Device for treating disease of cornea tissue

Abstract

The device of treating disease of cornea tissue comprises central processing unit; laser group including UV-light laser and green-light laser, both of which are set in parallel into dual light source system; adjustable optical element group, which makes the light resources of laser group reach the expected effect of cross-linking reaction on the irradiated surface in accordance with the set pattern; sealed cavity, inside of which there sets adsorbing ring for adsorbing the skin surrounding the ocular tissue for purpose of fixing the operated eye; oxygen supply device, for conveying oxygen into the sealed cavity; solution instilling absorption device, for import the medicine containing photosensitizer to the surface of operated eye, and the ingredient of photosensitizer is proportionally-mixed riboflavin and rosebengal; measuring system, for real-time observation on the treatment status of the cornea, and transmitting the observed results to the central processing unit for processing. The device can greatly improve the effect of treating the disease of cornea tissue and the efficiency of treatment.

Description

technical field [0001] The invention relates to medical equipment for treating eye diseases, in particular to a device for treating corneal tissue diseases. Background technique [0002] Keratoconus is an ophthalmic disease characterized by dilated cornea with central thinning and protruding forward, conical shape. It can be unilateral or bilateral, usually adolescence is the stage of high incidence, and it generally stops developing between the ages of 30 and 40. Its incidence rate is about 0.05%. It can cause refractive errors in patients, and in severe cases, vision damage. Since the 1990s, the technology of irradiating photosensitizers such as riboflavin with ultraviolet light, which can promote tissue cross-linking, has been applied to the treatment of keratoconus, which has greatly improved the effect of treating this disease. [0003] However, traditional treatment instruments and treatment methods cannot systematically and comprehensively refine the treatment proc...

AI Technical Summary

Problems solved by technology

[0003] However, traditional treatment instruments and treatment methods cannot systematically and comprehensively refine the treatment process, and there are mainly the following problems:

[0004] 1. The control of the laser is too simple, and the long-term unchanged irradiation cannot achieve the expected effect of cross-linking

[0005] 2. The choice of laser light source is too single, and other visible light cannot be introduced into the treatment, so as to reduce the harm to patients and doctors during treatment

[0006] 3. For corneal thickness less than 400μm, it cannot be treated directly, and direct irradiation will cause damage to eye tissue

[0007] 4. For the introduction of drugs, the traditional syringe dripping method does not absorb the drugs very well, and lacks control over the oxygen concentration and temperature of the surrounding environment

[0008] 5. There cannot be a simple and feasible real-time observation method for corneal treatment status

[0009] 6. The established system and data are not complete enough, and there is a lack of individualized treatment plans designed and implemented for different patients during the treatment process
