Description

The myopia Corrective instrument

Technical field: this utility model belongs to medical instruments field, relates to a kind of near-sighted Corrective instrument.

Background technology: myopia is because the disease that ametropia causes mainly shows as visual deterioration.A tree name medical literature record, its pathogenesis basis are that change such as the cornea that causes of multiple reason, crystalline lens, axial length of the eye cause due to the refractive power enhancing.Can reach the therapeutic purposes that improve vision if change three's one.Medical circle is explored the Therapeutic Method of myopia always for many years.Totally be divided into traumatic treatment and non-invasive treatment two big classes.What traumatic treatment was commonly used has: radial keratotomy operation (RK) and excimer laser corneal ablation operation (PRK) and other refraction correction surgery.What non-invasive treatment was commonly used has: pharmacotherapy, electrotherapy, magnetic therapy, acupuncture of a point massotherapy and eyeglass therapy etc.Corneal orthopedics art (OK mirror) in addition in vogue in the world in recent years.Cut both ways at aspects such as curative effect, side effect, complication, sequela repetitive therapy.Have at present 70% teenager to be subjected to the puzzlement of myopia approximately, they need a kind of safe and effective and convenient and reliable treatment means.

Summary of the invention: this utility model is in order to solve problems such as the side effect that exists in the existing therapy, complication, sequela, a kind of near-sighted Corrective instrument is proposed, it is characterized in that: described Corrective instrument left-right symmetric, mainly form by fixture, orthosis, compressing apparatus for adjusting force, two fixtures connect the interpupillary distance adjustment sheet by the nasion one side about described, and the outside is connected by fixing band; The inboard that described orthosis is positioned at described fixture contacts with eye, is connected with the described compressing apparatus for adjusting force that passes described fixture locating hole.This therapeutic instrument is the non-invasive treatment apparatus, treats myopia under the situation of catacleisis, eyeball can not take place infect, and patient does not have discomfort, and instrument is regulated easily, but repetitive therapy, stable curative effect, expense is low.

Fig. 2, the partial structurtes sketch map of this utility model myopia Corrective instrument;

Fig. 3, the A-A cutaway view of the partial structurtes sketch map of this utility model myopia Corrective instrument.

The specific embodiment: as shown in Figure 1 and Figure 2, the structure and the eyes of this myopia Corrective instrument adapt, and the structure left-right symmetric mainly is made up of fixture 1, orthosis 5, compressing draught control system etc.About be to connect between two fixtures 1 by interpupillary distance adjustment sheet 3 by the nasion one side, can regulate orthosis 5 spacings, to adapt to patient's interpupillary distance difference; The outside of the Corrective instrument of right and left eyes connects with elastic band 4, forms ring-type, is fixed in head, strengthens the stability that Corrective instrument and eye are fitted.There is cylinder locating hole 7 in fixture 1 central authorities, be set to arc with the one side of eye contact, take true man's delivery, digital scanning, laser to take a picture and design, the machine-shaping of digital control lathe processing technology, can adapt to the numerous change of shape in human eye position, comfort is arranged when patient uses.The inboard that orthosis 5 is positioned at fixture 1 contacts with eye, and with the curved surface of eye contact surface for adapting with eyeball, its opposite face is the female thread opening, projection 12 is cylindrical, with the mode that is threaded with oppress apparatus for adjusting force and be connected.The compressing apparatus for adjusting force form by spring or rubber spring 11, screw rod 9 and stop collar 10, stop collar 10 is the cylinder of hollow, it is spacing to be used for spring 11, and with screw rod 9 matched in clearance, screw rod 9 can move freely vertically; The locating hole 7 of stop collar 10 and fixture 1 is connected by threaded engagement, and can before and after regulate; Screw rod 9 passes stop collar 10 and is connected with orthosis 5, and the spring 11 that will be socketed on the cylinder 12 is pressed between orthosis 5 and the stop collar 10, make the orthosis 5 and the inner face of fixture 1 be positioned at same curved surface, and orthosis 5 can be moved vertically, decline pressure by spring 11 effect formation, this pressure conducts to cornea through eye part skin and plays moulding effect, changes its diopter, improves vision.Outwards simultaneously be connected with stop collar 10 in fixture 1 by outer housing 2.In order to improve therapeutic effect, fixture 1 is provided with a plurality of commode windows 6 corresponding with the eye acupuncture point, as cave, Tongzi point, Qiuhou acupoint, tip of the brow cave etc. in Jingming acupoint, the eyebrow.When fixture 1 is fixed in when preocular, the thrust that commode window 6 is placed can apply massage to above-mentioned acupuncture point to stimulate; As in show window, placing the Chinese herbal medicine of sensible active, refreshment eyesight improving, the liver-fire that clears away heart-fire, make medicinal effectiveness slowly be released on the acupuncture point; Of a specified duration then can improve the spasm of accommodation that eyestrain causes, thereby reaches the purpose that reduces diopter, improves vision.

The principle of this therapeutic instrument for shortsightedness utilization is: by improving corneal curvature, shorten axial length of the eye, make meridians in order, loosen adjusting.Specifically be eyeball to be applied certain pressure, continue the regular hour, corneal curvature radius prolongation, axial length of the eye are shortened, reach and reduce near-sighted diopter, improve the purpose of vision by orthotic device.During use, elder generation checks, patient's eye related data, and each parts of near-sighted Corrective instrument are transferred to the optimum position, be fixed in preocular after patient's eyes closure, continue eye is applied suitable pressure by orthosis then, simultaneously the acupuncture point of circumference of eyes is stimulated or acupoint stimulation adds the medicine effect,, improve the purpose of vision to reach the minimizing diopter.

Because this myopia Corrective instrument is the non-invasive treatment apparatus, treats myopia under the situation of catacleisis, eyeball can not take place to be infected, patient does not have discomfort, and instrument is regulated easily, but repetitive therapy, stable curative effect, expense is low.
