FIELD: medicine.
SUBSTANCE: invention refers to medicine, particularly to maxillofacial surgery and traumatology. Device for fixation of fragments of lower jaw includes assembly of pinned fixing units arranged one after another on rod connecting fixing units into assembly. Each fixing unit comprises a support body mounted with possibility of movement along the rod, and an additional body equipped with spokes. Support body of each fixing unit has a first flat contact surface for contact with additional body of this fixing unit. Additional body has the second flat contact surface intended for contact with the first flat contact surface of the support body of this fixing unit. Fixing device is configured to compress the first and second flat contact surfaces in the fixing position. At least one pair of adjacent fixing assemblies on each additional body is equipped with a post with a through transverse hole with a lead screw arranged in these holes, which in one through transverse hole with smooth surface is mounted with possibility of rotation around vertical axis of post, and in the other through transverse hole it is mounted with possibility of interaction with screw thread made in it.
EFFECT: simplified design of external fixation apparatus with possibility of fixation and reduction of lower jaw fragments in physiological relation to upper jaw.
