BLADE INSTALLATION (See Figure 7)
Lubrication of the blade is not necessary. Use a new, sterile blade for each procedure. (Additional blades may be
required for extensive procedures.)
To install the blade:
• Place the the Zimmer Dermatome II handpiece throttle in the SAFE (O•) position. To place the dermatome
in the SAFE position, slide the safety lock on the throttle toward the blade end of the instrument to the
SAFE (O•) position. Only the SAFE symbol (O•) should be visible (see figure 7).
• Using the Zimmer Dermatome II screwdriver (REF 00-8851-205-00), loosen the handpiece width plate
screw. Do not remove the screw from the handpiece. If a width plate is already attached, remove by
holding both sides and sliding/lifting forward and up (see figure 7A-C). Do not lift from the front as this will
cause contact with the blade and possible injury.
• If replacing a blade, remove the used blade before inserting a new one. Refer to BLADE REMOVAL
section.
• Place entire blade/cover assembly (see figure 7D) onto the handpiece such that the blade key fits into the
notch of the handpiece, and the handpiece drive pin mates with the hole in the blade (see figure 7E).
Place your finger on the blade assembly (white portion). While holding the blade assembly, lift one end of
the blade cover (blue portion) and remove blade cover from blade assembly (see figure 7F). Retain blade
cover for blade removal after use.
• With the printing on the width plate facing out, place the width plate fl at on the face of the dermatome
head. Carefully slide back toward the screw (see figure 7G-I) , until the width plate hole is located under
the mounting screw. Do not grasp the front of the width plate as this will cause contact with the blade and
possible injury. Using the screwdriver, gently tighten the mounting screw. Do not over-tighten screw (see
Figure 7J).
• NOTE: Choose the proper width plate to satisfy cutting requirements
• Caution: Be sure the width plate is securely under the outside width plate holders, (see figure 7I). Failure
to properly install/secure the width plate may result in a patient injury.
CUTTING THE GRAFT
• Skin should be prepared in routine manner.
• It is not necessary to lubricate the skin; however, lubricating the donor site may ease travel of the Zimmer Air
Dermatome II.
• Set control lever adjustment knob pointer to desired graft thickness (see figure 6). Do not insert any instrument
between the blade and the control lever as this may damage or knick the blade causing a poor cut. Further, it
may compromise the calibration of the instrument.
• To activate the dermatome, lift the throttle lever and slide the safety lock back from the SAFE (O•) position toward
the hose coupling. The ON symbol ( |-- ) should be visible. (See figure 7). For optimum results, it is recommended
that the dermatome operate at full speed. To ensure that full speed is achieved, completely depress the throttle
control with the safety lock in the ON ( |-- ) position.
• Depress the throttle to start the dermatome. Apply the handpiece on the donor site at a 30° – 45° angle (see
figure 8). Guide the unit forward using a slight downward pressure to ensure that the cutting edge remains
continuously and firmly in contact with the donor site.
• Two methods of graft removal from the instrument may be used:
• Method I
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 throttle to the SAFE (O•) position and carefully remove the graft. (See
figure 8.)
• Method II
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 non-uniform cuts. Lift the handpiece away from the donor site to end
the graft. Return the throttle to the SAFE (O•) position. (See figure 9.)
