Изобретение относитс к области медиданской техники и предназначено дл компрессии или даь стракции отломков трубчатых костей.The invention relates to the field of Median technique and is intended to compress or give the fragments of tubular bones.

Известен компрессионно-дастракционный аппарат , содержащий кольца, соединенные между собой ст жными винтами, сшцедер атели, спна1ы и элементы фиксации 1.A compression-dastraction apparatus is known, containing rings interconnected by fastening screws, a stseder teli, spna1y and fixing elements 1.

Однако дл наложени такого устройстеа гре6 )«тс много времени.However, it is a lot of time to impose such a device.

Целью изобретени вл етс сокращение времени наложени аппарата.The aim of the invention is to reduce the overlap time of the apparatus.

Это достигаетс тем, что кольца попарно св заны июжду собой с хомутов, имеют наружные пазы, спицедержатели установлены |«ежду парными кольцами и снабжены сухарем с зубь ми, взаимодействующими с пазами.This is achieved by the fact that the rings are paired in pairs with the clamps, have external grooves, the clip holders are installed between the double rings and are equipped with a biscuit with teeth interacting with the grooves.

Ошцедержатели вьшолнены в виде Btmia cTipoдольным и поперечным отверсти ми на одном из концов, болта с поперечным отверстием под спицу , установленного в поперечное огверстае винта и гаек.The saddle holders are made in the form of a Btmia cTipolate and transverse holes at one of the ends, a bolt with a transverse hole for the knitting needle installed in the transverse screw and nuts.

На фит. 1 изображен компрессионно-дастраквионный аппарат, общий вид; на.г. 2 - спицедержатель; на фиг. 3 - разрез А-А на фиг. 2.On the fit. 1 shows a dastraquion compression apparatus, general view; on 2 - spit holder; in fig. 3 shows section A-A in FIG. 2

Устройство содержит кольца I, соединенные ст жными винтами 2, спицы 3, причем кольца I попарно св заны между собой с помощью хомутов 4 и имеют наружные пазы 5, спицедержатели 6, выполненнью в виде винт 7 с продольным и поперечным отверсти ми а и б. В отверсше б вставл етс болт 8 с поперечным отверстием (на чертеже не показано) под спицу 3, а спицедержатели 6 установлены между парныл« кольцами 1 и снабжены сухарем 9 с зубь ми }0, взаимодейств ующикш с пазами 5. Устройство также имеет гайки И, 12 и 13.The device contains rings I connected by clamping screws 2, spokes 3, and rings I are connected in pairs with each other using clamps 4 and have external grooves 5, spit holders 6 made in the form of a screw 7 with longitudinal and transverse holes a and b. In hole b, a bolt 8 with a transverse hole (not shown) is inserted under the needle 3, and the spokes 6 are installed between the coil rings 1 and equipped with a nut 9 with teeth} 0, which interact with the grooves 5. The device also has nuts And 12 and 13.

Claims

The apparatus is applied as follows. The length of the clamping screws) in 2 is selected in COOT according to the length of the bone fragments. The rings G are rigidly connected to each other by the Vitamn 2. After opening the split rings 1, a limb is placed in Tx, after which the rings are closed with the help of clamps 4 and fixed in the assembled position. Aligners 6 are mounted on rings 1 so that the holes of the screws 7 are directed to the bone fragments. Holding the limb in the center of the rings through the holes of the needle holder, the needle 3 is drilled with a drill through the bristles. After the knitting needles are driven through the bones of the bones, the knitting needles are secured in the agacets with the help of bolts 8 nuts 11. The spokes 3 are tightened by tightening the nuts 12. This is thanks to the matching teeth 10 s; ghar 9 s shades 5 knitting needles 3 it is possible to fusion each other as diametr, w: and on the chord of the rings. Pr loosening the tension in the process of lechosh by shaking nuts 12 can carry out additional heat tension. Eliminate the bone mass of the bone ochlocs. For example, the screw or screw is pressed into the joint, or through the dastrack. and the process of imposing the apparatus is accelerated, and the restoration of working capacity takes place in a shorter time. Claim 1. A compression-distraction apparatus comprising hoofs interconnected with screws, knitting needles, nails and fixing elements, characterized in that, for the purpose of the sacrifice of the apparatus, the rings are pairwise interconnected by means of clamps, they have external grooves, and the tongue holders are mounted between the desks of the rings and are equipped with a cracker, which interact with the grooves.

2.Kympression-distraction apparatus, according to claim 1, characterized in that the spokes are made in the form of a screw with selling and transverse holes at one of the ends, a bolt with cross section under the knitting needle installed in the transverse hole of the screw, and nuts. information, pzhp tye in attention at zspertnze: 1.
