Изобретение относитс к медицинской технике, а именно к травматологии , и может быть использовано дл измерени величин деформации кости.The invention relates to medical technology, namely to traumatology, and can be used to measure bone deformation values.
Цель изобретени - одновременное определение величины разрушающей нагрузки и прогиба кости.The purpose of the invention is the simultaneous determination of the magnitude of the breaking load and deflection of the bone.
На фиг.1 изображено устройство общий вид; на фиг.2 - то же, вид сбоку; на фиг.З - шкала нагрузок.Figure 1 shows the device a General view; figure 2 is the same, side view; fig.Z - scale loads.
Устройство состоит из станины 1, на выступе 2 которой с помощью гайки 3 закреплена упруга планка 4 с зенкованными отверсти ми 5. В отверсти х 5 установлены шаровые пальцы 6 захватов 7. Через станину 1 и выступ 2 ввернут резьбовой виит 8 с шарни - ным седловидным упором 9. На винте 8 с другой стороны закреплена ручка- указатель 10, а на станине установлена шкала 11 нагрузок. На станине 1 закреплен микрометр 12, шток 13 которого проходит через отверстие 14 и упираетс в шаровой палец 6.The device consists of a bed 1, on the protrusion 2 of which, by means of a nut 3, an elastic strip 4 with countersunk holes 5 is fixed. In the holes 5 there are ball-shaped fingers 6 of the grips 7. Through the bed 1 and the protrusion 2 screwed threaded viit 8 with articulated saddle-shaped stop 9. On the screw 8, on the other hand, the handle-pointer 10 is fixed, and the scale has 11 scale loads. A micrometer 12 is fixed on the frame 1, the rod 13 of which passes through the hole 14 and abuts against the ball pin 6.
Устройство работает следующим образом .The device works as follows.
Кость укладьгеаетс в захваты 7 и винт В закручиваетс до соприкосновени упора 9 с костью. Микрометр 12The bone is placed in the claws 7 and the screw B is twisted until the stop 9 is in contact with the bone. Micrometer 12

устанавливаетс на О. Затем ввертывают винт 8 и по шкапе I1 определ ют величину нагрузки, а по разнице между перемещени ми шарового пальца 6 и винта 8 определ ют величину прогиба кости при данной нагрузке.the screw 8 is screwed in and the magnitude of the load is determined on the scale I1, and the amount of deflection under this load is determined from the difference between the movements of the ball pin 6 and screw 8.
В момент разрушени кости фиксируют по шкапе 11 нагрузок величину разрушающей нагрузки.At the time of destruction of the bone, the value of the breaking load is recorded on the scale 11 of the load.
