Abstract

The invention provides a centrum extension device which comprises a centrum component. The centrum component comprises an upper centrum, a lower centrum and a driving structure positioned between theupper centrum and the lower centrum and capable of driving the upper centrum and / or the lower centrum to move in a first direction, and the first direction of a length direction of the centrum component. By mounting a driving structure between the upper centrum and the lower centrum, the upper centrum and / or the lower centrum is enabled to move in the length direction of the centrum component, sothat different length needs on the centrum component can be met; when the centrum component is applied to spines of children, growth of the children can be met by adjusting length of the centrum component.

Description

Technical field [0001] This application relates to the medical field, and specifically to a vertebral body elongation device. Background technique [0002] Patients with primary spinal vertebral tumors, some localized metastatic tumors, severely comminuted vertebral fractures, and some spinal compression fractures that have not undergone initial treatment with neurological dysfunction and obvious angular deformities often require vertebral resection Or subtotal resection. The stability of the spine after removal of the vertebral body will undoubtedly be destroyed, and reconstruction of the structure and function of the spine is a necessary condition for maintaining the normal biomechanical stability of the spine. [0003] At present, products on the market have passed biomechanical testing and clinical applications, and found that there are some problems in the axial rotation of the artificial vertebral body, and the joint between the upper and lower end faces of the artificial ve...
