目的：用外科放大镜进行放大，具有观察灵活、立体感广、深度感觉上级、比瞳孔大的物镜透镜增光等明显优点。然而，由于屈曲姿势和疲劳，连续使用这些放大镜会导致外科医生颈部拉伤。为了最大限度地减少应变和疲劳，最大限度地发挥双眼望远镜的优势和性能，我们已经开发出一种新颖的光学design.METHODS：为了让观察手术领域与外科医生的脖子和眼睛在一个直线的位置，望远镜的光路成角度向下与屋顶棱镜。为了获得最高的图像质量，我们采用了开普勒实像光学系统。结果：经过3年多的500多个程序的实际试验，光学系统、透镜的精加工和组装都得到了完善。新的符合人体工程学设计的光学系统在低到中等放大率范围内提供与立式显微镜相当的出色图像质量，同时有效地减少了在下方手术区域中工作的外科医生的颈部弯曲，并减轻了外科医生在连续使用数小时期间的疲劳。
OBJECTIVE: Magnification by surgical loupes has the distinct merits of agility and nimbleness in observation, a wide stereo base effectuating superior depth sensation, and light augmentation by an objective lens that is larger than the pupil. However, continuous use of these loupes causes neck strain for surgeons as a result of flexion posture and fatigue. To minimize the strain and fatigue and maximize the advantages and performance of binocular telescopes, we have developed a novel optical design.METHODS: To allow observation of the operative field with the surgeon's neck and eye in a straight position, the light path of the telescopes was angulated downward with roof prisms. For maximum image quality, Keplerian real-image optics were adopted.RESULTS: The optics, finishing of the lens, and assembly were perfected through practical trials of more than 500 procedures over a period of 3 years.CONCLUSION: The new ergonomically designed optics provide excellent image quality comparable to standing microscopes in the low to medium range of magnification, while effectively reducing the neck flexion of surgeons working in the operative field below and relieving the surgeon's fatigue during hours of continuous use.
