Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transcranial magnetic stimulation, and in particular to a multi-target transcranial magnetic stimulation neural regulation system and its application in the treatment of neurodegenerative diseases. Background Art
[0002] Neurological diseases are disorders involving structural or functional abnormalities of the central and peripheral nervous systems, including neurodegenerative diseases, mental disorders, cerebrovascular diseases, neurodevelopmental disorders, cognitive impairment, and movement disorders. These diseases often have complex etiologies and diverse pathological mechanisms. Traditional drug treatments have limited efficacy and are often accompanied by adverse reactions, necessitating an urgent need for new and effective treatments.
[0003] Transcranial magnetic stimulation (TMS) is a non-invasive neuromodulation technique based on Faraday's law of electromagnetic induction. It generates a rapidly changing, strong, focal magnetic field outside the scalp, inducing electrical currents in cerebral cortical neurons. This, in turn, causes changes in the membrane potential of the cell bodies or axon terminals, thereby regulating neuronal excitability and information transmission within the neuronal network. TMS was first used for cerebral cortical stimulation in humans in 1985 and has since undergone numerous technological iterations. Repetitive transcranial magnetic stimulation (rTMS), a key variant of TMS, was introduced into clinical practice in 1989. Its characteristic is the repeated application of magnetic stimulation at a specific frequency, resulting in different neuromodulatory effects depending on the stimulation frequency: low-frequency rTMS (≤1Hz) typically produces inhibitory effects, while high-frequency rTMS (>1Hz) produces excitatory effects.
[0004] In recent years, TMS has been widely used in the diagnosis and treatment of a variety of neurological diseases, including neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis; mental disorders such as depression, anxiety, and obsessive-compulsive disorder; stroke and its sequelae; pain-related diseases such as chronic pain, fibromyalgia, neuropathic pain, and migraine; and other neurological dysfunctions such as epilepsy, multiple sclerosis, vertigo, tinnitus, and attention deficit hyperactivity disorder.
[0005] TMS has multiple mechanisms of action at the cellular and molecular levels, including promoting synaptic plasticity, regulating neurotransmitter balance, promoting the expression of neurotrophic factors, modulating neuroinflammatory responses, improving cerebral blood flow and metabolism, reducing pathological protein deposition, and regulating neural network connectivity. These mechanisms enable TMS to be widely used in the treatment of various neurological diseases. Through stimulation of varying frequencies and patterns, it can specifically regulate abnormal neural activity and improve corresponding clinical symptoms.
[0006] However, existing transcranial magnetic stimulation technology still has certain limitations, which are mainly reflected in two aspects: First, traditional TMS usually adopts a single target stimulation mode, in which the physician manually places the stimulation coil at a specific location on the patient's scalp to perform a single type of stimulation. This method makes it difficult to fully activate and regulate the complex neural networks composed of multiple functionally related brain regions in the nervous system, resulting in poor neuromodulation effects. In particular, for functions that involve the collaborative work of multiple brain regions, such as motor coordination, if the key nodes in the relevant neural circuits cannot be activated simultaneously or sequentially, patients will face significant challenges in recovering their motor control and coordination abilities. Secondly, single-target stimulation strategies often require extended treatment cycles to achieve ideal results. Patients usually need to undergo continuous treatment for several months or even longer before observing significant symptom improvement. This not only increases the psychological burden on patients and makes compliance difficult, but may also lead to a decrease in confidence in treatment. At the same time, long-term repeated visits to the doctor also have a significant impact on patients' daily life, work, and social activities.
[0007] Therefore, there is a need in the art for a TMS neuromodulatory device capable of implementing multi-target stimulation to overcome the application limitations of existing devices. Summary of the Invention
[0008] The present invention provides a multi-target transcranial magnetic stimulation neuroregulatory system and its application in the treatment of neurodegenerative diseases, in order to solve the defects of existing transcranial magnetic stimulation methods that cannot fully activate the motor circuits of brain areas, have a long treatment cycle, and result in poor treatment effects. The multi-target transcranial magnetic stimulation neuroregulatory system of the present invention can, on the one hand, assist physicians in accurately locating the patient's brain area and adopt a multi-target collaborative stimulation strategy. It can also activate multiple functionally related brain areas simultaneously or in a specific time sequence, effectively mobilizing the overall functional network of the nervous system, thereby significantly improving treatment efficiency and clinical efficacy. This system is particularly suitable for complex neurological dysfunctions that require the collaborative participation of multiple brain areas, such as motor coordination disorders, cognitive dysfunction, and neuropsychiatric diseases.
[0009] The present invention provides a multi-target transcranial magnetic stimulation device, comprising a treatment helmet, a ring-shaped telescopic positioning component, a first TMS stimulation paddle, and a second TMS stimulation paddle. The ring-shaped telescopic positioning component is arranged on the treatment helmet and can move up and down along the longitudinal direction of the treatment helmet. The first TMS stimulation paddle and the second TMS stimulation paddle can be detachably connected to the ring-shaped telescopic positioning component respectively.
[0010] In the present invention, TMS stimulation can use various types of TMS coils to meet the needs of stimulating brain regions with different depths and precisions. The TMS coils include but are not limited to: Round coil: The earliest type of TMS coil developed, it produces a wider magnetic field distribution, with a large stimulation range but lower precision. It is suitable for motor threshold measurement and large-scale cortical stimulation, with a stimulation depth of about 1-2 cm.
[0011] Figure-of-8 / Butterfly coil: It consists of two adjacent circular coils, which produce maximum magnetic field strength at the intersection, providing more focused stimulation. It is the most commonly used standard coil and is suitable for precise targeting of cortical areas such as the motor cortex and dorsolateral prefrontal cortex, with a stimulation depth of approximately 2-3 cm.
[0012] Double cone coil: Two circular coils intersecting at a large angle produce a stronger and deeper magnetic field distribution, which is particularly suitable for stimulating deep midline structures such as the motor area lower limb representation area and the supplementary motor area, with a stimulation depth of up to 3-4 cm.
[0013] H-coil: A series of coils specially designed for deep TMS that can stimulate deeper brain structures without increasing the intensity of surface stimulation. It is suitable for stimulating deep structures such as the limbic system and basal ganglia, with a stimulation depth of up to 5-7 cm.
[0014] Cone coil: A specially designed coil with a conical magnetic field distribution, which can achieve more precise directional stimulation of deep brain areas. It is suitable for targeted regulation of structures such as the cerebellum and anterior cingulate cortex, with a stimulation depth of approximately 3-5 cm.
[0015] D-shaped coil: A coil shaped like the letter D, designed for stimulating specific anatomical structures, such as specific areas of the temporal or parietal lobes, providing focusing performance between that of a circular and figure-of-eight coil.
[0016] Cooled coil systems: Coils equipped with liquid cooling systems, such as the Cool-B and Cool-D models, can maintain stable performance during prolonged high-intensity stimulation and are suitable for high-intensity protocols such as theta burst stimulation.
[0017] Mini-coils: Small, lightweight coils suitable for precise stimulation of children or specific anatomical areas, as well as for scenarios where other neuroimaging studies need to be performed simultaneously.
[0018] Cloverleaf coil: Consists of three intersecting coils that produce a highly focused magnetic field, suitable for stimulating brain areas that require ultra-precise targeting.
[0019] Multi-ring coil: Consists of multiple concentric ring coils. The current ratio of each ring can be adjusted to optimize stimulation depth and focus, making it suitable for personalized and precise stimulation plans.
[0020] Preferably, the first TMS stimulation pulse and the second TMS stimulation pulse are different types of coils. This allows for adaptability to various conditions and treatment needs. In a specific embodiment, the first TMS stimulation pulse and the second TMS stimulation pulse can be a combination of coils suitable for stimulating brain regions at different depths. For example, the first TMS stimulation pulse is a conical coil, and the second TMS stimulation pulse is a circular coil.
[0021] By combining these various coil types, comprehensive stimulation coverage from the superficial cortex to deep brain structures can be achieved. The most appropriate coil type and combination can be selected based on the patient's specific condition and treatment needs to achieve optimal neuromodulation. The coordinated use of different coil types can simultaneously or sequentially stimulate multiple functionally related brain regions at varying depths, effectively activating and modulating complex neural networks and significantly improving treatment efficiency and clinical efficacy.

[0030] According to the present invention, a multi-target transcranial magnetic stimulation device further includes a load-bearing rod, and the treatment helmet and the load-bearing rod are detachably connected and relatively movable.
[0031] Due to the large mass of the treatment helmet and the dual-paddles, a certain amount of pressure is exerted on the patient's head during treatment, potentially causing discomfort and leading to head movement, which in turn shifts or offsets the dual-paddles, affecting the stimulation effect. By connecting the load-bearing rods to external support components such as exoskeleton systems or other wearable devices, the pressure can be directed and distributed to the external support components, making the therapeutic effects of the transcranial magnetic stimulation device and system of the present invention more stable and effective.

DETAILED DESCRIPTION
[0060] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments, and they should not be understood as limitations on the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, it should be understood that the terms used are only for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0061] See also Figure 1 The present invention provides an embodiment of a multi-target transcranial magnetic stimulation device (this embodiment may be referred to as a "dual-beat transcranial magnetic stimulation device"), which may include: a treatment helmet 1, an annular telescopic positioning component 2, a first TMS stimulation paddle 3, a second TMS stimulation paddle 4, and a load-bearing rod 5. The annular telescopic positioning component 2 is disposed on the treatment helmet 1 and can move up and down along the longitudinal direction of the treatment helmet 1 and be positioned to assist in locating the area to be stimulated on the wearer's head. The first TMS stimulation paddle 3 and the second TMS stimulation paddle 4 can be rigidly and detachably connected to the annular telescopic positioning component via connectors such as buckles to prevent the positions of the stimulation paddles from changing during treatment. The treatment helmet 1 and the load-bearing rod 5 can be detachably connected via a spherical joint connector, and the treatment helmet 1 can move relative to the load-bearing rod 5, which not only facilitates adjustment of the position (e.g., direction) of the treatment helmet 1, but also shares the weight of the treatment helmet 1, reducing the gravity borne by the wearer's head.
[0062] Specifically, regarding the structure of the treatment helmet 1: On the one hand, the treatment helmet 1 includes a head ring 101, a curved first ruler 102 and a curved second ruler 103. The curved first ruler 102 and the curved second ruler 103 are arranged on the head ring 101 and intersect in a cross shape, and the curved first ruler 102 and the curved second ruler 103 and the head ring 101 form an internal space that can accommodate the patient's head, and the curved first ruler 102 and the curved second ruler 103 are both provided with tracks along their curved directions for the annular telescopic positioning assembly 2 to move up and down along the curved first ruler 102 and the curved second ruler 103.
[0063] The doctor can locate the area to be stimulated on the wearer's head by moving the annular telescopic positioning component 2 on the tracks on the curved first scale 102 and the curved second scale 103, and remember the position of the wearer's area to be stimulated according to the scales on the scales. This can save time in relocating the area to be stimulated during the next treatment, and can ensure the uniformity of the stimulation position for each treatment, effectively improving the treatment efficiency.
[0064] On the other hand, the treatment helmet 1 includes a first helmet fixing knob 104 and a first helmet fixing gasket 105. The first helmet fixing knob 104 is arranged at the top of the treatment helmet 1 (i.e., the intersection of the curved first scale 102 and the curved second scale 103), and the knob part of the first helmet fixing knob 104 (the knob part is for people to rotate the knob manually) is located outside the treatment helmet 1, and the free end is located inside the treatment helmet 1, and the first helmet fixing gasket 105 is arranged at the free end of the first helmet fixing knob 104. The shape of the first helmet fixing knob 104 can be similar to that of a screw.
[0065] The treatment helmet 1 also includes a second helmet fixing knob 106 and a second helmet fixing gasket 107. The second helmet fixing knob 106 is disposed on the side of the treatment helmet 1, with the knob portion of the second helmet fixing knob 106 located outside the treatment helmet 1 and the free end located inside the treatment helmet 1. The second helmet fixing gasket 107 is disposed at the free end of the second helmet fixing knob 1. Similarly, the helmet fixing assembly formed by the combination of the second helmet fixing knob 106 and the second helmet fixing gasket 107 is provided in several groups (e.g., three groups), which are respectively arranged at equal intervals in the transverse direction on the side of the treatment helmet 1. Specifically, they can be arranged at equal intervals on the head circumference ring 101. More specifically, the several groups of helmet fixing gaskets arranged on the head circumference ring 101 can form a gasket ring inside the head circumference ring 101. In addition, the first helmet fixing gasket 105 and the second helmet fixing gasket 107 are both made of flexible materials to enhance the patient's comfort when wearing the treatment helmet 1.
[0066] When the doctor puts on the treatment helmet for the wearer, he can rotate the helmet fixing knobs on various positions of the treatment helmet to make the helmet fixing gaskets on various positions counteract the wearer's head to fix the treatment helmet on the wearer's head. Because the wearer may turn his head and other movements during treatment, the position of the treatment helmet may change, which may cause the actual stimulated position to change and affect the treatment effect. This situation can be avoided by cooperating with the helmet fixing knobs and helmet fixing gaskets.
[0067] Further, regarding the annular telescopic positioning component 2: The annular telescopic positioning assembly 2 includes a first annular telescopic positioning shaft 201, a second annular telescopic positioning shaft 202, a first positioning fastener 203 and a second positioning fastener 204. The first annular telescopic positioning shaft 201 and the second annular telescopic positioning shaft 202 are arranged parallel to each other and are located in the track of the curved first scale 102 and the curved second scale 103 of the treatment helmet 1. The first positioning fastener 203 is arranged in the track of the curved second scale 103 along with the first annular telescopic positioning shaft 201, and the second positioning fastener 204 is arranged in the track of the curved second scale 103 along with the second annular telescopic positioning shaft 202, that is, the first annular telescopic positioning shaft 201 and the second annular telescopic positioning shaft 202 can both be arranged along the curved first scale 102 and the curved second scale 103. Track movement, thereby achieving up and down movement along the longitudinal direction of the treatment helmet 1, and the first positioning fastener 203 will move on the track with the first annular telescopic positioning shaft 201, and the second positioning fastener 204 will move on the track with the second annular telescopic positioning shaft 202. When the doctor uses the first annular telescopic positioning shaft 201 and the second annular telescopic positioning shaft 202 to position the stimulation area, the first positioning fastener 203 can be used to fix the first annular telescopic positioning shaft 201 on the curved second scale 103, and the second positioning fastener 204 can be used to fix the second annular telescopic positioning shaft 202 on the curved second scale 103. The first positioning fastener 203 and the second positioning fastener 204 can be knobs, and the annular telescopic positioning shafts are fixed to the scale by rotating and squeezing.
[0068] The physician can accurately locate the area to be stimulated on the wearer's head by sliding the first annular telescopic positioning axis 201 and the second annular telescopic positioning axis 202 along the tracks of the curved first scale 102 and the curved second scale 103 on the treatment helmet 1, and fixing the first annular telescopic positioning axis 201 and the second annular telescopic positioning axis 202 with the first positioning fastener 203 and the second positioning fastener 204, and then connecting the first TMS stimulation beat and the second TMS stimulation beat to the first annular telescopic positioning axis 201 and / or the second annular telescopic positioning axis 202.
[0069] The transcranial magnetic stimulation device provided by the present invention can, when in use, first fix the treatment helmet to the head of a patient with spinocerebellar ataxia by using a helmet fixing knob and a helmet fixing gasket in combination. The physician can slide the first annular telescopic positioning axis and the second annular telescopic positioning axis along the tracks of the first ruler and the second ruler on the treatment helmet according to the head shape of each patient, and use the first positioning fastener and the second positioning fastener to fix the first annular telescopic positioning axis and the second annular telescopic positioning axis, thereby accurately locating the cerebellar hemisphere and the motor cortex M1 area of the wearer's head, and recording the precise position of the area to be stimulated for the patient for the next treatment. The first TMS stimulation beat and the second TMS stimulation beat are then detachably connected to the corresponding area to be stimulated, and the first TMS stimulation beat and the second TMS stimulation beat are used to perform double-beat transcranial magnetic stimulation on the patient, which can fully activate the patient's brain area motor circuit and greatly improve the treatment efficiency and quality.
[0070] Spinocerebellar ataxia (SCA) is an autosomal dominant disorder characterized by progressive impairment of balance and coordination, often manifesting as gait ataxia, movement disorders, and dysarthria. Some subtypes exhibit phenotypic heterogeneity and may be associated with pyramidal and extrapyramidal lesions, peripheral neuropathy, and optic atrophy. Currently, there is no specific treatment for SCA, and clinical management primarily relies on symptomatic supportive care.
[0071] See also Figure 3 In this example, 3 SCA patients were collected from the neurology clinic of Peking Union Medical College Hospital between July and December 2024, and all patients signed informed consent. Figure 1 The transcranial magnetic stimulation device shown (wherein the first TMS stimulation beat is a circular coil and the second TMS stimulation beat is a conical coil) performs dual-beat stimulation. The treatment plan in this embodiment has been approved by the internal ethics review of Peking Union Medical College Hospital.
[0072] First, the patient's resting motor threshold (RMT) can be measured. Before measuring the RMT, the patient undergoes a 5T MRI scan of the head and a patient head model is imported into the software. With the patient in a seated position, the thumb motor cortex (M1) on the dominant hand (if the patient is right-handed, the left M1 area is stimulated) is stimulated using a single pulse pattern. Ten stimulations are administered, with five of these stimuli eliciting movement of the thumb abductor muscle (elicited evoked potentials exceeding 50 mV). This stimulation intensity is considered the RMT. After every ten stimulations, the RMT is re-measured.
[0073] In this embodiment, the stimulation scheme for the patient is: Location: left motor cortex M1 hand area and cerebellar vermis; Magnetic stimulation coils: a circular coil was used for the left motor cortex M1 hand area, and a conical coil was used for the cerebellar vermis; Stimulation parameters: Circular coil: Frequency: 10 Hz; Strength: 100% RMT; Sequence: 100, 10 times / sequence; Interval: 10s (10-25s).
[0074] Conical coil: Frequency: 10Hz; Strength: 120% RMT; Sequence: 20, 50 times / sequence; Interval: 25s (10-25s); Stimulation time: Stimulation is performed once in the morning and once in the afternoon every day for 10 consecutive days.
[0075] Before and after stimulation, patients were evaluated with scales, including: (1) Assessment of cognitive changes: Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA); (2) Assessment of mood changes: SAS, SDS; (3) Assessment of ataxia: Ataxia Assessment and Rating Scale (SARA), International Cooperative Ataxia Rating Scale (ICARS); (4) Assessment of sleep changes: RBDSQ; (5) Assessment of walking changes: 10m walk test, gait analysis system.
[0076] (1) Cognitive changes: MMSE and MoCA scores increased after treatment; (2) Mood changes: SAS scores showed that anxiety levels decreased after treatment, indicating that treatment may have a positive effect on alleviating anxiety. SDS scores were relatively stable with little change, indicating that depression did not improve significantly.
[0077] (3) Changes in ataxia: ICARS and SARA scores showed a decrease before and after treatment, indicating that the patients had a certain degree of improvement in ataxia.
[0078] (4) Changes in sleep: The score decreased slightly after treatment, indicating that the sleep condition has partially improved.
[0079] (5) Changes in walking condition: After treatment, the walking speed and stride length increased slightly, especially the stride length, which showed a significant improvement in walking condition.
[0080] The above results demonstrate that the multi-target transcranial magnetic stimulation device provided in this example has a positive therapeutic effect on patients, fully demonstrating the potential value of TMS in the treatment of SCA. Specifically, this example demonstrates that TMS can improve motor coordination and balance in SCA patients by modulating the function of the cerebellar-thalamic-cortical circuit. In particular, repetitive transcranial magnetic stimulation of the cerebellum and motor cortex can effectively improve patients' ataxia symptoms, gait instability, and fine motor impairments. Furthermore, TMS can comprehensively improve neurological function in SCA patients by promoting neuroplasticity, regulating neurotransmitter balance, and increasing cerebral blood flow.
[0081] The following provides a method for utilizing a multi-target transcranial magnetic stimulation device (e.g., Figure 1 The treatment plan in this embodiment has been approved by the internal ethics review of Peking Union Medical College Hospital.
[0082] Example 2: Multi-target TMS stimulation therapy was performed on patients with Alzheimer's disease using a multi-target TMS device. The treatment plan and the types of the first TMS stimulation beat and the second TMS stimulation beat used are shown in Table 1.
[0083] Table 1
[0084] The corresponding patient types for the above different schemes are shown in Table 2.
[0085] Table 2
[0086] Implementation Case 3: Utilization Figure 1 The multi-target transcranial magnetic stimulation device shown was used to perform multi-target stimulation treatment on ALS patients. The treatment plan and the types of the first TMS stimulation beat and the second stimulation beat used are shown in Table 3.
[0087] Because most ALS patients have cortical hyperexcitation, and clinically some ALS patients have also been found to have cortical excitation inhibition, RMT and MEP evoked potential tests should be performed before treatment to determine the specific treatment plan.

[0091] After the patient wears the treatment helmet, the doctor can use the annular telescopic positioning component to locate the area to be stimulated and obtain the position data of the area to be stimulated, and then input the position data of the area to be stimulated into the multi-target transcranial magnetic stimulation neuroregulation system to record the position data of the area to be stimulated of the patient for use in the next treatment. After the doctor completes the positioning of the area to be stimulated and connects the stimulation beat to the treatment helmet, he can send a stimulation instruction to the stimulation signal generating module through the control terminal. The stimulation signal generating module responds to the stimulation instruction issued by the control terminal to cause the first TMS stimulation beat and the second TMS stimulation beat located in the area to be stimulated to generate magnetic stimulation according to the stimulation scheme set in the stimulation instruction, thereby realizing multi-target transcranial magnetic stimulation neuroregulation of the patient.
