Best Practices for Sterilizing Laboratory Forceps

Best Practices for Sterilizing Laboratory Forceps

When it comes to sterilizing lab forceps, it is crucial to follow proper protocols to maintain a sterile environment and prevent cross-contamination. Like other surgical instruments, laboratory forceps may be sterilized by autoclaving, dry heat, or a chemical sterilant. However, forceps are uniquely designed for many specific functions, and a few pointers here can ensure you get the best results.

NOTE: Always follow the manufacturer's instructions and best practices to ensure effective sterilization and maintenance of your lab forceps.

Types of Sterilization

Autoclaving (steam sterilization) is a widely used and highly effective sterilization method, killing a broad range of microorganisms, including bacteria, viruses, and spores, ensuring high-level sterilization for surgical forceps. Most stainless steel and titanium surgical forceps can withstand the heat of autoclaving without significant damage or loss of functionality. Autoclaving offers relatively quick sterilization cycles, making it a top choice.

Dry heat sterilization provides an alternative method for sterilizing instruments without moisture or steam, minimizing the risk of damage. It is safer for heat-sensitive forceps. Since it does not introduce moisture, the chances of corrosion on forceps with delicate surfaces or coatings is dramatically reduced.

Chemical sterilization methods, such as ethylene oxide (ETO) gas or hydrogen peroxide plasma sterilization, are ideal for forceps that cannot withstand high temperatures or autoclaving. Because chemical sterilants can effectively reach the nooks and crannies, this method may be preferred for laboratory forceps with a complex design. Chemical sterilization methods are typically less harsh on materials, minimizing the risk of damage to delicate forceps.

Low-temperature sterilization methods, like hydrogen peroxide plasma, can be useful for lab forceps made from heat-sensitive materials, including plastics or certain coatings. Compared to some other low-temperature methods like ETO, hydrogen peroxide plasma sterilization offers shorter cycle times.

Proper Cleaning

Before sterilization, after every use, clean your lab forceps to remove any visible debris or organic matter. Use a suitable cleaning agent, such as a mild detergent (Alconox or UltraDose) or enzymatic cleaner (Enzol or Enozime), and rinse them thoroughly with running water. Use only neutral pH detergents. Low pH detergents may break down the stainless protective surface and cause black staining, if it is not properly rinsed. High pH detergents can cause surface deposits of brown stains, that can interfere with the smooth operation of your lab forceps.
Forceps are designed to provide a firm grip of tissues or objects during surgical procedures. They often have a tweezer-like design with two opposing blades or ring handles like scissors. The intricate design and small gaps between the serrated blades or teeth can make it challenging to ensure thorough cleaning and effective sterilization. When cleaning, pay special attention to the areas where the blades meet, box lock areas, ratchets, and hinges.

• Use stiff, plastic cleaning brushes for cleaning the serrated tips.
• Do not use steel wool or wire brushes.
• Use of micro cleaning brushes or swabs can help you get into tiny recesses in fine surgical instruments where debris gets stuck.

Inspecting Surgical Forceps

After cleaning your instruments, take a moment to inspect each one. Look for any damage, wear, or other issues that may affect their functionality or sterility. Here are some tips for inspecting forceps:

• A well-lit area or a light source such as a lamp can help you identify small cracks, discoloration, or other abnormalities.
• Look for any visible debris, residue, or organic matter. Look for signs of corrosion, rust, discoloration, or pitting on the surface of the forceps. Check the joints, handles, and tips for any signs of damage, such as cracks, chips, or bent areas.
• Gently open and close the forceps to check the functionality of the mechanism. Do you notice any stiffness, resistance, or misalignment during the operation? If there is any abnormality or difficulty in movement, it may indicate a problem that needs further attention.
• Ensure that the blades align properly and smoothly. In a closed position, hold the tips of the forceps up to the light to ensure that the teeth or serrations nest together properly. You should not see light between the blades.
• Pay particular attention to the hinge area where the forceps open and close. Inspect for any signs of wear, looseness, or misalignment.
• Hemostatic forceps should lock and unlock easily, and the joints should not be too loose. Excessive play in the hinge mechanism may affect the precision and reliability of the forceps.
• Clamp the forceps on a plastic surface. You should see a clear and consistent impression on the plastic when the forceps are removed.
• Ratchets should engage crisply and smoothly. When the ratchet is engaged, it should not open easily if the instrument is lightly tapped on the edge of a table.

If you encounter any significant damage, malfunction, or concerns during the inspection, it is probably time to replace your laboratory forceps.

Sterilization Protocol

After inspection of your forceps, select an appropriate method of sterilization. Autoclaving is the most common method of sterilization for surgical instruments. Lab forceps made of heat-sensitive materials or components may not be suitable for autoclaving, and dry heat sterilization can be an alternative. For delicate or heat-sensitive forceps, chemical sterilization methods may be appropriate. Follow the manufacturer's instructions for dry heat sterilization or chemical sterilants.
When autoclaving, place the clean forceps in a sterilization pouch or wrap them in autoclave paper. Properly seal the pouch or wrap. Wrapped instruments may be placed in sterilization baskets for easy handling. Load the sterilization baskets or wrapped forceps into the autoclave according to the manufacturer's instructions, and set the autoclave temperature, pressure, and time, based on the material of the forceps and any manufacturer guidelines. Then run the autoclave cycle.
After sterilization, it is crucial to handle the forceps properly to maintain their sterility. Store the sterilized forceps in a clean, dry environment, preferably in a covered container, a sterilization basket, or pouch until they are ready to be used. Now take a moment to document the sterilization processes, including the date, method, and any relevant parameters. This documentation helps track the sterilization history and ensures compliance with regulatory requirements.
