Neuroendoscopy is increasingly used as an adjunctive tool in intracranial aneurysm surgery.
To assess the versatility of a prototype continuously variable-view rigid endoscope in visualizing the anterior cerebral artery complex.
In 5 formaldehyde-fixed, arterially injected specimens, a standard frontolateral approach was used on both sides. After meticulous microsurgical dissection using this approach, the prototype of a multivariable rigid endoscope (EndoCAMeleon; Karl Storz GmbH & Co, Tuttlingen, Germany) was inserted. It is a rigid endoscope that is capable of changing its angle of view while remaining stationary and shape invariant. We inspected the anterior cerebral artery complex, using and testing the capabilities of the device.
The continuously variable viewing mechanism enables the surgeon to adjust the field of view continuously and to optimize the visualization of the neurovascular structures. Because of the rigid tip combined with the continuously variable viewing mechanism, the need to move the endoscope within the surgical field was minimal. The field of view changes, but the tip itself hardly moves. The EndoCAMeleon was able to enhance both the visibility of the anterior cerebral artery complex and the accessibility of the A1 and A2 arterial walls to a range of approximately 270 degrees.
The EndoCAMeleon enhances the visibility of the anterior cerebral artery complex and facilitates endoscope-assisted inspection, planning of clip application, and clip control.
神经内镜越来越多地被用作颅内动脉瘤手术的辅助工具。
评估一种连续可变视角刚性内窥镜在可视化大脑前动脉复合体方面的多功能性。
在 5 个福尔马林固定、动脉内注射的标本中，两侧均采用标准的额侧入路。在使用这种方法进行精细的显微外科解剖后，插入了一种多变量刚性内窥镜（EndoCAMeleon；Karl Storz GmbH & Co，图特林根，德国）的原型。这是一种刚性内窥镜，能够在保持静止和形状不变的情况下改变其视角。我们使用和测试该设备的功能来检查大脑前动脉复合体。
连续可变的观察机制使外科医生能够连续调整视野，并优化对神经血管结构的可视化。由于刚性尖端与连续可变的观察机制相结合，因此在手术区域内移动内窥镜的需求最小。视野发生变化，但尖端本身几乎不动。EndoCAMeleon 能够增强大脑前动脉复合体的可视性，并增强对 A1 和 A2 动脉壁的可达性，可达约 270 度。
EndoCAMeleon 增强了大脑前动脉复合体的可视性，并有助于内窥镜辅助检查、夹应用的规划和夹控制。
