本申请提供一种用于髋关节置换手术的导航定位系统,包括：前端击打组件、标定架组件、旋转组件以及手柄组件，
所述旋转组件分别连接所述前端击打组件、所述标定架组件以及所述 手柄组件，所述旋转组件在转动时，带动所述标定架组件同步旋转，所述标定组件为所述导航定位系统提供所述前端击打组件的坐标信息；
所述手柄组件远离所述旋转组件的一端，在受到打击力的情况下，将所承受的打击力经由所述前端击打组件传递至目标位置。
本申请的髋关节置换手术导航定位系统可旋转可停在特定角度，通过转动旋转组件，可以带动标定架组件的旋转，从而很好地解决了现有技术因为直压配杆长期受到击打，导致直压配杆的标定架位置发生变化，操作人员无法通过标定架组件为所述导航定位系统提供所述前端击打组件的坐标信息，从而导致定位不准确的问题。进一步地，实际操作人员能够根据实际需要，转动标定架实现精确定位，并且由于可转动式的结构，便于实际操作。
本申请实施例的第二方面，提供一种应用于如上所述的用于髋关节置换手术导航系统的使用方法，所述方法包括：
将前端击打组件的髋臼杯假体置于人体髋臼窝内；
转动旋转组件，以带动标定架组件转动；
基于转动后的标定架组件的第一位置信息，确定所述前端击打组件的第二位置信息；
在确定所述第二位置信息满足预设位置条件时，压配所述髋臼杯假体。
需要说明的是，由于前端击打组件相对于标定架组件的位置是固定的，因此，通过确定标定架组件上的反射光球的位置坐标信息，便可以得到前端击打组件的实际位置坐标信息(也就是上述提到的第二位置信息)。可选地，确定前端击打组件的实际位置坐标信息，可以是确定前端击打组件的髋臼杯假体的实际位置坐标信息。在确定出前端击打组件的实际位置坐标信息之后，若确定实际位置坐标信息与理论位置坐标信息的差值小于或等于第一预设差值(即确定第二位置信息满足预设位置条件)，则可以基于确定出的实际位置坐标信息压配髋臼杯假体，以使髋臼杯假体置入人体的髋臼窝处。若确定实际位置坐标信息与理论位置坐标信息的差值大于第一预设差值(即确定第二位置信息不满足预设位置条件)，则调整前端击 打组件的位置，直至前端击打组件的实际位置坐标信息与理论位置坐标信息的差值小于或等于第一预设差值时为止。
可以理解的是，本申请方法实施例的有益效果，可以参考前述用于髋关节置换手术的导航定位系统实施例的有益效果，本申请实施例在此不再赘述。

基于所述空间信息，通过所述前端击打组件压配目标对象。
示例性地，前端击打组件包括中心轴和髋臼杯假体，中心轴的一端与髋臼杯假体通过螺纹连接。本申请实施例手术机器人系统，前端击打组件的髋臼杯假体，置于髋臼7的髋臼窝内，由于髋臼杯假体相对于标定架组件的位置信息是可以通过坐标转换得到的，通过获取标定架组件的位置信息，实际上就可以得到髋臼杯假体的位置信息。
通过光学导航仪定位标定架组件的空间位置信息，并将空间信息传输至光学导航仪显示器上显示，实际操作人员能够根据实际需要，能够准确获取相应的位置信息，便于实际操作。
可以理解的是，本申请手术机器人系统实施例的有益效果，可以参考前述髋关节置换手术导航定位系统实施例的有益效果外，本申请实施例手术机器人系统，前端击打组件的击打头，相对于标定架组件的位置信息是可以通过坐标转换得到的，通过获取标定架组件的位置信息，实际上就可以得到击打头的位置信息。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或 者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
