KEY FEATURES
The Aaron 3250 includes the latest technology. This unit offers unsurpassed performance, flexibility, reliability, and convenience.
It includes the following features:
•Two Cut Modes, Cut I & Cut II
Two cut modes give the surgeon flexibility to cut all types of tissue without losing performance.
Cut I generates constant output power over a wide range of impedances. Refer to Figure A-1 in the Technical
Specifications section of this guide.
Cut II is a softer cut that generates constant output power over a small range of impedances. Refer to Figure A-2 in the Technical Specifications section of this guide.
• Blend with 10 Settings
The Blend mode is a combination of cutting and hemostasis. The 3250 gives the surgeon freedom to adjust the desired level of hemostasis. A setting of 1 is minimal blend with maximum cutting effect. A setting of 10 is maximum hemostasis (blend) with minimal cutting effect. This adjustment is easily achieved by an incremental adjustment. Refer to Section 2, Controls, Indicators, and Receptacles, Cut and Blend Controls. The Blend mode improves the rate of targeted tissue desiccation without increasing the power delivered by the generator.
• Presets
The surgeon can store 10 user-defined presets for easy recall of frequently used settings.
• Two levels of coagulation: Coagulation and Fulguration
Coagulation provides precise control of bleeding in localized areas.
Fulguration provides greater control of bleeding in highly vascular tissue over broad surface areas.
• Return electrode sensing and contact quality monitoring
The 3250 incorporates a return electrode contact quality monitoring system (Bovie NEM™). This system detects the type of return electrode: solid or split. The system also continually monitors the contact quality between the patient and the split return electrode. This feature is designed to minimize patient burns at the return electrode site.
• FDFS™ (Fast Digital Feedback System)
The FDFS™ (Fast Digital Feedback System) measures voltage and current at 5,000 times a second and immediately adjusts the power to varying impedance during the electrosurgical procedure. The unit’s digital technology senses and responds to changes in tissue and density. Unlike analog, this feature reduces the need to adjust power settings manually.
NOTICE:
The Bovie NEM™ system recommends that you use a split return electrode.
Before activation, pad placement and visual verification of the split return electrode (split pad) indicator on the front panel is recommended. After connecting the split pad to the generator and placing the split pad securely to the patient, give the unit 5 to 10 seconds to recognize the split pad. The split pad indicator will illuminate green. If the split pad and cord are attached to the generator without secure contact to the patient, the alarm indicator will illuminate red.
• Memory
The unit automatically powers up to the last selected preset settings.
• Isolated RF output
This minimizes the potential of alternate site burns.

SAFETY
The safe and effective use of electrosurgery depends to a large degree on factors solely under the control of the operator. There is no substitute for a properly trained and vigilant medical staff. It is important that they read, understand, and follow the operating instructions supplied with this electrosurgical equipment.
Physicians have used electrosurgical equipment safely in numerous procedures. Before starting any surgical procedure, the surgeon should be familiar with the medical literature, complications, and hazards of using electrosurgery in that procedure.
To promote the safe use of the Aaron 3250, this section presents the warnings and cautions that appear throughout this user’s guide. It is important that you read, understand, and follow the instructions in these warnings and cautions so that you can operate this equipment with maximum safety. It is also important that you read, understand, and follow the instructions for use in this user’s guide.
WARNINGS:
Hazardous Electrical Output - This equipment is for use only by trained, licensed physicians.
Danger: Fire / Explosion Hazard - Do not use the Aaron 3250 in the presence of flammable materials.
Fire / Explosion Hazard - The following substances will contribute to increased fire and explosion hazards in the operating room:
• Flammable substances (such as alcohol based skin prepping agents and tinctures)
• Naturally occurring flammable gases which may accumulate in body cavities such as the bowel
• Oxygen enriched atmospheres
• Oxidizing agents (such as nitrous oxide [N
2
0] atmospheres).
The sparking and heating associated with electrosurgery can provide an ignition source.
Observe fire precautions at all times. When using electrosurgery in the same room with any of these substances or gases, prevent their accumulation or pooling under surgical drapes, or within the area where electrosurgery is performed.
Connect the power cord to a properly polarized and grounded power source with the frequency and voltage characteristics that match those listed on the back of the unit.
Electric Shock Hazard - Connect the generator power cord to a properly grounded receptacle.
Do not use power plug adapters.
Electric Shock Hazard - Always turn off and unplug the generator before cleaning.
Fire Hazard - Do not use extension cords.
Patient Safety - Use the generator only if the self-test has been completed as described.
Otherwise, inaccurate power outputs may result.
Failure of the high frequency electrosurgical equipment could result in an unintended increase of output power.
The instrument receptacles on this generator are designed to accept only one instrument at a time. Do not attempt to connect more than one instrument at a time into a given receptacle. Doing so will cause simultaneous activation of the instruments.
Use the lowest output setting necessary to achieve the desired surgical effect. Use the active electrode only for the minimum time necessary in order to lessen the possibility of unintended burn injury. Pediatric applications and/or procedures performed on small anatomic structures may require reduced power settings. The higher the current flow, and the longer the current is applied, the greater the possibility of unintended thermal damage to tissue, especially during use on small structures.
1-4 Bovie Medical Corporation
WARNINGS:
Use electrosurgery with caution in the presence of internal or external devices such as pacemakers or pulse generators. Interference produced by the use of electrosurgical devices can cause devices such as pacemakers to enter an asynchronous mode or can block the pacemaker effect entirely. Consult the device manufacturer or hospital Cardiology Department for further information when use of electrosurgical appliances is planned for patients with cardiac pacemakers or other implantable devices.
If the patient has an Implantable Cardioverter Defibrillator (ICD), contact the ICD manufacturer for instructions before performing an electrosurgical procedure. Electrosurgery may cause multiple activation of ICDs.
Do not use electrosurgical equipment unless properly trained to use it in the specific procedure being undertaken. Use by physicians without such training has resulted in serious, unintended patient injury, including bowel perforation and unintended, irreversible tissue necrosis.
For surgical procedures where the high frequency 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.
In some circumstances, potential exists for alternate site burns at points of skin contact (e.g., between the arm and the side of the body). This occurs when electrosurgical current seeks a path to the return electrode that includes the skin-to-skin contact point. Current passing through small skin-to-skin contact points is concentrated and may cause a burn. This is true for grounded, ground referenced, and isolated output generators.
To reduce the potential for alternate site burns, do one or more of the following:
• Avoid skin-to-skin contact points, such as fingers touching leg, when positioning the patient.
• Place 5 to 8 cm (2 to 3 in.) of dry gauze between contact points to ensure that contact does not occur.
• Position the return electrode to provide a direct current route between the surgical site and the return electrode which avoids skin-to-skin contact areas.
• In addition, place patient return electrodes according to the manufacturer’s instructions.
Potential for alternate site burns increases if the return electrode is compromised. Bovie Medical recommends the use of split return electrodes and Bovie generators with a contact quality monitoring system.
Do not wrap the accessory cords or return electrode cords around metal objects. This may induce currents that could lead to shocks, fires, or injury to the patient or surgical team.

CAUTIONS:
At no time should you touch the active electrode or bipolar forceps. A burn could result.
Do not stack equipment on top of the generator or place the generator on top of electrical equipment. These configurations are unstable and/or do not allow adequate cooling.
Provide as much distance as possible between the electrosurgical generator and other electronic equipment (such as monitors). An activated electrosurgical generator may cause interference with them.
Non-function of the generator may cause interruption of surgery. A backup generator should be available for use.
Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical team when an accessory is active.
When using a smoke evacuator in conjunction with the electrosurgical generator, place the smoke evacuator a distance from the generator and set the generator volume control at a level that ensures that the activation tones can be heard.
The use of high frequency current can interfere with the function of other electromagnetic equipment.
When high frequency surgical equipment and physiological monitoring equipment are used simultaneously on the same patient, place any monitoring electrodes as far as possible from the surgical electrodes. Monitoring systems incorporating high frequency current-limiting devices are recommended.
Do not use needles as monitoring electrodes during electrosurgical procedures. Inadvertent electrosurgical burns may result.
To avoid the possibility of an electrosurgical burn to either the patient or the physicians, do not allow the patient to come in contact with a grounded metal object during activation. When activating the unit, do not allow direct skin contact between the patient and the physician.
To avoid the possibility of a burn to the patient, when using a split pad do not activate the unit if the solid pad indicator is illuminated green or the red alarm indicator remains illuminated red. This could indicate improper pad placement or a faulty NEM circuit.
Remove any loose fitting jewelry from the patient before activation.
Examine all accessories and connections to the electrosurgical generator before use. Ensure that the accessories function as intended. Improper connection may result in arcs, sparks, accessory malfunction, or unintended surgical effects.
When not using active accessories, place them in a holster or in a clean, dry, non-conductive, and highly visible area not in contact with the patient. Inadvertent contact with the patient may result in burns.
Studies have shown that smoke generated during electrosurgical procedures can be potentially harmful to patients and the surgical team. These studies recommend adequately ventilating the smoke by using a surgical smoke evacuator or other means.

Connect the power cord to a properly polarized and grounded power source with the frequency and voltage characteristics that match those listed on the back of the unit.
Fire Hazard - Do not use extension cords.
Patient Safety - Use the generator only if the self-test has been completed as described.
Otherwise, inaccurate power outputs may result.
The instrument receptacles on this generator are designed to accept only one instrument at a time. Do not attempt to connect more than one instrument at a time into a given receptacle. Doing so will cause simultaneous activation of the instruments.
Failure of the high frequency electrosurgical equipment could result in an unintended increase of output power.
Do not use electrosurgical equipment unless properly trained to use it in the specific procedure being undertaken. Use by physicians without such training has resulted in serious, unintended patient injury, including bowel perforation and unintended, irreversible tissue necrosis.
For surgical procedures where the high frequency 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.
If the patient has an implantable cardioverter defibrillator (ICD), contact the ICD manufacturer for instructions before performing an electrosurgical procedure. Electrosurgery may cause multiple activation of ICDs.
In some circumstances, potential exists for alternate site burns at points of skin contact (e.g., between the arm and the side of the body). This occurs when electrosurgical current seeks a path to the patient return electrode that includes the skin-to-skin contact point. Current passing through small skin-to-skin contact points is concentrated and may cause a burn. This is true for grounded, ground referenced, and isolated output generators.
To reduce the potential for alternate site burns, do one or more of the following:
• Avoid skin-to-skin contact points, such as fingers touching leg, when positioning the patient.
• Place 5 to 8 cm (2 to 3 in.) of dry gauze between contact points to ensure that contact does not occur.
• Position the return electrode to provide a direct current route between the surgical site and the return electrode which avoids skin-to-skin contact areas.
• In addition, place return electrodes according to the manufacturer’s instructions.
Potential for alternate site burns increases if the return electrode is compromised. Bovie Medical recommends the use of split return electrodes and Aaron generators with a contact quality monitoring system.

CAUTIONS:
Do not stack equipment on top of the generator or place the generator on top of electrical equipment. These configurations are unstable and/or do not allow adequate cooling.
Provide as much distance as possible between the electrosurgical generator and other electronic equipment (such as monitors). An activated electrosurgical generator may cause interference with them.
Non-function of the generator may cause interruption of surgery. A backup generator should be available for use.
Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical team when an accessory is active.
When using a smoke evacuator in conjunction with the electrosurgical generator, place the smoke evacuator a distance from the generator and set the generator volume control at a level that ensures that the activation tones can be heard.
NOTICE:
If required by local codes, connect the generator to the hospital equalization connector with an equipotential cable.
SETTING UP
1. Verify that the generator is Off by pressing the power switch Off (O).
2. Place the generator on a stable flat surface, such as a table, platform, or medical cart. Carts with conductive wheels are recommended. For details, refer to the procedures for your institution or to local codes. Provide at least 10 to
15 cm (4 to 6 in.) of space from the sides and top of the generator for cooling. Normally, the top, sides, and rear panel are warm when you use the generator continuously for extended periods of time.
3. Plug the generator power cord into the AC Power Cable Receptacle on the rear panel.
4. Plug the generator power cord into a grounded receptacle.
5. Turn on the generator by pressing the power switch On (|). Verify the following:
• All visual indicators and displays on the front panel illuminate.
• Activation tones sound to verify that the speaker is working properly.
6. If the self-test is successful, a tone sounds. Verify the following:
• A Cut mode is selected; a Coag mode is selected.
• Each display shows a power setting. The unit automatically powers up to the last selected setting.
• The Patient Return Electrode Alarm Indicator illuminates red.
If the self-test is not successful, an alarm tone sounds. An error code will appear in the Bipolar display, in most cases, the generator is disabled. Note the error code and refer to Section 6, Troubleshooting.
Once the self-test is successful, connect the accessories and set the generator controls. Refer to Preparing for
Monopolar Surgery or Preparing for Bipolar Surgery later in this section.
User’s Guide • Aaron 3250™ 4-3
PREPARING FOR MONOPOLAR SURGERY
Monopolar surgery requires a return electrode.
Applying the Return Electrode
To maximize patient safety, Bovie Medical recommends using a split return electrode and a Aaron generator with a contact quality monitoring system (Bovie NEM™).
NOTICE:
The Bovie NEM™ system recommends that you use a split return electrode.
Before activation, pad placement and visual verification of the split return electrode (split pad) indicator on the front panel is recommended. After connecting the split pad to the generator and placing the split pad securely to the patient, give the unit 5 to 10 seconds to recognize the split pad. The split pad indicator will illuminate green. If the split pad and cord are attached to the generator without secure contact to the patient, the alarm indicator will illuminate red.
Refer to the manufacturer’s instructions for application site and placement procedures. When using metal plate return electrodes, use a conductive gel specifically designed for electrosurgery. Select a return electrode site with good blood flow. While a properly applied electrode results in minimal tissue heating beneath the electrode, a good blood flow helps carry heat away from the site.
1. Connect the cable to the Return Electrode receptacle on the front of the unit.
The unit will automatically sense the presence of a split or solid return electrode and, if a split return electrode is used, will constantly monitor the resistance at the contact between the electrode and the patient.
2. Adjust the Blend setting to the desired amount of hemostasis (Level 1 - 10). Adjustment is preformed by pressing the up or down buttons next to the Blend setting indicator.
Select the desired power settings for Cutting. Adjustment is preformed by pressing the up or down buttons next to the Cut display.
Select the mode of operation for Coagulation, either Coagulation or Fulguration.
Select the desired power setting for Coagulation. Adjustment is preformed by pressing the up or down buttons next to the Coag display.

ACTIVATION SAFETY
WARNINGS:
Do not wrap the accessory cords or patient return electrode cords around metal objects. This may induce currents that could lead to shocks, fires, or injury to the patient or surgical team.
Danger: Fire / Explosion Hazard - Do not use the Aaron 3250 in the presence of flammable anesthetics.
Fire / Explosion Hazard - The following substances will contribute to increased fire and explosion hazards in the operating room:
• Flammable substances (such as alcohol based skin prepping agents and tinctures)
• Naturally occurring flammable gases that may accumulate in body cavities such as the bowel
• Oxygen enriched atmospheres
• Oxidizing agents (such as nitrous oxide [N
2
O] atmospheres).
The sparking and heating associated with electrosurgery can provide an ignition source. Observe fire precautions at all times. When using electrosurgery in the same room with any of these substances or gases, prevent their accumulation or pooling under surgical drapes, or within the area where electrosurgery is performed.
Use the lowest output setting necessary to achieve the desired surgical effect. Use the active electrode only for the minimum time necessary in order to lessen the possibility of unintended burn injury. Pediatric applications and/or procedures performed on small anatomic structures may require reduced power settings. The higher the current flow, and the longer the current is applied, the greater the possibility of unintended thermal damage to tissue, especially during use on small structures.
Use electrosurgery with caution in the presence of internal or external devices such as pacemakers or pulse generators. Interference produced by the use of electrosurgical devices can cause devices such as pacemakers to enter an asynchronous mode or can block the pacemaker effect entirely. Consult the device manufacturer or hospital Cardiology Department for further information when use of electrosurgical appliances is planned for patients with cardiac pacemakers or other implantable devices.
4-8
CAUTIONS:
The use of high frequency current can interfere with the function of other electromagnetic equipment.
When high frequency surgical equipment and physiological monitoring equipment are used simultaneously on the same patient, place any monitoring electrodes as far as possible from the surgical electrodes.
Do not use needles as monitoring electrodes during electrosurgical procedures. Inadvertent electrosurgical burns may result.
To avoid the possibility of an electrosurgical burn to either the patient or the physicians, do not allow the patient to come in contact with a grounded metal object during activation. When activating the unit, do not allow direct skin contact between the patient and the physician.
To avoid the possibility of a burn to the patient, when using a split pad do not activate the unit if the solid pad indicator is illuminated green or the red alarm indicator remains illuminated red. This could indicate improper pad placement or a faulty NEM circuit.
Remove any jewelry from the patient before activation.
Studies have shown that smoke generated during electrosurgical procedures can be potentially harmful to patients and the surgical team. These studies recommend adequately ventilating the smoke by using a surgical smoke evacuator or other means.
1
Examine all accessories and connections to the electrosurgical generator before use. Ensure that the accessories function as intended. Improper connection may result in arcs, sparks, accessory malfunction, or unintended surgical effects.
When not using active accessories, place them in a holster or in a clean, dry, non-conductive, and highly visible area not in contact with the patient. Inadvertent contact with the patient may result in burns.
