Abstract:
1. A distractor device for distraction of a mandible divided at an osteotomy site between first and second molar teeth into an anterior segment and a posterior segment, the distractor device comprising: an elongate body having a longitudinal groove extending at least partly along the length of the body; a first fixing member having a first longitudinal axis, the first fixing member comprising: a second fixing member having a second longitudinal axis offset from the first longitudinal axis, the second fixing member comprising: an activator member engaging with the elongate body, wherein at least the end portion of the first fixing member is adjustable along the longitudinal groove of the elongate body in an anterior direction by movement of the activator member relative to the body to distract the anterior segment in use; wherein the first fixing member and the second fixing member are spaced from the elongate body at different average lengths; and wherein positioning of the mounting portion of the first and second fixing members is effective so as not to crowd the osteotomy site, and allow improved displacement of the first fixing member relative to the second fixing member for incremental lengthening of the mandible through distraction of the anterior segment by the activation member.
