WARNINGS A. THIS DEVICE IS A “BF” TYPE DEVICE. TYPE “BF” EQUIPMENT IS A TYPE B EQUIPMENT WITH AN F TYPE APPLIED PART. Type B is a piece of equipment providing a particular degree of protection against electric shock, particularly regarding: -Allowable leakage current -Reliability of the protective earth connection. F-Type isolated applied part. Applied part isolated from all other parts of the equipment to such a degree that the patient leakage current allowable in single fault condition is not exceeded when a voltage equal to 1.1 times the highest rated mains voltage is applied between the applied part and earth. B. AVOIDING UNINTENTIONAL PATIENT BURNS 1) Do not activate electrode until all components are in place 2) Be certain to have an unobstructed path and view 3) Use only non-conductive ancillary instruments 4) Remove patient jewelry, metal drape clips, (etc.) and needles 5) A patient return electrode (pad) must be used. The entire area of the grounding pad should be reliability attached to the patient’s body and as close to the operating field as possible 6) Place footswitch in safe position, out of traffic 7) Turn console “OFF” or place in “WAIT” state when not in use 8) Do not use unit on small appendages due to current density. Bipolar techniques may be desirable for use on small appendages. C. THERMAL INJURY AND DEFECTS OF TISSUE TREATED WITH LOOP ELECTRODES Possible injury to cervical tissue may include: (1) thermal coagulation injury of the cervix, up to one-third the thickness of normal epithelium of the cervix, (2) fragmentation of squamous epithelium of the cervix attributable to long exposure periods along the excision site that allows heat to dissipate laterally, and (3) partial coagulation of the endocervical epithelium because of lateral radiation of heat. Loop electrosurgical excision procedures may also produce thermal defects at the periphery of the excised tissue and may make histopathologic interpretation difficult or impossible and may prevent accurate diagnosis and the evaluation of the need for further treatment. D. FLAMMABLE GASES / SOLUTIONS When using a flammable preparatory solution, such as alcohol, be certain that the solution has completely evaporated before using electrosurgery.

External anogenital lesion
Large vaginal intraepithelial neoplastic (VAIN) lesions
Cervical conization indications
CONTRAINDICATIONS FOR OB/GYN APPLICATIONS
The following are typical contraindications for performing the LEEP/LLETZ procedure. It is imperative that the physician carefully weigh the risks and benefits of treatment versus non-treatment in contraindicated patients: Pregnancy
Gross invasive carcinoma of the cervix
A bleeding disorder
Acute or active inflammation of the cervix, endometrium, fallopian tube, ovary or peritoneum (cervicitis, endometritis, tubo-ovarian inflammatory disease or pelvic inflammatory disease)

Less than 3 months postpartum
Equivocal cervical abnormality
ELECTROSURGICAL TISSUE EFFECT Delivery of continuous sinusoid waveform currents through a small electrode at appropriate power levels can cause rapid heating of the intracellular fluids in the cells in close proximity to the electrode, turning these fluids into steam. The significant increase in volume (approximately five times) causes cellular structure to rupture, creating the clinical effect of (CUT), with little or no hemostatic effort along the margin of the divided tissue. Delivery of short duration pulses of R/F currents through a small electrode at appropriate power levels can cause heating of intracellular fluids at a more gradual pace. This allows evaporation of these fluids without rupturing the cellular structure, creating the clinical effect of desiccation or (COAG) with the division of tissue. By varying the pulse to an intermediate duration, it is possible to get a clinical effect to combine, or “blend” the clinical characteristics of CUT and 37962 • Rev. A • 9/13
Wallach Surgical Devices 6
COAG, yielding the effect referred to as “blend”, where tissue is divided with a desirable amount of hemostasis along the margins of the divided tissue. The Quantum 2000 has output load characteristics that cause the electrosurgical effects to remain consistent throughout the procedure. However, under some circumstances, it may be necessary to readjust the power settings during the procedure. ATTENDANT RISKS OF HIGH FREQUENCY ELECTROSURGERY Electrosurgery produces sparks which can ignite flammable materials. This includes solvents, adhesives, gauze, cotton and also liquids and gases. Further risks include: Pooling of flammable agents under the patient, in body depressions, in body cavities. Oxygen-saturated gauze and cotton wool Accumulated oxygen gas: under covers, drapes or clothing Ignition of endogenous gases in or near body cavities or osses ELECTROSURGERY Electrosurgery is the use of energy created by a high frequency alternating current. The resistance of the tissue to the passage of this current creates heat internally in the tissue, as in diathermy. Monopolar electrosurgery involves the use of two electrodes (an active electrode and a patient return plate or dispersive electrode) of greatly different sizes. This results in greatly increased current density at the point of the smaller electrode. While the electrode itself remains cold, the highly concentrated high frequency energy creates molecular heat inside each cell. By the choice of electrodes and selection and adjustment of the current, the operator controls the effect of this energy on the tissues to achieve the desired results. CAUTION: WHEN IN THE MONOPOLAR MODE, KEEP THE VOLTAGE/ POWER AS LOW AS POSSIBLE TO ACHIEVE THE DESIRED END EFFECT (due to the potential for capacitive coupling and inadvertent burning at high voltages) With electronically generated electrosurgery current, it is necessary to convert the sixty-cycle alternating current available at the wall outlet to the high frequency current needed for electrosurgery. This conversion is accomplished by a high frequency generator. The high frequency waveforms are precisely controlled for the various modes of operation. The peak average and RMS values of the desired waveforms are generated in accordance with scientifically and empirically derived standards which are known to result in the desired effects. FUNDAMENTALS OF ELECTROSURGERY As with any instrumentation or equipment used in your practice, there are some fundamental principles that should be learned in order to use electrosurgery safely and effectively. These principles apply generally to all procedures where electrosurgery is used. Familiarize yourself with them. 37962 • Rev. A • 9/13
Wallach Surgical Devices 7
THE ACTIVE ELECTRODES Be sure the electrodes are securely seated and firmly held in the handpiece so that the entire electrode shank is covered. In general, straight wire electrodes are used for incisions and for removing fine tissue. Loops are used for removing heavier tissue, planing and contouring. Ball electrodes are used for coagulation. Keep the electrode clean while operating. Tissue shreds and debris on the electrode reduce the effectiveness of the current and, by impeding the passage of the electrode through the tissue, slows down the stroke. This creates unnecessarily heavy coagulation, which can cause sloughing, and delay healing. Inspect the electrodes for proper insulation. BIOVAC SMOKE EVACUATOR OPERATION AUTOMATIC MODE OPTION The Biovac Smoke Evacuator is set up to operate automatically from the Quantum 2000. This is accomplished by means of a special IR LED (Infra Red Light Emitting Diode) in the Integration Unit, which is mounted on the rear panel of the Quantum 2000. When the “R/F Output” is activated by the operator, the rear panel LED produces an output which is received by the interface module of the Biovac interface assembly. The motor will come “ON” and stay “ON” for five (5) seconds after the energized output is terminated. PURGE BUTTON The Biovac may also be tested or used without the Quantum 2000 output by pressing the “Purge button” on the front panel. The motor will stay on for five (5) seconds after the button is released. Most purge operations (removing excess smoke) take only a few seconds. SET UP AND OPERATION OF THE WALLACH QUANTUM 2000 PRACTICE In the following section, cutting and coagulating are described. First, practice methods are suggested, including how to adjust the settings for optimal cutting and coagulating. Then general techniques are described which should help determine and develop the best specific techniques. 1)
2) 3)
Place the console on a flat, stable surface near the Wallach Biovac Smoke Evacuator. Connect the AC power cord(s) accordingly. Plug the removable footswitch into the front panel, if foot control is desired. Set it up in a convenient, low traffic area. Place the ON-OFF switch to “OFF”, and plug the console into a grounded 115 VAC electrical receptacle. This is an important safety feature. Use only Wallach approved disposable accessories. See page 15 for further information.

Remove the disposable patient return electrode from its packaging and attach it to the patient in accordance with the instructions. Be sure to follow all instructions regarding the location of the pad ensuring that good contact is made with the patient. Attach the disposable patient return pad (the patient electrode) securely into the black receptacle on the front panel of the instrument. Insert the disposable active electrode (handpiece) into the black receptacle on the top right side of the Quantum 2000. Either the button-control operated handpiece or the footswitch-operated handpiece may be used. The footswitch-operated handpiece requires an adaptor to fit into the top receptacle. Insert the selected electrode (loop) into the active electrode handpiece. Place the ON-OFF switch to “ON”. A red indicator lamp on the console (R/F ON) will indicate that the “hold” mode has been initialized. After “self-check” the green “System Ready” LED illuminates. NOTE: If the system does not cycle to the “System Ready” status and a series of prolonged audible beeps are heard, turn the system off and check for faulty hand, foot, or panel switches. See TROUBLESHOOTING section (page 18, Section G) of this manual for additional information. Ensure patient is connected securely to the return electrode (split pad) before beginning. WARNING: POSITIVE CONTACT MUST BE COMPLETE BETWEEN THE PATIENT AND THE GROUNDING PAD. IF NOT, SEVERE BURNING OF TISSUE MAY RESULT. THE ENTIRE AREA OF THE GROUNDING PAD SHOULD BE RELIABILY ATTACHED TO THE PATIENT’S BODY AND AS CLOSE TO THE OPERATING FIELD AS POSSIBLE. The output is selected by the mode selector buttons. When a mode is selected, the intensity should be set by depressing the “Raise” or “Lower” button. If either cut (pure cut/blended cut) or the coagulation mode is selected and the footswitch is depressed, the output will be active. When the footswitch or handpiece is actuated, the “R/F ON” lamp will illuminate and the beeper will emit a pulsing tone.
10) The system is ready for use and the “System Ready” LED will illuminate (green). If the operator feels the output of power is not sufficient, the dispersive electrode (split pad) should be checked to see that good contact is made with the patient before increasing the power setting. 11) “CROSS CONTROL” The sequence of operation of the Quantum 2000 is nonpreferential, that is either the footswitch (pedal) or the handswitch will activate the output (providing all safety measures are met). The footswitch and the handswitch cannot be operated simultaneously. IMPORTANT: If using footswitch, the button on front panel must be used to control the “Output” mode. When the “Coag” mode is selected on the front panel, the “Cut” or “Blend” modes cannot be invoked by the handswitch (yellow button). The “Cut” mode, if desired, must be selected on the front panel and then invoked either by the handswitch or the footswitch operated pencil.

WARNING: Positive contact must be complete between the patient and the grounding pad. If a “Split Pad” is not securely affixed to the patient, the “Patient Pad Loose” indicator LED (Red) will indicate an improper return path. The “Patient Pad Loose” safety circuitry disables the output when an unsafe condition occurs in the return pad circuit. If a single (not split) return pad is not securely affixed to the patient, severe return electrode burning of tissue in the vicinity of the return pad may result. Poor connections or insufficient contact area can cause undesirable R/F burns. The entire area of the grounding pad should be reliability attached to the patient’s body and as close to the operating field as possible. However, it is not recommended that a single (not split) pad is used. Use only approved Wallach split return pads. 12) Cable Placement: High-frequency cables should be routed clear of other instruments and arranged for minimum length. Cables to surgical electrodes should be positioned to prevent contact with PATIENT or other leads. Temporarily unused active electrodes should be stored in a location isolated from PATIENT. R/F LEAKAGE The Quantum 2000 has a sensitive error detection mode that disables the output and indicates that an error condition exists by illuminating the front panel “R/F Leakage Error” LED (red). This LED will indicate that an undesirable path exists from the return (or active) electrode to “Ground”. In this context “Ground” means any undesirable path or place. If such a path exists the patient should be inspected for any contact with metallic paths to tables, chairs or other “Non Isolated” objects. The purpose of this feature is to prevent R/F current from flowing in undesirable places where it could either cause burns or damage to ancillary equipment. 13) PATIENT CONTACT Operator-to-patient contact by direct skin-to-skin contact could make an undesired leakage path. Avoid skin-to-skin contact by insertion of dry gauze as necessary. Electrically insulating gloves should be worn by the operator. Unless absolutely necessary, the patient should not be touched when R/F power is activated. Patient should not come into contact with grounded metal parts or parts with a higher capacitance to ground (i.e. operating table supports, etc.). Use of antistatic sheeting is recommended for this purpose. THE POWER SETTING The operating mode (cut, blended cut, coagulate or wait) is selected by the mode selector buttons. When a mode is selected, the intensity should be set by depressing the POWER “Raise” or “Lower” buttons that control the digital display. When a mode is selected, the corresponding LED illuminates in the corner of each button to verify which mode is engaged.

When the footswitch is depressed, or the handpiece buttons are pressed, the “R/F ON” will illuminate (yellow). If either the “Cut” (pure or blend) or “Coagulation” mode is selected and the footswitch is depressed, the output will be active. In the “Wait” mode there will be no output. The piezo electric “Beeper” will indicate with an intermittent tone when the R/F Power is present at the output. Once contact is made with the electrode to the tissue, and a small current is flowing, the tone will become steady. The ideal power setting is the minimum settings where cutting and coagulating meet the criteria described on pages 13 and 14. If the power is too high, the tissue will be discolored and there will be considerable sparking when the electrode contacts the surface. If the power is too low, the electrode will drag through the tissue, tearing and burning, instead of cutting cleanly, and will pick up shredded and torn tissue. Power requirements will vary with the type and size of the electrode, the area of electrode surface in contact with the tissue, the nature of the tissue, whether cutting or coagulating, and the depth of the incision desired. Larger electrodes, deeper incisions, and tough fibrotic tissue are some indications for higher power settings. CAUTION: Do not use fine needle electrodes at high settings as they may be severely damaged by such use. When practicing with these electrodes, work up gradually from a low setting. Generally, you should not exceed a setting of 40 with fine needle electrodes. CAUTION: Do not use monitoring needle electrodes during electrosurgery. If monitoring electrode cables are used, the monitoring electrode cables should be placed as far away from electrosurgical cables AS POSSIBLE. If it is absolutely necessary to cross over any monitoring cable or patient-connected tubes such as I/V lines, etc., the crossing should be at right angles. Use of monitoring systems incorporating high frequency current limiting devices is recommended. CUTTING TECHNIQUES When cutting, always activate the electrode by stepping on the footswitch or pressing the yellow button on the handpiece before contacting the tissue. Plan the stroke. Before activating the electrode, take one or two practice strokes to be sure you can complete the planned stroke comfortably and correctly. At this time you can evaluate the size and shape of the electrode and the speed and depth of the stroke. When the practice stroke is comfortable, step on the footswitch, or press the yellow button on the handpiece, and make the planned cut.
37962 • Rev. A • 9/13

Use a smooth brushing motion without pressure. The electrode should pass through the tissue, without dragging, at a deliberate but not slow speed. Keep the electrode moving. Prolonged contact with any one part of the tissue can create excessive coagulation. CUTTING Blend: Cutting is done, not by the electrode, but by the high frequency energy concentrated at the electrode. This high frequency energy generates molecular heat in each cell to the point where the fluids in the cell vaporize and the cell explodes. By applying this energy to individual cells in sequence, that is, by moving the electrode continuously through the tissue, the line of destruction is limited and the cutting effect is realized. At the same time the capillaries are sealed, resulting in almost bloodless cutting, hence the term “blended cut”. (This is the preferred cutting for OB/GYN procedures.) Pure-Cut: This is almost like using a cold scalpel with very little or no hemostasis. CRITERIA OF GOOD CUTTING TECHNIQUE There are three criteria of good cutting technique: 1) The electrode should “float” through the tissue without dragging or resistance. 2) There should be only very slight, if any, change in the tissue color due to dehydration or charring. 3) No tissue shreds should adhere to the electrode. COAGULATING The Quantum 2000 is specially designed for high fulguration so tissue bleeders can be sealed without burning the uninvolved tissue. Coagulation takes place when the high frequency current is applied to the tissue with a current density sufficiently concentrated to dehydrate the cells and coagulate their organic contents, but without penetrating deeply into the tissue. This procedure is almost self-limiting, since the surface coagulation first created protects the underlying tissue against excessive depth of coagulation. Coagulation appears as a white spot on the surface of the tissue, emanating from the point of contact to the ball electrode. It is easy to determine the depth of coagulation since the depth is approximately equal to the lateral spread of coagulation. In contrast to cutting, when coagulating the ball electrode should contact the tissue before depressing the footswitch or handswitch. Start with a LOW power setting (15), setting mode button to “COAGULATION”.
37962 • Rev. A • 9/13
Wallach Surgical Devices 12
Contact the surface of the tissue lightly with the ball electrode. Depress the footswitch or handswitch to activate the current, coagulating the area for several seconds. Then release the footswitch or handswitch and remove the electrode from the tissue. Notice the appearance of the tissue. It should appear blanched. Turn the power intensity up step by step, repeating the procedure. Observe the characteristics of the coagulated tissue with each setting. The degree of coagulation obtained at a particular setting will vary with different tissue and different conditions. Determine which setting is best for various procedures. When treating any condition, if proper coagulation is not apparent after one application, immediately increase the intensity setting if the return pad is properly in place. CAUTION: Never repeatedly apply the current to the same area; this may create heat and seriously damage underlying tissues. COAGULATING TECHNIQUE The ball electrode is extremely useful when you are controlling hemorrhage. When applied for a second or two, electronic coagulation current will coagulate small capillaries easily. Larger vessels can be picked up with hemostats which in turn may be touched by the ball electrode, using electronically generated current. This will seal all vessels which are held in the tips of the forceps. NOTE: Always contact the tissue before depressing footswitch or handswitch when using the coagulation current. TECHNIQUE GUIDANCE FOR OB/GYN PROCEDURES A.
The endocervix may not be included in the loop excision, and the results of endocervical curettage (ECC) may not be predictive of either residual or invasive disease after loop excision procedures. If the ECC is positive for dysplasia, a standard cone biopsy should be considered.
B.
Loop excision procedures performed with small diameter wire loop electrodes produce multiple small pieces of cervical tissue and may provide a less acceptable tissue specimen for histopathologic analysis.
C.
Larger lesions involving multiple quadrants of the cervix are more difficult to remove with loop electrodes.
37962 • Rev. A • 9/13
Wallach Surgical Devices 13
SEVERED VESSELS Clamp the bleeder with a hemostat. Using electronically generated current, touch a ball electrode to any part of the hemostat. Depress the footswitch pedal to activate the current for several seconds. Then release the pedal and remove the electrode. Be sure the current is set as high as is necessary to achieve coagulation. After the application of coagulating current, remove the hemostat. Bleeding should have stopped; if not, repeat the procedure. Suture ligation may be required if R/F is unsuccessful. When using electronically generated current, it is safe to hold the hemostat in a gloved hand while holding the electrode handle in the other during this procedure. ANESTHESIA Adequate anesthesia is indicated for all electrosurgical procedures. It is usually advisable to anesthetize tissue adjacent to the intended operative site, in the event it becomes necessary to extend the operative area. BIOPSY The use of electrosurgery for cervical biopsy has advantages that electrosurgery seals the capillaries and lymphatics as it cuts. The specimen should, whenever possible, include two to three millimeters of attached normal tissue. Small (up to one half inch) masses should be removed in one piece. Using cutting current at a relatively high setting and a needle electrode, incise all around the mass in an elliptical pattern, including two to three millimeters of attached normal tissue. Small masses may also be removed by using a suitable loop electrode, large enough so that it can excise the mass itself as well as two to three millimeters of attached normal tissue at the same time. Specimens from larger masses should be taken in the form of pie-shaped wedges. Using a needle electrode and cutting current, start at the apex of the wedge at the center of the suspicious mass. The base of the wedge should include two to three millimeters of attached normal tissue.

THE WALLACH RETURN ELECTRODE A return dispersive electrode must be used to operate the Quantum 2000 system. The return electrode should be of the “split or dual” type to take best advantage of the safety features for preventing R/F burns due to poor adhesion. NOTE: For optimum patient safety with the use of the Quantum 2000 system, it is strongly recommended to use only authorized and genuine Wallach split/dual dispersive return electrode pads (Part Number 909078). No other return electrode pad has been tested or verified to the level of safety and performance of an authorized and genuine Wallach Quantum 2000 split/dual dispersive electrode pad. WARNING: A one-piece return pad is not recommended since the one-piece pad is not continuously monitored for the integrity of the electrical connection established at the area of contact. Patient injury may result. MAINTENANCE After each use, the unit must be cleaned and disinfected. To sanitize unit, wipe down with a disinfectant. While the finish on the instrument cabinet will resist scuffing and the chemical attack of most acids and alkalies, any liquids spilled on the cabinet should be wiped up immediately. ACCESSORIES NOTE: Use only genuine Wallach Quantum 2000 accessories (dispersive pads, hand switch pencils, footswitch operated pencils, and electrodes) for optimal system performance and patient safety. The use of non-Wallach authorized and genuine accessories is not recommended nor have been tested and verified to the level of safety and performance of a genuine Wallach accessory. Contact Wallach or your Wallach distributor for a list of current genuine Quantum 2000 accessories. DISPOSABLE HANDSWITCH PENCILS All Wallach disposable handswitch pencils are sold sterile and are for single patient use only. For the Wallach Quantum 2000, use only Wallach genuine Disposable Handswitch Pencils (activated accessory with finger switch) which comply with IEC 60601-2-2: 4th edition. Genuine Wallach Disposable Footswitch Operated Pencils and electrodes are available, sold sterile and are for single patient use only. If you have any questions or require specific accessories, contact your Wallach Representative or local distributor. A variety of genuine Wallach disposable electrodes and accessories are available. Use only cables approved by Wallach. Regular inspection is required for accessories, including your electrode cables for damage to the insulation.
