How to disinfect and sterilize minimally invasive orthopedic surgical instruments?

The disinfection and sterilization methods of minimally invasive orthopedic surgical instruments mainly include chemical disinfection and physical disinfection. Chemical disinfection usually uses chemical agents such as alcohol, peracetic acid, chlorhexidine, etc., which are suitable for temperature-sensitive instruments, but attention should be paid to the concentration and contact time of the agent to ensure the effect. Physical disinfection includes methods such as high-pressure steam sterilization, dry heat sterilization and ultraviolet sterilization. Among them, high-pressure steam sterilization is currently the most widely used method, which can kill various microorganisms in a short time and has low corrosion to the instrument.

Specifically for minimally invasive orthopedic surgical instruments, the following sterilization methods can be used:

High-pressure steam sterilization method: suitable for high-temperature resistant instruments and items. It can kill all microorganisms including spores by reaching a certain temperature and time through high-pressure steam.

Low-temperature sterilization method: mainly using low-temperature formaldehyde and hydrogen peroxide methods, suitable for the disinfection of medical devices that are not used for a long time.

Ethylene oxide gas method: suitable for medical devices that cannot withstand high temperatures, and alkylates with microbial proteins, DNA and RNA to cause the death of microorganisms.
Microwave sterilization: Use microwave heating to achieve all-round safe cleaning, disinfection and sterilization.
In addition, for special infection surgical instruments, such as instruments contaminated by prions, they should be soaked in 1mol/L sodium chloride solution for 60 minutes before pressure steam sterilization. Instruments contaminated by gas gangrene need to be soaked in 3% hydrogen peroxide or 0.2% peracetic acid or 2000~5000mg/L chlorine-containing disinfectant for 30-60 minutes, and then processed according to the general instrument processing process.

In short, the disinfection and sterilization of minimally invasive orthopedic surgical instruments should choose appropriate disinfection methods according to the specific materials and tolerance conditions of the instruments to ensure surgical safety and long-term use of the instruments.

What are the specific temperatures and times for minimally invasive orthopedic surgical instruments when using high-pressure steam sterilization?

When using high-pressure steam sterilization for minimally invasive orthopedic surgical instruments, the specific temperatures and times are as follows:

The sterilization temperature is usually set at 121.3℃.
The sterilization time is generally between 15 and 30 minutes.
These parameters ensure that high-pressure steam can effectively kill various microorganisms, including bacteria, viruses and fungi, thereby achieving a sterilization effect.

What is the applicability and effect of low-temperature formaldehyde and hydrogen peroxide disinfection methods on minimally invasive orthopedic surgical instruments of different materials?
Low-temperature formaldehyde and hydrogen peroxide disinfection methods have their own characteristics in terms of applicability and effect of minimally invasive orthopedic surgical instruments.

Low-temperature formaldehyde disinfection method
Scope of application: Low-temperature formaldehyde steam sterilization is suitable for diagnostic and treatment instruments that are not resistant to moisture and heat, such as electronic instruments, optical instruments, luminal instruments, metal instruments, glassware, synthetic materials, etc. In addition, it is also suitable for the disinfection of temperature-sensitive materials.
Sterilization principle: Medical devices are sterilized by using the bactericidal effect of formaldehyde gas combined with the temperature control of low-temperature steam. Formaldehyde gas has a broad-spectrum bactericidal effect and can kill various pathogenic microorganisms, including bacteria, fungi, viruses, etc.
Advantages: High-efficiency sterilization, can quickly kill various pathogenic microorganisms at low temperatures, and ensure the sterility of medical devices. No residue, suitable for instruments that need to be stored for a long time.
Application: Widely used in operating rooms, supply rooms, endoscopy rooms and other treatment rooms in medical institutions.
Hydrogen peroxide disinfection method
Scope of application: Hydrogen peroxide disinfectors are particularly suitable for environments with good killing effects on anaerobic Bacillus.
Sterilization principle: Hydrogen peroxide dissociates highly active hydroxyl groups through complex chemical reactions, destroying cell membranes, thereby achieving a sterilization effect.
Advantages: It has a strong redox effect and can effectively kill various pathogenic microorganisms, including anaerobic Bacillus.
Summary
Low-temperature formaldehyde disinfection is suitable for minimally invasive orthopedic surgical instruments of various materials, especially those that are not resistant to high temperature and humidity. Its advantages are efficient sterilization without residue, which is suitable for instruments that need to be stored for a long time. The hydrogen peroxide disinfection method is particularly suitable for environments that require good killing effects on anaerobic Bacillus, but it mainly targets specific types of pathogenic microorganisms.

Safety and environmental impact assessment of minimally invasive orthopedic surgical instruments disinfected by ethylene oxide gas.
Ethylene oxide (ETO) gas method has certain safety and environmental impact in sterilizing minimally invasive orthopedic surgical instruments, but its advantages and disadvantages need to be considered comprehensively.

Safety assessment
Ethylene oxide is a broad-spectrum, highly efficient gas sterilization disinfectant that can kill bacterial propagules, spores, viruses and fungi. The experimental results show that the items sterilized by ethylene oxide were tested for bacterial culture, and the bacterial culture was negative, which meets the requirements of complete sterilization.

After ethylene oxide sterilization, no ethylene oxide is left on the items, and it is safe to use. However, the sterilized items will release ethylene oxide gas during the ethylene oxide residue desorption process, causing pollution to the working environment. Therefore, it is necessary to ensure sufficient ventilation and desorption time to reduce the impact of residues.

Ethylene oxide itself is toxic and has a high vapor pressure. The exhaust gas emissions of sterilization facilities containing ethylene oxide that are not properly handled may cause environmental and health impacts. Workers operating sterilization facilities may be at risk of poisoning due to ethylene oxide leaking into the working environment or due to contact with medical supplies that are not fully ventilated after sterilization.

Environmental Impact Assessment
Ethylene oxide is a toxic gas that has a high adsorption capacity for many items and may produce harmful gas emissions during the sterilization process. Ethylene oxide in the medical disinfection industry is an environmental pollutant source that cannot be ignored, and the government and enterprises need to pay attention to and prevent it in a timely manner.

Government regulatory authorities should issue corresponding regulations and specifications for the emission and treatment of characteristic pollutants of ethylene oxide in the medical disinfection industry, and increase the supervision of waste gas treatment.

Conclusion
The ethylene oxide gas method has a good sterilization effect and a wide range of applications in the disinfection of minimally invasive orthopedic surgical instruments, especially for medical devices that are not resistant to high temperature and high humidity.

Research on the efficiency and safety of microwave sterilization technology in the disinfection of minimally invasive orthopedic surgical instruments.
The efficiency and safety of microwave sterilization technology in the disinfection of minimally invasive orthopedic surgical instruments can be analyzed from multiple perspectives.

From the perspective of efficiency, microwave sterilization has significant advantages. According to evidence, microwave sterilization has a short time and fast speed, and can quickly kill pathogenic microorganisms. In addition, the microwave sterilization process is efficient and energy-saving, and the equipment design is compact, which reduces the use of materials and production costs. These characteristics enable microwave sterilization to greatly shorten the disinfection time and improve work efficiency when handling surgical instruments.

From the perspective of safety, microwave sterilization technology also performs well. Microwave sterilization can effectively kill different types of microorganisms through the combined action of thermal and non-thermal effects. This technology is not only suitable for various environmental media, but also ensures the cleanliness and safety of the instrument while maintaining the physiological activity of the functional components of the instrument. In addition, microwave sterilization equipment usually has good controllability and automated production capabilities, which further improves its reliability and safety in practical applications.

However, despite the many advantages of microwave sterilization technology, there are still some problems that need to be improved during its application. For example, the uniformity and frequency selectivity of microwave radiation may affect the stability and reliability of the sterilization effect. Therefore, in practical applications, these technical details need to be continuously studied and optimized to ensure the efficiency and safety of microwave sterilization technology in the disinfection of minimally invasive orthopedic surgical instruments.
