It should refer to medical silicone. Silicone rubber is a kind of synthetic rubber, and its chemical name is polymethylvinyl siloxane. It is polymerized by dimethylsiloxane monomer and other silicone monomers under the action of acidic or alkaline catalyst, and its relative molecular weight is generally 400,000 ~ 500,000. Medical silicone is a biological material widely used in cosmetic surgery, which has many forms, such as liquid silicone oil, gel-like silicone oil, foam silicone sponge and elastic solid silicone rubber. Solid silicone rubber is widely used at present.

characteristic

1、

Solid medical silicone rubber can replace bone or cartilage as tissue filling or scaffold material, so it can be made into artificial joints and tendons to repair the defects of joints and tendons in limbs. Plastic materials are often used to repair facial, ear and nose deformities. 2、

Foamed medical silicone rubber can replace human adipose tissue and repair facial subcutaneous tissue defects such as hemifacial atrophy. 3、

Thin film medical silicone rubber can be used as a substitute for tendon sheath; The internal plug of intestinal fistula is also made of this silica gel. Its function is to seal the intestinal fistula in the intestinal cavity, prevent the leakage of intestinal fluid, keep the intestinal tract unobstructed, restore intestinal nutrition, reduce complications and simplify the treatment of intestinal fistula. 4、

Liquid medical silicone rubber, also known as silicone oil, is a transparent liquid with low viscosity. Injecting silicone oil into the deformed part of craniofacial depression with a thick injection needle is convenient to use, can be shaped, and needs outpatient treatment without hospitalization. In addition, the hydrocephalus drainage device made of medical silicone rubber is used to treat hydrocephalus in clinic. A spherical prosthetic heart valve was used to replace the damaged mitral valve. As for the silicone contraceptive ring, it has the advantages of safety, convenience, reliability and long-term. Silicone venous indwelling needle, gastric tube and urinary catheter have the advantages of light injury and little irritation, and can be inserted into relevant parts of human body for a long time, which has been widely used in clinic.
