Warnings and Cautions • Federal law restricts this device to sale by or on the order of a physician. • When unplugging the unit, do not pull on the power cord itself. This may damage wiring inside the cord. Pull the connector housing only. • When disconnecting the handpiece, do not pull the cord itself. This may cause damage to the internal wiring. Pull on the connector housing only. • Do not clean by ultrasonic means! Use of ultrasonic cleaning equipment may damage the handpiece and will void the product warranty. • Always remove blade/burr before sterilization of the handpiece. • To provide adequate cooling, where appropriate, for the blade/burr, to prevent accumulation of unwanted materials in the surgical site, and to prevent abnormal wear of the cutting surfaces, be certain to periodically irrigate the surgical site and the tip of the blade/burr and ensure that suction (at least 127mm hg vacuum) is flowing whenever the instrument is running. • Set pump flow so that irrigation is seen at the surgical site. (The flow of irrigating solution must exceed the level of suction.) • Avoid the use of chemical cleaning agents that might damage the silicone used in this instrument. Use a non-residue type cleaner, preferably isopropyl alcohol, or a solution of 10% mild detergent and 90% water. • Do not autoclave the handpiece unless it is thoroughly clean. • Follow cleaning instructions and use recommended brushes. • Visually inspect to ensure that no tissue, fluid, or blood has contacted the inner surfaces. • Mains disconnect device is unplugging cord. • The handpieces listed in this manual are for use with Gyrus ACMI, Inc. - ENT Division blade and burr attachments only. • Do not use sterile packaged items (blades, burrs, suction/irrigation tubing) if package seal is torn or broken. • Do not attempt to disassemble the handpiece. Failure to observe this caution will void the product warranty. • To mount the Diego controller to an IV pole, use the following height parameters. When the top of the IV pole is set to 72 inches, the top of the controller should not exceed 40 inches. When the top of the IV pole is set to 68-1/2 inches, the top of the controller should not exceed 58-1/2 inches. • Diego passed IEC 601-1-2 testing. However, do not place the Diego controller in direct contact with electrosurgery equipment or near any equipment that may emit electromagnetic fields or radio frequency. If interference is encountered, move/locate devices farther apart from each other. 1

System Description The Diego Powered Dissector & Drill System from Gyrus ACMI, Inc. - ENT Division is comprised of a console, optional powered handpieces, footswitch, tubing set and hospital grade power cord. Console –Provides power and functionality to the specified Diego and Otologic handpieces. In addition, a peristaltic irrigation pump is integrated into the controller unit to facilitate local irrigation. Footswitch – The footpedal’s loop style base allows for easy “no-look” identification, orientation and movement under the table. Lights are incorporated on the pedal for easy orientation in a darkened operating room. Footswitch allows the user to operate the Diego handpiece in the traditional way. Diego also provides the option of handpiece actuation. Handpiece – The handpiece accepts a range of one-time use cutting blades, and tissue removal and drilling burrs. The handpiece's shape takes into account the comfortable neutral hand position and is designed to reduce "cord drag" to optimize balance and reduce fatigue. The handpiece includes a proprietary fluid control design that retards contact of bodily fluids from soiling the inner surfaces of Diego. The handpiece also allows the user to aim the cutting window of the blade circumferentially with minimal arm motion. Diego uses Diego blades and burrs from Gyrus ACMI, Inc. - ENT Division. Otologic handpiece styles are available in addition to Diego, including the Stapes drill, and Viper Straight or Angled handpieces. All are lightweight and designed to provide balanced power. Consult the Owner's Manuals for Viper™ (70338030 straight, 7033-8031 angled) and Stapes Otologic Drills (7033-8032) for specific operating information. (Synergy™ Drill Systems Operations Manual) One-Time-Use Tubing Set – The disposable tubing set combines suction and irrigation tubing into one component. The tubing set snaps into place, and works in tandem with the fluid control design to speed set-up and cleaning. The tubing set is discarded at the end of the procedure. The Viper high-speed drill uses a separate tubing set that does not include suction.

Blade and Burr Set-up The Diego Handpiece (Sold separately from console) The Diego Powered Dissector handpiece (Catalog No. 7033-8010, 7033-9001) is a lightweight and powerful handpiece specifically designed for use with the Diego console, and performs to the parameters listed in Table 1. In order to operate the handpiece, chuck a single use disposable blade/burr into the chucking mechanism (one of 8 available positions). Diego includes a revolving blade chucking feature, allowing the user to orient the blade window manually. Once securely chucked, the user can manually orient the blade window orientation by rotating the nose cone left or right.

Powered Dissector Blades and Burrs Diego Powered Dissector blades/burrs are provided sterile and are single-use disposable instruments. Their hubs are designed to fit only the Gyrus ACMI, Inc. - ENT Division Diego Powered Dissector handpieces. There are various patterns, including straight, curved, smooth blades, serrated blades, and burrs.

Powered Dissector Blade and Burr Engagement A Powered Dissector blade or burr may be positioned in each of 24 different positions on Diego. The window position may be changed intraoperatively by rotating the nose cone. To engage the Powered Dissector blades/burrs: 1. Pull the sliding collet back. 2. Rotate the hub until the key aligns on the chucking mechanism. 3. Insert the plastic driver hub of the blade/burr into the handpiece until it stops completely. 4. Release the collet and firmly push the blade/burr into the handpiece until the collet springs back into its original position. 5. Pull slightly on the shaft of the blade/burr to verify engagement. 6. If the blade/burr pulls out, repeat steps 1-5. To disengage the Powered Dissector blade/burr: 1. Pull the sliding collet back. 2. Pull the blade/burr out of the handpiece. NOTE: Since the Powered Dissector blade/burr is a two-piece configuration, it is possible that the inner component may remain in the handpiece when the outer component is removed. If this happens, simply pull the inner component out. The chucking mechanism will not engage the inner component alone. The blades, burrs and tubing sets are one-time use disposable items. These items should be replaced after each surgery. Disposal of these items should comply with local hospital regulations for disposable items. 13

Suction/Irrigation Set-up Suction/Irrigation Tubing Assembly Installation 1. Inspect sterile package to assure that sterility has been maintained. 2. Remove tubing from package using appropriate sterile technique. 3. Center the tubing into the pump assembly located on the side of the console as shown on page 4, then turn the knob. When the knob handle is at the 3 o’clock/9 o’clock position, the pump is closed and ready for use. 4. Connect the spike end to a standard I.V. bag. Connect the integrated suction tube to the suction canister. Push the tubing connector into the connection port on the rear (proximal) end of the Diego handpiece until a palpable “click” is felt. Suction and irrigation is now ready to use. No additional attachment to the blade is necessary (To ensure irrigation of the surgical site, the flow of irrigating solution must exceed the level of suction.)

Cleaning and Sterilization Important Guidelines for Cleaning Thorough cleaning and rinsing is vital to reprocessing reusable medical devices. Effective cleaning must be carried out to achieve proper decontamination. All cleaning should be performed in a manner designed to minimize exposure to bloodborne pathogens. Reusable medical devices should be kept moist immediately after use until cleaning. Devices capable of disassembly must be disassembled prior to cleaning. Thorough cleaning and rinsing should be carried out as soon as possible. Manual cleaning with appropriate brushes should be done while the instrument is being rinsed (if applicable). The purpose of cleaning and rinsing is to remove all adherent visible soil and to reduce particulate matter, microorganisms and pyrogens. Furthermore, thorough rinsing is necessary to remove any residual cleaning agents from the medical devices that could protect microorganisms from destruction and reduce the lethality of the sterilization process. Medical devices that will be stored between cleaning and decontamination should be dried with low linting, non-abrasive soft cloth to prevent microbial contamination that could result from wet instruments. Console and Footswitch Wipe the outside of the console and footswitch using a soft wipe and isopropyl alcohol. Cleaning Agents and Equipment Detergents

Proteolytic enzymatic detergents with a pH range between 6.0 and 8.0 should be used. These detergents have nonionic surfactants. Detergents should be used at the concentration level recommended by the manufacturer. Note: Undiluted detergents and ones with pHs greater than 8.0 can strip the coloration from metal instruments.

Water

The quality of water should be carefully considered for use in preparing enzymatic detergents and for rinsing in the cleaning procedure. Water hardness is a concern because deposits left on medical devices may result in ineffective cleaning and decontamination. Deionized water can help prevent discoloration and staining associated with mineral residues found in tap water.

Sterile isopropyl alcohol prep pads Soft Cloths Cleaning Brushes

Used for cleaning console and footswitch. For drying handpiece. Diego Powered Dissector Cleaning Kit (7033-8009) and the Synergy Drill Cleaning Kit (7032-5512) are both available from Gyrus ACMI, Inc. ENT Division at 1-800-773-4301.

15

OBSERVE THE FOLLOWING CAUTIONS WHEN CLEANING THE HANDPIECE: • HANDPIECE SHOULD BE STERILIZED PRIOR TO FIRST USE. • CLEAN THE HANDPIECE THOROUGHLY AFTER EVERY PROCEDURE. The Powered Dissector and Drill handpiece are motorized equipment. The reliability and performance of this equipment is highly dependent on proper care and cleaning. Without proper cleaning, suction strength may be reduced resulting in diminished cutting performance. • DO NOT AUTOCLAVE THE HANDPIECE UNLESS IT HAS BEEN THOROUGHLY CLEANED ACCORDING TO THE PROCEDURES OUTLINED BELOW. Debris left in the handpiece will be much more difficult to clean and remove after heating in an autoclave. • USE WARM SOAPY WATER FOR CLEANING. Warm water is much more effective at removing blood and tissue. • DO NOT ALLOW FLUID, BLOOD, AND TISSUE TO DRY IN THE HANDPIECE PRIOR TO CLEANING OR AUTOCLAVING. • AVOID THE USE OF CHEMICAL CLEANING AGENTS, WHICH MIGHT DAMAGE THE INSTRUMENT. USE A NON-RESIDUE CLEANER, PREFERABLY ISOPROPYL ALCOHOL, OR A SOLUTION OF 10% MILD DETERGENT AND 90% WATER. • DO NOT CLEAN USING CIDEX® OR ULTRASONIC WASHERS! ANY OF THESE CLEANING METHODS MAY DAMAGE THE HANDPIECE AND WILL VOID THE PRODUCT WARRANTY.

16

Diego Handpiece Required Cleaning Equipment:

Lukewarm water, a clean, soft towel, and sterile isopropyl alcohol prep pads

Cleaning Procedure:

1. Wipe down the external surface of the hand piece with warm soapy (enzymatic, biocidal, detergent) water. 2. Using a round, small diameter, soft bristle brush, moistened with the soapy water, gently scrub the interior of the chucking mechanism, and the through channel to loosen any soil. Take care not to scratch the interior of the handpiece. 3. Holding the hand piece with the chuck end up, flush the interior of the hand piece with running water, to remove loosened soil. 4. Flush the exterior of the hand piece with running water to remove detergent and other soil. 5. Visibly inspect the exterior of the hand piece for any adherent soil. 6. Visibly inspect the interior, as far as possible, for adherent soil, paying particular attention to the chucking mechanism and crevices in and around the interior of the device. 7. Repeat if needed.

Sterilization The Diego Powered Dissector handpiece is designed for sterilization by steam autoclave. ALWAYS REMOVE BLADES BEFORE STERILIZATION OF THE HANDPIECE. IT IS CRITICAL TO PROPERLY CLEAN ALL REUSABLE DEVICES PRIOR TO STERILIZATION.
