 Vacuum molding method of artificial implant for plastic surgery and its mold {Plastic surgery artificial step elder brother scandal vacuum formation method}

The present invention relates to a vacuum molding method and a mold of the artificial implant for molding surgery, and more particularly in the method of molding an artificial implant using a pair of molds when the upper mold having the wound model and the intaglio mold are combined A mold for sealing the recess between the inner surface of the mold and the inner surface of the recess and forming the recess in a vacuum state through the air suction passage formed in the recess, and then injecting the silicon into the recess instantaneously through the silicon injection passage; It relates to a suction vacuum molding method of the artificial implant for molding surgery using the same.

In general, when any part of the body is inherently abnormally developed and a depressed part is formed, or any part of the body is depressed by an external factor such as a traffic accident in life, various types of plastic surgery to restore it to its original state This is done.

In addition, the plastic surgery to be performed for the same reason as described above allows the patient to reduce the foreign body as much as possible by using a customized implant for each patient, and at the same time, the skin is naturally displayed on the upper part of the implant after rapid recovery and cure.

In the present invention of these various types of implants will be described taking the manufacturing process of the forehead implants as an example.

1 is a head side view of the human body representing a patient in which the forehead is recessed (1), Figure 2 is a head side view of the human body with the implant (2) inserted in the forehead portion recessed.

Typically, forehead prosthesis is obtained by applying alginate to the recessed part while the doctor identifies the recessed part of the patient's forehead.

The intaglio mold thus formed is embossed with gypsum by an engineer to produce a wound model, wherein the wound model is formed with the forehead of the patient represented by embossing. Form)

Filled with wax on the recessed part of the wounded model in the state of producing the embossed wounded model as described above, and processing the wounded model to the shape of the ideal forehead desired by the patient, and then using the plaster, the wounded model formed as described above is fitted. Is to make a mold with a groove, remove the wax from the wound model, inject an appropriate amount of liquid silicone into the mold, press the mold while the wound model is assembled, and solidify at room temperature for 24 hours, and then remove the mold and the wound model. Obtain a prosthesis of the material.

The implants are then packaged and delivered to the doctor after the finishing process to smooth the surface. The surgeon uses the same implant as the patient's forehead.

However, the prosthesis formed as described above has the following problems.

First, by injecting liquid silicone into the mold in the manufacturing process of the prosthesis and pressurizing the annular model from the upper part, the internal silicon is solidified in a state filled in the recess, and the air existing in the recess in the process of solidification is completed. The surface of the solidified prosthesis is often unevenly formed by air because there is no space to be discharged. If the surface of the prosthesis is severe, the surface is smoothly formed by grinding the surface of the prosthesis by hand if the surface is new or fine. If the work is to be carried out separately, such a surface treatment process takes a very long time in the entire time required for the production of the prosthesis, resulting in inefficient work and long work time.

Secondly, the completed prosthesis as described above has a problem that occurs when the surface work is severely performed until the patient does not obtain an ideal forehead shape after surgery and requires reoperation.

Third, as described in the above manufacturing method, by injecting a certain amount of liquid silicone into the inside of the mold and pressing the annular model from the top, the bottom of the silicon is filled in the depression and the depression is raised to the top along the gap of the depression Completely implanted, solidified and commercialized as a result of the completed implant has a problem that the structure of the silicon is not dense.

This problem forms the tip of the implant as thin as possible so that the patient does not feel foreign body and the implant is not felt from the outside.

In addition, the center of the depression (thickest part) has a high density of silicone, so as to feel a hard feeling compared to other parts, the patient inserting the implant has a problem such as complaints of discomfort by feeling foreign body.

Fourth, there is a problem that the thickness of the prosthesis is slightly different because the contact pressure is not uniform during pressurization due to the problem that the shape of the affected part is not constant. The sense of dissatisfaction can be said to be really great.

The present invention has been made in view of the above circumstances, and an object of the present invention is to manufacture a prosthesis comprising an upper mold having an affected part model and an intaglio mold having a groove into which the affected part model is inserted. In the mold, by implanting silicon while removing air in the recess formed in the mold, a prosthesis having a smooth surface is obtained, thereby significantly reducing the process of surface finishing work, thereby improving productivity and artificial prosthesis for molding surgery of high quality. The present invention provides a mold for vacuum forming that can be manufactured.

In addition, another object of the present invention is to provide a light and durable artificial implant to the end portion is formed by the same density of the inner portion to be processed thick and the end of the thin treatment to have a uniform structure. .

In addition, another object of the present invention to provide a new artificial molding method of the vacuum molding method using the molding for molding the artificial implant as described above.

In order to achieve the above object, the present invention creates an intaglio pattern of an indented portion using alginate on the indented portion of the patient, and casts plaster on the inner surface of the indentation to make the indented portion of the patient embossed. It has an upper mold formed with an annular model filled with wax or paraffin and a recessed groove corresponding to the annular model of the upper mold, and the air suction path and the silicon injection so that the inner surface and the bottom surface of the recess communicate with each other.

On the other hand, by using the mold configured as described above to create a negative pattern of the recessed portion using the alginate on the recessed part of the patient and cast plaster on the inner surface of the bone to produce a wound model embossed part of the patient And filling the wax or paraffin in the depression of the embossed wound model to restore the depression, and simultaneously thinning the wax or paraffin at the end of the depression, and the wound of the wax or paraffin coated relief Placing gypsum on the surface of the model to produce an intaglio mold, and removing the wax or paraffin of the embossed mold and combining the embossed mold and the intaglio mold using air suction holes formed in each mold in a sealed state. Removing air to form a vacuum state, and using silicon injection holes formed in the respective molds to Provided is a vacuum molding method of a novel artificial implant for molding surgery comprising the step of injecting and solidifying at room temperature and sterilizing and packaging the finished silicone implant formed in the depression in a clean room.

Here, the method may further include forming a plurality of holes through which skin tissue penetrates on the surface of the solidified silicon implant.

In addition, it provides an artificial implant produced by using the vacuum molding method as described above.

As described above, the molding for artificial implant vacuum molding according to the present invention and the molding method using the same have the following effects.

First, the silicon injection is quick and dense by injecting silicon in the vacuum state by removing the air inside the mold by using the air suction tube and the silicon injection tube formed in the engraved mold in a state where the three molds and the engraved mold are combined. By producing a solid implant, there is an effect that can produce an excellent quality implant that does not damage the tip of the thinly formed implant.

Second, by injecting silicon in the state that the air inside the mold is removed, a smooth surface can be obtained by not generating bubble marks generated on the product surface by the existing air. It has the effect of reducing the time and thereby improving productivity.

Third, due to the minimal finishing work, it is possible to produce the state of depressions measured from the first patient with minimal deformation, so that foreign body feeling disappears after the procedure and the depression is exactly matched to the depression so that the patient's satisfaction can be greatly improved. There is.

Hereinafter, a specific embodiment of the vacuum molding mold of the artificial implant for molding surgery according to the present invention and the manufacturing method of the artificial implant by the mold will be described with reference to the drawings.
