Reconstruction method and device for skull defect structure and electronic equipment

Abstract

The invention provides a reconstruction method and device for a skull defect structure and electronic equipment, and relates to the technical field of skull repair, the method comprises the followingsteps: obtaining three-dimensional image information of a pre-operation complete skull, defect edge contour information of an intraoperative defect skull and a main visual angle direction; rotating and projecting a first point set in the three-dimensional image information and a second point set in the defect edge contour information according to the main view angle direction, a preset rotating direction and a preset projection plane to obtain a first plane point set and a second plane point set; obtaining a target point set corresponding to the defected skull according to the first plane point set and the second plane point set; and performing three-dimensional reconstruction of the model structure on the target point set to obtain a target skull defect structure. A doctor does not need to manually segment the skull defect structure, errors caused by manual operation are reduced, and the skull defect structure reconstruction accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of skull repair, in particular to a reconstruction method, device and electronic equipment for a skull defect structure. Background technique [0002] The main steps of neurosurgery are surgical approach, lesion resection and skull base reconstruction. The lesion area in the brain is complex, often adjacent to or invading important neurovascular. In order to minimize the trauma of the patient, it is necessary to choose a suitable surgical approach to minimize the damage caused by the surgical approach. The quality of skull base reconstruction directly affects the prognosis of patients: insufficient skull closure will lead to common complications; skull defects, soft tissue and dura mater defects may lead to postoperative cerebrospinal fluid leakage, encephalocele, and intracranial and intracranial infections. Therefore, choosing the surgical approach with the least damage and ensuring good skull closure ar...

AI Technical Summary

Problems solved by technology

Since manual operation will inevitably bring certain errors, and there are certain operational risks during the surgical operation, it cannot be guaranteed that the skull defect caused by the surgical approach is completely consistent with the preoperative estimation, so the reconstruction method obtained The structure of the skull defect may not match the actual shape of the skull defect, resulting in inaccurate reconstruction of the skull defect structure
