Description
Technical field
Present invention relates particularly to the field of medical instrument technology, and in particular to a kind of artificial lens.
Background technique
It is the crystal for removing eyes that treatment at present, which is referred to as a kind of known method of the eye disease of cataract, and uses artificial lens
Substitute as the crystal.When using such artificial lens, the crystalline substance for removing crystal nuclear and cortex need to be implanted into
In shape somatocyst bag.For the trouble eye supported without enough pouches, needs to adopt and be implanted into other methods, mainly there is ciliary body seam at present
The modes such as line is fixed, sclera interlayer is fixed, sclera hook is fixed.Wherein sclera hook fixing means is what the present inventor had applied
International monopoly.By the artificial lens loop of three-chip type, reflexed returns glass again outside adjacent two sclera miniature incisions pull-out sclera for we
Glass body cavity forms fish hook shape, while doing sqclerotal layer groove between two adjacent scleral incisions to bury crystal loop.The party
Method improves the stability and property placed in the middle of artificial lens, and surgical procedure is simple, is easily mastered, and reduces operating time.It is applying
During sclera links up with fixed implantation, it has been found that in place of existing three-chip type artificial lens comes with some shortcomings: first is that
Length is inadequate.It needs to pull out loop into enough length in art, if the long deficiency of loop can lead to loop and optical surface tie point receiving is larger
Strength, may cause falling off for loop, while the loop bending degree at hook is larger, so that sclera is withstood more force, for a long time
It may cause the fracture damage of sclera.Second is that in the patient of some irises relaxation, it is easy to appear iris incarcerations after crystal
Complication, patient have certain sense of discomfort.The artificial lens that this patent proposes can preferably match the new side of sclera hook implantation
Method avoids the occurrence of problems.The method of further perfect sclera hook implantation, further shortens operating time, consolidates art
Curative effect afterwards facilitates the further genralrlization of this method.
Summary of the invention

The technical solution that the present invention uses is: a kind of artificial lens, including optical section, and the optical section two sides are set
There is crystal loop structure, connection structure, the optical section and crystal loop are additionally provided between the optical section and crystal loop structure
It is connected between structure by connection structure, one end of the crystal loop structure is formed with the connecting pin of enclosed construction, described
The connecting pin of enclosed construction is installed in connection structure, and the connection structure extends to form raised knot to the side of optical section
The connecting pin of structure, the crystal loop structure is installed on bulge-structure, non-total between the connecting pin and optics facial planes
Face setting.
Non-co-planar setting between the bulge-structure and optics facial planes.
The connecting pin of the enclosed construction forms the enclosed construction of nearly triangle, and the bottom edge of the enclosed construction of triangle is embedding
In in bulge-structure.
The thickness of the connection structure is greater than the thickness of optical section.
The connection structure is arc-shaped structure, and the connection structure center symmetric setting is in optical section two sides.
Several graduated scales are provided on the other end opposite with the connecting pin of enclosed construction of the crystal loop structure
Note.
The end of the crystal loop structure (2) is barb-like or expands shape, prevents the postoperative abjection of crystal loop.
Flexi-ring is additionally provided on the end of the other end opposite with the connecting pin of enclosed construction of the crystal loop structure
Structure.
The concave structure for facilitating cutting is provided between the flexi-ring structure and crystal loop structure.
The centrosymmetric both sides of the edge of the optical section extend outward to form connection structure, the connection structure
Thickness is greater than the thickness of optical section.
The beneficial effects of the present invention are: the present invention provides a kind of artificial lens, by optical section and crystal loop structure
Between connection structure is set, between optical section and crystal loop structure by connection structure be connected, one end of crystal loop structure is formed
There is the connecting pin of enclosed construction, the connecting pin of the enclosed construction is installed on connection structure, reaches optical section and crystal loop knot
Connection structure is closer between structure, and will not be to the effect that optical section impacts, and between connecting pin and optics facial planes
It is non-co-planar to be arranged on the bulge-structure of connection structure, the phenomenon that can effectively avoid iris incarceration generation.
