    • A vertebral column support device is assembled by means of clamping. The device includes bone screw- or hook-type vertebrae anchoring elements, the elements consisting of a threaded cylindrical part (5) and a stop collar (7). A fixing nut (8) can be screwed on the threaded cylindrical part (5) in order to fix a connecting sliding piece (4) which is mounted on a securing rod (3) having a circular section. In order to insure that the rod (3) and the connecting sliding piece (4) are secure, the securing rod (3) is clamped in a transverse groove (17) in the connecting sliding piece (4) using a clamp screw (21) and a little clamp (22) which is mounted in the corner of the groove. In this way, the inventive device is more rigid and can better support the vertebrae and, moreover, the device can be positioned and adjusted much more easily.
    • 脊柱支撑装置通过夹紧装配。 该装置包括骨螺钉或钩型椎骨锚固元件,所述元件由螺纹圆柱形部件(5)和止动套环(7)组成。 固定螺母(8)可以拧在螺纹圆柱形部分(5)上,以便固定安装在具有圆形截面的固定杆(3)上的连接滑动件(4)。 为了确保杆(3)和连接滑动件(4)固定,使用夹紧螺钉(21)将固定杆(3)夹紧在连接滑动件(4)中的横向槽(17)中 )和安装在槽的角部的小夹具(22)。 以这种方式,本发明的装置更加刚性并且可以更好地支撑椎骨,此外,可以更容易地对装置进行定位和调整。

    • In a device including an anterior plate for vertebral column support, there is at least one connecting sliding piece which is used to connect an anchoring screw to a securing rod. The securing rod is inserted into a cylindrical bearing and is fixed using a tightening device including a small clamp and a tightening screw. The connecting sliding piece includes at least one tip which extends away from the cylindrical bearing for the securing rod, in a direction which converges with the axis of the anchoring screw. In this way, the connecting sliding piece is provisionally fixed by pressing same against a vertebra, the anchoring screw is subsequently screwed in place and, finally, the securing rod is inserted laterally into the cylindrical bearing before being tightened using the small clamp and the tightening screw. The device is designed for anterior implantation on a vertebral column.
    • 在包括用于脊柱支撑的前板的装置中,存在用于将锚定螺钉连接到固定杆的至少一个连接滑动件。 固定杆插入圆柱形轴承中,并使用包括小夹具和紧固螺钉的紧固装置固定。 连接滑动件包括至少一个尖端,该尖端沿着与固定螺钉的轴线收敛的方向远离用于固定杆的圆柱形轴承延伸。 以这种方式,通过将其压靠在椎骨上来临时固定连接的滑动件,然后将锚定螺钉拧入就位,最后将固定杆横向插入到圆柱形轴承中,然后使用小夹具紧固并拧紧 拧。 该装置设计用于脊椎前柱植入。
