Abstract
Electrosurgical instrument for the coagulation of biological tissue, wherein from a gas source a noble gas is sent through a tubular probe to at least one outflow opening in a distal end region of the probe, with an electrode device disposed in the distal end region of the probe, which can be connected to an HF source in order to supply a coagulation current, and wherein the at least one outflow opening has a slit-like structure, such that at least two outflow openings are 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 that the probe is 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 openings, their cross sections are enlarged or reduced.
