摘要： An electrosurgical generator is disclosed. The generator includes an RF output stage configured to supply electrosurgical energy to tissue via at least one active electrode configured to apply electrosurgical energy to tissue; sensing circuitry configured to measure impedance of tissue; and a controller. The controller is configured to determine occurrence of a tissue reaction 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; generate a target impedance trajectory as a function of measured impedance and desired rate of change based on the tissue reaction determination, wherein the target impedance trajectory includes a plurality of target impedance values; and drive tissue impedance along the target impedance trajectory by adjusting the output of the electrosurgical generator to substantially match tissue impedance to a corresponding target impedance for at least a predetermined minimum time period.

摘要： A forceps includes an end effector assembly including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced apart position, a first approximated position, and a second approximated position. The jaw members are configured to apply a pre-determined pressure to tissue disposed therebetween in each of the first and second approximated positions. A sealing pressure is applied to tissue disposed between the jaw members when the jaw members are in the first approximated position. A cutting pressure is applied to tissue disposed between the jaw members when the jaw members are in the second approximated position.

摘要： A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft.

摘要： An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly includes a pair of first and second jaw members pivotably coupled to one another via a pivot pin. One or both of the first and second jaw members may be movable from an open position for positioning tissue therebetween to a clamping position for grasping tissue. A detent is operably disposed proximal the pivot pin and extends radially outward from a proximal flange of one of the jaw members. The detent is configured to releasably engage a corresponding slot disposed on a proximal flange of the other jaw member. The detent and slot are configured to control a gap distance between the first and second jaw members when the first and second jaw members are in the clamping position.

摘要： A forceps includes an end effector assembly. The end effector assembly includes first and second jaw members. At least one of the jaws is moveable with respect to the other between a spaced-apart position and at least one approximated position for grasping tissue therebetween. At least one of the jaw members is adapted to connect to a source of energy for sealing tissue disposed between the jaw members. A chamber is defined within and extends longitudinally along at least one of the jaw members. The chamber is configured to retain a fluid therein and includes a series of apertures disposed on a tissue-facing surface thereof such that, upon application of energy to the jaw member(s), fluid within the chamber is heated to thermally expand within the chamber and forcefully exit the apertures to divide tissue disposed between the jaw members.
