The instrument includes a pair of coagulation electrodes adapted to be connected to the terminals of a high-frequency voltage source and having spread-apart ends subjected to a biasing force tending to maintain the ends spread apart. An outer tube surrounds the coagulation electrodes. The spread-apart ends of the electrodes project outwards from inside the outer tube. The outer tube includes two handles and is shiftable relative to the electrodes by the handles at least against the ends of the electrodes and at least partly over the ends of the electrodes to press together the ends of the electrodes. The electrodes may also be rotated relative to the outer tube and the handles. |
