Abstract:
1. An electrosurgical instrument for the coagulation of biological tissue comprising: a tubular probe for passing a noble gas from a gas source to at least two outflow openings defined in a distal end region of the probe, the at least two outflow openings each having a slit-like structure; and an electrode device disposed in the distal end region of the probe for being connected to an HF source for ionizing said noble gas in order to supply a coagulation current via said noble gas to said biological tissue; the at least two outflow openings being provided, disposed opposite one another with their long axes oriented perpendicular to or at an angle to, but not parallel to a long axis of the probe, and the probe being flexibly constructed at least in the region of the outflow openings, in such a way that when the probe is bent in the region of the outflow opening, their cross sections are enlarged or reduced.
