The author reports his experience with a stereotactic apparatus which gives more protection to patients during stereotactic operations. This apparatus allows the verification of the centrage of the target before puncturing the brain with the needle. In the most common stereotactic systems there is a headframe with three or four pins for the fixation to the skull. This apparatus is more simple: there is no frame and there is only one point of fixation to the skull: a small, L-shaped, aluminum bar, fixed in the right prefrontal region with two small screws. Because this system has only one point of fixation to the skull, it is movable like a bell. Besides the possibility of a direct verification of the centrage of the target, that has induced the author to study a new stereotactic apparatus for CT-guided stereotaxy, the small size of the apparatus means that it does not interfere with surgery in microneurosurgical stereotactic directed operations. This stereotactic apparatus can be used with CT-scan because it is aluminium with some parts in brass. The system, moreover, can be used whether scanner-dependent or scanner-independent, using two different softwares for calculation of the centrage of the target.
作者报告了他使用一种立体定向设备的经验,该设备在立体定向手术期间能为患者提供更多保护。这种设备允许在使用针穿刺脑部之前验证靶点的中心位置。在最常见的立体定向系统中,有一个带有三到四个用于固定在颅骨上的销钉的头架。这种设备更简单:没有框架,只有一个固定在颅骨上的点:一根小的L形铝条,用两个小螺丝固定在右前额叶区域。由于该系统在颅骨上只有一个固定点,它像钟一样可移动。除了可以直接验证靶点的中心位置外,这促使作者研究一种用于CT引导立体定向术的新型立体定向设备,该设备的小尺寸意味着它不会干扰显微神经外科立体定向手术中的操作。这种立体定向设备可以与CT扫描仪一起使用,因为它是铝制的,有些部件是黄铜的。此外,无论依赖扫描仪还是不依赖扫描仪,该系统都可以使用两种不同的软件来计算靶点的中心位置。
