[0006] (Problems to be Solved by the Invention)

[0007] In the above-described vector potential generating device, the solenoid coil wound with a small coil diameter extends along the coil axis coiled in a spiral shape. Therefore, the length of the wire constituting the solenoid coil becomes long, and the wire itself is also a thin wire. As a result, the resistance and inductance of the solenoid coil increase. Thus, when the resistance and inductance increase, it is difficult to conduct a large current alternating current through the solenoid coil, and further, it is difficult to generate a strong vector potential.

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023]

First Embodiment

[0024] Figure 1 FIG. is a perspective view showing the structure of a vector potential generating device according to the first embodiment of the present invention. Figure 2 FIG. is showing Figure 1 a side view of the vector potential coil device 1 in Figure 1 The vector potential generating device shown in FIG. includes a vector potential coil device 1 and a power supply device 2.

[0025] As shown in Figure 1 and Figure 2As shown, the vector potential coil device 1 includes a laminated conductor component 11 having a spiral roll shape. The laminated conductor component 11 includes a first end face portion 11a which is the end face on the inner peripheral side of the roll and a second end face portion 11b which is the end face on the outer peripheral side of the roll. Here, the laminated conductor component 11 is a non-magnetic component and a component with good conductivity (for example, a copper component).

[0026] In the first embodiment, the laminated conductor component 11 has a spiral roll shape centered on a straight central axis.

[0027] In addition, the power supply device 2 generates a voltage of a specific waveform, which causes a current of a specific waveform that changes with time (alternating current such as sine wave, triangular wave, rectangular wave, pulse current, current obtained by combining these, etc.) to flow through the laminated conductor component 11 via the first end face portion 11a and the second end face portion 11b. For example, the power supply device 2 is a high-frequency power supply of about 1 kHz to 1 GHz. In addition, for example, the power supply device 2 can continuously cause an alternating current of a specified frequency to flow through the laminated conductor component 11, or can intermittently or in a specified time series pattern, cause an alternating current of a specified frequency to flow through the laminated conductor component 11 at specified time intervals.

[0028] Figure 3 is Figure 1 the developed view of the laminated conductor component 11 in. As Figure 3 shown, in the first embodiment, the laminated conductor component 11 is a substantially rectangular plate-shaped component.

[0029] Furthermore, as Figures 1 to 3 shown, the vector potential coil device 1 further includes a core conductor component 12 which is (electrically and mechanically) connected to the first end face portion 11a along the first end face portion 11a. The core conductor component 12 is a rod-shaped component which, for example, has a diameter larger than the thickness of the laminated conductor component 11. In addition, the power supply device 2 is electrically connected to the core conductor component 12, so that the current I(t) of the specific waveform that changes with time flows through the laminated conductor component 11 via the core conductor component 12, the first end face portion 11a, and the second end face portion 11b.

[0030] Specifically, here, as Figure 3As shown, one end of the output terminal of the power supply device 2 is electrically connected to one end portion 12t of the core conductor member 12; on the end portion 11t1 on the side of the other end portion of the core conductor member 12 at both ends of the first end face portion 11a, an electrical connection point between the core conductor member 12 and the laminated conductor member 11 is provided; the other end of the output terminal of the power supply device 2 is electrically connected to the end portion 11t2 of the second end face portion 11b of the laminated conductor member 11 that is diagonal to the end portion 11t1. It should be noted that except for the end portion 11t1, the core conductor member 12 and the laminated conductor member 11 are not electrically connected. By doing so, in the laminated conductor member 11, the current I(t) conducts between the end portion 11t1 and the end portion 11t2.

[0031] The above-mentioned current I(t) conducts in a manner of spirally coiling around the (spiral-shaped) central axis. Therefore, when the current I(t) is an alternating current, an alternating magnetic field is generated in the direction of the central axis, thereby generating an alternating vector potential A that coils around the central axis.

[0032] In the first embodiment, the core conductor member 12 is made of a soft magnetic material such as permalloy and has soft magnetism. By doing so, the above-mentioned alternating magnetic field is enhanced, and further, the vector potential A is also enhanced.

[0033] Next, the operation of the above-mentioned vector potential generating device will be described.

[0034] The power supply device 2 applies an alternating voltage of a specified frequency to the end portion 12t of the core conductor member 12 and the second end face portion 11b of the laminated conductor member 11, so that the current I(t) conducts in the laminated conductor member 11 via the core conductor member 12, the first end face portion 11a (end portion 11t1), and the second end face portion 11b (end portion 11t2).

[0035] In the laminated conductor member 11, the current I(t) conducts between the first end face portion 11a and the second end face portion 11b in a manner of spirally coiling. By doing so, when the current I(t) is an alternating current, an alternating magnetic field along the (spiral-shaped) central axis (core conductor member 12) is generated, and an alternating vector potential A that coils around the central axis is generated.

[0036] At this time, the greater the axial length of the laminated conductor member 11, the greater the width in the direction substantially perpendicular to the conduction direction of the current I(t), and the smaller the resistance value between the first end face portion 11a and the second end face portion 11b. Therefore, a large current can be conducted in the laminated conductor member 11, and further, a large vector potential A can be generated.

[0037] As described above, according to the first embodiment, the vector potential coil device 1 includes: a spiral-wound layered conductor member 11, a first end face portion 11a on the inner peripheral side of the winding of the layered conductor member 11, and a second end face portion 11b on the outer peripheral side of the winding of the layered conductor member; the power supply device 2 causes a current I(t) to flow through the first end face portion 11a and the second end face portion 11b in the layered conductor member 11, so that a vector potential is generated by the layered conductor member 11.

[0038] By doing so, a large current can flow through the vector potential coil device 1, and thus a vector potential generating device with high output can be obtained. Therefore, for example, it can be expected to be applied to uses such as treating brain diseases such as epilepsy by applying a strong vector potential to the head.

[0039] In addition, as described above, by providing the soft magnetic core conductor member 12, the stray capacitance becomes relatively small, and thus the characteristics of the vector potential coil device 1 in the high-frequency range become good.

[0040] Furthermore, for example, the layered conductor member 11 is formed by winding a plate-shaped metal member into a spiral-wound shape, and thus the vector potential coil device 1 can be manufactured relatively easily.

[0041]

Second Embodiment

[0042] Figure 4 It is a developed view of the layered conductor member 11 of the vector potential coil device 1 showing the second embodiment.

[0043] In the second embodiment, for example, as Figure 4 shown, the layered conductor member 11 is a mesh member. For example, the layered conductor member 11 is a member formed by connecting a plurality of copper wires to each other in a mesh shape. It should be noted that the mesh shape (mesh pattern) of the layered conductor member 11 is not limited to Figure 4 the shape. In addition, the mesh member used for the layered conductor member 11 may also be a plate-shaped member provided with a plurality of holes such as a perforated metal plate.

[0044] Figure 5 It is a diagram showing Figure 4 the equivalent circuit of the vector potential coil device 1 shown. As Figure 5 shown, the vector potential coil device 1 seen from the power supply device 2 can be regarded as a circuit of a resistor R, an inductor L, and a stray capacitance C. The resistor R is the resistance between the first end face portion 11a and the second end face portion 11b. The inductor L is the inductance between the first end face portion 11a and the second end face portion 11b.

[0045] Here, compared with the vector potential coil device in which a solenoid coil wound with a small coil diameter extends along the coil axis coiled in a scroll shape, in the vector potential coil device 1 of the second embodiment, the axial length of the laminated conductor member 11 is large, the width in a direction substantially perpendicular to the current conduction direction is large, and the number of turns is relatively small. Therefore, the resistance R and the inductance L become smaller. In addition, since the laminated conductor member 11 is a mesh member, the facing area between the layers of the laminated conductor member 11 is small, and thus the stray resistance C also becomes smaller. As a result, conduction of a large current can be achieved.

[0046] Furthermore, in the vector potential coil device 1 of the second embodiment, since the laminated conductor member 11 is a mesh member, the conductor surface area is large. Therefore, even for high-frequency alternating current, the influence of the skin effect is small. In addition, since the laminated conductor member 11 has good heat dissipation characteristics, a large current can be conducted.

[0047] It should be noted that since the other structures and operations of the vector potential generating device of the second embodiment are the same as those of the first embodiment, the description thereof is omitted.

[0048]

Third Embodiment

[0049] Figure 6 FIG. is a perspective view showing the structure of the vector potential generating device according to the third embodiment of the present invention.

[0050] In the third embodiment, for example, as Figure 6 shown, the laminated conductor member 11 has a spiral winding shape centered on a curved central axis.

[0051] Here, for example, as Figure 6 shown, the laminated conductor member 11 has a spiral winding shape centered on an annular central axis. The laminated conductor member 11 has a substantially toroidal outer shape, and generates a vector potential A in a manner that links with the substantially toroidal shape.

[0052] In addition, in Figure 6 , the laminated conductor member 11 has a substantially toroidal outer shape, but may also have a shape such as a spiral winding shape centered on an arcuate central axis after being cut, for example, in half (two halves) in the circumferential direction of the substantially toroidal outer shape.

[0053] In addition, regarding the laminated conductor member 11 in the third embodiment, it may be a plate-like member (without holes) as in the first embodiment, or a mesh member as in the second embodiment.

[0054] It should be noted that since the other structures and operations of the vector potential generating device of the third embodiment are the same as those of the first or second embodiment, their descriptions are omitted.

[0055]

Fourth Embodiment

[0056] The treatment device according to the fourth embodiment of the present invention includes the vector potential generating device of any one of the above first to third embodiments, and this treatment device applies the vector potential generated by this vector potential generating device to a specific part of a living body (human body, animal, etc.).

[0057] Figure 7 It represents Figure 6 a diagram showing a configuration example of the vector potential generating device shown. For example, in the case of a treatment device for treating brain diseases such as epilepsy, brain tumors, and Parkinson's disease, for example, as Figure 7 shown, the vector potential generating device of the third embodiment is arranged close to the head, and the vector potential A is applied in such a way as to generate a strong electric field in the normal direction of the body surface.

[0058] In the case of a treatment device for brain diseases, this treatment device may also be configured to include a controller that controls the power supply device 2, and this controller is controlled to (obtain from a medical device connected to the human body) the brain wave or electrocardiogram of the human body as an object and monitor it, and according to this brain wave or electrocardiogram, at a specific time, the power supply device 2 causes the above current to flow through the vector potential coil device 1. In addition, in this case, the controller may also be controlled to cause the above current to flow through the vector potential coil device 1 by the power supply device 2 in a specific pulse sequence (pulse sequence) that is effective for treatment.

[0059] In addition, for example, it may also be configured that the vector potential generating device further includes a support body having a shape that conforms to the shape of the human head, and the above vector potential coil device 1 is fixed to this support body. As this support body, a safety helmet worn on the head, a bracket for arranging the vector potential coil device 1 near the head, etc. are used. Or, the above support body may also be a device that contacts the head, such as a pillow or a headrest of a chair. In this case, the above vector potential coil device 1 is built into such a support body.

[0060] Using such a support, the vector potential coil device 1 is arranged close to the position where the vector potential is generated in the human brain. That is, by passing an alternating current through the vector potential coil device 1, an alternating vector potential is generated in the brain inside the head. By doing so, an alternating electric field or an alternating current is applied to the brain. For example, as disclosed in International Publication Gazette WO2017 / 072706, by applying an alternating electric field to treat brain tumors, the power supply device 2 sets the conditions (frequency, etc.) required for brain tumor treatment, and the vector potential coil device 1 non-invasively applies an alternating electric field of such conditions to the brain. For example, in order to apply an alternating electric field as disclosed in International Publication Gazette WO2017 / 072706, usually, after shaving the hair, electrode patches are attached to the head skin, but according to the treatment device of the present embodiment, hair shaving is not required, and it is also not necessary to attach adhesive electrode patches to the head skin, thereby reducing the burden (physical and mental burdens) on the patient during treatment by applying an alternating electric field.

[0061] In addition, the treatment device of the fourth embodiment can also be applied to the diseases shown below.

In addition, it can be used to remove bone blocks in the pathological conditions of neoplastic bone formation or bone tumors, including osteosarcoma, chondrosarcoma, Ewing's sarcoma, osteoblastoma, osteoid osteoma, etc. Similarly, it can be used to remove bone spurs formed in the legs, shoulders, necks, spines, etc. due to chronic osteoarthritis deformans, rheumatoid arthritis, reactive arthritis, rotator cuff injury, plantar fasciitis, spondylosis, and / or spinal stenosis.

[0081] It should be noted that for the above-mentioned embodiments, various changes and modifications can also be made without departing from their gist and scope and without weakening the intended advantages. Since these changes and modifications are obvious to those skilled in the art, these changes and modifications should also be included in the protection scope of the claims of this application.

[0082] For example, in any one of the above-mentioned first to third embodiments, the core conductor member 12 may not be provided, but the power supply device 2 may be electrically connected to the above-mentioned ends 11t1 and 11t2 to conduct the current I(t).

In addition, the electrically connected portion of the power supply device 2 in the laminated conductor member 11 and / or the core conductor member 12 may also be plural (for example, both ends). In this case, the power supply device 2 is connected to each connection portion through, for example, a plurality of wiring lines.
