CUTTING THE GRAFT
1. Lubricating the donor site with sterile mineral oil or other
lubricant may ease the travel of the
Zimmer
Tissue Bank
Dermatome.
2. Hold the handpiece on the donor site at a 30–45 degree
angle.
3. Depress the on/off lever to start the cut. Guide the unit
forward using a slight downward pressure to ensure that
the cutting edge remains in contact with the donor site.
4. Two methods of graft removal may be used:
a. Method I (see Fig. 11): Allow the cut graft to
accumulate in the pocket of the handpiece. Lift the
handpiece away from the donor site to end the graft
Return the on/off lever to the
SAFE
position and
carefully remove the graft.
b. Method II (see Fig. 12): Use tissue forceps to gently
lift the graft as it emerges from the pocket area.
DO
NOT
stretch or pull the graft as this causes irregular
edges and nonuniform cuts. Lift the handpiece away
from the donor site to end the graft. Return the on/off
lever to the
SAFE
position.
5.
DO NOT
run the
Zimmer
Tissue Bank Dermatome
without cutting for an extended time. Release the on/off
lever and return the safety lock to the
SAFE
position
between cuts to remove the graft.
CLEANING PRECAUTIONS
See Fig. 13–15.
DO NOT LUBRICATE THE
ZIMMER
TISSUE BANK
DERMATOME.
The dermatome contains sealed bearings.
No lubrication is necessary.
NEVER IMMERSE THE
ZIMMER
TISSUE BANK
DERMATOME
in liquid chemical disinfectants, detergent
solutions, or rinse water. Some solutions will corrode the
metal, delicate moving parts, and seals.
DO NOT
process the dermatome handpiece or cord in a
washer/sterilizer.
NEVER CLEAN THE DERMATOME IN AN ULTRASONIC
CLEANER.
Ultrasonic cleaning will dislodge oil from the
internal bearings and render the instrument inoperative.
HANDLE THE
ZIMMER
TISSUE BANK DERMATOME
CAREFULLY.
Should it be dropped or damaged, it should
be returned to an authorized Zimmer Orthopaedic Surgical
Products service center to ensure the integrity of
calibration.
NEVER STERILIZE OR IMMERSE THE POWER SUPPLY.
CLEANING INSTRUCTIONS
Clean the power supply with a damp, lint-free cloth using a
mild detergent. An alcohol wipe may be used to disinfect
the surface of the power supply.
NEVER IMMERSE
the
power supply.
Safely dispose of all used blades. Thoroughly scrub the
dermatome and width plate(s) with a soft brush and mild
detergent. All traces of blood, coagulated material, stains,
etc. should be removed.
Rinse all detergent from the dermatome and width plate(s)
under a faucet.
DO NOT IMMERSE IN LIQUID.
Shake the dermatome and width plate free of water and
wipe with a clean, lint-free cloth. An alcohol wipe may be
used to disinfect the surface of the dermatome before
steam sterilization.
Steam sterilize the
Zimmer
Tissue Bank Dermatome
handpiece, width plates, and screwdriver. Follow the
instructions in the STERILIZATION RECOMMENDATIONS
section.
Always inspect the handpiece carefully for possible
scratches, nicks, or burrs. Inspect the dermatome’s cord for
cuts or missing insulation caused by extended use or
mishandling. If necessary, return for service to an
authorized Zimmer Orthopaedic Surgical Products service
center.
STERILIZATION RECOMMENDATIONS
Steam sterilization is safe and effective, and is the only
recommended method for the dermatome. There are no
contraindications for steam sterilizing the
Zimmer
Tissue
Bank Dermatome handpiece.
NEVER
sterilize the power supply. Disconnect the
dermatome from the power supply before sterilization.
Place cleaned instruments in an instrument tray or fully
perforated autoclave case. The
Zimmer
Tissue Bank
Dermatome Autoclave Case (REF 8831-03) is recommended.
DO NOT
kink or crimp the dermatome’s cord when closing
the case lid.
If the instruments are to be wrapped, two double thicknesses
of #140 thread count wrappers, or equivalent, should be
utilized. Exposure times are the same for wrapped or
unwrapped instruments.
Follow the instructions for prevacuum steam sterilization or
gravity air displacement steam sterilization listed below.
Prevacuum Steam Sterilization
If your prevacuum steam sterilizer has prefixed cycles, use
the "hard goods" cycle.
If it does not have a prefixed cycle:
1. Set temperature at 270–272°F (132–133°C).
2. Set exposure time for 4 minutes.
3. Set drying time for 8 minutes minimum.
Gravity Air Displacement Steam Sterilization
1. Set the temperature and corresponding exposure time as
follows:
270–272°F (132–133°C) 35 minutes
250–254°F (121–123°C) 60 minutes
2. Set the drying time for 8 minutes minimum.
DO NOT IMMERSE
in liquid to cool. Cool by exposure to
room temperature or cover with a cold, sterile towel.
