The Medical Application And Development Of Silicone
🕙 2023-08-11 👆
Nearly 20 years, the global silicone rubber products at a rate of more than 15% per year rapid development, the current global silicone market size has reached 6 billion US dollars, silicone as a medical material after decades of clinical application, has been recognized by the medical community, more and more widely used, many large companies to medical silicone as the main goal of development, medical silicone has made great progress.
Application status
In addition to meeting the basic requirements of medical polymer materials, silica gel also has the characteristics of heat resistance, cold resistance, non-toxic, biological aging resistance, minimal reaction to human tissue, good physical and mechanical properties, etc., becoming a typical medical polymer material, widely used in medical health, biomedical engineering fields, in the current many medical polymer materials, Silica gel dominates both in quantity and variety.
◆ Conduit
Medical catheter is the fastest growing and most widely used product in medical silicone products. According to the use can be divided into in vivo and in vitro, in vitro is mainly all kinds of pump tube, such as artificial heart-lung machine pump tube, and various instruments connection tube, infusion tube and so on; Used in the body are various intubations, catheters and drainage tubes. At present, the development trend of medical catheters used in human body is miniaturization, thin wall, multi-cavity and multi-function of one tube. Especially for catheters in the body, whether for long-term or short-term use, the advantages of silicone rubber materials and catheters are unmatched by other materials.
◆ Brain surgery products
Silicone products for craniocerebral surgery are mainly: Artificial skull, silicon-titanium composite repair materials, hydrocephalus division device, cerebral ventricle drainage tube, artificial meninges. Currently, the artificial meninges made of silicone rubber and nylon fabric developed in China can be used to repair traumatic dural defects, and repair dural or dural defects caused by resection of tumors in the dural base or infiltrating area.
◆ ent products
Silicone products used in ent department include: artificial nose bridge, artificial jaw, mandible, artificial ear, artificial throat, otitis media vent, lacrimal passage probe device, lacrimal passage plug, nostril stent, stop snoring device, nasal hemostatic balloon, artificial ventilator wave tube, tracheotomy tube, etc. At present, silicone rubber has been widely used in plastic surgery and prosthetics, which can repair various parts of the face and internal organs, chest, joints, etc.
◆ Cardiac surgery products
The silicone products used in cardiac surgery mainly include pump tube of extracorporeal circulation machine, thoracic drainage tube, silicone membrane of artificial lung, spherical mitral valve of artificial heart, etc.
◆ Digestive system products
Silicone stomach tube, duodenal tube, double cavity intestinal cannula, nutrition tube, gastric decompression tube, gastrostomy tube, gastric lavage tube, enema, etc. Previously, these products mainly used PVC materials, with the reduction of silicone production costs, and silicone rubber products, softness and elasticity are more ideal, so at present, a large number of PVC products have begun to replace in China.
