Procedure: Clean Tools
This page details how to clean surgical instruments.
- Wear appropriate protective gloves, eyewear and clothing when handling biologically contaminated instruments.
- Instruments manufactured from different metals or with special coating should be processed separately to avoid electrolytic action between the different metals.
- Do not soak instruments in hot water, alcohol, disinfectants or antiseptics to avoid coagulation of mucus, blood or other body fluids. Do not exceed two hours soaking in any solution.
- Do not use steel wool, wire brushes, pipe cleaners or abrasive detergents to remove soil as these will damage the instrument and lead to corrosion.
Equipment
- Pre-cleaning solution (optional; I haven't found a good one yet)
- Clean toothbrush or other soft-bristled brush
- PH-neutral detergent
- Bowl to submerge instruments in
- Ultrasonic cleaner (optional, for more thorough cleaning. I have a Branson 1510R-MTH because I found it cheap on ebay)
- Lubricant (if moving parts, e.g. forceps)
- Distilled water (optional)
- Soft, absorbent, non-linting towel
Process
- PRECLEANING: If instruments have just been used in a procedure and have biological soil, keep them moist and do not allow blood and/or bodily fluids to dry on the instruments. Use an appropriate pre-cleaning solution.
- Fill ultrasonic cleaner with warm water and detergent. Turn heat on and set timer to 5-10 to allow it to degas.
- RINSE: Rinse instruments thoroughly under warm water.
- MANUAL CLEANING
- Fill bowl with warm water and detergent
- Using a small, clean brush, remove soil from all surfaces of instrument while fully immersed in solution
- Put items in ultrasonic tray once cleaned
-
ULTRASONIC CLEANING
- Open or disassemble instruments as appropriate.
- Put wire tray with instruments in cleaner, run for 10 minutes
- RINSE AND DRY: Rinse all instruments thoroughly with distilled water to remove debris and cleansing agents. Make sure all internal ratchets are thoroughly rinsed. Use a soft, absorbent towel/cloth to thoroughly dry external surfaces. Compressed air may be used to aid the drying process.
- LUBRICATE: Use a water soluble instrument lubricant that is compatible with the method of sterilization before instruments are sterilized.
- After cleaning instruments, apply lubricant to all joints and movable mating surfaces to keep them moving freely and aid in protecting surfaces from mineral deposits.
Now you can Proc > Sterilize tools if needed.
