Abstract
The utility model belongs to the technical field of medical instruments and devices and particularly relates to a multifunctional glaucoma aqueous humor drainage device. The multifunctional glaucoma aqueous humor drainage device comprises a drainage tray, wherein the drainage tray is connected with a drainage tube, and a plurality of liquid seepage holes are formed in the drainage tray. The multifunctional glaucoma aqueous humor drainage device is characterized in that a liquid inlet tube is connected to the top end of the drainage tube, a falling prevention clip and a leakage proof clip which are mounted on the drainage tube are arranged between the liquid inlet tube and the drainage tube, the drainage tube is filled with sustained-release grains, fixing feet are connected to the tail end of the drainage tray, and a pressure ridge which is mounted on the drainage tray is arranged at the joint between the drainage tube and the drainage tray. The multifunctional glaucoma aqueous humor drainage device has the beneficial effects that the postoperative intraocular pressure lowering effect is obvious, complications, such as shallow anterior chamber hypotony, are reduced, the leakage of eyeball conjunctivae and eyeball fasciae cannot occur, the structure is simple, and the operative operation is convenient, so that the multifunctional glaucoma aqueous humor drainage device is applicable to the operative treatment of glaucoma patients, particularly refractory glaucoma patients.
Description
(1) technical field
This utility model belongs to medical device technical field, particularly a kind of multi-functional aqueous humor drainage device for glaucoma.
(2) background technology
As everyone knows, there is the high intraocular pressure of pathologic or be called glaucoma depending on the bad optic nerve lesion causing of nipple blood perfusion and visual disorder person.The aqueous humor flowing out through Valve implanation can lead in bulbar conjunctiva gap, rear portion, vein or eye socket tissue and be absorbed, and reduces and maintains intraocular pressure at certain level, the object of maintenance visual function to reach.At present, known aqueous humor drainage device for glaucoma is to be made into integration by drainage tube, drainage disc, liquid-leadage hole, during Operation, need to cut conjunctive bulbi and fascia, drainage disc is fixed on eyeball sclera to the postoperative conjunctive bulbi otch seepage that is prone to, because there is no leakproof card, postoperatively be prone to corneosclera otch seepage, and be prone to shallow of anterior chamber, cause operation technique difficulty.
(3) summary of the invention
This utility model is in order to make up the deficiencies in the prior art, a kind of simple in structure, easy to operate, available buffer drain is provided, avoids the complication such as postoperative ocular hypotension, has been difficult for occurring the multi-functional aqueous humor drainage device for glaucoma of conjunctive bulbi otch and corneosclera otch seepage.
This utility model is achieved by the following technical solution:
A kind of multi-functional aqueous humor drainage device for glaucoma, comprise drainage disc, drainage disc is connected with drainage tube, on drainage disc, offer some liquid-leadage holes, it is characterized in that: described drainage tube top is connected with feed tube, between feed tube and drainage tube, be provided with the Anti-release clamp and the leakproof card that are installed on drainage tube, in drainage tube, be filled with slow-releasing granules, drainage disc end is connected with fixing feet, and drainage tube and drainage disc junction are provided with the pressure ridge being installed on drainage disc.
On described feed tube, evenly offer some inlet openings.
Between described drainage disc and drainage tube, be provided with the fixing head that is installed on drainage disc front portion, fixing head is provided with stitching fixing hole.
The beneficial effects of the utility model are: postoperative intraocular pressure lowering successful, reduced the complication such as shallow of anterior chamber ocular hypotension, conjunctive bulbi and fascia bulbi seepage can not occur, simple in structure, operation technique convenience, be applicable to glaucoma patient, especially the operative treatment of intractable glaucoma patient.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 drainage disc, 2 drainage tubes, 3 liquid-leadage holes, 4 feed tubes, 5 Anti-release clamps, 6 leakproof cards, 7 slow-releasing granules, 8 fixing feet, 9 pressure ridges, 10 inlet openings, 11 fixing heads, 12 sew up fixing hole.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises drainage disc 1, drainage disc 1 is connected with drainage tube 2, on drainage disc 1, offer some liquid-leadage holes 3, drainage tube 2 tops are connected with feed tube 4, between feed tube 4 and drainage tube 2, be provided with the Anti-release clamp 5 and the leakproof card 6 that are installed on drainage tube 2, in drainage tube 2, be filled with slow-releasing granules 7, drainage disc 1 end is connected with fixing feet 8, and drainage tube 2 is provided with drainage disc 1 junction the pressure ridge 9 being installed on drainage disc 1.On feed tube 4, evenly offer some inlet openings 10.Between drainage disc 1 and drainage tube 2, be provided with the fixing head 11 that is installed on drainage disc 1 front portion, fixing head 11 is provided with sews up fixing hole 12.
Adopt a kind of multi-functional aqueous humor drainage device for glaucoma of the present utility model, during operation, fixing feet 8 and drainage disc 1 are implanted to fascia bulbi chamber by corneal incision, by corneosclera otch, implant drainage tube 2, make drainage tube 2 internal orifices be positioned at iris front portion, sew up corneal incision and reach watertight state.Feed tube 4 has elasticity, and the inlet opening 10 of offering on it has reduced the incidence rate that drainage tube 2 blocks to a great extent.Leakproof card 6 can prevent in art, postoperative corneosclera otch seepage, and Anti-release clamp 5 can prevent that whole device is to retrolisthesis.The effect of liquid-leadage hole 3 is be conducive to aqueous humor drainage to fascia bulbi and be absorbed, and slow-releasing granules 7 can prevent in art, postoperative generation shallow of anterior chamber and prevent out blood stasis drainage tube 2.Pressure ridge 9 is divided into two parts by drainage disc 1, and its effect is that early postoperative period aqueous humor has been flowed out to certain obstruction and cushioning effect, can effectively prevent and reduce the generation of the complication such as postoperative early stage shallow of anterior chamber and ocular hypotension.Fixing head 11 arranges two and sews up fixing hole 12, suture and embedding toe-in while being convenient to perform the operation.
