SYSTEM AND METHOD FOR TISSUE SEALING

摘要

An electrosurgical system is disclosed. The electrosurgical system includes an
electrosurgical generator adapted to supply electrosurgical energy to tissue.
The
electrosurgical generator includes impedance sensing circuitry which measures
impedance of
tissue, a processor configured to determine whether a tissue reaction has
occurred as a
function of a minimum impedance value and a predetermined rise in impedance,
wherein
tissue reaction corresponds to a boiling point of tissue fluid, and an
electrosurgical instrument
including at least one active electrode adapted to apply electrosurgical
energy to tissue. A
tissue cooling period is provided to enhance operative outcomes.
