Key Takeaways

  • Disassembling medical instruments is a key step in the cleaning process.
  • Identifying instruments that require disassembly and using appropriate methods for their cleaning are essential steps to maintain instrument integrity.
  • Training and compliance are necessary to ensure safety, knowledge, skills, and regulatory standards when disassembling & cleaning medical instruments.

The Importance of Disassembling Medical Instruments for Cleaning

Proper instrument cleaning is paramount for patient safety and preserving the functionality of medical devices. A thorough cleaning process helps prevent the transmission of pathogens to patients and reduces the risk of damage to the device’s surfaces or functionality, which can affect the sterilization process. Quality control in instrument cleaning plays an essential role in ensuring satisfactory results for patients.

Medical instruments can be cleaned using various methods, including manual cleaning, ultrasonic cleaning, and washer/disinfector cleaning. Each cleaning method has its own set of advantages and challenges in reaching hard-to-reach areas and effectively cleaning complex instruments. For instance, ultrasonic cleaners use high-frequency sonic waves to generate microscopic bubbles that implode on contact with the instrument’s surface, creating a cavitation process that removes contaminants from even the hardest-to-reach areas. On the other hand, washer/disinfectors use spray arms and pressurized water with cleaning solutions to clean and disinfect instruments.

Regardless of the cleaning method used, adherence to the manufacturer’s instructions and established cleaning procedures is vital. This practice doesn’t only ensure the effectiveness of cleaning and sterilization of medical equipment but also extends the lifespan of these instruments.

Identifying Instruments That Require Disassembly

Determining which medical instruments require disassembly is a vital step towards proper cleaning. Complex instruments like power tools, and items with lumens, crevices, and articulating arms often necessitate disassembly for a comprehensive cleaning. Prior to high-level disinfection and sterilization, a meticulous cleaning process is necessary to remove any contaminants from these hard-to-reach areas.

Adhering to the device’s individual Instructions for Use (IFUs) is crucial to ensure proper reprocessing of medical equipment in accordance with the manufacturer’s guidelines. For example, stainless steel instruments are best sterilized using an autoclave or steam sterilization cycle, but always consult the manufacturer’s IFU for specific recommendations.

When using washer/disinfectors with spray arm technology, consider factors such as water temperature, chemical concentration, flow rate, and device loading to ensure successful cleaning. The suggested temperature range for utilizing cleaning solutions in washer/disinfectors is between 122-180 F/50-82 C, although this may vary depending on the manufacturer.

Step-by-Step Guide to Disassembling Medical Instruments

Initiating a pre-treatment of the surgical instrument using enzymatic cleaning chemistries is a crucial step before starting the disassembly process. This helps break down contaminants and prepares the instrument for the next steps in the cleaning process.

During disassembly, be gentle and careful to avoid causing damage to the instrument. Wearing an anti-static wrist strap can help prevent damage from static electricity, ensuring that the instrument remains in optimal condition throughout the cleaning process.

Once the instrument is disassembled, it should be disinfected both internally and externally using methods such as ultrasonic cleaners. This ensures that all components of the instrument are thoroughly cleaned and ready for reassembly and reuse.

Choosing the Right Cleaning Method for Disassembled Instruments

Once disassembled, the next step is to choose the most appropriate cleaning method for your medical instruments. There are three primary methods of sanitizing clean surgical instruments: manual cleaning, washer/disinfector cleaning, and ultrasonic cleaning. Each method has its own advantages and challenges, making it crucial to choose the right one based on the specific instrument and its complexity.

Manual cleaning is employed when machine cleaning is not feasible or when instruments have complex structures that require more targeted cleaning. Ultrasonic cleaning systems, such as an ultrasonic cleaner, use high-frequency sonic waves to generate microscopic bubbles that implode on contact with the instrument’s surface, providing effective cleaning for even the hardest-to-reach areas. Washer/disinfector cleaning is an automated process that utilizes water, detergent, and heat to effectively cleanse and disinfect instruments.

When choosing a cleaning method, consider factors such as the instrument’s material, complexity, and the manufacturer’s guidelines. By selecting the most appropriate cleaning method, you’ll ensure that your disassembled instruments are properly cleaned and ready for reassembly and reuse.

Reassembling and Inspecting Cleaned Instruments

After cleaning your instruments, they should be reassembled following the manufacturer’s guidelines. This helps maintain the integrity and functionality of the instruments, ensuring that they’re ready for use in patient care.

After reassembling the instruments, perform a visual inspection with a lighted magnifying glass to ensure thoroughness. Inspect the instruments for cleanliness and dryness, checking for any signs of residual contamination or damage.

If necessary, apply a lubricant to the hinges and lockbox of the instruments as recommended by the manufacturer. This helps ensure smooth operation and prolongs the lifespan of the instruments.

Tips for Maintaining Medical Instruments

The maintenance of medical instruments extends beyond mere cleaning and sterilization. Training and retaining competent staff is crucial to ensure they remain knowledgeable and updated on the correct use and maintenance of these instruments.

Daily routine checks should be conducted to inspect instruments for any signs of wear and tear, damage, or contamination. Replace reagents and lubricants according to the manufacturer’s instructions to ensure optimal performance and longevity of the instruments.

Maintain a hygienic work environment by regularly cleaning and disinfecting the area, and ensure that all instruments are stored appropriately. This helps prevent contamination and promotes a safe, clean workspace for staff.

Training and Compliance for Instrument Disassembly and Cleaning

There are several reasons why training and compliance in instrument disassembly and cleaning are of utmost importance. Primarily, safety is of utmost importance; proper training ensures that individuals handling the instruments are aware of the potential hazards and risks associated with disassembly and cleaning, and compliance with safety protocols helps prevent accidents and injuries.

Additionally, training provides individuals with the knowledge and skills necessary to:

  • Disassemble and clean instruments correctly
  • Ensure compliance with established procedures
  • Thoroughly and effectively clean instruments
  • Reduce the risk of contamination or infection

Lastly, compliance with training requirements and established protocols ensures that healthcare facilities meet regulatory standards and guidelines set forth by agencies such as AAMI/ANSI, FDA, and AORN. This is particularly important in healthcare settings where cleanliness and infection control are critical.


Disassembling medical instruments for cleaning is a crucial process that ensures patient safety and prolongs the lifespan of the equipment. By following the comprehensive guide in this blog post, you’ll be well-equipped to maintain the cleanliness, safety, and longevity of your medical instruments, ultimately providing the best possible care for your patients.

Frequently Asked Questions

How and why are instruments disassembled for decontamination?

Instrument decontamination requires instruments composed of more than one piece to be disassembled, allowing the cleaning solution to access all surfaces to prevent organic material and debris from being retained.

How can I maintain the cleanliness and longevity of my medical instruments?

To ensure cleanliness and longevity of your medical instruments, conduct daily checks, replace reagents and lubricants as needed, and follow manufacturer instructions for cleaning, storage, and maintenance.
