Description

A kind of intraocular lens's fixed network

Technical field

This utility model relates to ophthalmic medical utensil field, a kind of intraocular lens's fixed network when aphakia cyst membrane eye intraocular lens that particularly a variety of causes causes implants.

Background technology

Clinically, the ophthalmic patient of the ill-mannered lens capsule that a variety of causes causes, need to implement implantation of artificial lens.In operation, the enforcement of crystalline lens fixed position and fixing means is most important on the recovery impact of Postoperative visual acuity.In prior art, two kinds of methods enforcement intraocular lenss of main employing fix, and the one, adopting fixedly intraocular lens of 2 suspentions, easily cause the problems such as intraocular lens's bias and rotation, and affect the effect that Postoperative visual acuity is recovered; The fixing mode of 4 of employing fixed networks that also have or multiple spot is intraocular lens fixedly, but it is lax easily to produce fixed network, and intraocular lens can not accurately be fixed, and the final effect that impact is performed the operation.

Utility model content

The drawback that this utility model exists fixedly time for crystalline lens in implantation of artificial lens in prior art, provide a kind of succinct, easy to operate intraocular lens's fixed network that designs, the defects such as the crystalline lens that occurs when avoiding intraocular lens to implant is eccentric, rotation or dislocation.

The purpose of this utility model is to realize like this, a kind of intraocular lens's fixed network, comprise the equilateral triangle net that the length of side that polypropylene for medical article prepared material is made is 10-12mm, three vertex positions of described equilateral triangle net are fixedly connected with respectively the static line that is useful on ligation.Adopt triangle fixed network of the present utility model for fixing manually crystalline, the posterior capsulotomy of simulation human eye self, implanting at latter 3 fixes, make the ophthalmic that is fixed on that fixed network can be stable, fixing with respect to 2 suspentions, there will not be the problems such as the eccentric and rotation of crystalline lens, with respect to 4 or multiple spot fixed network, fix, can not occur to cause that because wherein one or two fixing point is loose crystalline position is unstable.Intraocular lens's fixed network of the present utility model adopts polypropylene material in addition, has the good compatibility with eye inner tissue, and intraocular lens's taking-up in the time of can facilitating other operation to need can not occur to repel and degradation problem.

As improvement of the present utility model, the grid in described equilateral triangle net is triangular in shape.

As of the present utility model, further improve, described equilateral triangle net comprises the equilateral triangle screen frame of most peripheral, with the equilateral triangle grid one connecing in equilateral triangle screen frame, with the equilateral triangle grid two connecing in equilateral triangle grid one.Equilateral triangle fixed network structure of the present utility model, along outer circumferential center, it is close that mesh-density becomes gradually, is convenient to make ball to fill the center that triangle fixed network is firmly fixed at lenticular center.

As of the present utility model, further improve, the wire diameter of described netting twine is 0.1～0.2mm.

Accompanying drawing explanation

Fig. 1 is the structural representation of intraocular lens's fixed network of the present utility model.

Fig. 2 is intraocular lens's fixed network of the present utility model for fixing intraocular lens's schematic diagram.

Wherein, 1 network of triangle; 1a triangle screen frame; 1b equilateral triangle grid one; 1c equilateral triangle grid two; 2 static lines; 3 intraocular lenss; 4 ciliary ring; The main otch of 5 cornea; 6 cornea side otch; 7 conjunctival flaps.

The specific embodiment

Be illustrated in figure 1 intraocular lens's fixed network of the present utility model, comprise the equilateral triangle net 1 that the length of side that polypropylene for medical article prepared material is made is 10-12mm, three vertex positions of equilateral triangle net are fixedly connected with respectively the static line 2 that is useful on ligation; Grid in equilateral triangle net 1 is triangular in shape, this structure of tool is the equilateral triangle screen frame 1a that equilateral triangle net 1 comprises most peripheral, with equilateral triangle grid one 1b connecing in equilateral triangle screen frame 1a, with equilateral triangle grid two 1c that connect in equilateral triangle grid one 1b, wherein, the wire diameter of netting twine is 0.1～0.2mm.

While adopting artificial crystalline shape of the present utility model fixedly, respectively at the 12:00 point apart from patient's ciliary ring 4 periphery 1mm places, 4:00 point, 8:00 point position, make 3 little conjunctival flaps 7, and make respectively and take 2mm * 2mm, the thick triangle scleral flap of thick approximately 1/3 sclera that limbus of corneae is substrate; The main otch 5 of cornea of making 3.2 mm in 1～2mm place, inner side, 12:00 position of ciliary ring 4,6:00 position, below makes cornea side otch 6; With No. 5 syringe needles, after the limbus of corneae of 4:00 point position, thrust eyeball in 1.5mm place, first minute hand of use of first static line of intraocular lens's fixed network entering from the main otch 5 of 12:00 parallactic angle film drawn eyeball; With method, with second minute hand, second static line of fixed network drawn outside eyeball from 8:00 point position; From below, 6:00 parallactic angle film side otch is drawn the 3rd static line outside eye with the 3rd minute hand, then thrust eyeball with No. 5 syringe needles the 3rd pin drawn to eyeball from 12:00 position again at 1.5mm place after the limbus of corneae of 12:00 position.Strain respectively 3 static lines, intraocular lens's fixed network is positioned over to ciliary groove; 3 static lines 2 are fixed in ligation respectively; By injector, three-chip type foldable intraocular lens 3 is pushed to anterior chamber, then with intraocular lens's hook of transposing, intraocular lens 3 rotation is made it between iris and fixed network, and in horizontal position, continue follow-up operation process.

Adopt triangle fixed network of the present utility model for fixing manually crystalline, the posterior capsulotomy of simulation human eye self, implanting at latter 3 fixes, make the ophthalmic that is fixed on that fixed network can be stable, fixing with respect to 2 suspentions, there will not be the problems such as the eccentric and rotation of crystalline lens, with respect to 4 or multiple spot fixed network, fix, can not occur to cause that because wherein one or two fixing point is loose crystalline position is unstable.Intraocular lens's fixed network of the present utility model adopts polypropylene material in addition, has the good compatibility with eye inner tissue, and intraocular lens's taking-up in the time of can facilitating other operation to need can not occur to repel and degradation problem.
