Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an analytical device for evaluating the visual effects of YAG treatment on posterior MIOL visual impairment. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related articles that are used directly or indirectly on the human body, including the necessary computer software. Their purpose of use includes the diagnosis, prevention, monitoring, treatment, or relief of diseases; the diagnosis, monitoring, treatment, relief, or functional compensation of injuries; the examination, replacement, regulation, or support of physiological structures or processes; life support or maintenance; pregnancy control; and the disinfection and sterilization of medical devices, etc., and their efficacy is mainly obtained through physical means, not through pharmacological, immunological, or metabolic means, or although these means are involved, they only play an auxiliary role.

[0003] After YAG laser treatment for intraocular lens (MIOL) implantation, some patients are prone to posterior capsule opacification. It is necessary to measure, analyze, and evaluate visual effect-related indicators using relevant equipment to provide ophthalmologists with objective and accurate diagnostic evidence to assess treatment effectiveness and the recovery of the patient's eye function. Existing equipment requires illumination to ensure clear observation and imaging of the eye structure, helping doctors accurately assess visual effects. However, the illumination source is often installed on the equipment and requires adjustment by medical staff during use. Measurements often require multiple camera angles to ensure accuracy, making the adjustment of existing illumination sources cumbersome and inconvenient.

[0004] Therefore, we propose an analytical device for evaluating the visual effects of YAG treatment on posterior visual impairment of MIOL to address the aforementioned issues. Utility Model Content

[0024] In this embodiment, a lamp post 4 is fixedly installed on the top of the measuring platform 1, and one end of the lighting source 5 is fixedly connected to the top of the lamp post 4. The lamp post 4 can provide support for the lighting source 5.

[0025] In this embodiment, the universal mechanism includes a rotating base 11, a linkage column 12, an L-shaped base 13, a lighting base 14, a linkage component, and a drive component. The rotating base 11 is rotatably mounted on one end of the moving column 9. A linkage hole is provided on one side of the rotating base 11. The linkage column 12 is rotatably mounted on the inner side of the linkage hole. The L-shaped base 13 is fixedly mounted on one end of the linkage column 12. The lighting base 14 is fixedly mounted on one side of the L-shaped base 13. The lighting source 5 is detachably mounted on the lighting base 14. A drive component is provided on the outer side of the moving column 9, and a linkage component is provided on the other end of the linkage column 12.

[0026] In this embodiment, the driving component includes a cylinder 19, a moving ring 18, and an outer grooved ring 17. The outer grooved ring 17 is slidably sleeved on the outer side of the moving column 9, and the moving ring 18 is rotatably sleeved on the outer side of the outer grooved ring 17. A cylinder 19 is fixedly installed on one side of the slider 7. The output end of the cylinder 19 is fixedly connected to one side of the moving ring 18.

[0027] In this embodiment, the linkage component includes an inner groove ring 16 and a ball head rod 15. The ball head rod 15 is fixedly installed at the other end of the linkage column 12. An inner groove ring 16 is fixedly installed on one side of an outer groove ring 17. An inner groove is formed on the inner side of the inner groove ring 16. The ball head end of the ball head rod 15 is slidably installed in the inner groove.

[0028] In this embodiment, a rotating chamber is provided on the inner side of the movable column 9. A rotating servo motor 10 is fixedly installed on one inner wall of the rotating chamber. The output shaft of the rotating servo motor 10 is fixedly connected to the rotating base 11. The rotating servo motor 10 can drive the rotating base 11 to rotate.

[0029] Working Principle: When measuring a patient's eye, the patient places their head on the head fixation device 2, ensuring their eyes are directly facing the main body 3 of the measuring device. Medical personnel then adjust the main body 3 to the designated position, adjust the lighting source, and activate the lifting servo motor 8. The lifting servo motor 8 drives the ball screw 6 to rotate, which in turn moves the slider 7. The slider 7 then moves the universal joint mechanism to adjust the height of the lighting source 5. Next, the rotation servo motor 10 is activated, causing the rotating base 11 to rotate. The rotation of the rotating base 11 causes the linkage column 12 to rotate around its center. The rotation of the linkage column 12 causes the L-shaped base 13 to rotate around its center. The rotation of the L-shaped base 13 then causes the lighting base 14 to rotate, thereby activating the lighting... After the light source 5 rotates to the specified angle, the cylinder 19 is activated. The activation of the cylinder 19 drives the moving ring 18 to move, which in turn drives the outer grooved ring 17 to move. The movement of the outer grooved ring 17 drives the inner grooved ring 16 to move. The inner grooved ring 16 has an inner groove on its inner side. The ball head of the ball rod 15 is slidably installed in the inner groove. Therefore, the movement of the inner grooved ring 16 drives the ball head of the ball rod 15 to move. Since a linkage column 12 is fixedly installed on one side of the ball rod 15, the movement of the ball head drives the linkage column 12 to rotate. The rotation of the linkage column 12 drives the L-shaped base 13 to rotate, which in turn drives the lighting source 5 to move around the linkage column 12 as the center through the lighting base 14, completing the adjustment. At this time, the lighting source 5 can accurately illuminate the patient's eyes, eliminating the need for medical staff to manually make multiple adjustments.

[0030] The technological advancement of this invention compared to the prior art is that the angle of the illumination source 5 can be adjusted, allowing for more precise illumination of the patient's eyes during measurement. This eliminates the need for medical personnel to manually make multiple adjustments, greatly improving measurement efficiency and enhancing the practicality and accuracy of the equipment.
