Title:
TISSUE ABLATION APPARATUS, AND ELECTROCHEMICAL IMPEDANCE MEASUREMENT APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/011931
Kind Code:
A1
Abstract:
The present application provides a tissue ablation apparatus, and an electrochemical impedance measurement apparatus and method. In the present application, by detecting, in real time, a Faradaic current participating in an electrochemical reaction of a target tissue (800) and a voltage difference between a first output end and a second output end of a high-voltage pulse module (100), a corresponding electrochemical impedance parameter of the target tissue can be obtained according to an electrochemical impedance fitting function, such that the amount of bubbles generated by the target tissue in an ablation process can be obtained according to the electrochemical impedance parameter of the target tissue, feedback control for an outputted high-voltage pulse signal is facilitated, and the amount of generated bubbles is controlled in time. According to the present application, a bubble extraction condition can be obtained while a high-voltage pulse signal is outputted for tissue ablation, an additional detection signal does not need to be generated, and the working efficiency is higher.
