The basic idea of video-microsurgery is the improvement of ergonomic conditions in microsurgical procedures by replacing the bulky operating microscope with a compact videosystem.
To specify optical requirements on a videosystem for microsurgical intracranial procedures in neurosurgery.
During 27 microsurgical intracranial procedures (12 cerebellopontine angle and 15 supratentorial) zoom factor, focus distance and illumination parameters of the operating microscope were continuously recorded. Ergonomic aspects were documented as well.
The zoom factor ranged from 1.7 to 13.5 in CPA procedures and from 1.4 to 13.4 in supratentorial procedures. The focus distance ranged from 180 mm to 367 mm in CPA procedures and from 188 mm-472 mm in supratentorial procedures.
From an optical point of view current operating microscopes meet the requirements of intracranial microneurosurgery. However, ergonomically further developments are highly desirable. Video microsurgery is a promising field and could hold a solution to this problem.
视频显微镜手术的基本理念是通过用紧凑的视频系统取代庞大的手术显微镜来改善显微手术的人体工程学条件。
为神经外科颅内显微手术指定视频系统的光学要求。
在 27 例颅内显微手术（12 例桥小脑角和 15 例幕上）中，连续记录手术显微镜的变焦因子、焦距和照明参数。同时记录了人体工程学方面的情况。
CPA 手术的变焦因子范围为 1.7 至 13.5，幕上手术的变焦因子范围为 1.4 至 13.4。CPA 手术的焦距范围为 180 毫米至 367 毫米，幕上手术的焦距范围为 188 毫米至 472 毫米。
从光学角度来看，目前的手术显微镜满足颅内显微神经外科的要求。然而，从人体工程学的角度来看，进一步的发展是非常可取的。视频显微镜手术是一个有前途的领域，可能为解决这一问题提供了一种解决方案。
