Abstract

The tissue sealing instrument according to the invention comprises two jaws that are both provided with sealing electrodes. While one of the jaws comprises a cutting electrode, the other comprises an elastic counter support. The cutting electrode is held in a flexible plastic body that is seated in a narrow groove. On the contrary, counter support is seated in a comparably substantially wider recess. Accordingly, counter support is wider (preferably considerably wider) than insulating body comprising the cutting electrode. This definition of different dimensions allows a wide scope for defining desired characteristics of the tissue sealing instrument.
