Description

Technical Field

[0001] This invention relates to the field of health care and rehabilitation training equipment, and in particular to a rehabilitation training device for the temporomandibular joint of the oral and maxillofacial region. Background Technology

[0002] The temporomandibular joint (TMJ) is a vital joint connecting the skull and mandible. Its functions involve chewing, speech, and facial expressions, and it is the only joint in the human body with bilateral coordination. Training the TMJ is crucial for maintaining its function and preventing disease. Common training methods include mouth-opening exercises, mouth-closing exercises, mandibular extension and retraction exercises, and isometric exercises. In TMJ rehabilitation training, a set of braces is placed over the lower teeth. Manually pulling the braces controls the reciprocating movement of the lower teeth, improving occlusion and joint stability. This can significantly enhance TMJ flexibility, muscle strength, and coordination, effectively improving joint position and muscle control. However, without a therapist's guidance, manual pulling of the braces to control TMJ movement can easily lead to excessive force and damage, severely impacting the training effect.

The lower pull ropes 41 are respectively wound around the outside of the corresponding main pulley 22, and the part of the lower pull ropes 41 that is released from the take-up pulley 23 is L-shaped; the two L-shaped lower pull ropes 41 are fixedly connected to the lower teeth 42 between their transverse parts; each of the two mounting blocks 2 is equipped with a control motor 24; the output shafts of the two control motors 24 are respectively fixedly connected to the corresponding take-up pulley 23; each of the two mounting blocks 2 is equipped with a battery module 25, and the battery module 25 is connected to the corresponding control motor 24 through a power transmission line; each of the two fixed rods 21 is rotatably connected to an auxiliary pulley 26; the two lower pull ropes 41 are respectively wound around the outside of the corresponding auxiliary pulley 26, and the auxiliary pulleys are used to cooperate with the main pulley 22 to provide guiding support for the longitudinal part of the L-shaped lower pull ropes 41; the lower teeth 42 is provided with several anti-slip blocks 421, which are in close contact with the lower teeth to prevent slippage during left and right movement training.

[0021] like Figure 2 , Figure 4 and Figure 6 As shown, two mounting blocks 2 are slidably connected to corresponding fixing blocks 1; four elastic locking blocks 27 are fixedly connected to each of the two mounting blocks 2; several slot structures 101 adapted to the elastic locking blocks 27 are opened on each of the two fixing blocks 1; eight elastic locking blocks 27 are respectively tightly attached to the corresponding slot structures 101; an upper quick-release lever 311 is provided between the two upper pull ropes 31 and the upper dental brace 32, and the upper pull ropes 31 are fixedly connected to the upper dental brace 32 through the upper quick-release lever 311; two lower pull ropes Each of the upper and lower braces 42 is provided with a lower quick-release lever 411. The lower pull rope 41 is fixedly connected to the lower braces 42 through the lower quick-release lever 411. After completing the temporomandibular joint rehabilitation training, the upper braces 32 can be removed from the upper pull rope 31 by using the upper quick-release lever 311, and the lower braces 42 can be removed from the lower pull rope 41 by using the lower quick-release lever 411. The removed upper braces 32 and lower braces 42 can then be cleaned and disinfected separately.

[0022] The following is a method of using the oral and maxillofacial temporomandibular joint rehabilitation training device of the present invention.

[0023] First, pull the two mounting blocks 2 forward along the fixed block 1. The mounting blocks 2 drive the elastic locking blocks 27 through the multiple slot structures 101 on the fixed block 1, causing the mounting blocks 2 to move the upper brace 32 and lower brace 42 forward, increasing the width of the training device from front to back to be greater than the width of the front to back of the human head. Then, hang the connecting strap 11 on the back of the neck. The two fixed blocks 1 are respectively attached to the cheeks on both sides of the human body through the silicone pads 12. Then, pull the two mounting blocks 2 backward along the fixed block 1 simultaneously. The mounting blocks 2 drive the elastic locking blocks 27 through the multiple slot structures 101 on the fixed block 1 again, allowing the mounting blocks 2 to move forward. The mounting block 2 moves the upper dental brace 32 and the lower dental brace 42 backward until they are aligned with the positions of the upper and lower teeth of the human body, respectively. At this time, the elastic locking block 27 of the mounting block 2 is locked and fixed in the corresponding slot structure 101. Finally, with the human mouth in a half-open state, the upper dental brace 32 and the lower dental brace 42 are respectively fitted onto the middle of the upper teeth and the middle of the lower teeth. The training device is firmly fitted and fixed on the human head by the connecting strap 11, the two fixing blocks 1, the two mounting blocks 2 and the upper dental brace 32, thus completing the wearing of the training device.

[0024] After the training device is worn, the two control motors 24 alternately drive the two take-up wheels 23 to reciprocate the lower pull rope 41 connected to them. When one control motor 24 controls the take-up wheel 23 to take in the lower pull rope 41, the longitudinal part of the lower pull rope 41 moves backward along the main pulley 22 and the auxiliary pulley 26, while the lateral part of the lower pull rope 41 moves away from the lower brace 42 along the main pulley 22. The lateral part of the lower pull rope 41 pulls the lower brace 42, causing the lower teeth to move in the same direction. Meanwhile, the control motor 24 on the other side controls the take-up wheel 23 to release the lower pull rope 41 connected to it, so that the lateral part of the lower pull rope 41 moves in the same direction as the lower brace 42. This can achieve the goal of moving the lower teeth to one side in the left-right direction under the program setting, and conversely, it can also achieve the goal of moving the lower teeth to the other side in the left-right direction under the program setting. By repeating the above action of moving the lower teeth to the left and right relative to the upper teeth, the temporomandibular joint can be trained to move left and right, thereby enhancing the strength of the masticatory muscles around the temporomandibular joint and the stability of the temporomandibular joint.

[0025] This training device uses electronic instruments to perform specified reciprocating exercises on the temporomandibular joint according to a procedure set by a therapist. While ensuring the effectiveness of the training, it also reasonably controls the force to reduce the risk of joint injury.

[0026] Example 2, this example is based on Example 1 above, such as... Figures 1-6 As shown, each of the two fixed rods 21 has a movable slider 51 slidably connected to it; each of the two movable sliders 51 is fixedly connected to the corresponding fixed rod 21 with an internal compression spring 52, and the internal compression spring 52 is initially in a compressed state; each of the two movable sliders 51 has a pressure rod 53 fixedly connected to its lower end, and the front end of the pressure rod 53 is aligned with the corresponding lower pull rope 41 located in the transverse part between the lower dental brace 42 and the main pulley 22; the lower ends of the two movable sliders 51 are respectively fixedly connected to the corresponding lower pull rope 41 located in the longitudinal part between the main pulley 22 and the auxiliary pulley 26, allowing for left and right movement of the temporomandibular joint. During training, the movable slider 51 is restricted by the longitudinal part of the lower pull rope 41, preventing the compressed inner pressure spring 52 from pushing the movable slider 51 to drive the pressure rod 53 to press the lateral part of the lower pull rope 41 forward. Each of the two pressure rods 53 has a groove structure 530 at its front end, and the groove structure 530 of the pressure rod 53 is aligned with the corresponding lower pull rope 41. After the left and right movement training of the temporomandibular joint is completed, the two control motors 24 drive their connected winding wheels 23 to simultaneously release the two lower pull ropes 41 forward, while the compressed inner pressure spring 52 pushes the movable slider 51. Moving forward along the fixed rod 21, the movable slider 51 drives the pressure rod 53 to lock the lateral part of the lower pull rope 41 through the groove structure 530, preventing the lateral part of the lower pull rope 41 from detaching from the pressure rod 53. The inner pressure spring 52 continues to push the movable slider 51 to drive the pressure rod 53 forward. The pressure rod 53 pushes the locked lateral part of the lower pull rope 41 forward, and at the same time, the lateral part of the lower pull rope 41 drives the lower quick-release lever 411 and the lower dental brace 42 to stretch forward. The lower dental brace 42 drives the lower teeth to stretch forward. Then, the two control motors... 24 drives the connected winding wheel 23 to simultaneously wind the two lower pull ropes 41 backward. At the same time, the lower pull ropes 41 pull the movable slider 51, causing the inner pressure spring 52 to compress and reset backward. Simultaneously, the lateral part of the lower pull ropes 41 drives the lower quick-release lever 411 and the lower dental brace 42 to move and reset backward. The lower dental brace 42 drives the lower teeth to reset backward. The above-mentioned action of the lower teeth moving back and forth relative to the upper teeth is repeated to achieve the forward and backward movement training of the temporomandibular joint, expand the training range of temporomandibular joint movement, and enhance the training effect of temporomandibular joint movement.

[0027] Example 3, this example is based on Example 2 above, such as... Figures 1-8As shown, the lower brace 42 is fitted with two detachable lower clips 61; the upper brace 32 is fitted with two detachable upper clips 62, wherein the upper clips 62 are slidably connected to the upper brace 32 via a rod-like structure. The outer surface of this rod-like structure is covered with a silicone cushioning structure to prevent the rod-like structure from scratching the lips when it reciprocates. Each of the two upper clips 62 is slidably connected to a corresponding lower clip 61. An external pressure spring 63 is fixed between each of the two upper clips 62 and its corresponding lower clip 61. This is done after the temporomandibular joint left-right movement training and before... After the post-exercise training, remove the two lower pull ropes 41 from their respective main pulleys 22. Then, attach the two lower locking blocks 61 to the lower braces 42 and the two upper locking blocks 62 to the upper braces 32. When the upper and lower teeth come together, the upper braces 32 and lower braces 42 together compress the two upper locking blocks 62 and the two lower locking blocks 61 together. At this time, the external pressure spring 63 between the upper and lower locking blocks 62 is compressed, and the temporomandibular joint needs to apply force to overcome the reverse elastic force formed by the compression of the external pressure spring 63 in order for the upper teeth to move together. The upper and lower teeth are in a close occlusal state. When the lower teeth move away from the upper teeth, the compressed external pressure spring 63 pushes the lower locking block 61, causing the lower dental bracket 42 to move downwards with the lower teeth. This repeats the movement of the upper and lower teeth approaching and moving away from each other, thereby training the temporomandibular joint in occlusal activity and further enhancing the strength of the masticatory muscles around the temporomandibular joint and the stability of the temporomandibular joint. An elastic band 64 is fixedly connected between the two lower locking blocks 61, and the elastic band 64 is tightly attached to the inside of the lower dental bracket 42. An elastic band 64 is also fixedly connected between the two upper locking blocks 62. An elastic band 64 is attached to the inside of the upper brace 32. Two lower clips 61 are fixed together by the elastic band 64, and two upper clips 62 are also fixed together by the elastic band 64. The two lower clips 61, two upper clips 62 and two elastic bands 64 together form a whole that fits tightly between the upper brace 32 and the lower brace 42. This improves the firmness of the lower clips 61 and upper clips 62 on the lower brace 42 and the upper brace 32 respectively, and prevents the lower clips 61 and upper clips 62 from loosening during temporomandibular joint occlusal training.
