多级脊骨固定锁定机构
摘要：
本发明描述了一种锁定机构和将固定装置(104)(例如骨螺钉)和稳定装置(106)(例如杆)的相对位置锁定的方法。锁定机构包括基座(102)，垫圈(108)和盖(110)。基座(102)包括底部(114)，构造成用于容纳固定装置(104)，从而使得底部(114)的插口(116)接合一部分固定装置(104)并且防止固定装置(104)完全从中通过。基座(102)还包括侧部(112)，其构造成用于容纳稳定装置(106)、垫圈(108)和盖(110)。当垫圈(108)和盖(110)与基座(102)完全接合接合时，固定装置(104)可以与稳定装置(106)无关地锁定。锁定机构还可以包括用于锁定稳定装置(106)的锁定元件。
摘要（英）：

Described is a locking mechanism and method of locking the relative positions of a fixation device (104) like a bone screw and of a stabilization device (106) like a rod. The locking mechanism includes a seat (102), a washer (108) and a cap (110). The seat (102) includes a bottom portion (114) configured to receive the fixation device (104) such that a socket (116) of the bottom portion (114) engages part of the fixation device (104) and prevents the fixation device (104) from passing entirely therethrough. The seat (102) further includes a side portion (112) configured to receive the stabilization device (106), a washer (108) and a cap (110). When the washer (108) and cap (110) are fully engaged with the seat (102), the fixation device (104) may be locked independent of the stabilizationdevice (106). The locking mechanism may also include a locking element for locking the stabilization device (106).
