Glaucoma drainage device

Abstract

The invention provides a glaucoma drainage device which is used for draining aqueous humor to tissues or lymphatic vessels. The device comprises: a drainage disc which is provided with an upper surface and a lower surface, wherein the upper surface is provided with a plurality of drainage grooves which are uniformly dispersed in a spoke shape, and a drainage tube groove is arranged between the upper surface and the lower surface; a drainage tube which penetrates through the drainage tube groove and is used for inflow of aqueous humor; and a liquid storage chamber which is vertically arranged at the central position of the drainage disc, is connected to the drainage tube which penetrates through the drainage tube groove, is further communicated with the multiple drainage grooves and is usedfor containing the aqueous humor guided to the liquid storage chamber through the drainage tube groove by means of the drainage tube, wherein the aqueous humor in the liquid storage chamber flows into the multiple drainage grooves after overflowing, and a covering layer is arranged above the liquid storage cavity and used for covering the liquid storage cavity and the communication positions of the drainage grooves and the liquid storage cavity. The problems that drainage devices are uneven in outflow and prone to being blocked are solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a glaucoma drainage device. Background technique [0002] Currently, glaucoma is the second leading cause of irreversible blindness worldwide. Pathologically elevated intraocular pressure is a major risk factor for irreversible damage to the optic nerve caused by glaucoma. At present, the treatment of glaucoma mainly includes drug therapy and drainage implantation. At present, the main treatment option for refractory glaucoma is implantation of aqueous humor drainage. [0003] However, the outlet of the existing aqueous humor drainage is often wrapped by the surrounding scar tissue, which makes the drainage of the aqueous humor difficult and eventually loses its effectiveness. In addition, in view of the prior art, the uniformity of the outflow of aqueous humor has not been fully considered, which may affect the excessive stimulation of the drainage to the ...

Problems solved by technology

[0003] However, the outlet of the existing aqueous humor drainage is often wrapped by the surrounding scar tissue, which makes the drainage of the aqueous humor difficult and eventually loses its effectiveness

In addition, in view of the prior art, the uniformity of the outflow of aqueous humor has not been fully considered, which may affect the excessive stimulation of the drainage to the cells. For example, the existing drainage devices are all from the side of the inlet. enter, and the outlet is set on the other side, which will cause the outflow of aqueous humor to not achieve reliable uniformity
