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 instrument comprising a transducer configured to produce vibrations along a longitudinal axis. The surgical instrument further comprises an ultrasonic blade extending along the longitudinal axis. The ultrasonic blade is coupled to the transducer and comprises a body and a treatment region. The body comprises a proximal end, a distal end, and a bottom surface. The distal end of the body is movable relative to the longitudinal axis by the vibrations produced by the transducer. The treatment region extends from the proximal end to the distal end. The surgical instrument further comprises a protective sheath disposed adjacent to the bottom surface of the ultrasonic blade.

Ultrasonic surgical instruments

A surgical instrument is disclosed comprising a housing, a transducer supported within the housing, an end-effector engaged with the transducer, and a clamp including a jaw member movably supported relative to the end-effector between an open position and a closed position. The transducer is configured to produce vibrations. The end-effector defines an axis and a distal tip. The distal tip is movable relative to the axis by vibrations produced by the transducer. The end-effector is configured to be detached from the transducer. The transducer is configured to receive a different end-effector.

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 instrument configured to be coupled to a transducer configured to produce vibrations. The surgical instrument comprises an end effector comprising an ultrasonic blade, a protective sheath, and outer tube and an aperture. The ultrasonic blade extends along a longitudinal axis of the end effector and is configured to be coupled to a transducer. The protective sheath extends at least partially around the ultrasonic blade. The outer tube extends at least partially along the longitudinal axis. The aperture defines a channel extending at least partially through the end effector along the longitudinal axis.

A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can further include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can be set such that the sheath can act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath in order to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.

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.

A surgical instrument includes a transducer configured to produce vibrations at a predetermined frequency. The transducer is configured to produce vibrations along a longitudinal axis at a predetermined frequency. An ultrasonic blade extends along the longitudinal axis and is coupled to the transducer. The ultrasonic blade includes a body having a proximal end and a distal end. The distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer. The body includes a treatment region that extends from the proximal end to the distal end. The body includes a substantially flat broad top surface, a bottom surface, and a neck portion protruding from the proximal end adapted to couple to the transducer.

A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can enable the sheath to act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.
