APPARATUS OF EXTERNAL BRACING Russian patent published in 2009 - IPC A61B17/64 

FIELD: medicine.

SUBSTANCE: invention concerns medical equipment, namely, traumatology and orthopedy. The apparatus contains blocks-clamps, a screw-coupler, and a basis of longitudinal form with a referring groove. Each block fixative is equal in width to the basis and is executed in the form of a slider with a longitudinal prominence and the clamping plate placed on it which are clamped to the formation of apertures under carving blocking hinges on the interfaced sides of the slider and a clamping plate, and an axis of these apertures axes of blocks-clamps are located perpendicularly. The screw-coupler is located along a longitudinal axis of the basis, and executed with an adjusting aperture on a turn-key basis. Blocks-clamps are clamped to the basis. The basis has section of a double tee with a wall parting the basis on the top and bottom cavities and executed with the referring groove. Each fixative block is supplied by a fixing lath. A prominence of the slider and a corresponding fixing lath of blocks-clamps are located one under the other, consequently, in the top and bottom cavities of a double tee of the basis, on the different sides from its wall, and have sections, reciprocal under the form to sections of corresponding cavities of the double tee. There is not less than four apertures for carving blocking hinges. In a clamping plate, a slider and a fixing lath of blocks-clamps there are coaxial fixing apertures located in front of each other which axes are symmetrised, is perpendicular and with alternating concerning axes of apertures for carving blocking hinges. The screw-coupler is located in two eyes and bound to one of eyes carving bond. The eyes are executed with a fixing aperture and established on clamping plates of the next blocks-clamps and clamped to them a bolt passed through a fixing aperture of an eye, through coaxial to it an aperture executed in the corresponding clamping plate, and fixed on a carving in a corresponding aperture a the slider. The blocks-clamps are clamped to the basis the bolt passed through executed in clamping plate and the slider fixing apertures, spent through referring groove of a wall of a two-Tauri, and fixed on a carving in a corresponding coaxial aperture of a fixing lath. The length of the basis and its height are bound by parity 17.5:1. The length of a referring groove is peer to a difference of length of the basis and the doubled distance from edge of blocks-clamps to the point of an aperture nearest to it under a bolt, executed in a clamping plate.

EFFECT: invention provides expansion of functionality, rising of durability of bracing and reliability of osteosynthesis at treatment of difficult fractures, and also at elongation of long tubular bones, and for replacement of defect of bone after its osteotomy, both at the adult person, and at the child.
