Detailed implementation manners

[0030] The following will further elaborate on the present invention in conjunction with the embodiments shown in the accompanying drawings.

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

[0032] In actual use, when the slit lamp assembly 17 on one side extends for inspection, the slit lamp assembly 17 on the other side retracts to make way. After the inspection by the slit lamp assembly 17 on one side is completed, the slit lamp assembly on the other side extends for inspection to prevent interference between the slit lamp assemblies 17. The front-back moving assembly 15 is used to drive the fundus camera 13 closer to or farther from the eye. After the inspection of the slit lamp assemblies 17 on both sides of the fundus camera 13 is completed, the slit lamp assemblies 17 on both sides retract in a direction away from the eye to provide space for the fundus camera to extend for inspection. This technical solution enables the flexible cooperation between the fundus camera 13 and the slit lamp assemblies 17 through the lateral moving assembly 14, the front-back moving assembly 15, and the avoidance assembly 16, and avoids interference between the slit lamp assemblies 17 and also between the slit lamp assemblies 17 and the fundus camera 13. This technical solution can effectively improve the doctor's inspection efficiency.

[0033] The slit lamp assembly 17 includes a bracket 1 fixedly connected to the 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 slot 11 for the slit lamp 2 to move after installation. The first movable slot 11 is arc-shaped. The slit lamp 2 is inserted into the first movable slot 11 and is driven to move along the first movable slot 11 in the first movable slot 11 by the second driving assembly. By movably arranging the slit lamp 2 in the first movable slot 11 and controlling it through the second driving assembly, 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 inspection of different areas of the eye.

[0034] The second driving assembly includes a second motor 3, a first nut seat 4, a first lead screw 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 lead screw 5 is driven by the second motor 3. The first nut seat 4 is installed on the first lead screw 5 and is driven by the first lead screw 5. The first nut seat 4 can perform a linear reciprocating motion along the axial direction of the first lead screw 5 under the drive of the first lead screw 5. The transmission plate 6 is provided with a second movable slot 61 corresponding to the position of the slit lamp 2 for the slit lamp 2 to pass through. There is a space for the slit lamp 2 to move back and forth in the second movable slot 61. The slit lamp 2 is provided with a contact surface 21 that abuts against the inner wall of the second movable slot 61. The transmission plate 6 drives the slit lamp 2 to move in the first movable slot 11 through the first nut seat 4. The contact surface 21 abuts against the inner wall of the second movable slot 61 so that it can only move back and forth in the second movable slot 61. The space reserved for the slit lamp 2 to move back and forth in the second movable slot 61 prevents the transmission plate 6 from getting stuck due to interference when driving the slit lamp 2 to move. In this embodiment, the shape of the second movable slot 61 is waist-shaped, which can provide an auxiliary thrust when the slit lamp 2 returns from the limit position of the second movable slot 61.

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

[0036] A second slider 63 is fixedly connected to the transmission plate 6. A second guide rail 64 slidably matched with the second slider 63 is provided at the position of the bracket 1 corresponding to the second slider 63. The second guide rail 64 extends along the axial direction of the first lead screw 5. The mating surface between the second guide rail 64 and the second slider 63 is a concave-convex fit. The second slider 63 is restricted from disengaging from the second guide rail 64 under the action of gravity through the concave-convex fit. The purpose of setting the second slider 63 and the second guide rail 64 is to reduce the load on the first lead screw 5 and prevent the first lead screw 5 from deforming due to long-term compression, resulting in a reduction in the service life of the first lead screw 5.

[0037] An annular groove 22 is provided at the shaft section position of the slit lamp 2 corresponding to the first moving groove 11. An abutting member is provided in the annular groove 22. The abutting member includes a positioning post 23 installed in the annular groove 22 and a bearing 24 sleeved on the positioning post 23. The slit lamp 2 abuts against the inner wall of the first moving groove 11 through the outer ring of the bearing 24. In this embodiment, four groups of bearings 24 and positioning posts 23 are installed. By matching the outer ring of the bearing 24 with the inner wall of the first moving groove 11, the friction during movement can be reduced, and the movement of the slit lamp 2 in the first moving groove 11 can become smooth. At the same time, the service life of the first moving groove 11 is increased. A flange for preventing the bearing 24 from slipping off is provided on the positioning post 23. The flange is provided to prevent the bearing 24 installed on the positioning post 23 from falling out, resulting in the slit lamp 2 deviating from the movement track. A limiting ring 25 for preventing the slit lamp 2 from falling out of the first moving groove 11 is provided on the abutting member. The limiting ring 25 can make the slit lamp 2 hang on the bracket 1 and not fall out of the first moving groove 11.

[0038] The bracket 1 is further 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 inclined on the mirror base 7. By adjusting the position of the slit lamp 2 in the first movable slot 11, the reflector 8 reflects light to different areas of the eye, and the installation position of the bracket 1 can have more choices by setting the reflector 8 cooperating with the slit lamp 2, so as to better layout the space inside the device.

[0039] The first driving assembly includes a first motor 101 installed on the fixed seat 9 and a rack 102 installed on the movable plate 10. A gear 103 meshing with the rack 102 is provided on the output shaft of the first motor 101. A second guide rail 64 is provided on the fixed seat 9, and a second slider 63 engaging with the second guide rail 64 in a concave-convex manner is provided on the movable plate 10. The second slider 63 restricts the gear 103 from disengaging from the rack 102 through the concave-convex fit. The movable plate 10 is driven to approach or move away from the eye through the cooperation of the gear 103 and the rack 102. The cooperation of the gear 103 and the rack 102 drives the movable plate 10 to move in a first direction and a second direction. The first direction is the direction of approaching or moving away from the human face, and the second direction is the direction of approaching or moving away from the nose bridge. The slit lamp assembly 17 installed on the movable plate 10 can approach the human face and the nose bridge through the cooperation of the gear 103 and the rack 102. After the inspection of the slit lamp assembly 17 is completed, it retreats in the direction away from the human face and the nose bridge. To ensure the safe movement stroke of the movable plate 10, limit switches are respectively provided on both sides of the movable plate 10 for detecting the extreme positions of the movable plate 10 to prevent it from exceeding the stroke and causing collisions.

[0040] In actual use, when the inspection of the slit lamp assembly 17 on one side is completed and it retreats to make way for the slit lamp assembly 17 on the other side, so that the patient can have the left eye and the right eye examined in a single device. In this solution, to further ensure the stability of the movable plate 10, a third guide rail 93 is provided on the fixed seat 9, and a third slider 94 engaging with the third guide rail 93 in a concave-convex manner is provided on the movable plate 10. The third slider 94 restricts the third slider 94 from disengaging from the third guide rail 93 under the action of gravity through the concave-convex fit. Through the cooperation of the two groups of guide rails and sliders, the movable plate 10 can move smoothly on the guide rail. In this solution, an infrared supplementary light 104 is also provided on the movable plate 10.
