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...

The invention relates to an electrode needle distribution device and method based on a focus region. The device comprises a set acquisition module used for acquiring a candidate needle distribution point set based on an original focus region, a factor acquisition module used for acquiring an effective evaluation factor of an ablation needle group consisting of any two candidate needle distributionpoints in the candidate needle distribution point set based on a current focus region and recording the ablation needle groups corresponding to the maximum effective evaluation factors, an area updating module used for updating the current focus region based on an ablation region formed by the ablation needle groups corresponding to the maximum effective evaluation factors to enable the operationof acquiring the effective evaluation factors, recording the ablation needle groups corresponding to the effective evaluation factors and updating the current focus region to be continuously executeduntil the current focus region is zero, and a needle group integration module used for integrating all the recorded ablation needle groups to serve as an optimal needle distribution combination. According to the scheme of the embodiment of the invention, the effect of completely ablating the focus region can be achieved, meanwhile the needle number is minimum, and the additional ablation area isminimum.
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 ...
