Technical field
The present invention relates to a kind of glaucoma drainage devices, belong to the field of medical instrument technology.
Background technique
Glaucoma is to rank the blinding eye disease of irreversibility and main one of the blinding eye disease in China in the whole world second.
Glaucoma mainly increases intraocular pressure since the discharge of intraocular aqueous humor is unsmooth, and eventually leads to optic atrophy and blind, right
In Refractory Glaucoma, most common art formula is Glaucoma Drainage valve implantation both at home and abroad at present.
Existing Glaucoma Drainage valve is mainly by a flexible silicone tube (i.e. drainage tube) and one and silicone tube one end
The drainage disc composition that (collar extension) is fixedly connected.When implantation, first drainage disc is planted under conjunctiva outside eye, then by the other end of silicone tube
It inserts in intraocularly, by tissue resorption outside eye after flowing out intraocular aqueous humor from collar extension end by silicone tube, reaching reduces intraocular pressure mesh
's.
But after using existing Glaucoma Drainage valve implantation drainage device, collar extension usually can be by ever-increasing scar around
Trace tissue occlusion, and these tissue scarring (tissue adhesions) cover drainage tube opening, lead to not drain, to make room
Water discharge is unsmooth, and intraocular pressure gradually rises, final operative failure, therefore is badly in need of a kind of flow diverter for treating glaucoma, solves green light
The technical issues of eye therapeutic process drainage failure.
Summary of the invention
The purpose of the present invention is to solve the above problems, and then provide a kind of glaucoma drainage device.

A kind of glaucoma drainage device includes drainage tube, screening glass, connector sleeve and diversion pipe, and the drainage tube is hollow pipe
One end of body, drainage tube drains intraocular aqueous humor in tip-like, and the other end of drainage tube connects screening glass, and the screening glass is arc
Shape is bent dome-shaped, is machined with drainage trough inside screening glass, one end of drainage trough is connected to drainage tube, and the other end of drainage trough is set
It sets at the top of screening glass, the diversion pipe is connected to by connector sleeve with the foundation of the other end of drainage trough；
The diversion pipe includes diversion tube and the water conservancy diversion sheet body being wholely set with diversion tube upper end, and water conservancy diversion sheet body is in
" mushroom " shape, the center of water conservancy diversion sheet body are machined with flow-guiding mouth, and flow-guiding mouth is connected to diversion tube, the diversion tube with
Flow-guiding mouth junction is provided with inlet non return check valve.
Preferred: the connector sleeve includes circular ring shape connector and the skirt of circular ring shape connector upper end is arranged in encloses portion,
The lower inner side wall of the circular ring shape connector is equipped with inner chamfer portion.
It is preferred: the upper end of the diversion tube with water conservancy diversion sheet body junction be machined with annular groove, described is unidirectional
Non-return valve includes check valve hinged seat and individual event valve cover, and the individual event valve cover and check valve hinged seat are articulated and connected, single
The installation of item valve cover is in a ring groove.
Preferred: the flow-guiding mouth is regular shape.
Preferred: the flow-guiding mouth is inverted trapezoidal, rectangular or arc-shaped.
The invention has the following advantages:
1, the present invention can significantly improve the success rate of Glaucoma Drainage valve implantation, reduce the generation of postoperative complications；
2, the present invention is further added by a diversion pipe in drainage main body, allows diversion pipe to extend to outside conjunctive bulbi, and stretch
The open end of the pipe outside conjunctiva becomes larger out, and drainage main body can be prevented by autologous tissue's scarring, when drainage tube blocks,
It can be realized by the way that the diversion pipe held on the protection sheet is arranged from outside dredging flow diverter, save the trouble from inside dredging.
3, the present invention can thoroughly solve Glaucoma Drainage valve and wrap up the problems such as blocking by cicatricial tissue, hence it is evident that improve glaucoma
The success rate of drain valve implantation reduces the generation of postoperative complications.
