Abstract:
An apparatus for the high-frequency treatment of body tissue with a head (10), the head comprising a distal tip portion and at least one HF electrode (14) of an electrically conductive material, which can be brought into contact with the tissue (24) to be treated, wherein the head (10) supporting the HF electrode (14) is formed of a thermally highly conductive material onto which at least one electrode (14) is formed, wherein the head (10) comprises highly heat conductive portions (12) in order to dissipate the heat generating at the HF electrode (14) in the proximal direction, with the head (10) having a length of 6 to 12 mm and a diameter of 1.5 to 4 mm, wherein all HF electrodes (14, 14a, 14b, 14c) are arranged on the proximal side of the tip in a section of 1 to 6 mm of the longitudinal extension of the head (10), and the distal tip portion and the highly heat conductive portions include a highly heat conductive material.
