Abstract: Provided is a bipolar electrode probe, which includes a conductive needle, an insulation layer, a conductive sleeve, and an insulation sleeve. The conductive needle has a longitudinal direction and a transverse direction perpendicular to the longitudinal direction. The insulation layer covers the conductive needle and has a first opening. The conductive sleeve covers the insulation layer and has a second opening. The insulation sleeve covers the conductive sleeve. When the bipolar electrode probe is turned on, a longitudinal electric field is formed from a front end of the conductive needle to the conductive sleeve along the longitudinal direction. A transverse electric field is formed from the conductive needle to the conductive sleeve via the first opening and the second opening along the transverse direction.

Abstract: An ablation device including a first electrode, at least one second electrode and a guiding sleeve is provided. The guiding sleeve is sleeved outside the first electrode and the second electrode, so as to fold the second electrode. The guiding sleeve is adapted to move along an axial direction of the first electrode, so as to adjust a length of the first electrode exposed by the guiding sleeve and enable the second electrode to be released and expand in a radial direction of the first electrode.
