Description
Technical field
This utility model relates to field of medical equipment, particularly relates to a kind of intraocular implant possessing stress deformation texture structure of observable stretcher strain degree.
Background technology
Iris belongs to eyeball middle level, in corpus ciliare front, has the size automatically regulating pupil, regulate and enter 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 work as ocular injury or eye congenital anomaly when causing aniridia or coloboma of iris, often there is the dysfunction of eyeball, as the increase of spherical aberration, aberration, low visual acuity after diplopia, dazzle, photophobia, amblyopia and wound, and visual acuity reduction etc.
Because the iris of atrophy does not make it regeneration by means such as medicines at present, the means of operation can only be adopted to repair.Conventional modus operandi has iris suture and artificial iris to implant.Iris suture is the elasticity of the normal iris tissue utilizing patient remaining, and being stretched by iris tissue is stitched together, and plays the effect of certain control light and restriction aberration.
At present, the major way of fixing intraocular implant has suture fixed form and button loop supporting way.
Suture fixed form is fixed by bundle of lines implant through after tissue by suture, but the limitation of said method is ophthalmic limited space, and stitching overlap joint is within the eye very difficult, and operation technique difficulty is large, and surgical effect is limited.
Button loop supporting way is in the space that a limitation is closed, button loop is used to withstand the end of enclosed space, play a supporting role, this modus operandi is simple, easy to operate, the pouch internal fixtion of such as intraocular lens, but the limitation of said method is to perform the operation in the space closed, and be not suitable for the fixing of the artificial iris at the place such as angle of anterior chamber or ciliary groove.
Existing artificial iris operation is fixed on remaining iris or iris root in sutural mode usually, or in ciliary groove, which needs to carry out complicated suture and knotting operation in space narrow, closed within the eye, operating difficulty is large, limit carrying out of operation, make the patient of numerous coloboma of iris can not get effective treatment.
In addition, because pathological changes and wound cause the patient of iris injury, often occur together lenticular disease or wound, not only there will be cataract, also may, with the pathological changes of crystal pouch or damage, the fixing difficulty of intraocular lens be increased.
Artificial iris and other implant many employings flexible materials, in implantation process, owing to being subject to the impact of various factors, causing implant when implanting, may not launch completely or in expansion process, stretching transition produces distortion, in former soft implant operation, these phenomenons often occur but all fail Timeliness coverage, even do not find, have impact on the performance of intraocular implant effect.
Therefore, special need a kind of intraocular implant possessing stress deformation texture structure, in operation process can Real Time Observation to the structure of soft implant minor variations, to solve above-mentioned existing Problems existing.
Summary of the invention
For overcoming the defect existing for prior art, a kind of intraocular implant possessing stress deformation texture structure is below proposed, utilize the texture structure on intraocular implant surface, can clearly, the real-time minor variations observed in intraocular implant implantation process, thus take corresponding treatment measures, avoid intraocular implant to launch not exclusively or the problem of stretching transition, give full play to the function of intraocular implant, and do not increase the difficulty of operation technique.
Particularly, the present invention relates to following content.
The invention provides a kind of intraocular implant possessing stress deformation texture structure, be provided with the texture structure that can show stress deformation on the surface of described intraocular implant or inside.
In one embodiment of the invention, described intraocular implant is including but not limited to: artificial iris, artificial amniotic membrane, corneal donor material and intraocular lens.
In one embodiment of the invention, described intraocular implant is including but not limited to the artificial iris of: band button loop, artificial iris not with button loop, the artificial iris of band intraocular lens and the intraocular lens of band iris diaphragm.
In one embodiment of the invention, the textural shape of described texture structure is 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 0.2mm2-0.3mm2.
