A safety eyelid speculum for ophthalmic examination and operation

Abstract

The invention discloses a safe eyelid speculum for ophthalmic examination and operation. The safe eyelid speculum comprises a base mobilization bar, a mobilization screw hole is arranged in the centerof the base mobilization bar, a mobilization screw is inserted in the mobilization in the mobilization screw hole, a rotary turn lever is connected to the bottom of the mobilization screw, an anti-skid stripe is arranged on the surface of the rotary turn lever, each of two ends of the base mobilization bar is movably connected with a bending eyelid opening arm through a first pin shaft, the bending eyelid opening arms and the mobilization screws are connected through a total opening angle adjusting mechanism, the top of each bending eyelid opening arm is connected with a eyelid opening rod through a convenient-removal adjustment mechanism, the inner side of each eyelid opening rod is connected with a bearing piece, one side of the bearing piece is connected with a three-point eyelid opening mechanism, and the top of the bearing piece is provided with a controllable anti-drying wetting mechanism. The safe eyelid speculum can ensure the effect of eyelid opening and avoid discomfort of patients, and meanwhile, patients' eyes can be kept moist during eyelid opening; in addition, the opening angle of the eyelid opening arms can be more gentle, and excessive opening of the eyelid opening arms, which causes damage to the patients' eyes is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a safety eyelid speculum for ophthalmic examination and operation. Background technique [0002] The full name of ophthalmology is "eye disease specialist", which is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies vitreous, retinal diseases, optometry, glaucoma and optic neuropathy, cataract and other ophthalmic diseases. Common eye diseases include: central serous retinopathy, dry eye, sympathetic ophthalmia, night blindness, blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, heterochromia, retina Pigmentary degeneration, central retinal artery occlusion, retinal detachment, myopia, hyperopia, needle eye, snow blindness, chalazion, glaucoma, floaters, etc. [0003] The eyelid speculum is often used in eye e...

AI Technical Summary

Problems solved by technology

[0008] (1) Most of the existing eyelid openers open the eyelids at a single point or in a linear manner, but the single-point opening of the eyelids will increase the force on the eyelids, which is likely to cause discomfort to the patient, and the linear expansion of the eyelids will either cause Cause tearing pain at the corner of the eye, or make the eyelid opening effect not good;

[0009] (2) When the existing eyelid opener stretches the eyelids, it will inevitably cause the dryness of the patient's eyes, so that the patient will turn the eyeballs due to discomfort, which is not conducive to the doctor's inspection or operation;

[0010] (3) The existing method of eyelid opener to adjust the opening angle of the eyelid opening arm is usually to manually rotate the eyelid opening arm, or use a spring or other structure to automatically open the eyelid opening arm, but this method is difficult to effectively control , it is easy to cause excessive opening of the eyelid arm, causing damage to the patient's eyes
