Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings. However, those skilled in the art know that the present invention is not limited to the drawings and the following embodiments.

[0045] As used herein, the term "comprising" and its variations may be understood as open-ended terms meaning "including but not limited to". The term "based on" may be understood as "based at least in part on". The term "one embodiment" can be read as "at least one embodiment". The term "another embodiment" may be understood as "at least one other embodiment".

[0046]As mentioned above, since patients have different lesions, and needle placement generally depends on the doctor's experience and is highly subjective, the needle placement scheme adopted may not be able to completely ablate the p...

Abstract

The present invention relates to an electrode pinning device and method based on a lesion area, wherein the device includes: a set acquisition module for acquiring a set of candidate pinning points based on the original lesion area; a factor acquisition module for acquiring the candidate points based on the current lesion area The effective evaluation factor of the ablation needle group composed of any two candidate needle placement points in the needle placement point set, and record the ablation needle group corresponding to the maximum effective evaluation factor; the area update module is used for the ablation needle group corresponding to the maximum effective evaluation factor The formed ablation area, updating the current lesion area for the acquisition of effective evaluation factors and recording its corresponding ablation needle group, and the operation of updating the current lesion area continues until the current lesion area is zero; and, the needle group The integration module is used to integrate all recorded ablation needle groups as the optimal needle arrangement combination. The solution of the embodiment of the present invention can achieve the effect of completely ablation of the lesion area, and at the same time, the number of needles is the least and the additional ablation area is the smallest.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an electrode needle clothing device and method based on a lesion area. Background technique [0002] Studies have found that cancer has become one of the major diseases that endanger human health. The use of pulsed electric field ablation technology to ablate the lesion area has made gratifying progress. When performing ablation treatment, when the lesion area is large, only two electrode needles (that is, a group of electrode needles) cannot achieve complete ablation. Multiple electrode needles, and then ablation is performed in groups of two electrode needles. For the case of combined ablation with multiple electrode needles, there are currently two traditional needle placement schemes for lesion ablation: one is the surrounding center needle placement scheme, which is mainly suitable for larger lesions, specifically: one needle placement in the center of ...
