Abstract

This invention relates to the field of medical device technology, specifically to an easily detachable eyelid speculum for ophthalmology. It includes a support base with side plates fixedly connected to the left and right sides of the front of the support base. A limiting mechanism is fixedly installed at the top of each side plate. The limiting mechanism includes a first connecting rod hinged to the surface of the side plate. A sliding sleeve is fitted onto the surface of the first connecting rod, and a locking mechanism is fixedly installed at the top of the sliding sleeve. The locking mechanism includes a second connecting block and a second rotating sleeve. By incorporating the locking and adjusting mechanisms, this invention allows for easy removal of the eyelid speculum by rotating the first rotating sleeve during use. This rotation causes a second rotating shaft to move along its inner wall. When the second rotating shaft reaches a certain position, it disengages from the inner wall of the first rotating sleeve, facilitating the removal of the eyelid speculum and enabling individual replacement of the speculum. This also improves the disinfection rate of the eyelid speculum by staff.
