Abstract

The invention provides a cervical vertebra prosthesis, which comprises: a solid layer, wherein the solid layer comprises a front side plate and a rear side plate which are connected with each other, the front side plate and the rear side plate jointly define a containing cavity, the front side plate is of an arc-shaped structure, and the axis of the front side plate extends in the vertical direction; and a porous layer filled in the containing cavity, wherein the cervical vertebra prosthesis is provided with a first bone grafting hole, the first bone grafting hole extends in the vertical direction and penetrates through the upper end surface and the lower end surface of the porous layer, the cervical vertebra prosthesis is further provided with a second bone grafting hole, and the second bone grafting hole penetrates through the front side plate and extends into the porous layer. Through the technical scheme provided by the invention, the problem that the bone grafting quantity cannot be increased on the premise of meeting the structural strength of the cervical vertebra prosthesis in the related technology can be solved.

Description

technical field [0001] The invention relates to the technical field of prostheses, in particular to a cervical vertebra prosthesis. Background technique [0002] Cervical spondylosis is one of the common diseases in humans. Anterior cervical subtotal resection and fusion is a common surgical method for the treatment of cervical spondylosis. This surgery implants cervical prostheses in the diseased vertebral body to achieve the reconstruction of cervical vertebrae. purpose of the paragraph. [0003] In related technologies, the cervical prosthesis is composed of a titanium cage and a cervical plate. Due to the design of the titanium cage and the cervical plate, the cervical prosthesis cannot increase the amount of bone graft while satisfying the structural strength. Contents of the invention [0004] The invention provides a cervical prosthesis to solve the problem that the cervical prosthesis in the related art cannot increase the amount of bone graft on the premise of sa...
