Description
Technical field
The utility model is related to technical field of medical equipment, and in particular to a kind of aqueous humor drainage device for glaucoma.
Background technology
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 makes intraocular pressure increase since the exclusion of intraocular aqueous humor has some setbacks, and eventually leads to optic atrophy and have a sleepless night.
Currently, for glaucoma treatment, both at home and abroad the most commonly used is the merging of the Glaucoma Drainage valve of preceding room pipe built-in type,
Presently known aqueous humor drainage device for glaucoma is integrated drainage tube, drainage disc, sepage mouth, when operation, needs to cut eyeball
Drainage disc is fixed on eyeball sclera by conjunctiva and fascia, postoperative the complication such as conjunctive bulbi notch leakage easily occur, and is performed the operation
When difficulty complicated for operation, safety is high.
Utility model content
The purpose of the utility model is to overcome the above-mentioned problems in the prior art, a kind of Aqueous Humor of Glaucomas is provided and is drawn
Device is flowed, simple in structure, surgical procedure convenience, postoperative complications reduce, are safe and practical.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：
A kind of aqueous humor drainage device for glaucoma, including infusing device and drainage tube, the infusing device include injector and
Pipe is injected, it is sharp keen to inject tip end, and the drainage tube is hollow drainage tube, and there is drainage valve port in drainage tube one end, close to drain valve
There are sepage mouth, the other end of drainage tube to be provided with multiple external draining holes on the drainage tube of mouth.
Preferably, described inject pipe, drainage tube is all made of medical silica-gel or hydrophilic acrylic acid ester.
Preferably, a diameter of 2-3mm of the drainage tube.
Preferably, the drainage valve port diameter is slightly larger than drainage tube.
The utility model has the beneficial effects that：
1, the utility model main member is infusing device and drainage tube, is medical silica-gel or hydrophilic acrylic acid ester,
Simple in structure, easy to operate, cost is cheap.
2, the utility model is directly pierced through by the sharp keen pipe of injecting in tip below cornea in Aqueous Humor of Glaucomas drainage
Room angle, room angle is pierced through into one end with drainage valve port on drainage tube and be implanted into intraocular, by sepage mouth on drainage tube and outer
Intraocular aqueous humor is drawn outside eye and is seeped under conjunctiva by portion's draining hole, achievees the purpose that Aqueous Humor of Glaucomas drains.
3, well known integral type aqueous humor drainage device for glaucoma is compared, the utility model need not cut eye at the time of surgery,
Bulbar conjunctiva and fascia need not say that drainage disc is fixed on eyeball sclera, and postoperative complication reduces, safe and practical.
Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
