xxx”, page xxx Cross reference. The key advantages of this method are: Application does not involve contact, so there is no adhesion of tissue or other material to the electrodes leading to degradation of effectiveness (in contrast to conventional electrosurgery). The maximum penetration depth of the coagulation effect is 3 mm, and it is evenly distributed over the coagulated surface. This reduces the risk of penetration of thin-walled structures. http://www.met-axa.ro/img/uploads/bradysoft-manual.xml

Smoke generation is significantly reduced, which particularly in endoscopic applications improves visibility and leads to shorter surgery times. Carbonisation of tissue is avoided, which facilities better wound healing. With the aid of suitable electrodes, argon-assisted cutting is also possible. The main advantage of this is reduced smoke formation. The ARC PLUS argon device is used in combination with the ARC 350 (900-351) or ARC 400 (900-400) HF generator for cutting and coagulation in open and endoscopic surgery. The following are suitable application areas. General surgery ? Gynaecology ? Casualty surgery ? Plastic and reconstructive surgery. Gastroenterology ? Laparoscopy ? Thorascopy ? Bronchoscopy The argon coagulation unit should not be used if, in the opinion of an experienced physician or according to current professional literature, such use would endanger the patient, due for example to the general condition of the patient, or if other contra-indications are present. Trimming stents with argon coagulation is contraindicated. BOWA presumes that the argon and HF devices are operated under the supervision of qualified or authorised personnel. The surgeon and the medical staff must be trained in the fundamental principles, rules for use and risks of HF surgery and must be familiar with these in order to safely and reliably avoid putting patients, staff and equipment at risk. Contact your BOWA dealer if there is a need for training or training documents. Observe the instructions on electromagnetic compatibility (see Section “EMC”, page 43). ? Always connect the HF device to a mains power system with a protective earth lead in order to prevent electric shock. NOTE The ARC PLUS device may only be operated with the ARC 350 (REF 900-351) and ARC 400 (REF 900-400) HF generators with software version 1.0.0.4.16.8 or later. Additional devices connected to electrical medical devices must satisfy relevant IEC or ISO standards (e.g. http://www.drupalitalia.org/node/73171

IEC 60950 for data processing devices). Furthermore, all configurations must comply with the standard requirements for medical systems (see IEC 60601-1-1 or Section 16 of the third edition of IEC 60601-1, as relevant). Anyone who connects additional devices to medical electrical devices is perforce a system configurator and therefore responsible for meeting standardised system requirements. Please note that local laws prevail over the aforementioned standard requirements. In case of questions, please contact your local dealer or service centre (see Section “Technical service”, page 39). NOTE Impairment of other devices. Electromagnetic interference fields are generated during normal use of the argon device. ? Ensure that no electronic devices that may be impaired by electromagnetic fields are placed in the vicinity of the argon and HF devices. The following measures are advisable. Ensure that only argon gas with purity grade 4.8 or better is used. ? All connected instruments must be purged with argon gas before use. ? Close the gas bottle(s) after every use. Refill gas bottle in accordance with applicable national standards. 2.3. Personal safety instructions 2.3.1. Ambient conditions. Do not operate the HF device in the immediate vicinity of the patient. Observe the minimum distances recommended by BOWA, as shown in the following figure. This applies in particular to surgery in the thorax region. ? Observe the corresponding instructions in the operating manual for the HF device. ? Attach the HF neutral electrode close to the operating field. ? Set the demand pacemaker to a fixed frequency. ? Ensure that the pacemaker does not come into contact with the HF electrode. ? Keep a fully operational defibrillator within reach. ? Carry out a postoperative pacemaker check. 2.3.3. Patient preparation. To avoid emphysemas, do not insert the electrodes into tissue or open vessels, or apply them directly to tissue or open vessels. ? http://forgottenjustice.com/images/bovie-change-a-tip-manual.pdf

Always keep the distal end of the electrode visible during surgery. ? Due to the monopolar operating mode, the HF current flows through the patient’s body to the neutral electrode. For this reason, always ensure that no thermal damage occurs to nearby tissue structures with a tendency to increased local current density. ? In the case of gastrointestinal surgery, the endogenous gases must be securely removed by purging before and during surgery. ? Position the patient so that the patient is not touching any metal parts that are grounded or have considerable capacitance relative to ground (e.g. operating table brackets). See Section “Disinfection and cleaning”, page 36. ? Never immerse the device in water or cleaning agents. ? Never use automatic equipment to disinfect the device. ? Immediately drain any fluid that may have penetrated the device. This interference can be largely eliminated by suitable grounding and screening. 14 ? Always ground the argon and HF devices via the equipotential bonding terminals (e.g. to the equipotential rail of the equipment trolley). Connect the equipotential rail of the equipment trolley to the equipotential rail of the operating theatre, This will minimise interference to other electronic devices from the argon and HF devices. ? Do not place any equipment other than the ARC 350 or ARC 400 HF generator on top of the argon device. ? HF voltages are present during argon-assisted electrosurgery. Orderly insulation of all probes, electrodes, wiring and cables with respect to the HF generation being used must therefore be verified before each use. Connect the device directly to the AC mains. ? Caution: To avoid the risk of electric shock, always connect the device to a supply network with a protective earth lead. ? If the ARC PLUS forms part of a medical electrical system, the requirements in Section 16 of IEC 60601-1:2005 must be observed. ? http://www.megasaludips.com/wp-content/plugins/formcraft/file-upload/server/content/files/16274bb64f38b9---brother-he-240-user-manual.pdf

If a medical electrical system is formed with the ARC PLUS by use of a multiple socket-outlet as a separate unit, a warning must be present to indicate that this multiple socket-outlet may not be placed on the floor. ? Avoid using multiple socket-outlets. ? Do not use any additional multiple socket-outlets or extension cables. ? Always ensure that the installation conforms to the allowable limits for leakage current and protective earth lead resistance. These limits may be exceeded if several devices (medical and non-medical) are connected to a multiple socket-outlet. The totality of devices connected to a multiple socket-outlet form a system and must be regarded as a unit. ? If a multiple socket-outlet is powered from an isolation transformer, ensure that no part of the system is at the same time powered from the regular supply mains, as otherwise galvanic isolation will no longer be present. ? If a multiple socket-outlet not powered from an isolation transformer is used, connections to devices used for medical purposes must only be possible with the aid of a tool. 2.4.2. Correct use of the argon device Endoscopic use In laparoscopic surgery the argon entering the body cavity increases the abdominal insufflation pressure (CO2), unless a suitable arrangement to compensate for the pressure rise is provided. ? We recommend using an insufflator with pressure monitoring. ? To prevent potential damage to the camera optics, do not aim the argon plasma jet at the camera chip. 2.4.3. Correct connection and use of the argon gas bottle. Observe the safety instructions of the gas supplier. For this reason, always check connections for leaks if you hear a persistent hissing sound. ? Do not use leaky gas bottles, pressure reducers or pressurised gas lines. ? Do not apply any lubricants to the pressure reducer, and do not use any tools for assembly. ? Up to two gas bottles can be connected using pressure reducers. http://www.65doctor.com/upload/admin/files/canon-ir-7200-service-manual.pdf

Connecting a pressure reducer with an electronic pressure sensor and a second pressure reducer without an electronic pressure sensor to the same device is not possible. If the output power is not sufficient with the customary settings, first ensure that:.This energy generates electromagnetic radiation. Argon interconnect cable for rigid or flexible argon electrodes. Rigid or flexible argon electrodes. Two fibre optic cables. HF generator, including Argon option. This can adversely affect other devices. ? Ensure that no electronic devices are placed in the vicinity of the argon and HF devices. Argon and HF devices may only be used in rooms used for medical purposes that fulfil the requirements of DIN VDE 0100-710. Secure the argon gas bottle with the plastic strap provided for this purpose. ? Always place the ARC PLUS device below the HF device. ? The equipment trolley must be positioned outside the operating theatre zone with a potential risk of explosion. Ensure free circulation around the devices. Along with the device configuration, the argon gas purity grade specified by BOWA and the specifications for the maximum inlet pressure must be met. The responsibility for meeting these specifications rests with the hospital maintenance department. ? Connect the HF device and the ARC PLUS device to the equipotential rail with separate cables. ? Use the provided Y extension power cable or a mains power cable of equal quality with the appropriate national mark of approval. ? Connect the power cable of the HF device to the supplied Y extension power cable and connect it to the HF device and the ARC PLUS, and connect to the power cable to the AC mains. NOTE Verify that the actual AC mains voltage matches the rated voltage range specified for the device. ? Connect the two fibre optic cables to the corresponding connectors 6 and 7 of the ARC PLUS and the HF device. This switch must be connected to the rear panel of the ARC generator. ? ? ? {-Variable.fc_1_url-

24 Up to two gas bottles can be connected using pressure reducers (e.g. 900-901). Connect the quick-disconnect coupling on the end of the hose from the pressure reducer to either connector 12 or connector 14 on the ARC PLUS. Always use connector 11 for the electronic pressure sensor of the pressure reducer connected to connector 12. Output 14 corresponds to connector 13. For fault correction, see Section “Detecting and Correcting Faults“, page 34. 1. Connect the sterile filter, the argon interconnect cable and the instruments. 2. Switch on power switch 16 on the rear panel of the ARC PLUS. 3. Switch on the ARC 350 or ARC 400 and select an argon operating mode. Purge the system with argon gas by touching the Purge button. ? The argon device is ready for use. The electronic pressure sensor reports the fill level, which is shown on the display of the associated HF generator (e.g. ARC 400). If the fill level of the bottle is adequate, the surgery can begin. 8. A new gas bottle must be connected when a message appears on the display of the HF device indicating that the argon pressure is less than 30 bar. If a second gas bottle is connected, changeover to the second gas bottle takes place automatically. The purpose of this monitoring function is to ensure that an adequate gas supply is available. The argon device is de-activated automatically when an argon mode is not selected on the HF generator. The operating mode indicator 2 changes from green (Standby) to orange (Sleep). Accessory combinations not mentioned in the operating manual may be used only if they are explicitly specified for the intended use. Performance features as well as safety requirements must always be taken into account. ? The insulation of the accessories (e.g. HF cables and instruments) must be sufficient for the maximum output peak voltage (see IEC 60601-2-2 and IEC 60601-2-18). ? Accessories with defective insulation may not be used. 4.3.1. http://www.investing-in-women.com/wp-content/plugins/formcraft/file-upload/server/content/files/16274bb82aa70a---brother-hl-1240-manual.pdf

Use with flexible argon probes Connect the connection cable with the flexible probe to the monopolar output of the HF device. After the system has been purged with argon gas by touching the Purge button, coagulation can be activated with the blue foot switch. The ARC generator shows the gas flow rate and the fill levels of the argon gas bottles on the display when the HF generator is properly connected to the ARC PLUS. To do this, immerse the tip of the probe in water and press the Purge button. If the equipment is working properly, the emerging gas will form bubbles. Also check the instruments for visible external defects. For information regarding use with flexible argon probes and for recommended settings, see the operating instructions for the instruments. 4.3.2. Use with rigid argon probes Connect a handpiece with suitable electrodes to the monopolar output. After the system has been purged with argon gas by touching the Purge button, the argonassisted cutting or coagulation current can be activated by pressing the yellow or blue finger switch on the handpiece. For information regarding use with rigid argon probes and for recommended settings, see the operating instructions for the instruments. 4.3.3. Using a sterile filter If there is height difference between the argon device and the tip of the electrode, body fluid may reach the argon device. For this reason, a sterile filter (830-050) must be fitted between the argon interconnect cable and the gas outlet connector 1 in order to avoid infections and prevent damage to the argon device. The filter is supplied in sterile condition and is disposable. It may not be reused. ? ? Screw the sterile filter into the gas outlet connector 1. Screw the gas connector of the argon interconnect cable into the corresponding threaded coupling of the sterile filter. 5percent-design-action.com/upload/users/files/canon-ir-6870c-manual.pdf

The argon device performs a new self-test when it is again activated after being switched off for at least 15 seconds or after being in standby mode for at least 8 hours. 4.4.2. Cyclical test during operation During operation, safety-relevant functions and signals are tested cyclically. If serious faults are detected, the argon device switches off and the fault indicator on the display lights up red. For further information, see Section “Detecting and Correcting Faults“, page 34. 5. Operation 5.1. Activation and alarm signals When the purging process is active, the ARC PLUS emits a continuous acoustic signal at a fixed volume. Activation and alarm signals are generated by the HF generator. The volume of the activation signal should be increased as necessary for use in relatively noisy surroundings. Specific working methods or other probes may make adjustments to these settings necessary, at the discretion of the surgeon. A general rule is that coagulation, especially endoscopic, must always be performed in plain view in order to avoid direct tissue contact. Observe the instructions for use of the accessories concerned when selecting setting values. Recommended settings for various argon applicators Using the ARC HF generator in argon modes With argon plasma coagulation, the combination of the spray voltage from the HF generator in the instrument or probe and the argon flow from the ARC PLUS forms a plasma jet. This plasma jet has a broad contact area on the tissue. The coagulation effect is self-limiting both in depth and on the surface. Argon plasma coagulation is primarily used in endoscopy (rigid or flexible). Argon plasma coagulation is also used in open surgery. The coagulation effect is secondary here. This operating mode results in less smoke formation than cutting without argon assistance. The gas status 4 lights up yellow when Cut mode is active. This mode enables precise treatment of the tissue according to the selected energy level. Deep coagulation and effective tissue devitalisation can be achieved with a relatively high energy level. The pulse rate (1, 5 or 10 Hz) depends on the selected Effect level. This controlled application allows homogeneous tissue effects to be achieved. The gas status indicator 4 lights up blue when this mode is active. The following table summarises the recommended parameter settings for the HF device. Always set the power and the gas flow rate to the lowest values necessary for the surgery. The length of the argon probe that is used depends on the length of the endoscope and the location of the surgery in the patient’s body. Generators with Plug’n Cut COMFORT recognise BOWA COMFORT instruments and automatically select the appropriate parameter values. Figure 5-3: Fill level indicators on the ARC 400 display When two gas bottles are connected with two pressure reducers, the gas bottle to be used can be selected in the Argon menu of the ARC 350 or ARC 400. In this case changeover to the spare bottle occurs automatically when the gas pressure in the bottle being used drops below a specific level. The user can recognise this from the indicator on the ARC generator display. If a connected gas bottle is empty, a warning message is shown on the display of the ARC generator and an acoustic signal is emitted. The Purge button 3 on the ARC PLUS blinks red. In this way surgical staff are altered to the need for replacing the empty argon bottle with a full one. This process is required in particular for argon-assisted electrosurgery in the gastrointestinal tract. The flammable or explosive endogenous gases that must be assumed to be present there must always be purged with CO 2 or argon in the endangered intestinal section before activating the HF device and argon coagulation. Pressing the Purge button 3 can also help to remove any tissue deposits in the lumen near the electrode tip. For this reason, purging should also be carried out if the plasma does not ignite. The gas status indicator 4 lights up green during purging. Figure 5-6: 5.6. Purging active and Purge button actuated Post-surgery instructions The procedure described below is recommend after completion of surgery. 5.6.1. Shutting off the argon gas Check the primary gas pressure on the pressure gauge of the pressure reducer. If it is less than 30 bar, exchange the gas bottle. Activation is not possible with a gas pressure below 2 bar. If there is still sufficient pressure in the gas bottle, close the bottle valve by hand to prevent potential gas loss. 5.6.2. Exchanging the gas bottle Close the bottle valve by hand and disconnect the pressurised gas line from gas connector 12 or 14 on the rear panel of the ARC PLUS, and disconnect the electronic pressure sensor (if present) from connector 11 or 13. Then press the pressurised gas line connector onto bleed stub 9 on the rear panel to allow the residual pressurised argon to escape. After this the pressure reducer can be manually unscrewed from the gas bottle and a new bottle can be fitted. Observe the use instructions for the pressure reducer. Ensure that the gas bottle is securely attached to the equipment trolley. The fault indicator 5 lights up red when a serious fault condition is signalled. 6.1. Fault list Visual and acoustic fault indications Fault conditions are indicated by messages on the HF generator along with visual and acoustic signals. Furthermore, in the event of certain faults the generator cancels activation and the system is reset. Visual and acoustic signals: Signal Designation “Output fault” indicator lights up red Acoustic warning signal sounds The following fault messages are displayed by the ARC 400 in combination with the ARC PLUS: 34 Heading Fault message ARC PLUS Fault Please check if the argon bottles are connected and open. Empty bottles should be replaced. If the user of the ARC PLUS requires it to continue operating even in the presence of power interruptions, it is recommended to operate the ARC PLUS from an uninterruptible power supply or a battery. Note: UT is the AC supply voltage prior to the application of the test level. Electromagnetic immunity (IEC 60601-1-2, Table 204) The ARC PLUS is intended for operation in the electromagnetic environment described below. The customer or user of the ARC PLUS should ensure that it is operated in such an environment. Immunity test IEC 60601 Conformity Electromagnetic environment guidelines test level level Conducted HF 3 V rms 10 V Portable and mobile wireless devices should not be interference as used within the recommended protective distance from 150 kHz to specified in the ARC PLUS and its cables, which is calculated using 80 MHz IEC 61000-4-6 the formula appropriate to the relevant transmission frequency. The field strength of stationary transmitters as a determined by on-site measurements should be lower b than the compliance level at all frequencies. Interference is possible in the vicinity of devices bearing the following symbol: 44 Note 1 The higher frequency range applies in case of 80 MHz and 800 MHz. Note 2 These guidelines may not be usable in all cases. The propagation of electromagnetic waves is influenced by absorption and reflection by buildings, objects and people.An EMC site survey with regard to stationary transmitters should be considered in order to determine the effect of their electromagnetic transmissions. If the measured field strength at the location where the ARC PLUS is used exceeds the aforementioned compliance level, the ARC PLUS should be monitored to verify proper operation. If unusual behaviour is observed, additional measures may be necessary, such as changing the orientation or location of the ARC PLUS. The customer or user of the ARC PLUS can help to prevent electromagnetic interference by complying with the minimum distance between portable and mobile HF telecommunication devices (transmitters) and the ARC PLUS. These distances depend on the output power of the communication device as listed below. Note 1 The higher frequency range applies in case of 80 MHz and 800 MHz. The propagation of electromagnetic waves is influenced by absorption and reflection by buildings, objects and people. 13.
