Zimmer™ Air Dermatome Instruction Manual

INDICATIONS FOR USE

The Zimmer Air Dermatome is a skin grafting instrument that is intended to provide variable graft thickness and width capabilities.

DESCRIPTION

The Zimmer Air Dermatome (See Fig. 1, 2) is an air-powered surgical skin grafting instrument. The thickness control adjustment ranges from 0 to .030 in. (0.75 mm) in 0.002 in. (0.050 mm) increments.

Individual graft widths of 1 in., 1.5 in., 2 in., 3 in. and 4 in. (2.5 cm, 3.8 cm, 5.1 cm, 7.6 cm, 10.2 cm) are obtained with five width plates. (See Fig. 19.) Two stainless steel machine screws secure the plates to the underside of the instrument. The plates are easily fastened and removed with the screwdriver provided.

The dermatome has a self-cooling rotary vane air motor. The motor is powered by water-pumped compressed dry nitrogen (99.97% pure) or by medical-grade compressed air and provides nearly vibration-free power.

Note: Use only the supplied air hose or one having a probe conforming to BSI 5682 for high pressure medical-grade compressed air.

The Zimmer Air Dermatome should be operated at 100 PSI (690 kPa) for maximum operating efficiency and should be monitored with the operating pressure gauge of the regulator. When using the recommended hose, pressure must be set with the instrument running to avoid excessively low operating pressures.

WARNINGS AND PRECAUTIONS

To avoid serious injury to the patient and operating staff while the Zimmer Air Dermatome is in use, the user must be thoroughly familiar with its function, application and instructions for use.

To avoid injury, use extreme caution when handling the blade or when handling the dermatome with the blade installed.

Use caution when inserting blade to avoid nicking it, which may result in an uneven cut. To avoid blade damage, place dermatome blade side up when not in use.

The throttle must be in the SAFE position before changing blades or hoses, or when the instrument is not in use. Accidental activation of the instrument during these procedures may injure the patient or operating staff. To ensure that the instrument is in the SAFE position, the safety lock on the throttle should be toward the blade end of the dermatome and only the word SAFE should be visible.

Use only Zimmer Dermatome Blades (REF 00-8800-000-10). The Zimmer Dermatome Blade has been specifically designed and engineered for use with the Zimmer Air Dermatome. Other blades may not fit properly in the dermatome and may cause serious injury. Use of non-Zimmer Dermatome Blades can cause the dermatome to take grafts deeper than what the user has selected.

Handle the Zimmer Air Dermatome carefully. Should it be inadvertently dropped or damaged, it should be returned for service. Do not use.

Do not use a worn or damaged hose. Under pressure, a severed or broken hose can whip out of control.

Be sure the hose is securely fastened to the instrument so that the hose will not fall against a hard surface and become damaged.

Never use standard compressed air with the Zimmer Air Dermatome. Standard compressed air directly from a compressor can contain impurities, oils, and moisture that can damage the dermatome.

The automatic shut-off valve in the end of the hose permits removal of the hose under pressure. Use care to prevent dirt or debris from entering the end of the handpiece when the handpiece and hose are separated.

Never operate the Zimmer Air Dermatome above recommended pressures. Excessive pressure may cause internal damage and exert unusual stress on the hose.

The user and operating staff must always pay close attention to the CLEANING PRECAUTIONS and CLEANING INSTRUCTIONS FOR THE DERMATOME. Failure to follow these instructions may damage the dermatome.

IMPORTANCE OF THE NEED TO ADHERE TO A CARE REGIMEN

The handpiece and accessories must be inspected prior to each use.

CLEANING PRECAUTIONS

All subsequent cleaning and sterilization steps are facilitated by not allowing blood, tissue debris, or disinfectants to dry on used instruments.

Handle the Zimmer Air Dermatome carefully. Should it be inadvertently dropped or damaged, it should be returned for service.

Refer to NEED TO ADHERE TO CARE REGIMEN section.

Do not lubricate the Zimmer Air Dermatome. Lubrication may cause extensive damage to the motor.

Never immerse the dermatome in any solution. Some solutions will corrode the metal and delicate moving parts and also break down the internal lubricants.

Never immerse the dermatome in liquid chemical disinfectant.

Cleaning agents with chlorine or chloride as the active ingredient are corrosive to stainless steel and must not be used. Saline solution has a corrosive effect on stainless steel and should not be used.

Do not process the dermatome handpiece or accessories in an automatic washer/sterilizer.

Never clean in an ultrasonic cleaner. Ultrasonic cleaning will dislodge oil from the bearings and render the instrument inoperative. Ultrasonic cleaning may affect calibration of the Zimmer Air Dermatome.

Never sterilize the regulator or immerse it in any solution.

Steam sterilize the Zimmer Air Dermatome and accessories (except regulator). Follow instructions in STERILIZATION RECOMMENDATIONS.

STERILIZATION RECOMMENDATIONS

Steam sterilization is safe and effective and is the only recommended method for the dermatome. There are no contraindications for sterilizing the Zimmer Air Dermatome and accessories.

Ethylene oxide sterilization is not recommended because reliable outgassing times are difficult to determine for lubricated powered instruments.

Flash sterilization (10-minute exposure in a gravity displacement sterilizer in an open tray at 270° F [132° C]) is not recommended for the Zimmer Air Dermatome as this method may not provide sterility throughout the instrument.

•

Place cleaned instruments in an instrument tray or fully perforated autoclave case. The Zimmer Dermatome Autoclave Case (REF 00-8801-003-00) is recommended. (See Fig. 14.)

If the Zimmer Dermatome Autoclave Case is used, the instruments are to be wrapped, two double thicknesses of #140 thread count wrappers, or equivalent. If sterilization wraps are used, they must be free of detergent residues. Foam sheets should not be reused. They may have trapped impurities from the steam supply, and subsequently may form deposits on the instruments. Textiles that have been scorched by overheating also may form deposits on instruments. Exposure times are the same for wrapped or unwrapped instruments.
