Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a corneal cross-linking instrument. Background Art

[0002] Keratoconus and corneal ectasia are eye diseases that seriously affect vision. With the increase in corneal refractive surgeries and the improvement of diagnostic technology, the clinical incidence of these diseases is becoming increasingly higher and has become a hot topic in ophthalmic research.

[0003] Photochemical cross-linking is a treatment method that uses riboflavin (i.e., vitamin B2) as a photosensitizer in combination with ultraviolet light irradiation to treat progressive keratoconus, corneal ectasia after excimer refractive surgery, and ocular surface infections. Under normal circumstances, the corneal tension resistance of people with keratoconus will decrease by nearly 40%; and photochemical cross-linking can increase the biological "toughness" of corneal fibers by 3 times. Cross-linking can essentially enhance the physical and chemical connection between macromolecules such as fibrin, produce macromolecular polymerization, and make the target material harder. Therefore, fiber cross-linking has gradually been widely used in countries around the world and has become one of the mainstream treatments for keratoconus. In addition, the application of fiber cross-linking in corneal ectasia diseases has also been reported. Moreover, many studies have proven the efficacy of cross-linking. The treatment of eye diseases such as keratoconus and corneal ectasia can be applied to the correction of myopia, astigmatism, and presbyopia.

[0004] Existing corneal cross-linking devices use riboflavin as a photosensitizer in combination with ultraviolet (UV) light irradiation to treat progressive keratoconus and corneal ectasia. However, the light irradiation process has the following problems: (1) The size of the illumination spot cannot be adjusted. Full irradiation of the cornea will affect the state of the area without lesions, causing great discomfort to the patient, thereby affecting the treatment effect; (2) For the different illumination spot intensities required for each ring of different curvature on the cornea, it is impossible to perform differentiated irradiation to achieve precise treatment.

[0034] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The embodiment of the utility model provides a corneal cross-linking instrument, which can realize safe and effective personalized corneal cross-linking treatment.

[0036] According to an embodiment of the utility model, a corneal cross-linking device is provided, comprising:

[0037] A control host, comprising a host housing and a control module arranged in the host housing;

[0038] a support system mounted on the host housing and comprising a first support arm and a second support arm;

[0039] A display device, which is movably mounted on the host housing via the first support arm;

[0041] In this way, when corneal cross-linking treatment or processing is required, the irradiation device can be adjusted to a suitable position and angle for the cornea of ​​the eyeball through the movable second support arm, and multiple concentric annular light spots can be formed at the irradiation end through multiple light-splitting structures to perform corneal cross-linking treatment. Multiple concentric annular light spots can cover the entire roughly circular corneal area, but when performing actual corneal cross-linking, the corresponding annular light spots can be selected for irradiation according to the required corneal cross-linking area, without turning on all annular light spots for full coverage irradiation. In addition, it should be emphasized that the multiple light-splitting structures can be independent of each other, and the light source system can provide light beams of suitable light intensity to the multiple light-splitting structures at suitable power under the control of the control module, so that output light beams of suitable light intensity can be formed at the light output ends of the multiple light-splitting structures. That is to say, the light intensity of multiple annular light spots formed by multiple splitting structures at the irradiation end can be adjusted as needed to meet the needs of corneal cross-linking. This is particularly advantageous because such annular light spots with adjustable light intensity can also better adapt to the structural requirements of different annular areas on the cornea of ​​the eye (which have different curvatures), thereby facilitating the realization of intensity-differentiated irradiation treatment.
