1. A method for guiding interventional surgery using a catheter with a puncture needle on its tip to be inserted into a blood vessel of a patient, comprising:
receiving, by an interface, a plurality of intracardiac echocardiography (ICE) images of a target object of the patient acquired within a predetermined period;
performing, by a processor, image analysis on the plurality of ICE images to obtain image analysis results;
performing, by the processor, object detection using a large-scale learning model to detect at least one object from the plurality of ICE images based on the image analysis results;
simulating, by the processor, a plurality of geometric changes of the at least one object caused by the puncture needle in different candidate puncture positions on the at least one object, wherein each of the plurality of simulated geometric change simulates, in response to a simulated puncture performed by the puncture needle, how the at least one object would change in shape before the at least one object being physically punctured through by the puncture needle;
determining, by the processor, a candidate puncture position among the different candidate puncture positions of the plurality of simulated punctures as a target puncture position based on the plurality of simulated geometric changes; and
generating, by the processor, an interventional surgical plan to guide the interventional surgery including physically puncturing the at least one object at the target puncture position.
