Abstract

The embodiment of the invention provides an ablation device and a pulse ablation system. According to the ablation device provided by the embodiment of the invention, a needle tube and a needle core of an ablation assembly are connected in a relative movement manner, a linkage assembly is switched between the state of fixing the needle tube and the state of fixing the needle core, the linkage assembly is driven to move through an adjusting assembly, then the needle core or the needle tube clamped by the linkage assembly is driven to move, and therefore, the length of a working area of the ablation assembly is adjusted. Therefore, the ablation assembly can be suitable for lesion tissues with different depths and / or sizes, and the application scene of the ablation device is widened; and moreover, after the needle core is in contact with the diseased tissue, the needle core does not need to be moved again, so that discomfort of a patient due to the fact that the needle core punctures the diseased tissue for many times is avoided.

Description

technical field [0001] The present application relates to the technical field of ablation electrodes, and in particular, the present application relates to an ablation device and a pulse ablation system. Background technique [0002] With the development of the field of bioelectromagnetic technology, IRE (IRreversible Electroporation, irreversible electroporation) technology, as a non-thermal ablation method, has attracted extensive attention from the academic community. IRE technology transmits a series of short and strong electrical pulses through electrode needles directly implanted or placed around the diseased tissue, forming an electric field between the electrodes, and changing the transmembrane potential of the cell membrane in the diseased cells. Once the transmembrane potential reaches the threshold, Electroporation will be formed on the cell membrane, and as the electric field continues to increase, it will lead to irreversible electroporation of the cell membrane...
