Bipolare Koagulationselektrode

Abstract

The invention concerns a bipolar coagulation probe ( 10 ) having an electrode tip ( 14 ) which has an end face ( 16 ) in which a pole ( 17 ) of a first electrode ( 18 ) and a pole ( 19 ) of a second electrode ( 20 ) are integrated. In accordance with the invention the bipolar coagulation probe ( 10 ) includes a temperature control unit ( 26 ) with a temperature control medium for temperature control of the end face ( 16 ).

1 - 15 . (canceled)  
   
   
       16 . A bipolar coagulation probe having a proximal 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, characterised in that the coagulation probe includes a temperature control unit which is adapted to temperature-control the coagulation probe in the region of its distal end by means of a temperature control medium.  
   
   
       17 . A coagulation probe as set forth in  claim 16  characterised in that the temperature control unit includes a guide structure for the temperature control medium, with which the temperature control medium is to be guided to a rear side of the end face and from there at least partially deflected and guided back again.  
   
   
       18 . A coagulation probe as set forth in  claim 17  characterised in that the temperature control medium is a sterile, pyrogen-free physiological saline solution.  
   
   
       19 . A coagulation probe as set forth in  claim 17  characterised in that the temperature control medium is deionised water.  
   
   
       20 . A coagulation probe as set forth in  claim 16  characterised in that the temperature control unit is connected to a peristaltic pump.  
   
   
       21 . A coagulation probe as set forth in one of  claim 16  characterised in that the end face has bores through which the temperature control medium can issue.  
   
   
       22 . A coagulation probe as set forth in  claim 21  characterised in that the bores are in the poles.  
   
   
       23 . A coagulation probe as set forth in  claim 16  characterised in that the pole of the second electrode is of an annular configuration and the pole of the first electrode is arranged within the annular pole of the second electrode.  
   
   
       24 . A coagulation probe as set forth in  claim 16  characterised in that the first electrode is tubular at least in the region of the electrode tip, wherein a distal end of the tubular first electrode forms the pole in the end face.  
   
   
       25 . A coagulation probe as set forth in  claim 16  characterised in that the first electrode assumes the form of a sleeve at least in the region of the electrode tip, wherein a distal end of the first electrode forms the bottom of the sleeve or the pole in the end face.  
   
   
       26 . A coagulation probe as set forth in  claim 16  characterised in that the second electrode is tubular at least in the region of the electrode tip, wherein a distal end of the tubular second electrode forms the pole in the end face.  
   
   
       27 . A coagulation probe as set forth in  claim 16  characterised in that the coagulation electrode includes at least two electrodes with a pole arranged at the periphery of the electrode tip.  
   
   
       28 . A coagulation probe as set forth in  claim 27  characterised in that the pole of the electrode, which is arranged at the periphery of the electrode tip, extends in an annular configuration around the electrode tip.  
   
   
       29 . A coagulation probe as set forth in one of claims  27  characterised in that an electrode has both a pole surface in the end face and also a pole surface at the periphery of the electrode tip.  
   
   
       30 . A coagulation probe as set forth in  claim 29  characterised in that the coagulation electrode includes a total of three electrodes.
