Abstract: Bipolar medical instrument for cutting tissue under the action of high-frequency current, wherein the instrument extends along a longitudinal direction from a proximal end to a distal end, wherein an active electrode and a neutral electrode, adjacent to the active electrode, are arranged at the distal end, and wherein the neutral electrode has a curved profile with a first curvature and a second curvature, wherein the respective directions of the curvatures are different. An electrosurgical system is also disclosed, with a high-frequency generator, and with one such bipolar medical instrument, which can be attached to the high-frequency generator.
