摘要：
A bone screw includes a screw shaft extending longitudinally along a screw axis and a screw head extending from a proximal end of the screw shaft and configured to be releasably coupled to a surgical tool. The bone screw also includes a through hole defining a through hole axis and extending through the screw head, the through hole axis intersecting the screw axis at an acute angle a, the through hole being adapted to receive therein a second screw and tapering from a first end at a proximal end of the screw head to a second end opening to an outer surface of the screw head.一種骨螺釘,包括沿螺釘軸線縱向延伸的螺釘桿和從所述螺釘桿的近端伸出並且被設置為能與手術工具可拆卸地連接的螺釘頭。所述骨螺釘還包括界定了通孔軸線並延伸通過所述螺釘頭的通孔,所述通孔軸線與所述螺釘軸線以銳角α相交,所述通孔被設定為能在其中容納第二螺釘,並從所述螺釘頭近端的第一端至開口於所述螺釘頭外表面的第二端逐漸變窄。
