Title:

MIDFACE DISTRACTOR

Document Type and Number:

WIPO Patent Application WO/2005/107620

Kind Code:

A3

Abstract:

An external midface distractor is disclosed for attachment to the bones of a patient's cranium and midface region for performing an osteogenesis procedure to gradually lengthen a portion of the craniofacial skeleton. The midface distractor generally includes an external halo assembly for engaging the patient's cranium, a central adjustment assembly, a vertical central rod, at least one horizontal cross piece assembly including at least one distraction screw, and at least one bone engaging portion which is mounted to the targeted facial bone to be distracted. The midface distractor may also include various individual adjustment mechanisms that provide surgeons greater and more precise control over the distraction vector than is available with current devices. That is, the midface distractor may provide surgeons with additional anterior-posterior and medial-lateral adjustments, thus permitting surgeons to more precisely and accurately control the direction of distraction. The midface distractor may also permit surgeons to easily and accurately alter the direction of distraction after the distraction procedure has commenced thereby providing surgeons the ability to readjust the ultimate vector of distraction anytime during the procedure, as necessary.
