摘要： An endoscopic forceps includes a housing having a shaft extending therefrom for treating tissue. A longitudinal axis is defined through the shaft. An end effector assembly is operably coupled to a distal end of the shaft and includes a pair of first and second jaw members. A rotating assembly operably coupled to the shaft is configured to rotate the shaft and the end effector about the longitudinal axis. A drive assembly is configured to selectively and releasably engage the rotating assembly. Engagement of the rotating assembly with the drive assembly couples the rotating assembly to the shaft such that the shaft is rotatable about the longitudinal axis in a predetermined direction when the rotating assembly is rotated. And, disengagement of the rotating assembly from the drive assembly uncouples the rotating assembly from the shaft such that the shaft is non-rotatable about the longitudinal axis when the rotating assembly is rotated.

摘要： A forceps includes an end effector assembly including first and second jaw members, a blade, a lever member operably coupled to the end effector, a trigger member operably coupled to the blade and defining an actuation path therealong. A trigger safety member is pivotably coupled to the lever member such that, when the lever member is disposed in an initial position, the trigger safety member is disposed in a position blocking the trigger member. When the lever member is disposed in a compressed position, the trigger safety member is disposed in a position, wherein the trigger safety member is displaced from the actuation path to permit movement of the trigger member, wherein the safety member rotates relative to the lever member as a function of movement of the lever member to block/unblock the trigger member.

摘要： A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes an elongated proximal segment and a distal segment. The distal segments are configured to grasp tissue therebetween. The jaw members are biased towards a spaced-apart position relative to one another. A sliding unit is disposed about the first and second jaw members and is slidable relative to the jaw members between a first position, wherein the sliding unit is disposed about the elongated proximal segments of the jaw members, and a second position, wherein the sliding unit is disposed about the distal segments of the jaw members. The sliding unit is configured to transition the jaw members against the bias from the spaced-apart position to an approximated position for grasping tissue therebetween upon sliding of the sliding unit from the first position to the second position.

A drive bar is coupled to the end effector and extends into the housing. The drive bar is translatable between first and second positions for transitioning the end effector between the first and second conditions. A handle assembly is moveable between initial and actuateds position for translating the drive bar between the first and second positions. One or more linkages couple the drive bar, the handle assembly, and the housing to one another by at least first, second and third pivots. At least one of the pivots is fixed and at least one of the pivots is floating. The second pivot is movable relative to the first and third pivots between an unlatched position and an over-center latched position for latching the end effector in the second condition.

摘要： An electrosurgical instrument for treating tissue includes a housing having a shaft extending therefrom having an axis A-A defined therethrough. The shaft is at least partially flexible and includes first and second jaw members attached at a distal end thereof. Each jaw member includes an electrically conductive tissue contacting surface adapted to connect to a source of electrosurgical energy such that the electrically conductive tissue contacting surfaces are capable of conducting electrosurgical energy through tissue held therebetween. A drive assembly is disposed in the housing and has a first actuator operably coupled to a drive rod for reciprocation thereof to move the jaw members from a first position in spaced relation to one another to a second position closer to one another for engaging tissue. A second actuator is disposed on the housing and is actuatable to articulate the shaft
