Abstract
Description
Technical Field
[0001] This invention specifically relates to an oral occlusion exercise device. Background Technology
[0002] The oral and maxillofacial region is a common site for tumors. Clinically, most oral and maxillofacial tumors are benign. They grow slowly and are often discovered accidentally. Most tumors are well-defined, without tenderness or nerve invasion symptoms. For diagnosed benign oral and maxillofacial tumors, surgical resection or radiotherapy is often used. Postoperatively, these tumors can easily cause damage to the facial muscles, temporomandibular joint, and oral masticatory muscles, resulting in functional impairments such as limited mouth opening, weak biting, and stiff joint movement. These impairments severely affect patients' daily physiological functions such as eating and speaking. Therefore, oral occlusion training is necessary for patients.
[0003] For example, Chinese patent CN223874351U discloses an oral occlusion exerciser for patients with head and neck tumors after radiotherapy. This device allows for progressive mouth-opening exercises based on the distance it is inserted into the mouth, achieving a gradual training effect. The protruding ridges prevent slippage during each stage of occlusion, limiting tooth positioning and thus enhancing mouth-opening ability. The elasticity of the elastic balls further strengthens the masticatory muscles of the jaw during occlusion exercises, promoting muscle recovery.
[0004] However, current bite training devices are mainly divided into two categories: fixed-intensity and manually adjustable. Fixed-intensity devices provide a single, constant training intensity, which cannot adapt to the different rehabilitation tolerance levels of different patients. Adjustable-intensity devices mostly rely on manual adjustment by medical staff or patients to change the intensity, which is cumbersome and cannot match the patient's real-time training status. Patients require continuous and gradual intensity stimulation during rehabilitation; manual adjustment cannot match the initial mild muscle stimulation with the gradual increase in intensity later, reducing the overall postoperative rehabilitation effect. Therefore, this paper proposes an oral bite training device to solve the above problems. Summary of the Invention
[0005] Therefore, it is necessary to address the problem that existing oral occlusion exercise devices after maxillofacial tumor surgery are divided into two types: fixed and adjustable. The exercise devices with fixed training intensity have poor exercise effects and cannot be used by patients at various stages of rehabilitation. The exercise devices with adjustable training intensity mostly require manual adjustment and cannot automatically and gradually increase the exercise intensity during the training process, thus leading to a decline in their rehabilitation effect. Therefore, it is necessary to provide an oral occlusion exercise device.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an oral occlusion exercise device, comprising: A housing, on which a first training frame is fixedly mounted; The second training rack has one end hinged to the first training rack, and both the first training rack and the second training rack have dental pads at their ends. A support column is installed on the second training frame, and a torsion spring is sleeved on the support column, with one end of the torsion spring connected to the second training frame; A fastening disc, rotatably mounted on the support column and connected to the other end of the torsion spring, is capable of moving with the first training frame; and A transmission unit, disposed within the housing, drives the fastening disc to rotate at a fixed angle after the second training frame has rotated multiple times, thereby torsioning the torsion spring.
[0007] In one embodiment, both the first training frame and the second training frame are provided with mounting rods, and the dental pad is detachably fitted onto the mounting rods.
[0008] In one embodiment, the transmission unit includes: A horizontal sliding bar is slidably mounted on the first training frame, and a first elastic element is provided between the bar and the first training frame; A toggle mechanism, mounted on the second training frame and connected to the transverse lever, drives the transverse lever to slide once after the second training frame rotates multiple times within the housing; and A one-way drive mechanism is disposed on the first training frame and connected to the transverse rod and the fastening plate to convert the sliding of the transverse rod into driving the fastening plate to rotate and lock.
[0009] In one embodiment, the actuating mechanism includes: An active ratchet disc is mounted on the second training frame; A mounting post is rotatably and slidably mounted on the first training frame along its axis. One end of the mounting post is provided with a driven ratchet disc, which meshes with the driving ratchet disc. The other end of the mounting post is provided with a ratchet wheel. A second elastic element is disposed between the ratchet and the first training frame; A pawl, slidably mounted on the first training frame by a spring, and engaged with the ratchet; and A linkage component is disposed on the driven ratchet disk and connected to the transverse lever to drive the transverse lever to slide when the driven ratchet disk rotates one revolution.
[0010] In one embodiment, the linkage component includes: A lever, disposed at the end of the transverse lever; and A wedge-shaped block is disposed on one side of the driven ratchet disc and is capable of abutting against the lever to push the transverse lever to slide.
[0011] In one embodiment, the unidirectional drive mechanism includes: The mounting frame is fixedly mounted on the first training frame and has a sliding block, which is connected to the transverse rod through an acceleration component; A guide post is slidably mounted on the slide block and is provided with a first baffle. A third elastic element is provided between the first baffle and the slide block. Multiple sets of straight tracks are provided and arranged circumferentially around the fastening disc, with the end of the guide post slidably engaged at the end of the straight track; and Multiple sets of inclined tracks are provided and arranged circumferentially around the fastening disc. One end of each inclined track is connected to one of the straight tracks via a first limiting inclined platform, and the other end is connected to the middle section of an adjacent straight track via a second limiting inclined platform.
[0012] In one embodiment, the speed-up component includes: The first rack is disposed at the end of the transverse rod; The second rack is connected to the slide block and faces the same direction as the first rack. The first gear is rotatably mounted on the first training frame and meshes with the first rack; and The second gear is arranged coaxially with the first gear and meshes with the second rack. The diameter of the second gear is larger than that of the first gear.
[0013] In one embodiment, the end of the second rack slides through a connecting frame on one side of the slide block, and a second baffle is provided on the second rack. A fourth elastic element is provided between the second baffle and the slide block, and a first push rod is also provided on the slide block.
[0014] In one embodiment, the housing is further provided with a reset assembly connected to the guide post, the reset assembly comprising: A slanted frame is arranged on the guide post, and one end of the frame is connected to a straight frame, the width of which is greater than that of the slanted frame. The second push rod is slidably mounted on the housing and is provided with a third baffle. The end of the second push rod is provided with a drive post, which is located between the straight frame and the inclined frame. A stop bracket is disposed inside the housing, and a fifth elastic element is provided between the stop bracket and the third baffle. The first limiting block is fixedly installed inside the first training frame; and The second limiting block is disposed on the fastening plate and can abut against the first limiting block.
[0015] In one embodiment, the housing is further provided with an indicator frame, an indicator wheel is rotatably provided inside the housing, a third gear is provided on one side of the fastening disc, and a fourth gear is provided on one side of the indicator wheel that meshes with the third gear.
[0016] Compared with the prior art, the present invention has at least the following advantages: When using this device, the patient can bite down on the dental pads on the first and second training frames. This causes the second training frame to rotate at a certain angle within the housing along its hinge point with the first training frame. The fastening plate follows the movement of the first training frame, allowing the second training frame to rotate and move one end of the torsion spring, which in turn twists the torsion spring in conjunction with the fastening plate. The torsion spring applies resistance to the patient's biting motion, achieving a good training effect. Simultaneously, after multiple bites, the patient can control the fastening plate to rotate at a fixed angle under the action of the transmission unit, further twisting the torsion spring. This requires greater force for subsequent bites, allowing for a gradual increase in training intensity without manual adjustment. This aligns with the medical principle of gradual rehabilitation, enhancing the postoperative rehabilitation of the oral muscles and joints, and facilitating the rapid recovery of the patient's maxillofacial function.

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.
[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0023] Example: Please see Figures 1 to 4 The present invention provides an oral occlusion exerciser, comprising a housing 1, a first training frame 2 fixedly mounted on the housing 1, and a second training frame 3. One end of the second training frame 3 is hinged to the first training frame 2, and both the first training frame 2 and the second training frame 3 are provided with dental pads 22. A support column 32 is provided on the second training frame 3, and a torsion spring 81 is sleeved on the support column 32. One end of the torsion spring 81 is connected to the second training frame 3. A fastening plate 8 is rotatably sleeved on the support column 32, and the fastening plate 8 is connected to the other end of the torsion spring 81. The fastening plate 8 can move with the first training frame 2.
[0024] Preferably, both the first training frame 2 and the second training frame 3 are provided with mounting rods 21. The mouth pad 22 is detachably fitted onto the mounting rods 21, which facilitates the replacement and cleaning of the mouth pad 22. The mouth pad 22 can be placed in the mouth, and the second training frame 3 can be rotated on the housing 1 by biting the mouth pad 22. The movement of the second training frame 3 is resisted by the torsion spring 81, thereby realizing the exercise of oral biting.
[0025] Please see Figures 3 to 6 In this embodiment, a transmission unit is provided inside the housing 1. After the second training frame 3 rotates multiple times, the transmission unit drives the fastening plate 8 to rotate at a fixed angle to torsion the torsion spring 81. The transmission unit includes a slidable horizontal rod 5 mounted on the first training frame 2. A first elastic element 58 is provided between the horizontal rod 5 and the first training frame 2. The second training frame 3 is provided with a toggle mechanism connected to the horizontal rod 5. After the second training frame 3 rotates multiple times inside the housing 1, the toggle mechanism drives the horizontal rod 5 to slide once.
[0026] The actuation mechanism includes an active ratchet 31 mounted on the second training frame 3. A mounting post 4 is rotatably and slidably inserted on the first training frame 2. A driven ratchet 41 is mounted at one end of the mounting post 4, and the driven ratchet 41 meshes with the active ratchet 31. A ratchet 42 is mounted at the other end of the mounting post 4. A second elastic element 43 is provided between the ratchet 42 and the first training frame 2. A pawl 44 is slidably mounted on the first training frame 2 by a spring and is engaged with the ratchet 42. A linkage assembly connected to the transverse lever 5 is provided on the driven ratchet 41. The linkage assembly drives the transverse lever 5 to slide when the driven ratchet 41 rotates one revolution. The linkage assembly includes a lever 51 located at the end of the transverse lever 5. A wedge block 45 is provided on one side of the driven ratchet 41. The wedge block 45 can abut against the lever 51 to push the transverse lever 5 to slide.
[0027] The rotation of the mounting post 4 can be unidirectionally locked by the cooperation of the pawl 44 and the ratchet 42, thus preventing the driven ratchet 41 from driving the active ratchet 31 to rotate when it reverses. During the biting training, the active ratchet 31 on the second training frame 3 rotates on the first training frame 2, which drives the driven ratchet 41 and the mounting post 4 to rotate. Under the action of the second elastic element 43, the driven ratchet 41 is always locked on the active ratchet 31. Each biting can control the driven ratchet 41 to rotate a certain angle. Multiple biting can control the driven ratchet 41 to rotate one revolution on the first training frame 2. After the driven ratchet 41 rotates one revolution, the transverse sliding rod 5 can be pushed laterally a certain distance by the abutment of the wedge block 45 and the lever 51.
[0028] Please see Figure 6 In this embodiment, the transmission unit further includes a one-way drive mechanism disposed on the first training frame 2 and connected to the transverse rod 5 and the fastening plate 8. The one-way drive mechanism converts the sliding of the transverse rod 5 into driving the fastening plate 8 to rotate and lock. The one-way drive mechanism includes a mounting frame 23 fixedly disposed on the first training frame 2. A slide block 6 is slidably disposed on the mounting frame 23. The slide block 6 is connected to the transverse rod 5 through an acceleration component. The acceleration component includes a first rack 52 disposed at the end of the transverse rod 5. A second rack 55 is disposed on the slide block 6. The second rack 55 and the first rack 52 face the same direction. A first gear 53 is disposed on the first training frame 2. The first gear 53 meshes with the first rack 52. A second gear 54 is coaxially arranged on the first gear 53. The second gear 54 meshes with the second rack 55. The diameter of the second gear 54 is larger than that of the first gear 53.
[0029] During the sliding process, the transverse rod 5 can compress the first elastic element 58, thereby controlling the transverse rod 5 to return to its original position through the first elastic element 58. After sliding a certain distance, the transverse rod 5 can drive the second gear 54 to rotate through the cooperation of the first rack 52 and the first gear 53, thereby controlling the second rack 55 to move in the same direction as the first rack 52 and increase the distance. This structure can amplify the movement of the transverse rod 5 and reduce the space required for the transverse rod 5 to drive the sliding of a specified distance.
[0030] Please see Figure 3 , Figures 6 to 9 In this embodiment, the unidirectional drive mechanism further includes a guide post 63 that is slidably disposed on the slide block 6. A first baffle 64 is disposed on the guide post 63. A third elastic element 65 is disposed between the first baffle 64 and the slide block 6. Multiple sets of straight tracks 83 and inclined tracks 84 are arranged circumferentially around the fastening plate 8. The end of the guide post 63 is slidably locked at the end of the straight track 83. One end of the inclined track 84 is connected to one of the sets of straight tracks 83 through a first limiting inclined platform 85, and is connected to the middle section of an adjacent set of straight tracks 83 through a second limiting inclined platform 86.
[0031] During the sliding process, the second rack 55 can drive the slide block 6 to slide laterally. During the sliding process, the slide block 6 drives the guide post 63 to slide. The guide post 63 can slide into the inclined track 84 through the guidance of the second limiting ramp 86, so as to drive the fastening plate 8 to rotate. When the transverse rod 5 is reset, it can drive the slide block 6 to reset, so that the guide post 63 can slide in the adjacent set of straight tracks 83 through the guidance of the first limiting ramp 85, so as to lock the fastening plate 8. During the rotation of the fastening plate 8, the torsion spring 81 can be twisted, so that the subsequent rotation of the torsion spring 81 requires more force, and one end of the torsion spring 81 is relatively fixed to the first training frame 2, thereby increasing the resistance during each bite, so as to achieve a gradual increase in bite resistance during the exercise process.
[0032] Please see Figure 6 In this embodiment, the end of the second rack 55 slides through the connecting frame 61 on one side of the slide block 6, and a second baffle 56 is provided on the second rack 55. A fourth elastic element 57 is provided between the second baffle 56 and the slide block 6, and a first push rod 62 is also provided on the slide block 6. During the sliding process, the second rack 55 can pull the slide block 6 to slide through the second baffle 56. The fourth elastic element 57 can apply a reverse thrust to the slide block 6 to ensure that the guide post 63 is reset. The slide block 6 can also be directly driven to slide by pressing the first push rod 62 to manually increase the initial training force. This is suitable for patients with large initial force, allowing such patients to directly perform high-intensity biting exercises, avoiding wasting a lot of time on low training resistance, and improving the applicability of the device.
[0033] Please see Figure 3 ,4 In this embodiment, the housing 1 is further provided with a reset assembly connected to the guide post 63. The reset assembly includes an inclined frame 66 arranged on the guide post 63. One end of the inclined frame 66 is connected to a straight frame 67. The width of the straight frame 67 is greater than that of the inclined frame 66. A second push rod 7 is slidably passed through the housing 1. A third baffle 71 is provided on the second push rod 7. A drive post 73 is provided at the end of the second push rod 7. The drive post 73 is located between the straight frame 67 and the inclined frame 66. A stop frame 11 is provided on the inner side of the housing 1. A fifth elastic element 72 is provided between the stop frame 11 and the third baffle 71. A first limiting block 24 is fixedly provided on the inner side of the first training frame 2. A second limiting block 87 is provided on the fastening plate 8. The second limiting block 87 can abut against the first limiting block 24.
[0034] During the sliding process, the slide block 6 provides space for the relative movement of the drive column 73 and the guide column 63 through the straight frame 67, avoiding interference. The width of the straight frame 67 is greater than that of the inclined frame 66, and thus greater than the diameter of the guide column 63, providing space for the up-and-down movement of the guide column 63 when passing the first limiting inclined platform 85 and the second limiting inclined platform 86. After the exercise is completed, the drive column 73 can be slid by pressing the second lever 7, which compresses the fifth elastic element 72. During the sliding process, the drive column 73 can move upward and disengage from the straight track 83 by abutting against the inclined frame 66, releasing the relative locking between the first training frame 2 and the fastening plate 8. The fastening plate 8 can then reverse under the reset of the torsion spring 81 until the second limiting block 87 abuts against the first limiting block 24, causing the fastening plate 8 to reverse to the initial position, thereby controlling the reset of the fastening plate 8 and the torsion spring 81 for the next training.
[0035] Please see Figure 1 , 2 In this embodiment, the housing 1 is further provided with an indicator frame 12, and an indicator wheel 9 is rotatably disposed inside the housing 1. A third gear 82 is disposed on one side of the fastening disc 8, and a fourth gear 91 meshing with the third gear 82 is disposed on one side of the indicator wheel 9. Numbers can be displayed on the indicator wheel 9 to represent the level of exercise resistance. During rotation, the fastening disc 8 drives the indicator wheel 9 to rotate through the meshing of the third gear 82 and the fourth gear 91. The reading of the indicator wheel 9 can be observed through the indicator frame 12, thus providing a convenient and intuitive understanding of the patient's exercise intensity and rehabilitation status.
[0036] Specific usage and beneficial effects of the present invention: When using this device, the patient can bite down on the dental pads 22 on the first training frame 2 and the second training frame 3. This causes the second training frame 3 to rotate at a certain angle within the housing 1 along the hinge point with the first training frame 2. The fastening plate 8 can follow the movement of the first training frame 2. As the second training frame 3 rotates and drives one end of the torsion spring 81 to move, it works in conjunction with the fastening plate 8 to twist the torsion spring 81. The torsion spring 81 applies resistance to the patient's biting action, achieving a good training effect. Simultaneously, after multiple biting actions, the patient can control the fastening plate 8 to rotate at a fixed angle under the action of the transmission unit, twisting the torsion spring 81. This requires greater force for subsequent biting actions, allowing for a gradual increase in training intensity without manual adjustment. This aligns with the medical principle of gradual rehabilitation, enhancing the postoperative rehabilitation effect of the oral masticatory muscles and joints, and helping the patient's maxillofacial function recover quickly.
