Abstract:
The bionic dislocation-proof artificial lumbar vertebrae and disc complex comprises vertebral body components, intervertebral disc components and screws; the vertebral body components comprise an oval column; the intervertebral disc components comprise L-shaped arc plates and composite pads, the L-shaped arc plates comprise bottom plates, lateral plate and the raised column; end of the raised column is the ball shell with two raised arc; the composite pad is connected to the groove on the oval column; the ball shell and the composite ball form the ball and socket joint. The present invention replaces the removed vertebrae and adjacent discs and maintains the rotation, flexion and extension and buffer function, which ensures the stability and mobility of the lumbar spine after surgery. The present invention better resembles the normal physiology.

Claim (Index 10):
The bionic dislocation-proof artificial lumbar vertebrae and disc complex, as recited in  claim 1 , wherein the oval column ( 1 ), the L-shaped arc plate ( 3 ) and the composite pad ( 4 ) are integrated into one body; the oval column ( 1 ) and the L-shaped arc plate ( 3 ) adopt medical titanium alloy; the composite pad ( 4 ) adopts UHMWPE (ultra-high molecular weight polyethylene) or PEEK (polyetheretherketone); hydroxylapatite coating is applied on a contact area of the L-shaped arc plate ( 3 ) and bones and a flank of the oval column ( 1 ).
