    摘要： A tubular, fluid-controlled bending neck is provided for an elongated flexible probe, such as a video borescope. An elongated tubular elastomeric bladder is fitted to a proximal connector that fits onto a distal end of the probe insertion tube, and a distal fitting seals the distal end of the bladder. A tubular braid is disposed over the bladder to confine the same and is mechanically attached to the distal fitting and to the proximal connector. The connector provides communication of fluid presure from a controlled fluid pressure source to be interior of the bladder. An elastically bendable, by axially substantially incompressible spine is disposed at the interface between the bladder and the braid. This spine is preferably set or biased to be curved into one bending direction. As fluid pressure is applied to the bladder, the bladder inflates laterally. This shortens the braid on the side away from the spine, thereby bending the neck in the opposite direction. By applying a pressure intermediate between a zero pressure and the pressure required for full bending the bending neck will assume a straight orientation.

    摘要翻译： 为细长的柔性探针（例如视频内窥镜）提供管状流体控制的弯曲颈部。 细长的管状弹性体囊被装配到近端连接器上，该近端连接器配合到探针插入管的远端，并且远端配件密封囊的远端。 管状编织物设置在膀胱上方以限制其上并机械地连接到远端配件和近端连接器。 连接器提供从受控流体压力源到囊的内部的流体压力的连通。 弹性可弯曲但轴向上基本上不可压缩的脊柱设置在囊和编织物之间的界面处。 该脊椎优选地设置或偏置成弯曲成一个弯曲方向。 当液体压力施加到膀胱时，膀胱横向膨胀。 这样可以缩短编织物远离脊柱的一侧，从而使颈部沿相反的方向弯曲。 通过在零压力和完全弯曲所需的压力之间施加中间压力，弯曲颈部将呈现直线取向。
