Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and relates to an eyelid retractor for auxiliary use in fundus photography examination. Background Technique

[0002] Fundus photography examination can understand the fundus conditions, screen for retinal diseases such as diabetic retinopathy, age-related macular degeneration, retinitis pigmentosa, papilledema, retinal detachment, retinal hole, macular hole, retinal artery occlusion, retinal arteriosclerosis, central retinal vein occlusion, branch retinal vein occlusion, central serous chorioretinopathy, etc., and is a common clinical treatment method. To ensure the accuracy of the examination, the patient should try to open their eyes wide and blink less. The patient's eyeball should not touch the instrument lens, otherwise it will affect the examination results and even contaminate the instrument lens, affecting the lifespan of the lens. In clinical practice, it is found that many patients do not cooperate, and the examiner must forcibly retract the patient's upper and lower eyelids with one hand and operate with the other hand. This method not only takes a long time, but also is inconvenient to operate, has a large error, and has a greater impact on the patient's examination results.

[0003] Although some eyelid retractors are disclosed in the prior art, they all have the problem of being unable to match with ophthalmic examination instruments and affecting the examination effect.

[0004] For example, Chinese Utility Model Patent Publication No. CN217118732U discloses a eye drop assistant. By installing the assistant on the eye drop bottle, the effect of opening the upper and lower eyelids can be achieved, and the patient can accurately drop the eye drops into the eyelids. However, its interface does not match the fundus photography lens at all, and the opening amplitude of the eyelids cannot be adjusted.

[0005] Another example is Chinese Utility Model Patent Publication No. CN219680684U, which discloses an adjustable eyelid retractor. The eyelid retractor is worn on the patient's face, and the driving member is used to drive the eyelid turning plate to move, so that the eyelid turning plate can open or close the eyelids. Although the opening amplitude of the eyelids can be adjusted, when the patient wears this eyelid retractor, the eyes cannot fit with the fundus camera lens either, affecting the examination effect.

[0006] For another example, in the Chinese Utility Model Patent Publication No. CN216257229U, an eyelid retractor for ophthalmic use is disclosed, which includes a lower frame. Springs are fixedly connected to both ends of the lower frame. A first telescopic rod is disposed inside the springs. The other ends of the springs are fixedly connected to the upper frame. A rotating rod is inserted through the upper part of the upper frame. A rotating shaft is sleeved on the rotating rod. A rotating plate is movably connected to the rotating shaft. A scanner is disposed on the surface of the rotating plate. A power data interface is disposed on the front surface of the upper frame. First retracting rods and second retracting rods are fixedly connected to the upper frame and the lower frame. The rod bodies of the first retracting rods and the second retracting rods that directly contact the eyelids are both semicircular arcs in terms of shape and outer surface. Although the opening amplitude of the eyelids can be adjusted, when a patient wears this eyelid retractor, it still cannot fit with the lens of the fundus camera, affecting the examination effect.

[0007] For another example, in the Chinese Utility Model Patent Publication No. CN211187176U, a portable pupil diameter measuring instrument capable of retracting the eyelids is disclosed, which includes an eyeglass frame and foldable eyeglass frames disposed on both sides of the eyeglass frame. A base block is disposed inside the eyeglass frame. An auxiliary support plate is disposed on the eyeglass frame. A camera module, an illumination system, a distance sensor, and a display screen are disposed on the base block. Although the auxiliary structure of this portable pupil diameter measuring instrument can also retract the eyelids, a light source is not required during fundus photography, so it cannot fit with the lens of the fundus camera, affecting the examination effect.

Upper telescopic fixing wheels and lower telescopic fixing wheels respectively connected to the fundus photography lens cover are disposed on the long sides of the upper eyelid retracting bracket and the lower eyelid retracting bracket. The vertical distance between the upper eyelid retracting bracket and the lower eyelid retracting bracket is adjusted through the upper telescopic fixing wheels and the lower telescopic fixing wheels. Upper support point silicone heads and lower support point silicone heads are respectively disposed at the ends of the short sides of the upper eyelid retracting bracket and the lower eyelid retracting bracket.
