Three-dimensional Spine Remedying Apparatus
Field of the Invention
The present invention relates to medical appliances for
treating parenchyma trauma between vertebras and, in particular, to
a therapeutic apparatus for remedying three-dimensional
displacements between vertebras.
Background of the Invention
Diseases with parenchyma trauma between vertebras, such as
prolapse of lumbar intervertebral disc, cervical spondylopathy and
thoraxlumbar rear joint disorder, are familiar diseases which bring
tremendous suffering to the patient. Medication is not efficacious to
these diseases. In addition, the cost of operation is high, while the
patient has to endure the long operation and tremendous suffering
thereafter. Therefore, the applicable scope of operation is limited.
Remedying apparatus for treating these diseases have been
widely used. For example, many types of traction apparatus have
been developed. However, all the existing traction apparatus adopts
linear traction, only in one direction. Since it not can remedy the
angular displacement between the vertebras, the curative effect is not
ideal. Further, the process of draught is usually performed by
manual labor, or by hydraulic or mechanical transmission, and the
draught velocity is low, and the patient may feel uncomfortable in
the process of draught, which has an adverse effect on the treatment.

CA 02288894 2003-12-08
In addition, trauma would be caused when the distance of draught
exceeds the limit because of misoperation.
The inventor of the invention has found that, for prolapse of
lumbar intervertebral disc and cervical spondylopathy, the
displacements between the affected vertebras usually occur -in three
dimensions. That is, linear displacements and angular displacements
may occur along the longitudinal axle, lateral axle and vertical axle
between the upper vertebra and the lower vertebra, so that the stress
between the vertebras is changed to break the stable and coordinate
state. Therefore, not only the fibre rings are broken and the nucleus
pulposus protrudes due to the unevenly distributed forces, but also
the rear joint, and the muscles and ligaments attached thereto or the
nerves and blood vessels nearby are affected. This makes the patient
suffer from pain in the neck, shoulders, waist and legs. As time
passes, to compensate for the above situation, hyperosteogeny and
ligament pachismus will appear at the positions to bear larger force
with more serious consequence. The inventor has thus come to see
that it is necessary to remedy the lineal displacements and the
angular displacements between the vertebras in three dimensions
rather than to correct the lineal displacements in one direction alone.
Only in this case is it possible to remedy the misalignment among
small joints between the vertebras, and to eliminate the abnormal
draught, squeeze or stimulation on the muscles, the ligaments, the
nerves and the blood vessels nearby, so that the structure between
the vertebras can be restored from a state of bearing uneven forces to
a natural and coordinate state.

CA 02288894 2003-12-08
Based on the pathology described above and the rich
experience in bone setting accumulated over the years, the present
inventor has filed an application titled "Angulate Rotating Multi-
functional Draught Bed ", which has been granted a Chinese patent
(CN206 464 3U) and a Japanese Patent (Patent number: 95'-79823).
Said draught bed comprises: a frame, a cephalothoracic board, a hip-
leg board, a draught device, a device for the horizontal rotating of
said boards, a device for the vertical rotating of said boards and a
control device. Said cephalothoracic board is driven by said draught
device to move horizontally along the longitudinal axle of said
draught bed. Said hip-leg board can swing around the lateral axle (Y)
of said bed to form a certain angle with the vertebra's longitudinal
axle. Furthermore, said hip-leg board is able to rotate to the left or
the right around the longitudinal axle (X) of said bed to twist the
vertebras. It is verified by clinical applications that the curative
effect of said draught bed for treating prolapse of lumbar
intervertebral disc is fairly good.
Although the hip-leg board of the said patented draught bed is
capable of rotating around the longitudinal axle (X) and the lateral
axle (Y), it still cannot rotate around the vertical axle (Z).
Accordingly, the vertebra twisting in that direction has to be
corrected manually. Furthermore, because the movement mechanism
is hydraulically driven or mechanically driven, the speed is relative
low. This makes the patient uneasy when being treated: In addition,
the noise of the hydraulic driving is loud and not suitable for medical
to the environment of medical treatment . Also, because the high-
speed traction and the low-speed traction of the patented bed are
3

CA 02288894 2003-12-08
transmitted separately, and the bed is not convenient to medical
treatment. In addition, said hip-leg board can rotate to only one side
each time when said draught bed is rotating around the longitudinal
axle, and it takes a lot of time for the board to rotate to the other side.
Said draught bed not can move between the two sides quickly and
repeatedly. Hence, there is no function provided for releasing the
tension of the muscles surrounding the vertebras, and it is adverse to
the treatment of the strain of lumbar muscles and the alignment of
the vertebras.
Objects of the Invention
The object of the present invention is to further improve the
Chinese Patent CN2064643U "Mufti-functional Draught Bed", and
to provide a three-dimensional spine remedying apparatus, which
has a better curative effect and more convenient operation and
makes the patient feel safe and comfortable during the treatment.
Said Chinese Patent CN2064643U is the most relative
document of the present invention, which is entirely based on the
disclosure of the foregoing patent.
Summary of the Invention
The three-dimensional spine remedying apparatus of the
invention comprises the following devices: a frame for mounting
mechanisms and driving devices of said apparatus; a cephalothoracic
board, which is fixed on said frame, for supporting and securing the

Description of A Preferred Embodiment of the Invention
The preferred embodiment of the present invention will be
described with reference to the drawings. It should be understood
that the embodiment is only to illustrate the invention, not to limit its
scope. The scope of protection of the invention should be defined by
the appended claims.

CA 02288894 2003-12-08
Figure 1 is a perspective view of an embodiment of the three-
dimensional spine remedying apparatus of the present invention. In
figure 1, reference number 1 denotes the case-shaped frame on
which all the components of the apparatus are mounted. The electric
control device (not shown) of the apparatus may be arranged on
either side of the frame. As shown in figure l, the patient lying face
down on the apparatus is being treated.
Now referring to figure 2, the cephalothoracic board device 2
is arranged on the frame 1, wherein the cephalothoracic board 201 is
supported by four wheels 21, which move along the rails on the
frame 1. The magnetic driving device 7 for moving the
cephalothoracic board device 2 horizontally along the axle X is
positioned centrally above the frame l, below the device 2.
The hip-leg board device 3 is composed of a hip-leg board 31,
a bow shaped shelf 32 and a long frame 33. The hip-leg board 31 is
fixed on the long frame 33. The long frame 33 which is connected
with the shelf 32 by two hinge axes 36 can rotate around the axle X.
The shelf 32 is able to rotate around the axle Y with its left end
mounted on the frame 1 by the hinge axle 3S. The lower portion of
the shelf is supported on the driving device 4 by a pintle 34. Said
driving device 4 consists of a swaying hydraulic cylinder or an air
cylinder 41. When the plunger 42 is extending or retracting, the
shelf 32, i.e. the entire hip-leg board device 3 is driven to rotate
around the axle Y by a certain angle.
The reference number 5 denotes the driving device 5, which
is mounted inside the bow shaped shelf, for rotating said long frame
33 and said hip-leg board 31 around the axle X. The reference
s

CA 02288894 2003-12-08
number 6 denotes the hip board device which is mounted on the Iong
frame 33 with a hip board 601 on the top, the upper face of the hip
board is flush with that of the hip-leg board 31. The hip board 601
mounted on the long frame 33 can rotate around the axle Z, and is
driven by the hip board's driving device 60. The description and the
working process of the hip-leg board device 3 and the hip board
device 6 as well as the driving devices thereof are to be followed.
The reference number 8 in figure 2 denotes the device for
adjusting the degree of tightness of the securing device for securing
the body of the patient, which will be described in detail.
The reference number 9 denotes the low-speed draught
device, and the reference number 10 denotes the hook for draughting.
In the draught device 9, a motor 91 drives the winding drum in the
rolling device 92 to rotate and, subsequently, the hauling rope 94 is
dragged through a pulley 93. As a result, the hook 10 fixed on the
free end of the hauling rope 94 is able to draught the headgear (not
shown in the figure) which is attached to the head of the patient, i.e.
draught the vertebra cervicalis at a low speed. In addition, the
bracket 96 for installing the first pulley 93 can move along the axle
X on the slide rail of the frame I (not shown in the figure). However,
the further leftward movement of the bracket 96 is stopped by the
limit stop 97 mounted on the frame 1.
Now, the structures of the driving device of the
cephalothoracic board device 7 and the high-low speed linking up
clutch for linking up the movement between the low-speed draught
device and said driving device are to be described with reference to
figure 3.
9

CA 02288894 2003-12-08
The reference number 71 in figure 3 is a box shaped case, the
dextral bottom of which is open. Some wheels which can move
along the axle X on the slide rails of the frame 1 are provided on
both sides of the case 71. The immovable electromagnet 72
positioned on the right-hand side of the case 71 is fixed on the frame
1 by a bolt, while the movable permanent magnet 73 which can
move relative to the immovable electromagnet 72 is fixed on the
left-hand side of the case 71. The reference number 74 denotes a
compression spring. When the electromagnet 72 is not electrified,
the permanent magnet 73 moves rightward to the electromagnet 72
due to the magnet attraction therebetween, and thus compressing the
spring 74. When the electromagnet 72 is electrified, the polarities of
the two magnets shown in figure 4 are repelling each other. As a
result, the permanent magnet 73 fixed in the case 71 moves leftward
along with the case. Since the electromagnetic force is generated
rapidly and the force of the spring 74 and the electromagnetic force
are in the same direction, the case 71 moves leftward at an
accelerated speed. Alternatively, said permanent magnet 73 can be
replaced with an electromagnet on condition that the same polarities
of the two electromagnets are face to face as the repelling effect of
the two electromagnets is required.
The reference number 74 in figure 3 denotes a pin which
passes through the permanent magnet 73 into the case 71 and can
slide along the axle Z within the case 71. When the cephalothoracic
board device 2 is required to move leftward quickly, the spring 76 at
the bottom of the case 71 jacks up the flange 77 at the lower end of
the pin 74, making the upper end of the pin 74 inserted into the hole

CA 02288894 2003-12-08
on the limit stop 75, which is fixed on the cephalothoracic board 201.
And then, the body of the patient is rapidly draught leftward along
the axle X by the cephalothoracic board device, so as to treat
diseases such as prolapse of lumbar intervertebral disc.
The reference number 711 in figure 3 denotes a baffle which
is oriented by the guide rail on the frame 1 and used to limit the
distance of the leftward movement of the case 71, i.e. of the
cephalothoracic board device 2. A screw 712, which is screwed into
the bolt hole in the rear of the baffle 71 l, is driven by the motor 713,
so as to adjust the movement distance of the baffle 711, i.e. of the
cephalothoracic board device 2. In this way, a precise hauling
distance is ensured without injuring the patient.
In order to prevent the case 71 from rebounding after it
knocks against the baffle 711, an arresting device including a case
721 fixed on the lower portion of the baffle 711 is provided. Said
case 721 includes a small electromagnet 722 mounted on its bottom,
a ferromagnet 724 below the stopper 723, a compression spring 725
positioned between the ferromagnet 724 and the electromagnet 722,
wherein the spring 725 is used to push up the stopper 723. Both the
upper right edge of the stopper 723 facing the case 71 and the lower
left edge of the case 71 are chamfered to a round corner. When the
case 71 moves toward the baffle 711, its lower edge contacts with
the upper edge of the stopper 723, and the stopper 723 is forced to
move down by means of the round corners on both sides against the
spring 725. When the case 71 passes the stopper 723, the stopper
723 is pushed up by the spring 725 and enters into the recess 726 on
the case 71 to limit the movement of the case 71. In this way, the

CA 02288894 2003-12-08
rebounding of the case 71, i.e. of the driving device 7 of the
cephalothoracic board, is prevented. When the case 71 is required to
move back, the electromagnet 722 is electrified so that the stopper
723 is forced down and exits the recess 726, hence the case 71 is
reset automatically via the magnetic force of the permanent iriagnet.~
The structure and the working process of the high-low speed
linking-up clutch for linking up the movement of said high-speed
magnetic driving device with that of said low-speed draught device
9 will be described hereinafter.
The working process of the low-speed draught device 9 has
already been described above. Said clutch is needed when the hook
is required to speed up suddenly in the draughting process. Said
clutch is composed of an electromagnet 731 fixed in the case 71 and
a lever 733 which is pivotally connected with a column fixed on the
bottom of the case 71. A ferromagnet 732 is fixed on the right end of
the lever 733 and a fork 734 is fixed on the left end. The notch in the
middle of the fork 734 is clamped on the sides of the pin 74 , with
the lower face of the fork 734 pressing against the upper face of the
flange 77 on the lower portion of the pin 74. In addition, a slide
block 735 which can move on the slide rail of the frame along the
axle X is placed below the case 71. A pinhole for accommodating
the pin 74 is provided on the slide block 735. Under the non-
operating state, the hauling rope 98 draughts the slide block 735 to
the right by means of a tension spring 95, forcing said slide block
735 to lean against a distance piece. In this state, the pin 74 is
aligned exactly with the hole on the slide block 735. If the
electromagnet 731 is electrified at this time, it will attract the
iz

CA 02288894 2003-12-08
ferromagnet 732 upwards, causing the Iever 733 to rotate around its
pivot. So, the flange 77 of the pin 74 is pushed down by the fork 734
at the left end of the lever, and the lower end of the pin 74 is forced
into the hole of the slide block 735 when the elastic force of the
spring 74 is overcome.
When the draught force of the low-speed draught device
reaches a predetermined value, the immovable electromagnet 72 is
electrified, and then the high-speed driving device of said
cephalothoracic board begins to work, so that the permanent magnet
73 moves to the left rapidly. However, the slide block 735 is being
driven this time instead of the cephalothoracic board device 2. As a
result, the slide block 735 drives the slide plate 96 rapidly to the
right by using a pulley (refer to figure 2) and a hauling rope around
the pulley, so that the hook 10 which is moving slowly suddenly
speeds up. This is especially suitable for treating cervical
spondylopathy.
Now, the structures and working processes of the hip-Ieg
board device as well as the device for rotating said hip-leg board
device around the axle X will be described with reference to figure 5.
In figure 5, an oscillating lever S 1 is mounted below the hip-
leg board 31 which is fixed on the long frame 33. At the lower end
of the oscillating lever 51 is a long slot in which a pin 52 is inserted
and capable of freely sliding up and down. The reference number 53
denotes a ferromagnet moving along the axle Y, in which said pin 52
is mounted. When the ferromagnet 53 moves left and right along the
axle Y, the hip-leg board 31 and the long frame 33 supported by the
hinge axle 36 rotate around the axle X due to the relative slide
13

CA 02288894 2003-12-08
between the pin 52 and the long slot at the lower end of the
oscillating lever 51.
Said ferromagnet 53 is driven by two electromagnets 54
arranged at both sides of it. Two nuts 56, 57 are separately fixed at
the lower end of each electromagnet 54 and connected with a lead
screw 55, wherein the helical directions of the nuts 56 and 57 are
opposite, and so are those of the threads at the two ends of the lead
screw 55. Said lead screw 55 is mounted on the abutments of the
slide plate 59 and driven by the motor 58 on the rightside. By
starting the motor 58 to rotate the lead screw 55, the space between
the two electromagnets 54 and the ferromagnet 53, i.e. the sway
angle a of the hip-leg board 31, is adjusted. In addition, the slide
plate 59 can be driven by the lead screw which is turned by another
motor 58 on the left side, so that the slide plate 59 can slide along
the axle Y. When the slide plate 59 moves to the right, the left
electromagnet 54 comes closer to the ferromagnet 53, whereas the
right electromagnet 54 departs from the ferromagnet 53, and vice
versa. At this time, the sway angle a of the hip-leg board 31
remains unchanged, but the angle of its sway between the two sides
is different.
If one of the electromagnets 54 is electrified, the ferromagnet
53 will be attracted, and the hip-leg board 31 will sway toward one
side and then stay on that position. If both electromagnets 54 are
electrified with impulse current alternately, the hip-leg board 31 will
sway from side to side successively (angular oscillation), wherein
14

CA 02288894 2003-12-08
the frequency of the oscillation depends on the frequency of the
impulse current.
The swaying of the hip-leg board 31 in a certain direction is
able to correct the angular displacement between the vertebras,
whereas the continuous swaying between the two directions (angular
oscillation) is able to relax the muscles, and further to treat diseases
such as the strain of lumbar muscles.
Now, according to figures 6 and 7, the structures and working
process of the hip board device 6 and the device 60 for rotating the
hip board device 6 around the axle Z will be described. It should be
noted that figure 6 is an upward view.
The reference number 61 in figure 6 denotes a ferromagnet,
on both sides of which two electromagnets 62 are arranged
separately. Similar to the structure and the working principle of the
magnetic mechanism in said driving device 5, two nuts having
opposite helical directions are separately fixed on two
electromagnets 62 and driven by a lead screw 63 which is turned by
a motor 64, so as to adjust the distance between the ferromagnet 61
and the two electromagnets 62 simultaneously. In addition, the entire
driving device 60 is mounted on the long frame 33 of the hip-leg
board device 3.
Referring to figure 7, the reference number 65 denotes a
swing rod, one end of which is fixed on an axle 66 by using a key or
other means. And said axle 66 is welded on the lower surface of the
hip board 60I, and is supported by a bearing 67 installed in the long
frame 33. The lower surface of the hip board 601 is a slightly higher
than the upper surface of the long frame 33, and the hip board 601 is
~s

CA 02288894 2003-12-08
supported by several trolleys 681 or roller bearings mounted in the
long frame 33. A long slot 69 is notched at the other end of the
swing rod 65, and a pin fixed on the ferromagnet 61 extends upward
into the long slot 69, in which the pin can move in relation to the
swing rod 65. In addition, the ferromagnet 61 is provided with
trolleys 68 on both sides which are supported by the rails on the long
frame 33 and can roll on said rails.
Similar to the driving device 5, if only the electromagnet
62 at one side of the ferromagnet 61 is electrified, the
ferromagnet 61 will be attracted by the electromagnet to shift
toward it. At this time, the swing rod 65 is driven by the pin on top
of the electromagnet 61 which is inserted into the long slot 69, and
accordingly drives the axle 66, i.e. the hip board 601, to rotate
around the axle Z. when the electromagnets 62 at both sides of the
ferromagnet 61 are electrified with impulse current alternately, the
ferromagnet 61 drives the swing rod 65, the axle 66 and the hip
board 601 to sway left and right (angular oscillation), wherein the
frequency of the oscillation depends on the frequency of the impulse
current.
Also, the rotation of the hip board 601 in one direction is
used to remedy the angular replacement between vertebras, whereas
the continuous vibration (angular oscillation) of the same is used to
relax the muscles, and further to treat diseases such as the strain of
lumbar muscles.
Figure 8 illustrates the adjusting devices 8 which are
mounted on the back of said plates 2, 3I and 6 for adjusting the
degree of the tightness of the securing belts and the positions of the
16

CA 02288894 2003-12-08
slot holes 81 by which the securing belts pass through the
cephalothoracic board 2 and hip board 601.
Figure 9 is a structure chart of the adjusting device 8. A lead
screw 83 is mounted on the driving axle of the motor 82 and a nut
84 is mounted on said lead screw 83. In addition, a rope pulley 85 is
mounted on the nut 84 and it can move along with the nut. A taut
wire 87 passes by the rope pulley 85 and two immovable rope
pulleys 89. The two free ends of the wire 87 are fastened to one side
of two connecting plates 86 and the securing belts 10I are connected
with the other side of the connecting plates. The other end of the
securing belts 101 connected with the securing belt on the other side
shown in Figure 1 or other taut pieces after passing through the gap
of the TI shaped plates 88 and the slot holes 81 shown in Figure 8.
The lead screw 83 begins to rotate when the motor 82 is
started and drive the nut 84 together with the rope pulley 85
mounted thereon to move leftward. And then the two ends of the taut
wire 87, which are connected with the connecting plates 86, move
rightward, so that the securing belts 101 are fastened enough to
secure the torso of the patient. When the motor 82 rotates in the
reverse direction and drives the nut 84 and the rope pulley 85 to
move rightward, the securing belts will be loosened. However, since
the width of the connecting plate 86 is larger than that of the gap in
the middle of the TI shaped plate 88, the securing belt 101 is able
to loosen to such an extent as permitted by the IZ shaped plate 88.
Figure 10 is a block diagram showing the electric control
system, under which all the working mechanisms of the present
m

apparatus can be controlled by a microcomputer, which is
advantageous to the course of treatment.
Industrial Application
The apparatus of the present invention is an improvement on
the prior art considering that the pathological change between
vertebras is often three-dimensional, with the linear displacement
and the angular displacement occuring synchronously. Moreover,
according to the principle of the physiology, the faster the speed of
the stimulation to the muscles and the nerves within the range of
safety, the lighter the degree of suffering. Known from the medical
practice, the faster the speed of the draught (linear displacement) and
the angular displacement, the higher the instantaneous negative
pressure between the vertebras, and the higher the pressure between
the rear ligament and the intervertebral disc, which is in favor of
reposition or replacement, and the relieving of the conglutination
between the nerve roots and the surrounding tissues. Therefore, the
apparatus of the present invention has excellent curative effect for
parenchyma trauma between vertebras such as prolapse of lumbar
intervertebral disc and cervical spondylopathy. In addition, the
apparatus can also be used to treat strain of lumbar muscles.
Compared with the prior art, the apparatus of the invention
includes the following advantages:
1. Since the apparatus of the present invention can not only
draught along the axle X, but also have the hip-leg board and the hip

CA 02288894 2003-12-08
board rotate around the three axle (X, Y, Z). Therefore, it may be
used to treat pathological changes in various positions, which would
improve the curative effects.
2. Since an electromagnetic driving device is adopted in the
apparatus of the invention, the draught speed is much faster than
hydraulically or mechanically driven device, wherein the time of the
draught process can be less than 0.1 second. As a result, the patient
would not be uncomfortable or frightened in the treatment process,
and thus the curative effects would be improved.
3. Since devices for presetting distance are provided in all
high-speed driving devices, the draught distance and the angle of
swing are limited in the range of safety and efficiency. Therefore the
extension of the parenchyma attached to vertebras, such as ligaments
or muscles, would not exceed the limitation (usually is 4~7 mm) , so
that the parenchyma would not be injured. So the apparatus of the
invention is absolutely safe to the patient.
4. A high-speed driving mechanism and a low-speed driving
mechanism are provided in the linear draught driving device of the
cephalothoracic board device. Furthermore, the motions of said two
mechanisms are linked up by a clutch device. In addition, the hip-leg
board and the hip board can be driven to make a rapid vibration by
the driving devices thereof, wherein the vibration can relax the
muscles. Therefore, the apparatus of the invention can imitate the
massage for bonesetting in traditional Chinese medical science and
replace the manual massage. In addition, the velocity, distance and
angle of the motions in all the mechanisms are adjustable and can be
controlled by computer, so that the problem of how to determine the
19

CA 02288894 2003-12-08
strength and magnitude of the massage in Chinese traditional
medicine is properly solved.
5. Since a device for securing the body of the patient is
provided, and the tightness and adjusting of the securing belt can be
controlled by mechanism and computer, and the strength of the
securing is limited within a suitable range.
6. The noise of the electromagnetic driving is low and
transient, which is suitable for treatment.
