| 摘要 |
The invention relates to a surgical probe comprising a handle and a shaft that is connected to the handle, and two axially interspaced electrodes, the electrode closer to the handle forming a proximal electrode and the other electrode further from the handle forming a distal electrode, said electrodes respectively forming an outer surface of the shaft and being separated by an insulator. The outer diameter of the two electrodes and the outer diameter of the insulator are approximately the same and the shaft has a fluidic passage for a cooling fluid, which extends inside the shaft, from the handle to the distal electrode. The inventive surgical probe is characterised in that the shaft comprises a single-component hollow body that is connected to the handle, forms the distal electrode, and carries the insulator, the proximal electrode and an insulation layer arranged in the radial direction between the hollow body and the proximal electrode.
