FIELD: medicine. ^ SUBSTANCE: set includes arcs of different type-sizes, Kirchner spokes and bolts of distraction-compression device. Set has bolts with body, which has octahedron form and with screw part 30 mm long. Arc represents 1/3 of ring circumference with openings on both ends, which have form of octahedron. ^ EFFECT: invention ensures reduction of volume-weight parametres, which allows to realise storing and mounting in sterile conditions without preliminary preparation, increase universality of DCA of spoke-containing type by modification of completing parts of DCA, allowing creation of supports in ring, arc versions with regulated internal diametre. ^ 13 dwg |
