SPITSENATYAGIVATEL

摘要

The utility model relates to medicine, namely to traumatology and orthopedics, and can be used in apparatuses extrafocal osteosynthesis comprising administering spokes (ABO), including: in Halo-pelvic ABO extension, during treatment of fractures and bone defects, abnormalities of the pelvis; correction of spinal deformities in children and adults. The utility model is aimed at achieving the ability to provide uniform tension spokes at any angle of their arrangement in the plane of the base support ring ABO (ABO OK) at different orientations OK ABO yaw correctable segment of the patient's body, including perpendicular or parallel to said axis. Said technical result is achieved in that there is provided spitsenatyagivatel comprising a housing having a longitudinal slot; knot retention spokes (UUS) channel and a threaded needle hub; spokes tensioning assembly (ONS), consisting of a threaded shaft and a handle connected to the NCU and cooperating with the housing and mounted on the housing locking assembly spitsenatyagivatelya OK ABO (ABO UVC OK). According to the utility model UFS OK ABO consisting of a support element, configured as a direct part of a hollow cylinder cut off by a plane perpendicular to the plane of said cylinder base; fastening elements to OK ABO (EC OK ABO) placed at the ends of the support member and configured such that their longitudinal axes are oriented relative to the plane of the support member base so that said plane and the base plane OK AVO in the working position ABO were parallel to each other, and fastening to the body element (ECC). At the same time, UFS OK ABO is mounted on a mobile body. NCU further comprises a bore therethrough for the threaded shaft disposed parallel to the channel under the needle, such as a through, and; an inlet opening of the channel under the needle is disposed over the outer surface of the support member in the UVB OK ABO, for example at a distance of 3/4 the diameter of the spokes. NCU is connected to the ONS and the housing for engagement. Most effectively perform the support member in UVC OK ABO as a direct part of a hollow cylinder cut off by a plane perpendicular to the plane of said base of the cylinder, at a distance of 0.3-0.5 of its outer diameter. The maximum efficiency is also provided as a support member in UVC ABO OK mounted on the housing rotatably about the longitudinal axis of the latter in a plane parallel to the horizontal section plane and directed along the length of the body, in a clockwise and counterclockwise 35-40 ° in each of said directions, and UVC OK ABO as a whole is removable. The title compound UVC ABO OK to the housing is achieved in particular when the ECC in UVC ABO OK as a bracket connected to the body, for example via a screw connection, wherein the support member UVC OK ABO installed in the through groove staples. Optimal is when the ends of the support member UVC ABO OK symmetrically arranged EC OK ABO, each of which is in the form of two parallel projections with a clearance therebetween, wherein the longitudinal axis of each of the protrusions may be positioned relative to the base support member UVC plane OK ABO parallel or perpendicular. Using the claimed spitsenatyagivatelya allows you to: improve the efficiency of the treatment of fractures and bone defects in children and adults, in particular, by reducing the frequency of inflammation in the area of ​​the spokes, undeveloped osteomyelitis, lack of secondary displacement of bone fragments; extend the range of application, in particular, due to the possibility of correction of spinal deformities that require Halo-pelvic extension; 5 times to accelerate the spokes tensioning procedure for the installation of ABO. 12 ZP f ly-4-yl., 1 tab., 2 straight.
