Abstract
The invention aims at disclosing an artificial iris with location holes. The artificial iris with location holes is characterized in that the tail end of each loop of the artificial iris is provided with a location hole which is convenient for using a location hook to stretch the loop out from an incision of a sclera. Compared with the prior art, the location holes are processed at the loops of the artificial iris and the location holes are printed or marked with different color, so that the location hooks are easily used to hook the location holes of the artificial iris and stretch the loops of the artificial iris out from the incision of the sclera; and a suture is used to penetrate through each location hole, so that each loop is stitched in the wall of the sclera conveniently to fix the artificial iris and achieve the aim of the artificial iris with location holes.
Description
Technical field
The present invention relates to field of medical device, more particularly to a kind of artificial iris with location hole.
Background technology
Iris belongs to eyeball middle level, in front of ciliary body, there is the size for automatically adjusting pupil, plays a part of to adjust how many into intraocular light and limits aberration, changes the depth of field.Used as a kind of biologic soft tissue, iris has the viscous-elastic behaviour such as delayed, lax, creep, strain rate dependency.
The important mechanical characteristic of iris makes it when eye traumas or eye congenital anomaly cause aniridia or iridocoloboma, the dysfunction of eyeball, the such as increase of spherical aberration, astigmatism, low visual acuity after diplopia, dazzle, photophobia and wound, and visual acuity reduction etc. often occurs.
Because the iris of atrophy can not be allowed to regenerate by means such as medicines at present, the means of operation can only be adopted to be repaired.Conventional modus operandi has iris suture to be implanted into artificial iris.Iris suture is the elasticity of the normal iris tissue using patient's remaining, and iris tissue stretching is stitched together, and plays a part of certain control light and limits aberration.
At present, the major way of intraocular fixation artificial implantation has suture fixed form and button loop supporting way.
Suture fixed form is to pass suture through fixed by bundle of lines artificial implantation after tissue, intraocular limited space, and suture overlap joint within the eye is extremely difficult, and operation technique difficulty is big, and surgical effect is limited.
Button loop supporting way is in the space of a limitation closing, the end of closing space is withstood using button loop, play a supporting role, this modus operandi is simple, it is easy to operate, it is fixed in the pouch of such as intraocular lens, but being limited in that for the method can only be performed the operation in the space of closing, be not particularly suited for the fixation of the artificial iris in anterior chamber angle or ciliary groove etc..
Existing artificial iris operation is generally fixed on the iris of remaining or iris root in the way of suture, or in ciliary groove, which needs the suture and knotting operation that complexity is carried out in narrow within the eye, closing space, and operating difficulty is big, limits the development of operation.Making the patient of numerous iridocolobomas cannot effectively treat.
Band button loop artificial iris are flexible material, and the button loop of artificial iris needs to be fixed through scleral walls, and the button loop of artificial iris is seen in limited space and the visual field, and the button loop of artificial iris is stretched next from scleral incision, are a very very difficult things.
It is accordingly required in particular to a kind of artificial iris with location hole, to solve above-mentioned existing problem.
The content of the invention
It is an object of the invention to provide a kind of artificial iris with location hole, for the deficiencies in the prior art, using the location hole of manufactured rainbow's waistband end, by location hook the button loop of artificial iris very easily from scleral incision it is stretched come, and pass through location hole with suture, the button loop of artificial iris is sewn to scleral walls, makes operation simple.
Technical problem solved by the invention can employ the following technical solutions to realize：
A kind of artificial iris with location hole, the end of the button loop of the artificial iris be provided be easy to using location hook button loop from scleral incision it is stretched come location hole.
In one embodiment of the invention, the shape of the location hole is including but not limited to being the geometries such as circular, square, rectangle or rhombus.
In one embodiment of the invention, the location hole is circle, its a diameter of 0.1-0.5mm.
Further, it is preferable that a diameter of 0.2-0.3mm of the location hole.
In one embodiment of the invention, the location hole is square, and its length of side is 0.1-0.5mm.
Further, it is preferable that the location hole is the square that the length of side is 0.2 × 0.2mm.
In one embodiment of the invention, on the location hole print or mark by way of be provided be easy under surgical operation microscope find button loop and location hole and the color different from button loop identification division.
Further, the color is including but not limited to redness, yellow, green, blueness, brown or white.
In one embodiment of the invention, the location hole is arranged on the end of the button loop of the artificial iris by way of punching after mould processing or shaping.
The artificial iris with location hole of the present invention, compared with prior art, in the button loop end locating and machining hole of artificial iris, and location hole printing or marked difference color, easily the location hole of artificial iris can be caught on using location hook, then the stretched scleral incision of button loop of artificial iris, location hole is passed through with suture, very easily button loop is sewn in scleral walls, plays a part of fixed artificial iris, realize the purpose of the present invention.
Of the invention the characteristics of, see the detailed description of this case schema and following preferable embodiment and is well understood to.
