    • A distractor (1) presenting a central portion (2); two partially threaded straight elements (3, 4) extending from opposite sides of the central portion (2) and connected to it by respective spherical articulated joints (5, 6); and two slides (7, 8), each movable axially along a respective straight element (3, 4). Each slide (7, 8) presents a prismatic main body (27); and two parallel arms (28) extending from the main body (27) and presenting respective aligned holes (29) through which the respective straight element (3, 4) fits. A regulating nut (31), movable along a respective straight element (3, 4) and interposed between the arms (28) of a respective slide (7, 8), provides for positioning each slide (7, 8) continuously and micrometrically along the respective straight element (3, 4).
    • 呈现中心部分(2)的牵引器(1); 两个部分螺纹的直线元件(3,4)从中心部​​分(2)的相对侧延伸并且通过相应的球形铰接接头(5,6)连接到它们; 和两个滑块(7,8),每个滑动件(7,8)都沿着相应的直线元件(3,4)轴向移动。 每个滑块(7,8)呈现棱镜主体(27); 和从主体(27)延伸的两个平行的臂(28),并且呈现相应的对准的孔(29),相应的直线元件(3,4)通过该孔配合。 可沿着相应的直线元件(3,4)移动并且插入在相应的滑块(7,8)的臂(28)之间的调节螺母(31)提供了连续地和微米地沿着每个滑块(7,8)定位 相应的直线元件(3,4)。
