Description

  The present invention relates to a skull treatment device.

  The skull of a child in development is divided into a plurality of borders with a cranial suture line, and the skull grows in response to the brain becoming larger (swelling). The opposite ends of the joints extend in the direction of union (stick), and the skull also becomes larger.) When the development of the brain is completed, this cranial suture line unites.

  By the way, by the time the development of the brain is completed, part or all of the cranial suture line is fused, and the development of the brain proceeds in a state where the cranial suture is fused. There is an early fusion of the skull that causes the skull to deform.

  Until now, the following devices (hereinafter, conventional examples) have been proposed as skull treatment devices for treating this early skull fusion.

  In this conventional example, as shown in FIG. 15, a fastening body 134 fastened to each skull piece 133 from which a fused portion of the skull piece 133 is cut off, and a fastening body 134 fastened to each skull piece 133.
