[0032] Structural features: Mounting plate 201: Usually made of strong metal materials such as stainless steel or aluminum alloy to ensure that it can bear the weight of the entire device and the stress generated.

[0033] It is firmly connected to the wall through multiple bolt holes, and the bolt holes are evenly distributed to provide balanced supporting force.

[0034] As the intermediate connecting part between the mounting plate 201 and the subsequent adjustment components, the connecting plate 202 ensures the smooth transmission of force. It has a certain thickness to ensure structural strength.

[0035] Arc-shaped groove: The opened arc-shaped groove provides space for the bolts to move, facilitating the adjustment of the installation angle.

[0036] The adjustment plate 203, similar to the mounting plate 201, is made of strong and lightweight metal materials.

[0037] It is connected to the folding rod 204 and fixed to the connecting plate 202 through bolts. The number and position of the installation holes are precisely designed and the angle can be adjusted;

[0038] The folding rod 204 and the connecting rod 205 are made of high-strength alloy materials, which can not only ensure strength but also reduce weight.

[0039] The folding rod 204 and the connecting rod 205 are straight rods, and the two are connected by a rotating shaft to ensure that when telescoping and adjusting, the force is evenly distributed and the movement is stable.

[0040] Hollow skeleton structure: It reduces its own weight, does not affect the structural strength at the same time, and reduces the burden on the entire device.

[0041] The adjustment base 206, made of cast steel or aluminum alloy, has sufficient strength and rigidity.

[0042] The internal inlay groove 207 is processed to ensure the installation accuracy and smooth movement of the electric push rod 208 and the moving rod 209.

[0043] The electric push rod 208 can provide precise linear pushing force.

[0044] The moving rod 209 is fixedly connected to the electric push rod 208 at one end and connected to the upper seat 210 at the other end to ensure the effective transmission of force.

[0045] The upper seat 210, the rotating block 211 and the lower seat 212: The rotating block 211 is provided inside the upper seat 210 and the lower seat 212 and is connected thereto through a rotating shaft to form a flexible universal joint structure.

[0046] The pulsed magnetic field stimulator 100: The wearing cap structure: Its shape conforms to the physiological curve of the human head and can closely fit the head.

[0047] The buffer pad: The inner buffer pad is usually made of soft sponge or silicone material and has good buffering and air permeability.

[0048] Functional role:

[0049] The mounting plate 201 and the connecting plate 202 provide a stable mounting foundation to ensure that the entire device will not loosen or shake during use and provide a stable support platform for subsequent adjustment actions.

[0050] The angle adjustment function enables the device to adapt to different installation wall angles and position requirements, increasing the flexibility of installation.

[0051] The adjustment plate 203, by adjusting its relative angle with the connecting plate 202, preliminarily determines the general orientation and position of the device and provides a basis for subsequent fine adjustment.

[0052] The folding rod 204 and the connecting rod 205, the telescopic adjustment function realizes the position change of the pulsed magnetic field stimulator 100 within a large space range and can meet the head positions and treatment needs of different patients.

[0053] The axisymmetric design ensures the balance and stability during the adjustment process and avoids deviation or jamming phenomena.

[0054] The adjustment base 206, the electric push rod 208 and the moving rod 209, the electric push rod 208 provides precise linear pushing force, and by controlling the telescopic length of the push rod, the precise adjustment of the position of the pulsed magnetic field stimulator 100 is realized.

[0055] The sliding of the movable rod within the inlay groove 207 ensures the linearity and stability of the movement, reducing unnecessary wobbling and errors.

[0056] The upper seat 210, rotating block 211, and lower seat 212 form a universal joint structure, enabling the pulsed magnetic field stimulator 100 to freely rotate and tilt in multiple directions, thus better adapting to different angles and postures of the patient's head and ensuring that the magnetic field can accurately act on the target area.

[0057] The pulsed magnetic field stimulator 100 has a cap-like structure, which is convenient for patients to wear and use, improving patient compliance.

[0058] The buffer pad not only increases the wearing comfort but also reduces the pressure of the instrument on the head, avoiding discomfort or injury.

[0059] Working principle:

[0060] Installation stage: Before using the adjustable transcranial magnetic stimulation device, first firmly fix the mounting plate 201 to a suitable wall position with bolts. According to the actual installation environment and usage requirements, determine the initial installation angle by adjusting the positions of the bolts in the arc-shaped grooves on the mounting plate 201 and the connecting plate 202.

[0061] Treatment preparation stage: When the patient is ready to receive treatment, first put on the pulsed magnetic field stimulator 100.

[0062] Adjustment stage: By controlling the telescopic movement of the electric push rod 208, the moving rod 209 is pushed to slide within the inlay groove 207 of the adjustment seat 206, thereby driving the upper seat 210, rotating block 211, lower seat 212, and the connected pulsed magnetic field stimulator 100 to adjust the position horizontally.

[0063] The rotation and telescoping of the folding rod 204 and the connecting rod 205 further expand the adjustable range of the pulsed magnetic field stimulator 100 in space, achieving a large range of position changes.

[0064] Under the action of the universal joint structure composed of the upper seat 210, rotating block 211, and lower seat 212, the pulsed magnetic field stimulator 100 can make fine angle adjustments in multiple directions to ensure precise matching with the patient's head.

[0065] Treatment stage: During the treatment process, doctors or operators can continuously adjust the position and angle of the device according to the patient's real-time feedback and treatment effect to achieve the best transcranial magnetic stimulation treatment effect.

[0066] Such as Figure 1As shown, in some embodiments, the pulsed magnetic field stimulator 100 is a wearable cap structure; the pulsed magnetic field stimulator 100 adopting a wearable cap structure has the following several important features and advantages:

[0067] Conformability: The cap structure can better conform to the contour of the patient's head. Just like a customized hat, it can closely contact various parts of the head, ensuring that the magnetic field can act uniformly on different regions of the head, improving the treatment effect and accuracy.

[0068] Stability: This structure can provide a relatively stable wearing experience. During the treatment process, the patient may have slight movements or head movements, and the wearable cap structure can reduce the displacement and shaking of the instrument, ensuring the continuity and stability of the magnetic field stimulation.

[0069] Comfort: Compared with other fixation methods, the cap design can usually reduce the local pressure on the head, avoiding discomfort or pain. The internal cushioning design can further increase the wearing comfort, enabling the patient to more easily accept the treatment, especially during a long treatment process.

[0070] Convenience: The wearable cap structure is easy for the patient to wear and remove by themselves, and the operation is relatively simple. At the same time, it is also convenient for medical staff to adjust and fix, improving the treatment efficiency.

[0071] For example, in some similar medical devices, such as electroencephalogram detection caps, a similar cap structure is also adopted to achieve good contact and stable detection.

[0072] Such as Figure 3 As shown, in some embodiments, arc-shaped grooves are provided on both the mounting plate 201 and the connecting plate 202, and bolts are used for installation and fixation in the arc-shaped grooves to adjust the installation angle; one is flexibility. The bolts can move to different positions within the arc-shaped grooves, thereby allowing the angle between the mounting plate 201 and the connecting plate 202 to be flexibly adjusted according to actual needs. This is very important for adapting to different installation environments and usage scenarios. For example, if the installation wall is not completely vertical, or the device needs to be aligned in a specific direction, this angle can be adjusted to achieve it.

[0073] Two is stability. When the bolts are tightened at specific positions in the arc-shaped grooves, strong fastening force can be provided to ensure that the mounting plate 201 and the connecting plate 202 remain stable at the selected angle and will not change the angle due to the operation of the device or slight external collisions.

[0074] Three is repeatability. Once a suitable installation angle is determined, the same angle setting can be quickly restored according to the positions of the arc-shaped grooves and the bolts during the next installation or readjustment, ensuring the consistency and reliability of the device usage.

[0075] As Figure 1 shown, in some embodiments, the folding rod 204 and the connecting rod 205 are axially symmetrically adjusted in telescopic position; First of all, the axially symmetric design ensures that during the telescopic adjustment process, the transmission of force and motion is more uniform and balanced. This means that no matter in which direction the device is adjusted in position, the forces received and the displacements generated are relatively symmetric and stable, and there will be no situation where one side is overloaded or the displacement is uneven.

[0076] Secondly, this design helps to improve the accuracy and precision of the adjustment. Due to the uniform distribution of force, the telescopic lengths of the folding rod 204 and the connecting rod 205 can be more precisely controlled, thereby achieving more accurate position adjustment to meet the needs of different patients or treatment scenarios.

[0077] Furthermore, the axially symmetric structure enhances the stability and reliability of the entire adjustment system. During repeated telescopic adjustment processes, it can reduce structural wear, deformation or failures caused by asymmetric forces, and extend the service life of the device.

[0078] As Figure 5 shown, in some embodiments, the moving rod 209 is slidably connected inside the inlaid groove 207; First of all, this sliding connection method provides a clear movement track and guidance for the moving rod 209. When the moving rod 209 makes a telescopic movement, it can move precisely along a predetermined straight line direction, avoiding possible offsets, wobbles or irregular movements, thus ensuring the accuracy and stability of the position adjustment.

[0079] Secondly, the inlaid groove 207 provides good support and protection for the moving rod 209. It reduces the interference of external factors on the movement of the moving rod 209, and at the same time reduces the risk of the moving rod 209 being collided or damaged during the movement process.

[0080] Furthermore, the sliding connection inside the inlaid groove 207 helps to maintain the compactness and aesthetics of the entire structure. It avoids the possible protrusion or mess of the moving rod 209 during the movement process, making the entire device look neater and more orderly.

[0081] As Figure 6 shown, in some embodiments, the upper seat 210, the rotating block 211 and the lower seat 212 form a universal joint structure to adjust the adaptation angle; First of all, this universal joint structure greatly increases the flexibility and freedom of angle adjustment. It can rotate and tilt in multiple directions, enabling the pulsed magnetic field stimulator 100 to perform all-round angle adaptation according to the specific position and posture of the patient's head. Whether it is horizontal adjustment, vertical adjustment or adjustment at any other angle, it can be easily achieved, thus ensuring that the magnetic field can accurately act on the target area.

[0082] Secondly, the universal joint structure can achieve fast and precise angle adjustment. During the treatment process, if fine adjustment of the angle of the stimulator is required, this structure can respond quickly and accurately reach the desired angular position, improving the efficiency and effectiveness of the treatment.

[0083] Furthermore, this structure has good stability and reliability. After completing the angle adjustment, it can firmly maintain the set position and will not change the angle due to slight external interference or the vibration of the device itself, ensuring the continuity and stability of the treatment.

[0084] In this embodiment, a buffer pad is provided inside the pulsed magnetic field stimulator 100; First of all, the buffer pad can increase the wearing comfort. When the patient wears the stimulator, the buffer pad can reduce the pressure generated by the direct contact between the instrument and the head, avoiding excessive pressure on the head and enabling the patient to maintain a relatively comfortable state during the treatment. This is particularly important for patients who need to receive treatment for a long time.

[0085] Secondly, the buffer pad helps to disperse the pressure. The human head is not completely flat, with different convex and concave parts. The buffer pad can adapt to these irregular shapes, evenly distribute the pressure exerted by the instrument on the head surface, reduce local pressure concentration, and thus reduce the risk of discomfort or potential damage caused by uneven pressure.

[0086] Furthermore, the buffer pad can also play a certain shock-absorbing role. During the treatment process, if the patient's head moves slightly or there is a slight vibration from the outside, the buffer pad can absorb and buffer this vibration energy, reducing the vibration felt by the patient and further improving the wearing comfort and stability.

[0087] As Figure 4 shown, in some embodiments, the folding rod 204 and the connecting rod 205 are hollow frame structures, which are lightweight: the hollow frame structure removes some materials and is lighter than the solid structure, helping to reduce the overall weight.

[0088] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
