Multifunctional pulse energizing device and processing method for the same

A multifunctional pulse energizing device, comprising:

• a multi-cavity component, defining a central cavity and a plurality of peripheral cavities surrounding the central cavity therein;
• the plurality of peripheral cavities and the central cavity extending along an axial direction without communicating with each other;
• wherein a portion of the multi-cavity component between a proximal end and a distal end in the axial direction is cut along the axial direction into a plurality of sub-tube portions that are separated in a circumferential direction of the multi-cavity component;
• each of the plurality of sub-tube portions is provided with a respective peripheral cavity therein, and each of the plurality of sub-tube portions is provided with a through hole communicating with the respective peripheral cavity;
• at least a portion of the multi-cavity component from the plurality of sub-tube portions to the distal end is provided with a multi-layer structure;
• and the multi-layer structure comprises a cutting layer and an inner layer, the cutting layer is configured to form the plurality of sub-tube portions, and the inner layer is configured to form a central component;
• a plurality of first electrodes, each of the plurality of first electrodes being mounted around a corresponding sub-tube portion and configured to deliver a pulse current;
• a second electrode disposed at a distal end of the central component, and configured to perform single-point discharge;
• and
• a third electrode, disposed at a distal end of the cutting layer, and configured to perform single-point discharge.
