It has been three decades since the operating microscope for otologic surgery was introduced into the United States. Today's surgical microscope is used not only for surgery but also for still photography, motion pictures, and videotape recordings. The needs of photography are such that additional fiberoptic light sources or strobe flash units are often attached to the operating microscope for illumination during photography. Each accessory uses a cord or cable to its electrical source, causing a myriad of cords to be serried alongside the extension arms of the microscope. Multiple cables frequently become entangled and create drag, which restricts the mobility of the microscope. A cable-carrying guide system of stainless steel rods shaped into open spirals of approximately one and one-half turns is described. The system contains the accessory cords while permitting full mobility of the microscope during surgical procedures.
耳科手术用手术显微镜被引入美国已有三十年了。如今的手术显微镜不仅用于手术，还用于静态摄影、电影拍摄和录像。摄影的需求使得在摄影时，常需在手术显微镜上附加额外的光纤光源或频闪闪光灯装置进行照明。每个附件都通过一根电线或电缆连接到电源，导致无数根电线沿着显微镜的延长臂密集排列。多根电缆经常缠结并产生拖拽力，这限制了显微镜的移动性。本文描述了一种由不锈钢杆制成的电缆承载导向系统，该系统呈约一圈半的开放螺旋形状。该系统在容纳附件电缆的同时，允许显微镜在手术过程中完全自由移动。
