    • An elastic band for ligating tissue within a living body comprises an inner tissue engaging surface which, when in an operative position within the body, surrounds and directly contacts the tissue. At least a portion of the inner tissue engaging surface defines a plurality of discontinuities formed by one of projections and depressions. A method of ligating tissue within a living body using such a ligating band comprises the steps of positioning the elastic band, which has been stretched to increase the size of a central opening extending therethrough, adjacent to a portion of tissue to be ligated. The tissue to be ligated is then drawn through the central opening of the elastic band and the elastic band is released so that the size of the central opening decreases to grip the tissue received therein.
    • 用于在生物体内结扎组织的弹性带包括内部组织接合表面,其在身体内的操作位置包围并直接接触组织时。 内部组织接合表面的至少一部分限定由突起和凹陷之一形成的多个不连续部分。 使用这种结扎带在生物体内结扎组织的方法包括以下步骤:将被拉伸的弹性带定位成邻近待连接组织的一部分,以增加延伸穿过其中的中心开口的尺寸。 然后将要连接的组织通过弹性带的中心开口被拉伸,弹性带被释放,使得中心开口的尺寸减小以夹持其中接收的组织。

    • A surgical access device can comprise a working channel providing a first lumen having an axial opening for insertion of a surgical instrument having an outflow channel, the first lumen having a fluid inlet for allowing fluid flow through the working channel and into the body, wherein fluid flows out of the body through the outflow channel of the surgical instrument; and a optical channel providing a second lumen for a visualization element and a light source, wherein the working channel comprises a larger cross-sectional area than the cross-sectional area of the optical channel. The surgical access device can further comprise a seal apparatus coupled to the working channel and configured to receive the surgical instrument, the seal apparatus comprising a first seal portion and a second seal portion, the first seal portion configured to close the fluid path into the seal apparatus, and the second seal portion configured to form a seal with the surgical instrument.
    • 外科进入装置可以包括工作通道,其提供具有用于插入具有流出通道的外科器械的轴向开口的第一管腔,第一管腔具有用于允许流体流过工作通道并进入体内的流体入口,其中流体 通过手术器械的流出通道流出身体; 以及提供用于可视化元件和光源的第二内腔的光学通道,其中所述工作通道包括比所述光学通道的横截面积更大的横截面面积。 外科进入装置还可以包括联接到工作通道并被配置为接收外科器械的密封装置,密封装置包括第一密封部分和第二密封部分,第一密封部分构造成将流体通道封闭到密封件 装置,并且第二密封部分被配置为与外科器械形成密封。
