Problems solved by technology

An easy-to-disassemble eyelid opener for ophthalmology provided by the present invention has a flexible structure, can be easily disassembled, can be flexibly replaced, is convenient for disinfection, and does not need to be held by medical staff for a long time. The burden of medical staff", the device is large in size when used, it is inconvenient for medical staff to operate nearby, and it is difficult to guarantee the accuracy of the inspection results;

[0006] 3. The comparative document CN108969037A discloses a safety eyelid opener for ophthalmic examination and surgery, "including a mobilization bottom rod, a mobilization screw hole is arranged in the center of the mobilization bottom rod, a mobilization screw is inserted in the mobilization screw hole, and the bottom of the mobilization screw is connected There is a rotating rotating rod, and the surface of the rotating rotating rod is provided with anti-slip lines. Both ends of the adjusting bottom rod are movably connected with a bent eyelid opening arm through the first pin shaft. The opening angle adjustment mechanism is connected, and the top of the bent eyelid opening arm is connected to the eyelid opening rod through the easy-to-disassemble adjustment mechanism. Both are equipped with a controllable anti-drying and wetting mechanism. This device can avoid causing discomfort to the patient under the premise of ensuring the effect of eyelid opening. At the same time, it can keep the patient's eyes moist when opening the eyelid. The adjustment of the opening angle is more gentle, avoiding excessive opening of the eyelid arm and causing damage to the patient's eyes", it is difficult to adjust the inspection angle, and the effective range of the inspection cannot be guaranteed
