摘要：
A system (10) for direct visualization of the spine includes a catheter (12) and a fiber-optic bundle (20) disposed within the catheter (12) which is connected to a light source and camera. The optical bundle is connected (26) to the proximal end of the catheter to permit rotation of the bundle relative thereto. A mechanism for deflecting the catheter tip provides a conical viewing angle (13) for the fiber-optic bundle and assists in steering the catheter through the spinal space. The mechanism includes a deflection wire (57) extending through the catheter and affixed at the distal end (83) thereof. The proximal end of the deflection wire is affixed to a sleeve (58) slidably disposed around the catheter to contact a stop surface (59) as the catheter and deflection wire are moved. The stop surface prevents further movement of the catheter causing tension in the wire between the sleeve and the wire's securement to the catheter, thereby bending the catheter tip in the direction of the securement.
摘要（中）：
用于脊柱直接可视化的系统（10）包括设置在导管（12）内的导管（12）和光纤束（20），其连接到光源和照相机。 光束被连接（26）到导管的近端以允许束相对于其旋转。 用于偏转导管末端的机构提供用于光纤束的锥形视角（13），并且有助于将导管转向脊柱空间。 该机构包括延伸穿过导管并固定在其远端（83）处的偏转线（57）。 当导管和偏转线移动时，偏转线的近端固定到可滑动地设置在导管周围的套筒（58），以接触止动表面（59）。 止动表面防止导管的进一步移动，导致套管和电线的固定件之间的电线中的张力导向导管，从而沿着固定方向弯曲导管尖端。
