Abstract
The invention concerns an artificial centrum made by polyether ether ketone or carbon fiber reinforcement polyether ether ketone. The weight ratio of the carbon fiber in the said carbon fiber reinforcement polyether ether ketone is 0-40%. The artificial centrum is of hollow columnar structure, the size and the shape of the cross section is similar to that of the cross section of the human body corresponded centrum. The angle of the upper and lower end face of the said artificial centrum with the centrum cross section is 0-10 DEG. Compared with the prior arts, it has advantages of favorable compatibility with the human body, strong adhesion force and X-ray permittance.
Description
Technical field
The present invention relates to the artificial bone field of medical science category, relate in particular to a kind of artificial vertebral body.
Background technology
At present, due to illness it is damaged to become the joint (or major part of vertebral body) that (based on tumor) or wound cause for cervical vertebra, thoracic vertebra or lumbar vertebra patient clinically, comprise the vertebra joint that due to illness becomes excision, traditional operation is to take from the body ilium to transplant, or take from the body ilium and transplant and to be aided with steel plate simultaneously, but this therapy not only increases patient's misery, and the height of vertebra joint is lost easily.And the normal pressure artificial vertebral body can recover the normal height of pathological changes vertebral body, and the fusion that helps the vertebra joint later stage is with stable; Existing artificial vertebral body adopts metal materials such as titanium alloy to make more, the common trait of metal material is that its elastic modelling quantity is far longer than the vertebral body bone, bone and vertebral body interface easily produce big stress, be unfavorable for the fusion of bone and material, and metal material X line is light tight, can't merge situation with conventional X sheet inspection.
Summary of the invention
Purpose of the present invention is exactly that a kind of, strong adhesion good with human compatibility, the artificial vertebral body of X-ray thoroughly are provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions: a kind of artificial vertebral body, it is characterized in that, this artificial vertebral body is made by polyether-ether-ketone or carbon fiber reinforced polyether-ether-ketone, the shared weight ratio of carbon fiber is 0～40% in the described carbon fiber reinforced polyether-ether-ketone, this artificial vertebral body is the open column shape structure, the cross section of the size of its cross section, shape and the corresponding vertebral body of human body is close, and described artificial vertebral body upper and lower end face and cylinder cross section are 0～10 ° of angle.
Described artificial vertebral body side is distributed with aperture.
Described artificial vertebral body upper and lower end face respectively is provided with 2～4 thorn angles.
Described artificial vertebral body upper and lower end face is plane or curved surface.
Normal person's cortical bone elastic modelling quantity is 12～25GPa, the carbon fiber reinforced polyether-ether-ketone can be by the adjusting of carbon fiber ratio, making its elastic modelling quantity is 3.5～25GPa, and compare with it, the elastic modelling quantity of titanium alloy is 300GPa, and therefore, carbon fiber reinforced polyether-ether-ketone rigidity and human body are close, be difficult for producing stress concentration, biomechanical stability is good.
Compared with prior art, the present invention has following characteristics:
1. the present invention adopts polyether-ether-ketone or carbon fiber reinforced polyether-ether-ketone to make, and not only good biocompatibility, and intensity and elastic modelling quantity all meet the requirement of human vertebra biomechanics, helps the bone fusion in interface combination and later stage.
2. by the intermediary hollow part of artificial vertebral body, can place broken bone and the fusion of help performing the operation later stage artificial vertebral body and vertebra internode with stablize.
3. use artificial vertebral body can recover the normal height of pathological changes vertebral body, recover the sagittal physiological curve of normal spinal column.
4. vertebral body upper and lower end face and artificial vertebral body cross section meet people's physiological structure at an angle.
5. the thorn angle of artificial vertebral body upper and lower end face guarantees that vertebral body and cortical bone have enough adhesive force.
6. material X line printing opacity helps following up a case by regular visits to and estimating of postoperative.
