The Zimmer Tissue Bank Dermatome is an electrically
powered instrument designed specifically for tissue
retrieval procedures. It is intended for use on cadavers
only, and not for living patients requiring skin grafts.
This instrument is designed for retrieving tissue in
thicknesses ranging from 0 to .060 in. (0 to 1.52 mm) in
.004 in. (.102 mm) increments. It also allows a choice of
either 3 or 4 in. (7.6 and 10.2 cm) skin widths using the
two width plates included. 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.
After receiving the Zimmer Tissue Bank Dermatome,
examine the unit for external signs of damage. Retain all
packing material until the contents have been verified and
an initial operational check has been performed. If the
device has been damaged, forward an immediate request
to the delivering carrier to perform an inspection and
prepare a "Concealed Damage" report. The terms of all
Zimmer Orthopaedic Surgical Products sales agreements
concerning this unit are F.O.B., Dover, Ohio, U.S.A., and
the responsibility of Zimmer Orthopaedic Surgical Products
ends with delivery to the first carrier. Thereafter, the
shipment becomes the property of the customer. Any
claims for loss, damage, or non-delivery must be made
against the delivering carrier within 10 days of shipment.
This dermatome is powered by an ironless rotor, low
inertia motor, which provides nearly vibration-free power.

ZIMMER TISSUE BANK DERMATOME
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.
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.
See Fig. 5–7.
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).
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
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.
To remove the connector plug, pull outward on the outer
collar portion of the plug to separate the plug from the
b. Using the Zimmer screwdriver (REF 8803), loosen the
width plate screws approximately two turns. DO NOT
remove screws from handpiece.
To replace input fuses, disconnect the power supply from
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.
c. Remove width plate and used blade.
d. Place a new blade onto the carriage.
e. Align the two holes in the blade with the two pins on
f. Place width plate over blade and tighten screws.
Before connecting the power supply to a power source, be
sure that the switch on the front of the power supply is in
the OFF (O) position, and that the safety lock is in the
SAFE position. Connect to a power source via the "IEC"
connector in the rear of the power supply
4. Control lever adjustment determines graft thickness. (See
Fig. 10.) Factory markings indicate 0.004 in. (0.102 mm)
divisions. Set control knob pointer to desired thickness.
A semi-annual calibration check by an authorized
Zimmer Orthopaedic Surgical Products service center
is recommended to verify continued accuracy.
Turn power on to the power supply by moving the rocker
switch on the front of the power supply to the ON (I)
position. The rocker switch should illuminate. Move the
safety lock to the ON position and briefly depress the on/off
lever to ensure that power is being applied to the
handpiece, and that the carriage is oscillating. Return the
safety lock to the SAFE position.
5. To activate the dermatome, place the power supply in the
ON (I) position. Lift the on/off lever and slide the safety lock
back to the ON position. Depress the on/off lever to start
the motor. DO NOT run the dermatome without cutting
for an extended time, as this needlessly wears the blade.
CUTTING THE GRAFT
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.
1. Lubricating the donor site with sterile mineral oil or other
lubricant may ease the travel of the Zimmer Tissue Bank
Rinse all detergent from the dermatome and width plate(s)
under a faucet. DO NOT IMMERSE IN LIQUID.
2. Hold the handpiece on the donor site at a 30–45 degree
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
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:
Steam sterilize the Zimmer Tissue Bank Dermatome
handpiece, width plates, and screwdriver. Follow the
instructions in the STERILIZATION RECOMMENDATIONS
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.
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
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.
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.
See Fig. 13–15.
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 LUBRICATE THE ZIMMER TISSUE BANK
DERMATOME. The dermatome contains sealed bearings.
No lubrication is necessary.
DO NOT kink or crimp the dermatome’s cord when closing
the case lid.
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.
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
DO NOT process the dermatome handpiece or cord in a
Follow the instructions for prevacuum steam sterilization or
gravity air displacement steam sterilization listed below.
NEVER CLEAN THE DERMATOME IN AN ULTRASONIC
CLEANER. Ultrasonic cleaning will dislodge oil from the
internal bearings and render the instrument inoperative.
