Abstract:
1. An apparatus for aiding coagulation of fluids in tissue during surgery comprising; a suction structure; a first electrode shaped as a U-shaped cylindrical section extending from an end of the suction structure, wherein the first electrode has rounded edges to provide even electric field distribution and to minimize tissue burning; a second electrode shaped as a U-shaped cylindrical section extending from an end of the suction structure and opposite from the first electrode, wherein the second electrode has rounded edges to provide even electric field distribution and to minimize tissue burning; a first air gap formed by a first circumferential distance between the first electrode and the second electrode, wherein the first circumferential distance is approximately equal to the distance between a tip of the first electrode and the suction structure; and a second air gap formed by a second circumferential distance between the first electrode and the second electrode, wherein the second circumferential distance is approximately equal to the distance between a tip of the second electrode and the suction structure.
