Description

Technical Field

[0001] This invention belongs to the technical field of strabismus correction devices, specifically relating to a strabismus correction device. Background Technology

[0002] Strabismus, commonly known as "cross-eyed" or "squinting," is a common eye condition characterized by the inability of both eyes to simultaneously focus on the same object. Normally, our eyes move synchronously and focus on the same object, and the brain combines the images seen by both eyes into a clear, three-dimensional image. However, when the muscles or nerves controlling eye movement malfunction, this coordination becomes disordered—one eye may look straight ahead while the other deviates to the side. Strabismus can be corrected through glasses, vision training, prism correction, medication, and surgery. Currently, binocular single vision rehabilitation training is typically performed using strabismus correction devices. However, many existing strabismus correction devices suffer from "functional separation" defects. 1. Some strabismus correction devices are designed with training programs only for a single type of esotropia or exotropia, and cannot meet the training needs of patients with both esotropia and exotropia at the same time. Patients need to change multiple devices to complete full correction. 2. Existing strabismus correction devices generally ignore the correlation between strabismus and habitual head deviation. Strabismus patients often develop a habit of head deviation due to visual compensation, and simple eye training cannot correct this head problem at the same time, resulting in abnormal head posture after correction and affecting the overall correction effect. 3. In traditional strabismus training equipment, the horizontal position and height adjustment of the object (training target carrier) often require multiple sets of motors or complex mechanical structures, which increases the size and cost of the equipment; 4. Existing equipment relies heavily on "manual reminders" or "fixed constraints" to correct head deviation: manual reminders are delayed and cannot intervene in head deviation in real time.

[0003] For example, patent CN112515844B discloses a strabismus correction device, including a base plate, a placement box, a support base, a facial support frame, a support frame, a fixing ring, a lifting base, a telescopic rod, and a correction rod. In use, the height of the lifting base is adjusted using an adjustment knob to suit the patient's training height. Then, the chin is placed inside the facial support frame, and its internal memory metal frame adjusts the arc of the facial support frame to achieve maximum fit between the patient's chin and the frame, providing support for the chin and fixing the face. This allows the patient to avoid head movements during strabismus correction training, relying solely on eye movements to switch perspectives, thus effectively enhancing the training effect.

[0004] However, the above-mentioned technical solution uses a face support frame made of shape memory alloy to fix the patient's face, so as to avoid the change of perspective caused by head movement during strabismus correction training. However, since the face support frame is made of shape memory alloy, when the patient's head turns, it will squeeze the face support frame, causing it to deform. This reduces the fixation effect on the patient's face and greatly reduces the strabismus cycle effect. In addition, the support frame is set on the face support frame. If the face support frame deforms, it will inevitably affect the balance of the support frame, thus affecting the strabismus training effect. Furthermore, the height of the support frame is fixed, which cannot be adapted to patients with different eye heights. Moreover, the above-mentioned technical solution can only use the correction rod to drive the patient's eyeball to rotate, resulting in a single eye training mode and poor strabismus training effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of existing strabismus correction devices having poor strabismus training effects and being unsuitable for patients with different eye heights.

[0006] To achieve the above objectives, the technical approach adopted by this invention is as follows: A strabismus correction device is provided, comprising a training platform, a strabismus correction mechanism, a position adjustment mechanism, and a head correction mechanism; wherein the position adjustment mechanism is connected to the strabismus correction mechanism, and both the position adjustment mechanism and the head correction mechanism are mounted on the training platform. This invention allows for adjustment of the height and horizontal position of the strabismus correction mechanism via the position adjustment mechanism, thus matching it to patients with different eye heights and enabling tracking training. Furthermore, the head correction mechanism automatically corrects the patient's head during strabismus training, preventing head displacement and ensuring the effectiveness of the strabismus correction training.

[0007] Based on the above technical concept, the technical solution adopted by this invention is as follows: A strabismus correction device includes: The training platform is equipped with two primary adjustment screws; The strabismus correction mechanism is located at the top of the position adjustment mechanism and is used to assist the patient's eye movements in circles or figure-eight motions to correct strabismus. The position adjustment mechanism is connected to two first adjustment screws at the lower end and to the strabismus correction mechanism at the upper end. It is used to adjust the height of the strabismus correction mechanism to match the eye height of different patients, and to move the horizontal strabismus correction mechanism so that the patient's eyeballs follow the moving strabismus correction mechanism to move left and right, thereby correcting the strabismus of the patient's eyes. The head correction mechanism is set on the training table and located to the side of the strabismus correction mechanism to prevent the patient's head from shifting during the strabismus correction process.

[0008] To facilitate adjustment of the height and horizontal position of the strabismus correction mechanism, in the above technical solution, preferably, the position adjustment mechanism includes: The C-shaped movable column is connected to the corresponding first adjusting screw, and the side of the C-shaped movable column is provided with a mounting groove, and the inner wall of the mounting groove is provided with a height adjusting rack. Two adjustment components are symmetrically arranged at both ends of the C-shaped movable column; A horizontal adjustment screw is positioned between two adjustment components. Both ends of the horizontal adjustment screw are connected to the adjustment components on the same side, and the horizontal adjustment screw is sleeved with the strabismus correction mechanism.

[0009] To achieve rapid switching of adjustment direction, the above technical solution is further defined as follows: Each adjustment component includes: The second driver is slidably mounted in the mounting slot; Adjust the direction switch, one end of which is connected to the output of the second driver, and the other end is connected to the end of the horizontal adjustment screw; The first gear has a through hole in the center, which is used to connect with the direction adjustment switch, and the first gear is engaged with the height adjustment rack.

[0010] To quickly adjust the height of the strabismus correction mechanism or move it horizontally, the above technical solution is further specified, and the adjustment direction switch includes: A sleeve is provided on the output end of the second driver, and the side of the sleeve away from the second driver has an opening; The push plate is located inside the opening of the sleeve and is connected to the bottom surface of the opening of the sleeve through the first elastic element. The I-beam column is slidably installed inside the end of the horizontal adjusting screw, and one end of the I-beam column is slidably provided with an L-shaped adjusting rod, and the other end is provided with a retaining ring, which is in contact with the side of the push plate. Multiple pin blocks, each pin block having one end engaged with the sleeve and the other end engaged with the first gear or retaining ring.

[0011] To further enhance the strabismus training effect of the overall device, the above technical solution is further specified, and the strabismus correction mechanism includes: The movable block is connected to the horizontal adjusting screw, and the side of the movable block is provided with an 8-shaped groove; The figure-eight training component is set in the figure-eight groove on the side of the moving block; The rotating training component is located on the other side of the moving block.

[0012] To further specify the above technical solution, the figure-eight training component includes: The third driver is embedded inside the moving block, and the output end of the third driver is equipped with a second gear; Two driven gear rings, each driven gear ring having a semi-circular groove at its tooth groove, and the two driven gear rings being meshed together, with one driven gear ring meshing with a second gear; The first training ball is located in the semi-circular groove of one of the driven toothed rings and is in contact with the inner wall of the figure-eight groove.

[0013] To further specify the above technical solution, the first training ball includes: The first training ball itself; Two pointer rods are symmetrically arranged on both sides of the first training ball body, and one of the pointer rods is in contact with the inner wall of the figure-eight groove; The guide post is located at the bottom of the first training ball body and is situated within a semi-circular groove.

[0014] To achieve timely head correction and prevent head displacement, the aforementioned technical solutions are further specified, and the head correction mechanism includes: A fixed frame is installed on the training platform, and a telescopic rod is provided on the bottom surface of the fixed frame; A helmet limiting box is connected to the movable end of a telescopic rod, and a helmet is slidably mounted on the side of the helmet limiting box; The auxiliary correction component is located inside the helmet's limiting box and is connected to the helmet.

[0015] To further specify the above technical solution, the auxiliary correction components include: Turn the lever to connect it to the outer side of the helmet; Two gravity blocks are symmetrically placed on both sides of the helmet, and each gravity block is connected to the helmet by a pull rope; The lever plate is located below the two gravity blocks and is rotatably connected to the inner side of the helmet limit box.

[0016] To further limit the above technical solution, the position adjustment mechanism also includes a baffle to prevent the strabismus correction mechanism from rotating synchronously with the horizontal adjustment screw. The baffle is detachably connected to the two adjustment components.

[0017] To facilitate medical staff in switching the adjustment direction, the above technical solution is further refined by providing an L-shaped through hole on the horizontal adjustment screw to facilitate the passage of the L-shaped adjustment rod.

[0018] Beneficial effects: I. This invention, through the combined design of a position adjustment mechanism and a strabismus correction mechanism, allows the height of the strabismus correction mechanism to be adjusted according to the patient's eye height, thus matching the use of patients with different eye heights. Furthermore, the position adjustment mechanism and the strabismus correction mechanism are matched to conduct tracking training for patients with esotropia or exotropia, that is, to drive the patient's eyes to move back and forth in the horizontal direction, so as to exercise the patient's eye muscles and improve the strabismus correction effect. Second, the strabismus correction mechanism provided by the inventor can not only assist the patient's eyeballs in circling training, but also assist the patient's eyeballs in rotating along a figure-eight trajectory. At the "intersection" and "arc segment" of the figure-eight trajectory, key extraocular muscles such as the medial rectus muscle, lateral rectus muscle, and superior oblique muscle of the patient's eye can be exercised to improve the patient's eye movement flexibility and enhance the patient's binocular coordination ability. The various types of strabismus training improve the strabismus correction training effect of the overall device. Third, the combined design of the helmet, lever plate and rotating lever provided by the present invention allows the patient's head to rotate synchronously during strabismus correction training. The lever plate pushes the rotating lever under the action of the gravity block, making the rotating lever perpendicular to the strabismus correction mechanism. This straightens the helmet connected to the rotating lever, realizing the actual intervention of head deviation, reducing the patient's habit of compensating by tilting their head, and further improving the strabismus correction effect of the overall device. IV. This invention utilizes a combined design of a pin block, a sleeve, a push plate, and a first gear. When one end of the pin block is engaged with the first gear and the other end is engaged with the sleeve, the first gear rotates. When adjusting the height of the horizontal adjustment screw, the horizontal adjustment screw does not rotate synchronously with the first gear. When one end of the pin block is engaged with the push plate and the other end is engaged with the sleeve, the first gear rotates, causing the horizontal adjustment screw to rotate synchronously. This allows the strabismus correction mechanism mounted on the horizontal adjustment screw to move linearly, enabling tracking training for strabismus patients. The structure is simple and easy to use. Fifth, through the combined design of the strabismus correction mechanism and the baffle, this invention can prevent the strabismus correction mechanism from rotating synchronously with the horizontal adjustment screw during the linear movement of the horizontal adjustment screw, thereby ensuring that strabismus training can proceed normally.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] In the description of this invention, it should be understood that the terms "length direction," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features limited to "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The inventors' research found that current strabismus correction training devices, when used, 1. A face support frame made of shape memory alloy is used to fix the patient's face in order to avoid the change of perspective caused by head movement when receiving strabismus correction training. However, since the face support frame is made of shape memory alloy, when the patient's head turns, it will squeeze the face support frame, causing the face support frame to deform, thereby reducing the fixation effect of the patient's face and greatly reducing the strabismus training effect. 2. The above-mentioned support frame is set on the face support frame. If the face support frame deforms, it will inevitably affect the balance of the support frame, thus affecting the strabismus training effect. In addition, the height of the support frame is fixed, which cannot be applied to patients with different eye heights. Furthermore, it can only use the correction rod to drive the patient's eyeballs to rotate, resulting in a single eye training mode and poor strabismus training effect.

[0026] Based on the above findings, this application proposes a strabismus correction device comprising a training table 1, a position adjustment mechanism 2, a strabismus correction mechanism 3, and a head correction mechanism 4. The device is designed to automatically correct the patient's head position during strabismus training, offers multiple eye training modes to improve training effectiveness, and allows adjustment of the height of the strabismus correction mechanism 3 according to the patient's eye position, making it suitable for patients with different eye positions. Specifically: 1. The position adjustment mechanism 2 can not only adjust the height of the strabismus correction mechanism 3 to suit patients with different eye positions, but also work in conjunction with the strabismus correction mechanism 3 to conduct strabismus training for patients with esotropia or exotropia, thereby improving the overall strabismus training effect of the device. 2. The strabismus correction mechanism 3 can not only perform figure-eight eye movement training on the patient's eyes, with both eyes following the movement of the ball to ensure that the line of sight always "catches" the training ball and avoid visual lag, but it can also work with the position adjustment mechanism 2 to drive the patient's eyes to move back and forth in the horizontal direction, so as to perform all-round eye movements on the patient's eyes, balance the exercise of the medial oblique muscle, abductor muscle and other extraocular muscles, improve the ability of eye coordination, and reduce the habit of head tilting for compensation. 3. The head correction mechanism 4 can correct the patient's strabismus during training, keeping the head looking forward without manual intervention, thus improving the convenience of strabismus training and patient compliance.

[0027] Example 1 This embodiment provides a strabismus correction device, such as... Figures 1 to 16 As shown, it includes a training platform 1, a position adjustment mechanism 2, a strabismus correction mechanism 3, and a head correction mechanism 4.

[0028] The training platform 1 includes a training board and four support legs fixedly mounted on the bottom surface of the training board. Two first strip-shaped grooves are formed on the upper surface of the training board, and a first driver and a first adjusting screw 11 are respectively fixedly mounted inside the two first strip-shaped grooves. Specifically, one end of the first adjusting screw 11 is fixedly connected to the output end of the first driver, and the other end is rotatably connected to the inside of the first strip-shaped groove. The first adjusting screw 11 is also threadedly connected to the position adjustment mechanism 2. The first driver provided in this embodiment is prior art, and this embodiment does not improve upon it. For example, the first driver is a rotary motor. The position adjustment mechanism 2 includes a C-shaped moving column 21, a horizontal adjusting screw 22, and two adjusting components.

[0029] The C-shaped moving column 21 is a square columnar structure with a threaded hole at the bottom, which is used to connect with the corresponding first adjusting screw 11. In actual use, the first driver drives the first adjusting screw 11 to rotate. The C-shaped moving column 21 always remains vertical under the squeezing force of the inner wall of the first strip groove. Then, under the threaded connection with the first adjusting screw 11, the C-shaped moving column 21 moves horizontally in the first strip groove. The C-shaped movable column 21 has a second groove on its two opposite sides; the second groove is used to connect with the corresponding adjustment component. The horizontal adjusting screw 22 is located between the two adjusting components, and each end of the horizontal adjusting screw 22 is provided with a sliding groove, and the horizontal adjusting screw 22 is provided with an L-shaped through hole, which communicates with the sliding groove; wherein, each sliding groove is used to slide with the corresponding adjusting component; Each adjustment component includes a second driver 23, an adjustment direction switch 24, a first gear 25, a first elastic element 26, and a baffle 27; Specifically, a height adjustment rack 21a is fixedly provided on the inner side of each second strip groove, and the second driver 23 is located inside the second strip groove and is slidably connected to the inner wall of the second strip groove; wherein, in the embodiment of the present invention, the second driver 23 and the sliding connection method between the second driver 23 and the inner wall of the second strip groove are existing technologies, and the embodiment of the present invention does not improve on this; preferably, the second driver 23 is a rotary motor.

[0030] The direction switcher 24 is fixedly connected to the output end of the second driver 23; the direction switcher 24 includes a sleeve 24a, a push plate 24b, an I-beam 24c, multiple pin blocks 24d, an L-shaped adjusting rod 24e, and a retaining ring 24f; The sleeve 24a is a cylindrical structure with an opening. The bottom surface of the sleeve 24a is fixedly connected to the output end of the second driver 23, and the open end of the sleeve 24a is in contact with the end of the horizontal adjusting screw 22. Specifically, multiple through holes are provided on the side wall of the sleeve 24a, and each pin block 24d is slidably disposed inside the corresponding through hole, and each pin block 24d is connected to the through hole. Each pin block 24d is a strip-shaped block structure, and a first magnetic suction piece is fixedly provided at the bottom of each pin block 24d. The first elastic element 26 and the push plate 24b are both located inside the opening of the sleeve 24a; specifically, one end of the first elastic element 26 is fixedly connected to the bottom surface of the opening of the sleeve 24a, and the other end is fixedly connected to the push plate 24b; wherein, the push plate 24b is a circular sheet structure. It should be noted that the first elastic element 26 provided in the embodiments of the present invention is prior art, and the embodiments of the present invention do not improve it. Preferably, the first elastic element 26 is a spring. The I-beam 24c is slidably disposed in the sliding groove at the end of the horizontal adjusting screw 22; specifically, the two opposite sides of the I-beam 24c are provided with grooves, and a second elastic element 28 is fixedly disposed inside each groove, and the two ends of the second elastic element 28 are respectively fixedly connected to the two sides of the groove; wherein, the second elastic element 28 is the prior art, and the present invention does not limit the structure of the second elastic element 28; preferably, the second elastic element 28 is a spring. The L-shaped adjusting rod 24e is located in the sliding groove at the end of the horizontal adjusting screw 22, and one end of the L-shaped adjusting rod 24e is slidably connected to the I-beam 24c, while the other end passes through the L-shaped through hole of the horizontal adjusting screw 22 and is located on the outside of the horizontal adjusting screw 22. The retaining ring 24f is fixedly disposed on the side of the I-beam 24c away from the L-shaped adjusting rod 24e and is in contact with the push plate 24b. Specifically, the retaining ring 24f is a circular plate structure, and multiple circumferentially arranged arc-shaped grooves are provided on the side of the retaining ring 24f. Each arc-shaped groove is used to engage with the corresponding pin block 24d. The bottom surface of each arc-shaped groove is fixedly provided with a second magnetic piece, which is used to magnetically connect with the first magnetic piece at the bottom of the corresponding pin block 24d.

[0031] The first gear 25 has a through hole at its center, which is used to engage with the sleeve 24a, and the first gear 25 is rotatably connected with the sleeve 24a. Specifically, the inner wall of the central through hole of the first gear 25 is provided with a plurality of circumferentially arranged slots, each slot being used to engage with the end of the corresponding pin block 24d away from the retaining ring 24f.

[0032] The baffle 27 has a directional plate-like structure and is detachably connected to the C-shaped movable column 21. In this embodiment of the invention, the detachable connection method between the baffle 27 and the two adjusting components is the prior art, and this embodiment of the invention does not improve upon it. For example, the detachable method is a bolt connection or a snap-fit ​​connection.

[0033] In this way, while the horizontal adjustment screw 22 drives the strabismus correction mechanism 3 to move laterally, the strabismus correction mechanism 3 will not rotate synchronously with the horizontal adjustment screw 22.

[0034] In the initial state, both the first elastic element 26 and the second elastic element 28 are in their natural state. At this time, the push plate 24b is located directly below the through hole of the sleeve 24a, so that one end of each pin block 24d is located in the through hole of the sleeve 24a, and the other end is located in the groove on the inner wall of the central through hole of the first gear 25.

[0035] The working principle of the position adjustment mechanism 2 provided in this embodiment of the invention is as follows: 1. Adjust the height of the strabismus correction mechanism 3 to match and suit patients with different eye heights; The second driver 23 is activated, which drives the sleeve 24a to rotate. The sleeve 24a drives the first gear 25 to rotate synchronously through each pin block 24d. At this time, since the sleeve 24a is in contact with the end of the horizontal adjusting screw 22 and the push plate 24b is in contact with the retaining ring 24f, the sleeve 24a does not rotate synchronously with the horizontal adjusting screw 22 while rotating, thus keeping the position of the strabismus correction mechanism 3 on the horizontal adjusting screw 22 constant in the horizontal direction. Meanwhile, under the meshing connection between the first gear 25 and the height adjustment rack 21a, the first gear 25 drives the second driver 23 to move up and down synchronously, thereby realizing the height adjustment of the strabismus correction mechanism 3 so as to match and be suitable for patients with different eye heights; Second, it drives the strabismus correction mechanism 3 to move back and forth linearly on the horizontal adjustment screw 22 to perform visual tracking training for the patient; First, medical staff hold the L-shaped adjusting rod 24e and push it into the sleeve 24b. The L-shaped adjusting rod 24e drives the retaining ring 24f to move in the same direction through the I-beam 24c until the retaining ring 24f is directly below the through hole of the sleeve 24b. At this time, each pin block 24d enters the corresponding arc-shaped groove on the side of the retaining ring 24f under the magnetic attraction of the first and second magnetic plates, and is magnetically connected to the retaining ring 24f. At this time, one end of each pin block 24d is located in the through hole of the sleeve 24b, and the other end is located in the corresponding arc-shaped groove on the retaining ring 24f, thereby realizing the engagement of the sleeve 24b and the retaining ring 24f, and further realizing the engagement of the sleeve 24b and the horizontal adjusting screw 22. During this process, both the first elastic element 26 and the second elastic element 28 are compressed. Secondly, the medical staff hold the L-shaped adjusting rod 24e and move the L-shaped adjusting rod 24e horizontally. In this way, under the combined action of the second elastic element and the inner wall of the L-shaped through hole of the horizontal adjusting screw 22, the position of the L-shaped adjusting rod 24e is fixed, thereby fixing the position of the I-beam 24c connected to the L-shaped adjusting rod 24e. Then, the second driver 23 is activated, which drives the sleeve 24a to rotate. The sleeve 24a drives the retaining ring 24f to rotate synchronously through each pin block 24d. The retaining ring 24f drives the horizontal adjustment screw 22 to rotate synchronously through the I-beam 24c. The horizontal adjustment screw 22 drives the strabismus correction mechanism 3 to move linearly. Under the action of the baffle 27, the strabismus correction mechanism 3 will not rotate synchronously with the horizontal adjustment screw 22. The strabismus correction mechanism 3 can be moved to the left or right by controlling the horizontal adjustment screw 22 to rotate forward or backward, so as to repeatedly exercise the muscles around the patient's strabismus eye in the opposite direction, thereby achieving tracking training for the patient.

[0036] In practical applications, other existing components can be used to further fix the position of the L-shaped adjusting rod 24e. For example, an L-shaped silicone sealing block can be inserted into the L-shaped through hole of the horizontal adjusting screw 22 to further fix the position of the L-shaped adjusting rod 24e.

[0037] The strabismus correction mechanism 3 includes a moving block 31, a figure-eight training component 32, and a rotating training component 33; wherein the figure-eight training component 32 and the rotating training component 33 are both fixedly mounted on the moving block 31. The movable block 31 is a square block structure with a threaded hole in the center, which is used to connect with the horizontal adjusting screw 22; wherein, an 8-shaped groove is provided on one side of the movable block 31. The figure-eight training component 32 is fixedly disposed inside the figure-eight groove on the movable block 31; the figure-eight training component 32 includes a third driver, a second gear 32a, two driven gear rings 32b and a first training ball 32c; Specifically, the third driver is embedded inside the moving block 31, and the output end of the third driver is fixedly connected to the second gear 32a; Both driven gear rings 32b are rotatably disposed in the figure-eight shaped groove of the movable block 31, and the two driven gear rings 32b are meshed together, with one driven gear ring 32b meshing with the second gear 32a; wherein, the thickness of the driven gear ring 32b is greater than the thickness of the second gear 32a. Specifically, one of the tooth grooves of the two driven gear rings 32b is a semi-circular annular groove 32b-1. The two semi-circular grooves are symmetrically arranged. In this way, when the two driven gears 32b rotate, the two semi-circular annular grooves 32b-1 approach each other until they merge and then move away from each other. The first training ball 32c is limited within one of the semi-circular annular grooves 32b-1. Specifically, the first training ball 32c includes a first training ball body 32c-1, two pointer rods 32c-2, and a guide post 32c-3. Specifically, the color of the first training ball body 32c-1 can be set to red, blue, or green, or other colors that are easy for patients to distinguish; Two pointer rods 32c-2 are fixedly installed at both ends of the first training ball body 32c-1; each pointer rod 32c-2 is a triangular plate structure, and the side of the pointer rod 32c-2 is in contact with the inner wall of the figure-eight groove. The guide post 32c-3 is a circular body and is fixedly installed at the bottom end of the first training ball body 32c-1. The guide post 32c-3 is located in one of the semi-circular annular grooves 32b-1. The bottom area of ​​the semi-circular annular groove 32b-1 is half the bottom area of ​​the guide post 32c-3.

[0038] The working principle of the figure-eight training component 32 provided in this embodiment of the invention is as follows: In the initial state, the guide post 32c-3 is located in one of the semi-circular annular grooves 32b-1; The third drive is activated, which rotates the second gear 32a. The second gear 32a rotates the driven gear ring 32b meshing with it. Simultaneously, the driven gear ring 32b rotates the guide post 32c-3, and also rotates the other driven gear ring 32b. At this point, the two semi-circular grooves 32b-1 approach each other until they overlap. The guide post 32c-3 is located within the circular groove formed by the merging of the two semi-circular grooves 32b-1. The two driven gear rings 32b continue to rotate. Guided by the inner wall at the middle corner of the figure-eight groove, the pointer rod 32 at the clamp end of the first training ball body 32c-1 moves in the direction of motion. The end of c-2 is tangent to the side wall at the middle position of the figure-eight groove, so that the pointer rod 32c-2 is positioned above another driven gear ring 32b, thereby causing the guide post 32c-3 to enter the semi-circular annular groove 32b-1 of another driven gear ring 32b. This cycle repeats, allowing the first training ball 32c to rotate along the figure-eight trajectory. During strabismus training, the first training ball 32c can be used to assist the patient in rotating their eyeballs, so as to exercise the key extraocular muscles such as the medial rectus muscle, lateral rectus muscle, and superior oblique muscle, improve the patient's eye movement flexibility, and enhance the patient's binocular coordination. Multiple types of strabismus training improve the overall strabismus correction training effect of the device.

[0039] The rotating training component 33 includes a fourth actuator, a rotating rod 33a, and a second training ball 33b; Specifically, the fourth driver is embedded in the other side of the moving block 31; the output end of the fourth driver is perpendicular to the rotating rod 33a and is fixedly connected to the rotating rod 33a. The second training ball 33b is fixedly mounted at the end of the rotating rod 33a away from the fourth actuator. Similar to the first training ball body 32c-1, the second training ball 33b can be set to a color such as red, blue, or green, which is easy for the patient to distinguish. In actual use, the fourth actuator can be activated, which drives the second training ball 33b to rotate via the rotating rod 33a, thereby assisting the patient's eyeballs in circular movements.

[0040] It should be noted that the third and fourth drives provided in the embodiments of the present invention are both prior art, and the embodiments of the present invention do not make improvements to them. For example, the third and fourth drives are both rotary motors.

[0041] In practical applications, the switching between the figure-eight training component 32 and the rotating training component 33 includes the following steps: First, remove the baffle 27 from the adjustment assembly. Then, engage one end of the pin block 24d with the sleeve 24a and the other end with the retaining ring 24f. This allows the second driver 23 to rotate the horizontal adjustment screw 22 via the direction switcher 24. At this time, the moving block 31 rotates synchronously with the horizontal adjustment screw 22, so that the side of the moving block 31 with the figure-eight training component 32 faces the helmet 43, or the side of the moving block 31 with the rotating training component 33 faces the helmet 43, thus switching the training mode. Finally, install the baffle 27 on the adjustment assembly for subsequent strabismus correction training.

[0042] The head correction mechanism 4 includes a fixing frame 41, a helmet limiting box 42, a helmet 43, and auxiliary correction components; Specifically, the fixing frame 41 has a C-shaped structure and is fixedly installed on the training platform 1; wherein, a telescopic rod 41a is fixedly provided on the bottom surface of the fixing frame 41, and the movable end of the telescopic rod 41a is fixedly connected to the helmet limiting box 42. The helmet limiting box 42 is a square structure with an opening, and the helmet 43 and the auxiliary correction component are both disposed in the opening of the helmet limiting box 42; wherein, the helmet 43 is rotatably connected to the helmet limiting box 42, and the rotatable connection method between the helmet limiting box 42 and the helmet 43 in this embodiment of the invention is the prior art, and this embodiment of the invention does not improve it. For example, the helmet limiting box 42 is rotatably connected to the helmet limiting box 42 via a rotating shaft; The auxiliary correction component includes a rotating lever 44, two gravity blocks 45, a lever plate 46, and two pull ropes 47; correspondingly, two limiting rings 42a are also fixed inside the opening of the helmet limiting box 42, and each limiting ring 42a is used to engage with the corresponding pull rope 47. Specifically, the rotating lever 44 is a long strip-shaped plate structure, and the rotating lever 44 is fixedly installed at the rear end of the helmet 43; The lever plate 46 is a square plate structure, and the center of the lever plate 46 is rotatably connected to the inner wall of the opening of the helmet limiting box 42; wherein, the lever plate 46 and the rotating lever 44 are set perpendicular to each other, and the rotating lever 44 is located directly in front of the lever plate 46; the lever plate 46 always maintains a balanced state when the patient's head does not shift. Two pull ropes 47 are symmetrically arranged between the lever plate 46 and the rotating lever 44. One end of each pull rope 47 passes through the limiting ring 42a on the same side and is fixedly connected to the outermost end of the helmet 43, and the other end is fixedly connected to the corresponding gravity block 45. The two gravity blocks 45 are symmetrically arranged at both ends of the lever plate 46 and are located above the end of the lever plate 46.

[0043] In actual use, an eye shield 5 is rotatably connected to each end of the helmet limiting box 42; specifically, the eye shield 5 is made of elastic material so that the patient can bend the eye shield 5 to cover the eye on the same side.

[0044] It should be noted that the telescopic rod 41a provided in the embodiments of the present invention is prior art, and the embodiments of the present invention do not improve upon it. For example, the telescopic rod 41a is an electric telescopic rod.

[0045] Taking the correction of strabismus in the right eye of a patient with esotropia as an example, the working principle of the head correction mechanism 4 provided in this embodiment of the invention is as follows: Insert the patient’s head into the helmet 43, then have the patient hold the eye shield 5 on the left side of the helmet limit box 42 and bend the eye shield 5 to cover the patient’s left eye so that strabismus correction training can be performed on the patient’s right eye. During training, if the patient’s head shifts to the right, the helmet 43 rotates to the left along with the movable end of the rotating lever 44. At the same time, the end of the pull rope 47 that is fixedly connected to the right side of the helmet 43 gradually approaches the limiting ring 42a on the same side. At this time, the gravity block 45 connected to the right pull rope 47 moves downward and presses the right end of the lever plate 46 downward, thereby causing the left end of the lever plate 46 to tilt upward. As the left end of the lever plate 46 tilts upward, it contacts the side of the rotating lever 44, thereby pushing the movable end of the rotating lever 44 to rotate to the right, so that the rotating lever 44 is once again perpendicular to the lever plate 46. At this time, the helmet 43, which is fixedly connected to the rotating lever 44, no longer shifts, thus achieving timely correction of the patient's head.

[0046] If the patient's head tilts to the left, the opposite occurs when the patient's head tilts to the right. Under the action of the left-side gravity block 45, the right end of the lever plate 46 tilts upward so as to push the rotating lever 44 to the left, thereby straightening the helmet 43 and achieving timely correction of the patient's head. This will not be elaborated further here.

[0047] Application Cases Taking the correction of strabismus in the right eye of a patient with esotropia as an example, the working method of the strabismus correction device provided in this embodiment of the invention includes the following steps: S1: The patient's head is inside the helmet 43, and the patient holds the eye shield 5 on the left side of the helmet limit box 42 and bends the eye shield 5 to cover the patient's left eye. S2: Adjust the height of the strabismus correction mechanism 3 according to the patient's eye height; Specifically, the second driver 23 is activated, which drives the sleeve 24a to rotate. The sleeve 24a drives the first gear 25 to rotate synchronously through each pin block 24d. At the same time, under the meshing connection between the first gear 25 and the height adjustment rack 21a, the first gear 25 drives the second driver 23 to move up and down synchronously, so that the height of the strabismus correction mechanism 3 is at the same level as the patient's eyeball. S3: Use strabismus correction device 3 to perform strabismus correction training on the patient; this step includes the following three training modes; Mode 1 involves guiding the patient's eyeballs to rotate along a figure-eight pattern; specifically, this includes the following steps: S301: Start the second drive 23. The second drive 23 drives the moving block 31 to move to the front of the helmet 43 through the horizontal adjustment screw 22. S302: The third drive is activated, which drives the second gear 32a to rotate. The second gear 32a drives the driven gear ring 32b meshing with it to rotate. Simultaneously, the driven gear ring 32b drives the guide post 32c-3 to rotate synchronously, and also drives another driven gear ring 32b to rotate synchronously. At this time, when the two semi-circular annular grooves 32b-1 approach each other until they overlap, the guide post 32c-3 is located within the circular groove formed by the merging of the two semi-circular annular grooves 32b-1, thus... As the driven gear ring 32b continues to rotate, guided by the inner wall at the middle corner of the figure-eight groove, the end of the pointer rod 32c-2 located at the clamp end of the first training ball body 32c-1 in the direction of movement is tangent to the middle corner of the figure-eight groove, so that the pointer rod 32c-2 is located above the other driven gear ring 32b, so that the guide post 32c-3 enters the semi-circular annular groove 32b-1 of the other driven gear ring 32b, and so on, repeating in this way, so that the first training ball 32c rotates along the figure-eight trajectory; Mode 2 involves guiding the patient's eyeballs to rotate in circles; specifically, it includes the following steps: S303: Activate the second drive 23. The second drive 23 drives the moving block 31 to move to the front of the helmet 43 through the horizontal adjustment screw 22. S304: Activate the fourth actuator, which drives the second training ball 33b to rotate via the rotating rod 33a, thereby assisting the patient's eyeballs in circumduction. Mode 3 involves guiding the patient's eyes through visual tracking training; specifically, it includes the following steps: S305: Medical staff hold the L-shaped adjusting rod 24e and push it to move into the sleeve 24b. The L-shaped adjusting rod 24e drives the retaining ring 24f to move in the same direction through the I-beam 24c until the retaining ring 24f is directly below the through hole of the sleeve 24b. At this time, each pin block 24d enters the corresponding arc-shaped groove on the side of the retaining ring 24f under the magnetic attraction of the first magnetic plate and the second magnetic plate, and is magnetically connected with the retaining ring 24f. At this time, one end of each pin block 24d is located in the through hole of the sleeve 24b, and the other end is located in the corresponding arc-shaped groove on the retaining ring 24f, thereby realizing the engagement of the sleeve 24b and the retaining ring 24f, and thus realizing the engagement of the sleeve 24b and the horizontal adjusting screw 22. S306: Activate the second actuator 23. The second actuator 23 drives the sleeve 24a to rotate. The sleeve 24a drives the retaining ring 24f to rotate synchronously through each pin block 24d. The retaining ring 24f drives the horizontal adjustment screw 22 to rotate synchronously through the I-beam 24c. The horizontal adjustment screw 22 drives the strabismus correction mechanism 3 to move to the right until the patient feels a slight traction on the outer side of the right eye. Maintain this gaze for about five seconds. S307: The second driver 23 drives the horizontal adjusting screw 22 to rotate in the opposite direction, causing the moving block 31 to move to the left; S308: Repeat steps S301 and S302 in this cycle. Through all-round eye movements, actively stretch the medial oblique and abductor muscles of the patient's right eye, improve the excessive convergence of the eyes, expand the lateral visual field, enhance the ability of eye coordination, and reduce the habit of head tilting as a compensatory mechanism.

[0048] In step S3 above, if the patient's head deviates, the same end of the lever plate 46 on the same side will tilt upward under the action of the gravity block 45 on the side of the helmet 43 in the direction of deviation, so as to correct the rotation lever 44 and thus achieve timely correction of the patient's head.
