Definitions

  • the present invention belongs to the field of medical devices, and in particular, to a three-dimensional simulation surgical nail placement planning method and a surgical simulator.
  • Normal human spine has 32 ⁇ 34 spine bones: 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 vertebrae and 3 ⁇ 5 tail vertebrae. There are 23 discs and 134 joints. The side of the spine is "S" shaped and the front is in a straight line.
  • the screw is moved in the direction of the nail path so that the screw is in the actual surgical position, and the screw planning is completed.
  • the method for planning a three-dimensional simulated surgical staple provided by the first embodiment of the present invention includes the following steps:
  • the three cross-sectional views include a sagittal plane, a coronal plane, and a horizontal plane.
  • the nail path of the screw is the intersection of the transverse section (initially horizontal) and the anterior and posterior section (initial sagittal plane). In this way, by adjusting the cutting plane, the details of the nail path can be observed, so that the planning of the nailing is more precise.
  • the cutting plane is adjusted, and the nail insertion point and the nail insertion direction are planned.
  • the entry point is the intersection of the screw along the nail path from the outside to the bone tissue of the three-dimensional model and the nail contact with the bone tissue.
  • the direction of the nail is from the point of the nail to the direction of the nail. This way, you can add screws directly.
  • the planned screw is superimposed with the three-dimensional model as an integral three-dimensional model to participate in the planning of the next screw. This allows for better planning of each screw to avoid mutual interference.

Abstract

L'invention concerne un procédé de planification de placement de vis pour une intervention simulée tridimensionnelle, et un simulateur d'intervention chirurgicale, qui s'appliquent au domaine des instruments médicaux. Le procédé de planification consiste à : réaliser une modélisation tridimensionnelle selon une image CT de colonne vertébrale reçue de façon à générer un modèle tridimensionnel (S101) ; générer trois images de plan de coupe selon le modèle tridimensionnel (S102) ; afficher le modèle tridimensionnel et les trois images de plan de coupe du modèle tridimensionnel (S103) ; ajuster les positions et les directions de coupe de plans de coupe de façon à observer intuitivement une condition de plan de coupe d'une colonne vertébrale (S104) ; déterminer un canal de vis d'une vis au moyen d'une ligne d'intersection de plans de plans de coupe dans deux directions (S105) ; ajouter la vis au canal de vis déterminé (S106) ; et déplacer la vis dans la direction du canal de vis pour positionner la vis dans une position de fonctionnement effectif, achevant ainsi la planification de la vis (S107). Le procédé de planification est simple et pratique, peut planifier un canal de vis plus précisément, et permet un placement de vis plus sûr et plus fiable.
