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.

The present application provides a connecting and releasing structure for a balloon system, a balloon system comprising the connecting and releasing structure, and a method for fabricating the same. The connecting and releasing structure is used for connection and release of a catheter and a balloon. The connecting and releasing structure comprises a self-sealing valve positioned on the balloon. The self-sealing valve comprises a catheter connecting port. The catheter passes through the catheter connecting port and is sealedly connected to the self-sealing valve. The self-sealing valve is completely or partially bonded to the inner wall of the balloon. When the catheter is removed after delivery of a filler, the self-sealing valve is not pulled out of the balloon, and thus leakage of the filler can be prevented. In addition, the perimeter of a small orifice in a side wall of the self-sealing valve or the perimeter of the cross-section of the distal end thereof is not greater than the outer diameter of the catheter, and therefore, no leakage occurs when the balloon is full of filler. In addition, the perimeters of cross-sections of the self-sealing valve may differ and increase gradually or stepwise from distal to proximal, thus facilitating the insertion and removal of the catheter.
