Abstract
This utility model relates to a kind of artificial iris, comprising external diameter is 11-13mm, internal diameter is the Silica hydrogel thin film of 5-6mm, the thickness of described Silica hydrogel thin film is 0.4mm, the outer rim ligation of described Silica hydrogel thin film has three anchor sutures of distribution triangular in shape, is provided with the circular hole that an internal diameter is 2-3mm near the outer rim of the described Silica hydrogel thin film wherein between two anchor sutures.Artificial iris design of the present utility model is succinct, easy to operate; The material of artificial iris is Silica hydrogel, has the good compatibility, can not repel and degrade with eye inner tissue; Static line is polypropylene, can not degrade, and can be permanently fixed; As because of other needs of performing the operation, the artificial iris of implantation can be taken out easily; The small sircle hole arranged near artificial iris outer rim, is convenient to the anterior chamber of aqueous humor and the circulation of back room in eyes filled with silicone oil, avoids intraocular pressure to raise; Hollow circular ring structure, so that postoperative examination of ocular fundus and implantable artificial crystalline lens grip.
Description
Technical field
This utility model relates to ophthalmic medical fixture fields, a kind of especially artificial iris.
Background technology
On clinical ophthalmology, the iris that a variety of causes causes comes off the damage maybe cannot repaired, and needs to carry out artificial iris implantation.In operation, conventional manual's iris material of employing and the compatibility of human eye bad, the sufferer ratio that rejection and degraded occur is higher.And after artificial iris is implanted, when injecting silicone oil to ophthalmic, before and after ophthalmic, room is obstructed and cause intraocular pressure to raise, thus the impact effect of performing the operation and post-operative recovery.
Utility model content
The present invention is directed to the problems referred to above that prior art exists, provide a kind of structure simple, implant convenient, good with human eye compatibility artificial iris.
The purpose of this utility model realizes like this, a kind of artificial iris, comprising external diameter is 11-13mm, internal diameter is the Silica hydrogel thin film of 5-6mm, the thickness of described Silica hydrogel thin film is 0.4mm, the outer rim ligation of described Silica hydrogel thin film has three anchor sutures of distribution triangular in shape, is provided with the circular hole that an internal diameter is 2-3mm near the outer rim of the described Silica hydrogel thin film wherein between two anchor sutures.
Fixing for ease of iris, described anchor suture is arranged at 12 positions of Silica hydrogel thin film outer rim respectively, 4 positions and 8 points.
As preferred version of the present utility model, described circular hole is arranged near the outer rim of Silica hydrogel thin film 6 positions.
As preferred version of the present utility model, described anchor suture is polypropylene material.
Therefore, artificial iris of the present utility model is adopted to have following beneficial effect:
1) design is comparatively succinct, easy to operate;
2) material of artificial iris is Silica hydrogel, has the good compatibility with eye inner tissue, can not repel and degrade;
3) static line is polypropylene, can not degrade, and can be permanently fixed;
4) as because of other needs of performing the operation, the artificial iris of implantation can be taken out easily;
5) this fixed network has 3 fixing points, makes artificial iris stably can be fixed on ophthalmic;
6) small sircle hole arranged near artificial iris outer rim, is convenient to the anterior chamber of aqueous humor and the circulation of back room in eyes filled with silicone oil, avoids intraocular pressure to raise;
7) central authorities of artificial iris are provided with annular distance, so that postoperative examination of ocular fundus and implantable artificial crystalline lens grip;
8) the photophobia phenomenon of aniridia patient is eliminated;
9) directly contact with cornea after avoiding aniridia patient Silicone oil injection and produce corneal toxic action.
Accompanying drawing explanation
Fig. 1 is the structural representation of artificial iris of the present utility model.
Detailed description of the invention
Be illustrated in figure 1 artificial iris of the present utility model, a kind of artificial iris, comprising external diameter is 11-13mm, internal diameter is the Silica hydrogel thin film 2 of 5-6mm, the thickness of Silica hydrogel thin film 2 is 0.4mm, the outer rim ligation of Silica hydrogel thin film 2 has three anchor sutures 1 of distribution triangular in shape, is provided with the circular hole 3 that an internal diameter is 2-3mm near the outer rim of the Silica hydrogel thin film 2 wherein between two anchor sutures.Wherein, anchor suture 1 is arranged at 12 positions of Silica hydrogel thin film 2 outer rim respectively, 4 positions and 8 points; Circular hole 3 is arranged near the outer rim of Silica hydrogel thin film 6 positions, and anchor suture 1 is polypropylene material.
The concrete operation method of artificial iris implant surgery of the present utility model is: make 3 little conjunctival flaps respectively at 12:00 point, 4:00 point, 8:00 point position, and to make respectively with limbus of corneae be the 2mm × 2mm of substrate, triangle scleral flap that thick about 1/3 sclera is thick.Make the main otch of 3.2 mm cornea in cornea 12:00 position, 6:00 position, below makes cornea side otch.Artificial cornea is implanted from the main otch of 12:00 parallactic angle film, after the limbus of corneae of 4:00 point position, 1.5mm place thrusts eyeball with No. 5 syringe needles, the minute hand of first anchor suture of the artificial iris entered from the main otch of 12:00 parallactic angle film is drawn outside eyeball; With method, the minute hand of the second artificial iris anchor suture is drawn outside eyeball from 8:00 point position.Autonomous for artificial iris otch is pushed ophthalmic.From 6:00 parallactic angle film side, below otch, the 3rd minute hand is drawn outside eye, then No. 5 syringe needles in 1.5mm place thrust eyeball by the 3rd pin again from 12:00 position extraction eyeball after the limbus of corneae of 12:00 position.Strain 3 static lines respectively, artificial iris is positioned over ciliary groove; 3 anchor sutures are fixed in ligation respectively, complete the implant surgery of artificial iris.
Claims (4)
