Quick Reference for Sterilization of Sapphire Knife

序章
After a good cleaning and disinfection, your surgical instruments may be sterilized using a variety of methods. The chart below shows two common methods, autoclaving and cold sterilization. Sterilization destroys all microbial life. Some chemical sterilants can be used as high level disinfectants when used for shorter exposure periods

Cleaning

Manual Cleaning

  1. Use a syringe with distilled water to flush the instrument of blood and body fluids.
  2. Dip the blade and handle into a weak alkaline cleaning solution and let it sit for 60 minutes at a temperature of +22°C (+72°F ).
  3. The handle of a knife may be cleaned with a soft brush.
  4. Flush the instrument with tap water for 30 seconds. Then, rinse with distilled water for other 30 seconds. The blade should be pointed down for flushing.

Ultrasonic Cleaning

Using a  sterilizing case with silicon inserts or mats to reduce vibration and protect the blade.

  1. Fill the ultrasonic cleaner with warm distilled water (+70°C (+152°F)).
  2. Immerse the blade and handle in the water.
  3. A 2 to 3 min washing cycle should be enough to clean knife.
  4. Rinse the instrument with distilled water. 

    Suggested Sterilization Methods

    We recommend sterilizing the knives in trays with silicone inserts or silicone mats. This will prevent movement.

    These sterilization cycles represent the industry standards and should be capable of producing a sterile device.

    NOTE: Ethylene oxide (ETO) sterilization is recommended for items that are heat or moisture sensitive, and is best  suited for expensive medical equipment. ETO takes longer, between 3.5–16 hours to ensure sterilization. If time is not an factor, then ETO is an excellent sterilization method. Follow the manufacturer's recommendation for your instruments.
