    • A device (10) is provided which includes an elongated cannula (20) having a first inner diameter (DI) and an outer diameter (DO) sized for percutaneous introduction into a patient. The cannula (20) defines a working channel (25) between its ends (21, 22) which has a second diameter (D2) equal to the diameter (DI) of the cannula sized for receiving a tool therethrough. An elongated viewing element (50) is engageable to the cannula (20) adjacent the working channel (25), preferably by a fixture (30, 170). The fixture (30, 170) includes a housing/body (31, 171) attachable to the proximal end (22) of the cannula (20). The housing (31) defines an optics bore (60, 180) to support a viewing element (50) for translation and rotation relative to the cannula (20) so that the longitudinal axis of the optics bore (60, 180) will translate parallel to and rotate about the longitudinal axis of the working channel (25). Methods are also provided for performing surgeries percutaneously with direct visualization and without the requirement for a fluid-maintained workspace.
    • 提供了一种装置(10),其包括具有第一内径(DI)和外径(DO)的细长套管(20),所述第一内径(DI)和外径(DO)的尺寸用于经皮引入患者体内。 套管(20)在其端部(21,22)之间限定工作通道(25),该工作通道具有等于套管的直径(DI)的第二直径(D2),该直径(DI)的尺寸用于容纳穿过其中的工具。 细长的观察元件(50)可以优选地通过固定装置(30,170)与邻近工作通道(25)的插管(20)接合。 固定器(30,170)包括可附接到套管(20)的近端(22)的壳体/主体(31,171)。 壳体(31)限定光学孔(60​​,180)以支撑观察元件(50),用于相对于套管(20)的平移和旋转,使得光学孔(60​​,180)的纵向轴线将平行平移 绕工作通道(25)的纵向轴线旋转并旋转。 还提供了用于通过直接可视化经皮进行手术并且不需要流体维持的工作空间的方法。
