Title: MANDIBULAR DISTRACTOR
Abstract:
The present invention relates to a mandibular distractor comprising two connected and cooperating distension arms (1, 2), each of which is equipped with one or more attachment means (3, 3') for attaching to the jaw of an individual. Advantageously, the connection between the distension arms (1, 2) is made by means of a system comprising a cap (7) included in one of the arms (1) and a coaxial rod (8) included in the other arm (2), wherein the cap (7) and rod (8) are configured to move relatively in a longitudinal manner, causing the distension of the ascending ramus (4) of the jaw in relation to the main body (5) of the jaw during use. The distractor also comprises an internal traction system (9) housed in the cap (7) and connected to the rod (8) by means of a transmission means (10) designed to transmit the movement generated by the actuating system (9) to the rod (8), thereby causing mandibular distension.
