Abstract
Description
Technical Field
[0001] This invention relates to a medical device, and more particularly to a transcranial magnetic stimulation device. Background Technology
[0002] Transcranial magnetic stimulation (TMS) is a non-invasive neuromodulation technique with few side effects, playing a significant role in cognitive neuroscience and clinical neurofunctional regulation. TMS utilizes a time-varying magnetic field generated by pulsed currents to induce an electric field within brain tissue, thereby modulating neuronal excitability and stimulating specific functional cortical areas to treat various brain diseases.
[0003] After decades of development and application, transcranial magnetic stimulation (TMS) has achieved good therapeutic effects in many areas of neuromodulation, supported by a wealth of literature. Furthermore, it has gained widespread recognition from physicians in relevant departments during clinical use.
[0004] Transcranial magnetic stimulation (TMS) devices are divided into traditional TMS devices and portable TMS devices that have emerged in recent years. Hospitals and other institutions generally equip themselves with a certain number of traditional TMS devices. Although traditional TMS devices are not convenient to move due to their size and weight, and their operation is relatively cumbersome and requires high standards, their therapeutic intensity and effect cannot be replaced by portable TMS devices due to their power limitations.
[0005] However, in actual clinical application, some difficulties have been encountered, preventing the full realization of the therapeutic effects of transcranial magnetic stimulation (TMS) and thus hindering the benefit to more patients. The main problem lies in the high skill requirements placed on operators during TMS use, particularly in the precise localization of treatment targets. Although operators, including those in primary healthcare units, have received some training and can locate the appropriate treatment sites, achieving optimal therapeutic effects (as evidenced by experimental results reported in many top domestic and international journals) requires replicating the precise treatment targets observed in experiments. This necessitates strong operational skills from the operator; otherwise, the actual results often differ significantly. In practice, some effective methods exist to address this issue, such as advanced treatment navigation instruments. These instruments can analyze patient MRI data to plan treatment in advance, enabling rapid, accurate, and convenient placement of the TMS head onto the corresponding treatment targets without requiring highly specialized skills from the operator. However, these advanced navigation instruments, whether imported or domestically produced, often cost two to three million yuan each, making them unaffordable for many hospitals with the need, resulting in extremely low adoption rates.
[0006] Besides the aforementioned issues with precise positioning capabilities, another significant contradiction is that an experienced and skilled operator often spends about an hour just positioning the machine when treating a patient (and if the patient accidentally moves their head during treatment, repositioning is required). This means that even a highly skilled doctor cannot treat many patients in a day. This further widens the actual gap and contradiction between supply and demand, leaving the actual treatment needs of a large number of patients unmet.
[0007] In conclusion, in order to better leverage the therapeutic effects of transcranial magnetic stimulation (TMS) and enable more patients to achieve good therapeutic results and improve their quality of life, the market urgently needs an affordable, simple, and effective precise positioning device to address this issue. Summary of the Invention
[0008] The technical problem to be solved by this invention is to provide a unique and practical transcranial magnetic stimulation (TMS) device precision treatment positioning adapter, which can accurately and conveniently position the treatment head of a large TMS device to the target point where the patient needs treatment. It is simple, convenient, accurate and effective, thereby greatly reducing the doctor's operation time and improving the therapeutic effect, so that more patients can benefit from it.
[0009] To solve this technical problem, the present invention adopts the following technical solution:
[0010] A transcranial magnetic stimulation (TMS) device precision treatment positioning adapter includes a head cover base and at least one treatment head positioning and fixation structure.
[0011] The treatment head positioning and fixing structure is as follows: a treatment head gap matching the shape of the treatment head is provided at the predetermined treatment position on the head cover base; a treatment head locking and fixing structure is provided on the outer surface of the head cover base at the edge of the treatment head gap, which can stably hold the treatment head and allow the treatment surface of the treatment head to pass through the treatment head gap and fit against the patient's head.
[0012] Furthermore, the treatment head locking and fixing structure includes at least two handle posts, and the handle of the treatment head can be matched and locked between the two handle posts.
[0013] Furthermore, the treatment head locking and fixing structure also includes at least one limiting post disposed opposite to the handle post, and the treatment head can be stably locked between the handle post and the limiting post.
[0014] Furthermore, the treatment head locking and fixing structure also includes an annular treatment head adapter base, which is detachably inserted into the outer surface of the head cover base and the edge of the treatment head cavity via a pin hole structure; the handle post and the limiting post are fixedly disposed on the outer surface of the treatment head adapter base.
[0015] Furthermore, all the handle posts are fixedly mounted on the first post fixing plate, and the first post fixing plate is radially and adjustablely connected to the treatment head adapter base; the limiting post is fixedly mounted on the second post fixing plate, and the second post fixing plate is radially and adjustablely connected to the treatment head adapter base; thereby enabling the treatment head to be precisely and stably matched and positioned between the handle posts and the limiting post.
[0016] Furthermore, a base locator is provided at the front end of the headgear base, and the base locator has a positioning indicator end. When the patient wears the positioning adapter correctly, the positioning indicator end is exactly matched with the patient's brow.
[0017] Furthermore, the locator body is rhomboid in shape, with its downward-pointing acute angle being the positioning indicator end.
[0018] Furthermore, the headgear base is custom-made to fit the shape of the patient's head.
[0019] The manufacturing and usage methods of the transcranial magnetic stimulation device's precision treatment positioning adapter are as follows.
[0020] I. Production Method:
[0021] 1. Obtain a suitable headgear substrate.
[0022] 2. Set up a treatment head vacancy at the predetermined position on the headgear base.
[0023] 3. A treatment head positioning and fixation structure is set on the headgear base.
[0024] II. Instructions for use:
[0025] 1. Patients should wear the transcranial magnetic stimulation device's precise treatment positioning adapter accurately.
[0026] 2. The treatment head of the traditional transcranial magnetic stimulation device is properly inserted into the treatment head positioning and fixing structure, with the treatment surface of the treatment head conforming to the patient's head.
[0027] 3. Turn on the transcranial magnetic stimulation device to provide precise treatment to the patient's target points.
[0028] Furthermore, the predetermined position of the headgear base can be calculated and determined based on the patient's individual CT or MRI imaging data.
[0029] The positioning adapter of this invention can quickly, accurately, and effectively solve the problem of accurate positioning of the treatment head of a transcranial magnetic stimulation (TMS) device, enabling TMS to act more precisely on the patient's treatment target point, unaffected by the operator's experience or professional skills. This makes the placement of the treatment head simple, convenient, accurate, and effective, thereby greatly reducing the doctor's operation time and improving the therapeutic effect, allowing more patients to benefit from it.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0045] Figure 1 It is a type of transcranial magnetic stimulation device commonly used in major medical institutions, consisting of a main body and a treatment head connected by cables.
[0046] Figure 2 A transcranial magnetic stimulation (TMS) device precision treatment positioning adapter is shown. When a patient needs treatment, simply wearing this adapter allows the treatment head 2 of the MMS device to be easily, quickly, stably, and accurately positioned at a predetermined location on the patient's head, significantly reducing the doctor's operation time and improving efficacy. The positioning adapter includes a headgear base 1 and at least one treatment head positioning and fixing structure (only one structure is needed if the patient only needs treatment at one location; multiple structures can be used if the patient needs treatment at two or more locations without conflict). The treatment head positioning and fixing structure consists of a treatment head locking and fixing structure on the outer surface of the headgear base 1 at the edge of the treatment head slot 101, which stably holds the treatment head 2 and allows the treatment surface 201 of the treatment head 2 to pass through the treatment head slot 101 and fit against the patient's head 3. Figure 3 As shown. The center of the treatment head vacancy 101 is the center of the treatment surface 201 after the treatment head 2 is matched and set, which is the pointing position of the treatment target point.
[0047] Since the shape of the headgear base 1 can vary, as long as it can be stably fixed to the patient's head 3 and the treatment head locking and fixing structure can be stably set, it is acceptable. When the headgear base 1 is a hemispherical headgear, the treatment head vacancy 101 is a round hole or other shape that matches the treatment head. When the headgear base 1 is a frame structure, the treatment head vacancy 101 can be an open vacancy.
[0048] like Figure 1 , Figure 2 As shown, the treatment head locking and fixing structure can be specifically structured as follows: it includes two handle posts 4, and the handle 202 of the treatment head 2 can be matched and locked between the two handle posts 4. Of course, multiple handle posts 4 can also be provided to facilitate the locking of certain handles 202.
[0049] When the treatment head 2 is matched and locked between the handle post 4 by the handle 202, but is not stable enough, the treatment head locking and fixing structure may further include at least one limiting post 5 (which may be one or more) disposed opposite to the handle post 4, so that the treatment head 2 can be stably locked between the handle post 4 and the limiting post 5.
[0050] The aforementioned handle post 4 and limiting post 5 can be directly fixed to the headgear base 1, or they can be detachably fixed to each other via an annular treatment head adapter base 6. The treatment head adapter base 6 is detachably inserted into the outer surface of the headgear base 1, at the edge of the treatment head slot 101, via a pin hole structure. The handle post 4 and limiting post 5 are fixed to the outer surface of the treatment head adapter base 6, as shown below. Figure 4 , Figure 5 As shown.
[0051] When the curvature of the head is relatively small at the location of the treatment head gap 101, the treatment head adapter base 6 may be too thick due to the overlap of the head cover base 1 and the treatment head adapter base 6, which may prevent the treatment surface 201 of the treatment head 2 from fitting the patient's head. In this case, a groove needs to be cut into the outer surface of the head cover base 1, and the treatment head adapter base 6 is embedded into the groove to reduce the thickness of the assembled parts, so that the treatment surface of the treatment head 2 can fit the patient's scalp after installation.
[0052] To ensure a more stable placement of the treatment head 2 on the treatment head adapter base 6, the outer surface of the treatment head adapter base 6 is generally flat. However, the curvature of the patient's head 3 at the predetermined treatment position where the treatment head vacancy 101 is located may be relatively large. In this case, the following structural solutions can be adopted: the inner surface of the treatment head adapter base 6 adopts a curved shape that matches the curvature of the head; or the head cover base 1 is provided with a raised platform at this location to accommodate the flat, annular treatment head adapter base 6; or the head cover base 1 is provided with several pin-hole posts 103 at this location to match the positioning pins at the bottom of the annular, flat treatment head adapter base 6 (e.g., ...). Figure 6 (As shown).
[0053] like Figure 7As shown, since the shape and size of the treatment head 2 of the device applicable to patients may vary, in order for one adapter to accommodate multiple treatment heads 2, the handle column 4 and the limiting column 5 can adopt a radially adjustable structure: all the handle columns 4 are fixedly mounted on the first column fixing plate 7, and the first column fixing plate 7 is fixedly connected to the treatment head adapter base 6 in a radially adjustable position; the limiting column 5 is fixedly mounted on the second column fixing plate 8, and the second column fixing plate 8 is fixedly connected to the treatment head adapter base 6 in a radially adjustable position; thereby enabling the treatment head 2 to be accurately and stably matched and positioned between the handle column 4 and the limiting column 5. During installation, the first column fixing plate 7 and the second column fixing plate 8 can be adjusted and fixed when the treatment head 2 is in the standard treatment position (i.e., the center of the treatment surface 201 of the treatment head 2 coincides with the center of the treatment head vacancy 101), so that the positioning adapter can accurately and stably adapt to this treatment head 2. When a patient needs to be fitted with another treatment head 2 that has a different shape and size, it is necessary to repeat the operation of aligning, adjusting and fixing the first column fixing plate 7 and the second column fixing plate 8 with the treatment head 2.
[0054] The first column fixing plate 7, the second column fixing plate 8, and the treatment head adapter base 6 can be fixedly connected in a radially adjustable manner in various conventional forms. Figure 7 The diagram shows a structural configuration: a first column fixing plate 7 and a second column fixing plate 8 are pressed onto a treatment head adapter base 6. The first column fixing plate 7 and the second column fixing plate 8 are provided with internal thread fixing holes. The treatment head adapter base 6 has an oval hole extending radially along the treatment head adapter base 6 at a position corresponding to the internal thread fixing hole. Fixing screws pass through the oval hole and are fixedly connected to the internal thread fixing hole, thereby achieving radial positional adjustability of the first column fixing plate 7 and the second column fixing plate 8.
[0055] Furthermore, to ensure that the patient can accurately wear the headgear base 1 each time they use the positioning adapter, and that the treatment head slot 101 is precisely positioned in the "predetermined treatment location," a base locator 102 is provided at the front end of the headgear base 1. The base locator 102 has a positioning indicator end, which aligns perfectly with the patient's brow when the patient wears the positioning adapter correctly. Thus, each time the patient uses the adapter, as long as it is worn stably and the positioning indicator end is aligned with the patient's brow, the precise position of the headgear base 1 can be quickly and effectively adjusted. The locator 102 is rhomboid in shape, with its downward-pointing acute angle being the positioning indicator end. Of course, the locator 102 can also adopt other conventional structural forms, as long as it serves as an auxiliary guide for position correction when wearing the headgear base 1.
[0056] The aforementioned headgear base 1 is a custom-made form, designed to fit the shape of a specific patient's head 3. Customization can be achieved by creating a 3D model of the headgear base 1 based on scan data of the patient's head 3, and then manufacturing a personalized headgear base 1 that accurately fits the specific patient's head 3 using 3D printing. Alternatively, other customization methods can be used to obtain a personalized headgear base 1. Then, based on the medical scan data of the patient's head, treatment target points are determined, thereby determining the predetermined treatment position for placing the treatment head 2, and creating a treatment head vacancy 101 that matches the shape of the treatment head 2.
[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention 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 the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
