Abstract

PURPOSE: The titled polyacrylamide hydrogel used as a substitute for human body tissue is provided, which has an effect on overcoming a defect such as heterogeneity and harmfulness to the human body and enables a patient to have a sense of satisfaction. CONSTITUTION: This polyacrylamide hydrogel is used as a substitute for human body tissue such as augmentation of breast and genitals, augmentation of human body tissue, skin wrinkles removal, contour correction and glass body of an eyeball. The substitute contains 1 to 20% by weight of polyacrylamide hydrogel, in particular preferably 3 to 4% by weight of polyacrylamide hydrogel.

Description

Polyacrylamide hydrogel used for antiwrinkling, reform, enlargement of body tissues including breast and pennis, and substitute of eye ball's vitreous}

The present invention relates to a polyacrylamide hydrogel used in facial tissue removal, contour correction, enlargement of human tissues including breast and genital enlargement and ocular vitreous substitute in the field of cosmetic surgery.

Recently, with interest in beauty and the development of medical technology, human tissue augmentation surgery including wrinkle removal, contour correction, breast and genital enlargement has been widely performed. In particular, women with poor breasts due to innate or diseased or malignant tumors are showing great interest in breast augmentation surgery. Conventionally, liquid silicone was used for breast augmentation by filling liquid silicone bag, but it was good to touch, but liquid silicone penetrated into human body when it burst by external shock, causing side effects such as autoimmune diseases. FDA has banned the use of liquid silicone. Since then, a bag containing high concentration of glucose gel has been used for breast augmentation, but there are also cases of enormous swelling and inflammation when cracking. Recently, saline bag is used mainly. However, saline sachets have no problems with safety, but texture and touch have a drawback that is too different from that of breasts, and the invention of new breast implants is a great need.

On the other hand, the vitreous is a transparent ball-shaped structure, which is a transparent material wrapped in a thin fibrous membrane, and is gel-like, very transparent, without blood vessels, and occupies the entire volume of the eye, which is important for the eye to maintain the shape of the ball. Play a role. The vitreous is responsible for ensuring that light reaches the retina safely. In patients with severe eye damage, the vitreous may leak and become blind. In this case, the patient's eyes have to lose sight because the damaged eye is removed and the artificial eye is implanted.However, when the transparent sphere is made by using polyacrylamide hydrogel inside the eye and replaced by an artificial vitreous body, the strength and shape are improved. Keep well. Although a method of injecting a silicon-based material into the artificial glass body has been developed, there are problems due to side effects of rejection. Polyacrylamide hydrogels, on the other hand, are safe for humans and can prevent blindness in patients with eye damage.

Therefore, it can be made similar to human tissue and can increase patient satisfaction, but it can be used as a material for human tissue enlargement and ocular vitreous substitute including facial wrinkle removal, contour correction, breast and genital enlargement using harmless polyacrylamide hydrogel. Invented so that.

The present invention uses a polyacrylamide hydrogel to make the implant almost similar in texture and texture to biological tissues. Since the viscosity of polyacrylamide hydrogel can be adjusted by controlling the concentration of acrylamide, the gel can be manufactured according to the firmness of skin, breast, genital, and ocular vitreous, which is different from patient to patient. In the case of artificial ocular vitreous treatment, the polyacrylamide hydrogel in a powder state is put in a pocket, and a technical wound can be converted into a gel state by injecting a solution after injecting a small wound. Since polyacrylamide hydrogel is almost harmless to human body, it can be used as a substitute for existing formulations for wrinkle removal or contour correction.

Polyacrylamide hydrogel is a mesh-type polymer made by cross-reacting acrylamide monomer with a polymerization reaction. At this time, the small amount of unreacted monomer is used as it is known to be harmful to human body as neurotoxin. In this way, the present invention forms a sponge-like structure between the cells of skin tissues through the amazing water molecule attraction, helping to maintain skin volume, cushion, skin moisturize, lubricate, heal wounds and metabolism of cells. Can give

Polyacrylamide hydrogel injected into human tissue with breast enlargement, genital enlargement, tissue enlargement, wrinkle removal, contour correction and ocular vitreous substitute can be used in 1 ~ 20% by weight depending on human tissue, especially 3 to Viscosity of 4% by weight is preferred. When polyacrylamide hydrogel is used as a tissue enlargement, wrinkle removal, contour correction and ocular vitreous substitute, including breast enlargement and genital enlargement, it can be used by direct injection method. It can be injected into human tissue by the procedure. In case of injecting into pouch, polyacrylamide is powdered into breast pocket and vitreous bag, and then put into breast and eye, and then injected into liquid to gel state. It has the advantage of being small.

That is, the polyacrylamide hydrogel used in the present invention may be used as it is in a gel state, and in a powder state, and the polyacrylamide hydrogel used should be free of neurotoxins known as neurotoxins, and may be directly injected. It can also be used in.

Polyacrylamide hydrogel through the present invention when used as a tissue replacement procedure and ocular vitreous substitutes, including facial wrinkle removal, contour correction, breast and genital enlargement in the field of molding and the heterogeneity of the conventional formulations It has the effect of overcoming harmful shortcomings.
