Description

Technical Field

[0001] The present application relates to the technical field of temporomandibular joint rehabilitation, and in particular to a temporomandibular joint training device. Background Art

[0002] The temporomandibular joint is the only movable joint in the craniofacial region. Anatomically, the unique articular surface morphology of the condyle, the uneven thickness of the articular disc, and the complex ligamentous muscle attachments surrounding the fossa form a stable and flexible temporomandibular joint. Physiologically, the temporomandibular joint's movements combine both rotational and sliding functions, participating in functional movements such as chewing, speech, and facial expressions. The temporomandibular joint has also been considered an important weight-bearing joint and buffering structure in the maxillofacial region. Temporomandibular joint dysfunction is a common disease of the oral and maxillofacial region. Clinical symptoms include varying degrees of pain in and around the mandibular joint, increased joint pain with clicking when opening the mouth, and mandibular joint movement dysfunction (such as abnormal opening degree and opening type, and locked mouth movement).

[0003] The causes of temporomandibular joint disorder (TMJ) are complex, including psychiatric factors, neurological disorders, occlusal disorders, asymmetric joint development, unilateral poor chewing habits, excessive joint load, trauma, and cold weather.

DETAILED DESCRIPTION

[0040] This application provides a temporomandibular joint training device and a track-based special effects vehicle. To make the purpose, technical solution, and effects of this application more clear and explicit, the application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining this application and are not intended to limit this application.

[0041] like Figure 1 、 Figure 2As shown, the present application provides a temporomandibular joint training device for performing rehabilitation training on the patient's temporomandibular joint. The temporomandibular joint training device mainly includes: a support part 110, a first movable part 200, a second movable part 210 and a third movable part 220. The support part 110 can be worn on the patient and is located on the human head. For the convenience of structural description, the left and right directions after the patient wears the device are used as the left and right directions of the structural description, and the up and down directions and the front and back directions when the patient stands are used as the up and down directions and the front and back directions of the structural description respectively. An accommodating space 120 for accommodating a human face is formed in the support part 110. When the support part 110 is worn on the patient, the head is located in the accommodating space 120. The first movable portion 200 and the second movable portion 210 are both movably connected to the support portion 110 and are respectively located on the left and right sides of the accommodating space 120. Each of the first movable portion 200 and the second movable portion 210 is provided with a force-applying portion 300. The force-applying portion 300 applies force to the first movable portion 200 and the second movable portion 210, respectively, against the sides of the temporomandibular region of the human face. The force-applying portions 300 on both sides provide thrust toward the human face. The third movable portion 220 is movably connected to the support portion 110 and is located at the bottom of the accommodating space 120. The force-applying portion 300 is also provided on the third movable portion 220. The force-applying portion 300 applies force to the third movable portion 220, which is applied to the bottom side of the temporomandibular region of the human face. The force-applying portion 300 on the bottom side provides an upward thrust to the third movable portion 220, allowing it to rest under the chin.

[0042] The main working principle of the temporomandibular joint training device in the above embodiment is: the patient's temporomandibular joint is trained by the training device, the support part 110 is worn on the patient, and the patient's head is located in the accommodating space 120 formed by the support part 110, so that the patient's head is limited by the support part 110, and the patient's head can be straightened, so that the first movable part 200 and the second movable part 210 connected to the support part 110 are respectively located on the left and right sides of the temporomandibular of the human face, and the third movable part 220 on the support part 110 is located on the lower side of the patient's temporomandibular, and the first movable part 200, the second movable part 210 and the third movable part 220 are respectively connected to the force applying part 300, and the force applying part 300 applies force toward the inner side of the accommodating space 120, so as to respectively drive the first movable part 200 and the second movable part 210 The movable portion 200 and the second movable portion 210 respectively rest against the left and right sides of the temporomandibular joint, with the third movable portion 220 resting against the lower side of the temporomandibular joint. When the patient trains the temporomandibular joint, the temporomandibular joint moves toward the left, thereby pushing the first movable portion 200 toward the left. Since the first movable portion 200 provides resistance to the temporomandibular joint's movement toward the left through the force-applying portion 300, to push the first movable portion 200 toward the left, the patient's temporomandibular joint must exert force toward the left to perform resistance exercise, thereby training the temporomandibular joint to move leftward. Correspondingly, only when the patient's temporomandibular joint exerts force toward the right can it push the second movable portion 210 on the right side; and only when the patient's temporomandibular joint exerts force toward the lower side can it push the third movable portion 220 on the lower side to perform resistance exercise of the chin. In this way, training of the leftward and downward movements of the temporomandibular joint is achieved.

[0043] The effect of the temporomandibular joint training device in the above embodiment is: through this temporomandibular joint training device, it is convenient for doctors to perform temporomandibular joint recovery training on patients, improves the training efficiency of patients' temporomandibular joints, allows the temporomandibular joints to move against resistance to the left, right and downward, and has a good training effect.

[0044] like Figure 2 、 Figure 3 、 Figure 5As shown, the force-applying portion 300 in this embodiment specifically includes: a first screw 310, an adjustment nut 320, and an elastic member 330. Taking the force-applying portion 300 connected to the first movable portion 200 as an example for structural description, the first screw 310 is threadedly connected to the support portion 110 in the left-right direction. A stud 311 is provided at the right end of the first screw 310. The stud 311 can be moved in the left-right direction by turning the first screw 310. The first movable portion 200 is provided with a movable groove 231 to accommodate the stud 311. The movable groove 231 extends in the left-right direction. When the temporomandibular force pushes the first movable portion 200, the first movable portion 200 can move along the first screw 310 against resistance. The opening of the movable groove 231 can be configured as a T-shape to prevent the stud 311 from falling out of the movable groove 231. By adjusting the left-right movement of the first screw 310, the first movable portion 200 can be moved closer to or further away from the face within the accommodating space 120, achieving adaptive adjustment based on the patient's different facial shapes. The adjustment nut 320 is threaded onto the first screw 310, and an elastic member 330 is disposed between the first movable portion 200 and the adjustment nut 320. The elastic member 330 can be a spring. The elastic potential energy of the elastic member 330 pushes the first movable portion 200 toward the right, allowing it to rest against the face. When the temporomandibular force pushes the first movable portion 200 leftward, it needs to overcome the elastic force of the elastic member 330, thereby achieving leftward movement of the temporomandibular force against resistance. Moreover, the adjusting nut 320 can be screwed on the first screw rod 310, so that the adjusting nut 320 is close to the first movable part 200 or away from the first movable part 200. When close to the first movable part 200, the adjusting nut 320 squeezes the elastic part 330, causing the elastic part 330 to be compressed. In this way, a greater thrust is required when the temporomandibular mandible moves to the left for resistance exercise, thereby improving the training level of the temporomandibular mandible, thereby realizing the adjustment of the training intensity.

[0045] like Figure 2 、 Figure 3As shown, the support portion 110 in this embodiment includes a bracket body 111, on which at least three adjustment components are respectively provided; an adjustment plate 112 is connected to the adjustment component, and the first movable portion 200, the second movable portion 210, and the third movable portion 220 are respectively connected to the corresponding adjustment plate 112. The first movable portion 200, the second movable portion 210, or the third movable portion 220 moves within the accommodating space 120 through the adjustment component. In the specific structure, the adjustment component is used to adjust the first movable portion 200, the second movable portion 210, and the third movable portion 220 in the front-to-back direction, so that the correct position for temporomandibular training can be found according to the different face shapes of the patient, thereby improving the accuracy of temporomandibular training and improving the training effect. In this embodiment, the adjustment component includes an adjustment screw 113, such as an adjustment bolt. The adjustment plate 112 is provided with a waist-shaped hole extending in the front-to-back direction. At least two adjustment screws 113 pass through the waist-shaped holes and are connected to the bracket body 111. When the adjustment screws 113 are loosened, the adjustment plate 112 can be moved in the front-to-back direction to a suitable position. Then, the adjustment screws 113 are tightened to fix the position of the adjustment plate 112. The first screw 310 of the force-applying portion 300 is threadedly connected to the adjustment plate 112, and the first screw 310 drives the first movable portion 200 to move in the left-to-right direction for position adjustment. This allows the position of the first movable portion 200 to be adjusted in the front-to-back direction and the left-to-right direction, adapting to different patients.

[0046] In this embodiment, the first movable portion 200 and the second movable portion 210 are arranged in mirrored orientations in the left and right directions, with the third movable portion 220 positioned below. This allows for leftward, rightward, and downward resistance-resistance movements of the temporomandibular joint, respectively. The first movable portion 200 specifically comprises a first movable plate 230. A movable groove 231 is defined in the first movable plate 230. A cylindrical body at the left end of the first screw 310 is positioned within the movable groove 231. The length of the movable groove 231 in the left-right direction is greater than the length of the cylindrical body in the left-right direction, enabling the first movable plate 230 to be movably connected to the support portion 110 and slide in the left-right direction. The first movable plate 230 has a curved surface facing the interior of the accommodating space 120. This curved surface is located on the right side of the first movable plate 230, allowing it to rest against the face. This curved surface allows the first movable plate 230 to accurately apply force to the temporomandibular joint during resistance-resistance exercises, enhancing training effectiveness. Furthermore, a flexible cushioning layer is provided on the first movable plate 230. The flexible cushion layer can protect the face.

[0047] like Figure 2 、 Figure 3 、 Figure 4As shown, during the patient's rehabilitation process, it is sometimes necessary to relax the muscles associated with the temporomandibular joint (TMJ). For example, after exerting muscle force during TMJ training, proper relaxation and rest are required. Therefore, the TMJ training device in this embodiment also includes: at least two first massage members 400, at least two second massage members 410, and a third massage member 420. A massage member is a massager, such as a ball massager, that relaxes the muscles by vibrating or squeezing them. The two first massage members 400 are connected to the left and right sides of the support portion 110, respectively. The first massage members 400 are designed to attach to the pterygoid muscles on the face. The first massage members 400 can massage the pterygoid muscles on both sides of the face. The two second massage members 410 are connected to the left and right sides of the support portion 110, respectively, and are located below the first massage members 400. The second massage members 410 are designed to attach to the masseter muscles on the face. The second massage members 410 can massage the masseter muscles on both sides of the face, relaxing the trained masseter muscles. The third massage member 420 is connected to the lower portion of the support portion 110 . The third massage member 420 is used to be attached to the chin of a person's face. The third massage member 420 can massage and relax the muscles of the chin of the person's face.

[0048] The first, second, and third massage members 400, 410, 420 are connected to a support plate 430. Screwed connectors 440 are provided on the support plate 430, allowing the support plate 430 to move forward and backward. This allows for adjustment of the forward and backward positions of the first, second, and third massage members 400, 410, 420. Furthermore, the first, second, and third massage members 400, 410, 420 are also connected to the support plate 430 via screws. Rotating the corresponding screws allows the first and second massage members 400, 410 to be adjusted left and right, while rotating the corresponding screws allows the third massage member 420 to be adjusted up and down.

[0049] In order to achieve the adjustment of the first movable part and the second movable part in the up-down direction, and the adjustment of the first massage part and the second massage part in the up-down direction, the bracket body can be set to a telescopic structure, thereby achieving the adjustment of the first movable part and the second movable part and the first massage part and the second massage part in the up-down direction through telescoping.

[0050] like Figure 6As shown, in another up-and-down adjustment structure, the support portion 110 further includes an up-and-down adjustment block 114, which is respectively connected to the adjustment plate 112 of the first movable portion 200, the adjustment plate 112 of the second movable portion 200, the support plate of the first massage member, and the support plate of the second massage member. Taking the adjustment plate of the first movable portion as an example, the adjustment plate 112 is connected to the up-and-down adjustment block 114 via adjustment bolts. The position of the first movable portion 200 can be adjusted in the front-to-back direction through the waist-shaped hole in the adjustment plate 114. The support body 111 is provided with a waist-shaped hole extending in the up-and-down direction, and the up-and-down adjustment block 114 is connected via screws, so that the up-and-down adjustment block 114 can be connected to the support body 111 and can be moved and adjusted in the up-and-down direction, thereby achieving the up-and-down adjustment of the first movable portion. The other second movable portions, the first massage member, and the second massage member can be adjusted up and down by additional up-and-down adjustment blocks.

[0051] like Figure 7 As shown, the support portion 110 in this embodiment is also provided with a controller 500. The first massage element 400, the second massage element 410, and the third massage element 420 are each electrically connected to the controller 500. The controller 500 is the control body and includes a main controller, a memory, and a drive circuit for the massager. The controller 500 controls the opening and closing of the first massage element 400, the second massage element 410, and the third massage element 420, as well as the massage intensity. The support portion 110 is also provided with a voice prompter 510, which is electrically connected to the controller 500. The controller 500 can provide voice prompts, such as voice prompts for training steps, allowing the patient to follow the voice prompts and complete the corresponding training movements. This allows voice guidance to replace doctor reminders, reducing the doctor's workload.

[0052] In this embodiment, pressure sensors 520 are provided on the side of the first movable portion 200, the second movable portion 210, and the third movable portion 220 facing the accommodating space 120. The pressure sensors 520 are electrically connected to the controller 500. For example, a pressure sensor 520 is provided on the left side of the first movable portion 200, a pressure sensor 520 is provided on the right side of the second movable portion 210, and a pressure sensor 520 is provided on the upper surface of the third movable portion 220. When the patient's temporomandibular movement is detected by the pressure sensors 520 on the movable portions in the corresponding directions, the controller 500 records the force applied during the temporomandibular resistance exercise and compares it with a preset standard value. If the force applied is less than the preset standard value, it is determined that the training has not met the requirements, and a corresponding voice prompt is issued through the voice prompter 510, instructing the patient to apply more force to perform the resistance exercise to achieve the training effect.

[0053] The temporomandibular joint training device in this embodiment also includes a head, shoulder, and neck support member 100. A support portion 110 is disposed on the head, shoulder, and neck support member 100. The head, shoulder, and neck support member 100 is designed to be worn around the patient's neck. The support member 111 of the support portion 110 is made of a rigid material, such as a relatively hard plastic tube, plastic rod, or stainless steel tube. The head, shoulder, and neck support member 100 can be a wearable vest or a relatively tight binding strap. When the head, shoulder, and neck support member 100 is worn on the patient, the support portion 110 is positioned upward, and the patient's head is positioned within the accommodation space 120. A head retaining assembly 130 is disposed on the support portion 110. The head retaining assembly 130 is designed to rest against the user's forehead to retain the patient's head within the accommodation space 120, thereby ensuring that the patient's head is properly aligned. The coordinated use of the head retaining assembly 130 and the head, shoulder, and neck support member 100 ensures that the patient's head, neck, and shoulders are in an optimal alignment during use of the device.

[0054] like Figure 1 、 Figure 2 As shown, the head restraint assembly 130 in this embodiment includes a movable restraint hoop 131, a connecting nut 132, and a forehead pad 133. The movable restraint hoop 131 is configured in an arched shape, with its front end configured as an arc segment. The two ends of the arc segment are connected to straight segments, which are inserted into the support portion 110 and can move on the support portion 110. The connecting nut 132 is threadedly connected to the two ends of the movable restraint hoop 131. Specifically, the straight segment is provided with threads. The connecting nut 132 is threadedly connected to the straight segment. By turning the connecting nut 132, the movable restraint hoop 131 can be moved in the front-to-back direction, thereby adjusting the position of the head. The forehead pad 133 is provided on the arc segment and is located on the side facing the accommodating space 120. The forehead pad 133 can be placed against the forehead to provide protection.

[0055] like Figure 1 As shown, two head limiting assemblies 130 can be provided in this embodiment. The two head limiting assemblies 130 are respectively provided in front of and behind the support portion 110. The two head limiting assemblies 130 are arranged side by side in the up and down directions and respectively limit the forehead and the back of the head.

[0056] The controller in the device may be equipped with a built-in control program to execute corresponding training methods.

[0057] For example, this solution proposes a training method comprising the following steps:

[0058] Step S100: Massage the middle and back part of the patient's face to relax the medial pterygoid muscle by controlling the first massage element to start.

[0059] Step S200: Massage the lower back of the patient's face to relax the masseter muscle by controlling the second massage element to start.

[0060] Step S300: Massage the supralingual muscles of the patient's face by controlling the third massage element to start.

[0061] Step S400: Send a voice message to prompt the patient to press the tongue against the upper palate for 10 seconds and repeat 10 times.

[0062] Step S500: Send a voice message to prompt the patient to move the mandible to the left by 0.1 mm to perform resistance training, last for 10 seconds, and repeat 10 times.

[0063] Step S600: Send a voice message to prompt the patient to move the mandible to the right by 0.1 mm to perform resistance training, last for 10 seconds, and repeat 10 times.
