  • both electrodes are connected to an HF generator and arranged in mutually fixed dimensions, for example on an insulating support, and are placed by the surgeon in the immediate vicinity of the treatment site and generally also actively guided.
  • a bipolar electrode arrangement with a liquid channel is known from WO 97/17009, via which rinsing liquid can be introduced into the engagement area.
  • Two or three electrodes are arranged as a conical section on a conical distal tip of the instrument, which can be inserted into the tissue, the electromagnetic RF field being formed between the electrodes and intended to coagulate the surrounding tissue.
  • An electrode arrangement for a surgical instrument for the electrothermal coagulation of tissue is known from WO 00/36985.
  • Such an electrode arrangement is shown in FIG. 13 and in this case has an electrically conductive front cylinder 110 at the distal end of the instrument with a distal tip 112 and a cylindrical first electrode 182, a tubular outer conductor proximal to the front cylinder with a cylindrical second electrode 184 and Insulator element 170a between the front cylinder 110 and the outer conductor, the electrodes being connectable to an AC voltage source.
  • the first electrode 182 is designed as a self-supporting tubular section which sits between the front cylinder 110 and an insulating tubular first carrier 170a.

  • the electrodes 182, 184 are electrically contacted via wires 190.
  • a cooling fluid can also be used to cool an electrode arrangement.
  • this cooling fluid can be gaseous or liquid.
  • the object of the invention is therefore to provide a probe arrangement for the electrothermal coagulation of tissue with improved strength.
  • the invention is based on the idea of providing a probe arrangement with a distal probe tip and a proximal handpiece for the electrothermal coagulation of tissue.
  • the probe arrangement has at least a first and a second electrode in the region of the distal probe tip.
  • An inner conductor of the probe arrangement extends from the distal probe tip to the proximal handpiece and makes electrical contact with the first electrode in the distal probe tip.
  • An outer conductor of the probe assembly extends from the distal tip of the probe to proximal handpiece and was used to electrically contact the second electrode in the distal probe tip.
  • the inner and outer conductors of the probe arrangement are electrically insulated from one another.
  • the inner conductor is also selected in such a way that the bending stiffness of the probe arrangement between the probe tip and the handpiece is increased.
  • a positive or non-positive connection of the outer conductor as well as the inner conductor with the probe tip on the one hand and the handpiece on the other hand leads to the fact that both the outer conductor and the inner conductor contribute to the area moment of inertia and thus increase the bending strength.
  • the inner conductor is connected to the handpiece and the probe tip in such a way that the inner conductor is under tensile stress and the outer conductor is under shear stress. This leads to a further increase in the stability of the probe arrangement.
  • the inner conductor is designed as a metal tube.
  • the use of a metal tube has the advantage that the metal tube serves as an electrical lead for the first electrode, the supply of the cooling medium and the increase in the rigidity and breaking strength of the probe arrangement.

This enables quick assembly and simple replacement of the individual parts of the probe arrangement without impairing the stability of the probe arrangement.
  • an insulator is provided between the inner and outer conductors in order to electrically insulate the inner conductor from the outer conductor. Unwanted short circuits between the inner and outer conductors, which can seriously disrupt the operation of the probe arrangement, can thus be avoided.

  • the first electrode is designed as a tip electrode and the second electrode as a shaft electrode.
  • an insulator element which is preferably designed in a ring shape, which is designed to isolate the tip electrode from the shaft electrode in order to avoid short circuits.
  • the probe arrangement has an insulation tube which is put over the outer conductor in order to electrically insulate it from adjacent tissue.
  • the handpiece has a first handpiece element which receives the proximal ends of the inner conductor, the outer conductor, the insulator and the insulation tube.
  • the first handpiece element has a first blind bore and a longitudinal slot, which serve to guide an electrically conductive spring wire in the longitudinal slot from the proximal end of the first handpiece element to the first blind bore in order to Electrical contact in the first blind hole.
  • the first handpiece element also has a transverse bore and a second blind bore.
  • the second blind hole is also connected to the space between the insulator and the outer conductor.
  • the cross hole and the second blind hole cross each other and thus there is a connection between the proximal end of the handpiece element and the intermediate space.
