    摘要： The cross section of a curved portion of a curved cannula is oval shaped. The oval is oriented such that a major axis of the oval is generally aligned with the curved portion's bend radius. In one aspect, the cannula tube is ovalized so that the radius of curvature of an interior wall approaches the outer radius of an instrument component that contacts the curved portion during instrument insertion. In this first aspect, a wider contact patch area between the instrument component and the cannula results, which reduces friction and stick-slip during insertion. In another aspect, the cannula tube is ovalized so that the radius of curvature of an interior wall is less than the outer radius of an instrument component that contacts the curved portion during instrument insertion. In this second aspect, two contact patches are established between the instrument component and cannula, which also reduces friction and stick-slip during instrument insertion. Also disclosed is a cannula orientation marking that changes circumferential orientation along a length the curved cannula to help a person who is inserting the cannula to properly twist the cannula during insertion.

    摘要翻译： 弯曲套管的弯曲部分的横截面是椭圆形的。 椭圆的取向使得椭圆的长轴大致与弯曲部分的弯曲半径对齐。 一方面，套管管是椭圆形的，使得内壁的曲率半径接近器械插入期间接触弯曲部分的器械部件的外半径。 在该第一方面中，导致器械部件和套管之间的较宽的接触斑块区域，这减少了插入期间的摩擦和粘滑。 另一方面，插管管是椭圆形的，使得内壁的曲率半径小于器械插入期间接触弯曲部分的器械部件的外半径。 在该第二方面，在器械部件和插管之间建立了两个接触贴片，这也减少了器械插入期间的摩擦和粘滑。 还公开了一种套管定向标记，其沿着弯曲套管的长度改变周向定向，以帮助插入套管的人在插入期间适当地扭转套管。

    摘要： A compliant surgical device such as a flexible entry guide employs tendons to operate or steer the device and attaches asymmetric or constant force spring systems to control tension in the tendons. As a result, the surgical device can be compliant and respond to external forces during a surgical procedure without rapidly springing back or otherwise causing a reaction that damages tissue. The compliance also permits manual positioning or shaping of the device during or before insertion for a surgical procedure without damaging the tendons or connections of the tendons within the device or to a backend mechanism.

    摘要翻译： 诸如柔性进入引导装置之类的柔性外科手术装置使用肌腱来操作或操纵装置并附接不对称或恒定的力弹簧系统以控制肌腱中的张力。 结果，手术装置可以在外科手术过程中顺应并响应外力，而不会迅速回弹或以其他方式引起损伤组织的反应。 顺应性还允许在用于外科手术的插入期间或插入之前手动定位或成形装置，而不会损坏装置内的肌腱或肌腱的连接处或后端机构。
