Abrégé
(EN) The inventive application device for applying a high-frequency current for thermally obliterating body tissue comprises: an electrode needle (1) having an electrically conductive shank (3); at least one insulating sheath body (7), which surrounds the electrically conductive shank (3), can be displaced relative to the shank (3), and which is provided with a distal end, out of which the shank (3) can be extended, and; at least one trocar (5) that has a section provided for inserting into body tissue, a section (11) provided for remaining outside of the body tissue, and a lumen, which extends through both sections and through which the shank (3) of the electrode needle (1) can be guided through the trocar (5). The inventive application device is characterized in that the section of the trocar (5) provided for inserting into body tissue is designed so that it is electrically insulating and forms the sheath body (7) for the shank (3) of the electrode needle (1) particularly when the electrode needle or shank (3) thereof is guided through the lumen. The trocar (5) accomplishes two functions. Firstly, it accomplishes the traditional duties of a trocar (5), namely enabling the precise administration of medicaments or the taking of tissue samples as well as the insertion of electrode needles (1), without having to re-puncture each time. Secondly, the portion of the trocar (5) located inside the body serves as an insulating sheath body (7), which can be displaced relative to the shank (3) of the electrode needle (1) and which is provided for adjusting the length of the active area of the shank (3), i.e. of the area that projects out of the insulating sheath body (7), and is in electrically conductive contact with the body tissue when the electrode needle (1) is inserted into the body.
