Description

Multi-axis transcranial magnetic stimulation (TMS) positioning device and magnetic stimulation system including the same

[0001] The present invention relates to the field of transcranial magnetic stimulation (TMS) technology, and more specifically to a multi-axis TMS positioning device that supports more accurate and consistent positioning of TMS coils, and a magnetic stimulation system including the same.

[0002] Transcranial magnetic stimulation (hereinafter referred to as 'TMS') is a brain stimulation technique that activates or inhibits nerve cells in specific areas of the brain using local magnetic field waves induced on the surface of the head outside the body. The principle of TMS is to generate a magnetic field of strength of several Tesla by applying a strong electric current to an electromagnetic coil. It is a method of stimulating the brain by transmitting the fluctuating energy of these magnetic field waves to the brain, thereby inducing depolarization in nerve cells within a range of several centimeters below the coil.

[0003] TMS is a representative non-invasive brain stimulation technique, and its therapeutic applications are being actively researched for conditions such as depression, insomnia, obsessive-compulsive disorder, movement disorders, dementia, and brain dysfunction that do not respond well to drug therapy or psychotherapy. Typically, the recommended treatment time for TMS is about 20 minutes, once a day, five days a week, requiring high-frequency treatment. For example, when magnetic stimulation therapy of about 20 to 50 minutes per day is repeatedly applied over several days to central nervous system diseases such as stroke or spinal cord injury, effects of neuroplasticity, neuroregeneration, and functional recovery have been reported.

[0004] In existing TMS treatment protocols, medical staff place coils on the patient's head and manually set the cranial surface location corresponding to the specific target brain region by referring to approximate external markers or cranial structures. However, this conventional method has several limitations.

[0005] First is the issue of coil position reproducibility. It is not easy to reposition the coil to the exact same position and angle in every session, which negatively impacts the consistency and reliability of treatment outcomes. Particularly when performing long-term repeated treatments or treating diverse patient groups, the reduction in efficacy caused by coil position errors can accumulate.

[0006] Second, there is a high dependence on specialized medical personnel. Current TMS protocols require the intervention of skilled medical staff during the coil positioning process, which leads to increased labor costs, time consumption, and limited accessibility. The burden of equipment and treatment costs serves as a factor hindering patient treatment opportunities and the expansion of services by medical institutions.

[0007] Third, it is difficult to respond to the diversifying indications and the need for personalized treatment. As the number of diseases and symptoms subject to TMS increases, the optimal stimulation sites differ for each condition, and customized stimulation strategies are required that reflect the individual wearer's skull structure or neurophysiological characteristics. However, it is difficult to implement this simply and economically with existing equipment or methods.

[0008] Technological development is required to overcome these limitations and improve the efficiency and accuracy of TMS treatment and research.

[0009] To overcome these limitations and improve the efficiency and accuracy of transcranial magnetic stimulation (TMS) treatment and research, we propose a positioning mechanism capable of multi-axial position adjustment.

[0010] The present invention aims to provide a new technology that resolves the inaccuracy and inefficiency of coil positioning that occur during the operation of existing transcranial magnetic stimulation devices, and facilitates the setting of various customized stimulation sites required for the treatment of various neuropsychiatric disorders and neuroscience research.

[0011] The present invention aims to ensure consistency and reliability of treatment effects by introducing a positioning mechanism capable of precisely adjusting coil positions in multiple axes, thereby reproducing the same stimulation position and angle for every treatment session.

[0012] The present invention aims to present a device capable of flexibly responding to the head shape of each wearer and target areas for each disease through a semi-customized mounting structure combining standardized modules.

[0013] The present invention aims to provide a device capable of performing accurate coil positioning without the continuous involvement of skilled medical personnel through a guide marker and a simplified mechanism.

[0014] The present invention aims to present a TMS system that enables easy TMS treatment to be performed in a home environment, beyond medical institutions, by simplifying device operation.

[0015] The multi-axis TMS positioning device of the present invention for achieving the above-mentioned purpose comprises: a band portion formed to be in close contact along the circumference of the wearer's head; a main frame formed to be connected in a vertical direction to the band portion and extending in a curved shape from the occipital side of the wearer to the vicinity of the frontal lobe; and a connecting portion configured such that one side is connected to the main frame and is movable along the longitudinal direction of the main frame, and the other side can be coupled to an applicator including a magnetic generating coil.

[0016] In addition, the multi-axis TMS positioning device of the present invention further includes a first adjustment unit formed in the portion connecting the band portion and the main frame; and the first adjustment unit may be configured such that the main frame can move up and down and rotate left and right at the portion connecting it to the band portion.

[0017] In addition, the multi-axis TMS positioning device of the present invention further includes a second adjustment unit formed in a portion connecting the main frame and the connecting portion; and the second adjustment unit may be configured such that the applicator coupled to the connecting portion can perform multi-degree-of-freedom rotation or multi-axis rotation with respect to the main frame or the connecting portion.

[0018] In addition, the multi-axis TMS positioning device of the present invention may be configured such that the main frame includes a rail arranged along the longitudinal direction of the main frame, and the connecting part moves along the rail.

[0019] In addition, the multi-axis TMS positioning device of the present invention may include an elastic material or a length adjustment means for the band portion so that it can be adjusted to fit the wearer's head circumference.

[0020] In addition, the multi-axis TMS positioning device of the present invention may include a band portion that includes a guide member formed to align the position of the device based on the wearer's nose, ear, or a specific body part.

[0021] In addition, the multi-axis TMS positioning device of the present invention may be configured such that the first adjustment unit includes a button, the main frame moves relative to the band unit when the button is compressed or released, and the main frame is fixed relative to the band unit when the button is compressed or released in the opposite direction.

[0022] In addition, the multi-axis TMS positioning device of the present invention may have the connecting part and the second adjusting part formed integrally, and the second adjusting part may include a ball hinge formed on one side of the connecting part and a stopper formed to surround the ball hinge to restrict the movement of the ball hinge.

[0023] In addition, the multi-axis TMS positioning device of the present invention may include, in the connecting portion, a fine adjustment member for adjusting the gap between the main frame and the applicator on the one side or the other side.

[0024] In addition, the magnetic stimulation system of the present invention includes the multi-axis TMS positioning device described above, an applicator coupled to the connection part of the multi-axis TMS positioning device and comprising a magnetic generating coil that generates a magnetic field; and a main body that provides a magnetic stimulation signal to the applicator.

[0025] In addition, the magnetic stimulation system of the present invention may have the magnetic generating coil being a figure-eight coil, and the figure-eight coil may be formed so that the spacing between the coils is adjustable.

[0026] In addition, the magnetic stimulation system of the present invention may include a hinge structure adjustable so that the central portion of the applicator is bent at a specific angle.

[0027] In addition, the magnetic stimulation system of the present invention may be formed such that one side of the main frame is connected to the band portion through the first adjustment portion, and the other side of the main frame is not connected to the band portion and is open.

[0028] As described above, the multi-axis TMS positioning device according to the present invention provides a positioning device capable of precisely adjusting the coil position and angle in multiple directions (front-back, left-right, up-down, and rotational axis). This allows the same stimulation position to be consistently reproduced for every treatment session, thereby improving the stability and reliability of the treatment effect.

[0029] The multi-axis TMS positioning device and the magnetic stimulation system including the same according to the present invention introduce a modular structure and combine various standard components to flexibly select stimulation points according to the wearer's head shape, target brain region, and disease characteristics. This facilitates the implementation of customized TMS stimulation based on specific characteristics for each disease and wearer, and allows for the expectation of optimizing treatment results.

[0030] The multi-axis TMS positioning device according to the present invention enables accurate coil positioning without the need for specialized medical personnel through guide markers and a simple mechanism. This leads to a reduction in human resources and time costs, thereby lowering overall TMS treatment costs and increasing the operational efficiency of medical institutions.

[0031] The multi-axis TMS positioning device and the magnetic stimulation system including the same according to the present invention can achieve the target therapeutic effect with fewer sessions or shortened treatment time through optimized coil positioning and stimulation settings tailored to the individual characteristics of the wearer. This can increase the wearer's treatment compliance and ultimately improve the overall efficiency and effectiveness of TMS treatment.

[0032] The multi-axis TMS positioning device and the magnetic stimulation system including the same according to the present invention can greatly improve accessibility to TMS treatment by simplifying the operation method of the device, thereby enabling easy TMS treatment to be performed even in a home environment outside of a medical institution.

Therefore, such definitions must be based on the content throughout this specification.

[0055] Hereinafter, a multi-axis transcranial magnetic stimulation (hereinafter, TMS) positioning device (100) and a magnetic stimulation system (1000) including the same according to the present disclosure will be described with reference to FIGS. 1 to 10.

[0056] FIG. 1 is a block diagram schematically illustrating each configuration of a magnetic stimulation system (1000) according to one embodiment of the present invention.

[0057] The magnetic stimulation system (1000) of the present invention is an integrated system for applying transcranial magnetic stimulation (TMS), and aims to precisely deliver magnetic stimulation to a suitable location on the wearer's head and maximize treatment efficiency and safety.

[0058] The magnetic stimulation system (1000) of the present invention can be applied to various fields such as the treatment of mental illness, neuroscience research, chronic pain management, and rehabilitation therapy. The magnetic stimulation system (1000) of the present invention is utilized in the treatment of neuropsychiatric disorders such as depression, obsessive-compulsive disorder, and PTSD, and can be usefully employed in rehabilitation therapy to support the functional recovery of wearers with nerve damage, as well as in the treatment of chronic pain and migraines. Furthermore, the magnetic stimulation system (1000) of the present invention can also contribute to neuroscience research for the functional study of specific brain regions and the evaluation of stimulation effects.

[0059] Referring to FIG. 1, the magnetic stimulation system (1000) of the present invention comprises a multi-axis TMS positioning device (100), an applicator (200), and a main body (300). The magnetic stimulation system (1000) of the present invention enables optimized position adjustment of the applicator (200) through the multi-axis TMS positioning device (100) and can provide a high-precision stimulation signal.

[0060] The multi-axis TMS positioning device (100) of the present invention is a device that is mounted on the wearer's head and performs the function of precisely adjusting and fixing the position of the applicator (200). The multi-axis TMS positioning device (100) is designed to be adjustable in multiple axial directions to suit the wearer's head shape and the stimulation area, thereby ensuring consistency and effectiveness of treatment. The multi-axis TMS positioning device (100) is designed to respond to various indications by stably maintaining the position of the applicator (200) while allowing the position to be adjusted as needed.

[0061] The multi-axis TMS positioning device (100) of the present invention will be described in detail below with reference to FIGS. 2 to 9.

[0062] The applicator (200) is a device that physically transmits magnetic stimulation signals to the wearer's brain and is connected to the main body (300) to generate a magnetic field by means of magnetic stimulation signals generated from the main body (300). The applicator (200) includes a magnetic generating coil that generates a magnetic field. The applicator (200) may include various types of coils that perform transcranial magnetic stimulation.

[0063] The applicator (200) is coupled to the multi-axis TMS positioning device (100) of the present invention and can move to a precise position.

[0064] As an example, the central portion of the applicator (200) may include a hinge structure that can be bent at a specific angle, as shown in FIGS. 2 to 4. In this case, the magnetic generating coil included in the applicator (200) is preferably a figure-eight coil, and when the center of the applicator (200) includes a hinge structure to be bent, the figure-eight coil included in the applicator (200) is preferably formed so that the spacing between the coils can be adjusted.

[0065] The main body (300) provides a magnetic stimulation signal to the applicator (200). The main body (300) generates a stimulation signal with controlled frequency, intensity, pulse width, etc., to respond to various treatment needs. In addition, the main body (300) can store and analyze data collected during operation to monitor and improve treatment effects, and can provide user convenience through a user interface and remote control functions.

[0066] The applicator (200) and the main body (300) are not limited to a special structure and form when constituting the magnetic stimulation system (1000) of the present invention, and it is obvious that various existing TMS applicators and main bodies can be combined with the multi-axis TMS positioning device (100) of the present invention. The method of combining the applicator (200) with the multi-axis TMS positioning device (100) of the present invention may be achieved through an accessory provided on the applicator (200) or through a separate accessory. In other words, the magnetic stimulation system (1000) and the multi-axis TMS positioning device (100) of the present invention include the possibility of combining general-purpose TMS applicators and main bodies, and it is stated in advance that the scope of the present invention is not limited to the configuration of the applicator and main body described through FIGS. 2 to 9 below.

[0067] Hereinafter, the multi-axis transcranial magnetic stimulation (hereinafter, TMS) positioning device (100) of the present invention will be described in detail with reference to FIGS. 2 to 9.

[0068] FIG. 2 is a perspective view illustrating a multi-axis TMS positioning device (100) according to one embodiment of the present invention, FIG. 3 is a side view illustrating a multi-axis TMS positioning device (100) according to one embodiment of the present invention, and FIG. 4 is an exploded perspective view of a multi-axis TMS positioning device (100) according to one embodiment of the present invention.

[0069] The multi-axis TMS positioning device (100) of the present invention is a device that is mounted on the wearer's head and allows the position of the coil to be adjusted in multiple axes to apply transcranial magnetic stimulation (TMS). The multi-axis TMS positioning device (100) is designed to be adjustable to the wearer's head shape and the stimulation area, and ensures consistency and effectiveness of TMS stimulation treatment by precisely controlling and fixing the position of the applicator (200).

[0070] Referring to FIGS. 2 to 4, the multi-axis TMS positioning device (100) of the present invention is composed of a band portion (110), a main frame (120), and a connecting portion (130), and each component enables adjustment optimized for the wearer's head shape and stimulation area.

[0071] The multi-axis TMS positioning device (100) of the present invention includes a band portion (110), a main frame (120) connected vertically to the band portion (110), and a connecting portion (130) connecting the main frame (120) and an applicator (200).

[0072] The band portion (110) is a member that wraps around the wearer's head and is formed to fit snugly along the circumference of the wearer's head. The band portion (110) serves to securely mount the device.

[0073] The band portion (110) may include an elastic material or a length adjustment means so that it can be adjusted to fit the size of the wearer's head circumference.

[0074] The band portion (110) can be precisely adjusted to fit the user's head size through various length adjustment means. For example, a slide-type adjustment means allows for fine adjustment of the length through a rail structure inserted into the band portion, and a fixed click method is included to ensure the adjusted length is stably maintained. Additionally, a belt-type adjustment means can be adjusted in multiple steps with a structure similar to a belt buckle and allows for intuitive operation, and a rolling adjustment means allows for precise adjustment of the band length by turning a dial. Furthermore, a hook-and-loop (e.g., Velcro) means allows the ends of the band portion to be easily attached and detached and fixed at a desired length. The band portion (110) can also accommodate various head shapes of the wearer through various length adjustment means.

[0075] The band portion (110) may be made of a polymer material such as silicone or TPU with excellent elasticity and designed to automatically adhere to various head sizes. This material gently wraps around the head while providing stable fixation, and can maintain comfort even when worn for a long time.

[0076] The band portion (110) can be configured for more precise custom adjustment through a design that combines an elastic material and a length adjustment means. For example, a portion can be formed of an elastic material to gently wrap around the head, while a slide-type adjustment device can be added to allow the length to be adjusted as needed.

[0077] Meanwhile, as shown in FIG. 1, the band portion (110) may include a cushioning material (111) (e.g., a soft pad or cushion) in a weight-supporting part such as the back of the wearer's head to reduce pressure during wear. Additionally, some areas of the band portion (110) may be treated with an anti-slip treatment to increase the wearing stability of the multi-axis TMS positioning device (100) of the present invention.

[0078] The band portion (110) may include a guide member (112) formed to align the position of the device based on the wearer's nose, ears, or specific body part.

[0079] The guide member (112) is a component used to align the position based on body parts such as the wearer's nose and ears, and serves to guide the correct wearing position of the device and support stable fixation. The guide member (112) is a component that helps the multi-axis TMS positioning device (100) of the present invention to be accurately mounted on the wearer's head, and it is preferable that the guide member be designed so that the wearer can intuitively align the stimulation area with the position of the device.

[0080] The guide member (112) illustrated in FIG. 1 is formed to be seated on the wearer's nose and provides a comfortable fit through its soft and ergonomic structure. The guide member (112) is designed to adhere closely to the contour of the nose so that the device is stably fixed without shaking and helps the multi-axis TMS positioning device (100) maintain a consistent position even during treatment. In addition, the guide member (112) aligns the central axis of the device with the position of the nose, thereby guiding the applicator (200) attached to the multi-axis TMS positioning device (100) to be placed at an accurate stimulation position.

[0081] The guide member (112) may include an adjustable structure to fit faces of various sizes and shapes. For example, it may be made of a soft silicone pad or a flexible plastic material and adjusted to the height or width of the wearer's nose. Additionally, it is desirable for the guide member to be designed to optimize the contact area with the wearer to maintain stability even during the transmission of stimulation signals and to avoid irritating the skin.

[0082] These guide members (112) can be formed in a detachable form on the band portion (110).

[0083] The main frame (120) is connected vertically to the band portion (110) and extends in a curved shape from the occipital side of the wearer to the vicinity of the frontal lobe, forming the structural central axis of the multi-axis TMS positioning device (100) of the present invention. The curved main frame (120) is ergonomically designed to naturally wrap around the wearer's skull, enabling stable support and positional movement of the connected applicator (200).

[0084] One side of the main frame (120) is connected to the band portion (110) via the first adjustment portion (140) described later, and the other side of the main frame (120) can be formed in an open state without being connected to the band portion (110). In other words, one side of the main frame (120) is connected to the band portion (110), but the other side of the main frame (120) exists as a free end without being connected to the band portion (110). A structure in which one side of the main frame (120) is connected to the band portion (110) via the first adjustment portion (140) and the other side is formed as a free end without being connected to the band portion (110) provides various important effects. This design has a key structural advantage that allows for covering a wider head range.

[0085] As the other side of the main frame (120) is formed as a free end, the main frame (120) can move more freely compared to a fixed bilateral structure. This means that the main frame (120) can be naturally adjusted to fit the size and shape of the patient's head. Consequently, the application range of the positioning device (100) of the present invention is greatly expanded by allowing customized responses to patients with various head sizes and shapes. In addition, since only one side of the main frame (120) is fixed to the band portion (110) and the other side remains open, the coverage of the main frame (120) from the occipital region to the frontal lobe is maximized, and access to a wider variety of stimulation areas becomes easier than when both sides of the main frame (120) are fixed. In particular, there is an advantage that precise positioning is possible for lateral areas such as the temporal lobe or asymmetrical parts of the head. Because the main frame (120) can rotate or move more flexibly up and down or left and right through the free end, the position of the applicator (200) can be adjusted more precisely. This is combined with the up-and-down movement and rotation functions of the main frame controlled through the first adjustment unit (140), resulting in maximizing the setting range of the stimulation area and increasing accuracy. In addition, due to the free end, the movement of the main frame (120) becomes smoother and more natural, allowing it to flexibly respond to various treatment needs.

[0086] The main frame (120) is designed to be adjustable in multiple axes according to the magnetic stimulation area, allowing for positional movement suitable for various stimulation points. The main frame (120) is configured to be movable in the up-and-down direction at the connection part with the band part (110) and to be rotatable left and right at the connection part with the band part (110). The positional movement of the main frame (120) will be explained in detail below with reference to FIGS. 5 and 6.

[0087] In order to minimize the weight burden applied to the wearer when wearing the multi-axis TMS positioning device (100) of the present invention, it is preferable that the main frame (120) be made of a material that is durable and lightweight.

[0088] The main frame (120) may include rails arranged along the longitudinal direction of the main frame (120). The rails provide a structure that allows the applicator (200) to move along the main frame (120) through a connection part described later.

[0089] The rail can be positioned along the central axis of the main frame (120), and the connecting part (130) is configured to move along this rail. The rail may include a click-stop mechanism that allows the connecting part (130) to stop and be fixed at a specific position. This allows the user to stably maintain the desired position after setting the stimulation area of ​​the applicator (200).

[0090] The connecting part (130) is formed such that one side (131) is connected to the main frame (120) and the other side (132) can be connected to the applicator (200). The connecting part (130) is designed to move along the rail of the main frame (120), thereby providing a function to precisely adjust the position of the applicator (200) according to the set stimulation area.

[0091] One side (131) of the connecting part (130) is stably connected to the main frame (120) and may include a slider or roller structure that can move smoothly along a rail. This structure supports easy adjustment of the position of the applicator according to the stimulation area. Additionally, the connecting part (130) may include a click-stop mechanism or a locking device to stop and fix at a specific position, thereby accurately maintaining the stimulation position set by the user.

[0092] In addition, the connecting part (130) includes a multi-degree-of-freedom rotation or multi-axis rotation structure so that the applicator (200) can rotate or tilt at various angles, thereby flexibly responding to various stimulation requirements.

[0093] The other side (132) of the connecting part (130) is configured to allow an applicator (200) including a magnetic generating coil to be coupled. The other side (132) of the connecting part (130) may include a part to which the applicator (200) can be coupled. This part may be designed to be compatible with various types of applicators.

[0094] The specific structure and positional movement characteristics of this connecting part (130) will be explained in detail with reference to FIGS. 7 to 9 below.

[0095] The multi-axis TMS positioning device (100) of the present invention includes a first adjustment part (140) formed in the part connecting the band part (110) and the main frame (120).

[0096] FIGS. 5 and 6 are drawings for explaining the movement state of the first adjustment unit (140) of a multi-axis TMS positioning device (100) according to an embodiment of the present invention and the main frame (120) accordingly. Specifically, FIG. 5 illustrates a state in which the main frame (120) rotates left and right around the first adjustment unit (140), and FIG. 6 illustrates a state in which the main frame (120) moves up and down in a straight line around the first adjustment unit (140).

[0097] Referring to FIGS. 5 and 6, the first adjustment unit (140) is configured so that the main frame (120) can move up and down and rotate left and right at the connection part with the band unit (110). The first adjustment unit (140) provides the function of flexibly adjusting the position of the main frame (120) and stably fixing it at a set position, thereby enabling customized adjustment for various wearers and stimulation areas.

[0098] The first adjustment unit (140) includes a button (141). The button (141) controls the movement and fixation of the main frame (120) according to user input.

[0099] The main frame (120) is configured to move relative to the band part (110) when the button (141) of the first adjustment part (140) is compressed or released, and the main frame (120) can be fixed relative to the band part (110) when the button (141) is compressed or released in the opposite direction.

[0100] For example, when the button (141) is compressed, the main frame (120) is configured to move freely up and down or rotate left and right relative to the band portion (110), and the user can move the main frame (120) while pressing the button (141) to find the desired stimulation position. Conversely, when the button (141) is released, the main frame (120) is configured to be fixed in a set position and not move, thereby maintaining the stability of the stimulation position of the applicator (200) during treatment. Of course, the button (141) can also be operated in the opposite way to the example described above in the compressed or released state.

[0101] The button (141) of the first adjustment unit (140) contains an internal spring mechanism, so that when the user presses the button, the main frame (120) can be moved, and when the hand is released, the button (141) is automatically restored to its original position to maintain the fixed state of the main frame (120). This design provides both user convenience and safety, and ensures the precision of the stimulated area during treatment.

[0102] Meanwhile, the first adjustment unit (140) may additionally include a click-stop mechanism or a rotation limiting device for controlling the movement of the main frame (120). This allows the rotation angle or range of movement of the main frame (120) to be limited, and enables the user to adjust the movement of the main frame (120) only within a specific range.

[0103] It includes a plurality of indicators (142) designed to visually check and adjust the rotation angle and movement range of the main frame (120). As illustrated in FIGS. 5 and 6, the multi-axis TMS positioning device (100) of the present invention may provide indicators (142) so that a user can accurately set the position and angle of the main frame (120).

[0104] The movement range of the main frame (120) is indicated by values ​​such as +1, -1, etc. in the up and down directions relative to the zero point, so that the user can intuitively check the degree of movement of the main frame (120). This indicator (142) can be subdivided into millimeter (mm) units and includes multiple scales at preset intervals to enable fine adjustment of the stimulation position.

[0105] The rotation angle of the main frame (120) is divided into "Left" and "Right" based on rotational movement in the left and right directions, and may include a range from 0 to 90 degrees. This indicator (142) can be subdivided into units of 5 or 10 degrees and includes multiple scales at preset intervals to enable fine adjustment of the stimulation position.

[0106] The indicator (142) can be manufactured on the main frame (120) or the first adjustment unit (140) using laser printing or engraving techniques. Additionally, a mark or arrow is included next to the indicator (142) to fix or verify the set position, allowing the range of movement and rotation angle to be checked at a glance. This design of the indicator (142) can contribute to improving the precision of the stimulation position and increasing positional reproducibility during treatment.

[0107] FIGS. 7 and 8 are drawings for explaining the movement state of a second adjustment unit (150) and an applicator (200) connected thereto of a multi-axis TMS positioning device (100) according to an embodiment of the present invention. Specifically, FIG. 7 illustrates a state in which a connecting unit (130) and an applicator (200) move along a main frame (120), and FIG. 8 illustrates a state in which a connecting unit (130) and an applicator (200) rotate at multiple angles around the second adjustment unit (150).

[0108] Referring to FIGS. 7 and 8, the second adjustment unit (150) is formed in the part connecting the main frame (120) and the connecting unit (130), so that the applicator (200) can perform multi-degree-of-freedom rotation or multi-axis rotation. The second adjustment unit (150) provides the function of precisely adjusting the position and direction of the applicator (200) and the function of stably fixing it at a set position, thereby enabling customized adjustment for various wearers and stimulation areas.

[0109] The second adjustment unit (150) may include a multi-degree-of-freedom ball hinge structure. The second adjustment unit (150) allows the applicator (200) to freely rotate or tilt in the up-down, left-right, and front-back directions. This ball hinge structure enables the applicator to precisely set various stimulation positions and directions. Additionally, the second adjustment unit (150) may include a rotation limiting device or a stopper to control the degree of freedom of rotation of the applicator (200) so as not to exceed a specific angle.

[0110] The second adjustment unit (150) may additionally include a click-stop mechanism to enhance user convenience. This mechanism allows the applicator (200) to be fixed at a specific position when the user adjusts the rotation angle, thereby maintaining consistency in position during treatment. The second adjustment unit (150) may also include a high-quality bearing or a sliding mechanism with minimized friction resistance to ensure smooth rotation and durability of the applicator (200).

[0111] One embodiment of such a second adjustment unit (150) will be described below with reference to FIG. 9.

[0112] FIGS. 9 and FIGS. 10 are detailed drawings for explaining the configuration of a connecting part (130) and a second adjustment part (150) of a multi-axis TMS positioning device (100) according to an embodiment of the present invention.

[0113] As shown in FIGS. 9 and 10, the second adjustment part (150) is integrally combined with the connecting part (130) to maintain structural consistency and can provide a rotational function of the applicator (200).

[0114] The second adjustment unit (150) includes a ball hinge (151) that acts as a multi-degree-of-freedom hinge, allowing the applicator (200) to freely rotate or tilt in the up-down, left-right, and front-back directions. It is desirable that the ball hinge (151) be made of a material with high durability so as to maintain stability even under repetitive movements.

[0115] A ball hinge (151) may be formed on one side (131) of the aforementioned connecting part (130). As shown in FIG. 9, the ball hinge (151) may be formed integrally with the connecting part (130), or alternatively, it may be arranged in a state connected to the connecting part (130) by a separate connecting member.

[0116] The second adjustment unit (150) may include a stopper (152) formed to surround the ball hinge (151). The stopper (152) restricts the movement of the ball hinge (151) to control the rotation angle of the applicator (200) so that it does not exceed a certain range. The stopper (152) prevents errors that may occur due to excessive movement of the applicator (200) during magnetic stimulation and allows the set angle and direction to be maintained stably. This stopper (152) restricts the rotation angle of the applicator (200) and simultaneously provides the function of fixing the applicator (200) at an angle desired by the user.

[0117] The second adjustment unit (150) may additionally include a rotary handle (153) to adjust the position of the stopper (152) or set a fixed state. The rotary handle (153) serves to rotate the stopper (152) and provides the function of controlling or fixing the range of motion of the ball hinge (151). Through this, the user can set the rotation angle and direction of the applicator (200) more precisely.

[0118] The rotary handle (153) operates through a screw mechanism connected to the stopper (152), and when the user rotates the handle (153), the stopper (152) can adjust the degree to which it wraps around the ball hinge (151). When the handle (153) is tightened, the stopper (152) reduces the rotational range of the ball hinge (151) to increase the fixing force, and conversely, when the handle is loosened, the stopper (152) loosens the ball hinge (151) so that the applicator (200) can rotate freely.

[0119] The function of this second adjustment part (150) provides flexibility in setting the stimulation area and angle of the applicator (200), and allows the position of the applicator (200) to be maintained stably even during treatment.

[0120] The rotary handle (153) is ergonomically designed to enhance user convenience. The handle (153) is preferably treated with a non-slip surface and is preferably made of an appropriate size so that the user can easily operate it with one hand. Additionally, the handle (153) may include a scale mark to visually check the setting status.

[0121] The second adjustment unit (150) may include an indicator (154) that can precisely set and verify the position of the applicator (200) together with a ball hinge (151) rotation structure.

[0122] The indicator (154) is designed to allow visual confirmation of the rotation angle of the applicator (200) and the position moving along the rail, thereby enabling more precise setting of the stimulation area and direction. The indicator (154) visually indicates the angle displayed on the applicator (200), allowing the direction of rotation (left and right) and the angle (e.g., 0° to 90°) to be identified. Additionally, the indicator (154) visually indicates the scale displayed on the main frame (120), allowing intuitive confirmation of the positional movement of the applicator (200), such as +1, -1, etc. relative to the zero point.

[0123] In summary, the indicators (142, 154) of the first adjustment unit (140) and the second adjustment unit (150) are configured to support the user in precisely setting the stimulation position and direction of the applicator (200) and in verifying and reproducing the set values. This plays an important role in increasing the consistency of the treatment effect of the multi-axis TMS positioning device (100) of the present invention and minimizing errors during use. In addition, the indicators (142, 154) provide intuitive visual feedback to enhance the user experience and allow the user to easily check the setting status even during treatment.

[0124] Meanwhile, the connecting part (130) may include a fine adjustment member for adjusting the gap between the main frame (120) and the applicator (200) on the one side (131) or the other side (132). The fine adjustment member is located on the one side (131) or the other side (132) of the connecting part, allowing the user to finely adjust the height of the applicator (200). The fine adjustment member may be formed in various ways, such as an elastic member or a screw-type mechanism.

[0125] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing the technical concept or essential features thereof. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
