How to Clean Surgical Instruments Ultrasonically?

Cleaning and sterilization of surgical instruments with the ultrasonic machine are much easier, simpler and efficient than normal manual cleaning process. It s therefore highly recommended.

The Sonic cleaners meant for cleaning surgical instruments use an intense yet gentle process known as cavitation that scrubs away all contaminants from the surface of the instrument placed in the cleaning tank of an ultrasonic cleaner.

Here are the quick steps which help in knowing about how the process is accomplished safely.

  • The surgical and medical instruments having removable parts should be disassembled before you begin with the cleaning procedure.
  • For cleaning the items, place all light-weighted instruments like scissors and microsurgery instruments on the top rack of ultrasonic cleaner device. Surgical instruments that are heavy should be kept in a separate tray.
  • Keep sharp instruments that are used regularly separate from non-sharp instruments while washing as sharp instruments are quite dangerous to handle and can easily harm anyone if not handled in a proper way.
  • Now, wash instruments in ultrasonic cleaner as per the directions provided in the instructions manual. Then rinse the surgical instruments in warm water. Allow the instruments to dry thoroughly after the thorough cleansing process.

The ultrasonic cleaning device is undoubtedly an ideal cleaning machine that can be utilized for cleaning the surgical instruments that require high precision cleaning on each and every surface or area.

However, if you want a much higher level of disinfection and sterilization in a research facility, there are advanced treatment methods like using autoclave and chemical sterilants (such as ethylene gas, hydrogen peroxide gas plasma, etc.).

Care that you read the steps, time settings, and other details provided with your specific ultrasonic cleaning machine before you use them for the very first time.

Is Cleaning and Sterilizing Same?

No, cleaning generally refers to washing the equipment to remove the dirt and grime. Whereas sterilisation is a term that refers to a process that kills the living agents like viruses, bacteria, fungi and spore forms.

Sterilisation is usually achieved by applying chemicals, heat, high pressure, and few other methods.

Can You Disinfect Surgical Instruments by Heating?

Yes, heating is one of the best ways of sterilizing biological instruments. The method is generally divided into two (dry heat and moist heat).

While dry heat method is most suited for metal instruments (that are prone to get corroded with moisture), moist heat is mostly used for sterilizing the instruments made of fabrics, plastics, rubber or glass.

How to Sterilize Surgical Instruments Without an Autoclave?

Using an autoclave is the only method by which you can sterilize your instruments perfectly, there are methods like ultrasonic that can help in cleaning the instruments. Although not as great as autoclave, its much better than washing the instruments manually.

How to Clean The Greasy Surgical Instruments Manually?

Instruments used in surgery and dental procedures get heavily contaminated with saliva, blood or tissues and hence need to be thoroughly cleaned manually before the detailed sterilization process.

The process is important to accomplish for lab technicians or assistants so that the instruments can be reused without any risk for patients.

Some of the basic steps involved in this manual process of cleaning the medical parts are:

  • After use, rinse surgical instruments under warm running water (avoid hot water) to get rid of all the deposited liquids and tissue.
  • Use a stiff nylon brush to clean the instrument using a neutral pH7 detergent – brush up every instrument thoroughly until their surface gets fully cleaned.
  • Before cleaning, make sure blades and hinged instruments are interlocked properly. If you are cleaning suction tubes, check that their interiors are also clean.
  • Finally, rinse surgical instruments under warm running water again until they become detergent free and clean.
  • While washing scissors or any hinged instrument, check them carefully by opening and closing them till they become totally cleaned.
  • Now leave instruments under open-air (to dry naturally) in the clean area which is free of moisture.

These are the basic steps that help in cleaning the surgical instruments in Hospitals and labs efficiently and safely.

For those who are employed in cleaning the surgical instruments, it is recommended to take the professional advice from the manufacturers or to read the instruction manuals carefully before employing the particular methods for cleaning the instruments.

This will lower down all the risks and help in cleaning of the instruments safely and risk-free.
