(Summary description)Application of low-temperature plasma surface treatment equipment in cardiovascular stents and intraocular lenses: The urinary catheters and infusion sets in interventional instruments with low-temperature plasma surface treatment equipment have been introduced before. The biocompatibility and material bonding performance have been greatly improved, which can effectively reduce the actual clinical application of interventional instruments. The accident rate in the application. Therefore, what is the use of low-temperature plasma surface treatment equipment technology in implantable medical devices? This article mainly introduces two typical cardiovascular stents and intraocular lens devices. The processing technology of the low-temperature plasma surface treatment equipment improves the uniformity and durability of the cardiovascular stent drug coating: Almost all implantable biomaterials and related devices can be directly used in the human body, so they must have biocompatibility, such as cardiovascular stents and other materials that directly contact the blood must also have blood compatibility, so they will be used in the cardiovascular system. The surface of the stent is coated with a drug coating. The use of low-temperature plasma surface treatment technology can improve the bonding ability between the stent and the film. The main method is to use low-temperature plasma surface treatment technology to perform plasma treatment on the stent, which can improve the wettability of the stent surface and increase the adhesion. Make the medicinal film more uniform and firm. The treatment technology of the low-temperature plasma surface treatment equipment improves the hydrophilicity of the intraocular lens and effectively solves the postoperative inflammation problem: PAM intraocular lens is a new type of soft material with good diopter and flexibility, and its surface is highly viscous, can produce strong adhesion to the posterior capsule, and can effectively promote the migration and proliferation of lens epithelial cells. Reduce the occurrence of posterior capsule turbidity. However, the PAM material is highly hydrophobic and easily adsorbs bacteria and cells, resulting in postoperative inflammation. In order to improve the reliability of the intraocular lens and prevent inflammation, all current low-temperature plasma surface treatment equipment adopts the low-temperature plasma surface treatment process, and the corresponding process modification is used to increase its surface energy and improve its infiltration performance. Chengfeng Zhizao uses low-temperature plasma surface treatment technology to actively cooperate with customers to carry out research on the surface modification of medical polymer materials and surface film synthesis to solve the problem of anticoagulant, biocompatibility, surface hydrophilicity, anti-calcification and Key technical issues such as cell growth and inhibition.
