Description
Technical field
The present invention relates to a kind of traction apparatus of drawing in the art of in fracture operation, carrying out, belong to the bone surgery set technical field.
Background technology
Fracture of shaft of femur and Methods for Distal Femoral Fractures are clinical common fracture.Operative treatment is its first-selected Therapeutic Method, comprises that intramedullary pin is fixed and blade plate is fixed.Because leg muscle strength such as femur musculus quadriceps are powerful, Fracture of femur takes place because often there is shortened deformity etc. in myotasis in the patient, resets, recovers its length in the art and effectively keep comparatively difficulty.If can not anatomical reduction in the art, complication such as malunion and the lower limb line of force be bad may take place in postoperative.In relevant document, report such as Winquist 520 routine fracture of shaft of femur are through intramedullary nail treatment, and the outward turning deformity of 10 degree takes place to surpass 8% patient.The rotation deformity of 15 degree takes place to surpass in 4 examples (9.5%) among the 42 routine patients of report such as Yang.Braten etc. have measured the top rake of the one-sided fracture of shaft of femur patient's bilateral of 110 routine intramedullary interlocking nail femur, and there is rotation deformity (the bilateral femoral anteversion angle differs and surpasses 15 degree) in 21 examples (19%) patient.Complication such as the bad and malunion of the Fracture of femur postoperative lower limb line of force may cause traumatic arthritis or osteoarthritis.Have a strong impact on patient's limb function and quality of life.
Traction is the important means of Fracture of femur, recovery lower limb length that resets in the art.Need the assistant to help to draw the patient at present in the art, the auxiliary reset fracture is also recovered lower limb length.Yet the reduction of the fracture is often dissatisfied, needs two assistants to control near-end and far-end respectively in the art, can not the stable maintenance reduction of the fracture and lower limb length, may influence therapeutic effect; In addition, two assistants may tie up the patient space, influence patient's operation technique.Therefore design that a kind of to reset, recovers the controllability resetting means that lower limb length also effectively keeps for Fracture of femur be very necessary.
Summary of the invention
Technical problem to be solved by this invention provides the better Fracture of femur traction apparatus of a kind of fixed effect that resets, and this traction apparatus can be implemented tractive in the Fracture of femur position to the patient in art, to recover its length and effectively to regulate and keep.
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 made up 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 made up 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 made up 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 the two ends of sleeve respectively.
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 invention is:
Near-end hold-down screw of the present invention 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 keep and control its length effectively.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 influence operation in the art.The present invention is simple in structure, easy to use, has solved the problem of the difficulty 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 invention;
Fig. 2 is the structural representation of another kind of traction bow of the present invention.
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.
The specific embodiment
The present invention is made up of near-end hold-down screw 1, connecting rod 2, traction bow 3, locking pin 4.
Show among the figure that the link of near-end hold-down screw 1 is connected with an end of connecting rod 2, the rotational structure of regulating length is arranged in the middle of the connecting rod 2, the other end of connecting rod 2 is connected with traction bow 3, and traction bow 3 is connected with locking pin 4.
Show among the figure that the link of near-end hold-down screw 1 is rotating shaft connecting structure or universal joint syndeton, in traction, can avoid producing the rotatory tractive like this and cause the back deformity that resets.
Show among the figure that the rotational structure of the adjusting length in the middle of the connecting rod 2 is made up of sleeve 8 and connecting screw rod 7, can adopt one or two connecting screw rod 7, what show among the figure is two connecting screw rods 7.
When adopting a connecting screw rod 7, the female thread of the screw thread of connecting screw rod 7 and sleeve 8 is complementary, and an end of connecting screw rod 7 is spun in the sleeve 8.When adjusting connecting rod 2 length, be rotationally connected screw rod 7 or sleeve 8 can elongate or shorten the length of connecting rod 2.Because the near-end hold-down screw 1 that is connected with connecting rod 2 one ends adopts the universal joint screw, so the connecting screw rod 7 of connecting rod 2 can rotate.
