Description

Technical Field

[0001] This invention relates to the field of oral examination technology, and in particular to an oral cavity expansion device and system for oral examination. Background Technology

[0002] During oral examinations, patients need to wear an oral expander to open their mouths so that medical staff can observe the oral condition or perform oral treatments. However, when the patient's mouth is open for a long time, the muscles will become stiff and sore. Therefore, in order to alleviate the patient's discomfort and improve the oral examination experience, two pressure points are usually added to the outside of the oral expander. By pressing the sore areas of the face with the pressure points, the patient's discomfort can be reduced.

[0003] In the aforementioned prior art, although the pressure component can alleviate the patient's discomfort, the pressure component only has simple concave and convex points, and can only rely on pressure to achieve the relief effect. Moreover, the pressure area is a whole and cannot be flexibly adjusted. Therefore, the relief effect is limited. Due to the simple structure, it cannot be rotated and adjusted, and it cannot be adapted to different face shapes. Ultimately, it cannot provide high-quality soothing massage for the patient's sore muscles. Summary of the Invention

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] This invention provides an oral cavity expander for oral examination, comprising an upper expander plate 1, a lower expander plate 2, a support frame 3, a bidirectional adjustment mechanism, and two massage components. Each massage component includes multiple massage rollers 4, multiple pressure adjustment units, a flipping mechanism, and multiple rotating massage blocks 5. The bidirectional adjustment mechanism includes a bidirectional drive component 6, an intermediate shaft 7, two threaded rods 8, two threaded blocks 9, and two connecting plates 10. The support frame 3 has two slots 11. The flipping mechanism includes a massage telescopic component 12, a fixing block 13, two guide rods 14, and a massage lifting component 15. The flipping mechanism also includes a U-shaped plate 16, a flipping component 17, and a flipping block 18. The pressure adjustment... The unit includes an adjustment chamber 19, an adjustment plate 20, two limiting mechanisms, two contraction components 21, a damping buffer rod 22, two springs 23, and two spring 23 adjustment mechanisms. The spring 23 adjustment mechanism includes a slide rail 24, a screw mechanism 25, and a threaded plate 26. The limiting mechanism includes a limiting component 28 and a limiting plate 29. The massage assembly also includes an overall rotating component 31, a turntable 32, multiple pump bodies 33, an oil inlet 34, an internal rotating component 35, a rotating auxiliary rod 36, a rotating telescopic component 37, and a kneading block 38. The oral cavity expansion device for oral examination also includes two first rotating blocks 42, multiple second rotating blocks 43, multiple rotating rods 44, and multiple torsion springs 45.

[0029] Please refer to Figures 1 to 5One end of the upper expansion plate 1 and one end of the lower expansion plate 2 are rotatably connected, and the other end of the lower expansion plate 2 is fixedly connected to one side of the support frame 3. The bidirectional adjustment mechanism is disposed on the support frame 3, and two massage components are symmetrically disposed on the bidirectional adjustment mechanism. The flipping mechanism is disposed on the bidirectional adjustment mechanism, and multiple pressure adjustment units and multiple rotating massage blocks 5 are sequentially disposed on the flipping mechanism. Multiple massage wheels 4 are respectively disposed on the corresponding pressure adjustment units. During an oral examination, the upper expansion plate 1 and the lower expansion plate 2 are first used to support the patient's mouth. Then, the bidirectional adjustment mechanism can adjust the two massage components in opposite directions, so that the massage rollers 4 are close to or away from the patient's face. At this time, the pressure adjustment unit is activated to adjust the pressure of multiple massage rollers 4 to a massage intensity that is suitable for the patient. At the same time, the pressure of a single set of massage rollers 4 can also be adjusted to specifically massage the patient's masseter and temporalis muscles. Finally, the multiple massage rollers 4 are adjusted and continuously rolled on the patient's face. After being flipped by the flipping mechanism, the rotating massage block 5 performs local rotational massage. Compared with the traditional single pressure component, this significantly improves the massage quality and enhances the patient's comfort during long oral examinations. In addition, before using the oral expansion device itself, the support frame 3 needs to be fixedly installed on the bed or chair supporting the patient. Then, the patient's neck area is located below the support frame 3, so that the oral cavity can be opened by the upper expansion plate 1 and the lower expansion plate 2.

[0030] Secondly, please refer to Figure 3 The support frame 3 has two slots 11. The bidirectional drive component 6 is disposed on one side of the support frame 3. The intermediate shaft 7 is disposed inside the support frame 3. One end of each of the two threaded rods 8 is symmetrically disposed at one end of the intermediate shaft 7. The other ends of the two threaded rods 8 are respectively connected to the inner wall of the support frame 3 and the output end of the bidirectional drive component 6. Two threaded blocks 9 are respectively adapted to the corresponding threaded rods 8. One end of each of the two connecting plates 10 is fixedly connected to the corresponding threaded blocks 9. The other ends of the two connecting plates 10 are respectively adapted to the corresponding slots 11. The bidirectional drive component 6 is a self-locking motor. After starting, it drives the intermediate shaft 7 to rotate, thereby driving the two threaded rods 8 to rotate. In cooperation with the threaded blocks 9, it drives the two connecting plates 10 to move within the slots 11, thereby driving the massage components on both sides to adjust the massage width, so that the massage rollers 4 move closer to or further away from the patient's face.

[0031] Please also see Figure 2The fixing block 13 is located at the other end of the connecting plate 10. The massage telescopic component 12 and the two guide rods 14 are sequentially arranged inside the fixing block 13. The guide rods 14 are slidably connected to the fixing block 13. The massage lifting component 15 is located at the output end of the massage telescopic component 12. The massage telescopic component 12 is a self-locking electric push rod, and the massage lifting component 15 is an electric slide rail 24. After the massage telescopic component 12 is activated, its output end moves, causing the guide rods 14 to slide within the fixing block 13. Stability is maintained by the action of the guide rods 14, ultimately achieving the purpose of stably adjusting the U-shaped plate 16.

[0032] Additionally, please see Figure 2 The U-shaped plate 16 is located at the output end of the massage lifting component 15, and the flipping component 17 is located on one side of the U-shaped plate 16. The output end of the flipping component 17 is fixedly connected to the flipping block 18, which is located inside the U-shaped plate 16. After the U-shaped plate 16 is extended and retracted, the massage roller 4 can be precisely aligned with the sore area of ​​the patient that needs massage. The flipping component 17 is a self-locking motor. After the massage roller 4 finishes rolling, the flipping component 17 is activated, driving the flipping block 18 to rotate and exchanging the positions of the massage roller 4 and the rotating massage block 5. Thus, the rotating massage block 5 provides targeted rotational massage to the sore local area of ​​the patient, while the massage roller 4 is mainly used for large-area facial rolling massage.

[0033] Then, please see Figures 5 to 7 The adjustment chamber 19 is located on one side of the flip block 18. The adjustment plate 20 is slidably connected to the interior of the adjustment chamber 19. The two limiting mechanisms are symmetrically arranged on the exterior of the adjustment chamber 19. One end of each of the two contraction components 21 and the damping buffer rod 22 is located on the inner bottom wall of the adjustment chamber 19. The output end of the contraction component 21 and the other end of the damping buffer rod 22 are fixedly connected to the adjustment plate 20. The two spring 23 adjustment mechanisms are located on both sides of the adjustment chamber 19. One end of each spring 23 is located on the corresponding side spring 23 adjustment mechanism. The other ends of each spring 23 are movably connected to one end of the adjustment plate 20. The plurality of massage rollers 4 are sequentially arranged on the other end of the adjustment plate 20.

[0034] When the pressure of the massage roller 4 needs to be adjusted, the limiting mechanism first limits the adjustment plate 20 to keep its position unchanged. Then, the spring 23 adjustment mechanism is activated to adjust the contraction position of the spring 23. As the spring 23 is continuously compressed, the pressure of the massage roller 4 on the adjustment plate 20 increases when the limiting mechanism opens. Conversely, as the spring 23 is stretched, the pressure of the massage roller 4 decreases. This allows for the adjustment of the pressure of the massage roller 4, thus adapting to the massage intensity requirements of different patients. It can also be used for massage requirements of different face shapes by excessive stretching. The spring 23 limits the ejection distance of the adjustment plate 20, allowing some of the massage rollers 4 to eject completely while the rest eject only a limited distance, thus adapting to different patients' face shapes. Furthermore, when the adjustment plate 20 is ejected, the limiting mechanism needs to be released. To prevent excessive compression of the spring 23 and subsequent rapid rebound that could harm the patient's face, a damping buffer rod 22 is provided to slow the rebound speed. After the massage ends, the retraction component 21 is activated, causing the adjustment plate 20 to retract into the adjustment chamber 19. The retraction component 21 is an electric push rod.

[0035] Please see again. Figure 7 The slide rail 24 is located on one side of the adjustment chamber 19, and the screw motor 25 is located inside the slide rail 24. The threaded plate 26 is adapted to the output end of the screw motor 25. The adjustment chamber 19 has a groove 27, and the threaded plate 26 passes through the groove 27 and is located inside the adjustment chamber 19. One end of the spring 23 is movably connected to the threaded plate 26. When it is necessary to adjust the tension of the spring 23, the screw motor 25 is started, which drives the threaded plate 26 to slide within the groove 27 and the slide rail 24, thereby compressing or stretching the spring 23. After adjustment, the threaded plate 26 remains stationary. At this time, the limiting mechanism is released, the spring 23 is released, and the adjustment plate 20 and the massage roller 4 can be ejected from the adjustment chamber 19.

[0036] And please see Figure 5 The limiting component 28 is disposed outside the adjusting chamber 19. The output end of the limiting component 28 passes through the adjusting chamber 19 and is fixedly connected to the limiting plate 29. The adjusting plate 20 has a limiting groove 30, which is adapted to the limiting plate 29. The limiting component 28 is a self-locking electric actuator. After the limiting component 28 is activated, it drives the limiting plate 29 to move into the limiting groove 30, thereby limiting the adjusting plate 20 and preventing it from being driven by the spring 23.

[0037] Furthermore, please refer to Figure 6The rotating massage block 5 has an oil outlet 39, the turntable 32 has an oil storage tank 40, the overall rotating component 31 is disposed on the other side of the flipping block 18, the turntable 32 is disposed at the output end of the overall rotating component 31, a plurality of pump bodies 33 are sequentially disposed inside the oil storage tank 40, a plurality of rotating massage blocks 5 are sequentially rotatably connected to the turntable 32, the output ends of the plurality of pump bodies 33 are respectively connected to the corresponding rotating massage block 5, the oil inlet 34 is connected to the oil storage tank 40, the internal rotating component 35 is disposed inside the turntable 32, the inside of the turntable 32 has an annular groove 41, one end of the rotating auxiliary rod 36 is slidably connected to the annular groove 41, the output end of the internal rotating component 35 and the other end of the rotating auxiliary rod 36 are both fixedly connected to the rotating telescopic component 37, and the output end of the rotating telescopic component 37 is fixedly connected to the kneading block 38.

[0038] Both the overall rotating component 31 and the internal rotating component 35 are self-locking motors, and the rotating telescopic component 37 is a self-locking electric push rod. When a localized facial muscle massage is needed, the turntable 32 is first adjusted to the side of the muscle. At this time, the overall rotating component 31 is activated, driving the turntable 32 and multiple rotating massage blocks 5 to rotate. At this time, the pump body 33 is activated, slowly discharging the massage oil from the oil reservoir 40 from the oil outlet 39, thereby providing lubrication and preventing friction damage to the patient's face during rotation. After the rotational massage is completed, the rotating telescopic component 37 is activated, bringing the kneading block 38 into contact with the patient's muscle sore points. At this time, the internal rotating component 35 is activated, driving the kneading block 38 to knead and massage the muscle sore points, simulating the thumb massage of a medical professional. At the same time, the rotating auxiliary rod 36 improves the stability of the rotating telescopic component 37, ultimately allowing for further massage targeting the patient's specific pain points, significantly improving the massage quality and effectively reducing the patient's soreness.

[0039] Finally, please see Figure 8Two first rotating blocks 42 are sequentially disposed on the lower expansion plate 2, and multiple second rotating blocks 43 are sequentially disposed on the upper expansion plate 1. The multiple second rotating blocks 43 are disposed on both sides of the first rotating blocks 42. Each second rotating block 43 has a torsion spring 45 groove. One end of each of the multiple rotating rods 44 is fixedly connected to one side of the corresponding first rotating block 42, and the other end of each of the multiple rotating rods 44 is rotatably connected to the corresponding torsion spring 45 groove. The multiple torsion springs 45 are respectively sleeved on the outside of the corresponding rotating rods 44. During oral cavity expansion, the torsion springs 45 drive the rotating rods 44 to rotate, causing the first rotating block 42 to rotate between the two second rotating blocks 43, ultimately opening the upper expansion plate 1 and the lower expansion plate 2, thus expanding the oral cavity. Furthermore, the output end of the self-locking electric push rod of this application is equipped with a pressure sensor, which can detect the applied pressure and thus adjust the appropriate massage intensity.

[0040] When using the oral cavity expansion device for oral examination according to this embodiment, during the oral examination, the upper expansion plate 1 and the lower expansion plate 2 are first used to expand the patient's oral cavity. Then, the bidirectional adjustment mechanism can adjust the two massage components in opposite directions, so that the massage roller 4 is close to or away from the patient's face. At this time, it is necessary to adjust the pressure of the massage roller 4: first, the limiting mechanism limits the adjustment plate 20 to keep its position unchanged, and then the spring 23 adjustment mechanism is activated to adjust the contraction position of the spring 23. When the spring 23 is continuously compressed, the limiting mechanism opens. The greater the pressure of the massage rollers 4 on the adjustment plate 20, the less pressure the massage rollers 4 will have when the spring 23 is stretched. This allows for adjustment of the pressure of the massage rollers 4 to suit the massage intensity requirements of different patients. It can also be used for massage requirements of different face shapes. By excessively stretching the spring 23, the pop-out distance of the adjustment plate 20 is limited, so that some of the massage rollers 4 can pop out completely, while the remaining massage rollers 4 pop out with a limited distance. This allows for adaptation to different face shapes and can also achieve targeted massage of the patient's masseter and temporalis muscles.

[0041] When a localized facial muscle massage is needed, the flipping mechanism is first activated, causing the flipping block 18 to flip, thus exchanging the positions of the massage roller 4 and the rotating massage block 5. Then, the turntable 32 is adjusted to the side of the specific sore muscle. At this time, the overall rotating component 31 is activated, causing the turntable 32 and multiple rotating massage blocks 5 to rotate. At this time, the pump body 33 is activated, slowly discharging the massage oil from the oil reservoir 40 from the oil outlet 39, thereby providing lubrication and preventing friction damage to the patient's face during rotation. After the rotational massage is completed, the rotating telescopic component 37 is activated, causing the kneading block 38 to come into contact with the patient's sore muscle points. At this time, the internal rotating component 35 is activated, causing the kneading block 38 to knead and massage the sore muscle points, simulating the thumb massage of a medical professional. At the same time, the rotating auxiliary rod 36 improves the stability of the rotating telescopic component 37. Finally, the massage can be further targeted at the patient's specific pain points, significantly improving the massage quality and effectively reducing the patient's soreness.

[0042] With the above-described structure, multiple massage rollers 4 are adjusted and continuously roll on the patient's face. After being flipped by the flipping mechanism, the rotating massage block 5 performs localized rotational massage. This significantly improves the massage quality and enhances the patient's comfort during prolonged oral examinations compared to traditional single pressure components.

[0043] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
