Electrosurgical instrument with telescoping suction port and debris cleaner

An end effector of an electrosurgical device, the end effector comprising:

• a first electrode having an exposed longitudinal extent and a second electrode having an exposed longitudinal extent;
• a diverter comprising a planar top surface, a planar bottom surface in opposition to the planar top surface, a first terminal lateral side in mechanical communication with an inner surface of the exposed longitudinal extent of the first electrode and a second terminal lateral side in mechanical communication with an inner surface of the exposed longitudinal extent of the second electrode;
• a third electrode disposed on the planar top surface of the diverter between the inner surface of the exposed longitudinal extent of the first electrode and the inner surface of the exposed longitudinal extent of the second electrode;
• and a movable electrode scraper having a plurality of features in mechanical communication with a surface of the exposed longitudinal extent of the first electrode and a surface of the exposed longitudinal extent of the second electrode and configured to move across the surface of the exposed longitudinal extent of the first electrode and the surface of the exposed longitudinal extent of the second electrode thereby removing biological debris adhering to the surfaces of the first and second electrodes.

An electrosurgical device comprising:

• a first electrode and a second electrode;
• a housing configured to enclose a first portion of the first electrode and a first portion of the second electrode;
• a shaft extending distally from the housing configured to enclose a second portion of the first electrode and a second portion of the second electrode;
• an extendable mechanism in mechanical communication with the shaft;
• and
• an end effector, the end effector comprising:
• a third portion of the first electrode wherein the third portion of the first electrode has an exposed longitudinal extent and a third portion of the second electrode wherein the third portion of the second electrode has an exposed longitudinal extent;
• a diverter comprising a planar top surface, a planar bottom surface in opposition to the planar top surface, a first terminal lateral side in mechanical communication with an inner surface of the exposed longitudinal extent of the third portion of the first electrode, and a second terminal lateral side in mechanical communication with an inner surface of the exposed longitudinal extent of the third portion of the second electrode;
• and
• a movable electrode sleeve configured to movably cover at least a portion of a surface of the exposed longitudinal extent of the third portion of the first electrode, a portion of a surface of the exposed longitudinal extent of the third portion of the second electrode, and a portion of the planar top surface of the diverter under mechanical control of the extendable mechanism.
