The registration of magnetic navigation system for surgery

新型磁性材料装置的研究与开发：2001年，我们成功地将新型磁性材料(Neo Max 50)切割加工成小块植入人体。1.6 mm八角形柱形磁体具有足够的磁力，是该磁导航系统应用的最佳形式。我们可以知道这个磁性制造器在15厘米的范围内在三个磁性传感器臂之间移动的位置，并进行实时处理。为了测量微小的磁场，我们制作了三个磁通门磁传感器的小部件，每个传感器长5毫米，直径2毫米。16位数字数据转换器：我们最新开发了两套16位数字数据转换器，将精确的定位数据送入计算机系统，噪声小。磁力机检测计算算法的研究与开发：我们开发了快速的非…更多基于Linux和Java的逆磁计算方法应用于实际操作中。试行胸内窥镜手术磁导航：充分了解磁标记位置、磁标和磁通门传感器的检测算法，建立了胸内窥镜手术磁导航系统。动物实验：我们建立了磁导航手术的磁导航系统，具有直观的视野和显示的监视器，在猪的手术中，多骨的胸腔具有长而窄的长度和宽度，而猪肺的体积几乎是人类的一半。在此期间，我们使用了许多不锈钢制成的手术器械，因此，它们有时会对磁性标记器周围的磁场产生干扰，这证明了我们的计算计算机系统无法检测到目标标记物的正确位置。在这些结果中，我们真诚地需要钛制造的手术器械。较少

The Research and Development of the settings with new magnetic material:In 2001,we succeeded in cutting and processing of new magnetic material (Neo Max 50) into small pieces to be embedded in the human body. The 1.6 mm octagonal column shaped magnet has the enough magnetic force, and it is the best form for the applications in this magnetic navigation system. We can know where this magnetic maker moves between three magnetic sensor arms within the limits of fifteen centimeters cubed with real-time processing. In order to measure the fine magnetic field, we had made the small components of three fluxgate magnetic sensors, and each sensor is five millimeter long and two millimeter in diameter.Sixteen bit Digital Data Converter:We newly developed two sets of the 16 bit Digital data converter to send the precise positioning data into computer system with few noise.The Research and Development of the calculation algorism for the detection of magnetic maker:We have developed the fast and un … More ique calculating methods based on the Linux and JAVA for reverse magnetic problem to use in the practical operation.The trial for magnetic navigation surgery for thoracoscopic surgery:We fully appreciated the calculation algorism for the detection of magnetic maker position, magnetic marker and fluxgate sensors, and we set up the magnetic navigation system for thoracoscopic surgery. On the monitor display, we could know the maker position exactly as a flicker stick marker with this system.Animal experiments:We set up the magnetic navigation system for magnetic navigation surgery with direct view scope and display monitor.In the pig surgery, the bony thoracic cavity has the long length and narrow width, and the volume of the pig lung is almost the half of human one. In this time, we have used many surgical instruments made with stainless steel, therefore, they sometimes disturb the magnetic fields around the magnetic marker, after that, it was proved for our calculating computer system could not detect the right position of the target marker. In these results, we sincerely need the surgical instrument made in Titanium. Less
