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.
