Self-adaptive follow-up pulse ablation system and method

Abstract

The invention provides a self-adaptive follow-up pulse ablation system which comprises a power supply system, an isolation transformer, a high-voltage power supply, an energy storage system, a pulse generation system, a pulse monitoring system, a pulse switching system, an electrode system, a control system, an isolation system, an acquisition system, a positioning system, a follow-up system, an upper computer system and a cloud platform. The optimal treatment parameter range is provided for each treatment process by adopting a cloud platform and an artificial intelligence algorithm, and the pulse (group) parameters are adaptively adjusted in real time in the treatment process, so that the shaking degree and the temperature rise condition of the biological tissue are both within the threshold range, the relative displacement and the relative rotation of the electrode and the treatment part are reduced, and the treatment effect is improved. The optimal treatment effect and the minimum side effect are achieved; meanwhile, the self-adaptive follow-up pulse ablation system and method can reduce the influence of anisotropy of biological tissues at the tumor part, so that the pulse ablation is more uniform, and the ablation effect is better.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular to an adaptive follow-up pulse ablation system and method. Background technique [0002] Pulse ablation has received extensive attention in recent years. Compared with traditional ablation methods, it has the advantages of short treatment time, convenient treatment, less sequelae, and preservation of blood vessels and nerves. [0003] In today's pulse ablation systems, unipolar pulses are mostly used, but the pulse voltage basically exceeds the threshold voltage of muscle contraction, so it will cause muscle contraction and lead to electrode displacement, which will adversely affect ablation; especially It is that when it acts near the heart, it can cause disturbance of cardiac contraction, with dangerous consequences. [0004] Methods such as injection of muscle relaxants can be used to reduce muscle contraction and shaking, but the use of muscle relaxants requires additio...

Problems solved by technology

[0006] But for biological tissues, its parameters are often anisotropic, and the same voltage, current, electric field, and magnetic field have different effects in anisotropic biological tissues; this shows that pulses of the same intensity can cause cardiac It is different from the contraction intensity of muscles, so even positive pulses and negative pulses with the same intensity cannot be completely offset, and it will also cause muscle contraction and shaking

[0007] Furthermore, the parameters of biological tissue are constantly changing during the ablation process, and the number of ablation pulses and / or pulse groups is preset in the existing ablation systems, which will have a large difference with the actual ablation progress in the later stage of ablation. Deviation, so that the treatment can not achieve the expected effect or produce overtreatment
