    摘要： An apparatus includes an interface assembly and a shaft assembly. The interface assembly is configured for use with a robotic system and includes a first drive assembly and a mounting plate. The mounting plate includes an opening. The first drive assembly is positioned within the opening such that the first drive assembly is laterally translatable within the opening from a first position to a second position. The shaft assembly is removably coupled with the interface assembly. The shaft assembly includes an end effector and a first coupling feature. The first drive assembly of the interface assembly actuates the end effector of the shaft assembly. The first coupling feature is longitudinally aligned with the first drive assembly. The first drive assembly engages the first coupling feature of the shaft assembly when the first drive assembly is laterally translated from the first position to the second position.

    摘要： An electrical ablation apparatus including first, second, and third electrodes is disclosed. Each of the first and second electrode is configured to be selectively extended outside and selectively retracted inside a distal end of its respective lumen and is configured to diverge from its respective longitudinal axis when extended outside the distal end of its respective lumen. The third electrode is non-rotatable and is configured to be selectively extended outside and selectively retracted inside a distal end of its respective lumen. The first, second and third electrodes are extendable into a tissue treatment region to create a first necrotic zone having a first shape. At least one of the first electrode or the second electrode is selectively rotatable within its respective lumen to create a second necrotic zone having a second shape. The third electrode is configured to positionally secure the electrical ablation apparatus at the tissue treatment region.

    摘要： An electrical ablation apparatus comprises first and second electrodes. Each electrode comprises a first end configured to couple an energy source and a second end configured to couple to a tissue treatment region. An energy source is coupled to the first and second electrodes. The energy source is configured to deliver a first series of electrical pulses sufficient to induce cell necrosis by irreversible electroporation and a second series of electrical pulses sufficient to induce cell necrosis by thermal heating, through at least one of the first and second electrodes. The first series of electrical pulses is characterized by a first amplitude, a first pulse length, and a first frequency. The second series of electrical pulses is characterized by a second amplitude, a second pulse length, and a second frequency.

    摘要： An adaptor apparatus comprises a seal assembly housing, a channel, and tapered surfaces. The adaptor apparatus is configured to connect a trocar seal assembly with a robotic trocar cannula and maintain pneumostasis in an insufflated body cavity of a patient. The seal assembly housing comprises an open area sufficient to receive, support, and fix the trocar seal assembly within the adaptor apparatus. The channel provides a pathway for inserting instruments from the trocar seal assembly and into the cannula. The robotic trocar cannula includes an annular flange and a tapered proximal opening. The tapered surfaces of the adaptor apparatus are configured to engage the annular flange and the tapered proximal opening of the cannula. The tapered surfaces of the adaptor apparatus are configured to complement the exterior of the annular flange and the angled opening of the cannula.

    摘要： A surgical instrument is provided that can comprise and end effector including two jaws and a cutting member configured to move between the jaws. In at least one embodiment, one or both of the jaws may be flexible, such that a jaw is configured to flex when gripping tissue. Further, at least one of the jaws may include a thin cross-sectional area such that the jaw flexes when gripping tissue. Additionally, in at least one embodiment, one or more compression elements may extend from the cutting member and may be configured to cause the jaws to close when the cutting member is advanced. The compression elements may comprise a roller and/or a low-friction material. Moreover, in at least one embodiment, one or both of the jaws may be precurved, away from the cutting member's longitudinal axis. Accordingly, in various embodiments, the overall force required to advance the cutting member and/or close the jaws may be reduced.

    摘要翻译： 提供了一种手术器械，其可以包括和末端执行器，包括两个钳口和被配置成在钳口之间移动的切割构件。 在至少一个实施例中，夹爪中的一个或两个可以是柔性的，使得钳夹构造成在夹持组织时弯曲。 此外，夹爪中的至少一个可以包括薄的横截面面积，使得当夹持组织时夹爪弯曲。 另外，在至少一个实施例中，一个或多个压缩元件可以从切割构件延伸，并且可以构造成当切割构件前进时使夹爪关闭。 压缩元件可以包括辊和/或低摩擦材料。 此外，在至少一个实施例中，一个或两个钳口可以是预先切割的，远离切割构件的纵向轴线。 因此，在各种实施例中，可以减少推进切割构件和/或关闭夹爪所需的总体力。
