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 has a tubular structure, including a tube body and a snap ring, wherein the tube wall of the tube body is porous, and the outer peripheral wall of the tube body between the two snap rings fits to form a snap-in groove. groove. When the aqueous humor drainage device is implanted, it can be implanted into the suprachoroidal space of the eye through the incision of the limbus of the eye through the injection implanter, and is clamped on the scleral process through the clamping groove, and the tube after implantation The hollow lumen of the body and the porous structure of the tube wall can jointly play the role of aqueous humor drainage, and can form a permanent channel between the anterior chamber and the suprachoroidal space. After the aqueous humor drainage device is implanted in the suprachoroidal space, the aqueous humor can Through the hollow lumen and the porous structure of the tube wall, it flows into the ciliary body and the suprachoroidal space to lower intraocular pressure and treat glaucoma. The manufacturing process of the aqueous humor drainage device is simple, can be sintered and molded at one time, can be produced in large quantities, and has high production efficiency.

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
