An endoscopic aneurysm clip applicator: preliminary development.
Visualization of an aneurysm and its associated vessels is necessary for the proper application of aneurysm clips. Microscopes provide binocular magnification and excellent illumination but often visualization is obscured by overriding vessels and the limitation of the operative approach. If this occurs the aneurysm may be incompletely clipped or small perforators may be included in the clip. In an attempt to improve visualization during aneurysm clipping we have incorporated a small endoscope into the aneurysm clip applicator so that the tips of the clip can be observed at all times. Here we report our initial experimental results with this instrument.
