FAQ
The disinfection methods for laparoscopic surgical instruments mainly include the following:
High-pressure steam sterilization: suitable for high-temperature resistant surgical instruments, such as scalpels, forceps, etc. This method kills all microorganisms through high-temperature steam, and the effect is accurate and fast.
Ethylene oxide sterilization: suitable for instruments that cannot be sterilized with high-pressure steam, such as endoscope lenses, cameras, light source wires, etc. Ethylene oxide has strong bactericidal and penetrating power and will not damage the instrument materials.
Hydrogen peroxide plasma low-temperature sterilization: suitable for various types of laparoscopic instruments. This method has the advantages of accurate sterilization effect, rapidity, safety, environmental protection, and less stimulation to medical staff.
Solution immersion sterilization: Soaking with 2% glutaraldehyde or other disinfectants is one of the most commonly used disinfection methods. This method is suitable for most laparoscopic instruments, but attention should be paid to the concentration and action time of the disinfectant.
Gas fumigation sterilization: suitable for instruments that cannot be sterilized by high pressure and solution immersion, such as optical cables, ultrasonic knife handles, electric knife wires, laparoscopic lenses, etc. The main methods are ethylene oxide sterilization and formaldehyde fumigation sterilization.
Enzyme cleaning: After the operation, immediately soak the laparoscopic instruments in a 1:300 neutral multi-enzyme cleaner for 10 minutes. Enzymes can quickly decompose proteins and organic matter, so that residual blood, organic matter, mucus, etc. will not coagulate and adsorb on the instruments, making them easy to clean.
Ultrasonic vibration: After enzyme cleaning, ultrasonic vibration can be used to further clean the instruments to remove residual dirt and bacteria.
These methods have their own characteristics and scope of application. Choosing a suitable disinfection method can ensure the sterility of laparoscopic surgical instruments and ensure the safety of surgery.
The specific operating steps and precautions for high-pressure steam sterilization are as follows:
Specific operating steps:
Preparation stage:
Put the items to be sterilized in the high-pressure steam sterilizer to ensure that there is no obvious dirt or obstacles on the surface of the items.
Take out the inner sterilization barrel, and then add an appropriate amount of water to the outer pot so that the water surface is level with the triangular shelf.
Loading stage:
Wrap the culture medium and empty glassware to be sterilized with kraft paper and put them into the inner layer of the pot. Do not place too many items or overcrowd them. Leave one-third of the space in the pot.
The packages of items to be sterilized should not be too large (each less than 50cm×30cm×30cm) or too tight. There should be gaps between the packages to facilitate steam circulation.
Heating stage:
Add a cover and tighten the cover to ensure that there is no air leakage.
Add water to the pot until the water level mark line, then close the exhaust valve and continue heating to make the water in the sterilizer jacket boil and generate steam.
Sterilization stage:
During the sterilization process, pay attention to exhausting the cold air in the pot. If the cold air in the pot is not exhausted, it will affect the sterilization effect and fail to achieve the purpose of thorough sterilization.
When using superheated steam with a temperature of up to 120℃ and two atmospheres for sterilization, it must be operated strictly in accordance with the operating procedures, otherwise accidents are likely to occur.
Ending stage:
After sterilization, turn off the steam generator and wait for the pressure and temperature in the sterilizer to drop to a safe level.
Open the sterilizer door and take out the sterilized items. Be careful to use protective gloves to avoid burns.
Precautions:
During sterilization, the cold air in the sterilizer and the item package must be exhausted. If it is not completely exhausted, it will affect the sterilization effect.
The item package to be sterilized should not be too large or too tight. There should be gaps between each package to facilitate steam circulation.
Cloth items should be placed on metal items, otherwise the steam will condense into water droplets when it is cold, making the package damp, preventing steam from entering the center of the package, and seriously affecting the sterilization effect.
There are many studies and cases that have been discussed in detail on the scope of application and effect evaluation of ethylene oxide sterilization in laparoscopic surgical instruments.
Ethylene oxide sterilization is widely used in the disinfection of laparoscopic surgical instruments. Its main advantage is that it has a strong penetrating ability and can effectively sterilize items that are not resistant to moisture and heat. In addition, ethylene oxide sterilization basically does not damage laparoscopic surgical instruments, which makes it very reliable in practical applications.
In specific studies, there are detailed analyses of the effects of different sterilization methods. For example, one study compared the sterilization effect, cost and safety of laparoscopic instruments using three methods: pressure steam sterilization, low-temperature plasma sterilization and ethylene oxide sterilization. These studies show that ethylene oxide sterilization has certain advantages over other methods in terms of sterilization effect, but cost and safety factors also need to be considered.
In addition, there are studies that point out that ethylene oxide sterilization needs to pay attention to the problem of residual toxicity during use. For example, a study on a laparoscopic single-port surgical system provided research data on the residual toxicity of products after ethylene oxide and glutaraldehyde sterilization. This shows that when using ethylene oxide sterilization, its use conditions need to be strictly controlled to ensure the safety of the final product.
Hydrogen peroxide plasma low-temperature sterilization technology has many advantages over traditional disinfection methods. First, the technology can quickly kill all kinds of bacteria, viruses and fungi at low temperatures, effectively ensuring the sterility of medical devices, which is especially important for heat-sensitive and moisture-sensitive items. Secondly, hydrogen peroxide plasma sterilization has the advantages of short sterilization cycle time and low toxicity of the final product after thorough decomposition, which helps to improve the ability of operating rooms and supply rooms to handle emergency surgical instrument needs, reduce the difficulty of surgical instrument management, and improve the efficiency of operating rooms and the level of cooperation with clinical departments. In addition, the technology also has the characteristics of strong antibacterial and high stability, which can make up for the shortcomings of other sterilization methods.
However, hydrogen peroxide plasma low-temperature sterilization technology also has some limitations. First, the sterilization process takes a certain amount of time, usually several hours to complete, which may affect the rapid response in emergency situations. Secondly, the equipment and operation costs are high, and the skills of operators and the maintenance requirements of equipment are also strict. In addition, since cloth and paper packaging materials can absorb H2O2 sterilants, paper and cotton packaging materials cannot be used; there must not be any items containing wood pulp and items made of cellulose-containing materials, such as paper or cardboard, gauze, sponges, wood, linen, linen towels, etc. in the sterilized items, which limits the use of this technology in certain application scenarios.
In solution immersion sterilization, the selection criteria and concentrations of 2% glutaraldehyde and other disinfectants have a significant impact on the disinfection effect. First, 2% glutaraldehyde solution is usually used for immersion disinfection and sterilization of medical devices, and its effective immersion time is about 10 hours, but the specific time should be appropriately adjusted according to the type and size of the device to ensure an effective sterilization effect. In addition, the glutaraldehyde solution is replaced every 1-2 weeks, and the concentration is monitored weekly within the effective concentration to maintain its disinfection effect.
For other disinfectants, such as ethanol and formaldehyde, their bactericidal effect is closely related to concentration and action time. For example, the bactericidal effect of ethanol solution will be reduced due to excessively high or low concentration. Formaldehyde solution is recommended to be immersed for 30 minutes, which is suitable for the disinfection of materials such as plastics and plexiglass.
Overall, choosing the right disinfectant and its concentration is the key to ensuring the disinfection effect.
Evaluation of the efficiency and safety of ultrasonic oscillation technology in removing dirt and bacteria from the surface of laparoscopic surgical instruments.
Ultrasonic oscillation technology has significant efficiency and safety in removing dirt and bacteria from the surface of laparoscopic surgical instruments. Ultrasonic cleaning technology can effectively remove visible dirt, reduce the bioburden on surgical instruments, and remove bacterial endotoxins, thereby improving the success rate of sterilization. In addition, ultrasonic cleaning machines use high-frequency sound waves to generate tiny bubbles, which can stir the cleaning solution and penetrate the smallest gaps of surgical instruments to effectively remove dirt, blood and other contaminants on the surface of the instruments.
Ultrasonic cleaning is not only fast and efficient, but also environmentally friendly because it uses less water resources than traditional cleaning methods. However, despite the many advantages of ultrasonic cleaning, it is still necessary to pay attention to choosing the right frequency during use to avoid possible adverse effects. For example, ultrasonic cleaners of different frequencies have different cleaning effects on laparoscopic surgical instruments, so professional nurses are needed to select the appropriate frequency according to the specific situation to ensure cleaning quality while avoiding adverse effects.
