    摘要： A surgical instrument is provided. The surgical instrument includes a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members. The surgical instrument includes a handle assembly that includes a movable handle movable relative to a fixed handle operable to impart movement of the jaw members relative to one another. A rotating assembly is configured for rotating one of the shaft and end effector assembly about the longitudinal axis. The rotating assembly is supported in the housing and includes first and second drive. Each of the first and second drive wheels are selectively movable relative to the housing and configured such that rotation of the first drive wheel causes rotation of the second drive wheel and the shaft.

    摘要： An endoscopic forceps includes a housing having a shaft attached thereto that supports a pair of jaws disposed at a distal end thereof. A drive assembly having a drive shaft with a proximal end is operable to move the jaws relative to one another from an open to closed positions. A knife assembly is operable to advance a knife through tissue disposed between the jaws and includes a flange disposed thereon. A knife lockout is included that has a flange configured to engage the proximal end of the drive shaft and a lockout arm configured to engage the flange of the knife assembly to prevent movement thereof. Movement of the jaws to the closed position causes the proximal end of the drive shaft to engage the flange on the lockout which causes the lockout arm to disengage the flange on the knife assembly to permit advancement of the knife.

    摘要： A forceps includes a housing having a shaft extending therefrom. The shaft has an end effector assembly that defines a longitudinal axis therethrough. The end effector assembly includes first and second jaw members disposed in opposed relation and moveable from a first, open position to a second, closed position for grasping tissue therebetween and a knife. One or more jaw members include knife blade channels defined therein. Each knife blade channel includes a polygonal longitudinal cross-section defined therein. The knife includes a knife edge and a knife base. The knife base includes a corresponding polygonal longitudinal cross-section. The knife is configured to translate through the knife blade channels and the knife base is configured to slidingly engage the knife base channel having the polygonal cross section upon translation of the knife. In embodiments, the knife blade channel and the knife base have a T-shaped longitudinal cross-section.
