Description

Artificial eye piece

Technical Field

The utility model belongs to II types of medical instrument fields particularly, relate to an artificial eye piece.

Background

The artificial eye is a man-made artificial eye. Wearing the artificial eye does not restore the vision of the patient, but is a remedy for the facial defect. Therefore, the ocular disability or loss caused by some accidents and malignant diseases can improve the appearance by installing the artificial eye. Currently, the artificial eye materials are in various layers, such as glass artificial eyes, polymer artificial eyes, crystal artificial eyes and the like. The most used is polymer artificial eyes, and according to statistics, the artificial eye sheets are customized by using polymer materials in more than 95% of the countries all over the world at present. Glass artificial eyes, ceramic artificial eyes and other materials are gradually eliminated from the market.

The artificial eye piece is used for removing the eyeball of a human body or placing the conjunctiva of the eye in severe atrophy to play the roles of filling, supporting and beautifying. The shape is different, the size is different, the thickness is thin and thick, and the weight of the large eye patch is in direct proportion to the weight of the thick eye patch. When the patient wears the large and heavy eye slice for a long time, the orbit of the patient is deformed due to excessive compression, the eyelid is loose and drooped, the artificial eye slice cannot be arranged in the orbit of the patient with serious symptoms, and the artificial eye slice can be worn only by correcting the eyes through an operation.

Disclosure of Invention

To the artificial eye piece that prior art exists, can lead to the fact the eye socket to warp because of the overweight is compressed for the patient because of big thicknessly, the eyelid slack is flagging, can't settle the artificial eye piece in the serious person's eye socket, need correct the problem that the eye just can wear the artificial eye piece through the operation, the utility model provides an artificial eye piece that weight is lighter can solve the artificial eye piece among the prior art heavier to wearing patient's eye socket oppress for a long time and cause the deformation and lead to the eyelid slack and flagging, can't settle the artificial eye piece, need correct the problem that the eye just can wear the artificial eye piece through the operation.

In order to realize the technical purpose, the utility model discloses a technical scheme as follows:

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

As shown in fig. 1-6, an artificial eye piece comprises a sclera matrix 1 and an iris 4, wherein the sclera matrix 1 is hemispherical, a hemispherical groove 2 is reserved on the inner side of the sclera matrix 1, and a cavity 7 is reserved between the groove wall of the hemispherical groove 2 and the spherical surface of the sclera matrix 1; the iris 4 is fixedly embedded in the spherical center of the sclera matrix 1, the pupil 9 is fixedly embedded in the inner center of the iris 4, and the connecting seat 8 fixedly connected between the inner side of the iris 4 and the outer side of the hemispherical groove 2 is arranged in the cavity 7.

Wherein, connecting seat 8 includes connection piece 801, spliced pole 802 and tubaeform connection shell 803, connection piece 801 fixed mounting be in cavity 7 closes on the chamber wall of hemispherical groove 2, spliced pole 802 an organic whole sets up connection piece 801 dorsad on the side of hemispherical groove 2, tubaeform connection shell 803 fixed mounting be in spliced pole 802 is kept away from the one end tip of connection piece 801, just tubaeform connection shell 803 dorsad the one end of spliced pole 802 with iris 4 is towards a side fixed connection of cavity 7. The connecting seat 8 that above-mentioned technical scheme set up comprises connection piece 801, spliced pole 802 and tubaeform connection shell 803 for connecting seat 8's connection effect is better, can avoid connecting seat 8 to drop from between iris 4 and cavity 7, and especially important can guarantee connecting seat 8 to iris 4's support effect.

Specifically, the notch of the hemispherical groove 2 is integrally provided with an annular limiting ring 3, and the section of the annular limiting ring 3 is circular. The annular limiting ring 3 arranged in the technical scheme can prevent the artificial eye piece from falling off from the artificial eye eyeball.

The spherical surface of the sclera matrix 1 is also provided with an annular black area 5 on the outer ring of the iris 4. The annular black area 5 arranged by the technical scheme has the effect of beautifying the pupil, so that the artificial eye piece has a makeup beautifying effect.

The outer ring of the spherical surface of the sclera matrix 1, which is positioned in the annular black area 5, is provided with artificial blood filaments 6 which are distributed annularly. The artificial blood silk 6 arranged by the technical scheme ensures that the artificial eye piece is more vivid and closer to a real eye, thereby increasing the confidence of a patient.

The cavity 7 is also filled with nitrogen as a protective gas. The nitrogen gas that above-mentioned technical scheme set up has better protection effect to this artificial eye piece, can prevent this artificial eye piece by the oxidation to guarantee the life of this artificial eye piece.

The working principle is as follows: according to the artificial eye piece, the cavity 7 is reserved between the groove wall of the hemispherical groove 2 and the spherical surface of the sclera substrate 1, so that the weight of the artificial eye piece can be greatly reduced, and the problems that the artificial eye piece in the prior art is heavy, the eye socket of a patient is pressed for a long time to deform, the eyelid is loose and sagged, the artificial eye piece cannot be arranged, and the artificial eye piece can be worn only by correcting the eye part through an operation can be solved; in addition, be equipped with connecting seat 8 between the inboard and the hemispherical recess 2 outside of fixed connection 4 irises in cavity 7, connecting seat 8 effectively supports iris 4, can avoid iris 4 to appear the problem of indent easily.
