DYNAMIC DECOMPRESSIVE CRANIOTOMY FIXATION DEVICES AND RELATED METHODS

摘要

The present disclosure provides dynamic cranial fixation devices and related methods for attaching a resected bone portion(s), or a bone flap, to the skull in such a manner that allows for brain swelling to occur with minimal constraint following a craniotomy or craniectomy. The present disclosure provides dynamic cranial fixation devices and related methods that provide outward movement of the bone flap as the brain swells underneath the bone flap to prevent or reduce a rise in the intracranial pressure. Once the brain swelling resolves, the dynamic cranial fixation devices and related methods of the present disclosure allow the bone flap to return to its original position (before resection) without further surgery, implantation or the like. Once the bone flap return to its original position (or substantially similar position), the bone flap may fuse with the neighboring bone(s), potentially with the assistance of one or more fusion aid.

主权项

1. A dynamic cranial fixation device for coupling a bone flap and a cranium, comprising:
a connector member; a first wing member with at least a first aperture configured to accept a bone attachment member therethrough to fix the first wing member to one of a bone flap and a cranium, the first wing member extending from a first side of the connector member; and a second wing member with at least a first aperture configured to accept a bone attachment member therethrough to fix the second wing member to the other of the bone flap and the cranium as compared to the first wing member, the second wing member extending from a second side of the connector member, and wherein the connector member includes an elongated aperture or a pair of pin members, and wherein each of the first and second wing members include the other of the elongated aperture or one of the pin members of the pair of pin members as compared to the connector member, and wherein the pin members are provided within the elongated aperture to movably couple the first and second wing members with the connector member.
