Description

For determining the system of spinal column pressure reduction equipment treatment angle

Technical field

The present invention relates to a kind of spinal column pulling force being applied to patient with the system for the treatment of spinal column.More specifically, the present invention relates to a kind of system, pulling force is applied to the spinal column of patient by this system by the angle of certain limit, and this system dynamics ground calculates based on the position of bed/patient treatment angle and regulates.

Background technology

Physical Therapist utilizes spinal column pressure reduction to treat and treats various spinal disease, comprises intervertebral disk hernia, degenerative disc disease, sciatica, rear facet joint syndrome levy and postoperative pain.Decompression treatment stems from traditional treatment based on traction, wherein by external force (such as Physical Therapist's hands or by automated procedure), spinal column is placed in state of tension.Typically, at traditional treatments period based on traction, spinal column is in continuous print 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, in whole treatment cycle, apply various pulling force or recycle various pulling force, thus making the other loosening all muscles of spinal column and fatigue, allowing disc separation.Seamlessly transitting between the different stage that these functions provide pulling force.In tradition traction or decompression treatment, spinal column pulling force all typically keeps 30 minutes or the longer cycle.

Because spinal column is placed in state of tension, so spinal vertebrae is separated, to allow intervertebral disc to be again 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 pressure drop produced by the separation of vertebra.The other muscle of spinal column by contrary with pulling force carry out straining may unconsciously with the stretching generation adverse effect of spinal column.And sentient people (patient) may shrink spinal muscular unconsciously and/or subconsciously, as the opposing reaction to pulling force.Above-mentioned patient reaction one of them or the two all reduce the effectiveness of spinal column dragging or spinal column pressure reduction treatment.

An example of existing common spinal column pressure reduction treatment therapy system make use of the non-feedback being connected to patient via patient interface device (such as pull strap and/or patient-securing strap) provides pulling force to produce driver (any type of dynamo-electric, pneumatic, magnetic, hydraulic pressure or chemical driver).Patient lies supine is on therapeutic bed, and head is positioned at the far-end in the pulling force source of applying.Patient's upper body is fastened to the distal portion (this end of bed is from producing the source of pulling force farthest) of bed by upper body patient-securing strap.Lower body holder carries out fastening around waist, and with connecting the point of pull strap.Pulling force produces driver and exports increase or reduce to change to produce synthesis pulling force at the attached point to patient of pull strap.Utilize Linear actuator (any type of dynamo-electric, pneumatic, magnetic, hydraulic pressure or chemical driver) thus raise and reduce relative to the attached position to patient the point (treatment localizer) that pull strap pulls, thus regulating the angle of the pulling force applied.System also comprises tension measurement equipment (such as, LOAD CELLS), and it produces driver with pulling force and patient's conllinear is connected, thus pulling force tolerance is conveyed to pulling force generation driver control equipment (such as computer).Thus system operates as controlled feedback loop, thus the pull-up curve of plan can be applied to patient, and can be verified the power that reality applies by computer.But the point in the above example, pulled relative to the pull strap of the attached position to patient is fixed typically in the process applying pulling force.Because the direction pulled is the spinal column that the spinal column being both not parallel to patient is also not orthogonal to patient, and the far-end in the pulling force source of applying is positioned at due to patient lies supine's (in this example) its head, so the pulling force applied can be modeled as two force vectors, the spinal column conllinear of a force vector and patient and away from head, another force vector is perpendicular to the spinal column of patient.When patient lies prone, the direction of the horizontal component that the pulling force of applying is made a concerted effort will keep identical, but the direction of vertical component that the pulling force applied is made a concerted effort will be put upside down.

The pulling force of spinal column pressure reduction applies at a certain angle, and special angle (described angle is specific for the design of each equipment) can affect specific disc position.The change for the treatment of angle can cause decompression stress to change in the concrete position of spinal column, by the method for three dimensional FEM simulation Experiments of Machanics, and change angle in an experiment and observe the experimental techniques such as spinal column stressing conditions, can find, the position of the maximum stress of each point of spinal column is relevant with decompression angle, decompression angle is different, and maximum stress active position is different.The relation of decompression angle and location of maximum stress is, more hour, location of maximum stress is the closer to coccyx, and on the contrary, along with the increase of the angle that reduces pressure, maximum stress moves on the direction of thoracic vertebra for decompression angle.Therefore when treating, should according to the position of pathological interspinal dish, suitably adjustment decompression force application angle, makes diseased region obtain the stress that the most effectively reduces pressure.Making specialist can treat ad-hoc location damage by regulating the angle of the pulling force applied to the ability that the position that spinal column in spinal column extends positions, carrying out correct location with the position of extending spinal column and the treatment benefit of each treatment stage just can be made to maximize.

But existing decompression or traction technique, or the adjustment (the first situation) of pulling force angle is not carried out for lesion locations, or have rough focus angle orientation, but the determination of final treatment angle, clinical treatment experience is relied on to judge, by the fixation for treatment angle that machine is preset, carry out the determination (the second situation) of angle.The problem that the first situation is brought is apparent; lesion locations cannot obtain the stress that the most effectively reduces pressure; carry out drawing or reducing pressure with parallel angle (0 °; bed body level), so maximum stress is near pygostyle, in addition; without decompression angle initialization; decompression power will act on whole spinal column, and practical function in effective decompression power of focus (pathological interspinal gap) by very little, thus effective treatment of pathological interspinal gap can not be realized.The problem of the second situation is, by machine angle-data in the past or artificial set angle, although have one with reference to basis, i.e. clinical experience or laboratory data, but problem is that human spine is not equal to the desirable spine model in computer digital or textbook, due to physiology, sex, age, physique, the differences such as job specification, spinal column physiological curve all will be caused to form difference, even same patient treated on the different dates, if still apply mechanically the angle initialization of same solidification, larger deviation must be there is in its focus angle orientation, also best effect of easing stress cannot be obtained by causing.And the present invention can after patient adjusts position, by the displacement transducer of configuration level direction and vertical direction, according to the displacement data of sensor passes, in conjunction with the HPT optimum fit curve of human vertebra, automatically the most suitable pulling force angle acting on vertebra L3 and answer is calculated, owing to located L3 more accurately relative in old scheme, L1-L5 thus also can carry out relative accurate angle relative to old scheme and located, reach lesion locations angle orientation more accurately, and then more accurately decompression masterpiece can be used for lesion locations.

Summary of the invention

The present invention attempts to show a kind of unique method, and comprehensive various patients and anthropometry locate lordotic summit (the 3rd vertebra of lumbar vertebra) on spinal column pressure reduction therapeutic bed.In addition, utilize lordotic summit and be positioned at the initial point that rumpbone place is applied to the synthesis pulling force of patient, to calculate the sections treatment angle based on average or desirable spine model, described model considers the horizontal level of therapeutic bed and the upright position for the treatment of localizer.

Usually, the point that the lower spinal column of different patient does not need pull strap to pull is in identical position in the horizontal direction.Therapeutic bed of the present invention is designed to slide towards with the point that can pull away from pull strap, to adapt to the difference of patient's height.No matter and the height of patient how, the position of lower spinal column is known.This is realized by two kinds of modes.

First, by placing Lordosis support in therapeutic bed, it plays the effect of lordosis laying-out curve same position on therapeutic bed of patient's spinal column.Specifically, lordotic summit, third lumbar vertebra (L3), is positioned at the top of the center top of Lordosis support.Lordosis support can be the raised position in a body, such as foam protruding part, or can be adjustable support member, such as inflatable pneumatic mattress.Lordosis support is used for two objects, and all allow equipment to calculate treatment angle based on the known location of lordosis spinal column, and be used as fulcrum, lower spinal column is aimed at about this fulcrum and extended.

Secondly, by inserting position sensor in therapeutic bed, it detects movement and the position of therapeutic bed.Therapeutic bed utilizes Linear actuator to move horizontally towards with away from pulling force source to make therapeutic bed.Position sensor for this applying can be positioned at the potentiometer of driver, relative or absolute encoder, or optical device.Position sensor also can be installed on driver outside.Under any circumstance, the tolerance being positioned at horizontal stretcher bed position sensor is conveyed to processing unit, is used for the treatment of the dynamic calculation of angle.

According to above-described two kinds of methods, no matter highly how patient changes, and can be known relative to the horizontal level on the summit of the lordosis of the spinal column in pulling force source.

In normal traction and spinal column pressure reduction equipment, pulling force source is generally fixing in the horizontal direction away from the position of patient.Pulling force source can raise relative to patient in vertical direction and reduce, to increase and to reduce to be applied to the angle of the pulling force of patient.Selectively, suitable position can be fixed in vertical direction relative to patient in pulling force source.In this scenario, the point that roll system pulls to raise and to reduce pulling force source relative to patient can be utilized, to increase and to reduce to be applied to the angle of the pulling force of patient.In either case, the point that the driver of some types pulls to raise and to reduce pulling force source or pulling force source is utilized.Position sensor being built in the driver of the upright position controlling the point that pulling force source or pulling force source pull, this providing the upright position tolerance of the processing unit for using in the dynamic calculation for the treatment of angle.

Synthesis pulling force vector starting point is positioned at the rear side rumpbone place at health by lower part of the body patient-securing strap, thus makes the change for the treatment of angle directly affect this spine structure.If initial point is positioned at the patient's waist on rear side of health above rumpbone, so may have to consider patient's waistline when calculating treatment angle.It is known that for lumbar vertebra in the technology of spinal column pressure reduction, the reference of the initial tensile force of spinal column is 1/2nd of weight in patients.And this pulling force rank is at least enough to make spinal column loosen and makes spinal column promote by treatment angle and rotate.

The present invention proposes a kind of device that spinal column is suitably loosened, then just specify suitable intervertebral disc treatment angle.For lie on the back or prostrate on therapeutic bed, lie on one's side position or the patient that stands design spinal column pressure reduction equipment, need to select suitable radiographic data.Such as, utilize the radiography carried out the standing patient of spinal column load gravity to measure may to be not suitable for the equipment for having patient's design of kneepad below the knee in bed of lying on the back.If patient lies supine, have kneepad below its knee, this makes to utilize ideal or average mean segment lordosis to measure TA angle.Can consider to use the sections based on the patient suffering from back pain to measure.

Treatment angle calculation is by carrying out visual carrying out to the triangle formed by three points.These three points define leg-of-mutton limit, and length that is vertical and horizontal component allows to calculate the treatment angle being initial point with the summit of lordosis.

The point (or being then the point that pulling force source pulls in vertical direction relative to patient when vertical fixing pulling force source) that pulling force source is in vertical direction relative to patient defines the vertical height above some starting points.This starting point is in the point in the vertical plane divided equally in the horizontal direction by the center top of Lordosis support.Distance between 2 forms the vertical dimension for the treatment of angle calculation.

The distance of the center top (being equal to the summit of lordosis) from above-mentioned starting point to Lordosis support forms the horizontal range for the treatment of angle calculation.

The treatment angle stemming from lordotic summit can by utilizing arctan function to calculate:

Wherein opposite side is vertical dimension, and adjacent side is horizontal range.

The upright position (when making the horizontal level of bed fix) of the point that increase pulling force source or pulling force source pull can increase the value for the treatment of angle.The horizontal level (when making the upright position in pulling force source fix) changing the some distance therapeutic bed pulled towards pulling force source or pulling force source can increase the value for the treatment of angle.

The upright position (when making the horizontal level of bed fix) of the point that reduction pulling force source or pulling force source pull can reduce the value for the treatment of angle.The horizontal level (when making the upright position in pulling force source fix) changing the some distance therapeutic bed pulled away from pulling force source or pulling force source can reduce to treat the value of angle.

The present invention utilizes the tolerance coming from vertical and level sensor, particular patient location and patient positioning, and radiography spinal column is measured, and carrys out dynamic calculation treatment angle.

Fig. 7 A and Fig. 7 B is two views of lower spinal column (700 and 701) respectively.Fig. 7 A shows to treat angle 790 and additionally applies to synthesize the spinal column before pulling force vector F702.Fig. 7 B shows the spinal column applied after described synthesis tensile force f 702.

HPT tangent line 720,730,740,750,760 and 770 is plotted as after vertebral body S1710, L5711, L4712, L3713, L2714 and L1715.

F702 drives lower body holder 118 to be applied to patient 110 by patient interface device 120 with joint efforts.According to the specific explanations provided in Fig. 4, lower patient-securing strap 118 is designed to produce synthesis pulling force vector F702 at the base portion place of rumpbone 710, is in the below of supine patient 110 in this embodiment of the invention.When being decomposed into vertical component Fy704 and horizontal component Fx703, synthesis pulling force vector F702 acts on lower spinal column 700/701 in two ways.First, vertical component Fy704 can be regarded as the lifting from rumpbone 710, the opposing of lordosis summit the 3rd vertebra L3713 above the center top 510 being subject to Lordosis support 112.Horizontal component Fx703 can be regarded as pulling all aligning spinal segments, extends to make spinal column.

In fig. 7, spinal segments 710,711,712,713,714,715 and 716 does not have zero sections angle (aligning), because there is no External Force Acting on spinal column, and suppose that nature lordosis more or less can be present between all sections of spinal column under patient.If a bit all there is no nature lordosis in lower spinal column 700, and simultaneously not from then not convex, so except zero degree just without any need for treatment angle.

In figure 7b, 702 act on lower spinal column with joint efforts.By patient interface device 120 by lower body holder 118,702 act on vertebral levels S1710 with joint efforts.As general guilding principle, the size of synthesis pulling force 702 is set to 1/2nd of weight in patients, this is the convention of this area, but specialist has a responsibility for adjusting its size to be made it be enough to promote the lower part of the body and rotates patient's lower part of the body, rumpbone/pelvis/buttocks to correct position.Vertebral levels S1710 is made to promote relative to subordinate's soleplate of L5711 and rotate according to the vertical component Fy704 synthesizing pulling force 702.The angle 790 of the applying of synthesis pulling force 702 is θ ₁-θ ₀, 730-720, it is enough to make the rear side of vertebral body S1710 and L5711 parallel to each other, thus " aligning ".Once vertebral body S1710 and L5711 aims at, intervertebral disc leading edge and trailing edge are all depressurized 780.Along with synthesis pulling force 702 circulates between minimum and maximum level, vertebral body S1710 and L5711 also aims at or misalignment thereupon.

The aligning of vertebral body S1710 and L5711 and misalignment cause the disorder of the other muscle of spinal column and loosen, particularly when synthesis pulling force 702 circulates smoothly.In addition, because occur that the process of Hui Na is vertebral body Mechanical Moving relative to each other, described by the aligning of described vertebral body and misalignment, the aligning of vertebral body S1710 and L5711 and misalignment cause receiving increase returning of basivertebral soleplate place intervertebral disc.In addition, the elongation 780 of having aimed at vertebral body S1710 and L5711 causes the decline of the dmm of extended position, and then causes vertebral pulp to move in spinal column.

Fig. 8 A and 8B is two views of lower spinal column (800 and 801) respectively.Fig. 8 A shows to treat angle 891 and additionally applies to synthesize the spinal column before pulling force vector F802.Fig. 8 B and Fig. 7 category-B seemingly, have rotated angle 890 and have extended distance 880.Fig. 8 B shows the spinal column applied after described synthesis tensile force f 802.

HPT tangent line 830,840,850,860 and 870 is plotted as after vertebral body L5811, L4812, L3813, L2814 and L1815.

The lower body holder 118 that F802 is connected by patient interface device 120 is with joint efforts applied to patient 110.According to the specific explanations provided in Fig. 4, under patient, body holder 118 is designed to produce synthesis pulling force vector F802 at the base portion place of rumpbone 810, is in the below of supine patient 110 in this embodiment of the invention.When being decomposed into vertical component Fy804 and horizontal component Fx803, synthesis pulling force vector F802 acts on lower spinal column 800/801 in two ways.First, vertical component Fy804 can be regarded as the lifting from rumpbone 810, the opposing of lordosis summit the 3rd vertebra L3813 above the center top 510 being subject to Lordosis support 112.Horizontal component Fx803 can be regarded as pulling all aligning spinal segments, extends to make spinal column.

In fig. 8 a, S1810 and L5811 is only had to aim at, as described in Fig. 7 B.Other spinal segments 811,812,813,814,815 and 816 does not have zero sections angle (aligning), because making a concerted effort 702 is act on epispinal with the treatment angle only enough making 810 and 811 to aim at., and suppose that nature lordosis more or less can be present between all sections of patient's 110 times spinal columns in addition.If a bit all there is no nature lordosis in lower spinal column 800, and simultaneously not from then not convex, so except zero degree just without any need for treatment angle.
