•

Place the carrier, with the skin side up, on the guidance plateau and push against the raised portion of the
guidance plateau. The guidance plateau is used to ensure straight entry into the gap between the cutter and the
knurled roller.

•

The leading end of the

Dermacarrier

II Skin Graft Carrier is firmly introduced into the

Meshgraft

II Tissue

Expansion System making sure the entry is straight. Apply firm pressure to the opposite end of the

Dermacarrier

II Skin Graft Carrier to assist the cutter in the initial engagement, as the ratchet handle is slowly turned clockwise.
(See Fig. 5.)

•

After the

Dermacarrier

II Skin Graft Carrier has been turned through approximately

in. (1.25 cm), stop and

check the cut portion of the skin graft. If the graft has not disengaged from the cutter, grasp the leading end of
the graft with forceps, and disengage the entire meshed portion of the skin from the cutter. Avoid damaging the
blades of the cutter during this action.

•

Check the uncut portion of the skin graft. The uncut portion must be kept taut at all times when turning the

Dermacarrier

II Skin Graft Carrier through the instrument.

•

Apply constant downward pressure on the leading end of the

Dermacarrier

II Skin Graft Carrier while turning it

through the

Meshgraft

II Tissue Expansion System (See Fig. 2). This is done to ensure that the skin graft will not

engage in the cutter. Rotate the ratchet handle back and forth from the 10 o’clock to the 2 o’clock position until
the carrier exits the back of the mesher. Note: The ratchet mechanism operates only when there is a carrier in
the unit.

•

Once the graft covered carrier has been transferred to the operative site, remove the meshed skin from the
carrier and expand it as desired. Apply the expanded skin to the prepared transplant site.

•

If it is necessary to remove the carrier after it has been inserted, the ratchet handle should be removed and
the back side of the handle attached to the knurled roller extension. Rotating the ratchet handle back and forth
from the 10 o’clock to the 2 o’clock position will cause the carrier to reverse direction and exit from the front of
the mesher.

CLEANING PRECAUTIONS

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

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.

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

Meshgraft

II Tissue Expansion System.

Steam sterilize the

Meshgraft

II Tissue Expansion System. Follow instructions in STERILIZATION RECOMMENDATIONS.

MANUAL AND AUTOMATED CLEANING AND DISINFECTION

PROCESS INSTRUCTIONS

•

The following instructions and charts detail the cleaning and disinfection process for the

Meshgraft

II Tissue

Expansion System.

•

Safely dispose of all used carriers in accordance with hospital policy for contaminated waste.

•

Remove excess body fluids and tissue with a disposable, non-shedding wipe and cover with a damp cloth. The
damp cloth is utilized to assist in the prevention of the un-removed soil drying prior to cleaning and disinfection
process. Body fluids and tissue should not be allowed to dry on instruments prior to cleaning.

•

Universal precautions for handling contaminated/biohazardous materials should be observed.

•

Instruments should be cleaned within 30 minutes of use to minimize the potential for drying prior to cleaning.

•

Prepare cleaning agents at the use-dilution and temperature recommended by the manufacturer.

•

Follow the Manual Cleaning Instructions (Chart 1) or the Automated Cleaning Instructions (Chart 2).

•

Following the cleaning procedure, visually inspect for damage and/or wear.

•

Check the action of moving parts to ensure smooth operation throughout the intended range of motion.

Note: If damage or wear is noted that may compromise the function of the instrument, do not use. Refer to
RETURN AUTHORIZATION AND REPLACEMENT INFORMATION section.

•

Steam sterilize only. Follow instructions in STERILIZATION RECOMMENDATIONS.
