Typically, a bill is a pseudo-eye that is worn for normal impression and beauty when one eye is injured in an eye disease or eye and cannot recover vision. It plays the role of an artistic eye ball that is necessary to lead a smooth social life without pleasing the eyes of others without psychological deficits.

In general, a bill is a kind of artificial eye to make a third person free from disgust by making and wearing the eyes of a person who has injured or innately lost one or both eyes in the shape of healthy eyes. As a result, it is required to have a comfortable daily life.

In addition, the bill is for people who have undergone ocular extraction surgery due to lesions or trauma to the eyes or the area around the eyes, those who are congenital or acquired, who have no vision due to atrophy or development of the eye, and who cannot expect to recover their vision. It is used to enhance the protection of the orbit, to maintain the formation of the orbit, to promote the development of the skeleton, and to make the appearance look more beautiful than normal eyes.

On the other hand, the cloudiness or light atrophy of the cornea, even if blindness, is not significant damage to the eyeball can be made into a light and thin bill, so that the wearer can wear without great inconvenience, but the sclera, the thickest membrane surrounding the eye, is lost a lot. Orbital extraction (暇 球 摘 出) due to the volume of the orbit (眼窩) is turned on to increase the volume of the bill to be applied to it.

As described above, the bill used when the volume of the orbit increases due to scleral damage or ocular extraction is generally made of a synthetic resin used as a material for producing dentures and the like in dentistry.

As in Figure 1, the eye consists of the cornea, iris, lens, optic nerve, and the like. The cornea functions as a protective barrier protecting the eye with transparent avascular tissue on the outermost side of the eye and acts as a window that refracts light rays and reaches the retina. The iris is located between the cornea and the lens and the color of the iris may be racially and personally different. The pigment appears to be brown when there are many pigments and blue when there is little pigment, and serves as an aperture controlling the amount of light. The lens is a colorless and transparent structure in the form of a magnifying glass with two convex sides, which is behind the iris and is the main refraction organ of the eye with the cornea.

When the eye is extracted from the eye having such a structure, an ocular implant is inserted, an ocular prosthesis is inserted into the conjunctival sac of the orbit where the cornea and iris are located, and the eye is shrunk or In case of poor development, only the eye is inserted into the conjunctival sac of the orbit.

In this way, the bill must be inserted into the conjunctival sac portion of the orbit and closely adhered to the eye. Therefore, the bill must be formed to correspond to the shape of the individual conjunctival sac portion, and the shape of the pupil must be the same as the real eye of a normal person. It should be formed as close as possible to the normal eye on the other side of the to improve the fit and minimize the appearance disparity.

However, the conventional bill has a long manufacturing process of the bill, the mass production of the bill is impossible, the process is complicated, and it is impossible to manufacture pupils and iris portions of various sizes.

Therefore, the present invention is prepared by manufacturing a cylindrical iris portion in which the pupil part is inserted into a mold, and then cutting into a disc of a desired thickness, and then making a different sclera part according to the individual and combining the sclera part at the upper part of the sclera part. Most of these will be finished to provide a bill that shortens the manufacturing process of the bill.

Also, unlike the general bill, the pupil part and iris part of the bill are manufactured and mass production is possible, and the process improvement effect is achieved, and the pupil part and the iris part of various sizes are manufactured by adjusting the diameter of the pupil part and the iris part. It is also intended to provide a bill that is readily available to manufacture.

After the addition of the resin made in the gel state by dividing it into the upper frame and the lower frame in the same way as the other steps, place the disc in the center of the lower frame, and then fill the space inside the lower frame with the resin of the gel state When the gel resin is cured in the sclera part of the sclera, the upper mold and the lower mold are tightened with bolts and nuts, placed in a boiling point sterilizer and heated, and naturally cooled at room temperature after the heating operation to demold the cured resin. It is a method of manufacturing a delicate eye, characterized in that the completion of the eye of the combination of the pupil part, iris part, sclera.

In other words, the present invention is manufactured by manufacturing a cylindrical iris portion into which the pupil part is inserted into a mold, and then cut into a disc of a desired thickness to make a different sclera part according to the individual, and then simply combine it in the upper part of the sclera part. As most of these are finished, the manufacturing process of a bill is shortened much.

In particular, the boundary portion of the iris portion adjacent to the sclera is cut by chamfering, so that the circumferential portion of the primary molded product is overlapped with the sclera in the third step, so that the boundary line between the iris portion and the sclera portion and the surrounding concentric circles It is characterized by being naturally expressed in a similar shape.

Referring to the accompanying drawings, the manufacturing method of the bill according to the present invention for achieving the above object in detail as follows.

1 is a virtual side view before the insert according to the present invention into the eye of the patient, Figure 2 is a cross-sectional view of the manufacturing of the primary molded article for making the pupil portion and the iris portion of the bill according to the present invention, Figure 3 Fig. 4 is a cross-sectional view of a manufacturing method of a bill made of a cornea covered with a sclera portion covered in the grinding portion of the pupil and the iris portion of the bill.

The first step of the present invention is to prepare the pupil portion of the bill into a black or transparent cylindrical shape.

In order to make the pupil part of the bill, gypsum mold is made by using a mixture of pumice gypsum and water. After manufacturing the lower mold, apply a separating agent to the model of the pupil part and then horizontally in the center of the upper part of the lower mold. Insert the mold into the bottom frame is completed. And in the same way it is repeated again to manufacture the upper frame.

Gypsum mold is completed in the same way as above, when the lower mold and the upper mold is fastened with bolts and nuts provided on the left and right sides, and the plaster mold is compressed by pressing, and the air in the plaster mold is discharged to provide more precise parts. It is possible to manufacture.

The next process is to remove the model of the pupil part of the bill pupil portion from the upper frame and the lower frame, and then apply an acro sep to the upper frame and the lower frame.

Polymethylmethacrylate (PMMA), which is inserted between the upper frame and the lower frame and used as a material of the bill after curing, is known to be aesthetically and clinically most suitable as a material of the bill and is widely used. It is an acrylic resin and used for pores. The acrylic resin PMMA is a liquid when the monomer and a polymer when the polymer is cured at room temperature in the form of a powder, which corresponds to an immediate polymerization resin, and the PMMA resin as the basis of the bill is a polymer. It is formed as a solid by polymerizing a liquid which is a powder and a monomer.

The resin inserted between the upper mold and the lower mold is mixed with a transparent acrylic resin powder in the form of powder and a monomer resin solution in the form of a solution by stirring with a spatula in a defensive dish for a predetermined time, and then left at room temperature for a predetermined time. The resin turned into a space in the upper mold and the lower mold is pressed by pressing the plaster mold with a press to release the air in the plaster mold and the resin.

When mixing the transparent acrylic resin powder and the monomer resin solution, black pigment may be added and mixed as necessary.

When the resin of the gel state inside the plaster mold is cured, the upper mold and the lower mold are tightened with bolts and nuts, and placed in a boiling point sterilizer for 1 hour and 30 minutes between 71 to 74 ° C. The secondary heating, which is further heated at 100 ° C. for 30 minutes, hardens the resin sufficiently and does not deform the shape in other processes.

After the heating operation, the resultant is naturally cooled at room temperature to demold the cured resin, thereby completing a primary molded article of a cylindrical pupil part.

The cylindrical primary shaped article is polished to have a uniform outer circumferential surface and to smooth its surface.

The cylindrical pupil portion has a diameter of about 1 to 5.5 mm, but the standard diameter is set to 3.5 mm.

In the second step of the present invention, as shown in FIG. 2, the iris portion is manufactured in a cylindrical shape concentrically on the outer circumference of the pupil portion, and the pupil portion is a process of manufacturing a primary molded product inserted into the iris portion.

First, a transparent acrylic resin powder, which is a PMMA resin multimer, and a PMMA resin monomer resin solution are mixed at a predetermined ratio to make a gel state.

In addition, black, red, and yellow pigments may be mixed with the transparent acrylic resin powder in an appropriate ratio in order to express an iris portion of a brown Asian, which is mainly brown, and then mixed with the resin solution to form a brown gel resin. .

Of course, the color of the resin may be expressed in various colors by selecting and mixing appropriate pigments according to different iris colors according to individuals and races.

As shown in Figure 2, the plaster frame for making the required size and shape is manufactured in the same manner as the upper frame and the lower frame of the previous pupil portion, and the pupil portion prepared in the first step in the center of the plaster frame After seating, the gel resin prepared by mixing the transparent acrylic resin powder and the acrylic solution is filled between gypsum molds, and the resin of the iris portion of the gel state is cured, and the upper mold and the lower mold are fixed with bolts and nuts. The gypsum mold is placed in a boiling point sterilizer and heated firstly for 1 hour 30 minutes at a temperature of 71-74 ° C., and then heated twice while boiling at 100 ° C. for 30 minutes when the gypsum mold starts to boil in a boiling point sterilizer. .

After the heating operation and the natural cooling at room temperature to demold the cured resin and then polishing to produce a cylindrical shape in which the pupil portion and the iris portion are combined, the cylindrical shape is cut into a disc of a predetermined thickness, and then the turning The primary molded part of the grinding process is completed by chamfering the edge of the finished disc.

Grinding of the corners of the primary molded product in the form of chamfering is carried out so that the sclera part naturally overlaps the iris part in the next three steps.

It is preferable that the primary molded article made of the disc has a diameter of about 9 to 15 mm, but the standard diameter is 11.5 mm and the thickness is about 0.5 to 1.5 mm, which varies depending on the individual.

The second step of the manufacturing method of the present invention is manufactured in a cylindrical shape in which the pupil part and the iris part are combined and cut into a disc having a predetermined thickness, which is manufactured in a state in which the pupil part and the iris part are combined in a different state from the conventional bill, and mass production. This is possible, and the effect of the process improvement occurs, and if the manufactured by adjusting the diameter of the pupil portion and the iris portion of the primary molded product is characterized in that the pupil portion and iris portion of various sizes can be easily produced.

In the third step of the present invention, the primary molded article composed of the pupil part and the iris part is seated on the upper part of the scleral part to prepare a bill herbaceous herb.

First, in order to express a white index sclera, an opaque acrylic resin powder, a monomer resin solution, and a white pigment are added to make a resin in a gel state. Prepare in the same manner as in step 2, but only in the shape of the inside of it, and seat the primary molded part in a certain portion of the lower frame, but the corner portion of the primary molded product is seated so that the ground part chamfered Filling the prepared resin of the gel in the lower mold, but filling the corners of the primary molded article chamfered so that no bubbles are generated, and then covering the upper mold to harden the resin in the gel state. Fix the mold and the lower mold with bolts and nuts, put the plaster mold in a boil sterilizer and heat it for 1 hour 30 minutes at a temperature of 71-74 ° C., and then When the plaster mold begins to boil in the sterilizer, heat it for 2 more minutes at 100 ° C.

After the heating operation, the gypsum mold is naturally cooled at room temperature, and the cured resin is demolded in the gypsum mold to complete a bill herb combining the pupil part, the iris part, and the sclera part.

Grinding of the corners of the primary molded product by chamfering is to naturally realize the boundary between the iris and the sclera. In the conventional proposal, the boundary between the iris and the sclera is clearly distinguished and compared with the human eye. Although the feeling of the bill is strong, the bill of the present invention is made so that the sclera part covers a part of the iris part, the boundary area becomes unclear so that it is realized very similar to the eyeball of the human body.

In other words, the white opaque sclera is made to cover a certain portion of the iris portion having a transparent or specific color, so that the color of the overlapped portion becomes a shape similar to the actual eye, resulting in an increase in the quality of the bill.

Preferably, the sclera portion covers a portion of the iris portion so that the width of the sclera portion is 0.2 to 1.0 mm. When the sclera portion is smaller than the numerical value, the boundary of the boundary portion becomes clear, and the iris portion is larger than the numerical value. This is because it is so small that it can be opposed by the viewer.

For the same reason as above, in the second step of the manufacturing method of the present invention, the edge of the primary molded product is ground by chamfering, and in the third step, the surface of the ground edge of the primary molded product is seated at the bottom and no resin is generated. After filling up, proceed to the next step.

When the herbal by the above is completed, as shown in Figure 4, the bill is finished after polishing and coloring the cornea and the corneal part, and after the grinding and finishing process.

The finishing process for the completed bill is described below.

First, polish the bill's herb to color blood vessels or shadows of the sclera, but process the front of the bill with the iris as a reference point, and process the back with no rough or uneven parts at the deepest point.

Next, an iris, sclera, and blood vessels are formed on the front surface of the bill resin using acrylic color paint, silk fiber, and the like, which are commonly used to have the same color as normal eyes.

The silk yarn is bonded with an acrylic adhesive, and an acrylic adhesive and a resin solution such as PMMA liquid resin are used.

When the blood vessels of the eye are expressed, the red silk yarn is arranged around the pupil in a blood vessel shape and implanted. It is better to implant the blood vessels on the inner eye side thicker than the blood vessels on the outer eye side.

Then, as shown in Figure 4, in order to cover the cornea portion of the medicinal herb to prepare a gypsum mold in the same manner as in the previous manufacturing step, and after seating the medicinal herb to the lower frame of the acrylic adhesive to the medicinal herb After applying the gel resin prepared by mixing transparent acrylic resin powder and resin solution in a certain ratio to the above-mentioned bill, and then curing the resin in the gel state, the upper frame and the lower frame were bolted and nuts. By fixing, the first and second heating steps carried out in the previous manufacturing step is performed. Then, by demolding the product to perform the finishing process such as polishing and polishing work, the bill of the desired shape is completed.

Therefore, the present invention is to produce a primary molded article by manufacturing the iris portion in a cylindrical shape on the outer periphery of the cylindrical portion of the cylindrical shape in a cylindrical shape, cutting into a disc of a desired thickness, and make the sclera part different according to the individual Just by placing the upper part of the main process is mostly finished, so the manufacturing process of the bill is shortened much.

In addition, by manufacturing the primary molded article of the cylindrical shape in which the pupil part and the iris part are combined, the pupil part and the iris part of the bill are manufactured differently from the general bill, and mass production is possible, and the effect of process improvement is generated.

In addition, by adjusting the diameter of the pupil portion and the iris portion of the primary molded article it is also possible to easily manufacture a pupil portion and iris portion of various sizes.

In addition, the subject matter of the present invention is manufactured so that the sclera part covers a part of the iris part, the boundary area becomes unclear so that it is realized very similarly to the eye of the human body.
