Embodiment 1

[0032] Sclera cross-linking equipment, including the following structures:

[0033] Host 1, power cord 2; host 1 has a current regulator circuit and a control switch (this is a commonly used commercially available host structure, which will not be described in detail here);

[0034] Infusion and gas pipeline 3, used to transport gas or liquid;

[0035] It also includes an umbrella-shaped end 4; the umbrella-shaped end 4 has a hollow structure, and the umbrella-shaped end 4 includes an access surface and an output surface; the access surface is connected to the power line 2 and the infusion and gas pipeline 3 respectively; there are multiple A circular LED ultraviolet chip 5, the LED ultraviolet chip 5 is connected to the host 1 through the power line 2; the wavelength of the light source of the LED ultraviolet chip 5 is 30-450nm, and the power density is 3-90mW / cm 2 ; The diameter of the LED ultraviolet chip 5 is 3mm;

[0036] There are a plurality of isolation parts 6 on th...

Embodiment 2

[0041] Apply the sclera cross-linking device of the present invention to rabbits, pigs, and people, and the changes in the biomechanical elastic modulus are as follows: figure 1 shown.

[0042] The biomechanical properties (elastic modulus) of the sclera of rabbits, pigs, and humans were significantly improved after sclera crosslinking (P<0.05);

[0043] From attached figure 2 It can be seen that after the rabbit eyes are cross-linked using the scleral cross-linking instrument of the present invention, the progress of the axial length of the high myopia rabbit eye model is significantly slowed down (P<0.05), which proves the effectiveness of scleral cross-linking in the treatment of high myopia.

[0044] From attached image 3 It can be seen that after using the sclera cross-linking instrument of the present invention to cross-link rabbit eyes, the progression of myopia in the high myopia rabbit eye model is significantly slowed down (P<0.05), which proves the effectiveness...

Abstract

The invention belongs to the field of medical equipment, particularly relates to sclera crosslinking equipment, and further relates to a use method of the equipment. The sclera crosslinking equipmentcomprises a main machine, a power line and a conveying pipeline for conveying gas or liquid and further comprises an umbrella-shaped tail end. The umbrella-shaped tail end is of a hollow structure, and comprises an access surface and an output surface. The access surface is connected with the power line and the conveying pipeline. Multiple LED ultraviolet chips are arranged on the output surface and connected with the main machine through the power line. At least one isolation part is arranged on the output surface of the umbrella-shaped tail end, and the isolation parts are of protruding structures. The sclera is evenly covered with ultraviolet light through the evenly-distributed LED ultraviolet chips, certain distances can be kept between the LED ultraviolet chips and the surface of thesclera through the isolation parts, the sclera can be evenly covered with a riboflavin solution and oxygen, then sclera tissue is evenly and controllably crosslinked, and therefore the purpose of enhancing the rear sclera biomechanics strength clinically is achieved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a scleral cross-linking equipment, and also relates to the application of the above-mentioned equipment. Background technique [0002] High myopia is a common disease in ophthalmology. It is characterized by stretching and thinning of the sclera and elongation of the eye axis. So far, the treatment methods are extremely limited, mainly posterior scleral reinforcement, that is, suturing a layer of allogeneic sclera or Other elastic materials to strengthen the biomechanical strength of the posterior sclera and prevent further stretching of the eyeball. However, this operation has a large trauma and many complications, and the effect is still controversial in the industry. [0003] Ultraviolet cross-linking is an emerging technology developed in recent years. Studies have shown that ultraviolet cross-linking can effectively improve the biomechanical strength of the scle...
