摘要：
The present device relates to medical engineering, in particular to the field of surgical instrumentation used when performing osteotomies of long bones by drilling through holes in them.Osteotomy (bone cut) is one of the essential operational techniques in performing a number of orthopedic operations, particularly in limb lengthening. In current clinical practice is widespread osteotomies of long bones, which is carried out by drilling the single or consecutive holes, which are applied along the line of the future osteotomy. This method is used when performing various kinds of osteotomy (transverse, oblique, etc. semicylindrical.) And destinations (correcting for bones and elongations al.).The main structural element of the proposed guide is ferrule which is formed in the housing interior cavity, formed near the through parallel cylindrical (partial profiles) holes which partially overlap each other. Recent designed to accommodate and consistent transposition of conductor when performing an osteotomy osteotomy drill bushings. In the side walls of the housing device there is one through-channel cylindrical section, which are intended for insertion into the bone screws stably fixing guide during the osteotomy. The front part of the cage body passes into a fixed lug adapted to capture and hold the operated bone. A movable guide element, creating together with the fixed lug assembly adjustment of its fixation to the operated bone is a removable tab, which is rearranged in the process of osteotomy in a corresponding hole ferrule and is secured at its housing by a fixing screw. On the internal faces legs and the bottom surface of the housing cage guide applied corrugation (or notches) that improves adhesion device with dissecting bone surface.The apparatus is reliable, simple in construction, versatile and allows by drilling sequentially overlapping apertures perform osteotomy not only in the transverse, but in an oblique plane in a stable fixing guide for dissecting bon
