Safety measures

Intended use / indication

The saws are intended for bone-working surgery. This includes ENT surgery, maxillofacial surgery, plastic surgery, neurosurgery and hand surgery. With the bone saw

and clamped saw blade (standalone medical device), a piece of bone is removed to correct misalignments. In dental facilities, this is used in jaw osteotomy to convert

the jawbone. The saws may only be operated by expert and trained personnel. The intended use is obvious to the trained user.

Contraindication / Limitations

Relative or absolute contra indications can arise from the general medical diagnose, or in special cases by a signiﬁcantly increased risk to the patient through the use

of motor-driven systems. Relevant cases in the literature must be taken into consideration.

Reprocessing instructions

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 dam-

age through use. The instrument is designed for 250 sterilization cycles.

General handling 1. The micro saw must be thoroughly cleaned, disinfected and sterilised before initial operation (products straight from the factory) 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.

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

tising) the instruments.

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

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

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

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

7. The end of the product service life is determined by wear and damage through use. The micro saw is designed for 250 sterilisation cycles.

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

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

10. Only the cooling clip may be cleaned in an ultrasonic bath. The micro saw must never be subjected to ultrasonic cleaning! This will impair

the functionality.

11. Nouvag AG recommends using a screen basket with a rinse strip from 3mach (NOUVAG REF 51401), a re-usable container for comfortable

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

cle and also during and after sterilisation until the products are used. The screen basket is suitable for use with sterilisation paper or a rigid

sterilisation container. It has no barrier eect itself in order to maintain sterility.

Attention! In relation to patients with Creutzfeldt Jakob disease or its variant (vCJK) no responsibility can be assumed for re-use of the micro saw. The

Robert-Koch Institute recommends removing used products from circulation after use in order to avoid infecting other patients, users and

third parties.

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 saw handpiece.

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

2. Brush the handpiece and accessories under running tap water using a soft brush (manufacturer Insitumed GmbH, REF MED100.33).

3. Rinse the outer surface of the micro saw handpiece for 10 seconds with a water pistol (at a pressure of at least 2.0 bar; manufacturer for

example HEGA Medical, REF 6010 or 7060). Local tap water is sucient 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.

4. Rinse the cooling clip with a cleaning gun with a jet nozzle attachment (manufacturer HEGA Medical, REF 4270) for at least 30 seconds.

Disinfection Mechanical disinfection

The cleaning/disinfection unit has a thermal disinfection programme which follows

after the cleaning. When performing mechanical thermal disinfection, give due consid-

eration to the national requirements relating to the A0 value (see DIN EN ISO 15883-1).

We recommend an A0 value of 3,000 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 saw 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 instru-

ment again with NouClean spray.

Every CDU must provide a corresponding drying procedure through the manufacturer

(see ISO 15883-1). Please follow the corresponding CDU-manufacturer’s directions and

operating instructions.

Manual drying

Set up the micro saw in an upright position without

the nut and the cooling clip attached.

Dry the instrument for at least 30 minutes. Then

spray it with NouClean spray. Afterwards reassemble

the nut and the cooling clip back onto the instrument.

Manual cleaning

and disinfection

1. Immerse the micro saw handpiece after pre-cleaning for 15 minutes in a bath with enzymatic cleaner (for ex-

ample 2 % ID 215, Dürr Dental). Clean accessories such as e.g. the cooling clip and the nut for 15 minutes in an

ultrasonic bath (1 % ID215). Follow the instructions of the manufacturer of the detergent.

2. 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 similar) for at least 30 seconds.

3. To remove the detergent, rinse the products under running city water (drinking quality) for at least 30 seconds.

Warning

Do not clean micro saw

(handpiece) in an ultra-

sonic bath!

Manual

disinfection

After cleaning, immerse the products for 5 minutes in a bath with a suitable disinfectant (for example 2 % ID 212, Dürr Dental). It must be en-

sured that all surfaces are completely wetted with the disinfectant. Follow the manufacturers instructions of the disinfectant.

After disinfection thoroughly rinse all products with deionised water to remove the disinfectant ( > 1 min.).

Manual

drying

Set up the micro saw 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 attention to the drying

of hard to reach areas.

Inspection

and care

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

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

3. In the next step, spray the saw handpiece for cleaning and care. Nouvag AG recommends the

use of NouClean spray. Place the spray attachment (REF 1958) on the spray can and spray the

saw handpiece from the coupling side with NouClean spray for about 3 seconds until only clear

liquid escapes from the saw handpiece.

4. Then wipe with a damp cloth (observe the instructions for use of the product).

5. After spraying the saw handpiece, re-install the cooling clip on the saw handpiece and screw the

union nut onto the collet chuck.

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

EN 556-1/DIN EN ISO 17665-1) giving due consideration to the respective national requirements.

Minimum requirements:

1. Pre-vacuum phases: 3 3. Holding time: At least 3 minutes (full cycle).

2. Sterilisation temperature: At least 132°C. 4. Drying time: At least 20 minutes (max. 30 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 post-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 documented

release for use of the medical device.

Storage Storing the sterile packaging

The sterilised product must be stored away from dust, humidity and contamination.

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 packag-

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

the respective aseptic procedures.
