Claims

[Scope of utility model registration request]

It is equipped with a cervical orthosis body whose inner diameter and width of installation can be varied to accommodate cervical vertebrae of various sizes, and guide elongated holes are provided on both sides of the cervical orthosis body, and both ends of the chin rest member are provided with long guide holes. The guide is attached to the elongated guide hole via a mounting shaft so as to be rotatable in the vertical direction and movable in the front-back direction, an engagement protrusion is provided on the upper front surface of the cervical spine brace body, and an engagement hole is provided on the lower front surface of the chin rest member. By inserting and engaging the engagement protrusion into the engagement hole with the attachment shaft positioned at the rear end of the guide elongated hole, the chin rest member is attached to the front surface of the cervical brace main body. fixed, and the chin rest member supports the lower jaw in a fixed state; on the other hand, the engagement protrusion and the engagement hole are disengaged, and the mounting shaft is positioned at the front end of the guide elongated hole. This is a cervical spine fixation device in which the chin rest member does not fix the lower jaw, but allows the lower jaw to move freely.
