Abstract
The utility model relates to an anti-glaucoma drainage device which is used for draining aqueous humor in sclera tissue which is implanted in eyes to reduce intraocular pressure of the glaucoma and prevent the sclera tissue at an operative incision point from regenerating and scar from forming. The utility model is characterized in that the drainage device is composed of a main body part, a front wing and a back wing, the main body part is a regular hexahedron, and the front wing and the back wing are connected with both sides of the main body part; drainage holes which are communicated are arranged on other four lateral surfaces of the main body part.
Description
This utility model relates to a kind of drainage system of implanting eyeball, specifically, aqueous humor can be drawn when this drainage system is implanted to ad-hoc location in the eye sclera tissue, reduces improper intraocular pressure, eliminates and prevent the consequence that glaucoma causes effectively.
Glaucoma is one of major reason of blinding, and treating one of glaucomatous means is to adopt operative treatment, implements the trabecular resection operation at present mostly.Though this operation success rate height tends to occur the situation of the formation of scleral tissue's regeneration of incision or sclera cicatrix after the operation, these two kinds of situations can cause the closure of conduction hole respectively and filter the road blocks again, and causes operation to prove an abortion.
The purpose of this utility model is to provide a kind of and can for good and all implants in the eyeball, effectively prevents the regeneration of postoperative wound place scleral tissue and the formation of cicatrix, and aqueous humor is normally flowed out from the anterior chamber basically, prevents the anti-blue or green light drainage system of the improper rising of intraocular pressure.
This utility model is realized by following technical scheme:
This utility model is made up of main part 1, front wing 3 and rear wing 4, and main part 1 is a regular hexahedron, and front wing 3 and rear wing 4 are connected in the both sides of main part 1, has the osculum 5 and 6 that communicates on other four sides of main part 1.This utility model is made by the material that adapts with the ocular tissue organism, implants in the eye sclera tissue with suitable.Arc surface is made in the side that main part 1 links to each other with front wing 3, on rear wing 4, be provided with a suture hole 2.
When glaucoma patient is implemented the trabecular resection operation, behind the excision girder, this drainage system is implanted, made in the breach after main part 1 embeds excision, can prevent the regeneration of incision scleral tissue and the formation of sclera cicatrix.And aqueous humor can be discharged by the osculum 5 on the main part 1 and 6, and improper intraocular pressure is reduced.
This utility model is simple in structure, implantation is convenient, can prevent the regeneration of scleral tissue and the formation of cicatrix effectively, improves the success rate of operation.
Description of drawings:
Fig. 1 is the front view of this utility model one embodiment;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
Below in conjunction with embodiment this utility model is further specified.
This utility model adopts the material that adapts with this organism of ocular tissue to make, and implants in the eye sclera tissue, as the PMMA(polymethyl methacrylate with suitable), hydrogel, glass etc.The side 1 that main part 1 is linked to each other with front wing 3 ' make the face of cylinder, the radius on this face of cylinder is 5.75mm, and is promptly roughly the same with the radius of normal person's limbus of corneae.For avoiding because drainage system transition drain, and cause eyeball to wither, the passage section of osculum 6 should be less than 3mm
2
When glaucoma patient is implemented the trabecular resection operation, behind the excision girder, this device main body part 1 is embedded in the breach after cut of limbus of corneae under the scleral flap, rear wing 4 is sewn on the sclera by suture hole 2 with 10/0 nylon suture, and front wing 3 is placed under the lobe in the limbus of corneae, then scleral flap is stitched back original position and make conjunctival flap and sew up.At this moment osculum 6 communicates with camera oculi anterior, and osculum 5 is managed on behalf of another with the Su Lin of angle of anterior chamber and communicated, and the aqueous humor in the camera oculi anterior just can successfully be discharged by osculum 6 and 5, and improper intraocular pressure is reduced.
Claims (3)
1, glaucoma drainage system, it is characterized in that: form by main part (1) and front wing (3) and rear wing (4), main part (1) is a regular hexahedron, front wing (3) and rear wing (4) are connected in the both sides of main part (1), have osculum (5) and (6) that communicate on other four sides of main part (1).
2, according to the described drainage system of claim 1, it is characterized in that: this device is made by the material that adapts with the ocular tissue organism; The suitable implantation in the eye sclera tissue.
3, according to the described drainage system of claim 1, it is characterized in that: the side (1 ') that main part (1) links to each other with front wing (3) is the face of cylinder, is provided with a suture hole (2) on rear wing (4).
