Specific application example 7:

referring to fig. 13, an eyelid retractor includes: the opening bracket 100, the eyelid hook 200, and the eyelid portion 300, the opening bracket 100 having a first tension arm 400 and a second tension arm 500, the eyelid hook 200 comprising: the back hook support 210, the first back hook 220 and the second back hook 230, the back hook support 210 is connected with the tail end of the first tension arm 400, the first back hook 220 is arranged at one end of the back hook support 210, the first back hook 220 is used for being abutted against the eyelid turning body 310, the second back hook 230 is arranged at one end of the back hook support 210 far away from the first back hook 220, and the second back hook 230 is used for being abutted against the eyelid turning body to clamp the eyelid to enable the eyelid to be turned. The difference between this embodiment and the specific application embodiment 6 is that: the first swing arm 160 is provided with a first threaded interface 161, and the first tension arm 400 is detachably connected with the first threaded interface 161 through threads. The second swing arm 170 is provided with a second threaded interface 171, and the second tension arm 500 is detachably connected with the second threaded interface 171 through threads.

In this embodiment, the first tension arm 400 is detachably connected with the first threaded interface 161 through threads, that is, the first tension arm 400 can be detached through the first threaded interface 161 to replace different eyelid hooks 200, for example, eyelid hooks 200 with different specifications can be replaced, or after the eyelid hooks 200 are damaged, only the eyelid hooks 200 need to be replaced, and the whole scrapped replacement is not needed, which is beneficial to saving the equipment cost.

In summary, the present application discloses a eyelid retractor, wherein the eyelid retractor includes: the eyelid hook is arranged at the tail end of the first tension arm, and the eyelid turning part is arranged at the tail end of the second tension arm. The arc eyelid edge and the curled edge in the eyelid turning part can increase the contact area with eyelid skin, can improve the comfort level when the eyelid is lifted, simplifies the operation and improves the safety.

The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
