带有临时锁定装置的椎间植入物
摘要：
本发明涉及一种椎间植入物(1)，尤其是人造的椎间盘，包括一条中心轴线(2)、一个上件(3)、一个下件(4)和一个沿轴向设置在这两个件(3、4)之间的关节(9)，还包括可去除的锁定装置(21)，其中：A)上件(3)具有一个上对合面(35)、一个前侧的侧面(31)、一个背侧的侧面(32)和两个侧向的侧面(33、34)，并且上对合面(35)适用于贴靠在一个位于其上方的椎骨体的底板上；B)下件(4)具有一个下对合面(45)、一个前侧的侧面(41)、一个背侧的侧面(42)和两个侧向的侧面(43、44)，并且下对合面(45)适用于贴靠在一个位于其下方的椎骨体的盖板上；C)关节(9)包括一个凸面的带有一个第一关节面(10)的关节件(12)和一个与其互补的带有一个可滑动地支承在第一关节面(10)上的第二关节面(11)的关节壳(13)；D)所述两个件3、4的每一个都包括用于安装可临时固定的锁定装置(21)的机构(20)，所述锁定装置用于相互相对地固定所述两个件(3、4)；并且E)椎间植入物(1)包括至少一个可导入到机构(20)内和可去除的锁定装置(21)。
摘要（英）：

The invention relates to an intervertebral implant (1), especially an artificial disk, having a central axis (2), an upper part (3), a lower part (4), a joint (9) which is axially arranged between the two parts (3;4), and removable blocking means (21). According to the invention, A) the upper part (3) has an upper apposition surface (35), a ventral lateral surface (31), a dorsal lateral surface (32), and two end lateral surfaces (33;34), and the upper apposition surface (35) can be applied to the base plate of a vertebral body located above the plate; B) the lower part (4) has a lower apposition surface (45), a ventral lateral surface (41), a dorsal lateral surface (42), and two end lateral surfaces (43;44), and the lower apposition surface (45) can be applied to the covering plate of a vertebral body located beneath the plate; C) the joint (9) comprises a convex joint part (12) having a first joint surface (10) and a complementary joint shell (13) having a second joint surface (11) that is mounted on the first joint surface (10) in a sliding manner; D) each of the two parts (3;4) comprises means (20) for receiving temporarily fixable blocking means (21) for fixing the two parts (3;4) in relation to each other; and E) the intervertebral implant (1) comprises at least one blocking means (21) that can be introduced into the means (20) and removed from the same.
