Irreversible electroporation therapy equipment and bioimpedance measurement methods

Abstract

This application relates to an irreversible electroporation treatment device and a bioimpedance measurement method. The irreversible electroporation treatment device includes a high-voltage pulse module, a differential sampling module, a voltage processing module, a current sensing module, a high-frequency sampling module, and a main control module. This application uses the differential sampling module to divide and collect the voltages at the positive and negative output terminals of the high-voltage pulse module. This allows for real-time sampling of the high-voltage pulse signal during high-voltage pulse puncture in the irreversible electroporation treatment device. The voltage processing module, current sensing module, and high-frequency sampling module then obtain a digital feedback signal corresponding to the impedance of the target tissue. This eliminates the need to output an additional pulse signal during the output gap of the high-voltage pulse signal, enabling real-time acquisition of the target tissue's impedance.
