Abstract

With any monopolar device that is used to cut or cauterize tissue, eschar typically builds up on the exposed electrode, creating inefficiency with the energy discharge and necessitating the user to clean the electrode to improve performance. Having this feature incorporated on the device would provide an improved means to clean off the eschar from the electrode tip. This ability would decrease the need to remove the device from the therapy site, therefore decreasing the number of instrument exchanges and increasing the surgical efficiency of the procedure.

Monopolar Electrode Tip Cleaning

Summary

With any monopolar device that is used to cut or cauterize tissue, eschar typically builds up on the exposed electrode, creating inefficiency with the energy discharge and necessitating the user to clean the electrode to improve performance. Having this feature incorporated on the device would provide an improved means to clean off the eschar from the electrode tip. This ability would decrease the need to remove the device from the therapy site, therefore decreasing the number of instrument exchanges and increasing the surgical efficiency of the procedure.

Description

Several methods are proposed to clean off eschar from a monopolar tip.

In Figure 1, a non-conductive sleeve is affixed to the electrode area. Separate from the electrode extension and retraction actuation, the push rod can be deployed when eschar becomes an issue. It functions by sliding along and around the electrode axis

In Figure 2 , a wiper can be configured to extend over the electrode as desired to clean off the eschar.

In Figure 3, a wiper can be affixed within the shaft; to clean, the electrode would be moved proximally to clean off the eschar.

In Figure 4 & 5, a wiper plug can be affixed within the shaft; to clean, the electrode would be moved proximally to clean off the eschar.
