Diamond Knife Care and Cleaning

CAUTION: Extreme care must be used when handling the DGH-KOI surgical diamond knife, as the diamond blade can be damaged when handled improperly. It is recommended that the diamond blade be retracted when the knife is not in use. When cleaning, never apply excessive side to side motion to the diamond.

NOTE: It is very important that cleaning of DGH-KOI surgical diamond knife be done immediately following surgery to prevent subsequent debris build up, which can cause damage to the knife.

The following steps are recommended by DGH-KOI to clean the Surgical Diamond Knife after surgery:

• Immediately following surgery, fill two containers, one with Hydrogen Peroxide, the other with distilled water. Extend the blade and swig the top 1/4 of the knife in Hydrogen Peroxide for approximately (2) minutes. Shake off excess moisture and repeat the same procedure in distilled water.
• Inspect the blade under magnification. If the blade Is clean, autoclave as normal. If debris Is present, extend blade and hold top 1/4 of knife in an ultrasonic cleaning unit containing distilled water and an Enzyme tablet for approximately 2-3 minutes. Shake off excess moisture and inspect the blade.
• Autoclaving at 275°F maximum temperature for 3 to 5 minutes is the recommended sterilization method for DGH-KOI Surgical Diamond Knives and Coin gauges. The blade must be in the retracted position during sterilization. 
• DGH-KOI surgical diamond knives must be dried thoroughly before storage.
