Description
Technical field
This utility model belongs to armarium, is specially a kind of artificial cornea.
Background technology
The cornea of people is very tender and lovely, is the organ being very easy to damage. Once damage is difficult to spontaneous recovery, it is one of the oculopathy of the big blinding in the world three. As run into the pathological changes such as wound, chemical burn, corneal leukoma all because causing that corneal injury seriously cannot do corneal graft and blind.
The method that treatment keratopathy is best at present is to do live body corneal transplantation, due to the impact by traditional view and faith, it is extremely difficult for obtaining live cornea, currently can only do transplant operation with the cornea that volunteer contributes, but even if do the operation of one or many live cornea. Also blind because of factors such as rejections. The chance that existing domestic annual only about 4000 people can obtain live cornea and perform an operation. Other keratopathyes patient can only wait in the dark. Ten thousand people more than 400 is had according to the national blind association statistics whole nation blind person blind because of keratopathy in 2010.
These patients, cause losing the sight of both eyes because athletic injury, various burn or the various diseases of cornea self etc. repeatedly do corneal transplantation failure, its oneself through carrying out live cornea again, to transplant these patient optical fundus visual performances fair, only because cornea damages, to cause that light cannot enter eyeball internal and blind.
Utility model content
The purpose of this utility model is in that to provide a kind of artificial cornea, solves the problem in background technology.
This utility model realizes by the following technical solutions:
A kind of artificial cornea, including support deck, porcine cornea body, titanium alloy reticulated, through hole, concave surface, convex surface, one-level introduction segment, two grades of introduction segments, thread segment, revealed section, draw-in groove, described support deck and thread segment are threaded connection, described porcine cornea body is connected on support deck, described titanium alloy reticulated covers on porcine cornea body, described porcine cornea body is provided with through hole, two grades of introduction segments it are provided with on the left of described thread segment, it is provided with one-level introduction segment on the right side of described two grades of introduction segments, it is provided with concave surface on the left of described one-level introduction segment, it is provided with revealed section on the right side of described thread segment, the right side of described revealed section is provided with convex surface, it is provided with draw-in groove in described support deck, described one-level introduction segment, two grades of introduction segments, thread segment, the radial dimension of revealed section increases successively.
In this utility model, in described support deck, it is provided with draw-in groove.
In this utility model, described concave surface, convex surface, one-level introduction segment, two grades of introduction segments, thread segment, revealed sections are arranged point-blank.
In this utility model, described concave surface is sphere, and its spherical radius is 9.5-35.5 millimeter.
In this utility model, described convex surface is sphere, and its spherical radius is 6.4-8.5 millimeter.
In this utility model, the spherical radius of described convex surface is 7.4-7.5 millimeter.
Beneficial effect: this utility model by arranging concave surface and convex surface on mirror post, it is possible to make mirror post possess certain diopter, strengthen lighting angle, improve the angular field of view of patient, moreover it is possible to play the effect of correct vision; One-level introduction segment, two grades of introduction segments, thread segment, revealed sections are included by being designed as by mirror post, one-level introduction segment, two grades of introduction segments can make mirror post enter faster in carrier base, and the external screw thread of thread segment reaches the effect of fixed mirror post except the screw-internal thread fit played with carrier base.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of support deck of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
Referring to Fig. 1, Fig. 2, the structural representation of a kind of artificial cornea, the structural representation of the support deck of a kind of artificial cornea, a kind of artificial cornea, including support deck 1, porcine cornea body 2, titanium alloy reticulated 3, through hole 4, concave surface 5, convex surface 6, one-level introduction segment 7, two grades of introduction segments 8, thread segment 9, revealed section 10, draw-in groove 11, described support deck 1 is threaded connection with thread segment 9, described porcine cornea body 2 is connected on support deck 1, described titanium alloy reticulated 3 covers on porcine cornea body 2, described porcine cornea body 2 is provided with through hole 4, two grades of introduction segments 8 it are provided with on the left of described thread segment 9, it is provided with one-level introduction segment 7 on the right side of described two grades of introduction segments 8, it is provided with concave surface 5 on the left of described one-level introduction segment 7, it is provided with revealed section 10 on the right side of described thread segment 9, the right side of described revealed section 10 is provided with convex surface 6, described concave surface 5, convex surface 6, one-level introduction segment 7, two grades of introduction segments 8, thread segment 9, revealed section 10 arranges point-blank, is provided with draw-in groove 11, described one-level introduction segment 7 in described support deck 1, two grades of introduction segments 8, thread segment 9, the radial dimension of revealed section 10 increases successively, and described concave surface 5 is sphere, and its spherical radius is 9.5-35.5 millimeter, and described convex surface 6 is sphere, and its spherical radius is 6.4-8.5 millimeter. the spherical radius of described convex surface 6 is 7.4-7.5 millimeter.
Embodiment 1
So can making to secure the stand on eye cornea by performing the operation, afterwards mirror post is selected into support and play printing opacity effect, light can pass through mirror post and enter the inside of eyes, makes blind patient see light again.
