What are the correct ways to disinfect the electric knife pen of the electrosurgical unit?

1. During the use of the electrosurgical knife, after each use of the knife head, wait until it is completely cooled, then wipe off the residual tissue of the knife head with gauze soaked in physiological saline, and then disinfect it. Electrodes can be sterilized by high temperature and high pressure (134°C for 3-5 minutes, 121°C for 10-20 minutes).

2. Sterilize with ethylene oxide: After packaging, put the medal into the medal for 16-24 hours, and it can be used after degrading in the air environment for one hour.

3. Soak in 2% glutaraldehyde for 30 minutes, wash with normal saline, and it can be used (using this method will affect the service life of the electrode).

4. Before using the electric knife, when checking the electric knife circuit (power-on), the knife head should be installed first, and the power-on is also the process of secondary disinfection.
