Aqueous humor drainage device and manufacturing method thereof

Abstract

The invention discloses an aqueous humor drainage device and a manufacturing method thereof. The aqueous humor drainage device is in a tubular structure and comprises a tube body portion and two clamping ring portions, the wall of the tube body portion is in a porous structure, and the outer peripheral wall of the tube body portion between the two clamping ring portions is provided with a clampinggroove. When the aqueous humor drainage device is implanted, the aqueous humor drainage device can be implanted into an intraocular suprachoroidal space through an injection implanter and is clampedon the scleral spur through the clamping groove; after implantation, the hollow tube cavity of the tube body portion and the porous structure of the tube wall jointly play a role in aqueous humor drainage, and a perpetual passage of the anterior chamber and the suprachoroidal space can be formed; after the aqueous humor drainage device is implanted into the suprachoroidal space, aqueous humor canflows into the ciliary body and the suprachoroidal space through the hollow tube cavity and the porous structure of the tube wall to play a role in intraocular tension reduction and glaucoma treatment. A manufacturing process of the aqueous humor drainage device is simple, and one-time sintering forming, large-batch production and high production efficiency can be realized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an aqueous humor drainage device and a manufacturing method thereof. Background technique [0002] Glaucoma (glaucoma) is one of the major blinding eye diseases in the world. It is currently a lifelong and irreversible blinding disease, and its condition can only be delayed but not cured. Common features of patients with glaucoma are optic atrophy and visual field defect. Elevated levels of intraocular pressure and optic nerve tolerance to pressure damage are associated with the development and progression of optic atrophy and visual field defects in glaucoma. Elevated intraocular pressure (IOP) is a major risk factor for vision loss in both open-angle and closed-angle glaucoma. Lowering the intraocular pressure to the target value is currently an effective treatment to control most glaucoma diseases. [0003] Currently, the gold standard for the treatment of glaucoma disease is...

AI Technical Summary

Problems solved by technology

Schlemm's canal drainage products and choroid-scleral drainage device products are less, and the glaucoma drainage device products of the traditional choroidal-scleral route generally have the problems of complex structure and high price, and because the product size is too small, it is difficult to process It is difficult to make and the production process is cumbersome, which is not conducive to widespread application
