The present invention relates to the technical field of medical devices, and particularly to a variable-frequency
electric field generating
system and its application in the treatment of
pathological angiogenesis, including: an
alternating current power generator for generating a
sine wave signal with a frequency of 500 - 1500 kHz and an amplitude of 50 - 100 Vpp; a wire, the first end of which is connected to the output end of the
alternating current power generator. The present invention suppresses the generation of pro-angiogenic factors at the
lesion site by generating a medium-
high frequency alternating
electric field, and has a better effect on suppressing
pathological angiogenesis. Compared with the prior art (such as
bevacizumab, injection sclerosing agent, endovascular interventional
embolization,
surgical resection, radiotherapy,
hormone therapy, etc.), the device of the present invention suppresses
pathological angiogenesis through an alternating
electric field, and has the advantages of non-invasive (used on the
body surface) or minimally invasive (implanted in the body), safe, locally applied, no systemic adverse reactions, pure physical and
pollution-free, etc.
