The disclosure provides a probe arrangement having a distal probe tip and a proximal hand portion 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 hand portion and contacts the first electrode in the distal probe tip. An outer conductor of the probe arrangement extends from the distal probe tip to the proximal hand portion and serves to electrically contact the second electrode in the distal probe tip. The inner and outer conductors of the probe arrangement are electrically insulated from each other. Furthermore the inner conductor is selected in such a way that the flexural stiffness of the probe arrangement is increased between the probe tip and the hand portion.
A probe arrangement for the electrothermal coagulation of tissue comprising a distal probe tip and a proximal hand portion, comprising
A probe arrangement as set forth in one of the preceding claims characterized in that the distal end (10b) of the inner conductor (10) can be screwed to the probe tip and the proximal end (10a) of the inner conductor (10) is adapted to be braced in relation to the hand portion.
A probe arrangement as set forth in one of the preceding claims characterized in that the inner conductor (10) has a hollow duct (15) which is adapted to pass cooling or heating fluid from the proximal end to the distal end, and a through bore (16) which is adapted to allow the heating or cooling fluid supplied through the hollow duct (15) to be discharged from the hollow duct (15), and provided between the insulator (18) and the outer conductor (19) is an intermediate space (20) which is adapted to pass the cooling or heating fluid of the hollow duct (15), which is flowing out of the through bore (16), back to the proximal end.
