Description

Technical Field

[0001] The utility model relates to the technical field of eyelid openers, in particular to an adjustable eyelid opener. Background Art

[0002] The working principle of the eyelid speculum is similar to that of the retractor, an essential tool in surgical operations. The product itself is the retractor used in ophthalmic surgery. It is called an eyelid speculum because it supports the production of the eyelids during ophthalmic surgery.

[0003] Through patent search, it was found that the adjustable eyelid opener with publication number CN219354005U can control the movement of the connecting frame and the eyelid hook through the elastic force of the spring, thereby achieving a stable eyelid opening effect on the patient's eyes, fully exposing the surgical field of view, and cooperating with the spring and the connecting rod to open the eyelids. At the same time, the moderate elasticity of the spring itself is fully utilized to adjust autonomously with the size of the eyelid palpebral fissure and the eyelid tension, thereby increasing / decreasing the size of the eyelid opening, and has a certain personalized practicality. The above-mentioned comparative document requires the use of a limit pin inserted into the limit hole to complete the adjustment of the distance between the two sets of eye hooks, which has a certain inconvenience in operation.
