Principles and Intended Use 2.1 Monopolar Operation The HF electrosurgical unit ME MB1 is a generator that converts the electric energy supplied by the mains into a high-frequency current. Via a supply lead, this HF current is then led to a handle before reaching the dot-shaped active electrode. Where the electrode is applied – in the tissue surrounding the point of contact – a high field density is generated. It is this high energy concentration which produces the desired electrosurgical effect in the area around the active electrode. Subsequently, the current flows through the patient's body up to the large neutral electrode. This is accompanied by a further reduction in current density. Thus, if used as intended, this method ensures that no thermal effect is produced in the region where the neutral electrode is attached. The circuit is then closed via the neutral electrode’s connecting cable (lead). The HF generator can be activated by the user either with the foot switch or with the finger switch provided on the surgeon's handle. 2.2 Bipolar Operation Thanks to a special design (insulation), it is possible to build bipolar instruments in which the active electrode and the neutral electrode are located directly opposite each other. This means that the HF current travels only a very short path, just from one tip of the instrument to the other. As a result, coagulation areas are highly limited while power requirements remain low. 2.3 Intended Use The ME MB1 is an electrosurgical generator designed for the electrosurgical cutting or coagulating of living human or animal tissue.

This symbol means ATTENTION! REFER TO OPERATING INSTRUCTIONS WARNING - HIGH FREQUENCY CURRENTS HIGH VOLTAGE! V 2.1 7 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 3.2 Mains Connection Before switching on the unit for the first time, please verify that the mains voltage corresponds to the voltage indicated on the “power” label (next to the power cable connector socket). If the voltage differs, please inform your KLS Martin contact partner directly. If change-over to a different mains voltage should be necessary, this work must be performed by a person specially authorized by Gebrüder Martin! The unit may never be opened by unauthorized persons! The device is obtainable in 2 versions: 100–127 VAC, T 8 A (8 A slow-blow.) 220–240 VAC, T 4 A (4 A slow-blow.) Connect the unit to the power supply system, then set the power switch located on the front panel to “Ι”. 3.3 ON ( Ι ) / OFF ( Ο ) After switching on the unit with the power switch (1), the system is started and performs an initial self-test. 3.4 Self-Test When the unit is switched on, it executes a self-test: The keys for the five current modes light up one after the other. The subsequent lighting up of all five current mode keys together, accompanied by an acoustic signal, indicates the successful end of the self-test. The unit is operative. Without these final signals, the unit is defective. The KLS Martin service technician has to be informed. 3.5 Monopolar Operation 3.5.1 Connecting the neutral electrode If the neutral electrode is missing (not connected), the red NE indicator light (18) starts flashing. In this condition, the HF current cannot be activated. Any attempt in this direction – by pressing the finger button or foot switch – triggers an additional acoustic alarm signal. If a multi-surface (two-part) electrode is connected, the indicator light (18) will go out only after the electrode has been properly and securely applied. Since response times may differ, this may take some time and should be taken into account when using such an electrode. 8 V 2.1 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 3.5.2 Connecting the handles For monopolar cutting and coagulation, either a handle with finger switches or a foot switch plus a handle without finger switches can be connected. Handles with finger switches can be connected to output (17). Handles without finger switches as well as surgical instruments (such as resectoscopes) are also connected to output (17). The corresponding foot switch must be connected to socket (16). Socket (17) allows the connection of handles with coaxial plugs as well as handles with 3-pin plugs. For further details, please refer to the KLS Martin Accessories Catalog. Surgical HF instruments without a switching function, such as resectoscopes, must be connected to the right-hand (coaxial) jack of output (17), as the foot switch only works on this socket. The selected active electrode must be inserted into the hexagonal socket of the surgical handle until it engages. This prevents rotation of the electrode during use. Warning • Never activate the high-frequency current when inserting or exchanging electrodes! 3.5.3 Selecting the desired type of current In the yellow “monopolar cutting” section of the control panel (front), three different types of current are available: Cutting 1 Smooth cut with no scab formation Cutting 2 Cutting current with some/little scab formation ENDO Endo-mode Time-controlled cutting mode enabling a fractionated and thus controlled cut for special applications, e.g. endoscopic papillotomy and endoscopic polypectomy. This mode is characterized by a short but intensive pulse at the start of the cutting process, combined with a coagulating effect that is strong enough to achieve hemostasis. As this pulse is repeated at regular intervals, it is ideal for removing pedicled tumors (also called polyps) on an endoscopic basis – using the diathermy loop electrode for example. V 2.1 9 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode In the blue “monopolar coagulation” section of the control panel, two different types of current are available: Contact coagulation For deep coagulation through direct contact between the electrode and the tissue Spray coagulation / fulguration High-voltage coagulation current for surface coagulation. Especially suitable for hemostasis in TUR, using small-surface instruments (e.g. loop electrodes) 3.5.4 Setting the output power Setting the output power for cutting is done with the power control switch (6). For coagulation, the control switch (10) must be used. Adjustment is possible between a preset minimum value and a maximum value depending on the selected type of current (see Technical Specifications). The characteristic line allows fine adjustment in the lower range, while the upper power range is characterized by a uniformly linear increase. This enables high-precision dosage in the lower range without any need for special functions, which is particularly useful in difficult operations, while sufficient reserves are guaranteed in cases where a high power output is required. Please note that this special feature means that the mid-position of the power control switch is of course not equivalent to half the output available. PLEASE NOTE: In the lower control range of the power control switch, the power output is not precisely defined. Therefore, the unit should not be used in this output range. 1 350 300 2 Ausgangsleistung 250 3 200 150 4 100 50 Output power in watts Output power in watts 400 100 1 80 60 40 20 0 1 2 3 4 5 6 7 Einstellung 8 9 10 0 1 2 3 Setting 1 2 3 4 10 = = = = Cutting 1 Cutting 2 Contact coagulation Spray coagulation 4 5 6 7 8 9 10 Setting 1 = Endo-mode V 2.1 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 3.5.5 Operation To activate the HF current, either the yellow button of the handle or the yellow pedal of the foot switch must be used if you have selected a cutting current. The blue button/pedal, in turn, activates coagulation currents. In either case, the HF current output depends on the preset types of current and the selected power settings. As soon as the handle button is pressed or the appropriate foot switch pedal operated, the selected working channel is activated. At the same time an acoustic signal is heard (different for cutting and coagulation) and the corresponding indicator lamp lights up. If HF current activation exceeds a period of 15 seconds, the acoustic signal grows louder. Please note! If you want to use the foot switch in monopolar operation, the (monopolar) switch-over button (15) for the blue foot switch pedal must first be activated. If, in contrast, the (bipolar) switch-over button (14) is active, the bipolar HF output will be activated when the blue foot switch pedal is operated! The yellow foot switch pedal always activates monopolar cutting current, irrespective of the switch-over buttons. The handle switches always activate monopolar currents, irrespective of the switch-over buttons. Warning • The safety guidelines for the patient and the operator of HF surgical devices as listed in Section 4 (“Safety Instructions”) must always be duly observed. Special attention must be given to a safe application of the neutral electrode and correct placement of the patient. • If two controls (e.g. the blue and yellow buttons of the handle) are pressed simultaneously, the generator will be blocked. No high-frequency power is available in this case. • The surface of the unit may heat up strongly if HF current is applied at a high power setting for an extended period of time. • The rated minimum voltage of accessories used must match the voltage values indicated in Section 8.1. • Only accessories that are in a perfect working condition may be used! 3.5.6 Functional test Before using the unit, all of its functions must be checked. Please carry out the following tests: 1. Withdraw the plug of the neutral electrode's connecting cable from the socket (19). The red alarm light (18) must start blinking. Try to activate the HF current. An acoustic alarm signal must now be heard and HF current activation must be blocked. 2. Reinsert the plug of the NE connecting cable into the socket (19). The red warning light (18) must stop flashing now. V 2.1 11 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 3. Connect the connecting cable of the electrode handle to socket (17). Activate the different currents by operating either the finger switch on the electrode handle or the foot switch. The indicator lights (2), (7) or (11) must now light up in accordance with the selected type of current and the HF current activation signal must be audible. Warning • If you hear the HF current activation signal with no foot switch or electrode handle connected to the unit, then the unit is defective and must not be used. A technical inspection is required in this case. • If you hear the HF current activation signal with the foot switch or electrode handle connected to the unit but not operated, then the foot switch or the handle is defective and may not be used anymore. Replace immediately! 3.6 Bipolar Operation 3.6.1 Neutral electrode function No neutral electrode is required for bipolar applications. In this operating mode, therefore, the bipolar HF generator can be activated despite the flashing of the neutral electrode indicator light (18). However, since alternation between bipolar and monopolar application is usually required during the course of an operation, we recommend you to apply the neutral electrode nonetheless. 3.6.2 Foot switch operation The features of the KLS Martin ME MB1 also include bipolar coagulation. The following accessories can be connected: Bipolar coagulation Any bipolar connecting cable featuring a small coaxial plug (e.g. different bipolar forceps) can be connected to socket (13). The bipolar coagulation function is activated with the foot switch. In order to be able to activate bipolar coagulation current, the blue pedal of the foot switch must first be switched to the bipolar HF generator. For this, press the button (14) so that it will light up. This setting will be retained also if the unit is switched off. Please note that if the (monopolar) switch-over button (15) has been activated, the monopolar HF output will be activated when operating the blue foot switch pedal! The yellow foot switch pedal always activates monopolar cutting current, irrespective of the switch-over buttons. The handle switches always activate monopolar currents, irrespective of the switch-over buttons. 12 V 2.1 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 3.6.3 Adjusting the output power Setting the output power for bipolar coagulation is done with the power control switch (12). Adjustment is possible between a preset minimum value and a maximum value (see Technical Specifications). The characteristic line allows fine adjustment in the lower range, while the upper power range is characterized by a uniformly linear increase. This enables high-precision dosage in the lower range without any need for special functions, which is particularly useful in difficult operations, while sufficient reserves are guaranteed in cases where a high power output is required. Please note that this special feature means that the mid-position of the power control switch is of course not equivalent to half the output available. PLEASE NOTE: In the lower control range of the power control switch, the power output is not precisely defined. Therefore, the unit should not be used in this output range. 90 80 70 Ausgangsleistung Output power in watts 100 60 50 40 30 20 10 0 1 2 3 4 5 6 Einstellung 7 8 9 10 Setting Bipolar coagulation 3.6.4 Operation The blue pedal of the foot switch (14) must be switched to the “bipolar coagulation” type of current! Accordingly, the bipolar coagulation current is activated upon operating the blue foot switch pedal. The HF current output is determined by the selected power setting. Upon activating the current, an acoustic signal is heard and the corresponding indicator light (11) lights up. If HF current activation exceeds a period of 15 seconds, the acoustic signal grows louder. Warning • The surface of the unit may heat up strongly if HF current is applied at a high power setting for an extended period of time. V 2.1 13 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 3.6.5 Functional test Before using the unit, all of its functions must be checked. Please carry out the following tests: 1. As described in Section 3.6.1, we recommend connecting the neutral electrode also when using the bipolar method, although this operating mode as such requires no dispersive electrode. So if you choose to connect the neutral electrode, please perform the following test: Withdraw the plug of the neutral electrode's connecting cable from the socket (19). The red alarm light (18) must start blinking. Try to activate the monopolar HF current. An acoustic alarm signal must now be heard and the activation of the monopolar HF current must be blocked. 2. Reinsert the plug of the NE connecting cable into the socket (19). The red alarm light (18) must stop flashing now. 3. Connect the connecting cable of a bipolar coagulation instrument to jack (13). 4. Press the button (14) to assign the “bipolar coagulation” current to the blue pedal of the foot switch. 5. Operate the foot switch to activate the “bipolar coagulation” current. The indicator light (11) must light up now and the HF activation signal must be sounded. Warning • If you hear the HF current activation signal while the foot switch is disconnected, then the unit is defective and must not be used. Be sure to have the unit checked and repaired in this case! • If you hear the HF current activation signal with the foot switch connected but the blue pedal has not been operated, this means that the foot switch is defective and must be replaced! 4 Safety Instructions 4.1 General Information Electrosurgical units are high-frequency generators that produce high voltages and high currents so they can carry out their intended purpose. To avoid any hazards to the patient, the operating staff or other persons, the method described below should be carefully followed and the operating and safety instructions be strictly observed. 4.2 Placing the Patient Correctly The patient must be well insulated from grounded metal parts. It is particularly important to ensure that the patient’s extremities cannot come in contact with metal parts. If the patient is placed on an operating table, then he/she must be well insulated against high frequencies by using enough intermediate layers (covering towels). As moisture, sweat or the 14 V 2.1 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode like is likely to accumulate during the operation, a watertight sheet must be used to maintain the insulating properties of the intermediate layers and prevent them from getting wet. Under any circumstances, make sure that no liquids collect under the patient. If necessary, use additional dry towels as intermediate layers. All areas where sweat tends to accumulate – e.g. where the extremities touch the body or there is skin-to-skin contact – should be kept dry by placing enough covering towels between them (arm/trunk, legs, breasts). These insulation requirements must be observed also when the patient needs to be repositioned during the operation! 4.3 Attaching the Neutral Electrode Electrodes and cables must be attached carefully. To prevent any hazards, be sure you • attach the neutral electrode on the patient's body as close to the operating site as possible, establishing full contact between the electrode surface and the patient’s skin; • see to it that the neutral electrode remains fully attached as long as the high-frequency current is being used. When attaching the neutral electrode to extremities, don’t impede the blood flow; • guide the connecting cables of the HF electrodes without loops and in such a way that they neither touch the patient nor other cables. This applies especially to the neutral electrode. Use only the cables provided by the manufacturer of the unit; • keep the current paths in the patient’s body as short as possible, making sure that the current flows through the body longitudinally or diagonally but not transversely, especially not in the thorax. Metal parts that may be in or on the body are to be removed, insulated or carefully watched for possible hazards. Whenever the patient is repositioned, be sure to check the electrodes for proper application and the electrode leads for correct routing. Never attach the neutral electrode on implants, other metal parts, bony protrusions/outgrowths or scar tissue. Circumstances may require the cleaning or degreasing of the attachment site; shave areas of abundant hair growth. Never employ agents that dry up the skin (such as alcohol). Don’t remove the neutral electrode by pulling the connecting cable or the connecting clip. Selfadhesive electrodes should be removed very carefully in order not to injure the skin. 4.4 Working with the Active Electrode When using HF currents for surgical purposes, the following rules must be observed: • If a surgical unit and monitoring devices are simultaneously used on the same patient, then only monitoring electrodes having protective resistors or HF chokes incorporated in their connecting cables may be employed. Do not use needle electrodes for monitoring purposes! Moreover, the active surgical electrode should never be used near ECG electrodes (minimum distance: 15 cm). V 2.1 15 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode • The HF power should be kept as low as possible for the particular application. Note: An insufficient effect with the usual setting may be due to a poor attachment of the neutral electrode, bad contact in plug-and-socket connections, broken cables (underneath the insulation) or encrusted electrodes. Be sure to check this; defective accessories must be replaced. 4.5 Further Safety Instructions • When working on body parts with low cross sections, the use of the bipolar technique may be indicated in order to prevent an unintended coagulation in other sites. • Avoid using flammable anesthetics, nitrous oxide (N2O) and oxygen. The use of HF surgical devices is always associated with spark formation at the active electrode. Inflammable materials used as cleaning or disinfecting agents or solvents must be allowed to evaporate before starting HF surgery. Note that there is a hazard of combustible liquids accumulating under the patient or in body depressions like the navel or in body cavities like the vagina. Liquid that has accumulated in such places must be removed before HF surgery takes place. There is also a hazard of igniting flammable endogenous gases! Note that materials saturated with oxygen, such as cotton and gauze, may also be ignited by the sparks produced in the normal use of the HF surgical unit! • Transurethral prostatic resections (TUR): As is well-known, easily inflammable gases can be generated in the course of transurethral prostatic resections (TUR), particularly during uninterrupted or extended HF application. In such a case, the gases tend to accumulate in the upper region of the bladder. If ambient air mixes with those gases, the hazard is still greater, as an accidental explosion might be caused if the HF current comes in contact with the gas mixture. Therefore, see to it that the gas-air bubble inside the bladder is kept as small as possible. • This device may not be used in combination with other systems unless permitted by the manufacturer. • Other electromedical devices may be affected by operating this HF surgical unit. 4.6 Cardiac Pacemakers, Implants As a rule, HF current should never be conducted across a patient’s implants. This must be taken into account when attaching the active and neutral electrodes. So never attach a neutral electrode over endoprostheses! In patients with active implants such as pacemakers or implanted electrodes, there is an additional risk when using HF electrosurgical techniques, as irreparable damage to the active implant or an impairment of its operation can occur. For this reason, the following guidelines should be observed. We recommend monitoring patients with cardiac pacemaker implants, using suitable equipment. A defibrillator and an external pacemaker should be kept ready for use. The output power level of the electrosurgical unit should always be set as low as possible. The active elec16 V 2.1 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode trode of the electrosurgical unit should be operated only at a minimum distance of 15 cm to the implant or its electrodes. Wherever possible, the bipolar technique should be used. All instructions for use, particularly when attaching the neutral electrode, must be strictly observed. 4.7 Guiding the Cables on the Patient If the monopolar and bipolar methods are used jointly, be sure to maintain a minimum distance of 10 cm between the two types of cable. Give the cables enough slack and avoid loops! 4.8 Depositing HF Instruments HF instruments should never be placed on the patient while they are not being used! 4.9 Operation of Two Electrosurgical Units on One Patient As a rule, the use of two electrosurgical units on one patient should be limited to cases where this is necessary for medical reasons, as such simultaneous operation poses an increased risk of unintended burns due to high-frequency leakage currents. The following rules should be observed when working with two electrosurgical units simultaneously: • Be sure to use only type CF electrosurgical units from Gebrüder Martin. • Every HF unit operated in monopolar mode requires a neutral electrode attached separately to the patient’s skin. Be sure to comply with the instructions for correct NE attachment! • No neutral electrode is needed for purely bipolar operation of electrosurgical units. • Regarding the flow of current from the active electrode to the neutral electrode, the expected current paths must not be allowed to cross or superimpose each other. Therefore, the respective neutral electrodes must be attached as close to the surgical site as possible. • The sum total of the simultaneously applied power outputs must not exceed 400 watts. 4.10 Accessories When using accessory equipment, please observe the following: • The accessories used must have sufficient electric strength. The rated minimum voltage of any such product must match the voltage values indicated in Section 8.1. • Be sure to use only accessories that are in a perfect working condition (always check for potential defects!). V 2.1 17 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 5 Safety Checks At least every 24 months, the following checks and tests must be performed on the unit by qualified persons who have the necessary training, knowledge and practical experience to carry out such work responsibly and independently. • Visual inspection: check the unit and its accessories for mechanical and functional damage/defects. • Check all safety-related labels for legibility. • Check the fuses for compliance with rated current and prearcing time/current characteristic. • Perform functional test in accordance with Operating Instructions. • Check power control switch function: rotate switch in either direction and verify corresponding change in power output. • Check actual maximum output power against the specified maximum value at all outputs for all available operating modes, taking account of the nominal load resistances indicated in Section 8.1. • Check for correct acoustic and visual signals following HF current activation. • Carry out electrical checks in accordance with the test report sheet for periodic safety checks. Leakage currents may not exceed 1.5 times the value measured initially and at the same time not exceed the specified limit value either. The values measured first are available from the test report attached, which was established when the unit was first installed. We recommend the user to record all safety checks and related results in an equipment log. If the unit is not fully reliable and/or safe to operate, it must either be repaired or the user must be informed of the potential hazards involved in operating the system. Important note! The above checks may be carried out only by qualified Gebrüder Martin service personnel or by a service representative that has been specially authorized to carry out such work. 18 V 2.1 Instructions for Use Electrosurgical Unit KLS Martin ME MB1 with endo-mode 6 Accessories The unit may only be used in combination with accessories, parts subject to wear and disposables that have been evidenced as safe for use by way of a Declaration of Conformity. The use of untested accessories from other manufacturers may pose a hazard. In cases of doubt, please contact the manufacturer. For accessories specially certified for use with KLS Martin electrosurgical units, please refer to the KLS Martin Accessories Catalog, which is available from Gebrüder Martin or can be directly downloaded via www.klsmartin.com. 7 Care of the Unit Be sure to observe all national hygiene and preparation-for-reuse regulations. 7.1 Cleaning and Disinfecting Always disconnect the unit from the mains before cleaning and disinfecting it. When using cleaning agents and disinfectants, no liquid must be allowed to enter the unit, particularly when employing sprays. Never use scouring agents, disinfectants or solvents that might scratch the housing or damage the unit otherwise. When cleaning or disinfecting the unit’s outer surfaces, adhere to recommended in-house procedures or use a nationally recognized and approved method. Be sure that no liquids penetrate into the housing! Never sterilize the unit! Note that the unit may only be used after all disinfectant residues have been carefully removed! Manual disinfecting of accessories: When disinfecting accessories (either by surface disinfection or immersion), the user is required to observe the respective manufacturer’s instructions as regards compatibility with the material in question, dosage and exposure time. Important note • Accessories for electrosurgical equipment must always be kept in perfect working order. Malfunctioning, damaged or defective accessories can pose a danger to patient and operator alike and impair the proper functioning of the electrosurgical unit. Accessories unfit for use must be discarded.
