    Abstract: A forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. A knife assembly having a cutting blade disposed at a distal end thereof is also provided. The knife assembly is translatable relative to the end effector assembly between a retracted position and an extended position, wherein the cutting blade extends between the jaw members to cut tissue grasped therebetween. The knife assembly includes a proximal component and a first distal component that includes the cutting blade. The proximal and first distal components are removably coupled to one another to facilitate replacement of the first distal component. Methods of preparing such forceps for reuse are also provided.

    Abstract: A surgical instrument includes a pair of jaw members moveable between a spaced-apart and an approximated position. A drive bar is translatable between a distal and a proximal position for moving the jaw members between the spaced-apart and approximated positions. A lever is moveable between an initial position and an actuated position for translating the drive bar between the distal and proximal positions. A sleeve disposed about the drive bar includes an annular track having a substantially radial segment(s) and a substantially longitudinal segment(s). A collar interdisposed between the sleeve and the drive bar includes a stop member(s) extending radially outwardly therefrom. The stop member(s) is engaged within the track and is translatable from a first position, wherein the stop member is positioned within the longitudinal segment, to a second position, wherein the stop member is engaged within the radial segment, to lock the lever in the actuated position.

    Abstract: An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.

    Abstract: A surgical instrument for providing an ionized gas to a surgical site includes a receptacle for at least one cylinder of pressurized surgical gas and a frame having a port near the distal end for emitting the surgical gas. A passageway extending between the receptacle and the port delivers the surgical gas to the port. A puncture assembly for rupturing a seal on at least one cylinder to release the surgical gas into the passageway includes at least one bank for storing mechanical energy which may include at least one spring. An actuator is operable to actuate the at least one bank release the mechanical energy. At least one puncture pin is operatively coupled to the at least one bank such that energy released by the at least one bank is effective to move the at least one puncture pin relative to at least one cylinder to rupture the seal.
