    摘要： An endoscopic bipolar forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The shaft includes jaw members adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. The forceps include a drive assembly that moves the jaw members relative to one another from a first position to a second position for manipulating tissue. A movable handle is included that is rotatable about a pivot. A knife assembly is also included having a movable knife rod to operatively engage a knife blade, the knife rod having a first longitudinal section having a first predetermined shape, and a second longitudinal section having a second predetermined shape. The first predetermined shape is different than the second predetermined shape.

    摘要： An electrosurgical forceps includes a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly is operably coupled to a distal end of the shaft and includes a pair of first and second jaw members. Each jaw member has a jaw housing and an electrosurgical seal plate. The first jaw member is movable relative to the second jaw member from an open configuration to a clamping configuration. The first jaw member includes an elongated channel defined in its respective jaw housing and extends along a length thereof. A drive assembly operably couples to the first jaw member via a drive rod that is engageable with the elongated channel to move the first jaw member from the open configuration to the clamping configuration and to provide a closure force between the jaw members when the jaw members are in the clamping configuration.

    摘要： A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes a bifurcated proximal flange extending therefrom defining first and second spaced-apart flange components. The first flange components are pivotably engaged to one another via a first engagement portion and the second flange components are pivotably engaged to one another via a second engagement portion. One or both of the jaw members is pivotable relative to the other about the first and second engagement portions between an open position and a closed position for grasping tissue therebetween. A guide member is configured for positioning between the proximal flanges of the jaw members. The guide member includes a tab extending transversely therefrom that is configured to operably engaged one of the first and second engagement portions to retain the jaw members in engagement with one another.

    摘要： An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade.
