Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of automatic control lumbar vertebrae longitudinal axis tractor.
Background technology
The illnesss such as protrusion of lumber intervertebral disc, lumbar vertebrae hyperosteogeny, spinal canal stenosis are the common diseases of the elderly, and it is directly affected
To the sciatic nerve of patient, leg and the health of foot, the lighter's waist-leg pain can not be upright, handicapped, and severe one bottom is numb, urine
It is obstructed or even causes to be paralyzed for life.
Current relatively effective method is traction treatment.And traditional traction device is deposited because the bodily form is big, it is necessary to fixed
Place, and ad hoc nursing staff's operation is needed, to patient not only inconvenience but also not in time, directly affect curative effect.
To solve the above problems, occur a variety of portable lumbar vertebrae longitudinal axis tractors in the prior art.Such as：
Utility model (entitled " the portable more work(of utility model of the earlier application of Application No. " CN02208942.X "
Energy lumbar tractor "；The applying date is " 2002.04.11 "), refering to Fig. 1, the Multi-functional portable lumbar tractor includes main body
Frame, main frame are made up of the ＇ of connecting bracket 5 and the ＇ of controllable rack shaft 4, the controllable ＇ of rack shaft 4 ＇ of boosting-rod 6, locking locator
7 ＇ are assemblied on the ＇ of support 5, the ＇ of buffer spring 3 are arranged on the ＇ of rack shaft 4, the spring connection ＇ of force meter 13, main frame lower end is connected with
The ＇ of one arc plate 9, the ＇ of pelvic girdle 10 is fitted with thereon, the ＇ upper ends of main frame 2 are detachably connected the ＇ of a support tube 2, and the support tube 2 ＇ tops are set
There are the ＇ of armpit support 1, the ＇ of 1 ＇ lower support pipe of armpit support 2 to be provided with soft arc and be equipped with the ＇ of band 14, armpit support is provided with the ＇ of shoulder belt 15, pelvic girdle
Upper 10, which are provided through wearing fastening straps 11 ＇, the ＇ of arc plate 9 being fitted in pelvic girdle, passes through the ＇ of self-regulated suspension arrangement 8 with pelvic girdle and connects
Connect, the ＇ of self-regulated suspension arrangement 8 is to be located at the ＇ of arc plate 9 and connected nail and screens through hole on the ＇ of pelvic girdle 10, the ＇ of alignment pin 12.

The motion away from the first guide support 10 is done in the one end connect, while the first drive link 20 and the second drive link 21 is another
Hold to close to the direction of the first drive cylinder 18 and move, in the presence of drive link, the first sliding block 14 and the second sliding block 15 to
The central motion of first slideway 101, crotch's fixing device 13 and shoulder fixing device 12 is finally set to transport in a direction close to each other
It is dynamic, no longer lumbar vertebrae is exerted a force.
Compared to prior art, automatic control lumbar vertebrae longitudinal axis tractor provided by the invention, have the following advantages that
1, the stretching motion of drive cylinder, motion of the sliding block in slideway is converted into the presence of drive link, and then
Drive the remote or close motion of crotch's fixing device 13 and shoulder fixing device 12, not only simple to operate, convenient, Er Qieneng
It is enough to realize accurately bidirectional modulation；
2, there is provided 11 two guide supports of the first guide support 10 and the second guide support, respectively positioned at body
Both sides, using the teaching of the invention it is possible to provide the stable tensile force parallel to backbone direction, overcome the lacking of easily glancing off of exerting a force in the prior art
Point；
3, automatic control lumbar vertebrae longitudinal axis tractor provided by the invention also have it is simple in construction, cost is cheap, and compact, fit
Close patient to use at home, avoid frequently passing in and out hospital, be advantageous to the continuity of patient's treatment, and then improve therapeutic effect.
Refering to 4, in the present embodiment, the first slideway 101 is to be arranged on the sliding cavity inside the first guide support 10, the
Two slideways are to be arranged on the sliding cavity inside the second guide support 11, and open slot is equipped with sliding cavity；
Refering to Fig. 3 and Fig. 5, the first sliding block 14, the second sliding block 15, the 3rd sliding block 16 and Four-slider 17 are by slide plate 141
And it is fixed on two hinged seats 142 at the both ends of slide plate 141 and forms；Slide plate 141 is contained in sliding cavity, the top of hinged seat 142
Leant out from open slot.
Ramp design is the sliding cavity provided with open slot, the slide plate 141 for the accommodating sliding block that can stablize, is not easy sliding block
Derailed from sliding cavity；The hinged seat 142 of sliding block passes through open slot, can be slidably on the basis of drive link is connected.
Refering to 4, in the present embodiment, the center section of the first guide support 10 sets the first solid part 103, and first drives
Cylinder 18 of taking offence is arranged in the first solid part 103, and the first slideway 101 is divided into two sections by the first solid part 103, the He of the first sliding block 14
Second sliding block 15 is separately mounted in two sections of the first slideway 101；
The center section of second guide support 11 sets the second solid part, and it is solid that the second drive cylinder 19 is arranged on second
In portion, the second slideway is divided into two sections by the second solid part, and the 3rd sliding block 16 and Four-slider 17 are separately mounted to the second slideway
In two sections.
First solid part 103 and the second solid part are used for the fixation of two drive cylinders, while also four sliding blocks can be carried out
It is spacing.
Furthermore, it is understood that refering to 4, the both ends of the first slideway 101 and the second slideway be equipped with for control the first sliding block 14,
The positive stop 102 of second sliding block 15, the 3rd sliding block 16 or the stroke of Four-slider 17, positive stop 102 is removably
It is fixed on slideway.
First four sliding blocks are separately mounted in respective chute sections, then positive stop 102 is fixed on corresponding slideway
It is interior, you can sliding block is limited between corresponding positive stop and solid part.
In the present embodiment, ball is provided between slide plate 141 and sliding cavity, the top and bottom of slide plate 141 are equipped with rolling
Pearl storage tank, the ball of 2/3rds volumes are located inside ball storage tank, and the balls of 1/3rd volumes is from ball storage tank
In lean out.
Ball can reduce the frictional force between slide plate 141 and sliding cavity, sliding block is slided in slideway more smooth,
On the one hand, unnecessary abrasion is reduced, on the other hand, the adjustment to lumbar vertebrae tensile force is more smooth.
Certainly, this is only a specific embodiment of the invention, can also be set between slide plate 141 of the invention and sliding cavity
Put other lubrications or reduce the device of resistance.
For example, in another embodiment, more rollers are provided between slide plate 141 and sliding cavity, the bottom of sliding cavity is provided with
The multiple roller storage tanks equidistantly arranged, the roller of 2/3rds volumes are located inside roller storage tank, 1/3rd volumes
Roller leant out from roller storage tank.It is same to realize the purpose for reducing the frictional force between slide plate 141 and sliding cavity.
