We designed a suction fixation system for the radiosurgical treatment of intraocular malignancies with the Leksell Gamma Knife. Our device consists of a circular suction chamber and an adjustable unit which is fixed to the Leksell stereotactic head frame. All components are made of plastic in order to avoid artifacts in CT or MRI. A permanent suction of 600-800 mbar is provided by a standard vacuum pump, powered by a portable battery. In the Gamma Knife Unit of the Neurosurgical Department at the University of Vienna, we successfully used this device. Up to April 1994 we successfully performed 25 radiosurgical treatments in 12 patients with large or extra-large uveal melanomas and in 1 patient suffering from a choroidal metastasis.
我们设计了一种用于使用Leksell伽玛刀对眼内恶性肿瘤进行放射外科治疗的吸引固定系统。我们的设备由一个圆形吸引腔和一个固定在Leksell立体定向头架上的可调节装置组成。所有部件均由塑料制成，以避免在CT或MRI中产生伪影。由便携式电池供电的标准真空泵提供600 - 800毫巴的持续吸力。在维也纳大学神经外科的伽玛刀治疗单元中，我们成功使用了该设备。截至1994年4月，我们成功地对12例患有大或超大脉络膜黑色素瘤的患者以及1例患有脉络膜转移瘤的患者进行了25次放射外科治疗。
