Novel adjustable eye speculum for children for ophthalmology department

Abstract

The invention discloses a novel adjustable eye speculum for children for the ophthalmology department, and particularly relates to the field of eye speculums. The eye speculum comprises a fixing strip, a locating assembly is fixedly connected with the surface of the fixing strip, and adjusting assemblies are arranged at the two ends of the fixing strip; eyelid expanding assemblies are fixedly connected with the front surfaces of the adjusting assemblies, and eyelid expanding hooks are arranged at the right ends of the eyelid expanding assemblies. Firstly, a pillow sleeves the head fixing stripof a patient, mutual cooperation among the fixing strip, an adjusting plate, a movable block, a pressing plate and a twisting block is utilized for adjustment, then the eyelid of the patient is fixedby the eyelid expanding hooks, a second threaded rod is slowly rotated, so that the second threaded rod drives a first piston to move rightward in a piston cylinder and extrude liquid in the piston cylinder, so that a second piston and piston rods are away from the horizontal center line of the piston cylinder, the two eyelid expanding hooks can be stably driven to move reversely through the fourpiston rods, and therefore it is avoided that in the eyelid expanding process, the angle difference is formed.
