The invention relates to tissue scissors () with improved stability and improved handling that have two structurally and electrically different branches (). While the sliding surface () of the first branch () has a metal-ceramic hard material layer (), such as, for example, titanium nitride, the second sliding surface () of the second branch () has an electrically non-conductive ceramic layer (). The material mating produces great mechanical resistance to abrasion in the bearing () and on the cutting edges (). At least one of the branches, in particular branch (), can have a cermet body () to improve the cooling of the cutting edge (()) and/or keep it sharp, to prevent heating of the branches () during coagulation and sticking of the tissue.

Tissue scissors for biological tissue

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.

Bipolar clamp for HF surgery

The invention relates to a bipolar clamp () comprising two scissor members (), which are joined together mechanically by means of an insulating screw or similar pivot joint () about which they can rotate with respect to one another, but are electrically insulated from one another, In accordance with the invention the current-supply means () are so disposed, and the ratchets () are so constructed, that current flow from the current-supply means () to the electrode components () is possible only in the closed position. These measures make manipulation of the bipolar clamp () safer, because a coagulation current cannot flow until the clamp is in the closed position.
