Eyelid retractor capable of fixing eyeball and application thereof

Abstract

The invention provides a lid speculum capable of fixing the eyeball, which comprises a C-shaped body part (1) and two arm parts (2), and parts (3) which can be fixed on the skin are glued to the ends of the upper and lower two arm parts ), wherein the inner diameter of the ring of the C-shaped body (1) is equivalent to the diameter of the adult cornea, and the basal surface of the C-shaped body (1) is in an arc matching the conjunctival sac. The C-shaped body (1) of the eyelid opener can be stuck on the corneoscleral limbus, thereby achieving the purpose of fixing the eyeball. The eyelid speculum can be used in ophthalmic surgery and / or ophthalmic examinations that require the patient to keep their eyes wide open and fixate, such as for anterior puncture, anterior segment laser surgery, optical coherence tomography (OCT) examination, Heidelberg retinal tomography Scan (HRT) examination, optic nerve fiber thickness analysis (GDx) or corneal endothelial count.

Description

technical field [0001] The invention relates to an ophthalmic medical device, in particular to a lid speculum capable of fixing the eyeball. Background technique [0002] The eyelid speculum is a very important auxiliary device in the process of ophthalmic treatment and diagnosis. Its function is to help the doctor to open the patient's eyelid, which is convenient for the doctor to operate. However, the current eyelid speculum has simple functions and cannot fully meet the needs of eye examination, treatment and surgery. [0003] For example, anterior chamber puncture is a basic treatment in ophthalmology, and it is an important and effective method for treating acute eye diseases such as acute angle-closure glaucoma attack and retinal artery occlusion. At present, the traditional method of anterior chamber puncture is to use a conventional eyelid speculum to open the eyelids, and to puncture the anterior chamber with a puncture needle under a microscope. However, the movem...

AI Technical Summary

Problems solved by technology

At present, the traditional method of anterior chamber puncture is to use a conventional eyelid speculum to open the eyelids, and to puncture the anterior chamber with a puncture needle under a microscope. However, at this time, the movement of the patient's eyeballs is not easy to control, and the iris or lens will be stabbed if there is a slight carelessness. Cause serious complications such as iris injury or traumatic cataract, therefore, anterior chamber puncture requires high technical level of physicians

These limit the scope of application of this technology, especially in primary hospitals, which may delay the timing of treatment for patients
