    摘要: An expandable implant device (100, 300, 600) for insertion between two vertebrae (400) is disclosed. The device (100, 300, 600) has a center body (10) one or more lift bodies (20, 40) and an external retaining band (60). The external retaining band (60) holds the sides (22, 42) of the one or more lift bodies (20, 40). The center body (10) has ramp surfaces (11) having a plurality or sets of ramps (11) sloped for allowing upward movement of the one or more lift bodies (20, 40). The sides (22, 42) have complimentary ramp surfaces that fit onto the ramps (11) of the center body (10). The height of the device (100, 300, 600) is increased by upward movement or downward movement or both of the one or more lift bodies (20, 40) driven by the lengthwise movement of the center body (10).

    摘要: The present invention provides a unique way to provide a self-locking screw opening that has no separate parts. The self-locking feature (20) is formed in the wall (11) of the screw receiver opening (12) and automatically locks a screw (100) from backing out. During insertion of the screw (100) into bone, the screw head (110) passes one or more, preferably two nubs (20) or one or more projections (20) formed into the surface wall (11) of the receiver opening (12), and as the screw (100) is threaded into the bone, the screw head (110) contacts the nubs (20) or projection (20) and the screw (100) is deflected slightly in a direction opposite the nubs (20) or projection (20) allowing the screw head (110) to pass by the nubs (20) or projection (20) locking the screw (100) from backing out.
