Abstract

An electrosurgical instrument for making an end-to-end anastomosis between two hollow organ sections includes two tools movable relative to each other and each including an HF electrode by which the hollow organ sections can be fusion-welded to each other. The two tools are substantially sleeve-shaped or can at least be brought into sleeve shape so that a first tool can enclose a first hollow organ section and a second tool can enclose a second hollow organ section. Each of the electrodes is formed on an end face of each sleeve-shaped tool around which the respective hollow organ section can be everted inside out, and the two tools are movable relative to each other so that the electrodes are aligned and can clamp the everted hollow organ sections therebetween.
