DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0031] Reference Figure 1-8 As shown, an integrated slit lamp eye detection device includes a fundus camera 13, a lateral movable component 14, a front-and-rear movable component 15, an avoidance component 16, and a slit lamp component 17. The avoidance component 16 and the slit lamp component 17 are arranged in pairs on both sides of the fundus camera 13. The fundus camera 13 is installed on the front-and-rear movable component 15. The front-and-rear movable component 15 and the avoidance component 16 are both installed on the lateral movable component 14, and move with the lateral movable component 14. The avoidance component 16 includes a fixed seat 9 installed on the lateral movable component 14, a first driving component, and a movable plate 10 movably connected to the fixed seat 9. The slit lamp component 17 is fixedly connected to the movable plate 10, and the movable plate 10 is driven by the first driving component to control the position of the slit lamp component 17 relative to the fundus camera 13 and the eye.

[0032] In actual use, when the slit lamp assembly 17 on one side is extended for inspection, the slit lamp assembly 17 on the other side retreats to avoid it. When the slit lamp assembly 17 on one side is extended for inspection, the slit lamp assembly 17 on the other side is extended for inspection to prevent interference between the slit lamp assemblies 17. The front and rear movable components 15 are used to drive the fundus camera 13 to approach or move away from the eye. When the slit lamp assemblies 17 on both sides of the fundus camera 13 are inspected, the slit lamp assemblies 17 on both sides retreat in the direction away from the eye to provide space for the fundus camera to extend for inspection. This technical solution allows the fundus camera 13 to flexibly cooperate with the slit lamp assembly 17 through the lateral movable component 14, the front and rear movable component 15, and the avoidance component 16, and avoids interference between the slit lamp assemblies 17 and the slit lamp assembly 17. At the same time, interference between the slit lamp assembly 17 and the fundus camera 13 can also be avoided. This technical solution can effectively improve the doctor's inspection efficiency.

[0033] The slit lamp assembly 17 includes a bracket 1 fixedly connected to a movable plate 10, a slit lamp 2 installed on the bracket 1, and a second driving assembly. The bracket 1 is provided with a first movable groove 11 for the slit lamp 2 to move after installation, and the first movable groove 11 is arc-shaped. The slit lamp 2 is inserted into the first movable groove 11 and is driven by the second driving assembly to move along the first movable groove 11. The slit lamp 2 is movably set in the first movable groove 11 and controlled by the second driving assembly, so that the scanning range of the slit lamp 2 can be adjusted. Compared with the traditional slit lamp assembly 17, the doctor can actively adjust the position of the slit lamp 2 to achieve a comprehensive examination of different areas of the eye.

[0034] The second driving assembly includes a second motor 3, a first nut seat 4, a first screw rod 5, and a transmission plate 6 fixedly connected to the first nut seat 4. The second motor 3 is fixedly connected to the bracket 1, the first screw rod 5 is driven by the second motor 3, the first nut seat 4 is installed on the first screw rod 5 and driven by the first screw rod 5, and the first nut seat 4 is driven by the first screw rod 5 to perform a linear reciprocating motion along the axial direction of the first screw rod 5. The transmission plate 6 is provided with a second movable groove 61 for the slit lamp 2 to penetrate at a position corresponding to the slit lamp 2, and a second movable groove 61 is provided in the second movable groove 61 for the slit lamp 2 to move back and forth. The slit lamp 2 is provided with an abutting surface 21 abutting against the inner wall of the second movable groove 61, and the transmission plate 6 is driven by the first nut seat 4 to drive the slit lamp 2 to move in the first movable groove 11. The abutting surface 21 abuts against the inner wall of the second movable groove 61 so that it can only move forward and backward in the second movable groove 61. The second movable groove 61 is reserved for the slit lamp 2 to move forward and backward, so that the transmission plate 6 will not be stuck due to interference when driving the slit lamp 2 to move. In this embodiment, the second movable groove 61 is in a waist shape, which can provide auxiliary thrust when the slit lamp 2 returns from the extreme position of the second movable groove 61.

[0035] A third movable groove 12 is provided at a position of the bracket 1 corresponding to the transmission plate 6, and the third movable groove 12 extends along the axial direction of the first screw rod 5. A vertical plate 62 extending toward the third movable groove 12 is provided at a position of the transmission plate 6 corresponding to the third movable groove 12, and the vertical plate 62 moves in the third movable groove 12 through the transmission plate 6. The purpose of setting the third movable groove 12 and the vertical plate 62 is to limit the movable stroke of the slit lamp 2. The movable stroke of the slit lamp 2 is limited by controlling the length of the third movable groove 12. In order to prevent the slit lamp 2 from exceeding the safe movable stroke, limit switches for detecting the vertical plate 62 are provided on both sides of the third movable groove 12. The limit switch is used to detect the extreme stroke of the vertical plate 62 in the third movable groove 12.

[0036] A second slider 63 is fixedly connected to the transmission plate 6, and a second guide rail 64 slidably matched with the second slider 63 is provided at a position of the bracket 1 corresponding to the second slider 63. The second guide rail 64 extends along the axial direction of the first screw rod 5, and the surfaces where the second guide rail 64 and the second slider 63 cooperate with each other are concave-convex. The second slider 63 limits the second slider 63 from detaching from the second guide rail 64 under the action of gravity through the concave-convex cooperation. The purpose of providing the second slider 63 and the second guide rail 64 is to reduce the load on the first screw rod 5 and prevent the first screw rod 5 from being deformed due to long-term pressure, thereby reducing the life of the first screw rod 5.

[0037] The slit lamp 2 is provided with an annular groove 22 at the axial section position corresponding to the first movable groove 11, and an abutting component is provided in the annular groove 22, and the abutting component includes a positioning column 23 installed in the annular groove 22 and a bearing 24 sleeved on the positioning column 23. The slit lamp 2 abuts against the inner wall of the first movable groove 11 through the outer ring of the bearing 24. In this embodiment, four groups of bearings 24 and positioning columns 23 are installed. The outer ring of the bearing 24 cooperates with the inner wall of the first movable groove 11 to reduce friction during movement, and the movement of the slit lamp 2 in the first movable groove 11 can become smooth, while the service life of the first movable groove 11 is improved. The positioning column 23 is provided with a flange to prevent the bearing 24 from falling out. The flange is provided to prevent the bearing 24 installed on the positioning column 23 from falling out, causing the slit lamp 2 to deviate from the movement trajectory. The abutting component is provided with a limiting ring 25 to prevent the slit lamp 2 from falling out of the first movable groove 11. The limiting ring 25 can make the slit lamp 2 hang on the bracket 1 and will not fall out of the first movable groove 11.

[0038] The bracket 1 is also provided with a mirror assembly, which includes a mirror base 7 and a reflector 8. The mirror base 7 is fixedly connected to the bracket 1 and corresponds to the side scanned by the slit lamp 2. The reflector 8 is tiltedly arranged on the mirror base 7. By adjusting the position of the slit lamp 2 in the first movable groove 11, the reflector 8 reflects light to different areas of the eye. In addition, the reflector 8 is arranged to cooperate with the slit lamp 2 so that there are more options for the installation position of the bracket 1, thereby better arranging the space inside the equipment.

The movable plate 10 is driven to approach or move away from the eye by the gear 103 matching the rack 102, and the gear 103 matches the rack 102 to drive the movable plate 10 to produce The movable plate 10 can move in a first direction and a second direction, wherein the first direction is a direction close to or away from the face, and the second direction is a direction close to or away from the bridge of the nose. The slit lamp assembly 17 mounted on the movable plate 10 can move toward the face and the bridge of the nose through the cooperation of the gear 103 and the rack 102. When the slit lamp assembly 17 is inspected, it is retreated in a direction away from the face and the bridge of the nose. To ensure the safe movable travel of the movable plate 10, limit switches are provided on both sides of the movable plate 10. The limit switches are used to detect the extreme position of the movable plate 10 to prevent it from exceeding the travel and causing a collision.

[0040] In actual use, when the slit lamp assembly 17 on one side is returned after the inspection is completed, the slit lamp assembly 17 on the other side is avoided, so that the patient can examine the left eye and the right eye in a single device.
