Osteoporosis is a common bone disease that often leads to difficulty in vertebrae revision. Traditional pedicle screws are often complicated to operate and have poor visibility during implantation. A new detachable pedicle screw is needed to improve the revision effect. The aim of this study was to design a new detachable pedicle screw based on medical optical imaging to improve the outcome of vertebral revision in osteoporosis, and to improve operational feasibility and visibility. In this study, the parameters related to the degree of osteoporosis were obtained by optical imaging detection of the osteoporotic vertebral body. Then a new detachable pedicle screw was designed according to the test results to improve the effect of vertebral body revision. By preparing and optimizing the material and structure of the screw, it is ensured that it has sufficient mechanical strength and stability. Finally, the visibility and operability of the improved screw during implantation were verified by medical optical imaging. Compared with traditional screws, the new detachable pedicle screw can improve the vertebral body revision in the case of osteoporosis. The optical imaging test results show that the new screw has good visibility and maneuverability, providing more accurate guidance and positioning for the vertebral body revision operation.

基于医学光学影像检查的新型可脱式椎弓根螺钉设计改善骨质疏松增强椎体翻修效果

骨质疏松症是一种常见的骨病，常常导致椎骨翻修困难。传统的椎弓根螺钉往往操作复杂且植入过程中可视性较差。需要一种新型的可拆卸椎弓根螺钉来提高修复效果。本研究的目的是设计一种基于医学光学成像的新型可拆卸椎弓根螺钉，以改善骨质疏松症椎体翻修的效果，并提高手术可行性和可视性。本研究通过光学成像检测骨质疏松椎体获得与骨质疏松程度相关的参数。然后根据试验结果设计了新型可拆卸椎弓根螺钉，以提高椎体翻修效果。通过制备和优化螺杆的材料和结构，保证其具有足够的机械强度和稳定性。最后，通过医学光学成像验证了改进后的螺钉在植入过程中的可视性和可操作性。与传统螺钉相比，新型可拆卸椎弓根螺钉可以改善骨质疏松情况下的椎体修正。光学成像测试结果表明，新型螺钉具有良好的可视性和可操作性，为椎体翻修手术提供更准确的引导和定位。
