The technical scheme that solves the problems of the technologies described above is:
The better Fracture of femur traction apparatus of a kind of fixed effect that resets, it is comprised of near-end hold-down screw, connecting rod, traction bow, locking pin, the link of near-end hold-down screw is connected with an end of connecting rod, the rotational structure of regulating length is arranged in the middle of the connecting rod, the other end of connecting rod is connected with traction bow, and traction bow is connected with locking pin.
The better Fracture of femur traction apparatus of the above-mentioned fixed effect that resets, the link of described near-end hold-down screw are rotating shaft connecting structure or universal joint syndeton.
The better Fracture of femur traction apparatus of the above-mentioned fixed effect that resets, the rotational structure of the adjusting length in the middle of the described connecting rod is comprised of sleeve and connecting screw rod, and the screw thread of connecting screw rod and the female thread of sleeve are complementary, and an end of connecting screw rod is spun in the sleeve.
The better Fracture of femur traction apparatus of the above-mentioned fixed effect that resets, the rotational structure of the adjusting length in the middle of the described connecting rod is comprised of sleeve and two connecting screw rods, the thread rotary orientation of two connecting screw rods is opposite, the female thread at sleeve two ends and the screw thread of connecting screw rod are complementary, and two connecting screw rods are spun on respectively the two ends of sleeve.
The better Fracture of femur traction apparatus of the above-mentioned fixed effect that resets, described traction bow and connecting rod are that spiral is screwed into or buckle or latch are connected.
The better Fracture of femur traction apparatus of the above-mentioned fixed effect that resets, described locking pin is Kirschner wire or steinman pin.
Usefulness of the present utility model is:
Near-end hold-down screw of the present utility model is fixed near end of thighbone, locking pin and traction bow are fixed on distal femur, and the middle connecting rod that connects is adjusted near end of thighbone and the middle distance of far-end by the bar that is rotatably connected, make the reduction of the fracture of shortening, and effectively keep and control its length.This resetting means can produce the huge strength that resets by bone connection and lower limb fixation, guarantees resetting smoothly of fracture site, avoids the carrying out that the assistant carries out manual reset impact operation in the art.This utility model is simple in structure, easy to use, has solved the hard problem that resets in the Fracture of femur art, is effective very strong utensil in the clinical operation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of another kind of traction bow of the present utility model.
Labelling is as follows among the figure: near-end hold-down screw 1, connecting rod 2, traction bow 3, locking pin 4, ilium 5, femur 6, connecting screw rod 7, sleeve 8.
