Artificial cervical intervertebral disc with ultrahigh activity type chamfering U-shaped structure

The invention provides an artificial cervical intervertebral disc with an ultrahigh activity type chamfering U-shaped structure. The artificial cervical intervertebral disc comprises an artificial cervical intervertebral disc body which is prepared from titanium alloy. The artificial cervical intervertebral disc is characterized in that the part in which an upper end plate and the lower end plate of the artificial cervical intervertebral disc body is of a chamfering reversed U-shaped noncontact elastic structure; the physiological curvature of the upper end plate and the lower end plate protruding towards of the artificial cervical intervertebral disc body is 3 to 6 degrees; the front ends of the upper end plate and the lower end plate are fixed through bolts; the front edges of the upper end plate and the lower end plate have arc-shaped appearances similar to human vertebration; two rows of reversed teeth for stopping backing are respectively arranged in the outer surfaces of the upper end plate and the lower end plate; the elasticity modulus of the artificial cervical intervertebral disc body is 45 to 80GPa, and the yield strength is more than 620MPa. The artificial cervical intervertebral disc meets the requirements on long service life and fatigue resistance; the mobility of operated sections of a patient can be 80 to 100% of that of normal human body.
