Abstract

The invention relates to a system capable of enabling difference realignment to be carried out on a spinal column under tensile force, in particular to tension equipment. The tension equipment comprises a patient locating device, a tension force generation driver, a locating device, a patient interface device and a control system. The control system has feedback to synthesized tension force vector applied to the spinal column of a patient. When a treatment tension level is exerted on the spinal column of the patient, one of the position of the tension force generation driver and the position of the patient is allowed to be adjusted or both the position of the tension force generation driver and the position of the patient are allowed to be adjusted. The tension device automatically adjusts the angle of the combined tension force vector, and therefore during adjustment of the position of the tension force generation driver and the position of the patient, the magnitude of the vector is enabled to be kept ideal and constant, and the fact that due to the fact that the magnitude of the combined tension force vector is changed, the risk that muscle beside the spinal vertebra contracts is induced is reduced, and buckling of a spinal column section is promoted.

Description

Under pulling force, spinal column is carried out the system that diversity is aimed at again

Technical field

The present invention relates to a kind of system of spinal column so that spinal disease is treated that pulling force is applied to the patient.The invention particularly relates to a kind of system, this system makes the treatment angular oscillation and does not change the expection pulling force under pulling force in therapeutic process, specific spinal column is carried out diversity again aim at (DRV), its objective is and further loosen the spinal column paravertebral muscles, increase intervertebral disc Hui Na, and stimulate articular cartilage (for example, the facet joint cartilage), as the means of a kind of promotion continuous passive motion (CPM) benefit.

Background technology

The Physical Therapist utilizes spinal column pressure reduction to treat various spinal diseases, comprises intervertebral disk hernia, degenerative disc disease, sciatica, rear facet joint syndrome and postoperative pain.Decompression treatment stems from traditional treatment based on traction, and traction therapeutic is placed in state of tension by external force (for example Physical Therapist with hands or pass through automated procedure) with spinal column.Typically, during traditional treatment based on traction, spinal column is in continuous state of tension.The difference of decompression treatment and traditional traction therapeutic is, pulling force is applied to spinal column with specific angle.And, during decompression treatment, use various pulling force or recycle various pulling force in whole treatment cycle, thereby making the spinal column paravertebral muscles loosen and fatigue, allow disc separation.These functions provide seamlessly transitting between the different stage of pulling force.In tradition traction or decompression treatment, the spinal column pulling force all kept 30 minutes or the longer cycle.

Because spinal column is placed in state of tension, thus the spinal vertebrae separation, in order to allow intervertebral disc again to be aligned in its appropriate location.This effect makes intervertebral disk hernia to cure in non-load condition if having time.In addition, polytrophic spinal fluid (vertebral pulp) is directed to the position of pulling force by the negative pressure that is produced by the separation of vertebra.The spinal column paravertebral muscles by with external force resist mutually strain and participate in unconsciously spinal column " stretching " reaction.And sentient people (patient) may be unconsciously and/or is subconsciously shunk spinal column muscle, as the opposing reaction to pulling force.One of them of above-mentioned patient reaction or both all reduced the effectiveness of spinal column dragging or spinal column pressure reduction treatment.

An example of common spinal column pressure reduction therapy system has utilized the non-feedback that is connected to the patient via patient interface device (for example pull strap and/or patient-securing strap) to provide pulling force to produce driver (any type that motorized motions, pneumatic actuation, magnetically-actuated, hydraulic-driven or chemical energy drive).The patient lies on the back on the therapeutic bed body, and head is positioned at the far-end that produces the pulling force source.The upper body holder of patient is fastened to patient's upper body the distal portion (this end of bed from the source that produces pulling force farthest) of bed.Lower body holder carries out fastening around waist, and with the point that connects pull strap.Pulling force produces driver output and increases or reduce to change with the attached synthetic pulling force of some generation to the patient.Utilize Linear actuator (any type of motorized motions, pneumatic actuation, magnetically-actuated, hydraulic-driven or chemical driver) thus raise and reduce the point (treatment localizer) that pull strap pulls with respect to attached position to the patient, thereby the angle of regulating the pulling force of using.System also comprises tension measuring device (for example, force cell), and it is connected with patient's conllinear with pulling force generation driver, produces actuator control device (for example computer) thereby pulling force information is conveyed to pulling force.System operates as the controlled feedback loop, thereby the pull-up curve of expection can be applied to the patient, and can verify the power of practical application by computer.

But in above-mentioned example, fix in the process of pulling force effect with respect to the point that the pull strap of attached position to the patient pulls.Because the direction that pulls is the spinal column that the spinal column that both had been not parallel to the patient also is not orthogonal to the patient, and because patient's (in this example) its head of lying on the back is positioned at the far-end in the pulling force source of application, so the pulling force of using can be modeled as two force vectors, force vector and patient's spinal column conllinear and away from head, another force vector is perpendicular to patient's spinal column.In the situation that the patient is prostrate, it is identical that the direction of the horizontal component that the pulling force of application is made a concerted effort will keep, yet the direction of the vertical component that the pulling force of using is made a concerted effort will be put upside down.

One of spinal column pressure reduction definition property characteristic is, pulling force is used at a certain angle, and special angle (described angle is specific for the design of each device) affects specific intervertebral disc position.The angle of the pulling force of using by adjusting and make specialist can treat ad-hoc location damage, for example spinal column intervertebral disk hernia to the ability that the position of spinal column elongation in spinal column positions.In fact, the position of spinal column elongation positioned the treatment benefit maximization that makes each treat the rank sections.Traction (wherein advocate and will use with the spinal column conllinear) does not attempt to make the spinal column elongation maximization of specific intervertebral disc position.

The different intervertebral spaces of the different angles relative effect that pulling force applies, the existing equipment of describing hereinbefore provides general guidance reference.These angles can be calculated by a lot of modes; Calculating for these angles does not have the universal standard.Pulling force vector by will use (spinal column pressure reduction equipment manufacturers institute specifically) and corresponding iconography data relation analysis, which (which) intervertebral space of spinal column pressure reduction device manufacturer computes is affected.Shown to these iconography data characteristicses " average spinal column " (based on the research of the measurement that a lot of patients are carried out) or " desirable spinal column " (based on best-fit mathematics modeling of spinal column).

At present, before the spinal column pressure reduction treatment, routine need to be carried out NMR (Nuclear Magnetic Resonance)-imaging (MRI), thereby identifies affected intervertebral disc degree.After determining intervertebral space situation that MRI shows, specialist is followed the pulling force treatment angle that the suggestion setting of spinal column pressure reduction equipment manufacturers applies.

Specialist can be by judging for " most probable " of particular patient appropriate treatment angle to the treatment angle of patient's physical examination, advanced imaging patients (MRI, CT, X ray etc.), spinal column pressure reduction device manufacturer design with the experience of spinal column pressure reduction device.When the patient is on the spinal column pressure reduction device, fasten the decompression band, specialist will be determined at last for the treatment angle.Specialist is observed the patient body position, palpation patient's spinal column and/or other related physical, and/or inquiry patient, thus finally determine the correct treatment angle of this particular patient.

Once you begin treat and be provided with the patient treatment angle, produce specific spinal column pressure reduction pull-up curve.Specific spinal column pressure reduction pull-up curve is made of some maximum pull ranks and lowest pull rank, at the persistent period internal recycle for the treatment of.Circulation between strong pulling force rank and weak pulling force rank makes the disorder of spinal column paravertebral muscles and loosens, and promotes intervertebral disc Hui Na, and produces the negative pressure region that can suck fluid in spinal column.

Yet present traction or decompression schedule, even the location Calculation result by integrated system, patient body position and from patient's feedack, can finally determine the correct treatment angle of this particular patient, thereby with a relatively accurate angle, decompression power is put on lesion locations, but this angle initialization is fixed.When concrete treatment, still probably with minor deviations, and if there is this little deviation can not get proofreading and correct, will cause the patient can't obtain best therapeutic effect.Because application of force angle is fixed, the fluctuation that can not carry out various curves in a trickle scope changes in addition, can't realize vertebral body facet joint continuous passive motion (CPM) in decompression.Clinical proof, continuous passive motion only do not have obvious rehabilitation efficacy in extremities joint physiotherapy and rehabilitation field, and be same, and same positive treatment meaning is also arranged in the spinal column pressure reduction therapeutic process.When decompression power puts on pathological changes vertebral body zone, if in the situation that do not change the zone of action of power, pulling force is carried out the trickle angular adjustment (0.5 °～+ 0.5 °) of a full curve, will produce the reciprocating motion of one-period, impel effective decompression to carry out altofrequency to intervertebral disc and periodically proofread and correct, and then form a kind of useful continuous passive motion (CPM).this motor process, can not only promote the blood circulation of lesions position, improve the nutrition exchange velocity, more can provide for the reparation of intervertebral disc cartilage endplate a desirable interior environment, simultaneously, decompression angle fine setting for the curve that carries out is proofreaied and correct, its angular adjustment is a kind of level and smooth curvilinear rows transition, to can not conduct potential change by inducing neural, namely can not produce muscle of back group proprioreceptor stimulates, muscle of back still will be received treatment under fully lax state, like this, the effective maximum decompression power that system provides can better act on intervertebral disc, simultaneously, this continuous passive motion (CPM) is of value to the Hui Na of intervertebral disc, and then promotes the bleeding back of moisture, nutrient substance of pathological interspinal dish, promotes to become the intervertebral disc hydration.

Summary of the invention

The present invention is intended to illustrate a kind of unique method for improvement of prior art, makes the spinal column paravertebral muscles loosen and intervertebral disc hydration again, and does not increase the time that spends in treatment.The present invention is intended to illustrate a kind of unique method that promotes the continuous passive motion (CPM) of facet joint rehabilitation for gain.The present invention proposes a kind of system, in the therapeutic process under being in state of tension, particular vertebra is carried out diversity and again aims at, and do not change the expection pulling force size.The system that proposes can illustrative system mechanical kinetics and mechanical advantage, and be calibrated predict the increase of synthetic pulling force and reduce, the increase of synthetic pulling force can occur and reduce otherwise change the treatment angle under the pulling force active state.The system that proposes can increase and reduce the treatment angle under state of tension and not change the size of expection pulling force vector, cause that particular vertebra is more and less aims at, receiving by returning of intervertebral disc in the endplate junction increases the hydration that promotes those intervertebral disc and increases, and the spinal column paravertebral muscles is loosened and disorderly increasing.As preferably, the diversity of vertebra is aimed at the treatment angular range that can extend again greater than the scope around specific spinal segments angle.

Usually, the patient lies on the back on therapeutic bed, and its lower spinal column is above Lordosis support.Lordosis support is used for lordotic summit is positioned, as calculate the common metric for the treatment of angle in average or desirable patient's spinal column form.Except being the setting for the treatment angle of specific spinal column pressure reduction or traction apparatus, this device also comprises specifies the treatment angle that affects the ad-hoc location intervertebral disc.Although spinal column pressure reduction or traction apparatus comprise that it not is essential that designer's treatment angle is specified, and is prevalent in prior art.

Average or ideal ray photograph spine model generally includes average sections angle and single order or the measurement of second order standard deviation at least.In lumbar vertebra, the sections angle refers to the lordotic angle between one or more vertebras.The sections angle that example of the present invention is used is between fifth lumbar vertebra and first sacral vertebra or L5-S1, the 4th and fifth lumbar vertebra or L4-L5 between, between the third and fourth lumbar vertebra or L3-L4, second and third lumbar vertebra or L2-L3 between and the angle between the first and second lumbar vertebras or L1-L2.

The treatment angle that the design of spinal column pressure reduction equipment provides can and extend its intervertebral space with vertebral alignment, thereby reaches average or desirable spinal column.As indicated above, the difference of the lordosis degree between vertebral levels can fluctuation a little above or below average or ideal model.By utilizing diagnostic scan and spinal column pressure reduction equipment treatment angle design, specialist can make specific pathological changes spinal alignment in decompression.

In one embodiment of the invention, if spinal column pressure reduction equipment is designed to allow the treatment Angulation changes and does not change the expection pulling force, this equipment can make the treatment angle replace rhythmically in therapeutic process in a plurality of cycles so.No matter only for the tailor-made cycle that is used for maximum pull, or only for the tailor-made cycle that is used for lowest pull, or during whole treatment, perhaps during some other subsets for the treatment of stage, this equipment can both be smoothly and is made rhythmically the treatment angle alternately, thereby further loosen and disorderly spinal column paravertebral muscles, and increase intervertebral disc Hui Na.In order to increase safety, treat the increase of angle and reduce to be limited in less treatment angular range, for example 0.5 degree.For a certain intervertebral space is reduced pressure, from L5-S1, all its underpart intervertebral spaces all must be aimed at and reduce pressure.Yet for example, this device can be set to reduce default treatment angle with the amplitude of 0.5 degree, then increases to be back to the treatment angle that specialist arranges, thereby makes the top intervertebral space unaffected.If the treatment differential seat angle opposite sex is enough little and the patient correctly aims on the spinal column pressure reduction device, this device can only be aimed at the particular vertebral disc gap of pathological changes discriminatively again so, neither affects the top intervertebral disc space and does not also affect the bottom intervertebral disc space.For example, if specialist correctly is aligned in the patient on the spinal column pressure reduction device, and the treatment angle is set to affect the L3-L4 intervertebral disc space, this angle is inevitable so also makes L5-S1 and L4-L5 vertebral alignment, thereby from first to last pulls all three intervertebral disc space and make all three intervertebral disc space aim at.And making the L4 vertebra again aim at respect to L3 vertebra diversity ground by enough little treatment angle, this will only affect this intervertebral disc space, makes the spinal column paravertebral muscles of this position maximize to loosen, and promotes the intervertebral disc Hui Na that this is regional.

Fascitis is the generally source of backache, and may be reduced by the amount of the articular cartilage on facet joint to cause.For knee and ancon, continuous passive motion (CPM) relates to the growth of articular cartilage for stimulation and the generation of the rehabilitation factor is well-known.And CPM promotes the rehabilitation in other joint also to carry out abundant research, at affected intervertebral disc space place, vertebra is carried out diversity and again aims at for facet joint and also serve as the CPM treatment.By vertebra being carried out the aligning again of diversity, the benefit of CPM can be treated the larger zone that angular range extends to spinal column by increase.

In another embodiment of the present invention, specialist can be regulated the treatment angle under state of tension, locates each intervertebral disc space, and can be for the treatment computer of this patient with those angle input spinal column pressure reduction equipment.Then, for example, this equipment can begin to apply pulling force at L5-S1 gap place, and the diversity that starts those vertebras is again aimed at and is continued one group of time cycle, also make the L4-L5 gap aim at thereby then increase overall situation treatment angle, and the diversity that again starts the L4-L5 vertebra is again aimed at and is continued one group of time cycle.This equipment can extend to the L1-L2 gap in this way always, the CPM benefit is extended to all facet joints of bottom spinal column.

In another embodiment of the present invention, the diversity of vertebra is aimed at any zone that can be applied to spinal column again.

Fig. 4 A and 4B are respectively two views of lower spinal column (400 and 401).Fig. 4 A shows to treat angle 490 and applies synthetic pulling force vector F 402 spinal column before.Fig. 4 B shows and applies described synthetic pulling force vector F 402 spinal column afterwards.

HPT tangent line 420,430,440,450,460 and 470 is plotted in the trailing edge of vertebral body S1 410, L5 411, L4 412, L3 413, L2 414 and L1 415.

Synthetic pulling force vector F 402 connects lower body holder 118 by patient interface device 120 and is applied to patient 110.Lower patient-securing strap 118 is designed to produce synthetic pulling force vector F 402 at the base portion place of rumpbone 410, be in this embodiment of the present invention supine patient 110 below.When being decomposed into vertical component Fy 404 and horizontal component Fx 403, synthetic pulling force vector F 402 acts on lower spinal column 400/401 in two ways.At first, vertical component Fy 404 can be considered 310 tops, top, center that are promoted to lordosis support member 112 from rumpbone 410, is subject to simultaneously the opposing of lordosis summit the 3rd vertebra L3 413 of spinal column.Horizontal component Fx 403 can be regarded as pulling all aligning spinal segments, so that the spinal column elongation.

Because there is no External Force Acting on spinal column, and supposition nature lordosis more or less can be present between all sections of spinal column under the patient, so in Fig. 4 A, spinal segments 410,411,412,413,414, the 415 and 416 non-vanishing values of sections angle (aligning).If a bit all there is no the nature lordosis in lower spinal column 400, and simultaneously not from then not protruding, so except zero degree just without any need for the treatment angle.

In Fig. 4 B, 402 act on the spinal column of bottom with joint efforts.Drive lower body holder 118 by patient interface device 120,402 act on vertebral levels S1 410 with joint efforts.As general guilding principle, the size of synthetic pulling force 402 is set to 1/2nd of weight in patients, and this is the convention of this area; Yet specialist is had a responsibility for adjusting its size and is made it be enough to promote the lower part of the body and patient's lower part of the body, rumpbone/pelvis/buttocks are rotated to correct position.Make vertebral levels S1 410 promote and rotation with respect to subordinate's soleplate of L5 411 according to the vertical component Fy 404 of synthetic pulling force 402.The angle that applies 490 of synthetic pulling force 402 is θ ₁-θ ₀, 430-420, it is enough to make the rear side of vertebral body S1 410 and L5 411 parallel to each other, thereby " aligning ".In case vertebral body S1 410 and L5 411 aim at, intervertebral disc leading edge and trailing edge all are depressurized 480.Along with synthetic pulling force 402 circulates between minimum and maximum level, vertebral body S1 410 and L5 411 also aim at or misalignment thereupon.

The aligning of vertebral body S1 410 and L5 411 and misalignment cause the disorder of spinal column paravertebral muscles and loosen, particularly when synthetic pulling force 402 circulates smoothly.In addition be vertebral body Mechanical Moving relative to each other because the process of Hui Na occurs, as the aligning of described vertebral body and misalignment described, the aligning of vertebral body S1 410 and L5 411 and misalignment cause receiving increase returning of the soleplate place of vertebral body intervertebral disc.In addition, the vertebral body S1 410 that has aimed at and the elongation 480 of L5 411 cause the decline of the dmm of extended position, and then cause that vertebral pulp moves in spinal column.

Fig. 5 A and 5B are respectively two views of lower spinal column (500 and 501).Fig. 5 A shows to treat angle 591 and applies synthetic pulling force vector F 502 spinal column before.Fig. 5 category-A is similar to Fig. 4 B, has rotated angle 490 and has extended distance 480.Fig. 5 B shows and applies described synthetic tensile force f 502 spinal column afterwards.

HPT tangent line 530,540,550,560 and 570 is plotted as the back at vertebral body L5 511, L4 512, L3 513, L2 514 and L1 515.

F 502 drives lower body holders 118 by patient interface device 120 and is applied to patient 110 with joint efforts.Lower patient-securing strap 118 is designed to produce synthetic pulling force vector F 502 at the base portion place of rumpbone 510, be in this embodiment of the present invention supine patient 110 below.When being decomposed into vertical component Fy 504 and horizontal component Fx 503, synthetic pulling force vector F 502 acts on lower spinal column 500/501 in two ways.At first, vertical component Fy 504 can be regarded as being promoted to from rumpbone 510 310 tops, top, center of lordosis support member 112, is subject to simultaneously the opposing of lordosis summit the 3rd vertebra L3513 of spinal column.Horizontal component Fx 503 can be regarded as pulling all aligning spinal segments, so that the spinal column elongation.

In Fig. 5 A, only there are S1 510 and L5 511 to aim at, as described in Fig. 4 B.Other spinal segments 511,512,513,514,515 and 516 does not have zero sections angle (aligning), 402 is to act on epispinal only enough to aim at 510 and 511 treatment angle because make a concerted effort.In addition, suppose that the nature lordosis more or less can be present between all sections of spinal column under the patient.If a bit all there is no the nature lordosis in lower spinal column 500, and simultaneously not from then not protruding, so except zero degree just without any need for the treatment angle.

In Fig. 5 B, 502 act on lower spinal column with joint efforts.By the mode of initial 402 S1 510 that make a concerted effort, drive lower body holder 118 by patient interface device 120,502 act on vertebral levels L5 511 with joint efforts.As general guilding principle, the size of synthetic pulling force 502 is set to 1/2nd of weight in patients, and this is the convention of this area; Yet specialist is had a responsibility for adjusting its size and is made it be enough to promote the lower part of the body and patient's lower part of the body, rumpbone/pelvis/buttocks are rotated to correct position.By the mode of 402 S1 510, make vertebral levels L5 511 promote and rotation with respect to subordinate's soleplate of L4 512 according to the vertical component Fy504 that synthesizes pulling force 502.The angle that applies 591 of synthetic pulling force 502 is θ ₂-θ ₁, 540-530 adds 590 angle, and it is enough to make the rear side of vertebral body L5 511 and L4 512 parallel to each other, thereby " aligning ".In case vertebral body L5 511 and L4 512 aim at by the mode of 402 S1 510 and L5 511, intervertebral disc leading edge and trailing edge all are depressurized 581 and 580.Along with synthetic pulling force 502 circulates between minimum and maximum level, vertebral body L5 511 and L4 512 and S1 510 and L5 511 also aim at or misalignment thereupon.

In this embodiment of the present invention, the diversity of vertebra is aimed at again, and (DRV) is achieved.It can be set to negative variance, and it makes the treatment angle increase to and make the pathological changes spinal alignment, thereby and reduces an angle and do not affect the top intervertebral disc space.Also can be set to positive variance, it affects higher level's intervertebral space thereby described treatment angle makes the pathological changes spinal alignment and make angle increase, and makes angle reduce to get back to initial setting up from the treatment angle.Can be set to just-negative variance, it is above and make angle be decreased to below initial setting up that it will make angle increase to initial setting up.Can be set to be in any angle in the scope of these patterns.Can be arranged so that vertebra aims at again with constant ratio or modulation rate diversity ground.Can be set to increase gradually and reduce the DRV angle modulation.In the embodiment of Fig. 6, opened DRV, it is set to the initial therapy angle of 12 ° 641, and it is set to negative variance, and it smoothly is decreased to 11 ° 643 and again returns back to the initial therapy angle in the scope of 1 °.It is arranged so that the treatment angle changes 651 with sinusoidal manner.

The spinal column 600 of Fig. 6 A is in the maximum therapy angle 641/338 that is arranged by specialist, so that S1 610 and L5 611 aim at, and makes intervertebral disc space extend 680 according to this aligning.In Fig. 6 A, spinal column is in the summit 661 of the treatment angle curve 651 that changes with sinusoidal manner that forms according to embodiments of the invention.At each 661 place, summit along treatment angle curve 651, spinal column will be in by in 600 alignments of indicating.

The spinal column 601 of Fig. 6 B is in minimum treatment angle 643/608, reduces the aligning of S1 610 and L5611.In Fig. 6 B, spinal column is in the trough 662 of the treatment angle curve 651 that changes with sinusoidal manner that forms according to embodiments of the invention.Initial therapy angle 338 reduces (θ with sinusoidal manner _DRV) 609 to (θ _Temp) 608.In this embodiment of the present invention, the initial therapy angle 641 of 12 ° reduces 1 ° and arrives 11 ° 643.At each trough 662 places along treatment angle curve 651, spinal column will be in alignments by 601 indications.

The spinal column 603 of Fig. 6 C is similar to spinal column 601, and vertebra S1 610 and L5 611 have aimed at 663 again to initial therapy angle 338.

Fig. 7 A-7D represents to treat screen 700, and it may be displayed on the spinal column pressure reduction device of system 10 and/or prints.In screen 700, shown vertically aligned four figure, Fig. 7 A, Fig. 7 B, Fig. 7 C and 7D are to draw for identical horizontal scale (time).

In Fig. 7 A, shown the pull-up curve of expection.In this embodiment of the present invention, the expection pull-up curve is a series of minimum and maximum pulling force ranks, is increased by the logarithm in pulling force 711 to connect with being connected.The y axle 710 of Fig. 7 A is pulling force, draws take pound as unit, is shown as from zero to 160 pounds.According to Fig. 7 A, the maximum pull rank is 140 pounds, and the lowest pull rank is 30 pounds.

In Fig. 7 B, the treatment angle was drawn according to the time.Y axis 720 is treatment angles, draws take angle as unit.Y axle 720 comprises 723,12 ° of initial therapy angles, and for the sake of clarity it is shown as and amplifies and the border arranged.In this embodiment of the present invention, 12 ° is the setting of L5-S1 intervertebral space.DRV starts and is set to negative variance, pure oscillation, (θ _DRV)=1 °, as shown in Figure 6.

In Fig. 7 B, treatment angle 726 is vibrated with sinusoidal manner for whole treatment.

Current treatment angle 727 is presented in the square frame on Fig. 7 B the right.This demonstration 727 changes and upgrades when the treatment Angulation changes.

In Fig. 7 C, shown the pulling force 731 of measuring, it is transmitted by force cell 155 in the present embodiment of the present invention, but it can be by any load or moment of torsion sensing apparatus signal transmission.The pulling force 731 of measuring is drawn take pound as unit for y axle 730, and it is identical with scale 710.Should be noted that, according to this embodiment of the invention, even again aim in the process of (DRV) 726 in the diversity of vertebra, the pulling force 731 of measurement is identical with expection pull-up curve 711.

In Fig. 7 D, shown pulling force correction 744.Pulling force is proofreaied and correct 744 and is drawn take pound as unit for y axle 740.In the system 10 that is formed by one embodiment of the present of invention, when regulating up and down 726, pulling force is proofreaied and correct 744 and is subject to very slight impact, thereby shows not out on scale 740 when the treatment angle.In the figure, because (θ _DRV)=1 °, the variation of the pulling force of measurement is very little, and only demand motive device 170 is regulated slightly.The pulling force that variation in the design of spinal column pressure reduction device may change system 10 produces the mode that driver 170 is reacted for the change for the treatment of angle, as reflecting in the pulling force calibration trace of this particular system 10 that is used for the treatment of periodogram 7D.

Fig. 8 shows the flow chart that forms according to embodiments of the invention, has showed the algorithm that does not change the expection pulling force for by scheduled volume, the treatment angle being regulated.

This algorithm is from the initial start of spinal column pressure reduction device (step 800).As the part of system's 10 initialize routines, vertical linearity driver 148 is re-set as extreme lower position; By any passive or active encoder data of transmitting with respect to the inner or outside range unit of installing of vertical linearity driver 148, or the potentiometer data, will measure for this initial zero; As the part of system's 10 initialize routines, horizontal driver 114 is re-set as the position that produces driver 170 near pulling force; By any passive or active encoder data of transmitting with respect to the inner or outside range unit of installing of horizontal linearity driver 114, or the potentiometer data, will measure (step 810) for this initial zero.At this some place, device calculates initial therapy angle (step 820).Alternatively, device can use the Models of Absolute Distance Measurement Based device, and it does not need this device as shown in step 810, vertical and horizontal driver to be initialized.As preferably, device can be appointed the Last Known Location of vertical linearity driver and horizontal linearity driver to nonvolatile memory, thereby does not need initialization step 810.Then 10 system shows treatment angle (step 830).

Specialist can be with the minimum and maximum pulling force input of the expection that is used for spinal column pressure reduction treatment treatment computer 190 (step 840).The setting that they also can be inputted initial therapy angle and treatment time and relate to DRV is as discussing in Fig. 6.This can carry out before patient body setting steps 850 as shown in the figure, perhaps carried out after it.

Then, specialist is configured in patient 110 health on bed 100 (step 850).Upper body holder 119 is fastened to the head end 104 of bed.Kneepad 117 is placed on the below of patient's knee.Bed 100 horizontal adjustment and/or patient 110 regulate on bed 100, so that the summit of lordosis L3 250 is positioned the top at the top, center 310 of Lordosis support 112.Lower body holder 118 is connected to patient interface device 120.Then, specialist can start treatment (step 860).

Because treatment starts (step 860), treatment computer 190 must calculate suitable pull-up curve.In one embodiment of the invention, treat computer 190 and calculate pull-up curve and treatment angle curve based on the input of specialist.Treatment computer 190 determines whether that the diversity of opening vertebra aims at (step 870) again.If DRV opens, treat so computer and consider that (step 872) will appear in which part for the treatment of DRV, which kind of diversity classification, by what (θ _DRV) (step 874) and which transition process (step 876) will be for calculating.

In case the option 870/872/874/876 of DRV is assessed, treatment computer 190 calculates and carries out pulling force and treatment angle curve (step 880).In step 870, if DRV does not open, treat so computer 190 and advance to only calculating and carry out pull-up curve (step 880).

Below presented for the purpose of illustration and description certain exemplary embodiments of the present invention.But it is not exhaustive, perhaps will be limited to disclosed precise forms to the present invention, obviously, can carry out many modifications and variations under the enlightenment of above-mentioned instruction.The selection of exemplary embodiment and description are in order to explain the practical application of certain principles of the present invention and they, thereby others skilled in the art are obtained and utilize each exemplary embodiment of the present invention and their various substitutions and modifications.Scope of the present invention is limited by appended claim and equivalents thereof.
