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.
