摘要： An end effector assembly for use with an instrument for sealing vessels and cutting vessels includes a pair of opposing first and second jaw members which are movable relative to one another from a first spaced apart position to a second position for grasping tissue therebetween. Each jaw member includes a pair of spaced apart electrically conductive tissue contacting surfaces which each have an insulator disposed therebetween, the conductive surfaces are connected to an electrosurgical energy source. The first jaw member includes an electrically conductive cutting element disposed within the insulator which extends towards the second tissue contacting surface to create a gap therebetween. The cutting element is inactive during the sealing process while the two pairs of electrically conductive surfaces are activated to seal tissue. During the cutting process, the cutting element is energized to a first potential and at least one electrically conductive tissue contacting surface is energized to a different potential to effect a tissue cut through the tissue held between the jaw members along the already formed tissue seal.

摘要： System and method for controlling delivery of energy to divide tissue are disclosed. The system comprises an electrosurgical instrument having an electrically energizable cutting element which communicates electrical energy to the tissue and a generator to supply the energy to the electrosurgical instrument which supplies the energy to the tissue in a first pulse to react the tissue, in slow pulses to create a desiccation line until impedance at the tissue has reached a threshold, and in rapid pulses to divide tissue across the desiccation line.
