BEFORE OPERATION
Connect the Zimmer Tissue Bank Dermatome to its power
supply by inserting the connector plug into the connector
receptacle. (See Fig. 8.) Disconnect the power supply from
the power source before inserting. Remove any kinks or
twists from the cord. Align the connector plug to the
receptacle by rotating the plug while gently pushing inward.
When aligned, push in until the plug clicks into the
receptacle.
To remove the connector plug, pull outward on the outer
collar portion of the plug to separate the plug from the
receptacle.

T
the power source. Remove the fuse drawer by lifting up on
the tab using a tool and pulling the drawer outward. (See
Fig. 9.) Replace the fuse drawer with the correct fuses
installed. The correct fuse type is listed in the SERVICE
INFORMATION section. The unit is shipped with a 0.25 in.
(6.35 mm) x 1.25 in. (31.75 mm) fuse drawer installed. A
separate fuse drawer is supplied for 0.197 in. (5 mm) x
0.787 in. (20 mm) fuses.
Before connecting the power supply to a power source, be
sure that the switch on the front of the power supply is in
OFF (O) position, and that the safety lock is in the

To avoid any injury, use extreme caution when handling the
blade.
Use extreme caution when handling the dermatome with
the blade installed. Before using, always inspect the cord
for signs of wear or damage. A worn or damaged cord
must be returned for service immediately for continued
safety.
Use only Zimmer Tissue Bank Dermatome Blades
(REF 8831-000-10). Zimmer Tissue Bank Dermatome
Blades have been specifically designed for use with the
Zimmer Tissue Bank Dermatome. Other blades will not
fit properly in the dermatome and may cause
deeper grafts than selected.
OPERATING INSTRUCTIONS
1. Place the power supply in the OFF (O) position. Place
the dermatome in the SAFE position by sliding the safety
lock on the on/off lever toward the blade end of the
instrument to the SAFE position. Only the word SAFE
should be visible.
2. Choose the proper width plate to satisfy cutting
requirements. Two width plates are supplied: 3 and 4 in.
(7.6, and 10.2 cm).
3. Install the blade. (Refer to Blade Placement diagram,
(Fig. 7.) Use caution when inserting the blade to avoid
nicking it, which may result in an uneven cut. Use a new
sterile blade for each procedure.
a. Place the on/off lever in the SAFE position.
b. Using the Zimmer screwdriver (REF 8803), loosen the
width plate screws approximately two turns. DO NOT
remove screws from handpiece.
c. Remove width plate and used blade.

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/of

the cutting edge remains in contact with the donor site.
f lever to start the cut. Guide the unit
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.
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.
DO NOT IMMERSE IN LIQUID.
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

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
1. Set the temperature and corresponding exposure time as
follows:
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.
