Mamma prosthesis containing air

Abstract

The mamma prosthesis features that it contains also gas phase. The mamma prosthesis is filled with colloid or liquid and gas is wrapped inside bulb in the gas-liquid or gas-colloid interface or inside special plastic bag. The bulb or plastic bag is in special shape, such as sphere, spheroidicity and crescent, or irregular shape. The gas may be nitrogen, clean air, some inert gas or other gas with no physiological harm and low chemical activity. The stuffing of the mamma prosthesis is smaller in specific weight, and simple and reliable in action mechanism.

Description

【Technical field】 [0001] The invention relates to a device in plastic surgery, in particular to a modeling prosthesis in plastic surgery. 【Background technique】 [0002] In the existing breast prosthesis, the bladder is filled with liquid or colloid. Due to the relatively large proportion of liquid or colloid, the entire breast prosthesis is heavy, and it is easy to fall when the human body is standing upright or walking, which greatly reduces the aesthetic effect of the breast prosthesis. Moreover, due to the force of the overall weight falling, it will cause strain on the capsule of the muscle fibers outside the breast prosthesis, thereby promoting the contracture and hardening of the capsule, affecting the natural shape and feeling of the breast prosthesis, and even causing pain to the recipient. cause more pain. [0003] Now some experts at home and abroad have noticed the problems in this respect and have made corresponding technical improvements. [0004] Domestic as...

Problems solved by technology

[0004] Domestic as Chinese patent 95213270.2 has announced a kind of combined breast prosthesis, and it is the breast prosthesis that is combined by multi-valve arc surface tetrahedron, and purpose is to reduce transplantation scar, makes muscle tissue can grow into the valve of breast prosthesis between the breast prosthesis, reducing the stimulation of the breast prosthesis to the capsule, and delaying the contracture and hardening of the capsule; but because it still uses a liquid or colloid with a large specific gravity, it cannot obviously eliminate the effect of the overall weight of the breast prosthesis. And other mechanisms of action are still difficult to determine, so there is no substantial improvement effect

[0005] Foreign such as U.S. Patent No. 5,480,430 announced a breast prosthesis filled with a double-layer capsule, which is characterized in that a special elastic structure is realized by using the double-layer capsule and the thickness distribution of the front, back, upper and lower capsules to achieve resistance. Contracture and maintain the natural shape and feeling of the breast prosthesis, but also due to the weight of the entire breast prosthesis, it is expected that it is difficult to achieve the set purpose

[0006] In addition, there is still a relatively related U.S. Patent No. 4,298,998, which discloses a double or multi-layer breast prosthesis with bioabsorbable breast prosthesis, which aims at the contracture and sclerosis that will occur after breast prosthesis implantation. A layer of bioabsorbable breast prosthesis film and filler is added to the periphery of the permanent inner capsule filled with gel or liquid. After implantation for a period of time, with the formation of the human tissue envelope, the bioabsorbable The breast prosthesis membrane and filler are also absorbed and degraded, so that the human tissue capsule maintains a flexible distance from the permanent inner capsule, so as to relieve the contracture pressure and sclerosis of the capsule; however, due to the bioabsorbable outer The material structure and source of the film and filler are not fully disclosed, and their physiological harmlessness, absorption mechanism, and physical and chemical characteristics of the shaped body are uncertain. Difficult to ascertain its actual effect
