In minimally invasive surgery, especially in the use of laparoscopy, it has been crucially integral to sterilizing the surgical tools to prevent infection in a patient undergoing surgery. The ETO sterilizer for laparoscopy plays a vital role in achieving high-level sterilization, particularly on heat-sensitive medical devices that cannot stand the conditions accompanying the use of the ETO sterilizer, such as high temperature and moisture.
What is an ETO Sterilizer?
An ETO sterilizer is an instrument based on the principle of using ethylene oxide gas to sterilize materials or instruments. Colorless and odorless, ethylene oxide has powerful antimicrobial properties, so it kills bacteria, viruses, and fungi. Due to this, it is particularly useful for products that are sensitive to temperatures or moistures such as plastics, electronic parts, and intricate-designed complex laparoscopic instruments. This is the greatest guarantee for high sterility.
Importance of ETO Sterilizers in Laparoscopy
Those medical instruments used in laparoscopic surgery are specifically designed with specialized tools, trocars, laparoscopes, and endoscopes, which are fragile and contain electrical and optical components that cannot be sterilized with steam sterilization autoclave procedure because of the involved high temperature. The ETO sterilizer for laparoscopy is effective in this case because it can undertake the complete cycle without the involvement of high temperatures to preserve the integrity and functionality of these sophisticated instruments.
ETO Sterilization Process of Laparoscopic Instruments
The general ETO sterilization process involves four steps, namely preconditioning, gas exposure, evacuation, and aeration. Preconditioning is the procedure of heating the instruments to their optimum temperature to allow penetration by ETO. The exposure phase entails filling the sterilizer chamber with ethylene oxide gas, to allow the filling of all surfaces of the instruments for easy penetration of the gas through all parts of the equipment during the sterilization process.
Benefits of ETO Sterilizers
The use of an eto sterilizer for orthopaedic has several advantages, such as radical sterility in complex tools and tolerance to sensitive materials. Even objects sensitive to moisture can be sterilized.
An ETO sterilizer for laparoscopy is one of the most important elements used in modern surgery, constituting an effective and reliable way to have high standards in sterility and patient health.
