Abstract

The present invention provides a drainage device for a glaucoma valve filtration bleb site. The drainage device is composed of a drainage tube and a pushing assembly, and the pushing assembly is composed of a pushing rod and a puncture needle. The pushing rod is arranged on the front inner side of the drainage tube, and a puncture needle is arranged on the front end of the pushing rod. The anterior end of the drainage tube is an inclined plane for oblique gradual transition to engage with the puncture needle, and the posterior part of the drainage tube is placed in the conjunctival sac or fascial sac. A barb inverse locking structure is arranged on the outer side of the proximal tube wall of the front part of the drainage tube. The device has the advantages that the operation of implantingthe glaucoma valve wrapping bubble with the drainage device is simple, the glaucoma valve wrapping bubble need not be opened, the damage to the eye tissue is small, the wrapping caused by the fibrosis is effective, the drainage aqueous humor has the function of lubricating the eye surface, and the eye surface treatment is effective for the patients with severe dry eye.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a drainage device for the filter bubble part of glaucoma valve. Background technique [0002] Glaucoma, an eye disease that affects the retina and optic nerve, is one of the leading causes of blindness worldwide. Glaucoma results when pressure in the eye increases to a higher-than-normal pressure over a long period of time. The main reasons for the failure of refractory glaucoma treatment are tissue fibrosis and the formation of epilepsy scars in the surgical area, which hinder the drainage and diffusion of aqueous humor. At present, ophthalmologists often use glaucoma drainage devices to control the intraocular pressure of patients with refractory glaucoma, especially in the treatment of complex glaucoma. At present, there are many kinds of glaucoma drainage valves. An artificial pathway for aqueous drainage and diffusion that drains aqueous humor into the conjunctival or fas...
