    Abstract: An ultrasonic surgical instrument including a blade that treats tissue and a fluid control system to cool the blade by pumping cooling fluid through the blade. The blade defines a blade lumen in fluid contact with an inflow and return conduit of the fluid control system. The fluid control system may further include a fluid reservoir holding the cooling fluid and a pump. The pump is configured to deliver the fluid from the fluid reservoir, through the inflow conduit and the blade lumen, and into return conduit.

    Abstract: An ultrasonic surgical instrument is provided, including a handpiece, a lever operably coupled to the handpiece and movable between first, second, and third positions, a shaft assembly extending distally from the handpiece, and an ultrasonic waveguide extending through the shaft assembly and defining a fixed jaw member at a distal end portion thereof. An outlet at the distal end of the fixed jaw member provides irrigation of fluid. The waveguide functions as an aspirator well as a transector/dissector of tissue. A movable jaw member is disposed towards a distal end portion of the shaft assembly and is operably coupled to the lever such that movement of the lever between the first, second, and third positions moves the movable jaw member relative to the fixed jaw member between a retracted position, an extended open position, and an extended closed position.

    Abstract: An endoscopic instrument is provided and includes a housing including an elongated shaft assembly extending distally therefrom. The elongated shaft assembly includes inner and outer shaft members. The inner and outer shaft members are removably coupled to the housing and the outer shaft member is movable with respect to the inner shaft member. An end effector is operably supported at the distal end of the outer shaft member and includes a pair of jaw members configured for treating tissue. A bushing operably couples to the inner and outer shaft members of the shaft assembly and selectively and releasably couples to the housing. The bushing includes one or more mechanical interfaces configured to engage one or more slots defined through the inner shaft member and one or more slots defined through the outer shaft member to release the inner and outer shaft members from the housing.

    Abstract: A surgical instrument includes an end effector assembly having jaw members movable between spaced-apart, first approximated, and second approximated positions. A knife is selectively movable relative to the end effector assembly between a retracted position, a first extended position, and a second extended position. A trigger is selectively actuatable between a un-actuated position, a first actuated position, and a second actuated position for moving the knife between its respective positions. A control member prevents movement of the trigger when the jaw members are disposed in the spaced-apart position, permits movement of the trigger to the first actuated position but prevents movement beyond the first actuated position when the jaw members are disposed in the first approximated position, and permits movement of the trigger to the second actuated position but prevents movement beyond the second actuated position when the jaw members are disposed in the second approximated position.
