Abstract: A head fixation device includes a rocker arm assembly containing one or more stabilizing features. The rocker arm is rotatably adjustable about a longitudinal axis of the rocker arm assembly to any rotational position in a non-stepped fashion. The rocker arm assembly is removable from the head fixation device for easy of cleaning. A lever of the rocker arm assembly translates a shaft and includes eccentric features to provide a camming action for moving locking features of the rocker arm assembly to an unlocked state such that the rocker arm can be rotationally adjusted.

Abstract: A method or process for making one or more components of a head fixation device includes preforming, molding, and finishing subprocesses. The preforming subprocess includes placing fibers onto a substrate to orient the fibers parallel to a flux of force that the component is expected to experience in use. The fiber layers are combined and can be draped over an optional core before being molded to combine the assembly with a molding material. The resultant molded preform undergoes a finishing subprocess that can include smoothing the component to remove any burrs or sharp edges from the molding subprocess.
