Embodiment Construction

[0027] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. In the surgical treatment of glaucoma, it is necessary to make a scleral flap, and then make an incision at the corneoscleral limbus under the scleral flap, so that the water in the eyeball will flow out from the incision to reduce intraocular pressure. At present, most of the treatment methods are to install a drainage device in the eye. Doing so may resolve the temporary IOP rise, but the adhesion between the scleral flap and scleral bed remains unresolved.

[0028] see Figure 1-4 , the present invention proposes a glaucoma drainage device, which is implanted between the scleral flap and the scleral bed, which includes at least two support ...

Abstract

The invention discloses a glaucoma drainage device, and relates to the technical field of glaucoma surgical treatment equipment. The glaucoma drainage device comprises at least two supporting bodies, wherein one supporting body located at one end of the glaucoma drainage device is provided with a suture hole used for being sewn together with a sclera bed and a forward extending body used for extending to the glaucoma operation corner and the sclera margin incision edge, and the upper portion and the lower portion of each supporting body are integrally connected with a V-shaped elastic fiber body. By means of the glaucoma drainage device, adhesion of sclera flaps after the operation is prevented, the drainage effect of a filtering operation is obviously improved and enhanced, and the success rate of the operation is increased.

Description

technical field [0001] The invention relates to the technical field of glaucoma surgical treatment equipment, in particular to a glaucoma drainage device. Background technique [0002] Glaucoma is a common and difficult eye disease with rapid onset, great harm and can lead to blindness at any time. The characteristic is that the level of intraocular pressure intermittently or persistently increases beyond the tolerance of the eyeball, causing damage to various parts of the eyeball tissue and visual function. It can compress the optic nerve, causing optic atrophy, narrowing of the field of vision, and loss of vision. In the long run it will lead to blindness. [0003] Surgery is the mainstay of treatment for glaucoma. Excessive intraocular pressure is an important cause of glaucoma. Therefore, drawing out the aqueous humor and making a permanent drainage channel for the eye, that is, forming a filtering bleb, has become a key step in the operation. [0004] However, after...
