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.
