Abstract

The invention provides a glaucoma drainage device, and relates to the technical field of medical instruments. The glaucoma drainage device comprises a drainage body and a flow guide body, the drainage body comprises a hollow drainage main body and a main drainage tube, and the drainage main body is communicated with the main drainage tube; the flow guide body comprises a flow guide base and a flow guide pipe arranged on the flow guide base, and the flow guide pipe is communicated with the drainage body. By the adoption of the drainage device, aqueous humor is drained through the drainage body, the aqueous humor flows in through the main through hole and the auxiliary through hole, the effects of filtering and shunting the aqueous humor are achieved, and the main through hole and the auxiliary through hole are prevented from being blocked; the sclera bed and the sclera flap are separated through the flow guide pipe, continuous existence of a functional liquid cavity gap is maintained, a permanent aqueous humor drainage channel is built, and adhesion between sclera is effectively prevented. The problem that the operation effect is affected due to cicatrization of a filtering channel after the glaucoma operation at present is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a glaucoma drainage device. Background technique [0002] Glaucoma is an eye disease caused by intermittent or persistent increase in intraocular pressure, mainly due to poor drainage of intraocular aqueous humor, which increases intraocular pressure, damages various parts of the eyeball and visual function, and eventually leads to optic atrophy And blind. Therefore, draining the aqueous humor and creating a permanent drainage channel for the eye has become a critical step in the surgery. At present, the most commonly used surgical method at home and abroad is glaucoma drainage device implantation. Glaucoma drainage device implantation is to implant an artificially designed drainage device into the anterior or posterior chamber, and through the diffusion device, the aqueous humor is drained to the subconjunctival sac or subfascial sac. [0003] Scar is a general term f...
