The cleaning and disinfection process for minimally invasive surgical instruments usually includes the following steps:
Pretreatment: Temporarily store the used surgical instruments in a special container for subsequent cleaning. Before storage, you can rinse the visible dirt on the surface of the instrument with running water.
Disassembly and soaking: First disassemble the accessories to wash away the blood, then soak them in an appropriate enzyme solution for 5 minutes, and then rinse them with running water. Pay attention to avoid losing small accessories. You can also use an ultrasonic cleaner or an automatic cleaning and sterilization machine for cleaning.
Classification and grouping: Classify surgical instruments of different materials and shapes for subsequent cleaning.
Cleaning: Includes steps such as flushing, washing, rinsing and terminal rinsing. For precision instruments, follow the instructions for use or instruction manual provided by the manufacturer.
Disinfection: The cleaned instruments need to be disinfected. Common disinfection methods include high-pressure steam sterilization, chemical disinfection (such as alcohol disinfection, peracetic acid disinfection), ethylene oxide fumigation, etc.
Drying: After disinfection, the instrument needs to be dried to ensure that there is no moisture left.
Inspection and packaging: The instrument is inspected to ensure that it functions properly and is properly packaged for storage and use.
Sterilization: The last step is sterilization to ensure that the instrument is sterile. Commonly used sterilization methods include pressure steam sterilization, ethylene oxide sterilization, medical endoscope sterilization, and plasma sterilization.
The entire process needs to be carried out strictly in accordance with standard operating procedures to ensure the safety and effectiveness of surgical instruments.
The pretreatment steps of minimally invasive surgical instruments specifically include the following operations:
Flowing water pre-rinsing: First, use flowing water to preliminarily rinse the instrument to remove dirt and residues on the surface.
Enzyme solution soaking: Soak the instrument in enzyme solution to decompose organic contaminants such as blood, protein, etc.
Brush and water gun scrubbing: Use a brush and water gun to carefully scrub each part of the instrument to ensure thorough cleaning.
Flowing water rinse: Rinse the instrument with flowing water again to remove residual enzyme liquid and dirt.
Ultrasonic cleaning machine plus enzyme cleaning: Use ultrasonic cleaning machine combined with enzyme liquid to deeply clean the instrument to further improve the cleaning effect.
Boiling disinfection: Boil the cleaned instrument to kill bacteria and viruses.
Purified water rinse: Rinse the instrument with purified water to ensure that there are no residual chemicals.
Lubrication: Apply an appropriate amount of lubricant on the surface of the instrument to prevent the instrument from rusting and sticking.
Drying: Finally, dry the instrument to ensure that it is dry and sterile.
The following steps and precautions need to be followed to correctly select and use ultrasonic cleaning machine or automatic cleaning and sterilization machine for minimally invasive surgical instruments:
Choose the right cleaning equipment:
Choose an ultrasonic cleaning machine with high frequency and stability to ensure the cleaning effect.
Make sure the cleaning machine can handle the size and shape of minimally invasive surgical instruments and can use water-based solutions for cleaning.
Prepare items for cleaning:
Place the minimally invasive surgical instruments to be cleaned in the cleaning basket, taking care not to exceed the maximum capacity of the cleaning tank.
Make sure the sample is placed on the cleaning basket to avoid direct contact with the bottom of the cleaning tank.
Add cleaning solution:
Choose the appropriate cleaning solution based on the material and degree of stains of the instrument. Different objects require different cleaning solutions, so make sure you use the right cleaning solution.
Fill the water tank with the appropriate cleaning solution, making sure it does not exceed the maximum fill line.
Start the cleaning machine:
Before starting the ultrasonic cleaning machine, close the lid of the cleaning machine (if any), and then start the ultrasonic cleaning machine.
The ultrasonic cleaning machine will automatically clean within the set cleaning time.
Operation precautions:
Confirm that the power socket is well grounded to prevent electric shock.
Regular maintenance and correct use are the key to extending the life and efficiency of the ultrasonic cleaning machine.
Follow the manufacturer's instructions and adjust the relevant parameters for optimal cleaning results.
Maintenance and troubleshooting:
Refer to the product operation manual for specific maintenance methods and troubleshooting solutions.
Regularly check the various parts of the cleaning machine to ensure their normal operation.
High-pressure steam sterilization
Specific operating procedures:
Preparation phase:
Place the sterilizer on an electric stove or gas stove with sufficient firepower, and add water to the pot until the water level mark line.
Confirm that the power supply is correctly connected, turn on the power switch on the right side of the sterilizer, and then press the "POWER ON/OFF" button to turn on the machine.
Loading phase:
Observe the water level and inject distilled water into the sterilizer.
Pack the items to be sterilized and put them into the sterilizer, leaving gaps between the items.
Close the door and seal:
After the items are loaded, confirm that the pressure in the pot is 0, gently press down the handle of the sterilizer cover, release the pedal of the foot cover lock, and open the cover.
Heating phase:
Close the exhaust valve and continue heating. At this time, because the steam cannot overflow, the pressure in the sterilizer is increased, thereby increasing the boiling point.
Cooling stage:
After sterilization, wait for natural cooling or use cooling water to lower the temperature, and remove the sterilized items after ensuring safety.
Notes:
If you find safety problems with the pressure cooker, you should report it to the safety manager in time, and it is strictly forbidden to handle it privately.
Use distilled water to avoid mineral deposition.
Make sure there is enough water in the sterilizer and keep the water level stable during operation.
Chemical disinfection method (such as alcohol disinfection, peracetic acid disinfection)
Alcohol disinfection:
Operation process:
Wipe the surface of the items to be disinfected clean.
Spray or wipe with medical alcohol (75%).
Make sure that the alcohol fully covers all areas that need to be disinfected.
Notes:
Alcohol is flammable and should be used away from fire and high temperature environments.
For some plastic products, alcohol may cause dissolution or discoloration, so use it with caution.
Peracetic acid disinfection:
Preparation process:
Add the required amount of acetic acid to the mixing container.
Slowly add hydrogen peroxide to the acetic acid while stirring continuously.
Adjust the pH value of the solution to between 3.5 and 4.5.
Precautions:
Peracetic acid is highly corrosive and irritating. Protective gloves and masks should be worn during operation.
Peracetic acid is unstable and needs to be stored and used in a light-proof and well-ventilated environment.
After use, thorough ventilation is required to avoid residual gas from causing harm to the human body.
Ethylene oxide fumigation
Specific operation process:
Preparation stage:
Ensure that the items to be sterilized are suitable for ethylene oxide fumigation. Items that are not suitable for sterilization by general methods can use ethylene oxide.
Loading stage:
Put the items to be sterilized in a special ethylene oxide fumigation bag and ensure that there is enough space in the bag for steam to penetrate.
Fumigation stage:
Put the fumigation bag containing the items in the fumigation cabinet, close the cabinet door and start the fumigation program.
Adjust the fumigation time and concentration according to the specific situation.
Post-processing stage:
After the fumigation is completed, open the cabinet door, take out the fumigation bag and place it in a well-ventilated place for exhaust.
The exhaust time is generally more than 24 hours to ensure that all residual gases are completely exhausted.
Precautions:
Ethylene oxide liquid itself is a good organic solvent that can dissolve some plastics, so it should be paid attention to during the disinfection process.
The vapor pressure of ethylene oxide is relatively large, so it has strong penetration into the sterilized items, and its diffusion can penetrate the micropores to achieve a thorough disinfection effect.
During the drying process of minimally invasive surgical instruments, the following details should be paid attention to to ensure that there is no residual moisture:
Confirm whether the instrument is completely dry: Before storage, it must be ensured that the instrument is completely dry, and avoid storing it in a humid place.
Check for instrument defects: During the drying process, the instrument should be carefully checked for defects such as damage, deformation or corrosion. If necessary, assemble the instrument before drying.
Vacuum control during sterilization: During the sterilization process, the size of the pre-vacuum directly affects the amount of residual air, and the residual air directly affects the EO gas, heat and moisture reaching the inside of the sterilized items. Therefore, it is very important to ensure that the vacuum degree meets the requirements before humidification.
Avoid using instruments with poor moisture resistance: For those medical devices that are sensitive to moisture, special attention should be paid to humidity control during the drying process to prevent moisture from remaining.
The efficiency comparison of pressure steam sterilization, ethylene oxide sterilization, medical endoscope sterilization and plasma sterilization is as follows:
Pressure steam sterilization:
Pressure steam sterilization is an efficient and reliable sterilization method, especially when using a pulsating vacuum pressure steam sterilizer, its sterilization effect is better than other methods. Cassette pressure steam sterilizers can complete the sterilization process in a shorter time, usually between 15-30 minutes, depending on the type and size of the instrument.
Ethylene oxide sterilization:
Ethylene oxide sterilizers have the ability to sterilize efficiently and can complete the sterilization process in a shorter time, improving work efficiency. Lin Liming's research shows that the sterility test pass rate of ethylene oxide sterilization is 100%, and no bacterial contamination occurs. In addition, increasing the concentration of ethylene oxide can improve sterilization efficiency, but too high a concentration will increase costs.
Medical endoscope sterilization:
The specific efficiency data for medical endoscope sterilization is not directly mentioned in the evidence, so a detailed comparison cannot be made.
Plasma sterilization:
The cycle time of the hydrogen peroxide low-temperature plasma sterilizer is 56.1 minutes, while the cycle time of the ethylene oxide sterilizer is 393.6 minutes, showing that plasma sterilization has a clear advantage in cycle time.
Both pressure steam sterilization and ethylene oxide sterilization are efficient sterilization methods, but ethylene oxide sterilization has certain advantages in ease of operation and automation. Plasma sterilization performs better in cycle time and is suitable for situations that require rapid processing.
