Usage instructions
This section provides step by step instructions as well as safety information and
recommendations for the safe and effective use of the product during surgery.
Before use
All instruments should be verified for proper function before each clinical use. The user
must be familiar with the instrument function before clinical application. Stryker recommends the use of silicon free, non-mineral oil based lubricant for maintenance of articulated
instruments
4.1
Plate/screw forceps
These forceps function as self-retaining forceps when the prongs are placed in the holes of
the plate. They also allow holding of the plate in place while drilling to place the first screw.
4.2
Bender/cutter
WARNING
Excessively aggressive use of bending instruments may cause recognizable macroscopic
damage to the implant (indentations, elongated screw holes, etc). Deformed plate holes signify not only an increased risk of breakage in these areas but also impair the accurate fit of
the screw head to the plate.
Titanium hardness increases and ductility (bendability) decreases due to cold working during the bending process. This may lead to product failures such as postoperative plate fractures and therefore may lead to patient harm.
XX Ensure that the desired shape of the implant is reached in as few bends as possible.
XX Avoid excessive bending.
XX Avoid acute angles together with small bending radii.
XX Straight plates may not be used and contoured for use around the mandibular angle.
XX Plates that have been severely bent and re-bent must be discarded.
XX Plates with visible damages or deformed plate holes must be discarded.
XX Do not use the 3-prong bender with the locking plates.
9/29
Page 13
Usage instructions
WARNING
Cutting the implant may reduce the stability of the implant. This may lead to product
failure, injury and therefore to patient harm.
XX Only cut the implant if necessary and in a way that adequate strength and fixation for
the intended use is maintained.
XX If the product is damaged then dispose of the product.
A cut bone plate segment intended to be implanted may have sharp edges. Cutting may lead
to the creation of small particles. Both may cause soft tissue injuries or irritations.
XX Deburr the cut segments.
XX Upon cutting a template, wipe the abrasive surface of the template and the cutting instrument clean of potential particles prior to use on the patient or use with the implants.
XX Perform any required modification of the plate away from the surgical site.
XX Prevent generated particles from entering the patient.
Using the plate cutter may cause uncontrolled movement of the cut plate segment. This may
lead to patient harm.
XX Hold the unfixed portion of the plate with the forceps.
CAUTION
XX Hold the plate cutter at the base of the handle to prevent any inadvertent hand pinching
during operation.

Reprocessing
●● It is the responsibility of the user facility to make sure that appropriate cleaning and
disinfection methods are used where Stryker recommendations are not followed.
●● New products must be carefully cleaned before initial sterilization. Trained personnel
must perform cleaning (manual and/or machine cleaning, ultrasound treatment, etc.)
along with maintenance and mechanical inspection prior to initial sterilization.
●● Exact compliance with the equipment manufacturers’ user instructions and recommendations for chemical detergents is required. Stryker recommends only the use of neutral
pH cleaning and disinfecting agents.
●● Contamination by non-conventional transmissable agents, e.g. vCJD (variant
Creutzfeldt-Jakob-Disease), in accordance with the system indications for use, in particular through contact with lymphatic tissue, is possible. Stryker recommends to incinerate any product that is suspected to have been contaminated by non-conventional
transmissible agents.
5.1
Decontamination and cleaning process
A. Manual decontamination and cleaning:
1. Preparing the bath
●● Dilute the decontaminating – cleaning detergent in running water according to the
detergent manufacturer’s instructions, preferably at 40 °C (105 °F). Temperature
should not exceed 50 °C (122 °F). Stir the mixture to homogenize the solution.
2. Instruments
●● Handle instruments with care. Do not let them knock against each other.
3. Soaking
●● Soak instruments and containers immediately after use. If a sticky substance remains
on the instrument or container, wipe it with single-use paper soaked in 70 % alcohol.
Using a syringe, aspirate and squirt the soaking solution several times into grooves
and holes in order to push out any substances that might prevent liquid from penetrating through the entire instrument or container. After the preparation phase, immerse the instruments and containers in the decontamination solution. Make sure that
the instrument or container is completely submerged. Soak for 15 minutes.
WARNING
Soaking for more than 15 minutes could cause instruments and containers to corrode.
21/29
Page 25
Reprocessing
4. Manual cleaning
●● Brush the instrument or container vigorously using an appropriate polishing brush
(see Table 1) to remove any debris present on the device. Pay particular attention to
rough surfaces and features where soil may be shielded from the brushing as well as
cannulations, blind holes, hinges and joints between mating parts.
5. Rinsing instruments and containers
●● Rinse the instrument or container thoroughly in running water until it is no longer
slippery to the touch. Close attention should be paid to this process, since the quality
of the remaining steps depends upon it. Repeat steps III and IV if soil is still visible.
Drain the instrument or container on single-use blotting paper.
6. Moving the instruments to the cleaning area
●● If the ultrasound cleaning area is different from the decontamination area, rinsed instruments and containers must be transported in a closed system, either a covered pan
or a heat-sealed bag. This prevents contamination during transfer.
B. Ultrasound cleaning for instruments:
1. Preparing the ultrasound bath
●● Dilute the decontaminating-cleaning detergent in the ultrasound tank according to the
detergent manufacturer’s instructions at 40 °C (105 °F). Stir the mixture to homogenize
the solution.
2. Instrument handling
●● Handle instruments with care. Do not let them knock together. Avoid mixing instruments and containers in good condition with those whose surfaces are damaged.
3. Soaking and ultrasound action
●● After the decontamination phase, immerse the instruments in the decontaminatingcleaning solution in the ultrasound tank. Make sure that the instruments do not overlap and that the instruments are completely submerged. Cleaning lasts 15 minutes.
When the ultrasound bath solution is renewed, it must be ultrasonically degassed for
5 minutes. After the 15 minutes of ultrasound, brush the instrument vigorously using an appropriate polishing brush (see Table 1) to remove any debris present on the
device.
4. Rinsing the instruments
●● Rinse the instruments thoroughly in sterile purified (European Pharmacopoeia 6th
edition or USP 33) water at ambient temperature. Repeat step III if soil is still visible.
Drain the instruments on single-use blotting paper.
5. Drying
●● Dry the instruments and containers using single-use blotting paper or medical compressed air (European Pharmacopoeia 6th edition or USP 33).
