Abstract
The utility model discloses a kind of artificial iris with pouch, including top layer iris, bottom iris and the retainer ring of more than two；The center of described top layer iris opens up an endoporus, and top layer iris is fixed together with bottom iris outer rim, forms a pouch, and junction opens up one for the lenticular opening of implantable artificial at the top of top layer iris and bottom iris；The retainer ring of described more than two is fixedly mounted on the back side of bottom iris.Because the utility model is installed with retainer ring when fixing artificial iris as suture at the back side of iris body, the retainer ring that suture may pass through iris body is fixed in scleral walls.In addition, it is material that the utility model uses acrylate, make the ultra-thin artificial iris tissue with pouch, the even more small otch of 2.8mm otch is only needed when intraocular is implanted into after folding, during secondary implantation intraocular lens, can be implanted directly into pouch, intraocular lens again by prolene suture without being fixed on eyeball scleral walls.
Description
Technical field
The utility model is related to medical instruments field, more particularly to a kind of artificial iris with pouch.
Background technology
Artificial iris are commonly applied in the full missing of aniridia or excalation trauma eyes, for the wound of eyeground better function
Eye, need to often combine implantable artificial crystal, there is the intraocular lens with Artificial iris diaphragm on the market at present, can reach simultaneously a phase
To the effect of artificial iris and intraocular lens, but implantation intraocular need to through larger corneal incision, to bringing Ocular hypotension in operation,
The risk of explosive Suprachorodal hemorrhage, at the same Post operation corneal incision residual astigmatism it is larger, cause cornea rebirth blood vessel compared with
It is many；Also there are intraocular lens and artificial iris gradation implantation situation, but secondary implantation is both needed to do scleral flap otch by ciliary groove
Suture is fixed, and increased bleeding, to stimulating again for ciliary body.
Utility model content
The purpose of this utility model is to provide a kind of people with pouch for being easy to fix and be easily implantable intraocular lens
Work iris.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of artificial iris with pouch, including top layer iris, bottom iris and more than two are consolidated
Determine ring；The center of described top layer iris opens up an endoporus, and top layer iris is fixed together with bottom iris outer rim, forms one
Individual pouch, junction opens up one for the lenticular opening of implantable artificial at the top of top layer iris and bottom iris；Described
The retainer ring of more than two is fixedly mounted on the back side of bottom iris.
Described retainer ring is four, and four retainer rings are two-by-two one group, are arranged in parallel up and down, and retainer ring is semicircle.
The described positive color of top layer iris is imitated by computer collection patient health iris color and texture
Form, external diameter 11-13mm, diameter of bore 3-5mm, thickness 0.2-0.4mm.
Described retainer ring is semicircle, its a diameter of 0.2mm.
After using such scheme, people is fixed as suture because the utility model is installed with the back side of iris body
Retainer ring during work iris, suture may pass through the retainer ring of iris body, be fixed on 1.5 millimeters after corneoscleral junction of scleral walls
On, reach fixed the purpose of this utility model.Additionally, it is material that the utility model uses acrylate, ultra-thin band pouch is made
Artificial iris tissue, after folding be implanted into intraocular when only need the even more small otch of 2.8mm otch, by consolidating after Artificial iris diaphragm
Determine ring combination prolene suture and be fixed on eyeball sclera flaggy, during secondary implantation intraocular lens, can be implanted directly into pouch, people
Work crystalline lens again by prolene suture without being fixed on eyeball scleral walls；Simultaneously because top layer iris color is adopted by computer
Collection, it can be ensured that its texture and color are consistent with the iris color Acacia crassicarpaA of another healthy eye of patient, it is ensured that postoperative patient
The natural beauty of eyes.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

Specific embodiment
As Figure 1-Figure 5, the utility model is a kind of artificial iris with pouch, including top layer iris 1, bottom iris
2 and four retainer rings 3.
The center of described top layer iris 1 opens up an endoporus 11, and top layer iris 1 is fixed on one with the outer rim of bottom iris 2
Rise, form a pouch, one is opened up for implantable artificial crystalline lens 4 in top layer iris 1 and the top junction of bottom iris 2
Opening 12.
Four described retainer rings 3 are two-by-two one group, are arranged in parallel up and down, are respectively and fixedly installed to the back of the body of bottom iris 2
Face, pin during artificial iris is fixed as suture.In the present embodiment, described retainer ring 3 is semicircle, and its is a diameter of
0.2mm。
Described top layer iris 1 is all made with bottom iris 2 of acrylate material, the positive face of top layer iris 1
Color and texture are copied and formed according to the strong eye iris color of computer collection and texture, the external diameter 11-13mm of top layer iris 1, endoporus
Diameter 3-5mm, thickness 0.2-0.4mm.
Surgical procedure of the present utility model：
As shown in fig. 6, during operation, iris body 1 is implanted into intraocular after folding by 2.8mm otch, reinflated.
As shown in Figure 7, Figure 8, suture 10 may pass through four retainer rings 3 of iris body 1, be fixed on 1.5 after corneoscleral junction
In the scleral walls 20 of millimeter, fixed purpose is reached.
As shown in figure 9, the opening 12 by intraocular lens between top layer iris 1 and bottom iris 2 is implanted into, without extra
It is fixed.
The above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalence changes made according to present utility model application the scope of the claims and description and modification, all should still belong to this reality
In the range of being covered with new patent.
