摘要： A method of controlling a surgical intervention to a bone comprises obtaining a three-dimensional image or multiplanar reconstruction of the bone, defining a position and an axis of intervention on the three-dimensional image or multiplanar reconstruction of the bone, and controlling an orientation of an intervention instrument equipped with an orientation sensor during the surgical intervention by evaluating a signal provided by the orientation sensor. The method further comprises referencing the intervention instrument with respect to the bone before the surgical intervention by arranging the intervention instrument in relation to an anatomic landmark and rotating the orientation sensor into a predefined position. The method allows for efficiently achieving correct orientation and position of the intervention instrument in bone surgical intervention. Furthermore, the method provides an efficient real-time control at comparably low efforts. Still further, with the method radiation exposure to the operational staff as well as patients can be reduced.

摘要： A method of controlling a surgical intervention to a bone (31) comprises: obtaining a three-dimensional image or multiplanar reconstruction of the bone (31), defining a position and an axis of intervention on the three-dimensional image or multi-planar reconstruction of the bone (31), and controlling the orientation of an intervention instrument (1) equipped with an orientation sensor (2) during the surgical intervention by evaluating a signal provided by the orientation sensor (2). The method further comprises referencing the intervention instrument (1) with respect to the bone (31) before the surgical intervention by arranging the intervention instrument (1) along an anatomic landmark (32) being an edge of the bone (31) and rotating the orientation sensor (2) into a predefined position, or by arranging the intervention instrument (1) essentially perpendicular to an anatomic landmark (32) being an essentially flat surface of the bone (31) and rotating the orientation sensor (2) into a predefined position. The method according to the invention allows for efficiently achieving correct orientation and position of the intervention instrument in a bone surgical intervention. Furthermore, the method according to the invention provides an efficient real-time control at comparably low efforts. Still further, with the method according to the invention radiation exposure to the operational staff as well as patients can be reduced.

摘要翻译： 控制对骨骼（31）的外科手术的方法包括：获得骨骼（31）的三维图像或多平面重建，在三维图像或多平面重建上定义干涉的位置和轴线 ，并且通过评估由所述取向传感器（2）提供的信号来控制在手术介入期间配备有方位传感器（2）的介入器械（1）的取向。 该方法还包括通过沿着作为骨骼（31）的边缘的解剖标志（32）布置介入器械（1），在外科手术之前相对于骨头（31）参考介入器械（1） 或者通过将干涉仪器（1）基本上垂直于作为骨骼（31）的基本上平坦的表面的解剖学标记（32）布置并将定向传感器（2）旋转到预定义的位置 位置。 根据本发明的方法允许在骨手术介入中有效地实现干预器械的正确取向和位置。 此外，根据本发明的方法在相当低的努力下提供了有效的实时控制。 此外，根据本发明的方法，可以减少对操作人员以及患者的辐射照射。
