摘要： A driver device (hexalobe or otherwise) that includes a handle portion, an elongate shaft portion, and an end portion that includes a screw engagement portion and a split manufactured offset from the central axis of the end portion and/or the screw engagement portion, forming two asymmetric halves of the end portion and/or screw engagement portion. This screw engagement portion is slightly oversized relative to the corresponding tool engagement recess of the locking cap, set screw, or bone screw. Thus, when the screw engagement portion is pressed into the corresponding tool engagement recess of the locking cap, set screw, or bone screw, the split manufactured offset from the central axis of the end portion and/or the screw engagement portion allows the screw engagement portion to compress slightly, creating a friction fit between the screw engagement portion and the corresponding tool engagement recess of the locking cap, set screw, or bone screw.

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.”
