Flexible maxillo-mandibular fixation device

摘要

A system for achieving maxillo-mandibular fixation includes a bone fixation device including a bone fixation body formed from a plurality of links. The links define corresponding crests and valleys so as to impart flexibility into the bone fixation body. Thus, the bone fixation body can be aligned with the dental arch of the mandible and maxilla as necessary, and subsequently fastened to the underlying bone. Each bone fixation device includes at least one securement location on the fixation body that can attach to a securement device, such that the securement device fixes or stabilizes the mandible and the maxilla with respect to each other.

主权项

1. A maxillo-mandibular fixation kit comprising:
a first bone fixation body including a first plurality of interconnected links adjacent to each other along a respective first longitudinal direction between opposed first and second ends of the first bone fixation body, the first plurality of links defining a plurality of crests and an opposed plurality of valleys configured so that the first bone fixation body has an undulating shape, the first bone fixation body including 1) a first plurality of bone attachment locations, each of the first plurality of bone attachment locations defined at a respective one of the first plurality of valleys, and 2) a first plurality of securement locations, each of the first plurality of securement locations defined at a respective one of the first plurality of crests, wherein the links of the first plurality of links are flexible in the longitudinal direction such that a length of the first bone fixation body defined from the first end to the second end is adjustable along the longitudinal direction; and a second bone fixation body including a second plurality of interconnected links extending in a respective second longitudinal direction between opposed first and second ends of the second bone fixation body, the second plurality of links defining a plurality of crests, a plurality of valleys, a second plurality of bone attachment locations, and a second plurality of securement locations, wherein the links of the second plurality of links are flexible in the second longitudinal direction; wherein the first and second pluralities of securement locations are configured to engage with a securement device that fixes the first bone fixation body with respect to the second bone fixation body.
