▎ 摘　　要

NOVELTY - Cervical anterior bone plate made of medical carbon fiber reinforced polyetheretherketone material, comprises a plate body (1), a screw (2) and a locking nail (3). The plate surface of the plate body is symmetrically distributed with a screw hole. The screw is installed in the screw hole. The screw and the head radius of the screw is greater than the aperture of the hole. A locking hole is provided between two adjacent screw holes, and the locking nail is rotatably mounted with the locking hole. An edge of the head of the locking nails is overlapped with a head of an adjacent bolt, and forms a superposition area. The head circumference side of the lock nail is provided with a concave arc on the head circumference. The shape of the arc is the same with the overlapping area. USE - Cervical vertebra anterior bone fracture plate made of medical carbon fiber reinforced polyetheretherketone material for use in medical appliance field. ADVANTAGE - The crown face and the sagittal plane of the plate body are provided with a certain radian to adapt to the physiological curvature of the vertebral body. The special structure of the bolt and the locking nail ensures the screw hole can freely pass through the part of bolt screw thread but the head of bolt cannot pass through, at the same time. The locking nail can be easily rotated but cannot be pulled out, and the action is to prevent the bolt from exiting. The bone fracture plate can not exit when the sterility is loose. The plate body is made of medical carbon fiber reinforced polyether-ether-ketone material, and uses nano-scale oxidation to graphene the surface of the carbon fiber, and then using modified carbon fiber-reinforced polyetheretherketone, and further improving the mechanical property of the DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the cervical vertebra anterior bone fracture plate made of medical carbon fiber reinforced polyetheretherketone material for use in medical appliance field. 1Plate body 2Screw 3Locking nail
