Claim 0:
1. 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;

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, wherein:
a central axis of the working electrode is coincident with a central axis of the support arm and intersects with a central axis of the counter electrode.
