摘要： An electrosurgical forceps is provided. The electrosurgical forceps includes a housing having a shaft extending distally therefrom. The shaft defines a longitudinal axis therethrough and a knife blade shaft is operably disposed within the shaft. An end effector is operably disposed at a distal end of the shaft. The end effector includes a pair of spaced-apart first and second jaw members that are movable from an open configuration to a clamping configuration. An electrode assembly includes first and second electrode housings and a knife blade. The first and second electrode housings are operably coupled to one another and are configured to selectively couple to respective first and second jaw members to electrosurgically treat tissue clamped between the first and second jaw members. The knife blade is configured to selectively couple to the knife blade shaft.

摘要： An endoscopic surgical instrument is provided. The instrument includes a housing, a handle, an elongated shaft extending distally from the housing and defining a longitudinal axis, an end effector assembly (120), a drive assembly, a clevis (150), a first link (160), and a second link (170). The end effector assembly is disposed adjacent a distal end of the elongated shaft and includes a first jaw member (130) and a second jaw member (140). The first link (160) is pivotably connected to the clevis (150) about a first pivot axis (152), and is pivotably connected to the first jaw member about a first jaw member pivot. The second link (170) is pivotably connected to the clevis (150) about a second pivot axis (154), and is pivotably connected to the second jaw member about a second jaw member pivot. The first pivot axis (152) and the second pivot axis (154) are offset from the longitudinal axis.
