instrument milk
A lubricating solution applied to surgical instruments after cleaning to maintain joint movement and prevent corrosion during sterilization.
Full Definition
Instrument milk is a water-soluble, biocompatible lubricating solution specifically formulated for surgical instruments. Applied after cleaning and before sterilization, it penetrates instrument joints and mechanisms to maintain smooth operation and protect against corrosion and mineral deposits. The solution must be steam-penetrable and leave no residue that could interfere with sterilization or cause patient reactions. Different formulations are available for specific instrument types and sterilization methods. Proper application involves complete immersion or spray coverage, followed by drainage before packaging. Regular use of instrument milk significantly extends instrument life and maintains optimal function.
Usage
Usage note: Never hyphenated; the term 'milk' refers to the solution's appearance, not dairy content.
