摘要： A surgical plate device that incorporates a screw locking mechanism in each screw hole by which the surgical plate device is affixed to a bony segment. The screw locking mechanism includes a tab structure emanating from an interior portion (or either surface) of the surgical plate that is biased into a portion of the corresponding screw hole. When a screw is inserted into the screw hole, the head of the screw temporarily biases the tab structure out of the screw hole, until the head of the screw passes below the plane of the tab structure, at which point the tab structure rebounds into the previously occupied portion of the screw hole, thereby covering a portion of the head of the screw and preventing it from “backing out.”
