The utility model relates to a device for delivering pulse electric field ablation energy to endocardium tissue, and belongs to the technical field of medical instruments. Comprising an ablation device, a handle, a pulsed electric field generator and a control system, the ablation device is connected with the pulsed electric field generator and the control system through the handle; the ablation device is provided with a plurality of positive and negative alternate electrodes, and the ablation device is of a multi-layer spiral conical structure which is in contact with endocardium tissue and can be movably folded and unfolded. Compared with the prior art, the utility model has the characteristics that different parts can be ablated at the same time, the electric field ablation range is larger, the ablation effect is more thorough, the manual operation action of a doctor can be greatly reduced, the exposure time in a radiation environment is reduced, the complexity and the error rate of surgical operation are
