Abstract

The invention discloses a cooperative pulse irreversible electroporation device which can be used for ablating tumor cells, and relates to the technical field of medical devices. The Cooperative pulseirreversible electroporation device mainly comprises a synergistic pulse generation circuit and at least one pair of electrodes, wherein the synergistic pulse generation circuit is used for outputting synergistic pulses including a first pulse of a high voltage / narrow pulse width and a second pulse of a low voltage / wide pulse width to the electrode for ablating tumor cells through the electrodes.The cooperative pulse irreversible electroporation device provided by an embodiment of that present disclosure can improve the therapeutic efficiency of a mass tumor.

Description

technical field [0001] The present disclosure relates to the technical field of medical devices, in particular, to an irreversible electroporation device capable of outputting coordinated pulses. Background technique [0002] There are many therapeutic instruments for cancer. In recent years, with the continuous development of pulsed bioelectricity, tumor therapeutic instruments based on electric field pulse technology have attracted extensive attention from researchers in the field of bioelectromagnetics due to their non-thermal and minimally invasive biomedical effects. focus on. [0003] In the application of electric field pulse technology, irreversible electroporation technology is a new application method. Irreversible electroporation refers to sending electric field pulses to the cells in the target area (typical pulse parameters are: field strength 1500-3000V / cm, pulse width 100μs, repetition frequency 1Hz, pulse number 70-120, unipolar square wave electric field pu...
