It is a cone-shaped electrode made of steel tubing, the development of which was based on the reduction of the trauma it caused. It is easy to see that the conical is significantly smaller than a cylindrical electrode, so the trauma it causes during insertion is significantly reduced. Another advantageous feature is the symmetrical structure of the electrode, as a result of which the tissue is spread evenly during insertion, thus causing less damage than a U-probe shaped like the tip of a hypodermic needle.
It can also be seen that the distance between the tip of this electrode and the last lead point is also significantly smaller. The mechanical stability of the electrode is enhanced by the fact that the back of the conical part is also made of steel. With this type, it is also possible to use a liquid channel or fiber optics in the first half and a third of the electrode.
The electrode is suitable for piercing the puncture in smaller animals. The tip of the electrode can be slightly dimmed if required, thus reducing the distance between the last point and the physical end of the electrode.
