Abstract
A vertebral end plate processing device includes a handle, a vertical opening mechanism, a horizontal expansion mechanism and a processing mechanism. When the processing device is in a non-working state, the vertical opening mechanism and the horizontal expansion mechanism maintain a contracted state, and a processing portion is located within a vertical space between opening members. When the processing device is in a working state, the opening members of the vertical opening mechanism are in contact with a bone surface of a vertebral body and vertically open same. An arc-shaped expansion block of the horizontal expansion mechanism drives a conveying member for horizontal expansion so that the processing portion is horizontally removed from the vertical space of the opening members and is in contact with the bone surface of the vertebral body. A control portion controls the conveying member to move.
