Description

High-precision meibomian gland diagnosis and treatment instrument

Technical Field

The invention relates to the field of ophthalmic detection, in particular to a high-precision meibomian gland diagnosis and treatment instrument.

Background

Meibomian Gland Dysfunction (MGD) is a common ocular surface disease, with the most common cause of Meibomian Gland Dysfunction being the obstruction of the Meibomian Gland opening. Obstruction directly or indirectly causes changes in the quantity and quality of meibomian gland secretions, leading to instability of the tear film, the main symptom of which is manifested as dry eye.

At present, the common method for treating xerophthalmia is required to be safe, effective, simple, convenient and economical, a treatment scheme can be optimized, the side effect of treatment is reduced to the maximum extent, and the best curative effect is obtained by the minimum injury. Among them, eyelid hot compress is most commonly used; the patient can place a warm towel over the eyes, causing the meibomian glands in the eyelids to expand when heated and secrete tear fluid. However, when a patient with dry eye syndrome uses eyelid hot compress for a long time, the warm towel is in direct contact with the eyelid, so that the hidden danger that the warm towel touches and stimulates the eyeball exists, the temperature of the towel needs to be judged according to subjective feeling of the patient, when the towel is applied to the eyelid, the temperature of the part in contact with the eyelid is too low or too high, so that tear secretion or scald cannot be caused, and the treatment effect is not ideal; therefore, there is a need to design a meibomian gland diagnosis and treatment instrument with better pertinence, convenient use and good treatment effect.

The further setting is that: each filling groove and the filling medium positioned in the filling groove are in contact with one side of the ultrasonic euphotic layer so as to realize better heat transfer; and the filling groove and the filling medium positioned in the filling groove are not in contact with one side of the light-isolating layer and are insulated by the light-guiding heat-insulating layer, so that the heat energy released by the filling medium is prevented from being transferred to the light-isolating layer.

The further setting is that: the membrane unit consists of a straight line section and a bending section which are connected, wherein the inner side of the bending section is attached to the surface of the cornea, and the outer side of the bending section is attached to the inner surface of the eyelid; the filling grooves are uniformly distributed on the bending section part of the light guide and heat insulation layer.

The invention has the beneficial effects that:

1. after the membrane unit is stretched into the inner side of an eyelid, an ultrasonic probe is aligned to the position of the eyelid to be treated to emit ultrasonic waves through a handheld ultrasonic host, an ultrasonoscope sequentially penetrates through an ultrasonic euphotic layer and a light guide and heat insulation layer, and a filling medium in the light guide and heat insulation layer is converted under the action of the ultrasonic waves and releases heat energy, so that meibomian glands in the eyelid are stimulated to expand by heating to secrete tear water; the eyelid treatment of the patient is simply and effectively realized, the pertinence is better, the eyelid position of the patient can be accurately aligned for treatment, the temperature can be set through the ultrasonic frequency of the ultrasonic host, the temperature can be controlled and stable, and the eyelid treatment effect is better.

2. In the invention, the heat energy is released by arranging the filling medium in the light guide heat insulation layer, so that the inner layer of the eyelid can be treated on the inner side of the eyelid, and the meibomian gland in the eyelid is stimulated to expand by heating more quickly and effectively to secrete tear water, thereby achieving the purpose of treating xerophthalmia; clearly, the effect is better than that of the eyelid hot compress method on the outer side of the eyelid.

3. The invention also considers the problem of how to protect the cornea, sclera and iris after optimizing the treatment effect. Therefore, the light guide and heat insulation layer and the light isolation layer are arranged in the cornea-filled heat insulation device, and the light guide and heat insulation layer can effectively insulate heat to prevent heat released by the filling medium from being directly transferred to the cornea; the light-isolating layer can effectively isolate the ultrasound, and the ultrasound is prevented from penetrating through the light-isolating layer to influence the cornea; therefore, the invention can achieve the purpose of safety and reliability in actual use.

4. In the invention, the infrared imaging sensor is arranged to effectively capture the image of the eyelid, so that more accurate positioning treatment is realized by matching with an ultrasonic host, which is not possessed by large-area treatment adopted by the traditional eyelid hot compress method.
