KEY FEATURES The Aaron 1250 Electrosurgical Generator includes the latest technology. This unit offers unsurpassed performance, flexibility, reliability, and convenience. It includes the following features: • Two levels of coagulation: Pinpoint Coagulation and Fulguration Pinpoint 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 Aaron 1250 incorporates a return electrode contact quality monitoring system (Bovie NEM™). This system determines the type of patient return electrode: single or split plate. The system also continually monitors the contact quality between the patient and the split-plate return electrode. This feature is designed to eliminate patient burns at the return electrode site. NOTICE The Bovie NEM™ system recommends that you use a split-plate patient return electrode.

• Memory The unit automatically powers up to the last used modes and power settings. • Isolated RF output This minimizes the potential of alternate site burns. • Standard connectors These connectors accept the latest monopolar and bipolar instruments. • Self diagnostics These diagnostics continually monitor the unit to ensure proper performance.

COMPONENTS AND ACCESSORIES You should receive the following components with your generator: • Aaron 1250 Electrosurgical Generator • Three electrodes • Hospital-grade power cord • One reusable grounding cord • User’s Guide • Five disposable split grounding pads • Two disposable pencils (one standard push button, one smoke & fluid evacuation)

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 1250 Electrosurgical Generator, this section presents the warnings and cautions that appear throughout this user’s guide. So that you can operate this equipment with maximum safety, it is important that you read, understand, and follow the instructions in these warnings and cautions.

WARNINGS Hazardous Electrical Output - This equipment is for use only by trained, licensed physicians. Danger: Fire / Explosion Hazard - Do not use the Aaron 1250 electrosurgical generator 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 which may accumulate in body cavities such as the bowel • Oxygen enriched atmospheres • Oxidizing agents (such as nitrous oxide [N20] 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. Use electrosurgery with caution in the presence of internal or external pacemakers. Interference produced by the use of electrosurgical devices can cause devices such as a pacemaker to enter an asynchronous mode or can block the pacemaker effect entirely. Consult the pacemaker manufacturer or hospital Cardiology Department for further information when use of electrosurgical appliances is planned for patients with cardiac pacemakers. 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 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.

WARNINGS 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 patient 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. Aaron Medical recommends the use of split patient return electrodes and Aaron Medical generators with a contact quality monitoring system. 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.

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. Nonfunction 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. 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. 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, nonconductive, 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.1 1. U.S. Department of Health and Human Services.
