    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 surgical instrument comprises a handle assembly including an actuator mounted for manipulation through an actuation stroke. An elongate shaft extends distally from the handle assembly and defines a longitudinal axis. A reciprocating member extends at least partially through the elongate shaft, and is mounted for longitudinal motion through the elongate shaft in response to manipulation of the actuator through the actuation stroke. A drive mechanism includes a first rotating component coupled to the actuator about a first circumference to induce rotational motion in the first rotating component. A second rotating component is coupled to the first rotating component such that rotational motion in the first rotating component induces rotational motion in the second rotating component. The second rotating component is coupled to the reciprocating member about a second circumference such that rotational motion of the second rotating component induces longitudinal motion in the reciprocating member. The second circumference is greater than the first circumference.

    摘要： A surgical instrument includes a handle and an elongated shaft extending distally from the handle. The elongated shaft includes a proximal portion coupled to the handle and a distal portion pivotally coupled to the proximal portion. An end effector is coupled to the distal portion of the elongated shaft and is articulatable relative to a longitudinal axis defined by the instrument. A cam member is rotatably mounted about the longitudinal axis and configured to impart a force to the distal portion of the elongated shaft upon rotation of the cam member to effect pivotal motion of the distal portion of the elongated shaft, and thus articulation of the end effector. An articulation actuator is supported on the handle and is operable to impart rotational motion to the cam member.
