[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] See also Figures 1-4 As shown, the present invention provides a technical solution: an adjustable nasopharyngeal carcinoma mouth opening training device, comprising a side panel 1 for supporting a side component, one end of the side panel 1 is provided with a mouth expansion mechanism 2 for adjusting the mouth opening range, and the end of the mouth expansion mechanism 2 away from the side panel 1 is provided with an adjustment mechanism 3 for adjusting the mouth opening angle.

[0018] The side panel 1 is a stable support base, which connects the expansion mechanism 2 for adjusting the mouth opening range and the adjustment mechanism 3 for adjusting the mouth opening angle in sequence. The modular structural layout not only ensures the stability of the connection between each component, but also realizes functional integration. The expansion mechanism 2 is used to control the mouth opening amplitude to adapt to the range requirements of different rehabilitation stages, and the adjustment mechanism 3 is responsible for flexibly adjusting the angle to adapt to the patient's oral physiological structure. The synergistic effect of the two allows the device to meet personalized training parameter adjustments and ensure the stability and safety of the training process through orderly structural connection.

[0019] As an implementation method in this embodiment, please refer to Figure 1-Figure 2 As shown, the expansion mechanism 2 includes a first fixed column 21, which is fixedly connected to one side of one end of the side plate 1. The inner cavity of the side plate 1 is rotatably connected to a screw 22. The end of the screw 22 close to the side plate 1 is fixedly connected to an adjusting disc 23, and the end of the screw 22 away from the adjusting disc 23 is fixedly connected to a limiting column 24.

[0020] When the opening range needs to be adjusted, the adjusting disc 23 is rotated. Since the screw 22 is rotatably connected to the side plate 1, the adjusting disc 23 will drive the screw 22 to rotate together. During this process, the limit column 24 can prevent the movable column 26 from falling off from the screw 22 during movement, thereby ensuring the safety of the mechanism operation.

[0021] As an implementation method in this embodiment, please refer to Figure 1-Figure 2 As shown, there are two groups of first fixed columns 21 symmetrically arranged, and the upper ends of the two groups of symmetrically arranged first fixed columns 21 are fixedly connected to the directional shaft 25 on one side, and the outer side of the screw rod 22 is threadedly connected to the movable column 26, and the two sides of the movable column 26 are closely connected to the side ends of the two groups of symmetrically arranged first fixed columns 21.

[0022] The outer side of the screw rod 22 is threadedly connected to a movable column 26, and both sides of the movable column 26 are in close contact with the side ends of two groups of symmetrically arranged first fixed columns 21, which makes the movable column 26 unable to rotate with the screw rod 22 and can only move along the axial direction of the screw rod 22 under the action of the thread of the screw rod 22.

[0023] As an implementation method in this embodiment, please refer to Figure 1-Figure 3As shown, the upper end of the movable column 26 is rotatably connected to the first connecting rod 27 at one side, and the upper end of the movable column 26 is rotatably connected to the second connecting rod 28 at one side. The end of the first connecting rod 27 away from the movable column 26 is rotatably connected to the expansion plate 29, and the expansion plate 29 is rotatably connected to the movable column 26 through the second connecting rod 28. A slot is provided in the inner cavity of the upper end of the expansion plate 29, and the expansion plate 29 is slidably connected to the outer surface of the directional shaft 25 through the slot.

[0024] When the movable column 26 moves, the first and second connecting rods 27 and 28 pivotally connected at its upper ends also move, thereby driving the expansion plate 29, which is pivotally connected to the ends of the first and second connecting rods 27 and 28 away from the movable column 26, to move. The expansion plate 29 has a notch in its upper end and is slidably connected to the outer surface of the orientation shaft 25 through the notch. The orientation shaft 25 guides and limits the movement of the expansion plate 29, ensuring that the expansion plate 29 can move stably along the direction of the orientation shaft 25, thereby adjusting the opening range.

[0025] As an implementation method in this embodiment, please refer to Figures 1-4 As shown, the adjustment mechanism 3 includes a second fixed column 31, the second fixed column 31 is fixedly connected to one end of the flaring plate 29, the end of the second fixed column 31 away from the flaring plate 29 is fixedly connected to the first connecting plate 32, one end of the first connecting plate 32 is fixedly connected to the connecting column 33, the end of the connecting column 33 close to the first connecting plate 32 is fixedly connected to the guide shaft 34, and the guide shaft 34 passes through the inner cavity of the first connecting plate 32.

[0026] The fixed connection between the second fixed column 31 and the flaring plate 29 ensures the stable connection between the adjustment mechanism 3 and the flaring mechanism 2, providing a solid support foundation for angle adjustment; the sequential connection of the first connecting plate 32 and the connecting column 33 forms a reasonable force conduction path, enhancing the stability of the overall structure; the guide shaft 34 passes through the inner cavity of the first connecting plate 32 and cooperates with the movable plate 35, which not only provides a guide limit for the sliding of the movable plate 35 to avoid offset or shaking during movement, but also ensures the stability and accuracy of the angle adjustment through the rigid connection of the structure, so that the entire adjustment mechanism 3 can always maintain a stable and reliable operating state while realizing flexible angle adjustment, and better adapt to the patient's requirements for angle accuracy and structural safety during oral training.

[0027] As an implementation method in this embodiment, please refer to Figure 4 As shown, a movable plate 35 is slidably connected to the outer side of the guide shaft 34, and an arc-shaped groove 36 is provided in the inner cavity of the movable plate 35. The movable plate 35 is slidably connected to the outer surface of the guide shaft 34 through the arc-shaped groove 36. The end of the movable plate 35 away from the second fixed column 31 is fixedly connected to a soft pad 37 that contacts the patient's mouth.

[0028] The sliding connection formed by the guide shaft 34 and the movable plate 35 through the arc groove 36 provides a trajectory guide for the angle adjustment of the movable plate 35, ensuring that the movable plate 35 moves stably along the preset arc path during rotation, avoiding offset or jamming, and ensuring the accuracy and smoothness of the mouth opening angle adjustment; at the same time, the soft pad 37 at the end of the movable plate 35 away from the second fixed column 31 directly contacts the patient's mouth, which can effectively buffer the contact pressure, reduce the hard friction between the device and the oral tissue, reduce the risk of oral mucosal damage, improve the patient's comfort during training, and allow the patient to complete the training adjustment of the mouth opening angle in a safe and stable state.

[0029] As an implementation method in this embodiment, please refer to Figure 4 As shown, the second fixed column 31 is fixedly connected to the center of one end close to the movable plate 35 with a cylinder 38, and the inner cavity of the cylinder 38 away from the end of the second fixed column 31 is slidably connected to the third connecting rod 39, and the end of the third connecting rod 39 away from the cylinder 38 is fixedly connected to the hinge 310, and the third connecting rod 39 is hinged to the movable plate 35 through the hinge 310.

[0030] The cylinder 38 fixed at the center of the second fixed column 31 provides a stable power source for the angle adjustment of the movable plate 35, ensuring that the adjustment process is labor-saving and controllable; the sliding connection between the cylinder 38 and the third connecting rod 39 realizes the linear transmission of power, and the movable plate 35 is driven by the telescopic movement of the third connecting rod 39; and the hinge 310 connection between the third connecting rod 39 and the movable plate 35 gives the two the flexibility of relative rotation, which not only ensures that the power can be efficiently transmitted to the movable plate 35, but also reserves sufficient freedom for the rotation of the movable plate 35 along the arc groove 36 to avoid structural jamming; the overall structure is driven by the cylinder 38, the connecting rod transmission and the hinge 310 adaptation, so that the angle adjustment of the movable plate 35 is smoother, and can flexibly adapt to the oral training needs of different patients, while ensuring the safety and reliability of the adjustment process.

[0031] Working Principle: The side panel 1 serves as the support base, and the training function is achieved through the coordinated action of the mouth-expanding mechanism 2 and the adjustment mechanism 3. In the mouth-expanding mechanism 2, rotating the adjustment disc 23 drives the screw 22, causing the movable column 26, which is restrained by the first fixed column 21, to move axially along the screw 22. This is then driven by the first and second connecting rods 27 and 28 to push the mouth-expanding plate 29 along the directional axis 25. The directional axis 25 guides and stabilizes the mouth-opening range, while the limiting column 24 prevents the movable column 26 from falling off. In the adjustment mechanism 3, the cylinder 38 on the second fixed column 31 drives the third connecting rod 39 to extend and retract, which, through the hinge 310, drives the movable plate 35 to rotate about the guide axis 34. The movable plate 35 slides along the guide axis 34, relying on the arcuate groove 36 to adjust the mouth-opening angle. The soft pad 37 at the end of the movable plate 35 contacts the patient's mouth to ensure training comfort. The overall mechanism achieves personalized adjustment of the mouth-opening range and angle through the coordination of mechanical transmission and guide limit.
