Description

Eye external muscle training device for vision rehabilitation

Technical Field

The invention relates to the field of vision recovery devices, in particular to an extraocular muscle training device for vision rehabilitation.

Background

The extraocular muscles (extraocular muscles) are muscles attached to the outside of the eyeball and are named opposite to the intraocular muscles (ciliary muscles, mydriasis and sphincter muscles), the extraocular muscles are striated muscles which are used for the movement of the eyeball, each eye has 6 muscles, each eye is divided into a rectus muscle and an oblique muscle according to the walking direction of the eye, and 4 rectus muscles are upper, lower, inner and outer rectus muscles; the two oblique muscles are the superior oblique muscle and the inferior oblique muscle, the four rectus muscles all start from the total tendon ring around the optic nerve foramen at the apex of the orbit, the muscle fiber of each muscle is bundled to surround the optic nerve and is spread forwards respectively, and is attached to the sclera in front of the equator of the eyeball and at different distances from the limbus of the cornea, the inner, lower, outer and superior rectus muscles are attached to the positions 5.5mm, 6.5mm, 6.9mm and 7.7mm behind the limbus respectively, the superior oblique muscle also starts from the total tendon ring and advances along the intersection angle of the superior wall of the orbit and the inner wall of the orbit, becomes a tendon near the upper medial border of the orbit, passes through the annulus fibrosus of the pulley, then turns posteriorly and laterally past the inferior aspect of the rectus superior muscle to the posterior aspect of the equator of the eyeball, attaches to the superior posterior aspect of the eyeball, the inferior oblique muscle originates from the inferior medial aspect of the orbital wall, then, the blood passes between the inferior rectus muscle and the inferior wall of the orbit, extends outward to the back of the equator of the eyeball, adheres to the posterior and lateral side of the eyeball, and the blood of the extraocular muscle is supplied by the muscular branch of the ophthalmic artery.

With the development of science and technology, electronic products such as mobile phones and computers become an indispensable part of people's office work and life gradually, and long-term use of the electronic products can cause oppression to eyes, lead to insufficient blood supply and dry eyes, and then induce inflammation and infection. Meanwhile, long-time watching of mobile phones and computers causes that muscles of eyes of people cannot be trained and extended, so that a series of eye diseases such as myopia, strabismus, astigmatism and the like are caused. Some mild ocular diseases can be recovered by rehabilitation training treatments.

Eye muscle is taken exercise and can be alleviated eye pressure, reaches rehabilitation training's effect, and current rehabilitation training generally lets the patient watch the green vegetation in distance, lets eye muscle obtain the extension, but the training efficiency of this kind of mode is lower, and then has delayed the training progress.

To solve the above problems, we propose an extraocular muscle training device for vision rehabilitation.
