[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in FIG. 3 , in this embodiment, an image enhancement device for a fundus camera is proposed, comprising a support structure installed at the lower end of a portable fundus camera 1, a fixed handle 2 and a movable handle 3 are provided at the lower end of the portable fundus camera 1, the fixed handle 2 is fixedly connected to the portable fundus camera 1, and the upper end of the movable handle 3 is hinged to the portable fundus camera 1 through a pivot;

[0024] When performing ophthalmic diagnosis, the doctor can operate the portable fundus camera 1 with one hand by holding the fixed handle 2. The captured image data is transmitted to the processing unit, digitized to optimize the image quality, and then displayed on the display screen for the doctor's analysis.

[0025] Specifically, the support structure includes a mounting seat 5, the upper end of the mounting seat 5 is detachably connected to the lower end of the movable handle 3, and the lower end of the mounting seat 5 has at least three legs 7, each leg 7 surrounds the mounting seat 5, the upper end of the leg 7 is hinged to the first hinge seat 4 fixedly connected to the outer side of the mounting seat 5, and the lower end of the leg 7 is provided with an anti-slip structure; the portable fundus camera 1 is mounted on the upper end of the mounting seat 5 through the movable handle 3, and each leg 7 supports the portable fundus camera 1 through the mounting seat 5, freeing the user's hands while the open legs 7 can ensure that the portable fundus camera 1 is stable and shake-free during shooting, which can significantly improve the clarity of the image. In addition, the detachable connection between the movable handle 3 and the mounting seat 5 also makes it convenient for the staff to disassemble the support structure and the portable fundus camera 1 and carry them separately, which is very convenient.

[0026] In order to prevent the fixing cylinder 6 at the lower end of the mounting seat 5 from spreading out when the mounting seat 5 is carried after being folded, a clamping sleeve structure for limiting the legs 7 in the folded state is provided at the lower end of the mounting seat 5. After each leg 7 is folded, the clamping sleeve structure will limit each leg 7.

[0027] Specifically, the clamping sleeve structure includes a positioning column 9, which is fixedly connected to the lower end of the mounting seat 5. At least three rubber clips 11 are provided at the lower end of the positioning column 9. Each rubber clip 11 surrounds the positioning column 9 and is fixedly connected to the positioning column 9. Each rubber clip 11 corresponds to each leg 7. The rubber clip 11 faces the side of the leg 7 and is provided with a clip groove 12 for plugging and matching with the leg 7. After the legs 7 around the mounting seat 5 are folded, the legs 7 will move closer to the rubber clip 11 at the lower end of the positioning column 9 until they are pushed into the clip groove 12 provided on the rubber clip 11. The clip groove 12 prevents the legs 7 from spreading out by damping contact with the legs 7.

[0028] In the method of fixing the leg 7 simply by the damping between the rubber clip 11 and the leg 7, the leg 7 still has the problem of slipping out of the clamping groove 12 on the rubber clip 11 during the process of carrying the support structure. In the preferred solution, the upper end of the leg 7 is provided with a clamping edge 8, and the clamping edge 8 is placed on both sides of the leg 7. After the leg 7 is inserted into the clamping groove 12, the clamping edge 8 is engaged with the rib groove 14 provided on the inner side of the clamping groove 12. The rib groove 14 further limits the leg 7 by cooperating with the clamping edge 8, thereby preventing the leg 7 from being separated from the clamping groove 12 and improving the stability during carrying. The buckle matching method does not affect the normal deployment of each leg 7.

[0029] Regarding the detachable connection between the movable handle 3 and the mounting seat 5, a threaded column is provided at the lower end of the movable handle 3, and a fixed cylinder 6 is provided at the upper end of the mounting seat 5. The threaded column is fixedly connected to the movable handle 3, and the fixed cylinder 6 is fixedly connected to the mounting seat 5. The threaded column is threadedly connected to a threaded hole 13 provided at the upper end of the fixed cylinder 6. The movable handle 3 and the mounting seat 5 are fixed by threaded connection. When the portable fundus camera 1 is removed from the upper end of the mounting seat 5, the threaded column at the lower end of the movable handle 3 can be screwed out of the threaded hole 13, which is convenient for disassembly and replacement.

[0030] Regarding the anti-skid structure: the anti-skid structure includes a rubber block 10, a second hinge seat 15 is disposed at the upper end of the rubber block 10, the second hinge seat 15 is fixedly connected to the rubber block 10, and the upper end of the second hinge seat 15 is hinged to the lower end of the leg 7 through a pivot. The rubber block 10 plays an anti-skid role, which can improve the stability of the leg 7 when it is on a smooth ground or table, and prevent the portable fundus camera 1 from deviating during shooting.

[0031] It should be noted that the connection between the second articulated seat 15 and the leg 7, the movable handle 3 and the portable fundus camera 1, and the leg 7 and the first articulated seat 4 is provided with a butterfly spring for increasing the damping of the connection between the second articulated seat 15 and the leg 7, the movable handle 3 and the portable fundus camera 1, and the leg 7 and the first articulated seat 4. This is to prevent the movable handle 3, the leg 7, and the second articulated seat 15 from rotating arbitrarily, affecting the support structure and the stable shooting of the portable fundus camera 1. Of course, in addition to the butterfly spring, a damping structure such as a rubber ring can also be used as an alternative, which will not be explained in detail here.

[0032] In order to improve the hand-held comfort of the portable fundus camera 1 , rubber sleeves 16 are sleeved on the outer sides of the fixed handle 2 and the movable handle 3 .

[0033] Working principle of the present application: The doctor can hold the fixed handle 2 to operate the portable fundus camera 1 with one hand. The captured image data is transmitted to the processing unit, digitized to optimize the image quality, and then displayed on the display screen for the doctor's analysis. The portable fundus camera 1 is mounted on the upper end of the mounting seat 5 via the movable handle 3, and each leg 7 supports the portable fundus camera 1 via the mounting seat 5. While freeing the user's hands, the open legs 7 can ensure that the portable fundus camera 1 is stable and shake-free during shooting, which can significantly improve the clarity of the image. In addition, the detachable connection between the movable handle 3 and the mounting seat 5 also makes it convenient for the staff to disassemble the bracket structure from the portable fundus camera 1 and carry them separately, which is very convenient.
