Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an ophthalmic strabismus correction training device. Background Art

[0002] Strabismus refers to the inability of both eyes to look at the target at the same time. It is an extraocular muscle disease and can be divided into two categories: concomitant strabismus and paralytic strabismus. The main clinical features of concomitant strabismus are no eye movement disorders and equal strabismus in the first and second eye positions; paralytic strabismus has restricted eye movement and diplopia. It can be congenital or caused by trauma or systemic diseases. It needs to be corrected, which requires strabismus correction training to exercise the flexibility of the eye.

[0003] During the process of strabismus correction, factors that affect visual fatigue include light. Poor lighting environment, such as excessive light, can irritate the eyes and increase the burden of eye adjustment, leading to visual fatigue, which can affect strabismus correction. Visual fatigue caused by light can easily make the eyes feel sore, dry, and even have symptoms of double vision such as double vision. These symptoms not only affect the patient's visual quality, but may also aggravate the degree of strabismus. However, existing strabismus correction training devices need to adjust the brightness of indoor light or relocate the position to adjust the visual fatigue caused by too bright light. Each time the indoor light or the position of the device is adjusted according to the light conditions, additional operations are required, which not only increases the complexity of use, but may also affect the continuity and efficiency of correction training.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 , the present invention provides a technical solution:

[0023] See also Figure 1-Figure 4 As shown, an ophthalmic strabismus correction training device includes a frame 1, a U-shaped groove 7 which is wider at the bottom and narrower at the top is opened on the frame 1, a mounting block 2 is arranged on the U-shaped groove 7, the mounting block 2 is slidably connected to the frame 1 through the U-shaped groove 7, the mounting block 2 is connected to a shading plate 4, and the shading plate 4 is arranged on the U-shaped groove 7.

[0024] If the patient feels that the light is glaring, the eyeballs are uncomfortable and feel tired during the process of strabismus, the two mounting blocks 2 on the frame 1 can be slid to the top of the eyes. The sunshade 4 is composed of a plurality of superimposed arc plates, which can be unfolded but restrained from each other. The patient presses one of the mounting blocks 2 to keep it still, and then pulls the other mounting block 2 to expand the extension plate 5. The extension plate 5 forms a baffle above the eyes to block the glaring light. There is no need to perform additional operations to adjust the indoor light or geographical location according to the light conditions each time. This not only reduces the complexity of use, but also does not affect the continuity and efficiency of the correction training.

[0025] There is a certain friction between the mounting block 2 and the mirror frame 1, and this friction requires a certain pulling force to overcome, so the mounting block 2 will not be easily displaced.

[0026] See also Figure 3 The outer wall of the frame 1 is provided with a plurality of teeth, and the mounting block 2 is rotatably connected with a gear 3, which is meshed with the teeth on the outer wall of the frame 1. The meshing connection between the gear 3 and the teeth is usually highly stable, which can prevent accidental sliding or displacement during use, and can make the mounting block 2 more stable when moving.

[0027] See also Figure 1-2A mounting frame 9 is provided on one side of the frame 1, a servo motor 11 is provided on one side of the mounting frame 9, a screw rod 10 is connected to the driving end of the servo motor 11, and a correction plate 12 is threadedly connected to the outer wall of the screw rod 10. The servo motor 11 has high-precision control capability, and can achieve precise driving of the screw rod 10, thereby driving the correction plate 12 to make fine position adjustments, which is very important for strabismus correction training, because precise adjustment can ensure that the training effect reaches the best state.

[0028] See also Figure 1-2 The other end of the screw rod 10 away from the servo motor 11 is rotatably connected to the inner wall of the installation frame 9, and a motor protection frame is provided on the outer wall of the installation frame 9. The servo motor 11 is arranged inside the motor protection frame.

[0029] The main function of the motor protection frame is to protect the servo motor 11 from the influence of the external environment, such as dust, moisture, impact, etc., which helps to extend the service life of the servo motor 11 and reduce failures and damages caused by environmental factors. A battery is installed inside the mounting rod 8 to power the servo motor 11. A single-chip microcomputer is set on the outer wall of the mounting rod 8 to control the operation of the servo motor 11.

[0030] See also Figure 2 A guide rod 13 is fixedly mounted on the inner wall of the mounting frame 9, and the correction plate 12 is slidably connected to the outer wall of the guide rod 13. The guide rod 13 provides a stable sliding track for the correction plate 12, ensuring the stability and accuracy of the correction plate 12 during movement, which helps to reduce the decline in training effect caused by shaking or deviation of the correction plate 12.

[0031] See also Figure 1 A connecting rope is fixedly installed between the mounting frame 9 and the mirror frame 1 , and a mounting rod 8 is fixedly installed at the bottom of the mounting frame 9 .

[0032] The connecting rope can be set to a suitable length between the eyes and the correction plate 12 according to the patient's own situation. The appropriate distance between the correction plate 12 and the eyes is crucial for strabismus correction training. Too close a distance may lead to overcorrection or discomfort, while too far a distance may not achieve the expected correction effect. By adjusting the connecting rope to ensure the appropriate distance, the correction plate 12 can act more accurately on the patient's strabismus problem, thereby enhancing the training effect.

[0033] See also Figure 1 A fixing sleeve 14 is fixedly mounted on the mirror frame 1 , and the other end of the fixing sleeve 14 is fixedly mounted on another mirror frame 1 , and a sliding groove 15 is provided at the bottom of the sunshade 4 .

[0034] The fixing sleeve 14 has a certain elasticity and is convenient to wear. As a key component connecting the two frames 1, the fixing sleeve 14 can ensure a stable connection between the two frames 1. This stability is particularly important when wearing, because it can prevent the device from loosening or falling off when the patient's head shakes or performs training movements, thereby improving the wearing stability.

[0035] See also Figure 1 An extension plate 5 is inserted into the interior of the shading plate 4, and a pull block 6 is fixedly installed on the extension plate 5.

[0036] If the patient wants to further adjust the light, he can hold the pull block 6 to pull out the extension plate 5 to expand the shielding area and better block the light. The extension plate 5 can extend outward, but there will be no situation where the extension plate 5 is separated from the shading plate 4.

[0037] The shading plate 4 is formed by stacking a plurality of arc-shaped plates, and each arc-shaped plate is provided with an extension plate 5 .

[0038] Working principle: If the patient feels that the light is glaring, the eyeballs are uncomfortable and feel tired during the process of strabismus, the two mounting blocks 2 on the frame 1 can be slid to the top of the eyes. The sunshade 4 is composed of a plurality of superimposed arc plates, which can be unfolded but restrained from each other. The patient presses one of the mounting blocks 2 to keep it still, and then pulls the other mounting block 2 to expand the extension plate 5. The extension plate 5 forms a baffle above the eyes to block the glaring light. There is no need to perform additional operations to adjust the indoor light or geographical location according to the light conditions each time. This not only reduces the complexity of use, but also does not affect the continuity and efficiency of the correction training.

[0039] There is a certain friction between the mounting block 2 and the mirror frame 1, and this friction requires a certain pulling force to overcome, so the mounting block 2 will not be easily displaced.

[0040] If the patient wants to further adjust the light, he can hold the pull block 6 to pull out the extension plate 5 to expand the shielding area and better block the light. The extension plate 5 can extend outward, but there will be no situation where the extension plate 5 is separated from the shading plate 4.

[0041] The shading plate 4 is formed by stacking a plurality of arc-shaped plates, and each arc-shaped plate is provided with an extension plate 5 .
