The sitting position is favorable for microsurgical procedures applied to posterior midline pathologies in both the supra- and infratentorial regions. The dimensions of the microscope corpus affect the device's comfort and handling in the hands of the microneurosurgeon for such procedures. A shorter microscope corpus provides more favorable intraoperative ergonomics for surgical practice.
Evaluation of the most comfortable microscope for its application in microsurgical procedures in the sitting position as determined by ocular-corpus length.
Six modern surgical microscopes were tested and evaluated regarding their ocular-corpus lengths and working distances: the Mitaka MM90, Zeiss Kinevo 900, Zeiss Pentero 900, Leica M530, Zeiss Neuro NC4, and Möller-Wedel Hi-R 1000. The ocular-corpus lengths vary between 270 and 380 mm. The Mitaka MM90 microscope has the shortest ocular-corpus length at 270 mm.
The ocular-corpus length determines the predominant part of the lever arm, which affects the fatigue of the surgeon. By virtue of its short ocular-corpus length, the Mitaka MM90 is currently the most favorable microscope for microsurgical procedures using a sitting position.
坐姿有利于对幕上和幕下区域后中线病变进行显微外科手术。显微镜镜身的尺寸会影响显微神经外科医生在进行此类手术时使用该设备的舒适度和操作便利性。较短的显微镜镜身可为手术操作提供更有利的术中人体工程学条件。
根据目镜-镜身长度评估最适合在坐姿显微外科手术中使用的显微镜。
对六台现代手术显微镜的目镜-镜身长度和工作距离进行了测试和评估，分别是三鹰MM90、蔡司Kinevo 900、蔡司Pentero 900、徕卡M530、蔡司Neuro NC4和莫勒-韦德尔Hi-R 1000。目镜-镜身长度在270至380毫米之间变化。三鹰MM90显微镜的目镜-镜身长度最短，为270毫米。
目镜-镜身长度决定了杠杆臂的主要部分，这会影响外科医生的疲劳程度。凭借其较短的目镜-镜身长度，三鹰MM90目前是坐姿显微外科手术中最适用的显微镜。
