Конструктивно устройство состоит из дуг 1 и 2 с продольными прорез ми 3-6 ступенчатого профил . В пазах прорезей 3-6 размещены болты 7-9 с квадратными головками, на которых креп тс гайки 10 и 11 (другие не показаны), накидные планки 12-19.Structurally, the device consists of arcs 1 and 2 with longitudinal slits of a 3-6 step profile. In the slots of the slots 3-6, there are bolts 7-9 with square heads, on which nuts 10 and 11 are fastened (others are not shown), flanged bars 12-19.

Дуги 1 и 2 соединены резьбовыми стержн ми 20-22 с гайками (не обоз- начены) по обе их стороны.Arcs 1 and 2 are connected by threaded rods 20-22 with nuts (not designated) on both their sides.

Накидные планки 12-19 идентичны и выполнены (на примере планки 12) в виде плоской пластины с продольными пазами 23-24 на концах. В средней части планки 12 расположено продольное окно 25 с изогнутыми бортами 26 и 27 с отверсти ми 28 и 29 под ст жной винт 30 с гайкой 31.Cap strap 12-19 identical and made (for example, strap 12) in the form of a flat plate with longitudinal grooves 23-24 at the ends. A longitudinal window 25 with curved sides 26 and 27 with holes 28 and 29 under the clamping screw 30 with nut 31 is located in the middle part of the bar 12.

В .окне 25 между бортами 26 и 27 установлены идентичные двухплоскост- Ные шарниры 32 и 33. Шарнир, например 32, выполнен из двух полуцилинд- 40 - Р де случаев возможно применение ров 34 и 35, с внутренней стороны упрощенной конструкции этого устройства , дуги которого заменены односторонними полудугами 62 (фиг. 3).In the window 25 between the sides 26 and 27, identical two-plane hinges 32 and 33 are installed. The hinge, for example 32, is made of two half-cylinders - 40 - A case of 34 and 35 can be used from the inside, from the inside of the simplified design of this device, the arc which are replaced by one-sided half-arcs 62 (Fig. 3).

имеющих лунки 36 и 37, стенки которых 38 и 39 выточены под конус.having holes 36 and 37, the walls of which 38 and 39 are turned into a cone.

В лунках 36 и 37 шарнира.32 размещены диски 40 и 41 также с коническими образующими. При сжатии шарнира 32 диски 40 и 41 опираютс кра ми в стенки лунок 36 и 37, не достава их дна 42 и 43. В прилегающих плоскост х дисков 40 и 41 выточены диаметральные канавки 44 и 45, образующие при сложении канал 46, в которьш вставл етс спица 47.In the holes 36 and 37 of the hinge.32 disks 40 and 41 are also placed with conical generators. When the hinge 32 is compressed, the disks 40 and 41 are supported by the edges into the walls of the holes 36 and 37, without having reached the bottom 42 and 43. In the adjacent planes of the disks 40 and 41, the diametrical grooves 44 and 45 are turned, forming with the channel 46 in addition Needle 47.

Спица 47 выполнена в виде тонкого стержн с резьбовым участком 48 и заостренным концом 49 с режущими кромками с одной стороны и четырехгранным хвостовиком 50 под торцовый гаёчньй ключ (не показан). На спицуThe needle 47 is made in the form of a thin rod with a threaded section 48 and a pointed end 49 with cutting edges on one side and a four-sided shank 50 under the allen key (not shown).

Claims

Invention Formula

A device for reposition and fixation of fractures of the metatarsal and pangular foot bones and cysts according to ed. St. No. 1210815, which is based on the fact that, in order to ensure the spatial reposition of the bone fragments, between the longitudinal openings in each cover plate,

47 on both sides of the hinge 32, the locking nuts 51 and 52 are screwed with spherical bases.

The device works as follows.

Arcs 1 and 2 are applied to the foot (or hand) and the clamp is fastened with threaded rods 20-22.

0 The needle 47, tucked into the drill chuck (not shown), through the hinge 32, through soft tissues, is threaded through the bone 53 with access through the lower hinge. 54. Similarly, the needle 55 is conducted through the second fragments of the same bone.

Thus, both fragments of one bone are fixed on the threaded sections of the needles 47 and 55, with the corresponding displacement of which in the hinges 32 and 33 of the strap 12 and the hinges 54 (the other is not visible in the drawing) of the strap 16, the required matching of the bone fragments 53 is achieved.

5 After finishing the reposition of bone fragments 53, - their position is fixed by tightening the nuts 31 on the old screws 30 of the bars 12 and 16, which, in turn, are attached to the arcs 1 and 2 with nuts tO and 11

0 on bolts 7 and 8 (others are not visible). . For greater strength, the needles 47 and 55 are fixed with nuts 51 and 52 (others are not visible).

Fixing bone fragments 53,

g similarly, re-fit and fix the bone fragments 56, 57 and 58 with the spokes 59, 60 and .61.

After consolidation of the fragments, the device is removed in reverse order.

The use of the proposed device allows reducing operational trauma and reducing rehabilitation time.
