本申请涉及骨科手术器械技术领域，具体而言，涉及一种内嵌钢槽的膝关节截骨定位导向系统、压配系统及方法。
骨科手术机器人前端工具是用于骨科手术过程中的医疗器械。
当前，在进行膝关节置换手术时，通常需要利用固定于膝关节的截骨导板，借助动力摆锯沿着开设于截骨导板的切割导向槽对股骨进行切割。为了达到预期的导向切割精度，在摆锯切割前，截骨导板相对于膝关节的稳定性至关重要。

所述钢槽安装柱54设有三个，其中两个所述钢槽安装柱54分别固接于所述固定安装面51，另一个所述钢槽安装柱54固接于所述调位滑块53，用以使另一个钢槽安装柱54能够随调位滑块53同步基于调位滑轨52灵活调整位置，三个所述钢槽安装柱54分别与所述截骨导板本体2的三个导向孔21之间一一同轴对应，且其对应方向与所述压配导轨33的延伸方向相同，用以使得三个钢槽安装柱54在随压配滑座5基于压配导轨33滑动时，能够分别精确对应装配至三个导向孔21内，进而实现对于导向钢槽7在导向孔21内部的压配安装。
优选地，所述调位滑轨52的侧部固接有所述限位块55，用以通过限位块55有效限制调位滑块53的滑动位置，避免滑脱。
所述压配手扭6的一侧端固接有螺纹杆，所述手扭定位部32开设有螺纹孔，所述压配手扭6的螺纹杆螺合装配于所述手扭定位部32的螺纹孔，且所述螺纹杆抵接于所述压配滑座5背离所述截骨导板本体2的一侧端，用以可通过旋动压配手扭6推动压配滑座5沿着压配导轨33作直线进给运动。
所述导向钢槽7设有三个，且三个所述导向钢槽7分别一一对应间隙套装于三个所述钢套安装柱54，用以使导向钢槽7能够随钢套安装柱54同步作直线进给运动，并最终将导向钢槽7稳定压配至导向孔21内。
该实施例中的利用压配系统对内嵌钢槽的膝关节截骨定位导向系统进行压配的压配方法，包括如下步骤：
S1：旋动后退压配手扭6，并操控压配滑座5滑至底安装座3靠近压配手扭6的一侧端，以此形成截骨导板本体2的安装空间；
S2：将截骨导板本体2限位安装至设于底安装座3的导板定位支座4保持固定；
S3：在压配滑座5朝向截骨导板本体2一侧的钢套安装柱54分别间隙安装配置导向钢槽7；
S4：再次旋动压配手扭6，压配手扭6基于底安装座3的手扭定位部32逐步顶进，压配滑座5受顶进作用沿底安装座3逐步滑动靠近截骨导板本体2；
S5：在间隙配置有导向钢槽7的钢套安装柱54到达截骨导板本体2的导向孔21的情况下，继续旋动压配手扭6，将导向钢槽7压配于截骨导板本体2的导向孔21内；
S6：在导向钢槽7压配完成后，再次旋动后退压配手扭6，并将压配滑座5拉出截骨导板本体2，从而完成导向钢槽7在导向孔21的压配过程；
S7：对在导向孔21内部压配后的导向钢槽7利用通止规进行检验；
S8:具体的，在完成导向钢槽7在导向孔21的压配过程之后，将预设规格(例如直径2.9mm)的通止规分别插入压配后的导向钢槽7内，判断是否进入深度不小于预设距离(例如10mm)，若是，则为符合要求的截
骨导板本体2，若否，则为不符合要求的截骨导板本体2。
