Description

Moving bill {MOVABLE ARTIFICIAL EYE}

The present invention relates to a bill, and more particularly to a moving bill that can be used for a long time by reducing the likelihood of breakage or deformation of the orbital insert, can improve the movement.

An artificial eye is an artificial eye that is worn for normal impression and beauty in which one eye, and in some cases both eyes are injured in an eye disease or eye and is unable to recover visual function. Even if it is, it is necessary to lead a smooth social life without being aware of others' eyes without psychological lack.

This bill is divided into two categories.

If the blind eye is injured in the undamaged state, only the eye shape that is artificially expressed in the eye itself without visual acuity, for example, the iris, sclera, or blood vessel, is formed in the conjunctival sac of the human body. Wear it.

However, if the blinded eye can not be preserved, the eye is removed by inserting a spherical orbital implant to remove and replace the eye from the orbit through ocular extraction. At this time, the bill using the orbital implant is moveable structure, that is, the muscles around the orbital insert are grown and combined with the orbital insert to move similarly to the normal pupil according to the wearer's eye movement so that it looks like normal eyes. It is desirable to.

Orbital implants have been used in the manufacture of synthetic resins, glass, corals, and the like, and porous hydroxyapatite using corals is preferred because of its good biocompatibility. In other words, when the orbital implant is formed with a porous hydroxyapatite compared to the synthetic resin or glass, the growth rate of the biological tissue, that is, the degree of eye muscle growth inside the pores is increased.

1 is a view showing a state structure in which a conventional bill is worn on the wearer's eyes.

As shown in FIG. 1, in the conventionally used bill, a metal, for example, a metal material, for example, may be used to move the oval body 4 according to the movement of the orbital implant 1 composed of porous hydroxyapatite. Insert the screw (2) formed of titanium material, and insert the movement shaft (3) inside the screw (2).

Then, the orbital implant (1) and the eye (4) are formed by forming a groove (4a) into which the movement shaft (3) can be inserted into the rear of the eye (4) mounted and worn on the conjunctival sac (5). It is.

Here, the screw (2) is the time that the muscles of the eyeball grows and is coupled to the orbital insert (1) to move the orbital insert (1) with the muscle during eye movement, for example, about 6 months after ocular extraction After this, it will be inserted.

By the way, hydroxyapatite is excellent in biocompatibility, but requires a high cost in manufacturing, and poor sinterability, the mechanical strength is weakened when manufactured in a porous form having pores. Therefore, when the screw 2 is inserted into the orbital insert 1 made of porous hydroxyapatite, the orbital insert 1 of weak strength may be damaged.

In addition, as time elapses after the insertion of the screw 2, the portion into which the screw 2 is inserted may be disassembled and the shape may be changed, or the screw 2 may flow due to external force, or the orbital insert 1 may be damaged. there was.

Therefore, the burden of post-management and reoperation has been demanded.

The present invention is to solve and complement the problems caused by the conventional bill as described above,

An object of the present invention is to provide a moving bill that can be used for a long time by reducing the possibility of breakage or deformation of the orbital insert.

Another object of the present invention is to provide a moving bill that can improve the movement.

According to the present invention for achieving the above object, in the bill, Orbital insert which is inserted into the orbit of the human body; A support covering a portion of the orbital insert; And an eye shape disposed to cover the support and mounted on the conjunctival sac of the human body. It provides a moving bill including a.

The support may be provided with a protrusion protruding toward the eye shape, and the eye may be configured such that a groove is formed to insert the protrusion.

Grooves are formed in the support, and the eye-shaped body may be configured to have protrusions projecting toward the support to be inserted into the grooves.

The support and the eye body may be configured such that a magnet member or a magnetic member having opposite polarities are formed.

The frictional force between the orbital insert and the support may be configured to be greater than the frictional force between the support and the eye shape.

The ocular can be configured to cover a portion of the support.

According to the moving bill according to the present invention, there is an effect that can be used for a long time to reduce the likelihood of breakage or deformation of the orbital insert.

FIG. 2 is a view showing a state structure in which a moving bill according to a first embodiment of the present invention is worn on a wearer's eyes, FIG. 3 is a cross-sectional view showing a state in which a moving bill shown in FIG. 2 is worn. A photograph showing a support and an eye shape used in a moving eye according to a first embodiment of the present invention.

2 to 4, the moving bill 100 according to the first embodiment of the present invention is largely comprised of an orbital insert 10, a support 20, and an eye shape 30, which are indicated in the figure. Reference numeral "E" denotes an eyebrow of a human body.

The orbital insert 10 is a component that is inserted into the orbit of the human body as in the prior art, and is composed of porous hydroxyapatite having excellent biocompatibility.

The orbital insert 10 itself may be formed as a hydroxyapatite, but the orbital insert 10 is formed by using a synthetic resin, glass, ceramic, etc., and the hydroxyapatite is coated thereon to reduce manufacturing costs. You may.

The support 20 is a component that covers a portion of the orbital insert 10, which is a feature of the present invention. The support 20 is used when the ocular muscles of the eyeballs are coupled to the orbital implant 10 after about 6 months after ocular extraction and the orbital implant 10 can be moved together by the muscles during eye movement. Accordingly, the muscle may be located between the orbital insert 10 and the support 20 as shown in the figure.

The support 20 has a substantially hemispherical shape so as to correspond to the curvature of the orbital insert 10 to cover a portion of the spherical orbital insert 10. Since the support 20 is disposed in the human body of the wearer, it is preferable that the support 20 is formed through disinfection, for example, heat disinfection, so as not to harm the human body.

The support 20 serves to serve as a screw (2 in FIG. 1) and a motion shaft (3 in FIG. 1), which are conventionally used, ie, to connect the orbital implant 10 and the eye shape 30 described below. To this end, a protrusion 22 formed to protrude toward the eye shape 30 is provided. At this time, the surface of the support 20 and the orbital insert 10 is in contact with each other to form bumps, or the support 20 is formed by using a material with a large friction force, the support 20 along the outer surface of the orbital insert It is desirable not to flow easily.

In this way, the support 20 is disposed between the orbital insert 10 and the eye shape 30 to be connected, thereby reducing the foreign body feeling by dispersing the pressure caused by the eyelid of the wearer. In addition, by not using a screw (2 in Fig. 1) and the axis of motion (3 in Fig. 1) to reduce the likelihood of breakage or deformation of the orbital insert 10, the bill can be used for a long time and the weight of the bill (100) It can be reduced, and it is easy to work (surgery) and can shorten working time.

The eye body 30 is a component that is formed to be similar to the shape of the support 20 to cover the support 20, and is mounted on the conjunctival sac 200 of the human body and worn. The iris, sclera, blood vessels, etc. are artificially expressed in the eye body 30. A groove 32 is formed in the eye body 30 so as to correspond to the protrusion 22 of the support 20, and the groove 32 is slightly larger than the size of the protrusion 22 so that the protrusion 22 can be inserted. It is good to be formed as. Here, in FIG. 3, the eye-like body 30 is illustrated in such a size as not to contact the inside of the conjunctival sac 200, but according to the manufacturing environment of the eye 100 or the condition of the wearer wearing the eye 100. Upper body 30 may be formed to a size close to or in contact with the inner conjunctival sac 200.

It is good to configure the surface where the eye-shaped body 30 and the support body 20 contact smoothly. Because of this configuration, the frictional force between the orbital insert 10 and the support 20 is greater than the frictional force between the support 20 and the eye shape 30, so that the mobility of the orbital insert 10 that moves according to the eye movement of the wearer. It is well transmitted to the eye shape 30 so that the movement of the eye shape 30 can be improved.

On the other hand, the eye shape 30 to form a hole (not shown) in a fine size so that oxygen and tears can circulate to reduce the degree of deposition of proteins and the like attached to the eye shape 30 bill (100) ) Is good to use.

5 is a view showing a state structure in which a moving bill according to a second embodiment of the present invention is worn on the wearer's eyes.

As shown in FIG. 5, the moving bill 100 according to the second embodiment of the present invention has a configuration similar to that of the first embodiment described above, but unlike the first embodiment, a groove ( There is a difference in that 24 is formed, and protrusions 34 protruding toward the support 20 are formed in the eye-like body 30 and inserted into the grooves 24 of the support 20.

As such, the protrusions 22 and 34 and the grooves 24 and 32 formed in the support 20 and the eye shape 30 need to be connected to each other, so that the fabrication environment or the bill 100 of the bill 100 may be worn. It can be selected and formed according to the condition of the wearer.

6 is a view showing a state structure in which a moving bill according to a third embodiment of the present invention is worn on the wearer's eyes.

Referring to FIG. 6, in the third embodiment of the present invention, magnet members or magnetic members 26 and 36 having opposite polarities are formed on the support 20 and the eye shaped body 30 to be in close contact with each other.

That is, the magnet members 26 and 36 having opposite polarities may be formed on the support 20 or the eye 30, respectively, and the magnet member 26 or on the support 20 or the eye 30 may be formed. 36 may be formed, and the other may be used by forming a magnetic member 36 or 26 attachable to the magnet member 26 or 36.

These magnet members or magnetic members 26 and 36 are applied to the projections 22 and 34 and the grooves 24 and 32 formed in the support 20 and the eye body 30 of the first or second embodiment described above. The protrusions 22 and 34 and the grooves 24 and 32 may be configured as magnet members or magnetic members in close contact with each other.

On the other hand, the magnet member or the magnetic members 26 and 36 used are preferably plated, for example titanium ion plating to prevent harm to the human body to prevent corrosion when inserted into the human body. Do.

7 is a view showing a state structure in which a moving bill according to a fourth embodiment of the present invention is worn on the wearer's eyes.

As shown in FIG. 7, the moving bill 100 according to the fourth embodiment of the present invention is configured almost similarly to the moving bill 100 according to the first embodiment, and the shape of the support 20 is different from that of the first embodiment. It is different in that it is different.

That is, the support 20 used in the first embodiment is configured to be completely covered by the eye shape 30 so as not to be exposed to the outside. In contrast, in the fourth embodiment, since the size of the support 20 is larger than the size of the eye shape 30, the eye shape 30 covers only a part of the support 20 so that the support 20 is exposed to the outside. will be.

As such, the size of the support 20 may be configured differently according to the manufacturing environment of the bill 100 or the condition of the wearer who wears the bill 100.
