Cranial orthosis with safety stop and method

摘要

A cranial orthosis includes a helmet member that can be expanded for mounting on a patient's head and subsequently contracted to be operatively positioned to permit the interior surface to reconfigure the patient's head to the desired shape is provided. The helmet member can have a split with a safety stop unit positioned on the helmet member to provide a safety limit to the adjustment against the patient's head. A safety stop unit can include a bellows member, a stop unit mounted on a flange extending from the helmet and a stop unit including a plurality of nestling components that can relatively move to permit the expansion step while nestling to a fixed position in a stacked configuration to provide a stop position against further closure of the cranial orthosis to protect the patient.
