Flusher capable of holding upper eyelid and lower eyelid apart for ophthalmic nursing

Abstract

The invention relates to the technical field of medical instruments and discloses a flusher capable of holding the upper eyelid and the lower eyelid apart for ophthalmic nursing. The flusher comprisesa fixed rod and a movable rod; the upper end connecting rod and the lower end connecting rod are connected with first arc-shaped metal strips; the outer side of the first arc-shaped metal strip is slidably connected with an upper extrusion block; the upper end of the upper extrusion block is connected with a guide ring; the lower side of the first arc-shaped metal strip is provided with a secondarc-shaped metal strip; the second arc-shaped metal strip is connected with a lower extrusion block; the right side of a second adjusting bolt is provided with a variable resistor; and the right sideof the movable rod is provided with a metal ball. The first adjusting bolt drives the first thread and the second thread to move in the upper adjusting frame and the lower adjusting frame respectively, the sliding rod is guided to move in the sliding sleeve, the sliding rod drives the metal strips to deform and move in the same direction, the metal strips drives the upper extrusion blocks to move,and the structure solves the problem that an existing distraction device cannot evenly spread the eyelids and the eyes are prone to being injured.
