▎ 摘 要
NOVELTY - The graphene pestle needle comprises needle head and needle handle. The front end of the needle handle connected with the needle, such that the needle has a set of heat conducting core, graphene heating film and shell. The heat conducting inner core and the needle head contacts the graphene heating membrane is connected with two electrode. Needle handle is provided with a power interface, and the electrode is electrically connected with the power interface. USE - Graphene pestle needle used as medical devices. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded view of the graphene pestle needle.
