摘要： An electrosurgical instrument may comprise electrodes provided on the working surfaces of each jaw member that can be set to different electrical potentials and/or polarities to perform electrosurgical operations, such as sealing and cutting. Different combinations of electrodes can be selectively activated to create different pathways for the transfer of electrical energy through the material, to achieve the desired effects.

摘要： A method is provided to seal and cut biological tissue. An alternating current (AC) scaling signal is imparted between a set of sealing electrodes. An AC cutting signal is imparted between a set of cutting electrodes in response to a biological tissue impedance between the sealing electrodes reaching a first impedance threshold value. The AC scaling signal is halted at an end of a time interval, beginning while the AC cutting signal is imparted between the cutting electrodes, in response to impedance of the biological tissue disposed between the set of sealing electrodes reaching a second impedance threshold value.

摘要： A method is provided to control delivery of heat to biological tissue comprising: imparting an RF electrical signal to the biological tissue electrically coupled between a first electrode and the second electrode; measuring frequency content of the RF electrical signal between the first electrode and the second electrode; and adjusting the RF electrical signal based upon the measured frequency content of the RF electrical signal.

摘要： Abstract: An electrosurgical method is provided to seal biological tissue comprising providing RF power to the tissue during an RF power delivery time interval comprising: measuring a change in impedance of the tissue with respect to RF energy delivered to the tissue during an initial portion of the time interval; selecting an RF power delivery profile, based at least in part upon the measured change in impedance of the tissue with respect to RF energy delivered to the tissue; and imparting RF power to the tissue according to the selected RF power delivery profile during a latter portion of the time interval.
