Claim 10:
11. A bipolar electrode instrument for use in a resectoscope, the electrode instrument including:
a first conductor that extends through an elongated shaft section and being configured to form a working electrode at a distal-most end of the electrode instrument, the working electrode configured to receive a high-frequency current;
a second conductor extending through the shaft section and forming a counter electrode at a distal end region of the electrode instrument such that the counter electrode is provided proximally of the working electrode, wherein:
the working electrode and the counter electrode are spatially separated such that a distance between the working electrode and the counter electrode cannot be bridged by a straight conductor having a length of 6 mm or less; and

an insulator arranged spatially between the working electrode and the counter electrode, the insulator intersecting all possible straight connecting lines between the working electrode and the counter electrode that are 6 mm or less in length; and
a support arm configured to carry the working electrode, the support arm being L-shaped, wherein the working electrode, counter electrode, and insulator are arranged concentrically about the support arm.
