Abstract
A medical TFT instrument of the bipolar design includes at least two electrodes held by electrode carriers movable relative to each other which can be charged with HF current via a respective feed line. A safety switch mechanism arranged in the area of the electrode carriers and interconnected in at least one of the feed lines is additionally provided which, upon transfer of at least one of the electrode carriers into the out-of-function/situation, is brought into an OFF or disconnect position, whereby a HF current supply to the electrode associated with this feed line is disconnected.

A medical TFT instrument of bipolar design comprising at least two electrodes being held by electrode carriers movable relative to each other which can be charged with HF current via a respective feed line, the medical TFT instrument including a safety switch mechanism arranged in the area of at least one of the electrode carriers and interconnected in at least one of the feed lines, which safety switch mechanism is brought into an OFF or disconnect position only upon transferring the at least one electrode carrier into the out-of-operation position or situation in which no more interaction of the two electrodes is possible or intended, thereby HF current supply to the electrode associated with the feed line being disconnected.
