Abstract: The invention concerns an electrode arrangement for a surgical instrument for the electrothermal coagulation of human or animal tissue, comprising an elongate carrier, at least two electrodes which extend in the longitudinal direction of the carrier and which are connectable to an external ac voltage, and a plurality of self-supporting metal bar profile members which extend in the longitudinal direction of the carrier and which are connected together by means of one or more insulating spacer elements and form the electrodes. It is achieved in that at least one bar profile member is in the form of a hollow profile member or a solid profile member.

Abstract: The disclosure concerns electrically operated medical products, which are to be brought electrically into operation by being switched on or in conjunction with an electrical power source, including a reuse blocking device that is connectable to the power source and is designed in such a way that when the product is brought into electrical operation for the first time, the reuse blocking device is so initialized and is so altered in its state that operation of the medical product is possible as long as the surgical instrument is connected to the power source or the power source is switched on and the reuse blocking system prevents renewed use after disconnection from the power source or only allows a number of use cycles, which is predetermined by the manufacturer.

Abstract: An arrangement (1) for electrothermally treating the human body or an animal body, in particular for tissue coagulation or electrotomy, includes two electrodes (3, 4) for insertion into the body to be treated. The two electrodes (3, 4) are electrically insulated from each other and are disposed at a distance from each other to produce an electric or electromagnetic field heating the body tissue in the treatment area, and each electrode is connected by a feed line with a power source arranged outside the body. An elongate catheter (2) is provided for joint insertion of the two electrodes (3, 4) into the body, which are staggered in relation to each other in the axial direction of the catheter (2) and connected to the catheter (2) or a component thereof.

Abstract: A cutting device for use in electrotomy is disclosed for use with a high frequency generator to make a cut in a cutting direction. The cutting device comprises a carrier element, and first and second electrodes each connected to the high frequency generator. Each electrode has a proximal portion attached to the carrier element and an elongated distal leg portion which terminates in a distal end. An insulation element connects the distal ends to each other with predetermined spacing between them. The elongated segments oppose each other and are aligned to be co-linear with each other along the cutting direction.
