SPINAL FIXATION LOCKING MECHANISM

摘要

The present invention relates to a locking mechanism and method of fixation, such a the fixation of a fixation device (104) like a bone screw and of a stabilization device (106 like a rod to the spine. The locking mechanism (100) includes a seat (102) and a locking element (108). The seat 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 (106) further includes a side portion (112) configured to receive the stabilization device (106) and a locking element (108). The locking element (108), when fully engaged with the side portion (112) of the seat (102), causes locking of the relative positions of the fixation device (104) and the stabilization device (106).
