    摘要： Systems and methods heat or ablate body tissue by positioning an electrode to transmit heat or ablation energy to a tissue region. The systems and methods measure a first temperature using a temperature sensing element associated with the electrode. The systems and methods also measure a second temperature using a temperature sensing element associated with the electrode. The systems and methods process at least one of the first and second temperatures to derive a prediction of maximum temperature of the tissue region. The systems and methods generate an output that controls the transmission of the heating or ablation energy based, at least in part, upon the maximum tissue temperature prediction.

    摘要： Systems and methods using an electrode able to transmit heating or ablation energy into tissue include first and second sensing elements associated with the electrode for measuring first and second temperatures. The electrode also includes a heating element in thermal conductive contact with the electrode for heating the electrode. The systems and methods sequentially activate the heating element and sense temperatures without transmitting tissue heating or ablation energy, and then transmit heating or ablation energy and sense temperatures without activating the heating element, to derive from the sensed temperatures a prediction of maximum tissue temperature.

    摘要： An electrosurgical system includes an end effector assembly including first and second jaw members each defining an electrically-conductive tissue-contacting surface. At least one of the jaw members is movable between spaced-apart and approximated positions for grasping tissue between the tissue-contacting surfaces. At least one temperature sensor is associated with the end effector assembly. An electrosurgical generator is configured to supply electrosurgical energy for treating tissue grasped between the tissue-contacting surfaces. The generator is configured to receive sensed data indicative of temperature from the temperature sensor and includes a controller configured, in real time, to control the supply of energy to tissue, predict thermal spread beyond the first and second jaw members based at least on the sensed temperature data, and modify, where it is determined that the predicted thermal spread is above a threshold thermal spread, the supply of energy to tissue to inhibit realization of the predicted thermal spread.
