  • ALIGNMENT FEATURES FOR ULTRASONIC SURGICAL INSTRUMENT
    Publication number: 20210236151
    Abstract: 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.

  • Ultrasonic surgical instrument with integral blade cleaning feature
    Patent number: 9901358
    Abstract: 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. The shaft assembly comprises a feature to provide for the removal of surgical debris (e.g. tissue, coagulated blood, etc.), body fluid, etc. from the shaft assembly. The feature may remove the surgical debris, body fluid, etc. from a cavity within the shaft assembly. The feature may also prevent the collection of surgical debris, body fluid, etc. within the shaft assembly.
