In the present invention, as the permanent magnet, various conventionally known materials can be used. In particular, in order to most effectively realize the object of the present invention, rare earth - cobalt magnets or Fe-BR magnets are used. It is desirable to use a magnet having excellent magnetic force even in a small shape, such as a magnet. It is desirable that the shape and size of the permanent magnet be appropriately selected depending on the required magnetic repulsion, the shape and size of the magnet holder, and the like.

Further, when the permanent magnet comes into direct contact with the inside of the human body, it is easily corroded, and it is necessary to perform a corrosion prevention treatment on the surface of the permanent magnet. Considering the influence on the human body by permanent magnets such as Sm, Nd-Fe-B, etc., as shown in the examples described later, with a corrosion prevention cover made of stainless steel, titanium, cobalt chromium, vitalium, ceramics, and silicon. It is desirable to surround the surface.

However, when a magnet holder having a structure for sealing a permanent magnet is employed, it is only necessary to provide a corrosion prevention film of aluminum, silicon or the like.
Naturally, it is also desirable to use a corrosion prevention film and a corrosion prevention cover together.

The magnet holder needs to be made of a non-magnetic material in order to effectively realize the function of the permanent magnet and to facilitate the work of disposing the permanent magnet. As a means for fixing the magnet holder to the vertebral body, various instruments commonly used for treatment can be adopted, but when the fixing work to the vertebral body and the like are taken into consideration, the magnet holder is arranged on the magnet holder as shown in the embodiment described later. It is desirable to use screws or flanges. Further, it is necessary to select a material in consideration of the influence on the human body as in the case of the permanent magnet, and usually, stainless steel, titanium, cobalt chromium, vitalium, ceramics and the like are desired.

The shape and size of the magnet holder are desirably selected in consideration of the shape and size of the permanent magnet to be arranged, the means for fixing to the vertebral body, and the like. Various arrangements are adopted in the arrangement movably in the axial direction, as will be described later in embodiments. In any case, this magnet holder aims at the function of holding the permanent magnet, but depending on its shape, it surrounds the entire permanent magnet and also has the function of protecting the permanent magnet.

As described above, the magnetic therapy device for treating scoliosis of the present invention can adopt various forms according to the symptoms and the like. The present invention is not limited to the configuration of the embodiment, and any configuration can achieve the object of the present invention as long as it satisfies (essential requirement).

And the screw 13. FIG. 2 shows a configuration in which the permanent magnet support 12 and the screw 13 are integrated, but each may be composed of an independent member .

Reference numeral 15 denotes a corrosion prevention cover made of stainless steel or the like surrounding the permanent magnet 14. One end (inner end surface) of the corrosion prevention cover 15 has a convex curved surface, and is in contact with a magnet movement adjusting member 16 having a thickness T. That is, after the magnet structure 10 is fixed to the vertebral body (not shown) via the screw 13, the distance Lg between the magnetic poles of the adjacent magnet structure and the permanent magnet is adjusted (see FIG. 1). The magnet moving amount adjusting member 16 is inserted from the adjusting member insertion opening 17 opened on the upper surface of the magnet supporting portion 12 along the side surface of the partition wall 18 located at the center of the permanent magnet supporting portion 12, and the permanent magnet 14 is placed.

The distance Lg between the permanent magnet magnetic poles of the body can be adjusted, and an optimal repulsion can be obtained.

The one end (inner end surface) of the corrosion prevention cover 15 is formed as a convex curved surface. In the magnet holder 11, the opposing surfaces of the pair of permanent magnets 14 and 14 become different magnetic poles via the partition wall 18. The permanent magnet 14 is not necessarily inserted only by inserting the magnet movement amount adjusting member 16.
However, in order to solve this, the shapes of the corrosion prevention cover 15 and the magnet moving amount adjusting member 16 are devised. However, in order to adjust the moving amount of the magnet, several kinds of the moving amount adjusting members 16 having different thicknesses T are installed in advance, and a predetermined number of the moving amount adjusting members 16 are removed as necessary.

By adjusting the amount of rotation of the magnet, it is possible to adjust the protrusion amount t of the permanent magnet 24 from the permanent magnet support portion 22 and adjust the distance Lg between the permanent magnet magnetic poles of the adjacent magnet structures. An optimal repulsion can be obtained.

In this configuration, both the screw portion 27 formed on the outer peripheral surface of the corrosion prevention cover 25 and the screw portion 26 formed on the inner peripheral surface of the permanent magnet support portion 22 have an outer peripheral surface and an inner peripheral surface which are not shown. The same effect can be obtained even if the threaded portions 27 and 26 are formed at predetermined positions on the surface or over the entire surface.

Embodiment 3 FIG. 4 is a partial sectional explanatory view showing another embodiment of the magnet assembly constituting the magnetic therapy apparatus according to the present invention. In the magnet structure 30, a pair of permanent magnets 34, 34 (only one permanent magnet is shown in the figure) is disposed in a magnet holder 31 made of a non-magnetic material. The basic configuration is the same as the configuration in FIG. 2. Here, a configuration in which the permanent magnet 34 is disposed so as to be movable in the axial direction of the magnet holder 31 will be mainly described.

Reference numeral 35 denotes a corrosion prevention cover made of stainless steel or the like that surrounds the columnar permanent magnet 24. A tapered portion 36 is formed on the outer peripheral surface of one end (inner end) of the corrosion prevention cover 35. A screw 37 is also provided at the center of the outer peripheral surface of the cylindrical permanent magnet support 32 of the magnet holder 31.

By adjusting the rotation amount of the magnet movement adjusting screw 38, the protrusion amount t of the permanent magnet 34 from the permanent magnet support portion 32 is adjusted, and the distance Lg between the permanent magnet magnetic poles of the adjacent magnet components is adjusted. It is possible to obtain an optimal repulsion.

Embodiment 4 FIG. 5 is a partial sectional explanatory view showing another embodiment of the magnet assembly constituting the magnetic therapy apparatus according to the present invention. The magnet structure 40 has a permanent magnet 44 arranged in a magnet holder 41 made of a non-magnetic material. This configuration is similar to the first, second, and third embodiments.
Unlike the configuration shown in FIG. 3, a main feature is that a single columnar permanent magnet 44 is used without using a pair of permanent magnets. However, this one columnar permanent magnet 44 may be configured integrally with a plurality of permanent magnets as shown in the figure. Reference numeral 45 denotes a corrosion prevention cover made of stainless steel or the like that surrounds the columnar permanent magnet 44. A screw portion 46 is formed at the center of the outer peripheral surface of the corrosion prevention cover 45, and is screwed with a screw portion 47 at the center of the inner peripheral surface of the cylindrical permanent magnet support portion 42 of the magnet holder 41.

By adjusting the amount of rotation of the magnet, the protrusion amounts t ₁ and t ₂ of the permanent magnet 44 from the permanent magnet support portion 42 are adjusted, and the distance Lg between the permanent magnet magnetic poles of adjacent magnet structures is adjusted. And an optimal repulsion can be obtained. After completing such an adjustment, an optimal position of the permanent magnet 44 is secured by a set screw 48 disposed at the center of the permanent magnet support 42. In addition, when safety is ensured only by fixing with the cap screw 48, it is not always necessary to dispose the magnet protrusion preventing caps (see FIGS. 2, 3, and 4) as shown in the first, second, and third embodiments. Absent.

In this configuration, both the screw portion 46 formed on the outer circumferential surface of the corrosion prevention cover 45 and the screw portion 47 formed on the inner circumferential surface of the permanent magnet support portion 42 have an outer circumferential surface and an inner circumferential surface other than those illustrated. The same effect can be obtained even if the threaded portions 46 and 47 are formed at predetermined positions on the surface or over the entire surface. This configuration does not use a pair of permanent magnets unlike the configurations of the _first , _second, and _third embodiments, and thus independently adjusts the protrusion amounts t ₁ , t ₂ of the permanent magnets 44 from the permanent magnet support portion 42. Although it is difficult to perform this operation, the structure is simple and the permanent magnet can be easily moved. Can be used more effectively.

Embodiment 5 FIGS. 6A and 6B are partial cross-sectional explanatory views showing another embodiment of the magnet structure constituting the magnetic therapy apparatus according to the present invention. The magnet structure 50 has a pair of permanent magnets (not shown) arranged in a magnet holder 51 made of a non-magnetic material.
This configuration is different from the configurations shown in the first, second and third embodiments.
The main feature is that the magnet structure 50 is attached to the vertebral body using not only the screw 53 but also a flange 54 fixed to a required position (four places in the figure) on the outer peripheral surface of the permanent magnet support 52. That is, when the screw 53 alone is fixed, the adjacent magnet members are in a state of repulsion with respect to each other. Therefore, there is a risk that each magnet member rotates around the screw 53, especially in a portion where the repulsive force is strong. In order to maintain the desired repulsion, it is desired to provide a rotation stop on the magnet structure.

In this configuration, after the magnet structure 50 has been attached to the vertebral body 56 via the screw 53 in advance, the auxiliary screw 55 is fixed to the flange 54 so as to stop the rotation of the magnet structure 50. It is desirable that the position of the permanent magnet be adjusted after the flange 54 is fixed .

Embodiment 6 FIGS. 7 and 8 are views for explaining a positioning jig for properly arranging a magnetic therapy device according to the present invention. FIG. 7 is a perspective explanatory view schematically showing the arrangement of the positioning jig (FIG. FIG. 7 is an explanatory partial cross-sectional view (FIG. 8) showing an arrangement relationship between a positioning jig and a magnet structure. As shown in FIG. 7, before arranging the magnet structure of the present invention, a long plate-shaped positioning jig is fixed to a required portion of the spine in advance. As the fixing means, known fixing means such as directly fixing to the vertebral body 5 with a small diameter screw (not shown) can be employed. Positioning jig 6
At 0, elongated through holes 61 are formed at a predetermined pitch. The plurality of through-holes 61 have their centers in the long direction aligned with each other. Further, cutouts 62, 62 and 63, 63 are formed at the center side end of the through hole 61 and the center side end between the adjacent through holes 61, respectively.

The positioning jig 60 having such a shape is used.
When the magnet structure shown in each of the above embodiments is arranged in the through hole 61, the outer peripheral portion of the permanent magnet support portion 72 of the magnet holder is corrected by the through hole 61 as shown in FIG. It becomes possible to arrange a plurality of magnet structures at the same pitch in the axial direction and at a predetermined pitch. A plurality of magnet components are arranged with the positioning jig 60 fixed to the vertebral body 5. After completing the positioning, the notches 62, 62 and 63, 63 are cut to disassemble the positioning jig 60. It can be removed and only the magnet structure can be used, thereby preventing the positioning jig 60 from losing spinal mobility. Also, this positioning jig 6
Reference numeral 0 denotes not only a configuration in which a plurality of through-holes 61 are independently provided as shown in the figure, but also a single through-hole communicating these through-holes 61. Although these positioning jigs are not always necessary, they are effective for quickly and appropriately administering treatment.

Example 7 In order to confirm the effect of the present invention, a study was conducted in advance using rats. Male Wistar rats (7-8 weeks old: 20
0g) The maximum energy product (BH) on the right side of the lumbar vertebra after forming 10 convex lumbar scoliosis with an average of 20 ° in advance.

The column-shaped Fe—BR system magnets are arranged such that the distance between their magnetic poles is 1 m.
m. In addition, it can be estimated that a correction force of about 200 g was acting on the rat. Two weeks after the above operation, the lumbar spine was almost normal,
It was confirmed that a correction of about 20 ° was possible.

Example 8 Based on the test results of Example 7, application to the human body was further studied. In a conventional method of correcting scoliosis mechanically, it is necessary to stretch the human body having scoliosis of about 60 ° to 70 ° with a force of about 20 to 40 kg at the time of surgery to correct the body. Later, it was confirmed that the stress was relaxed and a force of about 10 to 20 kg was required during standing and walking. Therefore, it is presumed that at least about 10 to 20 kg of repulsive force is required between the magnet components in order to obtain the same effects using the therapeutic device of the present invention.

The present inventor conducted an experiment of repulsion based on computer simulation in order to examine the specifications of the magnetic therapy apparatus of the present invention necessary for correcting scoliosis of about 60 °. When the magnet structure 10 having the configuration shown in the first embodiment is used, the maximum energy product (BH) max is 35 MGOe in the magnet holder 11 and the diameter is 15 mm to 25 mm.
mm × 15 mm to 30 mm long pair of columnar Fe-B
By disposing the R-system magnets 14 and adjusting the distance between the magnetic poles of the adjacent magnet members to about 1 mm to 10 mm, it is possible to obtain the magnetic repulsion required for correction. confirmed.

[0039]

As described above, the magnetic treatment apparatus for treating scoliosis according to the present invention utilizes the repulsive force of a plurality of magnet members arranged on each of the vertebral bodies constituting the spinal column to provide a spinal column. In order to gradually expand the curved part of the spine and enable correction of spinal deformity, the motility of the spine is not lost even during treatment, compared to a treatment device that fixes a metal rod to the conventionally known spine,
It is possible to reduce the physical and mental burden on the patient. Further, by disposing the permanent magnets constituting the magnet structure so as to be movable in the axial direction of the magnet holder, it is possible to easily adjust the repulsive force of each other even after the magnet structure is once arranged on the vertebral body. This makes it possible to quickly and safely set the optimum force required for correcting spinal deformity even during surgery.
