A surgical instrument is disclosed including a transducer configured to provide vibrations along a longitudinal axis, an end effector operably coupled to the transducer, and a stationary lower jaw extending parallel to the end effector. The end effector extends along the longitudinal axis. The end effector comprises a blade. The stationary lower jaw comprises a clamp face positioned distal to the blade. The end effector is movable relative to the stationary lower jaw to drive the blade distally towards the clamp face. The end effector comprises a hollow lumen. The end effector further comprises at least one member extended across a portion of the hollow lumen.

Surgical instruments

A surgical device is disclosed including a surgical instrument and an outer sheath surrounding the surgical instrument. The surgical instruments includes an end effector including a first jaw member and a second jaw member. At least one of the first jaw member or the second jaw member is pivotable toward the other to grasp tissue. The outer sheath is slidable relative to the surgical instrument along a longitudinal axis between a first position, wherein the first jaw member and the second jaw member are positioned within the outer sheath proximal to a distal portion of the outer sheath, and a second positon, wherein the first iaw member and the second iaw member are positioned outside the outer sheath distal to the distal portion of the outer sheath. The distal portion of the outer sheath is configured to clamp tissue.

A surgical device comprising an end effector is disclosed. The surgical device comprises a trigger actuatable to cause the end effector to be energized and a circuit in communication with the trigger. The circuit is configured to, when a first level of force is applied to the trigger, drive the end effector at a first level, when a second level of force is applied to the trigger, drive the end effector at a second level, and, delay by a first period of time between indicating a change in the force applied to the trigger from the first level of force to the second level of force and a change from driving the end effector at the first level to driving the end effector at the second level, wherein the first period of time is sufficient to give a user a warning about the change in the force.

A surgical device. The surgical device may comprise a transducer configured to provide vibrations along a longitudinal axis and an end effector coupled to the transducer and extending from the transducer along the longitudinal axis. The surgical device also may comprise a lower jaw extending parallel to the end effector. The lower jaw may comprise a clamp face extending toward the longitudinal axis. Also, the lower jaw may be slidable relative to the end effector to bring the clamp face toward a distal end of the end effector.

An ultrasonic surgical system includes an ultrasonic transmission member having a proximal end and a distal end. An ultrasonically actuated end-effector is attached at the distal end of the transmission member. A pressurized fluid delivery system includes a fluid nozzle in communication with at least one fluid source. The fluid nozzle is arranged and configured to deliver pressurized fluid to soft tissue at a rate to move the soft tissue away from the end-effector during use.
