Description

Technical Field

[0001] This invention relates to the field of oral and maxillofacial muscle strength rehabilitation training technology, specifically to a human oral and maxillofacial muscle strength rehabilitation training device. Background Technology

[0002] Oral and maxillofacial surgery is a discipline that focuses on surgical treatment and studies the prevention and treatment of diseases of the oral organs, facial soft tissues, maxillofacial bones, temporomandibular joint, salivary glands, and certain related diseases of the neck. The human oral and maxillofacial region is an important organ for eating, expressing facial expressions, and speaking.

[0003] After facial nerve damage, patients are prone to insufficient strength in the maxillofacial muscles, which can lead to symptoms such as facial paralysis or slurred speech. Therefore, rehabilitation training of the maxillofacial muscles is necessary. Currently used maxillofacial muscle rehabilitation training devices generally expand by rotating a screw, thereby using the expansion to rehabilitate the patient's maxillofacial muscles. When the patient experiences discomfort during rehabilitation training, the rehabilitation device cannot be removed immediately. It can only be removed from the patient's mouth after the expansion area is slowly adjusted by using the screw. Summary of the Invention

[0004] The purpose of this invention is to provide a human oral and maxillofacial muscle strength rehabilitation training device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] The expansion component includes a fixed rod, which is fixedly connected to the inner wall of the circular hole rod. A movable frame is slidably connected to the surface of the fixed rod. A base is fixedly connected to the surface of the movable frame. A telescopic rod is fixedly connected to the end of the base away from the movable frame.

The end of the triangular frame is sleeved on the surface of the extension rod.

[0008] Furthermore, there are two sliding hole brackets, which are symmetrically arranged around the limiting frame and located at the upper and lower ends of the limiting frame. The end of the round hole rod passes through the limiting frame and extends to the outer end of the limiting frame.

[0009] Furthermore, the fixed rod is located inside the limiting frame, the end of the telescopic rod away from the base extends to the outer end of the sliding hole frame through the sliding hole frame, there are two bending rods, the two bending rods are symmetrically arranged with the fixed rod as the center, the arc plate is located at the end of the bending rods that are close to each other, and the center of the tripod is hinged.

[0010] Furthermore, there are two bases, which are symmetrically arranged around the movable frame and located at the upper and lower ends of the movable frame. The inner wall of the slide frame is slidably connected to the surface of the slide plate.

[0011] Furthermore, the driving component includes a round rod, the end of which is fixedly connected to the end of a fixed rod, an insertion hole is provided at the top of the round rod, a force-bearing frame is slidably connected to the surface of the round rod, a positioning frame is fixedly connected to the surface of the force-bearing frame, a spring rod is fixedly connected to the surface of the positioning frame, and a push rod is fixedly connected to the end of the spring rod away from the force-bearing frame.

[0012] The end of the push rod away from the spring rod is fixedly connected to the base. A base frame is fixedly connected to the lower surface of the limiting frame. A vertical rod is fixedly connected to the bottom of the base frame and the positioning frame respectively. A rubber pad is fixedly connected to the surface of the vertical rod. A socket frame is fixedly connected to the surface of the positioning frame. A plug rod is slidably connected to the inner wall of the socket frame.

[0013] Furthermore, the end of the push rod away from the spring rod passes through the limiting frame and extends into the interior of the limiting frame, the lower surface of the insertion rod is adapted to the inner wall of the insertion hole, and the insertion hole frame is located at the end of the positioning frame away from the spring rod.

[0014] Furthermore, the extrusion component includes a limiting rod, which is fixedly connected to the inner wall of the tripod. An inclined plate is hinged to the surface of the limiting rod, and a center plate is hinged to the end of the inclined plate away from the limiting rod. A spring rod is fixedly connected to the surface of the center plate, and the spring rod is fixedly connected to the positioning frame through a connecting rod.

[0015] Furthermore, the limiting rod is located at the end of the tripod away from the limiting frame, and two limiting rods are provided on the inner wall of the tripod. The surfaces of the two limiting rods are fixedly connected with spring pieces, and the surface of the center plate is provided with two inclined plates, with the ends of the two inclined plates away from the center plate being arranged to be far apart from each other.

[0016] The present invention has the following beneficial effects:

[0017] When a patient needs oral and maxillofacial muscle rehabilitation training, the arc-shaped plate is placed in the patient's mouth. At this time, the protective pad on the surface of the arc-shaped plate will come into contact with the patient's teeth. The part in contact with the patient is set in an arc shape, which can provide large-area support in the patient's oral cavity, avoiding the discomfort caused by small-area support. When the moving frame slides on the surface of the fixed rod, the moving frame pushes the bending rod to a certain position through the telescopic rod. When the bending rod moves, it pushes the tripod through the connection of the extension rod to cause the tripod to deform, so that the tripod can push the bending rod to the end away from the limiting frame. The movement of the bending rod pushes the arc-shaped plate to expand the patient's oral cavity, thereby performing oral and maxillofacial muscle rehabilitation training for the patient.

[0018] This invention uses a vertical rod to push a force-bearing frame to slide on the surface of a round rod. When the force-bearing frame moves, the connection between the positioning frame and the spring rod pushes a push rod to move inwards towards the limiting frame. The push rod, in turn, pushes a movable frame on the surface of a fixed rod via a base. This movable frame then pushes a curved rod to perform oral and maxillofacial muscle rehabilitation training on the patient. The force-bearing frame can drive the positioning frame to slide rapidly on the surface of the round rod, allowing the curved rod to open and close quickly. It can be quickly removed if the patient experiences discomfort during training. During training, the force-bearing frame can be fixed to the surface of the round rod by inserting a rod into a socket. The patient can then perform rehabilitation training on the oral and maxillofacial muscles through their own biting. When the patient bites down on the arc plate, the arc plate is pressured, pushing the curved rod towards the surface of the limiting frame. Simultaneously, the curved rod pushes the movable frame to slide on the surface of the fixed rod via a telescopic rod, without compressing the spring rod through the push rod. This allows the patient to perform rehabilitation training on their oral and maxillofacial muscles independently through biting.

[0019] When the positioning frame of this invention moves, it pushes the elastic rod to move through the connecting rod. When the elastic rod moves, it pushes the end of the inclined plate to expand outward through the central plate. When the inclined plate expands, the tripod expands outward. The compression of the inclined plate reduces the compression force of the tripod when it expands, so that the patient can more easily push the bending rod to start the expansion through the positioning frame, thus improving the convenience of use.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-6As shown, this invention is a rehabilitation training device for the maxillofacial muscles, including a limiting frame 1. A sliding hole frame 2 is connected to the surface of the limiting frame 1. A round hole rod 3 is fixedly connected to the end of the limiting frame 1. Expansion components 4 are provided at the upper and lower ends of the limiting frame 1. When a patient needs to perform maxillofacial muscle rehabilitation training, an arc-shaped plate 15 is placed in the patient's mouth. At this time, the protective pad 16 on the surface of the arc-shaped plate 15 will contact the patient's teeth. The part in contact with the patient is designed in an arc shape, which allows for large-area support within the patient's oral cavity, avoiding the need for small-area support. When the movable frame 10 slides on the surface of the fixed rod 17, causing discomfort, the movable frame 10 pushes the bent rod 14 to a certain position via the telescopic rod 12. As the bent rod 14 moves, it connects to the tripod 19 via the extension rod 22, causing the tripod 19 to deform. This allows the tripod 19 to push the bent rod 14 away from the limiting frame 1. The movement of the bent rod 14 pushes the arc plate 15 to expand the patient's oral cavity, thereby providing rehabilitation training for the patient's oral and maxillofacial muscles. The surface of the limiting frame 1 is provided with a compression component 6, and the end of the limiting frame 1 is provided with a driving component 5.

[0032] The expansion component 4 includes a fixed rod 17, which is fixedly connected to the inner wall of the circular hole rod 3. A movable frame 10 is slidably connected to the surface of the fixed rod 17. A base 11 is fixedly connected to the surface of the movable frame 10. A telescopic rod 12 is fixedly connected to the end of the base 11 away from the movable frame 10. A slant frame 13 is fixedly connected to the end of the telescopic rod 12 away from the base 11. A curved rod 14 is sleeved on the end of the slant frame 13 away from the telescopic rod 12. An arc plate 15 is fixedly connected to the end of the curved rod 14 away from the slant frame 13. A protective pad 16 is fixedly connected to the surface of the arc plate 15. A slide frame 20 is fixedly connected to the surface of the movable frame 10. A sliding plate 21 is fixedly connected to the inner wall of the limiting frame 1. An extension rod 22 is fixedly connected to the surface of the curved rod 14. A triangular frame 19 is sleeved on the surface of the limiting frame 1. The end of the triangular frame 19 is sleeved on the surface of the extension rod 22.

[0033] There are two sliding hole brackets 2. The two sliding hole brackets 2 are symmetrically arranged with the limiting bracket 1 as the center, and the two sliding hole brackets 2 are located at the upper and lower ends of the limiting bracket 1. The end of the round hole rod 3 passes through the limiting bracket 1 and extends to the outer end of the limiting bracket 1.

[0034] The fixed rod 17 is located inside the limiting frame 1. The end of the telescopic rod 12 away from the base 11 extends to the outer end of the sliding frame 2 through the sliding frame 2. There are two bending rods 14, which are symmetrically arranged with the fixed rod 17 as the center. The arc plate 15 is located at the end of the bending rods 14 that are close to each other. The center of the tripod 19 is hinged.

[0035] There are two bases 11, which are symmetrically arranged around the movable frame 10 and located at the upper and lower ends of the movable frame 10. The inner wall of the slide frame 20 is slidably connected to the surface of the slide plate 21.

[0036] The driving component 5 includes a round rod 30, the end of which is fixedly connected to the end of a fixed rod 17. A hole 31 is provided at the top of the round rod 30. A force-bearing frame 37 is slidably connected to the surface of the round rod 30, and a positioning frame 35 is fixedly connected to the surface of the force-bearing frame 37. In this invention, the force-bearing frame 37 is pushed to slide on the surface of the round rod 30 by a vertical rod 38. When the force-bearing frame 37 moves, the connection between the positioning frame 35 and the spring rod 32 pushes the push rod 39 to move into the limiting frame 1. When the push rod 39 moves, it pushes the moving frame 10 to move on the surface of the fixed rod 17 via the base 11. This allows the moving frame 10 to push the bending rod 14 to perform oral and maxillofacial muscle rehabilitation training on the patient. The force-bearing frame 37 can drive the positioning frame 35 to slide rapidly on the surface of the round rod 30, thereby causing the bending rod 14 to... It can be opened and closed quickly, and can be quickly removed when the patient experiences discomfort during training. During training, the force frame 37 can be fixed to the surface of the round rod 30 by inserting the rod 34 and the hole 31. At this time, the patient can perform rehabilitation training of the oral and maxillofacial muscles through his own biting. When the patient bites down on the arc plate 15, the arc plate 15 is pressured and pushes the curved rod 14 to move towards the surface of the limiting frame 1. At the same time, the curved rod 14 pushes the moving frame 10 to slide on the surface of the fixed rod 17 through the telescopic rod 12, and does not compress the spring rod 32 through the push rod 39 to retract, so that the patient can perform rehabilitation training of the oral and maxillofacial muscles by biting. The surface of the positioning frame 35 is fixedly connected to the spring rod 32, and the end of the spring rod 32 away from the force frame 37 is fixedly connected to the push rod 39.

[0037] The end of the push rod 39 away from the spring rod 32 is fixedly connected to the base 11. The lower surface of the limiting frame 1 is fixedly connected to the base frame 40. The bottom of the base frame 40 and the positioning frame 35 are respectively fixedly connected to the bottom of the vertical rod 38. The surface of the vertical rod 38 is fixedly connected to the rubber pad 36. The surface of the positioning frame 35 is fixedly connected to the insertion frame 33. The inner wall of the insertion frame 33 is slidably connected to the insertion rod 34.

[0038] The end of the push rod 39 away from the spring rod 32 passes through the limiting frame 1 and extends into the interior of the limiting frame 1. The lower surface of the insertion rod 34 is adapted to the inner wall of the insertion hole 31. The insertion hole frame 33 is located at the end of the positioning frame 35 away from the spring rod 32.

[0039] The compression component 6 includes a limiting rod 53, which is fixedly connected to the inner wall of the tripod 19. An inclined plate 51 is hinged to the surface of the limiting rod 53. A center plate 54 is hinged to the end of the inclined plate 51 away from the limiting rod 53. An elastic rod 56 is fixedly connected to the surface of the center plate 54. When the positioning frame 35 moves, it pushes the elastic rod 56 to move through the connecting rod 55. When the elastic rod 56 moves, it pushes the end of the inclined plate 51 to expand outward through the center plate 54. When the inclined plate 51 expands, it moves the tripod 19 to expand outward. The compression of the inclined plate 51 reduces the compression force of the tripod 19 during expansion, making it easier for the patient to push the bending rod 14 to start expansion through the positioning frame 35, thus improving the convenience of use. The elastic rod 56 is fixedly connected to the positioning frame 35 through the connecting rod 55.

[0040] The limiting rod 53 is located at the end of the tripod 19 away from the limiting frame 1. Two limiting rods 53 are provided on the inner wall of the tripod 19. Spring pieces 52 are fixedly connected to the surfaces of the two limiting rods 53. Two inclined plates 51 are provided on the surface of the center plate 54. The ends of the two inclined plates 51 away from the center plate 54 are set to be far apart from each other.

[0041] When in use, the arc-shaped plate 15 is placed in the patient's mouth for oral and maxillofacial muscle rehabilitation training. At this time, the protective pad 16 on the surface of the arc-shaped plate 15 will contact the patient's teeth. The contact area is arc-shaped, allowing for large-area support within the patient's oral cavity, avoiding discomfort caused by small-area support. When the movable frame 10 slides on the surface of the fixed rod 17, the movable frame 10 pushes the bent rod 14 to a certain position via the telescopic rod 12. During movement, the bent rod 14, through the connection between the extension rod 22 and the tripod 19, causes the tripod 19 to deform, thereby... This allows the tripod 19 to push the curved rod 14 to move away from the limiting frame 1. The movement of the curved rod 14 pushes the arc plate 15 to expand the patient's oral cavity, thereby performing rehabilitation training for the patient's oral and maxillofacial muscles. The vertical rod 38 pushes the force frame 37 to slide on the surface of the round rod 30. When the force frame 37 moves, the connection between the positioning frame 35 and the spring rod 32 pushes the push rod 39 to move into the limiting frame 1. When the push rod 39 moves, it pushes the moving frame 10 to move on the surface of the fixed rod 17 through the base 11. Thus, the moving frame 10 pushes the curved rod 14 to perform oral and maxillofacial rehabilitation training for the patient. For muscle rehabilitation training, the force-bearing frame 37 can drive the positioning frame 35 to slide quickly on the surface of the round rod 30, thereby allowing the bending rod 14 to open and close quickly. It can be quickly removed when the patient experiences discomfort during training. During training, the force-bearing frame 37 can be fixed to the surface of the round rod 30 by inserting the insertion rod 34 into the insertion hole 31. At this time, the patient can perform rehabilitation training of the oral and maxillofacial muscles through their own biting. When the patient bites down on the arc plate 15, the arc plate 15 is pressured, pushing the bending rod 14 towards the surface of the limiting frame 1. Simultaneously, the bending rod 14 pushes the moving frame 1 through the telescopic rod 12. The 0 slides on the surface of the fixed rod 17 and does not compress the spring rod 32 through the push rod 39 to retract, allowing the patient to perform oral and maxillofacial muscle rehabilitation training by biting. When the positioning frame 35 moves, it pushes the spring rod 56 to move through the connecting rod 55. When the spring rod 56 moves, it pushes the end of the inclined plate 51 to expand outward through the center plate 54. When the inclined plate 51 expands, it moves the tripod 19 to expand outward. The compression of the inclined plate 51 reduces the compression force of the tripod 19 during expansion, making it easier for the patient to push the curved rod 14 to start expansion through the positioning frame 35, thus improving the convenience of use.
