How to Clean, Sterilize, and Maintain Surgical Instruments?

10 Methods to Clean and Sterilize Surgical Instruments

Attentive handling, cleaning, and thorough sterilization of surgical instruments are essential to maintain their accuracy, longevity, and functionality. The surgical instruments manufactured by Rahmet Group are designed to meet the highest quality standards. Adherence to the recommended handling and maintenance practices ensures a long service life, consistent reliability, and the preservation of patient safety in medical practice.

1. Main Handling Guidelines

Proper handling of surgical instruments is essential to maintain their accuracy, durability, and efficiency. Follow these guidelines to ensure instruments remain in optimal condition.

  • The product must be handled with a lot of care in order to prevent any harm or exposure to any chemical substance.

  • Use instruments with care not to drop, hit or abuse them and lose accuracy.

  • Apply every tool to the purpose it is supposed to serve. This cushions the sensitive sections and maintains the instruments at their maximum efficiency.

  • Distinct fine and accuracy tools with heavier ones. This eliminates bending, scratching or misalignment.

  • Do not exert any unneeded force or twisting to hinged tools including scissors, forceps, or needle holders.

  • Carrying tools in safes or boxes. This avoids hitting and makes them well organised.

2. Pre-Cleaning

Proper pre-cleaning ensures instruments remain in good condition and prevents damage.

  • Wash instruments immediately after use to get rid of blood, tissue, and other contaminants.

  • Always keep tools wet so they do not leave behind any dried residue that will cause surface damage or corrosion.

  • Open and disassemble equipment where feasible (e.g., scissors, retractors, box-locks) to allow cleaning of all surfaces.

  • Different metals should not be mixed, i.e., stainless steel with plated or ebonized tools, as they will react or scratch.

  • Cleanse off any conspicuous dirt with soft brushing or running water before beginning the actual cleaning process.

3. Cleaning Precautions

Following proper cleaning precautions protects instruments.

  • Instruments should not be left in hot water, alcohol, disinfectants, or antiseptics over a long period, as this may lead to corrosion or damage the coating.

  • Wire brushes, steel wool, pipe cleaners, or abrasive detergents should be avoided, as they can scratch or weaken the surface.

  • Delicate and microsurgical instruments must be hand cleaned, not in ultrasonic cleaners, to protect fine tips, edges, and coatings.

  • Wash daily and apply only pH-neutral detergent to maintain instrument integrity.

  • Avoid exposing instruments to acidic or alkaline solutions over a long period to prevent pitting and surface damage.

  • Wash all tools carefully to maintain sharpness and orientation.

4. Manual Cleaning

Manual cleaning ensures thorough removal of contaminants, especially for delicate instruments.

  • Wipe clean instruments immediately after use to avoid biofilm formation and bacterial growth.

  • Clean with soft brushes, water spray guns, or lint-free cloths, focusing on hinges, ratchets, and serrations.

  • Wash with lukewarm distilled or demineralized water to remove traces of detergent.

  • Ensure all joints and moving parts are clear so they operate smoothly.

  • For delicate instruments, use special cleaning kits or tools prescribed by the manufacturer.

  • Inspect instruments during the cleaning process for damage, staining, or corrosion.

5. Ultrasonic Cleaning

Ultrasonic cleaning is effective for intricate instruments and hard-to-reach areas.

  • Intricate instruments such as box-locks, serrated forceps, and fine tips can be cleaned using ultrasonic cleaning.

  • Wipe all instruments with a towel before placing them in the ultrasonic bath; large particles may scratch surfaces.

  • Use a low-sudsing, neutral pH detergent and follow manufacturer-recommended times, temperature, and agitation.

  • Store sharp tools apart to prevent contact, blunting, or damage.

  • Avoid combining different types of metals (e.g., stainless steel with copper or aluminum) in the same cleaning cycle to prevent corrosion.

  • Open hinged instruments to allow ultrasonic waves to reach all internal surfaces.

  • Wash instruments thoroughly after ultrasonic cleaning to remove residual detergent before drying or sterilization.

  • Inspect instruments after cleaning for stains, discoloration, or mechanical problems, and ensure all moving parts operate smoothly.

6. Rinsing and Drying

Corrosion is avoided by proper rinsing and drying, and instruments are ready to be sterilized.

  • Clean with distilled, pyrogen-free water after cleaning to get rid of all traces of detergent.

  • Wipe dry with a soft lint-free cloth, air-dry, or use compressed air to remove all moisture.

  • Make sure that hinges, joints, and serrations are dry so that they do not rust or corrode.

  • Do not pile wet instruments, as the moisture that gets trapped may result in staining or pitting.

  • Have protective drying trays available to permit air circulation around delicate instruments.

7. Lubrication

Lubrication is necessary to ensure the smoothness and durability of hinged and movable instruments.

  • Rub all joints, hinges, and moving parts with medical-grade sterilizable lubricant.

  • Lubricate after cleaning, particularly after ultrasonic cycles, before sterilization.

  • Never rinse instruments after lubrication, as it removes the protective layer.

  • Use minimal lubricant to avoid buildup and debris accumulation.

  • For precision tools, ensure the lubricant reaches all moving parts and does not contact cutting edges.

8. Sterilization

Sterilization ensures infection control and the safety of instruments.

  • Autoclaving with steam from distilled water is an effective way of sterilizing instruments.

  • Do not stack too many instruments on autoclave trays, ensuring all instruments are penetrated by steam.

  • Ensure instruments are free from detergent residues, which can cause corrosion and staining.

  • Place instruments in autoclave-approved trays or rigid containers to maintain sterility until use.

  • Follow manufacturer guidelines for sterilization temperature and exposure time; never lower exposure below the recommended minimum.

  • Separate fine, sharp, and heat-sensitive tools to prevent damage during sterilization.

  • Verify sterilization effectiveness using indicator tapes or chemical indicators.

9. Inspection and Storage

Regular inspection and proper storage maintain the quality and safety of instruments.

  • Check instruments for damage, wear, or staining prior to and after sterilization.

  • Test the movement of parts, ratchets, and cutting edges to ensure they operate smoothly.

  • Discard or replace faulty tools to avoid risk during surgical procedures.

  • Store instruments in a clean, dry, and well-ventilated environment to prevent corrosion and contamination.

  • Protect delicate tips with silicone or plastic covers to prevent bending or dullness.

  • Use shelves or trays that are easy to clean and allow air circulation.

  • Organize instruments by type and size for quick access and reduced handling damage.

  • Do not stack instruments to avoid scratches or mechanical damage.

10. Routine Maintenance

Routine professional maintenance ensures long-term performance and reliability.

  • Schedule professional sharpening, alignment, and calibration of precision instruments regularly.

  • Do not store uncleaned instruments for long periods, which can cause corrosion or staining.

  • Follow Rahmet Group instructions for instrument care to ensure long life and safe use.

  • Maintain a record of all instruments, documenting cleaning, lubrication, and servicing history.

  • Train personnel on the proper handling, cleaning, and storage of instruments to maintain high standards.
