A kind of bone distraction device
Technical field
The present invention relates to a kind of bone distraction device.
Background technology
For fracture of lower leg or the patient of other lower limb sufferers, owing to lower limb move difficulty, keep a posture for a long time,
It is unfavorable for the rehabilitation of lower limb, and easily causes ankylosis, muscle spasm, even cutaneous necrosis, clinically usually through traction apparatus
Help the rehabilitation of patient's lower limb.The fixing band angle of existing traction apparatus can not adjust, it is impossible to adapts to different patients, and it leads
The dynamics patient drawn can not control voluntarily, often up to less than optimum state, thus can increase the misery of patient.
Summary of the invention
It is an object of the invention to for above-mentioned deficiency, it is provided that a kind of bone distraction device.
Described purpose is achieved by the following scheme: a kind of bone distraction device, including bed body, one end of described bed body
Being provided with riser, the top of described riser is hinged with a slide block by rotating shaft, also includes crossbeam, and the lower surface of described crossbeam is provided with
Chute, also includes No. two slide blocks, and a described slide block and No. two slide blocks are all embedded in chute, and the lateral wall of described riser sets
Having rectangular recess, the one end in described rectangular recess is longitudinally provided with axostylus axostyle, and described shaft rod upper sleeve has central siphon, the edge of described central siphon
Being provided with support arm, the described support arm position corresponding with the termination of crossbeam lower surface is equipped with screwed hole, is provided with in described screwed hole
Screw mandrel, the bottom of described screw mandrel is provided with knop, and the bottom of described No. two slide blocks is provided with pulley, and described pulley is provided with traction
Rope, one end of described pull rope is connected with fixing band, and the other end of described pull rope is connected with hand capstan.
On the medial wall of described riser, the edge with bed body is provided with multiple retainer ring.
The invention have the advantages that the present invention passes through hand capstan and regulates the height of fixing band voluntarily, be conducive to suffering from lower limb
Exercise, adjusted the position of fixing band by the slip of No. two slide blocks according to the length of leg, it is simple to different patients uses,
By rotating shaft, crossbeam is merged with riser, save space.

Detailed description of the invention
Elaborate the preferred embodiment of the present invention below in conjunction with the accompanying drawings.
A kind of bone distraction device, including bed body 1, one end of described bed body 1 is provided with riser 2, and the top of described riser 2 leads to
Cross rotating shaft 3 hinged with a slide block 4, also include that crossbeam 5, the lower surface of described crossbeam 5 are provided with chute 6, also include No. two slide blocks
7, a described slide block 4 and No. two slide blocks 7 are all embedded in chute 6, and the lateral wall of described riser 2 is provided with rectangular recess 8, institute
Stating the one end in rectangular recess 8 and be longitudinally provided with axostylus axostyle 9, described axostylus axostyle 9 is cased with central siphon 10, the edge of described central siphon 10 is provided with props up
Arm 11, described support arm 11 position corresponding with the termination of crossbeam 5 lower surface is equipped with screwed hole 12, sets in described screwed hole 12
Having screw mandrel 13, the bottom of described screw mandrel 13 to be provided with knop 14, the bottom of described No. two slide blocks 7 is provided with pulley 15, described cunning
Wheel 15 is provided with pull rope 16, and one end of described pull rope 16 is connected with fixing band 17, the other end of described pull rope 16 and hands
Ceeling dish 18 is connected.On the medial wall of described riser 2, the edge with bed body 1 is provided with multiple retainer ring 19.
The two ends of axostylus axostyle 9 are fixing with rectangular recess 8 to be connected, and central siphon 10 is rotating to be enclosed within axostylus axostyle 9, one end of support arm 11
Fixing with central siphon 10 and be connected, hand capstan 18 is fixedly installed on the edge of bed body 1, and pull rope 16 is arranged in retainer ring 19.
During use, rotated on axostylus axostyle 9 by central siphon 10, support arm 11 is removed in rectangular recess 8, screw mandrel 13 is screwed in
In screwed hole 12, making crossbeam 5 fix with support arm 11, now crossbeam 5 is for being horizontally disposed with, and patient lies in bed body 1, according to patient's lower limb
The length in portion, by the slip in chute 6 of No. two slide blocks 7, regulates the position of fixing band 17, is arranged on fixing band by suffering from lower limb
In 17, shaking with hands hand capstan 18, fixing band 17 is upwards sling by pull rope 16.
With rear, back out screw mandrel 13, support arm 11 is merged in rectangular recess 8, slided on slide block 4 by chute 6, make horizontal stroke
Beam 5 moves, and after No. two slide blocks 7 and slide block 4 laminating, is made the lateral wall laminating of crossbeam 5 and riser 2 by rotating shaft 3.
Present embodiment does not simply limit its protection domain to the exemplary illustrated of this patent, and those skilled in the art are also
It can be carried out local to change, as long as no the spirit beyond this patent, all be considered as the equivalent to this patent, all
Protection domain at this patent.
