Bipolar pulse generation circuit, device and method

Abstract

The embodiment of the invention provides a bipolar pulse generation circuit, device and method. The bipolar pulse generating circuit comprises a pulse generating unit and a driving unit, the pulse generation unit comprises at least one pulse generation module which is cascaded in sequence; the second end of the first switch module and the second end of the second switch module of the previous pulse generation module are electrically connected with the second end and the first end of the first energy storage module of the next pulse generation module respectively; and the control circuit is used for generating a first control signal and transmitting the first control signal to each gate drive circuit group, and the pulse generation unit outputs a design pulse signal to a load. According to the embodiment of the invention, the bipolar pulse signal can be output to ensure the ablation effect, the magnetic drive transformer controls the switch to be switched on synchronously through one wire, the switch module is protected, and the quick voltage recovery requirement of the first energy storage module of the pulse generation module is met.

Description

technical field [0001] The present application relates to the field of pulse technology, and in particular, the present application relates to a bipolar pulse generating circuit, device and method. Background technique [0002] As a non-thermal ablation technique, the high-voltage pulse technique has been paid more and more attention in clinical application. High-voltage pulse technology generates a high-voltage pulsed electric field with a pulse width of milliseconds, microseconds or even nanoseconds to release extremely high energy in a short period of time, which can make cell membranes and even intracellular organelles such as endoplasmic reticulum, mitochondria, Nuclei, etc. will produce a large number of irreversible micropores, resulting in the apoptosis of diseased cells, and then achieve the desired therapeutic purpose. [0003] High-voltage pulse technology is widely used in various diseases. For example, in the application of tachyarrhythmia, the use of high-volt...
