A kind of bone distraction device
Technical field
The present invention relates to a kind of bone distraction devices.
Background technology
For the patient of fracture of lower leg or other lower limb sufferers, since lower limb move difficulty, maintain a posture for a long time,
It is unfavorable for the rehabilitation of lower limb, and easily causes anchylosis, muscle cramp or even cutaneous necrosis, clinically often passes through draft gear
To help the rehabilitation of patient's lower limb.The fixed band angle of existing draft gear cannot adjust, and can not adapt to different patients, lead
The dynamics patient drawn cannot voluntarily control, often up to less than optimum state, so as to increase the pain of patient.
The content of the invention
The purpose of the present invention is being directed to above-mentioned deficiency, a kind of bone distraction device is provided.
The purpose is achieved by the following scheme:A kind of bone distraction device, including bed body, one end of the bed body
Equipped with riser, the top of the riser is hinged by shaft and No.1 sliding block, further includes crossbeam, and the lower surface of the crossbeam is equipped with
Sliding slot, further includes No. two sliding blocks, and the No.1 sliding block and No. two sliding blocks are embedded in sliding slot, are set on the lateral wall of the riser
There is a rectangular recess, one end in the rectangular recess is longitudinally equipped with axostylus axostyle, and the shaft rod upper sleeve has central siphon, the edge of the central siphon
Equipped with support arm, the support arm and the corresponding position in end of crossbeam lower surface are equipped with threaded hole, are equipped in the threaded hole
Screw, the bottom of the screw are equipped with knop, and the bottom of No. two sliding blocks is equipped with pulley, and the pulley is equipped with traction
Rope, one end of the traction rope are connected with fixed band connection, the other end of the traction rope with hand capstan.
On the madial wall of the riser and the edge of bed body is equipped with multiple retainer rings.
The present invention has the following advantages:The present invention voluntarily adjusts the height of fixed band by hand capstan, is conducive to suffer from leg
Practice, the position of fixed band is adjusted by the slip of No. two sliding blocks according to the length of leg, is used convenient for different patients,
Crossbeam with riser is merged by shaft, saves space.

Specific embodiment
The preferred embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.
A kind of bone distraction device, including bed body 1, one end of the bed body 1 is equipped with riser 2, and the top of the riser 2 leads to
It is hinged with No.1 sliding block 4 to cross shaft 3, further includes crossbeam 5, the lower surface of the crossbeam 5 is equipped with sliding slot 6, further includes No. two sliding blocks
7, the No.1 sliding block 4 and No. two sliding blocks 7 are embedded in sliding slot 6, and the lateral wall of the riser 2 is equipped with rectangular recess 8, institute
It states one end in rectangular recess 8 and is longitudinally equipped with axostylus axostyle 9, central siphon 10 is cased on the axostylus axostyle 9, the edge of the central siphon 10 is equipped with branch
Arm 11, the support arm 11 and the corresponding position in end of 5 lower surface of crossbeam are equipped with threaded hole 12, are set in the threaded hole 12
There is screw 13, the bottom of the screw 13 is equipped with knop 14, and the bottom of No. two sliding blocks 7 is equipped with pulley 15, the cunning
Wheel 15 is equipped with traction rope 16, and one end of the traction rope 16 is connected with fixed band 17, the other end and hand of the traction rope 16
Ceeling disk 18 is connected.On the madial wall of the riser 2 and the edge of bed body 1 is equipped with multiple retainer rings 19.
The both ends of axostylus axostyle 9 are fixedly connected with rectangular recess 8, and central siphon 10 is rotatably sleeved on axostylus axostyle 9, one end of support arm 11
It is fixedly connected with central siphon 10, hand capstan 18 is fixed at the edge of bed body 1, and traction rope 16 is arranged in retainer ring 19.
In use, being rotated by central siphon 10 on axostylus axostyle 9, support arm 11 in rectangular recess 8 is removed, screw 13 is screwed in
In threaded hole 12, crossbeam 5 is made to be fixed with support arm 11, crossbeam 5 is horizontally disposed at this time, and patient is lain in bed body 1, according to patient's leg
The length in portion by slip of No. two sliding blocks 7 in sliding slot 6, regulates the position of fixed band 17, will suffer from leg and be arranged on fixed band
In 17, hand capstan 18 is shaken with hands, traction rope 16 slings fixed band 17 upwards.
With rear, screw 13 is backed out, support arm 11 is merged into rectangular recess 8, is slided by sliding slot 6 on sliding block 4, makes horizontal stroke
Beam 5 moves, and after No. two sliding blocks 7 are bonded with No.1 sliding block 4, is bonded crossbeam 5 and the lateral wall of riser 2 by 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
Local change can be carried out to it, as long as it does not exceed the essence of this patent, all be considered as the equivalent substitution to this patent, all
In the protection domain of this patent.
