Title: METHOD FOR PRODUCING AN ARTIFICIAL BREAST PROSTHESIS WITH A MINIMIZED CONCENTRATION OF STRESSES
Abstract:
The present invention relates to a method for producing an artificial breast prosthesis with a minimized concentration of stresses, and more particularly, to a method for producing an artificial breast prosthesis which has superior mechanical and physical properties, a pleasant feel, and a superior efficiency as a breast prosthesis. The silicone-filled artificial breast prosthesis produced by the method of the present invention has a shell with a constant thickness, and a silicone film bonding portion, to minimize the concentration of stresses which might be applied to a user after the breast prosthesis is placed in the body of the user, and to thus maximize the resistance against fatigue failure. The method for producing an artificial breast prosthesis with a minimized concentration of stresses according to the present invention comprises: a silicone solution application step (S100) of dipping a breast-shaped mold (10) into a silicone solution (20) to obtain an artificial breast shell; a drying and hardening step (S200) of drying and hardening the artificial breast shell attached to the mold using a drier (30) to obtain an artificial breast shell; an organic chemical solution spraying step (S300) of spraying an organic chemical solution onto the lower portion of the artificial breast shell using a microsprayer (40); an artificial breast shell acquisition step (S400) of forming a hole at the lower end of the artificial breast shell which is attached to the mold and chemically treated, and detaching the artificial breast shell from the mold; and a prosthesis-finishing step (S500) of attaching a silicone film (200) with a leakage prevention film to the hole formed in the previous step to close the hole. The present invention provides said artificial breast prosthesis in which the variation of the thickness of the artificial breast shell is eliminated to minimize the concentration of stresses and to maximize the resistance against fatigue failure, wherein the artificial breast prosthesis is thin and has a pleasant feel.
