摘要： A bipolar clamp for high-frequency surgery, in particular for coagulating tissue, having at least two bipolar clamping parts which are movable relative to one another, defining a grasping region between an open position and a coagulation position (e.g., closed position) and having electrodes for coagulating tissue that is grasped by the clamping parts in the grasping region. The clamping parts are formed of an electrically conductive core which is surrounded by a thin-layer electrical insulation and the electrodes are arranged on the clamping parts as thin pin electrodes that protrude through the thin-layer electrical insulation into the grasping region.

摘要： An electrosurgical device for coagulating and/or cutting biological tissue that includes an instrument for application of high-frequency current, an activation switch, a high-frequency generator, and a safety unit. The instrument for application of the high-frequency current includes first and second branches having respective first and second jaw parts that are connected such that they are movable relative to one another. The safety unit interrupts the current supply to electrodes of the instrument when the jaw parts assume a position relative to one another that is not suitable for coagulation by means of the high-frequency current, e.g. when the jaw parts are open. Thus, erroneous operation of the device may be prevented.

摘要： The invention relates to a bipolar clamp (10) comprising two scissor members (12, 14), which are joined together mechanically by means of an insulating screw or similar pivot joint (16) about which they can rotate with respect to one another, but are electrically insulated from one another, electrode components (18, 20) at distal ends (22, 24) of the scissor members (12, 14) for grasping tissue and conducting an electrical current through the tissue to cause. coagulation, handle devices (26, 28) at proximal ends (30, 32) of the scissor members (12, 14), current-supply means (34, 40, 42) at the proximal end (32) of one scissor member (14) ratchets (36, 38) between the pivot joint (16) and the proximal ends (32, 34) to lock, the scissor members (12, 14) to one another in a closed position. In accordance with the invention the current-supply means (34, 40, 42) are so disposed, and the ratchets (36, 38) are so constructed, that current flow from the current-supply means (34, 40, 42) to the electrode components (18, 20) is possible only in the closed position. These measures make manipulation of the bipolar clamp (10) safer, because a coagulation current cannot flow until the clamp is in the closed position.
