    • Various embodiments are directed to an apparatus, system, and method for driving an end effector coupled to an ultrasonic transducer in a surgical instrument. The method comprises generating a first ultrasonic drive signal by a generator coupled to an ultrasonic drive system, actuating the ultrasonic transducer with the first ultrasonic drive signal for a first period, generating a second ultrasonic drive signal by the generator, and actuating the ultrasonic transducer with the second ultrasonic drive signal for a second period, subsequent to the first period. The first drive signal is different from the second drive signal over the respective first and second periods. The first and second drive signals define a step function waveform over the first and second periods. The apparatus comprises a generator configured to couple to an ultrasonic instrument. The system comprises a generator coupled to an ultrasonic instrument. The ultrasonic instrument comprises an ultrasonic drive system comprising an ultrasonic transducer coupled to a waveguide and an end effector coupled to the waveguide, and wherein the ultrasonic drive system is configured to resonate at a resonant frequency.

    • Disclosed is an ultrasonic surgical instrument that combines end-effector geometry to best affect the multiple functions of a shears-type configuration. The shape of the blade is characterized by a radiused cut offset by some distance to form a curved geometry. The cut creates a curved surface with multiple asymmetries causing multiple imbalances within the blade. Imbalance due to the curve of the instrument is corrected by a non-functional asymmetry proximal to the functional asymmetry. Imbalance due to the asymmetric cross-section of the blade is corrected by the appropriate selection of the volume and location of material removed from a functional asymmetry. The shape of the blade in one embodiment of the present invention is characterized by two radiused cuts offset by some distance to form a curved and potentially tapered geometry. These two cuts create curved surfaces including a concave surface and a convex surface. The length of the radiused cuts affects, in part, the acoustic balancing of the transverse motion induced by the curved shape.
    • 公开了一种超声手术器械,其结合了末端执行器几何形状以最好地影响剪切型构型的多种功能。 叶片的形状的特征在于圆角切割偏移一定距离以形成弯曲的几何形状。 切割产生具有多个不对称性的弯曲表面,导致叶片内的多个不平衡。 由于仪器曲线的不平衡是通过功能不对称的非功能不对称来校正的。 通过适当选择从功能不对称中去除的材料的体积和位置来校正由于叶片的不对称横截面引起的不平衡。 在本发明的一个实施例中,叶片的形状的特征在于两个圆角的切口偏移一定距离以形成弯曲和潜在的锥形几何形状。 这两个切口产生包括凹面和凸面的曲面。 圆弧切割的长度部分地影响由弯曲形状引起的横向运动的声学平衡。
