  • Ultrasonic surgical instrument with removable shaft assembly portion
    Patent number: 10327797
    Abstract: An apparatus includes a body, a shaft assembly, and an end effector. The shaft assembly includes an outer tube, a proximal inner tube member, a distal inner tube member, and an acoustic waveguide. The end effector includes an ultrasonic blade and a clamp arm. A first portion of the clamp arm is pivotably coupled with a distal end of the outer tube. A second portion of the clamp arm is pivotably coupled with a distal end of the distal inner tube member. The outer tube is configured to removably couple with the body and the distal inner tube member is configured to removably couple with the proximal inner tube member such that the outer tube, the distal inner tube member, and the clamp arm are configured to removably couple with the body and the remainder of the shaft assembly and end effector as a unit.

  • SURGICAL INSTRUMENT WITH REMOVABLE END EFFECTOR COMPONENTS
    Publication number: 20180132887
    Abstract: A surgical instrument includes an ultrasonic waveguide extending through a body assembly. An ultrasonic blade connects to the ultrasonic waveguide. A clamp arm assembly of the surgical instrument is able to move from an opened position for receiving a tissue toward a closed position for clamping the tissue. The clamp arm assembly includes a clamp body and a clamp pad facing the ultrasonic blade. A clamp arm actuator of the surgical instrument is able to move from a first position toward a second position to direct the clamp arm assembly from the opened position toward the closed position. A modular coupling of the surgical instrument connects to the clamp pad such that at least the clamp pad can be disconnected relative to the ultrasonic blade for replacement thereof.

  • END EFFECTOR FOR INSTRUMENT WITH ULTRASONIC BLADE AND BIPOLAR CLAMP ARM
    Publication number: 20170164973
    Abstract: An apparatus includes a body, a shaft assembly, and an end effector. The end effector includes an ultrasonic blade and a clamp arm assembly. The ultrasonic blade is in acoustic communication with an acoustic waveguide of the shaft assembly. The clamp arm assembly is pivotable toward and away from the ultrasonic blade. The clamp arm assembly includes a first electrode and a second electrode. The first and second electrodes are operable to cooperate to apply bipolar RF energy to tissue.

  • METHOD OF TREATING TISSUE USING END EFFECTOR WITH ULTRASONIC AND ELECTROSURGICAL FEATURES
    Publication number: 20170164997
    Abstract: An end effector of an instrument is positioned in a patient. An ultrasonic blade of the end effector is positioned against tissue in the patient. The ultrasonic blade is activated to vibrate ultrasonically while the ultrasonic blade is positioned against tissue. At least one electrode of the end effector is positioned against tissue in the patient. The at least one electrode is activated to apply RF electrosurgical energy to tissue against which the at least one electrode is positioned against tissue.
