Description
Technical field
The present invention relates to field of medical equipment, more particularly, to a kind of intraocular implant possessing stress deformation texture structure of observable stretcher strain degree.
Background technology
Iris is belonging to eyeball middle level, in front of corpus ciliare, has the size automatically adjusting pupil, adjusts and enters the how many effect of ophthalmic light.As a kind of biologic soft tissue material, iris has the viscous-elastic behaviours such as delayed, lax, creep, strain rate dependency.
The important mechanical characteristic of iris makes it when ocular injury or eye congenital anomaly lead to aniridia or coloboma of iris, the dysfunction of eyeball often occurs, as the increase of spherical aberration, aberration, low visual acuity after diplopia, dazzle, photophobia, amblyopia and wound, and visual acuity reduce etc..
Iris due to atrophy can not be allowed to regenerate by means such as medicines at present, can only be repaired using the means of operation.Conventional modus operandi has iris suture to implant with 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 certain control light and the effect limiting aberration.
At present, the major way of fixing intraocular implant has suture fixed form and button loop supporting way.
Suture fixed form be pass suture through tissue after fixed by bundle of lines implant, but said method be limited in that ophthalmic limited space, suture within the eye overlap joint is extremely difficult, and operation technique difficulty is big, limited by surgical effect.
Button loop supporting way is in the space of a limitation closing, withstand the end of closing space using button loop, play a supporting role, this modus operandi is simple, easy to operate, fixing in the pouch of such as intraocular lenss, but being limited in that of said method can only be performed the operation in the space of closing, is not particularly suited for the fixation of the artificial iris in angle of anterior chamber or ciliary groove etc..
Existing artificial iris operation is generally fixed on the iris of remaining or iris root in the way of stitching thread, or in ciliary groove, which needs to carry out suture and the knotting operation of complexity in narrow within the eye, closing space, operating difficulty is big, limit the development of operation, so that the patient of numerous coloboma of iris cannot be effectively treated.
Further, since pathological changes and wound lead to the patient of iris injury, often occur together lenticular disease or wound, not only cataract occurs it is also possible to the pathological changes of crystal pouch or damage, make manually lenticular fixing difficulty increase.
Adopting flexible material artificial iris and other implants more, in implantation process, due to being affected by various factors, lead to implant implantation when, may not have fully deployed or launch during, stretching transition is deformed, in former soft implant operation, these phenomenons often occur but all fail to find in time, even without discovery, have impact on the performance of intraocular implant effect.
It is accordingly required in particular to a kind of intraocular implant possessing stress deformation texture structure, in operation process can Real Time Observation to soft implant minor variations structure, to solve above-mentioned existing problem.
Content of the invention
For overcoming the defect existing for prior art, a kind of intraocular implant possessing stress deformation texture structure set forth below, texture structure using intraocular implant surface, the minor variations in intraocular implant implantation process can be observed clearly, in real time, thus taking corresponding treatment measures, avoid intraocular implant to launch incomplete or stretching transition problem, give full play to the function of intraocular implant, and do not increase the difficulty of operation technique.
In particular it relates to content below.
The present invention provides a kind of intraocular implant possessing stress deformation texture structure, on the surface of described intraocular implant or be internally provided with the texture structure that can show stress deformation.
In one embodiment of the invention, described intraocular implant including but not limited to：Artificial iris, artificial amniotic membrane, corneal donor material and intraocular lenss.
In one embodiment of the invention, described intraocular implant including but not limited to：With button loop artificial iris, without button loop artificial iris, the artificial iris with intraocular lenss and with iris every intraocular lenss.
In one embodiment of the invention, the textural shape of described texture structure including but not limited to：Square, rectangle, rhombus, circle and triangle.
In one embodiment of the invention, the area of described texture structure is between 0.07mm2-0.5mm2.
Further, the area of described texture structure is preferably 0.2 mm2-0.3mm2.
In one embodiment of the invention, described texture structure is positioned close to the Zone Full of intraocular implant loading end edge 0.8-2mm or in certain specific region.
In one embodiment of the invention, described texture structure is processed in the surface of described intraocular implant or inside by way of including but not limited to the processing of laser ablation, printing and mould.
