1. Laminar Shelf-type Plate:
   The laminar shelf structure makes the fixation of the plate easier and more reliable.
   The support design of the plate can effectively expand the volume of the spinal canal.
   The support foot frame design provides more reliable stress support when fixing the lateral mass.
   The support and fixation of the plate can effectively maintain the inherent stability.
