Model 800-EU and 900 Users Guide

INTRODUCTION Thank you for purchasing the Aaron High Frequency Desiccator. Please visually check the unit to ensure that damage did not occur during shipment and that all standard items are included. The basic unit should include the electrosurgical unit with power cord, a handpiece, 50 disposable sharp dermal tips (A900 only), 50 disposable blunt dermal tips (A900 only), and a mounting kit (A837). If there are any discrepancies, please contact Aaron at +1-727-384-2323. EU Authorized Representative: Peter J. Smith Medical Products Marketing 18 Yeates Close Thame 0X9 3AR, UK

PRECAUTIONS In order to safely operate the Aaron High Frequency Desiccator, several precautions need to be followed. CAUTIONS: Federal (USA) law restricts sale of this device to or on the order of a physician. Use caution when using the Aaron High Frequency Desiccator on patients who have a pacemaker or metal implant. The function of other electromagnetic equipment can be interfered with by the use of high frequency current. When high frequency surgical equipment and physiological monitoring equipment are used simultaneously on the same patient, any monitoring electrodes should be placed as far as possible from the surgical electrodes. Needle monitoring electrodes are not recommended. To avoid the possibility of an electrosurgical burn to either the patient or the physician, do not allow the patient to come in contact with a grounded metal object during activation. When activating the unit, there should be no direct skin contact between the patient and the doctor. It is also advisable to remove any loose fitting jewelry from the patient prior to activation. Cables should be positioned in such a way that contact with the patient or other leads is avoided. Temporarily unused active electrodes should be stored isolated from the patient. This is a non-sterile product. System is not Mains Voltage Regulated. Recalibration is required if input Mains Voltage is changed. To reduce the risk of electrical shock, do not remove back plate. Refer servicing to qualified personnel.

WARNINGS: Do not use the Aaron High Frequency Desiccator in the presence of flammable anesthetics. Fire could result. Keep the power setting as low as possible to achieve the desired effect. For surgical procedures where the HF current could flow through parts of the body having a relatively small cross-sectional area, the use of bipolar techniques may be desirable to avoid unwanted coagulation. Apparent low output or failure of the surgical equipment to function correctly at the normal operating settings may indicate faulty application of the neutral electrode or poor contact in its connections. Store the unit in a cool, dry place. Grounding reliability can only be achieved when the equipment is connected to an equivalent receptacle marked “Hospital Only” or “Hospital Grade”.

UNIT OPERATION The Aaron High Frequency Desiccator produces radio frequency current which is useful for the removal and destruction of superficial cutaneous and mucosal lesions. This is done by performing desiccation and fulguration procedures. Electrosurgical desiccation occurs when the electrode is placed directly onto the surface of the lesion. Fulguration occurs when the electrode is held slightly above the lesion and an arc is delivered to the lesion. The unit also provides fast and efficient bleeding control by coagulation of capillaries and small blood vessels. For the majority of desiccation, fulguration, and coagulation procedures utilizing the standard handpiece in the monopolar output, the patient plate is optional. When used, the patient plate will intensify the coagulation properties of the unit and also lessen the opportunity for an electrosurgical burn. The optional footswitch adds versatility when using the standard handpiece in the monopolar output, as the footswitch allows you to activate the unit by either the handpiece or the footswitch. Bipolar outputs are available for those physicians who prefer to utilize bipolar forceps to perform coagulation procedures. A footswitch is required when using the bipolar output and the patient plate is not used. Procedures that are performed in sensitive areas may require an anesthetic. Flammable anesthetics should not be used. If you are unfamiliar with the operation of a low powered electrosurgery unit, it is advisable to practice on chicken or lean flank steak to visualize the effects at various output and power levels.

SETUP PROCEDURES 1. Mount the Aaron High Frequency Desiccator on the wall or optional mobile stand using the standard mounting kit (see figure 1). Do not operate the unit in the horizontal position, as liquids may spill into unit.

Figure 2 2. Plug the female end of the power cord into the base of the unit (see figure 2, letter A). 3. Plug the male end of the power cord into a grounded wall receptacle. 4. Plug the handpiece into the monopolar output on the lower left of the front on the unit (see figure 2, letter B). The plug is designed to fit in only one direction. Plug the smaller round connector from the handpiece (A900 only) into the receptacle on the bottom of the unit (see figure 2, letter B). The three button handpiece is designed to give the doctor complete fingertip control of the power output settings. 5. Slide the standard electrode into the handpiece until it is firmly seated (see figure 2, letter C). The handpiece will accept most standard 3/32" electrodes. 6. Slide the handpiece from above into the holder on the right side of the unit. 7. Turn the unit power on utilizing the switch on the right side panel of the unit (see figure 2, letter D). 8. Set the power output either by using the dial on the front of the unit (see figure 2, letter E) or on Aaron 900 unit only by the up and down buttons on the handpiece (see figure 2, letter J). When power level adjustment is being made by the handpiece an audible tone will sound to indicate that the power level has been changed. Depressing and holding the up or down buttons will cause the power settings to change more rapidly for quick adjustment of the output settings. Power output is displayed in “.1” watt increments below 10 watts and in whole numbers from 10 to 30 watts. NOTICE: The output settings can not be adjusted when the unit is being activated.

9. To activate the unit, remove the handpiece from the holder. Place the handpiece in the desired position and depress the activation button (see figure 2, letter K). When the unit is activated, an audible tone is sounded and the blue active light will illuminate (see figure 2, letter F). 10. To use the optional grounding plate with cord (A802EU), insert the plug of the cord into the grounding plate output (see figure 2, letter G) and connect the other end into the grounding plate. The plate should be placed underneath the patient at a point where the entire plate is covered by bare skin. Do not use gels or creams on the plate. 11. To use the optional bipolar cord (A827EU), insert the plugs into the bipolar outputs (see figure 2, letter H). The cord is then plugged into the forceps. A sliding gate behind the monopolar and bipolar outputs prevents the user from using both simultaneously. 12. The optional footswitch is plugged into the footswitch output and placed on the floor (see figure 2, letter I). The footswitch can be used with monopolar procedures and must be used with bipolar procedures. 13. When the procedure is completed, turn the unit off utilizing the switch on the right side panel of the unit. 14. Return the handpiece to the holder on the right side of the unit and remove the electrode. The electrode should be disposed of after each procedure. If contamination has occurred to the handpiece, the handpiece should also be sterilized. 15. Adjustment of the audible tone is achieved by a switch located on the rear of the unit (see figure 3). Two tone choices are available, high and low. A small screwdriver will be necessary to make the adjustment. Figure 3

MAINTENANCE The Aaron High Frequency Desiccator requires periodic cleaning. When the unit case requires cleaning, simply utilize a soap and water solution and wipe clean. Be careful to not have any water enter into the unit through the various openings. Dry the unit with a clean, lint-free cloth.

STERILIZATION The Aaron High Frequency Desiccator and standard accessories are supplied non-sterile. The handpiece may be cleaned and sterilized. Refer to the instruction sheet that accompanies the electrode and handpiece for specific instructions on cleaning and sterilization. We recommend that all contaminated electrodes and handpieces be sterilized prior to disposal.
