Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like figure 1 and figure 2 , the cervical fusion device of the present invention is implanted into the damaged site of the cervical spine. The cervical fusion device is processed from cortical bone into a square or plate-shaped bone graft block 1 that meets the clinical requirements for cervical bone grafting. According to the characteristics of the cervical vertebral body and cervical bone graft surgery to maintain the physiological characteristics of the lordosis of the cervical spine, figure 1 Among them, the bone graft block 1 has a circular arc-shaped end surface, where b is set as the end, and a is set as the front end. The two groups of opposite sides of t...

Abstract

The invention relates to the bone grafting technical field, and discloses a cervical vertebral fusion cage and a fabrication method of the cervical vertebral fusion cage. In the invention, the cervical vertebral fusion cage is a quadrate or board-shaped bone graft made by processing an allogenic cortical cone, wherein the bone graft is provided with an instrument clamping part and a hollowed chamber having a filling port; the instrument clamping part is arranged at one end of the bone graft; and two groups of opposite sides of the bone graft respectively form certain included angles. The cervical vertebral fusion cage is the quadrate or board-shaped bone graft which meets the requirement of clinical bone grafting; moreover, the bone graft is provided with the hollowed chamber to fill autogenous bone, therefore the cervical vertebral fusion cage is easy to be degraded by human body with good fusion effect, and the rejection can be greatly reduced. Furthermore, disinfection process is carried out to the cervical vertebral fusion cage to reduce the risk caused by viruses or microorganisms which spread disease to the cortical bone, as well as various immunological rejection risks.

Description

technical field [0001] The invention relates to the technical field of bone grafting, in particular to a cervical fusion device processed by physical and chemical methods and a manufacturing method thereof. Background technique [0002] At present, the products used for cervical fusion and fixation mainly include metal materials, polymers and biomaterials. The advantages of metal materials and polymer materials are stable strength, which can support and maintain the pressure and height between the vertebral bodies, but the main disadvantage is that they remain in the body for a long time as foreign bodies, causing side effects such as foreign body stimulation, requiring a second operation to remove them. It is taken out and not convenient enough to use. [0003] An ideal vertebral fusion cage should have perfect mechanical properties and biological activity. Allograft bone ring is a commonly used clinical method as implantation material for cervical intervertebral fusion. ...
