Patent ID: 8157799

Claim:
A bipolar coagulation probe having a shank and a proximal end and a distal end and an end face at the distal end of the shank, in which a pole of a first electrode and a pole of a second electrode are integrated, characterized in that the coagulation probe includes a temperature control unit which is configured to temperature-control the coagulation probe in the region of its distal end by means of a temperature control medium; and further characterized in that the first electrode has the form of a metal sleeve with a spherical end surface at least at the distal end, the metal sleeve is arranged centrally at the distal end and forms the pole of said first electrode, and said pole of said first electrode is surrounded by the second electrode which is tubular at the distal end, whereby the metal sleeve forming the pole of the first electrode is surrounded by the second pole of the second electrode, wherein the temperature control unit includes a guide structure for the temperature control medium, with which the temperature control medium is guided to a rear side of the end face and from there at least partially deflected and guided back again; and wherein the guide structure includes a tube which is located substantially centrally within the shank and in which the temperature control medium is conveyed to the rear side of the end face and the guide structure guides the temperature control medium back past the tube on an outside of the tube.
