In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument. | 03-05-2015 |
20150080876 | INTEGRATED SYSTEMS FOR ELECTROSURGICAL STEAM OR SMOKE CONTROL - A medical device includes an end effector and a fluid control system configured to control fluid generated when the end effector applies energy to target tissue and includes a fluid path element having one or more fluid paths. The one or more fluid paths include a distal fluid port positioned adjacent to a working portion of the end effector and a proximal fluid port fluidically coupled to a supply and transport element. The supply and transport element is configured to one of evacuate and supply fluid adjacent to the working portion of the end effector. The supply element may be operatively coupled to an activation element configured to activate the supply and transport element when end effector applies energy to the target tissue. | 03-19-2015 |
20150080879 | INTEGRATED SYSTEMS FOR ELECTROSURGICAL STEAM OR SMOKE CONTROL - A medical device includes an end effector configured to apply bipolar energy to target tissue along a working portion thereof and a fluid control system to control the flow of a fluid produced when the end effector applies the bipolar energy to heat the target tissue. The fluid control system includes a fluid path element defining a fluid path, a distal fluid port configured to intake the fluid adjacent to the working portion of an end effector for transport through the fluid path, and a proximal fluid port configured to intake the fluid transported through the fluid path and to exhaust the transported fluid. | 03-19-2015 |
20150080924 | ARTICULATION FEATURES FOR ULTRASONIC SURGICAL INSTRUMENT - A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section includes a collar that is located distal to a nodal portion of the waveguide and is operable to deflect the end effector away from the longitudinal axis. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation drive assembly is operable to drive articulation of the articulation section. The articulation drive assembly comprises at least one translating articulation driver coupled with the collar. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue even when the articulation section is in an articulated state. | 03-19-2015 |
20150080925 | ALIGNMENT FEATURES FOR ULTRASONIC SURGICAL INSTRUMENT - An ultrasonic instrument comprises a body, a shaft assembly, an ultrasonic blade, and a pivoting member. The shaft assembly extends distally from the body. The ultrasonic blade is positioned distal to the shaft assembly. The pivoting member is pivotable with respect to the blade from an open position to a closed position to thereby clamp tissue between the pivoting member and the blade. One or both of the shaft assembly or the pivoting member comprise a guide feature. The guide feature is configured to provide lateral alignment of the distal portion of the pivoting member with the blade as the pivoting member is pivoted to the closed position. | 03-19-2015 |
