Care of Your Instruments Top
1. Use instruments only for the purpose they are designed for.
2. Handle instruments gently - avoid dropping, striking or overstraining.
3. Clean instruments and wash thoroughly with distilled or demineralized water or low sudsy near neutral detergent solution using a nylon brush or scrubber to remove blood and dirt from box locks, ratchets, hinges etc. Clean instruments immediately after use to prevent staining. Never use saline solution for cleaning. If necessary, instruments may be soaked in Haemosol to remove blood stains before washing.
4. Do not use steel wool, wire brushes, highly acidic or alkaline corrosive or abrasive cleaners or detergents. The passive protective film, which forms on the surface of stainless steel instruments through constant use, repeated washing drying and sterilization is liable to be damaged.
5. Keep box locks and ratchets open when cleaning and sterilizing instruments. Disassemble all instruments with removable parts.
6. Immediately after cleaning dip instruments in a water-soluble lubricant such as Instrument Milk, Preplube etc. Do not rinse or wipe off - the protection film of the lubricant should remain on the instrument throughout sterilization and storage. If ultrasonic cleaning methods are used it is essential to lubricate with Instrument Milk.
7. Thoroughly dry the instruments particularly in the box locks, hinges and crevices before wrapping them. Take a little extra special care of your mat finished instruments.
8. Make sure your reusable instrument wrappers are rinsed thoroughly to remove all residues of the detergents used for laundering.
9. Never put stainless steel instruments and plated instruments together in the ultrasonic cleaner. Prevent any electrolytic corrosive action due to dissimilar metals in a fluid.
A few words on Tungsten Carbide tipped instruments Top
10. Tungsten Carbide tipped instruments are specially susceptible to damage if highly alkine or acidic detergents or cleaning solutions are used. Ensure that they are near neutral.
Light or dark spots Top
11. Use of ordinary tap water and not thoroughly drying the instrument may create these spots.
Use only distilled or demineralalized water.
Brown stains Top
12. Brown stains may develop on the instruments These can be minimized by using distilled or de
mineralized water for cleaning.
Blue stains Top
13. These are usually the result from cold sterilizing solutions. Prepare the solution to exact
proportions and change as directed by the manufacturer. Prolonged use will make the
solution corrosive. Use of distilled or demineralized water and a rust inhibitor will minimize
discolouration.
Purplish-Black stains Top
14. May result from contact with ammonia. Many cleaning compounds contain ammonia which
remains on the Instrument if not rinsed thoroughly. Can also result from amine deposits
traced in the autoclave or steam pipes. Follow autoclave cleaning with a cycle of distilled water.
Rust spots Top
15. It is unlikely that surgical grade stainless steel will rust. What appears as rust is actually
residual organic matters or mineral deposits in box locks, ratchets, serrations, hinges etc.
which have been baked on to the surface.
16. Sterilization of stainless instruments together with plated instruments of dissimilar material
should be avoided.
17. A rust-coloured film on instruments can be caused by the high mineral content or by the use of water softeners.
Corrosion Top
18. Presence of blood and dirt in box locks, ratchets, serrations, hinges etc. can cause corrosion. More care should be taken in cleaning. Excessive moisture left on the surface of the instrument can lead to corrosion. Preheat the autoclave; do not rush the drying time.Foreign matters deposited in the autoclave can result in spotting and corrosion of instruments.
19. Inner surfaces of the autoclave should be given a routine maintenance. Wipe down with acetic acid (equal parts of vinegar and distilled water) to remove any impurities.
20. Stress corrosion can be caused by not opening box locks during sterilization procedure. The heating-up and cooling-down process during sterilization causes tension in the material.
Pitting Top
21. When instruments are exposed to saline solutions, blood, iodine, potassium chloride and other compounds pitting will occur. Instruments should be rinsed thoroughly immediately
after exposure.
22. Pitting can also be traced to detergents with a high pH level (B-9) used for instrument cleaning. Instruments should be thoroughly rinsed after cleaning.
23. It is impossible to completely restore an instrument after pitting or rust has eroded the hard surface. The instrument should be replaced immediately as a pitted instrument is far more susceptible to further corrosion.
