This invention discloses a drilling path planning method, storage medium, and device for cochlear implantation, belonging to the field of path planning technology in cochlear implantation. This invention solves the problems of low efficiency and easy introduction of path deviation in existing path planning methods. The invention preprocesses preoperative three-dimensional CT images and integrates anatomical structural models to extract three-dimensional spatial geometric information of key tissues within the temporal bone, including the facial nerve and cochlea. Subsequently, combined with prior medical knowledge, the drilling path for the cochlear implant electrode is automatically planned in three-dimensional space to minimize damage to key nerves and ensure surgical safety. The path planning method of this invention is applicable to cochlear implantation surgery assisted by medical robots, significantly reducing reliance on the doctor's subjective judgment, improving the individualized adaptability and efficiency of path design, and effectively avoiding path deviation caused by human subjective judgment. This invention can be applied to path planning in cochlear implantation surgery.
