An instrument for surgical purposes, especially for coagulation, is proposed. This instrument has at least one arm, the tips of the arms having electrical contact regions which can be electrically connected to a control unit for touching a tissue for the purpose of coagulation. The contact regions are formed from doped diamond to produce the electrical conductivity.
