Abstract

An end effector of an electrosurgical device may include one or more electrodes and a movable electrode scraper having a plurality of features in mechanical communication with a surface of the one or more electrodes and configured to move across the surface of the electrodes thereby removing biological debris adhering to the surface of the electrodes. The electrosurgical device may include a diverter in mechanical communication with the one or more electrodes. The scraper may also be configured to move across the surface of the diverter. The scraper may be operated by the action of an extendable mechanism in mechanical communication with a shaft of the electrosurgical device. An end effector of an electrosurgical device may include one or more electrodes and a movable electrode sleeve configured to movably cover the one or more electrodes.
