Description
Technical field
The present invention relates to the medical apparatus and instruments that a kind of reduction of the fracture is fixed, especially a kind of being used for the treatment of carries out resetting when thoracolumbar vertebral compression fracture resets or the medical equipment of fixation for treatment.
Background technology
Compressed fracture of thoracic vertebra and lumber vertebra is a kind of major injury of common generation, and how it makes spinal column Thoracolumbar disk excessively anteflexion by indirect violence, produces caused by extruding vertebral body.As fallen from eminence pendant, heel or buttocks first land, or bend over work time, weight is fallen by eminence and impacts shoulder, back, all can make Thoracolumbar disk hyperflexion suddenly, causes vertebral body front portion to be compressed into the flexibility fracture of wedge shape.Fracture site is multiple is born in range of activity larger breast waist section, is common with the 12nd thoracic vertebra, the 1st lumbar vertebra.The powerful person of violence, vertebral body can be pressed into fragment, and the adnexa at rear portion avulsion, fracture, dislocation or interlocking can occur at (comprising vertebral plate, pedicle of vertebral arch, articular process, transverse process and spinous process), and severe patient even vertebral body is dislocated and causes spinal cord injury.
In clinical practice, the Restitution ways of thoracolumbar vertebral compression fracture generally has two kinds: 1. bolster method, patient lies supine's hardboard bed, and fracture disposes soft pillow, and bolster is increased gradually, makes spinal column hyperextension.This method coordinates activity of doing exercises, and better effects if, makes anterior longitudinal ligament become anxiety from shrinkage, and the vertebral body front portion and the intervertebral disc that are attached to ligament likely expand, and recover the profile before its compression; 2. couple ankle suspension method patient lies prone, whips with rope after two ankles are lining with cotton pad, is slowly sling by two foots, make health and bed surface angle about at 45 °; Patient suitably can press in affected part with palm, to correct kyphosis deformity.This method is applicable to flexing type stable fracture, and physically fit person.But long term medical practice shows: when bolster method and lumbodorsal muscles exercises, patient is difficult to keep Over-extending position, the reset of fracture to promote compressed vertebral, treat or nurse and improperly also can cause vertebral body recompression, be difficult to the perfect condition at maintenance reduction initial stage.After thoracolumbar vertebral compression fracture, the recovery of compressed vertebral height and maintenance are the difficult points of expectant treatment, are the key factors after determining patient's functional rehabilitation and impact more.
In view of this, the medical treatment device that a kind of novel treatment thoracolumbar vertebral compression fracture is provided is necessary.
Summary of the invention
For the deficiencies in the prior art, the technical problem that the present invention solves is to provide a kind of external fixator recovering and maintain patients with thoracolumbar fracture vertebral height.
For solving the problems of the technologies described above, technical scheme of the present invention is achieved in that a kind of external fixing device for thoracolumbar fracture, the fixing head comprising longitudinal and the support member be connected with described fixing head, wherein, described support member comprises the support portion of elastic arc, the first connecting portion, the second connecting portion and elastic, described first connecting portion is connected to described support portion, and the two ends of described elastic are connected to described support portion and the second connecting portion; Accommodation space is formed between the support portion of described arc and fixing head; Be provided with Height Adjustable actuator in described accommodation space, the inwall that one end of described actuator is connected to described fixing head, the other end is supported in described support portion, and actuator can move along the longitudinally of described fixing head.
Further, described first connecting portion and the second connecting portion are parallel to described fixing head and fix with described fixing head.
Further, described fixing head is provided with chute along longitudinally, described holder is connected to described chute and can along described slide.
Further, be also provided with a plate in described accommodation space, one end of described holder is rotationally connected with described connecting plate, and described connecting plate is fixedly connected on described chute and can along described slide.
Further, described fixing head is provided with some adjustment holes along longitudinally, described holder is connected to described adjustment hole.
Further, be also provided with a plate in described accommodation space, one end of described holder is rotationally connected with described connecting plate, and described connecting plate is fixedly connected on described adjustment hole.
Compared with prior art, the invention has the beneficial effects as follows: adjustable external fixator can recover and maintain vertebral height, after treatment effect, reduce the generation of the sequela such as spinal column is stiff, amyotrophy, breast waist section kyphosis deformity, waist dull pain.
Accompanying drawing explanation
Figure 1 shows that the side view of external fixing device for thoracolumbar fracture preferred forms of the present invention.
Figure 2 shows that the upward view of external fixing device for thoracolumbar fracture preferred forms of the present invention.
Figure 3 shows that the upward view of external fixing device for thoracolumbar fracture second embodiment of the present invention.
Detailed description of the invention
Shown in ginseng Fig. 1 to Fig. 3, be respectively the upward view of the side view of external fixing device for thoracolumbar fracture most preferred embodiment of the present invention, the upward view of most preferred embodiment and the second embodiment.The support member 20 that the fixing head 10 that external fixing device for thoracolumbar fracture of the present invention comprises longitudinal is connected with holder 10 and the actuator 30 be located between fixing head 10 and support member 20.
Fixing head 10 is the plate body being made up rectangle of macromolecular material, it can be have fixing band with holes 11 that its four angles and longitudinal side are provided with, and may correspond on holes 11 in body position is have shoulder fixing belt, chest fixing belt, waist and belly fixing band, buttocks fixing band etc. respectively.
Support member 20 is made up of elastic macromolecular material, and it is placed on fixing head 10, comprises support portion 21, first connecting portion 22, second connecting portion 23 and the elastic 24 of arc.Wherein, first connecting portion 22 is the flat board parallel with fixing head 10 with the second connecting portion 23, elastic 24 and fixing head 10 are in an angle and two ends are connected to the second connecting portion 23 second connecting portion 23 relative to support portion 21, first connecting portion 22 is positioned at the opposite side of support portion 21 and is connected with support portion 21.First connecting portion 22 and the second connecting portion 23 are fixed on fixing head 10 by screw bolt and nut by support member 20 respectively, thus realize the fixing of support member 20 and fixing head 10.
