Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation device for a transcranial magnetic stimulation device with adaptive adjustment function. Background Technology

[0002] Transcranial magnetic stimulation (TMS) is a neuromodulation technique that uses pulsed magnetic fields to act on the central and peripheral nervous systems, generating induced currents that affect the metabolism of the cerebral cortex and neural electrical activity, thereby achieving certain physiological effects.

[0003] In transcranial magnetic stimulation (TMS) therapy, the precise positioning and stable fixation of the stimulation module play a crucial role in the treatment effect. However, most existing TMS devices have fixed fixation structures, which are difficult to adapt to the differences in head shape and head circumference among different patients, resulting in unstable fixation. During treatment, the stimulation module is prone to displacement, affecting the accuracy and effectiveness of stimulation. Therefore, it is necessary to redesign a TMS fixation device with adaptive adjustment function to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a transcranial magnetic stimulation device fixation device with adaptive adjustment function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transcranial magnetic stimulation (TMS) device fixation device with adaptive adjustment function includes an end cap. Two support frames are fixedly mounted on the upper surface of the end cap via a fixing frame. An electric actuator is fixedly mounted inside each of the two support frames. A synchronization controller electrically connected to the two electric actuators is fixedly mounted on the upper surface of each fixing frame. Telescopic openings that mate with the electric actuators are provided on the outer walls of both support frames. Movable plates are fixedly mounted on the telescopic ends of both electric actuators. Pressure sensors are fixedly mounted on the inner walls of both movable plates via a buffer mechanism. A pressure sensor is fixedly mounted on the force-bearing end of each pressure sensor. The first stimulation module has support plates fixedly installed on the front and rear outer walls of the two movable plates. Each support plate has a prismatic rod slidably installed on its outer wall via a sliding mechanism. A connecting sleeve is fixedly installed at one end of each prismatic rod. A connecting plate is fixedly connected inside each connecting sleeve via a connecting mechanism. The second stimulation module is fixedly installed on the outer wall of each connecting plate. A limit plate is fixedly installed at the other end of each prismatic rod. The inner wall of each limit plate is connected to the outer wall of the corresponding support plate via an elastic mechanism. A sponge ring is fixedly installed inside the end cap.

[0007] Preferably, the buffer mechanism includes a spring telescopic rod fixedly installed on the inner wall of the movable plate, and the telescopic end of the spring telescopic rod is fixedly connected to the outer wall of the pressure sensor.

[0008] Preferably, the sliding mechanism includes a bushing fixedly installed on the outer wall of the support plate, and the prismatic rod slides through the bushing.

[0010] Preferably, the adjustment mechanism includes an adjustment spring installed on the outer wall of the prism rod, and the two ends of the adjustment spring are elastically connected to the outer wall of the support plate and the inner wall of the limiting plate, respectively.

[0011] Preferably, a connecting plate is fixedly installed on the outer wall of the end cap, and a backrest sponge block is fixedly installed on the inner wall of the connecting plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as an electric push rod, a spring telescopic rod, and a pressure sensor, the electric push rod drives the moving plate to extend and retract under the control of the synchronous controller, so that the first stimulation module is close to the head. The spring telescopic rod buffers the impact force, and the pressure sensor monitors the contact pressure and feeds it back to the synchronous controller, which precisely adjusts the extension and retraction of the electric push rod to ensure that the stimulation module fits with appropriate pressure, thereby improving the stability and comfort of treatment.

[0014] 2. By setting up components such as a prismatic rod, a ball-head connecting rod, and an adjusting spring, the prismatic rod slides within the bushing and adjusts its position according to the head shape contour. The adjusting spring provides elastic support, allowing the second stimulation module to adapt to and fit the head as the prismatic rod moves. The ball-head connecting rod allows it to rotate in multiple directions to adapt to different head curvatures, expanding its applicability to patients with different head shapes and circumferences, and improving the accuracy and effectiveness of treatment.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A transcranial magnetic stimulation (TMS) device with adaptive adjustment function includes an end cap 1. Two support frames 3 are fixedly mounted on the upper surface of the end cap 1 via a fixing frame 2. Electric push rods 4 are fixedly mounted inside each of the two support frames 3. A synchronous controller 5, electrically connected to the two electric push rods 4, is fixedly mounted on the upper surface of the fixing frame 2. Telescopic openings that cooperate with the electric push rods 4 are provided on the outer walls of both support frames 3. Movable plates 6 are fixedly mounted on the telescopic ends of both electric push rods 4. Pressure sensors 8 are fixedly mounted on the inner walls of both movable plates 6 via a buffer mechanism. A first stimulation module is fixedly mounted on the force-bearing end of the pressure sensor 8. 9. Support plates 10 are fixedly installed on the front and rear outer walls of the two movable plates 6. A prismatic rod 12 is slidably installed on the outer wall of each support plate 10 through a sliding mechanism. A connecting sleeve 13 is fixedly installed at one end of each prismatic rod 12. A connecting plate 15 is fixedly connected inside each connecting sleeve 13 through a connecting mechanism. A second stimulation module 16 is fixedly installed on the outer wall of each connecting plate 15. A limiting plate 17 is fixedly installed at the other end of each prismatic rod 12. The inner wall of each limiting plate 17 is connected to the outer wall of the corresponding support plate 10 through an elastic mechanism. A sponge ring 19 is fixedly installed inside the end cap 1.

[0024] Furthermore, the foam ring 19 is made of soft foam material, which can increase the comfort of the patient when wearing it, and at the same time play a certain role in cushioning and reducing the pressure of the device on the patient's head.

[0025] The buffer mechanism includes a spring telescopic rod 7 fixedly installed on the inner wall of the movable plate 6, and the telescopic end of the spring telescopic rod 7 is fixedly connected to the outer wall of the pressure sensor 8.

[0026] Furthermore, the spring telescopic rod 7 consists of a spring and a telescopic rod. When the moving plate 6 moves the pressure sensor 8 and the first stimulation module 9, the spring telescopic rod 7 can buffer the impact force when the first stimulation module 9 comes into contact with the patient's head, avoiding excessive impact force that may cause discomfort to the patient, while ensuring that the pressure sensor 8 can accurately detect the contact pressure.

[0027] The sliding mechanism includes a bushing 11 fixedly installed on the outer wall of the support plate 10, and a prism rod 12 slidingly passing through the bushing 11.

[0028] Furthermore, the bushing 11 provides a sliding track for the prismatic rod 12, allowing the prismatic rod 12 to slide smoothly within the bushing 11, thereby adjusting its position according to the different head contours of the patients to adapt to the different head shapes of the patients.

[0029] The connecting mechanism includes a ball-head connecting rod 14 rotatably installed inside the connecting sleeve 13, with the end of the ball-head connecting rod 14 fixedly connected to the inner wall of the connecting plate 15.

[0030] Furthermore, the cooperation between the ball-head connecting rod 14 and the connecting sleeve 13 allows the connecting plate 15 and the second stimulation module 16 to rotate within the connecting sleeve 13, achieving multi-directional angle adjustment. This enables the second stimulation module 16 to better conform to different curvatures of the patient's head, improving the adaptability of the device.

[0031] The adjustment mechanism includes an adjustment spring 18 installed on the outer wall of the prism rod 12. The two ends of the adjustment spring 18 are elastically connected to the outer wall of the support plate 10 and the inner wall of the limiting plate 17, respectively.

[0032] Furthermore, the adjusting spring 18 has a certain elasticity. When the prism rod 12 is adjusted according to the patient's head shape, the adjusting spring 18 can provide elastic support, so that the second stimulation module 16 can fit tightly against the patient's head. At the same time, it plays a certain buffering role when the patient's head moves, ensuring the stability of the second stimulation module 16.

[0033] A connecting plate 20 is fixedly installed on the outer wall of the end cap 1, and a back pillow sponge block 21 is fixedly installed on the inner wall of the connecting plate 20.

[0034] Furthermore, the occipital sponge block 21 is made of soft sponge material, which contacts the back of the patient's head, increasing the comfort of the back of the patient's head. At the same time, in conjunction with the sponge ring 19, it allows the device to be worn more stably on the patient's head, reducing the shaking of the device during treatment.

[0035] When using this invention, the end cap 1 can be worn on the patient's head through the sponge ring 19, while the occipital sponge block 21 contacts the back of the patient's head. The sponge ring 19 and the occipital sponge block 21 can increase the patient's wearing comfort and ensure the stability of the device. After wearing, the synchronization controller 5 is activated, which controls the two electric push rods 4 to extend synchronously. The electric push rods 4 push the moving plate 6 to move towards the patient's head. The spring telescopic rod 7 and pressure sensor 8 on the inner wall of the moving plate 6 then approach the patient's head. When the first stimulation module 9 contacts the patient's head, the pressure sensor 8 will detect the pressure signal and feed the signal back to the synchronization controller 5. The synchronization controller 5 adjusts the extension and retraction of the electric push rods 4 according to the pressure signal, so that the first stimulation module 9 fits the patient's head at a specific position with appropriate pressure.

[0036] During the movement of the moving plate 6, the support plate 10 drives the bushing 11 to move, and the prismatic rod 12 slides inside the bushing 11. Due to the different head shapes of patients, the prismatic rod 12 will move according to the head contour. At the same time, the adjusting spring 18 will provide elastic force, so that the second stimulation module 16 can adaptively fit different parts of the patient's head. The ball-head connecting rod 14 inside the connecting sleeve 13 can rotate, so that the connecting plate 15 and the second stimulation module 16 can be adjusted in multiple directions, further improving the adaptability of the device to different head shapes.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
