摘要： An electrosurgical instrument includes a housing and a first connector in the housing for receiving electrical energy. A shaft assembly is movably connected to the housing. The shaft assembly also includes at least one electrode at a distal end of the shaft assembly as well as at least one conductive portion for passing the electrical energy to the electrode. A spring is positioned between the shaft assembly and the housing for biasing the shaft assembly a distance away from the first connector. The distance defines a pre-determined gap between the first connector and the shaft assembly. The shaft assembly is proximally movable in the housing upon an application of force at the shaft assembly distal end for compressing the spring such that the conductive portion traverses the predetermined gap such that electrical energy is passed from the first connector to the electrode through the conductive portion.

摘要： An electrosurgical stapling instrument includes an end effector capable of applying bipolar RF energy into tissue. The end effector has a first pole electrode and a second pole electrode for forming an RF contact circuit with tissue. At least one of the electrodes may have a dielectric coating thereon to create a RF circuit with tissue. The dielectric coating can cover one of the electrodes to create a capacitive coupling circuit with tissue, or can have at least one open passageway extending through the dielectric coating to enable tissue contact with the electrode and the passage of RF energy therethrough. The dielectric coating on the electrode can be masked to create passageways through the dielectric, or the dielectric coating can be locally removed with a variety of techniques to form passageways. The dielectric coating may provide a barrier to prevent shorting between the dielectrically coated electrode and a conductive fastener embedded within tissue. Alternately, a cartridge coating can be used to reduce an electric surface sheet charge on the cartridge thermoplastic that can occur during the application of RF energy to tissue.
