Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an oral and maxillofacial rehabilitation training device. Background Technology

[0002] Oral and maxillofacial dysfunction is commonly seen in various conditions such as temporomandibular joint disorder, post-oral tumor surgery, and post-maxillofacial trauma. Patients often present with symptoms such as limited mouth opening, weak chewing, and abnormal mandibular movement, which severely impacts their quality of life. Rehabilitation training is the core means to improve these functional impairments, and oral and maxillofacial rehabilitation training devices have been widely used as important assistive tools.

[0003] Chinese patent CN120859809B discloses a temporomandibular joint rehabilitation training device for the oral and maxillofacial region. It is mainly fitted and fixed to the head using a fixing block, connecting strap, mounting block, and upper dental brace. A control motor drives a retractor to perform asynchronous or synchronous reciprocating movements of the lower pull rope, thereby controlling the lower dental brace to pull the lower teeth to train the temporomandibular joint's lateral and anterior-posterior movements. However, the existing technology suffers from the limitation of training only the temporomandibular joint, failing to train other areas. Therefore, a new oral and maxillofacial rehabilitation training device is needed to solve this problem. Summary of the Invention

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1-8As shown, the oral and maxillofacial rehabilitation training device of the present invention includes a left wearing seat 1, a right wearing seat 2, a wearing mechanism 3, a portable training mechanism 4, and an impedance training mechanism 5. The wearing mechanism is connected to the left and right wearing seats on both sides and can rotate on the left and right wearing seats respectively. The portable training mechanism is fixedly mounted on the left and right wearing seats on both sides respectively. The portable training mechanism and the impedance training mechanism are detachably connected. The portable training mechanism includes a first connecting rod 41, a second connecting rod 42, a third connecting rod 43, a fourth connecting rod 44, an upper training component 45, and a lower training component 46. The two ends of the upper training component are connected to the first and second connecting rods respectively. The two ends of the lower training component are fixedly connected to the third connecting rod and the fourth connecting rod respectively. The other ends of the first and second connecting rods are fixedly mounted on the left and right wearing seats respectively. The third and fourth links are respectively rotatably mounted on the left and right wearing seats; soft pads are fixed on the inner sides of the left and right wearing seats to fit the patient's facial skin and increase wearing comfort; the portable training mechanism can perform impedance-free training, and is small in size and lightweight for easy carrying, making it suitable for patients in the early postoperative rehabilitation training stage; the impedance training mechanism needs to be connected to the portable training mechanism to increase the impedance during training, making it suitable for patients in the mid-to-late postoperative rehabilitation training stage; the portable training mechanism can perform bite training and lip muscle training. Compared with the existing technology that only trains the temporomandibular region, this invention can also train the lip muscles, such as assisting the patient in pouting and grinning to train the lip muscles; the first to fourth links are all arc-shaped rods, with the upper training component contacting the upper lip and upper teeth during training; the lower training component contacting the lower lip and lower teeth during training.

[0026] Specifically, the upper training component includes an upper occlusal seat 451, an upper occlusal pad 452, a first sliding groove 453, a second sliding groove 454, a first sliding seat 455, a second sliding seat 456, a first lip plate 457, and a second lip plate 458; the upper occlusal pad is fixedly mounted on the upper occlusal seat; the two ends of the upper occlusal seat are respectively fixedly connected to a first connecting rod and a second connecting rod; the first sliding groove and the second sliding groove are respectively fixedly mounted on the first connecting rod and the second connecting rod; the first sliding seat and the second sliding seat are respectively slidably mounted on the first sliding groove and the second sliding groove; the first lip plate and the second lip plate are respectively fixedly mounted on the first sliding groove and the second sliding groove. The first slide and the inner sides of the second slide; the upper occlusal seat is arc-shaped from a top view and has a short width, corresponding to the patient's upper central incisors and lateral incisors. In the prior art, full-size occlusal seats are used, but due to the different positions and arrangement curvatures of the canines and molars of different patients, the fit is not good. However, the incisors of different patients are all located in the center and have a small arrangement curvature. Therefore, the occlusal seat in this invention can better fit different patients; the upper occlusal pad is a soft pad that contacts the patient's upper central incisors and lateral incisors; the first slide and the second slide are used to limit the rotation of the first slide and the second slide, respectively; the first lip plate and the second lip plate are arc-shaped plates that contact the patient's upper left and right lips, respectively, and are located at the corners of the patient's mouth.

[0027] Specifically, the lower training component includes a lower occlusal seat 461, a lower occlusal pad 462, a third slide groove 463, a fourth slide groove 464, a third slide block 465, a fourth slide block 466, a third lip plate 467, a fourth lip plate 468, a left rotation device 469, and a right rotation device 460; the lower occlusal pad is fixedly mounted on the lower occlusal seat; the lower occlusal seat is fixedly connected to a third connecting rod and a fourth connecting rod at both ends; the third slide groove and the fourth slide groove are fixedly mounted on the third connecting rod and the fourth connecting rod, respectively; the third slide block and the fourth slide block are slidably mounted on the third connecting rod and the fourth connecting rod, respectively; the third slide block and the fourth slide block are slidably mounted on the third connecting rod and the fourth connecting rod, respectively. The third and fourth slides are provided on the third and fourth slides; the third and fourth lip plates are respectively fixedly provided on the inner sides of the third and fourth slides; the left and right rotation devices are respectively provided on the left and right wearing seats; the structure of the right wearing seat is the same as that of the left wearing seat; the lower occlusal seat is arc-shaped from a top view and is relatively short in width, corresponding to the patient's lower central and lateral incisors; the lower occlusal pad is a soft pad that contacts the patient's lower central and lateral incisors; the third and fourth slides are used to restrict the rotation of the third and fourth slides respectively; the third and fourth lip plates are arc-shaped plates that contact the patient's lower left and right lips respectively and are located at the corners of the patient's mouth; When the impedance training mechanism is not connected, patients can open the left corner of their mouth by moving the first and third slides, or open the right corner of their mouth by moving the second and fourth slides, to perform mouth-opening exercises and stimulate the lip muscles. This is suitable for patients in the early stage of postoperative recovery, when their muscles are weak and they cannot perform impedance training. Therefore, manual non-impedance training is required.

[0028] Specifically, the left-side rotating device includes a first rotating wheel 4691, a first gear 4692, and a second gear 4693; the first rotating wheel is rotatably mounted on the left-side wearing seat; the first gear is rotatably mounted on the left-side wearing seat and coaxially arranged with the first rotating wheel; the second gear is rotatably mounted on the left-side wearing seat and coaxially arranged with one end of the third connecting rod; the second gear meshes with the first gear and has a larger diameter than the first gear; when the impedance training mechanism is not connected, the patient rotates the first rotating wheel, which drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the third connecting rod to rotate; since the right-side rotating device has the same structure, the left-side rotating device can be operated simultaneously. The rotating device and the right-side rotating device can rotate the third and fourth links, which in turn drive the lower occlusal seat to rotate, allowing the patient to practice opening their mouth and stimulating the temporomandibular muscles. The diameter of the first gear is smaller than that of the second gear, so the rotation angle of the third and fourth links can be more precisely controlled during operation, that is, the mouth opening angle can be controlled. Compared with motor control, manual operation allows the patient to quickly adjust according to their own feelings, avoiding the delay caused by motor control that results in an excessively large mouth opening angle or an excessively long mouth opening time. At the same time, the manual control method has a simpler structure, lower cost, and does not require the configuration of batteries and other components, further reducing weight and size, making it easier for patients to carry.

[0029] Specifically, the impedance training mechanism includes a base 51, an occlusal impedance component 52, a left lip impedance component 53, and a right lip impedance component 54. The occlusal impedance component is mounted on the base and can be detachably connected to the upper and lower training components. The left lip impedance component is located on the left side of the base and can be detachably connected to the upper and lower training components. The right lip impedance component is located on the right side of the base and can be detachably connected to the upper and lower training components. The right lip impedance component has the same structure as the left lip impedance component. The base is placed on a table and is relatively heavy, which can prevent displacement from affecting the impedance training. The occlusal impedance component, in conjunction with the portable training mechanism, can realize occlusal impedance training. The left and right lip impedance components, in conjunction with the portable training mechanism, can realize lip-puckering impedance training.

[0030] Specifically, the occlusal impedance assembly includes an upper connecting seat 521, an upper connecting groove 522, a fifth sliding groove 523, an occlusal impedance slider 524, an occlusal impedance sliding plate 525, a lower connecting seat 526, a lower connecting groove 527, and an occlusal adjustment device 528. The upper connecting seat is fixedly mounted on the base. The upper connecting groove is fixedly mounted on the upper occlusal seat and can be magnetically connected to the upper connecting seat. The fifth sliding groove is fixedly mounted on the base. The occlusal impedance slider is slidably mounted on the fifth sliding groove. The occlusal impedance sliding plate is slidably mounted inside the occlusal impedance slider. The lower connecting seat is rotatably mounted on one side of the occlusal impedance sliding plate. The lower connecting groove is fixedly mounted on the lower occlusal seat and can be magnetically connected to the lower connecting seat. The occlusal adjustment device is mounted on the base and connected to the occlusal impedance slider. The magnetic connection uses a strong magnet, such as a neodymium magnet, so that the portable training mechanism and the occlusal impedance assembly will not detach during occlusal training.

[0031] Specifically, the engagement adjustment device includes a second rotating wheel 5281, a third gear 5282, multiple fourth gears 5283, multiple threaded posts 5284, and multiple first springs 5285; the second rotating wheel is rotatably mounted on the top of the base; the third gear is rotatably mounted on the base and coaxially arranged with the second rotating wheel; one end of each of the multiple first springs is fixedly mounted at the four corners of the engagement resistance slider; the multiple threaded posts are slidably mounted on the base and fixedly connected to the other end of each of the multiple first springs; the multiple fourth gears are rotatably mounted on the base and mesh with the third gear; the multiple fourth gears are respectively sleeved and meshed with the multiple threaded posts; the fourth gears and threaded posts are threadedly engaged; the bottom of the threaded posts has a vertically oriented... The groove allows it to slide vertically on the base only, not rotate; the first spring is a compression spring; rotating the second wheel drives the third gear to rotate, which in turn drives multiple fourth gears to rotate. The fourth gears, through threads, cause multiple threaded columns to move vertically, compressing multiple first springs and increasing the preload of the multiple first springs, thus increasing the resistance during occlusal training; during occlusal resistance training, the patient drives the lower occlusal seat, the third link, and the fourth link to rotate together, which in turn drives the lower connecting seat to rotate, causing the occlusal resistance slide plate to move upward and retract into the occlusal resistance slider, and causing the occlusal resistance slider to move upward in the fifth groove, compressing multiple first springs. The multiple first springs then apply a counter-force, providing resistance.

[0032] Specifically, the left lip impedance assembly includes a sixth slide groove 531, a left impedance slider 532, a left impedance connector 533, a first left connector 534, a second left connector 535, a left pin 536, a left adjustment device 537, and a limiting rod 538. The sixth slide groove is fixedly disposed on the left side of the base. The left impedance slider is slidably disposed on the sixth slide groove. The left impedance connector is slidably disposed on the left impedance slider. The first left connector and the second left connector are respectively fixedly disposed on the first slide and the third slide. The left impedance connector is connected to the first left connector and the second left connector via a left pin. The left adjustment device is disposed on the base and connected to the left impedance slider. The limiting rod is threaded and rotatably disposed at the bottom of the base. The left pin passes through the first left connector and the second left connector. The connecting seat and the left impedance connecting seat can connect the first left connecting seat, the second left connecting seat, and the left impedance connecting seat. The left impedance connecting seat can slide completely into the left impedance slider. During occlusion training, the left pin needs to be removed and the left impedance connecting seat pushed into the left impedance slider to avoid interference. The same applies to the right side. During lip impedance training, the patient needs to close their mouth. To prevent the occlusion impedance slider from moving and opening the patient's mouth, the limiting rod needs to be rotated to push the occlusion impedance slider to the top of the fifth groove, so that the patient's mouth remains closed and does not need to resist the impedance generated by the occlusion impedance slider. During occlusion training, the patient needs to open and close their mouth. Therefore, the limiting rod needs to be rotated and removed. At this time, the occlusion impedance slider can slide to provide occlusion impedance and assist the patient in occlusion training.

[0033] Specifically, the left-side adjustment device includes a left-side push rod 5371, a third rotating wheel 5372, a seventh sliding groove 5373, a left-side adjustment plate 5374, and a left-side spring 5375; the seventh sliding groove is fixedly mounted on the left-side push rod; the third rotating wheel is rotatably mounted on the left side of the base; the left-side push rod is slidably mounted on the base and passes through the third rotating wheel; the left-side adjustment plate is slidably mounted on the seventh sliding groove and its outer side is threadedly engaged with the third rotating wheel; the two ends of the left-side spring are respectively fixedly mounted on the left-side push rod and the left-side adjustment plate; the left-side push rod is fixedly connected to the left-side resistance slider; the seventh sliding groove is positioned opposite the left side... The top rod and the left adjustment plate are limited to prevent rotation; the left spring is a compression spring; rotating the third rotating wheel drives the left adjustment plate to move via a thread, adjusting the preload of the left spring, and thus adjusting the resistance during lip-pouting training; when the patient pouts, it will drive the first lip plate and the third lip plate to move on the first and third connecting rods respectively, thereby driving the left impedance connector to move laterally and partially retract into the left impedance slider, and driving the left impedance slider to move laterally, thereby driving the left top rod to move, compressing the left spring. The left spring will apply a reverse thrust, that is, provide resistance, and the same applies to the right side.

[0034] Specifically, the wearing mechanism includes multiple left-side straps 31 and multiple right-side straps 32; the multiple left-side straps are respectively rotatably disposed on the rear and upper sides of the left-side wearing seat; the multiple right-side straps are respectively rotatably disposed on the rear and upper sides of the right-side wearing seat; the multiple left-side straps and the multiple right-side straps are connected by a snap fastener; compared with the prior art, the present invention adds an upper strap, making the wearing more secure.
