Abstract

See full text

The present application relates to a monopolar electrode and a bipolar electrode that are used for electrosurgical instruments. The monopolar electrode and the bipolar electrode each include a conductive non-stick coating which is made by doping graphene and/or metal particles in a PTFE (polytetrafluoroethylene) base material. The present application also relates to a preparation method of a composite material forming the conductive non-stick coating. Since PTFE itself can prevent adhesion, the conductivity of PTFE can be improved by doping various conductive materials. After the composite material coating formed thereby covers a metal electrode, it is ensured that the working region and work energy of an electrotome are not reduced, the electrical conductivity of the electrode can be guaranteed, not only the blood coagulation effect of the electrotome is not affected but also the adhesion of the electrode on a tissue can be reduced. Furthermore, the structure is simple, and manufacturing is easy.
