    摘要: An end effector for use with an ultrasonic surgical instrument. A body extends along a longitudinal axis. The body includes a proximal end and a distal end. The proximal end of the body is configured to couple to an ultrasonic transducer configured to produce vibrations at a predetermined frequency. A folded element includes a first end coupled to the distal end of the body at a predetermined region between a node and an antinode. The folded element extends along the longitudinal axis from the distal end to the proximal end of the body. The folded element comprises a second free acoustic end. A distal portion of the body and the folded element define a parallel acoustic path.

    摘要: An end effector includes a first portion having a first specific acoustic impedance value, and a second portion having a second specific acoustic impedance value less than the first specific acoustic impedance value. The first portion includes a proximal end segment of the end effector and a distal end segment of the end effector, and the proximal end segment and the distal end segment are composed of a first material. The second portion includes an insert segment of the end effector composed of a second material. The insert segment is located between the proximal end segment and the distal end segment along the longitudinal axis of the end effector. The insert segment functions to bridge or fill the nodal energy gap. A surgical instrument includes a transducer configured to produce vibrations along a longitudinal axis as a predetermined frequency. An ultrasonic blade extends along the longitudinal axis coupled to the transducer. An insert segment or a pad is positioned adjacent to the blade such that it engages the blade when the surgical instrument is in a closed position and generates heat filling the nodal energy gap.

    摘要: 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.

    摘要: A method for detecting loose blades in a hand piece connected to an ultrasonic surgical system by performing frequency sweeps of a drive signal through a range which includes the resonance of a hand piece/blade system and the resonance of the hand piece without a blade attached. The frequencies of resonance in each sweep are compared. If a substantial difference between the frequency sweeps occurs, then a “Tighten Blade” message is displayed on a liquid crystal display on an ultrasonic generator console. The method permits rapid and easy diagnosis of loose blade connections. The method also assists a surgeon or nurse in knowing when to tighten the blade, as opposed to performing more lengthy and detailed diagnostic or cleaning procedures. In addition, the time and costs associated with the diagnostic procedures to isolate faults are eliminated because, upon determining that the blade is not loose, the surgeon and/or nurse can request a new blade based on the assumption that the blade is broken.

    摘要: A robotically controlled surgical tool including a lockout mechanism is provided. The surgical tool may comprise an instrument mounting portion. The instrument mounting portion includes a housing, a plate, a shaft assembly comprising an end effector, and a coupler to couple the shaft assembly to the instrument mounting portion. The end effector comprises a first jaw member and a second jaw member, the first and second jaw members defining a channel therebetween, and a blade slideably receivable within the channel to cut tissue located between the first and second jaw members. The surgical tool may include an actuation mechanism to actuate the end effector to provide reciprocating movement of the blade within the channel. A lockout mechanism is coupled to the actuation mechanism. The lockout mechanism may selectively enable reciprocating movement of the blade. An interface mechanically and electrically couples the instrument mounting portion to a robotic manipulator.

The end effector can comprise a first jaw, a second jaw, wherein the first jaw is movable relative to the second jaw in order to capture tissue intermediate the first jaw and the second jaw, a first electrode electrically coupled with the first conductor, and a second electrode electrically coupled with the second conductor, wherein the second electrode is comprised of a material configured to have a first electrical resistance when a first pressure is applied to the material, and wherein the material is configured to have a second electrical resistance when a second pressure is applied to the material. In various circumstances, the material can be configured such that, once the applied pressure has exceeded a switching pressure, the resistance of the material can switch from the first resistance to the second resistance.
