Micro Jigsaw MSS5000

Instructions for use

Reprocessing

restrictions

Frequent reprocessing has only a limited impact on the handpiece. The end of the products service life is normally determined by wear

and damage through use. The instrument is designed for sterilization cycles.

General handling . The micro jigsaw must be thoroughly cleaned, disinfected and sterilised before initial operation (products straight from the fac-

tory) and also immediately following each use. Only a cleaned and disinfected instrument permits proper sterilisation!

. The electronic motor should always be treated with utmost care when being transported, cleaned, serviced, sterilised and stored.

. We recommend the use of mild alkaline and enzymatic cleaners with as low a content of silicate as possible in order to avoid staining

(silicatising) the instruments.

. Only commercial grade DGHM-/VAH-listed agents may be used for cleaning and disinfection. See these agent manufacturers’ specifi-

cations for the method of use, action time and suitability of disinfection and cleaning substances.

. Follow precisely the operating instructions of the devices and chemicals etcetera, used during preparation.

. Adhere exactly to the chemical dosages, action times and exposure temperatures during cleaning and disinfection.

. The end of the products service life is determined by wear and damage through use. For the micro jigsaw it can be reached even

before the sterilization cycles, that they’re designed for, due to wear and tear.

. Do not overload washer. Avoid rinsing blind spots. Pay attention to secure storage in the machine.

. Follow the applicable regulations in your country for reprocessing medical devices.

. Only the cooling clip may be cleaned in an ultrasonic bath. The micro jigsaw must never be subjected to ultrasonic cleaning! This

will impair the functionality.

. NOUVAG recommends using a screen basket with a rinse strip from mach (NOUVAG REF ), a re-usable container for comfort-

able preparation and storage (including transport) of products. The screen basket can be used to keep products safe both during

the rinsing cycle and also during and after sterilisation until the products are used. The screen basket is suitable for use with sterili-

sation paper or a rigid sterilisation container. It has no barrier effect itself in order to maintain sterility.

Preparation at the

point of use

After surgery immediately remove blood, secretion, tissue and bone residue with a disposable cloth/paper towel, do not allow to dry!

Dried residues cause corrosion.

Safe-keeping and

transport

Contaminated products must be stored and transported to the preparation site in a closed container to avoid damaging the products

and the contamination of the environment.

Cleaning and

disinfection,

pre-cleaning

Remove saw blade, cooling tube, clips for the cooling tube attachment and cooling clip from the micro jigsaw handpiece.

. Wipe visible impurities with a moist expandable cloth/tissue paper from the micro jigsaw and accessories.

. Brush the handpiece and accessories under running tap water using a soft brush (manufacturer for example Insitumed GmbH,

REF MED.).

. Rinse the outer surface of the micro jigsaw handpiece for  seconds with a water pistol (at a pressure of at least .bar; manufac-

turer for example HEGA Medical, REF  or REF ). Local tap water is sufficient for this purpose, since the last step is always

a machine cleaning with deionized water, so possibly hard water with lime traces from the pre-cleaning cannot remain on the

handpiece.

. Rinse the cooling clip with a cleaning gun with a jet nozzle attachment (manufacturer for example HEGA Medical, REF ) for at

least seconds.

Cleaning Mechanical cleaning

. After pre-cleaning place the micro jigsaw and its accessories in the

strainer basket.

. Mechanical cleaning is only successful if the pre-cleaning, described above,

is adhered to!

. Cleaning is done using the Vario TD programme in the cleaning and dis-

infection unit (CDU). For the cleaning process it is advisable to use DI

water (fully desalinated water).

. After completing the cleaning programme (inc. Thermal disinfection)

check the micro jigsaw, the nut and the cooling clip for visible contami-

nation in grooves and gaps. Repeat the cleaning cycle, if necessary.

Disinfection Mechanical disinfection

The cleaning/disinfection unit has a thermal disinfection programme which

follows after the cleaning. When performing mechanical thermal disinfec-

tion, give due consideration to the national requirements relating to the A

value (see DINENISO-). We recommend an A value of . for the

instrument. Disinfection must be carried out with DI water.

Warning

When inadequately rinsed or exposed to the disin-

fectant or detergent for too long, the instrument can

corrode. Please see the corresponding detergent and

disinfectant’s package insert for dwell times.

Drying Mechanical drying

Dry the micro jigsaw using the cleaning/disinfection unit’s (CDU) drying cycle.

If required, manual drying can also be achieved by using a lint-free cloth.

When drying manually, take particular care with the grooves and gaps of the

instrument. Then spray the instrument again with Lubrifluid.

Every CDU must provide a corresponding drying procedure through the

manufacturer (see ISO-). Please follow the corresponding CDU-manu-

facturer’s directions and operating instructions.

Manual drying

Set up the micro jigsaw in an upright position without

the nut and the cooling clip attached.

Dry the instrument for at least minutes. Then spray

it with Lubrifluid. Afterwards reassemble the nut and

the cooling clip back onto the instrument.

Manual

cleaning and

disinfection

. Immerse the micro jigsaw handpiece after pre-cleaning for minutes in a bath with enzymatic

cleaner. Clean accessories such as e.g. the cooling clip and the nut for minutes in an ultra-

sonic bath. Follow the instructions of the manufacturer of the detergent.

. Perform a complete post-clean of the product under running drinking water, using a soft brush.

Intensely rinse, if there is any cavities and lumens existing, with a water pressure gun (or simi-

lar) for at least seconds.

. To remove the detergent, rinse the products under running city water (drinking quality) for at least

seconds.

Warning

Do not clean micro jigsaw

(handpiece) in an ultrasonic

bath!

Manual

disinfection

After cleaning, immerse the products for minutes in a bath with a suitable disinfectant. It must be ensured that all surfaces are com-

pletely wetted with the disinfectant. Follow the manufacturers instructions of the disinfectant. After disinfection thoroughly rinse all

products with deionised water to remove the disinfectant ( >min.).

Manual

drying

Set up the micro jigsaw handpiece vertically, separated from the cooling clip, to make sure the outflow of water is favored. Dry products

with a lint-free paper towel. Then dry with suitable compressed air in accordance with the RKI recommendation. Pay particular atten-

tion to the drying of hard to reach areas.

Inspection and

care

. First unscrew the union nut and remove the cooling clip.

. Perform a visual inspection for damage, corrosion and wear.

. Spray the handpiece for cleaning and care. NOUVAG recommends the use

of Lubrifluid. Attach the blue spray adapter to the spray can and spray

the handpiece from the coupling side for about seconds until only

clear liquid flows out of the electronic motor.

. Then wipe with a damp cloth (observe the instructions for use of the

product).

. After spraying the handpiece, re-install the cooling clip on the hand-

piece and screw the union nut onto the collet chuck.

Sterilisation Sterilisation of the micro jigsaw handpiece is performed with a fractionated pre-vacuum steam sterilisation technique (in accordance

with DINEN / DINEN) giving due consideration to the respective national requirements. Minimum requirements:

. Pre-vacuum phases: 

. Sterilisation temperature: minimum °C – maximum °C

. Holding time: At least minutes (full cycle)

. Drying time: At least minutes

When sterilising several products during one sterilisation cycle, do not exceed the maximum steriliser load (see manufacturer’s details).

A drying cycle must be added in the case of autoclaves without a vacuum function. After sterilisation an immaculate sterilisation result

must be detected by examining the appropriate indications. According to the Robert-Koch Institute preparation ends with the document-

ed release for use of the medical device. If the sterilised micro-pencil saw is not used immediately after sterilisation, it must be labelled

with the sterilisation date on the packaging.

Storage Storing the sterile packaging

The sterilised product must be stored away from dust, humidity and contami-

nation. During storage, direct sunlight should be safely avoided. After the

expiry date has passed, do not use the product any longer.

Handling the sterile packaging

Before taking out the product, check for the packaging

to be intact. When taking out the product, follow the

respective aseptic procedures.
