Abstract
The utility model discloses a kind of child femoral shaft fracture 3 d traction device, belong to medical instruments field, recover for child femoral shaft fracture, it includes bottom plate, also include arc frame, sliding bar, wherein described arc frame is fixed by connecting rod and bottom plate, and sliding bar is slidably arranged on arc frame, and pulley is provided with sliding bar.In view of above-mentioned technical proposal, the utility model can realize the cripetura displacement for preventing child femoral shaft fracture, side angulation, front and rear angulation and rotation displacement, while ensure that the security of traction.
Description
Technical field
The utility model belongs to medical instruments field, and specifically, more particularly to a kind of child femoral shaft fracture three-dimensional is led
Leading-in device.
Background technology
In the clinical position of pediatric Orthopaedics, for underage child fracture of femoral shaft it is more at present using be suspended vertically traction or
Person's abduction suspension traction, both traction methods can not correct the front and rear angulation of child femoral shaft fracture well or rotation moves
Position, cause part infant expectant treatment failure and need operative treatment, the body and mind to children causes unnecessary injury, is also family
Treatment is added increased not bear.
The content of the invention
The purpose of this utility model is to provide a kind of child femoral shaft fracture 3 d traction device, and it can realize and prevent
Cripetura displacement, side angulation, front and rear angulation and the rotation displacement of child femoral shaft fracture, while ensure that the security of traction.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：
A kind of child femoral shaft fracture 3 d traction device, including bottom plate, in addition to arc frame, sliding bar, wherein described
Arc frame is fixed by connecting rod and bottom plate, and sliding bar is slidably arranged on arc frame, is provided with and is slided on sliding bar
Wheel.
Further speaking, the sliding bar described in the utility model is realized rotatable and slided by adapter sleeve and sliding bar
Connection.
Further speaking, the pulley described in the utility model is respectively arranged at the both ends of sliding bar by adapter sleeve, and
It is connected in a sliding manner with sliding bar.
Further speaking, the angle between the connecting rod and bottom plate described in the utility model is 30 °.
Further speaking, the arc frame described in the utility model, connecting rod, sliding bar, pulley and adapter sleeve use 304
Stainless steel is made, and bottom plate is wood materials.
Compared with prior art, the beneficial effects of the utility model are：
The utility model by children's hip and the physilogical characteristics of femur, can realize the three-dimensional of child femoral shaft fracture
Traction, avoids cripetura displacement, side angulation, front and rear angulation and the rotation displacement of child femoral shaft fracture, while ensure that traction
Security.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, arc frame；2nd, connecting rod；3rd, bottom plate；4th, sliding bar；5th, pulley；6th, adapter sleeve.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to technical scheme described herein.
Embodiment 1：A kind of child femoral shaft fracture 3 d traction device, including bottom plate 3, in addition to arc frame 1, sliding bar
4, wherein the arc frame 1 is fixed by connecting rod 2 and bottom plate 3, sliding bar 4 is slidably arranged on arc frame 1,
Sliding bar 4 is provided with pulley 5.
Embodiment 2：A kind of child femoral shaft fracture 3 d traction device, wherein the sliding bar 4 is by adapter sleeve 6 and slides
Lever 4 realizes connection that is rotatable and sliding.The pulley 5 is respectively arranged at the both ends of sliding bar 4 by adapter sleeve 6, and with
The mode of slip is connected with sliding bar 4.Angle between the connecting rod 2 and bottom plate 3 is 30 °.The arc frame 1, connecting rod 2, slide
Lever 4, pulley 5 and adapter sleeve 6 are made of 304 stainless steels, and bottom plate 3 is wood materials.The structure of remainder and connection
Relation is identical with the structure described in any previous embodiment and annexation.
In view of above-described embodiment, when in use, its course of work and principle are as follows by the application：
The utility model is fixed on bottom plate 3 using arc frame 1 by connecting rod 2, and sharp between connecting rod 2 and bottom plate 3
Angle is 30 °, and the setting of the angle enables to children's hip abduction maximum to be located within the abduction safety value less than 60 °,
Femoral head poor arterial inflow caused by avoiding hip abduction excessive.
Sliding bar 4 can be slided on arc frame 1 and rotated around adapter sleeve 6, and the purpose so set is so that children
Hip abduction, and cause hip abduction muscle group relaxation, correct femur lateral displacement.And the rotation for passing through sliding bar
The rotation displacement of fracture distal end can be corrected.
By installing the structure of pulley 5 at the both ends of sliding bar 4 in the utility model, and pulley can be on sliding bar 4 certainly
By moving, bend hip angle by the position children of mobile nearside pulley 5 and increase, maximum angle is 130 °.Above-mentioned setting can
So that iliopsoas fully relaxes, angulation before and after children femoral is corrected.
The utility model can correct the cripetura of child femoral shaft fracture, side angulation, front and rear angulation and rotation displacement；Compared with biography
System, which is suspended vertically draw-gear or abducent traction frame, obvious progress.
