What are the sterilization and disinfection methods of disposable radiofrequency ablation plasma knife (electrode)?
Release Time : 2025-02-26
As a medical device, the sterilization and disinfection of disposable radiofrequency ablation plasma knife (electrode) are of great significance for preventing cross infection and ensuring patient safety. Therefore, it must be ensured that it has undergone strict sterilization before surgery.
For disposable radiofrequency ablation plasma knife (electrode), commonly used sterilization methods include ethylene oxide sterilization and ionizing radiation sterilization (such as γ-ray sterilization). These methods can effectively kill microorganisms such as bacteria and viruses to ensure the sterility of the instrument.
Ethylene oxide sterilization is to fumigate the instrument with ethylene oxide gas to achieve the purpose of sterilization. The process requires strict control of temperature, humidity and ethylene oxide concentration to ensure the sterilization effect. After sterilization is completed, ventilation is required to remove residual ethylene oxide gas.
Ionizing radiation sterilization is to irradiate the instrument with γ rays released by radioactive isotopes to achieve the sterilization effect by destroying the DNA structure of microorganisms. This method has the advantages of fast sterilization speed, strong penetration, and no need for chemical reagents.
The sterilized disposable radiofrequency ablation plasma knife (electrode) needs to be stored under sterile conditions to prevent secondary contamination during storage. At the same time, attention should be paid to the temperature and humidity of the storage environment to ensure the long-term preservation of the device.
It should be made clear that disinfection and sterilization are two different concepts. Disinfection refers to the process of killing or removing most pathogenic microorganisms on medical devices, while sterilization is the process of killing or removing all microorganisms on medical devices. For disposable radiofrequency ablation plasma knife (electrode), it is necessary to meet the sterilization standards.
When performing sterilization operations, the sterilization instructions provided by the manufacturer should be strictly followed to avoid over-sterilization or under-sterilization. At the same time, operators need to wear protective equipment to ensure their own safety.
