Abstract
The utility model relates to a three-line suspension artificial crystal which belongs to the man-made substitute class of the constituent part of the human eye. The artificial crystal is changed into the suspension line type form the supporting loop type. Three suspension lines are fixedly connected to the artificial crystal, and the ends of the suspension lines are respectively connected with a fine sewing needle. Because the three points form a plane, and thus the artificial crystal is stably fixed in the human eye. The utility model has the advantages of simple operation, great use reliability, safety, long service life, etc.
Description
The utility model relates to a kind of ingredient of eyes---lenticular graft belongs to the artificial category that substitutes of human eye ingredient.
Now both at home and abroad human lens succedaneum---artificial intraocular lenses's crystal seed is more, particularly China is very fast in the development of artificial intraocular lenses field recently, but belonging to basically, they support loop formula artificial intraocular lenses, promptly form by artificial intraocular lenses 1 and two support loops 2, see Fig. 1, two are supported loop 2 and are connected in symmetrically on the artificial intraocular lenses 1.This artificial intraocular lenses utilizes this two to have only the loop of favorable elasticity to be supported on ophthalmic, but this support loop formula artificial intraocular lenses utilizes the intact back cyst membrane of postoperative to implant after only being applicable to an extracapsular cataract extraction.If patient lacks back cyst membrane (as traumatic cataract and the lenticular patient of freezing excision), just need be sewn on two loops of this kind artificial intraocular lenses in the ciliary groove of eyeball, the step of this operation is just very complicated, and owing to be two point locations, therefore easily produce artificial intraocular lenses's inclination and dislocation, thus the recovery of influence operation back vision.China has the ophthalmologist more than 85% implementing intracapsular cataract extraction approximately at present, because of extraction back cyst membrane existence without male offspring in the capsule, so can not implant above-mentioned artificial intraocular lenses, has influenced the popularization of China artificial intraocular lenses implant surgery.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and a kind of suspension artificial intraocular lenses who uses applicable to no cyst membrane patient who provides.
This utility model is to change the artificial intraocular lenses into suspention line formula by supporting the loop formula, promptly on the artificial intraocular lenses, be fixedly connected with three suspention lines, owing to can determine a plane at 3, therefore after the artificial intraocular lenses implants ophthalmic, three suspention lines pass ophthalmic sclera and knotting respectively, thereby the artificial intraocular lenses can stably be fixed in the eyes.
This utility model also can respectively be fixed with the finedraw pin in the end of three suspention lines, can easily the artificial intraocular lenses be fixed in the eyes like this.
Description of drawings is as follows:
Fig. 1 is the structural representation that supports loop formula artificial intraocular lenses.
Fig. 2 is the sketch map of structure of the present utility model.
To be described in detail this utility model by accompanying drawing below: accompanying drawing 2, be evenly equipped with three thinner suspention lines made from polypropylene or titanium fluorine human relations (Teflon) material 4 by hexagonal angle on artificial intraocular lenses 3 the periphery, and be connected with finedraw pin 5 separately in the end of suspention line 4.Owing to can determine a plane at 3, therefore artificial intraocular lenses 3 is provided with and can stably fixes after three suspention lines 4 can make in artificial intraocular lenses's 3 implanted human eyes, can not occur tilting and dislocation, more because three suspention lines 4 are to be distributed on artificial intraocular lenses's the periphery by hexagonal angle, thus stressed evenly.Directly being connected with finedraw pin 5 in the end of three suspention lines can make operation convenient, reliable.During operation, finedraw pin 5 band wire directly pass the sclera of human body ophthalmic, and knotting is fixing outside sclera.
The utility model compared with prior art, have following several characteristics: (1), can be under than the simple and crude equipment condition, even in the situation that lacks surgical operation microscope, implant, particularly be fit to the absolutely big number eye doctor of China and implant this kind artificial lens on the basis of existing freezing cataract extraction technology. (2), applied widely, complete or take off in the mistake situation and all can implant at vitreum. (3), the operation good reliability, send out barrier after postoperative never takes place, do not need again to perform the operation. (4), fixation, long service life can not produce that artificial lens tilts and dislocation, is convenient to from now on inspection and the processing of intraocular complication simultaneously yet.
Claims (2)
1, a kind ofly is used for intraocular three-way suspension artificial intraocular lenses, it is characterized in that being fixedly connected with on the artificial intraocular lenses (3) three suspention lines (4).
2, three-way suspension artificial intraocular lenses as claimed in claim 1 is characterized in that the end of described suspention line (4) respectively is connected with finedraw pin (5).
