                        技术领域Technical field

本发明是有关一种脊椎固定器，特别是有关一种可调整角度的脊椎固定器。The invention relates to a spinal fixer, in particular to an angle-adjustable spinal fixer.

                        背景技术 Background technique

传统脊椎固定器(例如参见图1)无法调整角度，不能适用为不同脊椎骨节间的脊椎固定器，若勉强使用，将使待固定的脊椎骨节于固定后的相对位置改变，造成不当的脊椎固定。The traditional spinal fixator (see Figure 1 for example) cannot adjust the angle and cannot be used as a spinal fixator between different vertebral joints. If it is used reluctantly, the relative position of the spinal joints to be fixed will change after fixation, resulting in improper spinal fixation .
