Anti-corrosion electric ablation needle and ablation method

The anti-corrosion electric ablation needle comprises a cutter bar, the cutter bar is divided into an insulating part and a conductive part, and the insulating part and the conductive part can be connected in an integrated mode or a spliced mode; the conductive part is connected with the electric generator to perform electrochemical ablation and/or electroporation ablation on the target area; the conductive part does not generate an electrolytic product when an electrolytic reaction occurs, and a corresponding device for cold/heat ablation, such as a fluid pipe, can be arranged in the cutter bar; the electrode has the advantages that no toxic electrolytes are generated in the body of a patient when electrochemical ablation is carried out in the body of the patient, and meanwhile, compared with precious metal electrodes such as platinum, the problem that toxic substances are generated due to corrosion of an electric ablation needle in a target area is solved in a relatively low-cost mode; and the device is app
