Description: Patent: ZL201810381524.8; ZL201810381592.4; ZL201810237282.5; ZL201910334407.0; ZL201910335160.4; ZL201910335157.2; ZL201811498740.7; ZL201921098514.X; ZL201820348716.4; ZL201820064331.5.

This project focuses on original R&D of key technologies and a series of products for graphene-based anti-infection precision interventional devices, corresponding to ten nationally authorized patents. These patents cover innovations such as a graphene oxide-based thrombus removal shield needle, a graphene cardiovascular stent, a graphene hair follicle physiotherapy needle, a graphene acupuncture needle, a graphene laparoscope, a graphene precision drug delivery device, an intelligent topical drug delivery device, and a graphene physiotherapy wave chamber. Leveraging the exceptional antibacterial, anti-infection, and biocompatible properties of graphene oxide, the project addresses core challenges in conventional interventional devices, such as significant trauma, high infection risk, and single-functionality, thereby establishing a comprehensive technical system. The products are widely applicable in diverse scenarios including cardiovascular and cerebrovascular interventions, minimally invasive surgery, and traditional Chinese medicine physiotherapy, demonstrating outstanding clinical value, notable economic and social benefits, and strong prospects for international adoption.
