Title:
CLOSED-LOOP CONTROL SYSTEM FOR PULSE ABLATION
Document Type and Number:
WIPO Patent Application WO/2023/098896
Kind Code:
A1
Abstract:
A closed-loop control system for pulse ablation. The system comprises an electric pulse host (100) and an electrode group. The electric pulse host (100) comprises two paths of control. One path is a control circuit, which is formed by means of sequentially connecting a main control module (110) to a pulse sending module (120), a first electrode control unit (140) and the electrode group, wherein the main control module (110) controls the pulse sending module (120) to output a pulse signal, and a specific electrode is selected by means of the first electrode control unit (140) to release a pulse signal to act on an ablation part. The other path is a feedback circuit, which is formed by means of sequentially connecting the main control module (110) to an electrophysiological signal sampling module (130), a second electrode control unit (150) and the electrode group, wherein the main control module (110) selects an electrode (200) by means of the second electrode control unit (150); an electrocardiogram signal is sampled by means of the electrophysiological signal sampling module (130); and the main control module (110) determines a treatment progress according to the sampled electrocardiogram signal, and adjusts, in real time and according to the treatment progress, a pulse signal that is output by the pulse sending module (120).
