Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an eyelid stretching device. Background Art

[0002] An eyelid stretcher is a commonly used medical device used to stretch the upper and lower eyelids of patients when they undergo ophthalmic surgery or other treatments. It consists of two separate brackets that can fix the upper and lower eyelids in appropriate positions. This device is often used in fundus surgery, corneal transplantation, cataract surgery and other ophthalmic surgeries. It can provide doctors with a better field of view to ensure the stability and operability of the surgical area. It is an indispensable medical auxiliary device in ophthalmic surgery. However, the existing eyelid stretcher lacks a fixing device and usually requires an assistant physician to hold it so that the surgeon can free up both hands for surgical operations. This is not convenient and affects the efficiency of the surgical work. Moreover, when the eyelid opening part on the eyelid stretcher is damaged, it can only be discarded, which is very unfavorable for the control of medical costs. For this reason, we propose an eyelid stretcher to solve the above problems. Utility Model Content
