Immediately after surgery, rinse instruments under warm (not hot) running water. Rinse should remove all blood, body fluids & tissues.


  • Disassemble device, if device is able to be disassembled, prior to cleaning.
  • Open devices with ratchets, box locks or hinges.
  • Remove sharp devices for manual cleaning or place into a separate tray.
  • Lumens / Cannula of devices should be manually processed prior to cleaning. Lumens Cannula should be brushed thoroughly using appropriately sized soft-bristled brushes & twisting action.
  • Use cold tap water to rinse devices.


  • Use stiff plastic cleaning brushes (nylon, etc.). Do not use steel wool or wire brushes except specially recommended stainless steel wire brushes for instruments such as bone files, or on stained areas in knurled handles.
  • Use only neutral PH (7) detergents because if not rinsed off properly, low PH detergents will cause breakdown of stainless protective surface and black staining. High PH detergent will cause surface deposit of brown stain, which will also interfere with smooth operation of the instrument.
  • Brush delicate instruments carefully and, if possible, handle them totally separate from general instruments.
  • Make sure all instrument surfaces are visibly clean and free from stains and tissue.
  • After scrubbing, rinse instruments thoroughly under running water. While rinsing, open and close Scissors, Hemostats, Needle Holders and other hinged instruments to make sure the hinge areas are rinsed out, as well as the outside of the instruments.


  • Instruments should be processed in a cleaner for the full recommended cycle time usually 5 to 10 minutes.
  • Place instruments in open position into the ultrasonic cleaner. Make sure that “Sharp” blades do not touch other instruments.
  • All instruments have to be fully submerged.
  • Do not place dissimilar metals in the same cleaning cycle.
  • Change solution frequently at least as often as manufacturer recommends.
  • Rinse instruments after ultrasonic cleaning with water to remove ultrasonic cleaning solution.

Sterilization should be performed in a medical grade instrument tray or disposable paper or plastic pouch. Sterilize in compliance with the local guidelines for hospital hygiene. Sterilization of instruments may be accomplished by Autoclave or Ethylene Oxide. Time and temperature parameters required for sterilization vary according to type of sterilizer, cycle design, and packaging material.

Autoclave Sterilization

  • Do not sterilize instruments at temperatures over 141°C (285°F).
  • All ring handled instruments must be autoclaved in the fully open position to prevent cracking of the box lock.
  • All instruments must be sterilized in the completely open and disassembled (i.e. taken-apart) configuration. Note that applicable instrument disassembly should not require any mechanical tooling (i.e. screwdriver, pliers etc.).
  • All devices shall be positioned to allow steam contact of all surfaces.
  • Always verify parameters with sterilizer manufacturer’s written instructions.
  • The use of “flash” sterilization is not recommended, as it may shorten the life of instruments.
