摘要： A latch mechanism for a surgical instrument includes a lever moveable from an initial position to an actuated position for moving an end effector assembly from a first to a second state. A pin extends from the lever. A cantilever spring is operably engaged to the housing of the instrument. A pin track member is operably engaged to the cantilever spring at a free end thereof. The pin track member is configured to permit translation of the pin therealong between a first position corresponding to the initial position of the lever and a second position corresponding to the actuated position of the lever. The pin is configured to translate from the first to the second position along a first path and from the second position back to the first position along a second path and is configured to be releasably retained in the second position.

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.

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 spindle assembly of a surgical instrument is provided which includes a body and a cutter pin. The body has at least one wall forming first and second channels therein. The cutter pin is disposed within the second channel and operably coupled to a knife rod extending therethrough and is operatively coupled at its distal end to a knife. When the knife rod is moved between a retracted position and a deployed position, the spindle assembly is moved between a first and a second position along the shaft. The cutter pin is configured to deform and exit the body when the knife is deployed and disposed in a trapped condition and in response to an applied force, thereby decoupling the knife from the spindle assembly.

摘要： A forceps includes an end effector assembly having first and second jaw members disposed in opposed relation relative to one another. One (or both) of the jaw members is moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue therebetween. A knife is longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position. The knife coupled to one or both of the jaw members via a pin-slot engagement such that, upon translation of the knife from the retracted position to the intermediate position, the first and second jaw members are moved to the approximated position to grasp tissue therebetween and such that, upon translation of the knife from the intermediate position to the extended position, the knife is extended between the jaw members to cut tissue grasped therebetween.

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.
