Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, relates to a kind of reduction of the fracture rehabilitation appliances, especially relates to a kind of adjustable chest repositioning fracture of lumbar vertebra rehabilitation 3 d traction device.
Background technology
At present, lumbar vertebra compression fracture expectant treatment method has manual reduction, lower back bolster, lumbar traction etc., and these expectant treatment methods do not consider that vertebral body is a 3-D solid structure, and the active force of single direction can not carry out active homing to vertebral fracture; Mostly be in the market horizontally tracting device, lack lumbar vertebra vertical direction traction equipment.Some apparatus improvement are vertical distraction, but structure is inapplicable, has plenty of traction belt to be directly banded in it patient, in distraction procedure, Hui Dui patient surrounding soft tissue produces compressing, causes patient's sense of discomfort, endurable, is difficult to adhere to, makes therapy rehabilitation be difficult to effectively be carried out; Have plenty of draw force direction and change or reduce, can not effectively draw.Patient is passive participation, and treatment degree is inadequate, the process that does not have patient initiatively to participate in therapeutic process.In the fracture middle and late stage rehabilitation stage, do not consider that lumbodorsal muscles exercises needs an incremental process in addition, lack auxiliary lumbodorsal muscles exercises system, make patient's lumbodorsal muscles exercises not in place.
Summary of the invention
The purpose of this utility model is to provide vertebral body can obtain three-dimensional reset, and patient can initiatively participate in, a kind of adjustable chest repositioning fracture of lumbar vertebra rehabilitation 3 d traction device that therapy rehabilitation successful improves.
This utility model is provided with adjustable tension bow device, band, running block, fixed pulley group and fixture;
Described adjustable tension bow device is provided with six bar mechanism, left screw rod, right screw rod and center adjustment screw rod, six bar mechanism is provided with the 1st～6th rod member, the 1st rod member lower end and left screw rod upper end are spirally connected and fix by left locking nut, the 3rd rod member lower end and right screw rod upper end are spirally connected and fix by right locking nut, the 2nd rod member two ends are hinged with the 1st rod member upper end and the 3rd rod member upper end respectively, the 4th rod member upper end and the 3rd rod member are hinged, the 6th rod member upper end and the 1st rod member are hinged, the 5th rod member two ends are hinged with the 4th rod member lower end and the 6th rod member lower end respectively, center adjustment screw rod through the 2nd rod member and with the 2nd rod member threaded engagement, center adjustment screw rod lower end is connected with the 5th rod movable, band is provided with horizontal band, and laterally band both sides are connected with right screw rod with left screw rod respectively, and running block is installed on described center adjustment screw rod upper end, fixed pulley is assembled on described fixture, and fixture and external stability are provided with stay cord between running block and fixed pulley group, and stay cord top is stiff end, and stay cord tail end is free end.
Described left screw rod and right screw rod bottom are preferably triangular in shape, and the described horizontal band left and right sides is connected with right screw rod bottom with left screw rod respectively.
Described band is preferably also provided with longitudinal drawstring, and longitudinally drawstring is located at horizontal band both sides; Described horizontal band two ends are preferably provided with Velcro or belt fastener, and by Velcro or belt fastener, laterally band can form astragal, is convenient to wrap up human body.
Compared with the prior art, the beneficial effects of the utility model are as follows:
During this utility model application, described fixture can be installed on to bed top, horizontal band is tied to chest or the waist of human body, according to patient's concrete situation, by adjusting the locked position of left locking nut and right locking nut, the effective length of the left screw rod of scalable and right screw rod, the effective length of left screw rod and right screw rod can not equate or not etc., thereby make human body corresponding position be corresponding obliquity, during operation, patient can hold stay cord tail end, stay cord tail end is pulled down, under the combined effect of running block and fixed pulley group, adjustable tension bow device and people know from experience generation lifting force upwards, under human body self-gravity effect, will decompose generation vertical direction, the pull strength of horizontal transverse direction.If longitudinal drawstring in increase, can make longitudinally further to be drawn along human body.By center of rotation adjusting screw(rod), can make the width that described six bar mechanism opens become large or diminish, thereby make band produce transverse traction force.
As can be seen here, the vertebral body that this utility model fully takes into account human body is a 3-D solid structure, by vertical distraction, produces vertical distraction power, and patient's own wt produces a horizontal drag force, by regulating left-and-right spiral bar height to produce horizontal shear force, make vertebral body obtain three-dimensional reset.Be described as follows:
1, adjustable tension force traction bow, conveniently adjusts according to patient's build, guarantees the comfort level of patient in distraction procedure, guarantees the direction of pull strength, guarantees the effect of reduction by traction.
2, after corpus vertebrae replacement, by stationary rope, can maintain traction hight, play the effect with bolster, be conducive to the recovery of height, vertical distraction reduces the compressing to sacrococcygeal region and reduces the risk that decubital ulcer produces simultaneously.
3, it is more laborsaving that movable pulley makes traction, and number can be adjusted according to patient's arm strength, realizes patient from operation, makes patient's upper limbs force be taken exercise simultaneously.
4, taking into full account later stage rehabilitation is an incremental process, can make family members coordinate with patient and carry out back flesh functional exercise; Or adjust pulley number, patient self coordinates by own tractive according to back muscular strength amount size, both tempered back flesh and also tempered upper limbs force simultaneously.
