Abstract: A medical instrument is provided for cutting tissue or vessels in the human or animal body. The instrument comprises two scissor arms pivotal with respect to one another, each having a cutting edge. The cutting edges slide across one another when the scissor arms are pivoted. The first and second scissor arms are configured as electrodes to be supplied with high frequency current and pivotal about a stationary pivot axis arranged at the scissor arms. At least one of the scissor arms comprises at least one bracket connected thereto, which at least partially extends over the outer side of the other scissor arm.
