Description

Technical Field

[0001] This utility model relates to a medical device, and more particularly to a transcranial treatment device. Background Technology

[0002] In the field of physical neuromodulation therapy, precisely delivering therapeutic energy to specific brain regions is crucial for achieving good therapeutic effects. Taking transcranial magnetic stimulation (TMS) as an example, current treatments face numerous challenges. Due to differences in skull shape, lesion location, and hair thickness and density among patients, traditional methods struggle to ensure that stimulation signals are precisely applied to the designated brain regions, making it difficult for the treatment head to accurately target the brain area. This inaccuracy can not only weaken treatment effectiveness and prevent the full realization of the expected neuromodulation effect, but may also cause adverse effects due to incorrect stimulation locations, such as interfering with healthy brain regions or causing slow disease improvement due to insufficient stimulation. Therefore, developing a treatment helmet capable of more precise positioning in transcranial therapy has become a key focus of the industry.

[0003] Transcranial therapy utilizes advanced imaging data acquisition methods, such as magnetic resonance imaging (MRI) or computed tomography (CT), to obtain detailed head data of the subject. This includes the head's external contour (including the scalp), internal structures (bones and brain regions), and the location of lesions (the brain regions requiring treatment), and constructs a high-precision three-dimensional model. Based on human anatomy and neurological principles, specialized medical imaging analysis software is used to precisely determine the coordinates of the target brain regions to be treated on the head model. This positioning process is based on the brain's functional neural regions and disease-related abnormal neural pathways, providing indispensable positioning data for subsequent helmet design and treatment implementation, ensuring that therapeutic energy is precisely applied to the affected brain regions, such as... Figure 1 As shown, to maximize the therapeutic efficacy and reduce potential adverse effects on normal brain regions, the position of the treatment head (position 4) in the figure corresponds to the lesion point (position 3).

[0004] Existing technologies include three-point positioning solutions using the front and sides of the helmet. However, these solutions require at least one assistant to observe and adjust from a side-view perspective to ensure accurate helmet wearing. When there is a shortage of personnel or when patients do not trust the assistant, the efficiency of helmet wearing is affected, hindering further treatment. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a more convenient helmet for transcranial therapy, which enables patients to accurately wear the helmet by themselves, thus ensuring the treatment effect and greatly improving the convenience and efficiency of accurate wearing.

[0006] To solve this technical problem, the technical solution adopted by this utility model is as follows:

[0007] A transcranial therapy helmet includes a helmet body, a nasofrontal angle positioning structure is provided at the middle of the front end of the helmet body, and an ear hole positioning ring is provided on each side of the helmet body at the position of matching the ear holes. The ear hole positioning ring has a positioning hole in the middle. The patient can judge and adjust whether the ear hole positioning ring is aligned with the correct wearing position by using a finger or a columnar object to insert into the ear hole.

[0008] Furthermore, the nasofrontal angle positioning structure is shaped like a downward-convex pointer. When viewed from the side, its inner wall tapers downward to match the contour of the patient's nasofrontal angle, and its thickness gradually decreases as it extends downward. When viewed from the front, a vertical mark is provided at the center of the lower part of the outer wall of the nasofrontal angle positioning structure. The vertical mark is used to align with the midline of the face when the helmet is worn accurately, so that the point pointed to by the vertical mark at the lower end of the nasofrontal angle positioning structure matches and coincides with the center position of the patient's nasofrontal angle.

[0009] Furthermore, the lower end of the nasofrontal angle positioning structure is arc-shaped when viewed from the front.

[0010] Furthermore, the helmet is designed to match the inner wall of the part above the most prominent point of the patient's occipital bone with a positive tolerance of 0-1.9mm between the size of the inner wall and the size of the patient's scalp.

[0011] Furthermore, the helmet is designed to match the inner wall of the part above the most prominent point of the patient's occipital bone with a positive tolerance of 3.6-12mm between the size and the size of the patient's scalp.

[0012] Furthermore, the vertical mark can be a protruding line, a groove, or a planar line.

[0013] The speed and accuracy of wearing a transcranial therapy helmet directly impacts treatment outcomes. Current helmets require assistance from additional medical personnel or others for observation and adjustment to ensure accurate placement. This is because existing helmets use a centering pointer in the ear canal for alignment, necessitating observation and adjustment from a side-view perspective for lateral positioning of the ear canal. However, in practice, situations often arise where the patient is alone and there are insufficient medical staff available for assistance. This necessitates waiting for someone else to assist, often wasting medical resources and hindering timely treatment.

[0014] The transcranial therapy helmet of this invention cleverly features unique ear hole positioning holes (without a central positioning pointer in the middle of the hole) at the positions of the ear holes on both sides of the helmet. These positioning holes are suitable for patients to insert their own fingers (or for patients to insert matching cylindrical objects, and then judge the alignment of the helmet by feeling the positional relationship between their fingers after passing through the positioning holes and the ear holes, thereby quickly adjusting and correcting the position of the helmet).

[0015] In this way, patients can independently and accurately put on the treatment helmet on their own. Patients can first use the ear hole positioning rings to position the helmet. Based on the relatively fixed position of the human ear hole, the center of the ear hole positioning rings coincides with the patient's ear hole when the helmet is worn correctly. The patient's fingers can pass through the positioning rings and accurately touch the ear hole, which indicates that the helmet is in the correct position on that side, thus ensuring the accurate positioning of the helmet on both sides of the head.

[0016] Subsequently, the patient can use a mirror to locate the nasofrontal angle positioning structure. The nasofrontal angle positioning structure is designed as an indicator extending downward from the forehead of the helmet. Its principle is based on human head anatomy and the working principle of the treatment instrument. When the helmet is worn correctly, its central axis is precisely aligned with the midline of the patient's face. At this time, when viewed from the side, the bottom of the nasofrontal angle positioning structure is at the same level as the nasofrontal angle (the most concave part between the bridge of the nose and the brow bone). When viewed from the front, the middle position of the bottom of the nasofrontal angle positioning structure coincides with the center position of the patient's nasofrontal angle.

[0017] The three-point positioning calibration mechanism described above can lock the accurate wearing position of the helmet. When using the helmet of this utility model, the three-point precise positioning can be completed by an individual alone without relying on the guidance, cooperation and adjustment of others. This not only lays a solid foundation for precision treatment and ensures that the treatment instrument accurately acts on the brain treatment area, but also greatly improves the convenience and efficiency of precise wearing.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0031] Figure 2 , Figure 3 A transcranial therapy helmet is shown, including a helmet body 100. A nasofrontal angle positioning structure 1 is located at the center of the front end of the helmet body. The nasofrontal angle positioning structure 1 is convex, pointer-shaped, and extends downwards from the forehead of the helmet. Viewed from the side, its inner wall tapers downwards to match the contour of the patient's nasofrontal angle, and its thickness gradually decreases as it extends downwards. Viewed from the front, a raised vertical mark 101 is located at the center of the lower part of the outer wall of the nasofrontal angle positioning structure 1. The vertical mark 101 is used to align with the midline of the face when the helmet is worn correctly, so that the point pointed to by the vertical mark 101 at the lower end of the nasofrontal angle positioning structure 100 exactly matches and coincides with the center position of the patient's nasofrontal angle. Figure 4 As shown.

[0032] The raised vertical mark 101 can also be a groove, or simply a vertical planar line painted on the center of the nasofrontal angle positioning structure 1, as long as the patient can clearly observe the position of the vertical mark 101 through a mirror.

[0033] The helmet body 100 has an ear hole positioning ring 2 at the position of matching the ear holes on both sides. The ear hole positioning ring 2 has a positioning hole 201 in the middle. The patient can judge and adjust whether the ear hole positioning ring 2 is aligned and worn correctly by using a finger or a columnar object to pass through the positioning hole 201 and see if it is accurately inserted into the ear hole.

[0034] Given the different transcranial treatment devices and treatment methods used, transcranial treatment is basically divided into two types: large treatment heads and small treatment heads. These correspond to large transcranial treatment devices (using a single treatment head) and small portable transcranial treatment devices (generally using multiple treatment heads, with multiple treatment head ports on the helmet).

[0035] Since the helmet body 100 is manufactured based on a head mold replicated from imaging data, appropriate tolerances must be considered when wearing it. Due to individual differences, to ensure a smooth fit, the dimensions of the helmet's inner wall are generally left with a positive tolerance relative to the patient's head size (this discussion mainly focuses on the inner wall of the helmet above the most prominent point of the patient's occipital bone, which is also the area where we set the treatment head opening; while for a smooth fit, helmets below the most prominent point of the occipital bone are often designed in a cylindrical shape to facilitate head entry). This positive tolerance refers to enlarging the replica model's scalp as a reference before manufacturing the helmet, ensuring a perfect fit between the helmet's inner wall and the patient's scalp, or allowing for a certain gap. However, this positive tolerance cannot be too large. If the enlargement is too great, the helmet will be too loose, causing inaccurate positioning points; conversely, if the enlargement is insufficient, it may cause jamming and prevent the helmet from being worn due to individual differences. The inner wall dimensions of the helmet must be enlarged to an appropriate scale.

[0036] For small treatment heads, we use a type A helmet, such as... Figure 5 As shown, the inner wall of the Type A helmet, above the most prominent point of the patient's occipital bone, has a positive tolerance of δ1 = 0-1.9 mm between its dimensions and the patient's scalp dimensions. Ensuring a proper fit of the helmet's inner wall makes it easier to ensure the working surface of the treatment head is closer to the patient's scalp, thus resulting in an effective and stable treatment outcome.

[0037] Because the inner wall of the helmet fits the scalp better when using the small treatment head, we set the lower end of the nasofrontal angle positioning structure 1 to be arc-shaped when viewed from the front, which can be semi-circular, so that the lower end of the nasofrontal angle positioning structure 1 will not poke the patient during use.

[0038] For large healing heads, we use Type B helmets, such as... Figure 6 As shown, the B-type helmet has a positive tolerance of δ2 = 3.6-12mm between the inner wall size of the part above the most prominent point of the occipital bone and the size of the patient's scalp. Given the large size and complex structure of the treatment head of large treatment instruments, more space is required for its accommodation and adaptation; the adjustment of treatment equipment and treatment head is more limited. A larger range of magnification can flexibly handle various situations, and the pre-reserved clamp interfaces or special holes in the helmet structure to adapt to large treatment heads ensure that the treatment head can be accurately positioned in different usage scenarios, guaranteeing that the scalp can be touched even when using a large treatment head, achieving precise treatment.

[0039] In clinical treatment or scientific research scenarios, when using helmet A or helmet B of this utility model in conjunction with transcranial magnetic stimulation, transcranial ultrasound, or other applicable treatment instruments, the helmet should be worn according to the following steps:

[0040] 1. Initial wearing: Place helmet A or helmet B on the patient's head, pay attention to the contact between the helmet and the head to avoid discomfort, and at the same time pay attention to the relative position of the nasofrontal angle positioning structure 1 and the ear canal positioning ring 2 with the corresponding parts of the head to prepare for calibration.

[0041] 2. Ear cannula calibration: The patient inserts their finger through the positioning hole 201 and observes the direction of the finger. The helmet is then finely adjusted according to the direction and degree of deviation. This process is repeated until both ear canals are accurately calibrated. For example, if the fingertip deviates forward from the ear canal after the patient's finger is inserted through both positioning holes 201, the helmet is moved back, and the finger direction is checked again until the finger accurately points to the ear canal.

[0042] 3. Nasofrontal angle calibration: The patient can observe in a mirror whether the lower end of the vertical mark 101 coincides with the center of the nasofrontal angle. If it does not meet the requirements, carefully adjust the front and back position of the helmet to ensure that the calibration conditions are met.

[0043] 4. Verification: Recheck the position of the ear piercing and the frontal angle of the nose. After confirming that everything is correct, wear helmet A or helmet B accurately. Then, start the treatment instrument to carry out treatment or experiments to ensure the treatment effect and the accuracy of the experimental data.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
