Electrophysiological catheter

The invention relates to an electrophysiology catheter. The electrophysiology catheter comprises an inner tube and an outer tube which are connected in a sleeved mode, the inner tube and the outer tube can move relatively, the electrode assembly enables the inner tube and the outer tube to be connected, the electrode assembly comprises a plurality of base body sets, the base body sets are arranged in the circumferential direction of the inner tube, the base body sets are connected with the inner tube and the outer tube, each base body set comprises two or more base bodies sequentially arranged in the circumferential direction of the inner tube, and the base bodies are arranged in the circumferential direction of the inner tube. The base body can deform and at least comprises a first section and a second section which are connected, a first connecting point is arranged between the first section and the second section, and the first connecting points in the same base body group are in contact connection to form
