研制了一台直径8 mm、焦距20 cm的硬性透镜望远镜，用于开放显微手术。该望远镜被连接到一个3芯片高清数码相机上，然后连接到一个高清监视器上。气动示波器支架允许重新定位。并与台阶式1 mm网格纸手术显微镜的光学质量进行了比较。在活猪模型上用望远镜系统(高清晰度外窥镜系统)进行开颅手术和显微外科解剖。即使在高倍率下，高清晰度的外视镜系统也能提供与手术显微镜相媲美的图像质量。该系统在神经外科手术中易于操作和舒适。缺乏立体视觉是该系统的一个相对缺点，但通过重复手术来弥补。总体而言，这种基于望远镜的原型系统可以与操作显微镜的光学质量和视场相媲美。如果进一步完善，该系统将在许多显微外科学科中得到广泛应用。
An 8-mm diameter rigid lens telescope with a focal distance of 20 cm was developed for open microsurgery. The telescope was attached to a 3-chip high-definition digital camera and then to a high-definition monitor. A pneumatic scope holder permitted repositioning. The optical quality of the device was compared with the operating microscope with a step wedge and 1-mm grid paper. Craniotomies and microsurgical dissections with the telescope system (high-definition exoscope system) were performed in a live pig model. The high-definition exoscope system provided image quality that rivaled the operating microscope even at high magnification. The system was easy to manipulate and comfortable during neurosurgical operations. The lack of stereopsis was a relative drawback of the system but was compensated for with repeated procedures. Overall, this prototype telescope-based system rivals the operating microscope optical quality and field of view. With further refinement, this system could have widespread application in many microsurgical disciplines.
