DEVICE FOR JAW FRACTURES TREATMENT

摘要

FIELD: medicine.;SUBSTANCE: device for lower jaw fractures treatment includes a rod-shaped body with a thread on the outer surface from the end and a nut screwed thereon, the body is expanded from the end opposite to the end face and penetrating the jaw body, a plate, with a through transverse hole on one side containing the rod-shaped body, and a transverse protrusion on the other side with an extra hole containing an additional rod-shaped body including a rectilinear part, end part bent in the direction opposite from the transverse protrusion towards forming an acute or right angle of not more than 90° with the rectilinear part, as well as another end part that has a thread with an extra nut screwed on the outer surface in contact with the plate transverse protrusion. On the bent end part of the additional rod-shaped body, grooves are provided for metal ligature anchoring. On the plate, sharpened protrusions are made facing away from the transverse protrusion and located near the through hole of the plate symmetrically from its axis. The nut screwed on the rod-shaped body from the side facing the plate, has a spherical shape, and the part of the plate through hole facing the nut also has a spherical shape. The plate through hole on the opposite side has an extension to its outer surface. The extra nut from the side facing the plate transverse protrusion and the facing part of the plate transverse protrusion extra hole lateral also have a spherical shape, while the through a hole of the plate transverse protrusion from the opposite side has an extension to the outer surface.;EFFECT: invention provides prevention of bedsores in the jaw mucosal surface under contacting detail parts, simplified installation, improved ease of installation and comfort.;2 cl, 19 dwg
