Medical silicone is a widely used biological material in cosmetic surgery. It has various forms, such as: liquid silicone oil, foamed silicone sponge, and elastic solid silicone rubber. Solid silicone rubber is the most widely used. Silicone rubber has good bio-compatibility, no irritation, no toxicity, no allergic reaction to human tissue, and very little body rejection reaction; it has good physical and chemical properties, and can maintain its original properties during contact with body fluids and tissues. Elasticity and softness, is not degraded, is a fairly stable inert substance. It can withstand high temperature and can be sterilized. It is easy to process and form, easy to process and engrave shapes, and easy to use.
Silicone rubber is one of synthetic rubber, with chemical name of polymethylvinyl siloxane. It is polymerized by dimethylsiloxane monomer and other silicone monomers under the action of acid or alkaline catalyst, and the relative molecular weight is generally 400000-500000.
- Solid medical silicone rubber can replace bone or cartilage as tissue filling or scaffold material, so it can be made into artificial joints and artificial tendons to repair the defects of limb joints and tendons. Plastic materials are mostly used as materials for repairing deformities and defects of the face, ears, nose, etc.
- Foamed medical silicone rubber can replace the adipose tissue of the human body and repair the defects and deformities of the subcutaneous tissue of the human face, such as hemifacial atrophy.
- The film-type medical silicone rubber can be used as a substitute for tendon sheaths; the intestinal fistula inner plug is also made of this type of silicone, and its function is to seal the intestinal fistula in the intestinal cavity, prevent the leakage of intestinal fluid, and maintain the smoothness of the intestinal tract. Restoring enteral nutrition, reducing complications and simplifying the treatment of intestinal fistulas.
- Liquid medical silicone rubber, also known as silicone oil, is a low-viscosity transparent liquid. The silicone oil is injected into the craniofacial concave deformity using a thick injection needle. It is easy to use and can be shaped without hospitalization. In addition, medical silicone rubber is used to make hydrocephalus drainage device clinically to treat hydrocephalus. A spherical artificial heart valve is made to replace a damaged heart mitral valve. As for the silicone contraceptive ring, it has the advantages of safety, convenience, reliability and long-term effect. Silicone intravenous catheters, gastric tubes, and urinary catheters have light damage and little stimulation, and can be inserted into relevant parts of the human body for a long time. It has been widely used in clinical practice. application.
First of all, silicone rubber is a polymer medical material with excellent performance. It is used as an artificial material for medical use. It has relatively low cost, high practicability, is not prone to rejection, does not cause any harm to the human body, and has biological adaptability. Well, do not stick with the capillaries of the human body.
Secondly, silicone rubber products have such good medical properties, colorless, non-toxic, high temperature resistance, oxidation resistance, flexibility, and high transparency. .
In addition, it has coagulation properties; the toxicity test results meet the medical requirements; in clinical applications, it has good biocompatibility, no distorting effect, and no allergic reaction; it has excellent toughness and elasticity, good processing performance, and various processing methods. It is the material of choice for medical elastomer products; it has excellent abrasion resistance, soft touch, moisture resistance, and resistance to various chemicals.
Finally, silicone rubber products can also be used to make artificial heart valves, artificial lungs, bone adhesives, artificial skin, burn dressings, pacemaker insulation, sutures, various splints, catheters, grafts, trachea, Dental materials, insert materials, family planning supplies.
