Abstract

An embodiment of the present invention provides an aqueous humor drainage device and a manufacturing method thereof, belonging to the field of medical instruments. The aqueous humor drainage device comprises an aqueous humor dispersion disk, an intraocular drainage tube and an external drainage tube, the aqueous humor diffusing disk is located under the conjunctiva in the upper part of the eyeball, in the suprascleral region, both the intraocular drainage tube and the external drainage tube are connected with the aqueous humor diffusion disk, the input part of the intraocular drainage tube isused for communicating with the anterior chamber region or the posterior chamber region in the eye, the output part of the intraocular drainage tube is used for communicating with the input part of the external drainage tube, and the output part of the external drainage tube is used for communicating with the conjunctival region on the lower surface of the eye. The aqueous humor drainage device can improve the condition of fiber wrapping, meanwhile, the aqueous humor drainage device can still effectively drain the aqueous humor under the condition of fiber wrapping, the service life of the aqueous humor drainage device is prolonged, the structure design is reasonable, and the practicability is strong.

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. Background technique [0002] At present, the main cause of glaucoma is that the drainage of aqueous humor is blocked, which causes the increase of intraocular pressure. Therefore, controlling the intraocular pressure has become the main method for the treatment of glaucoma. In the prior art, a device for guiding the aqueous humor is implanted into the eyeball to drain the aqueous humor, thereby reducing the intraocular pressure. However, due to the stimulation of foreign matter to the tissues around the eyeball, the device for guiding the aqueous humor in the prior art is prone to fiber wrapping, which affects the normal drainage operation of the device for guiding the aqueous humor, and cannot achieve the effect of reducing intraocular pressure. The aqueous humor guiding device can be replaced with a new one, so that t...
