Computer-assisted puncture path planning method and device for craniocerebral puncture surgery and storage medium

Abstract

The invention relates to a computer-aided puncture path planning method and device for a craniocerebral puncture operation and a storage medium. The method mainly comprises the following steps: adding the geometric morphology of a focus target area into a category to be considered in path planning, performing optimization adjustment by combining information input of clinical experts, and finally obtaining an accurate puncture path in an alternative puncture path area. Meanwhile, the invention further provides a three-dimensional puncture early warning scheme of preoperative planning and intraoperative navigation. The craniocerebral puncture operation covering effect can be improved, for example, the effectiveness of biopsy sampling is improved, or the efficiency of puncture medicine delivery and drainage processes is improved.

Description

technical field [0001] The present invention relates to the technical field of computer-aided operation path planning, in particular to a computer-aided puncture path planning method, device and storage medium for craniocerebral puncture. Background technique [0002] Before craniocerebral puncture, the puncture path needs to be planned. The puncture path is formed by the starting point on the skin surface and the target point at the lesion. [0003] At present, the planning of the puncture path is a difficult point. This is due to the complex functional structure of the brain, which includes important functional structural objects such as arteries, nerve fibers, myelin, and cerebral cortex (gray matter). It is difficult to reflect this three-dimensional spatial relationship on two-dimensional tomographic images, so the traditional method of relying only on two-dimensional tomographic image information to assist preoperative puncture path planning is not rigorous enough,...

AI Technical Summary

Problems solved by technology

It is difficult to reflect this three-dimensional spatial relationship on two-dimensional tomographic images, so the traditional 2D tomographic image information to assist preoperative puncture path planning is not rigorous enough, and it is difficult to select a puncture starting point that meets clinical requirements

The planned route is easy to misjudge and cause damage to arteries, nerve fibers, etc.

Moreover, the selection of the puncture path generally depends on the doctor's clinical experience, which has the following disadvantages: the doctor may lack a quantitative understanding of the geometric shape of the lesion area, thus ignoring the influence of the geometric shape of the lesion on the effect of craniocerebral puncture, and then Can affect the success rate of biopsy puncture or the efficiency of hematoma drainage
