Therefore, when the second contact portion 320 and the third contact portion 330 are fastened to the spacer 400, the extension part 440 may be bent toward the spinous process 3 to facilitate fastening. In addition, since the extension part 440 is made of a flexible material, the extension part 440 may be applied to various spinous processes 3 of individuals having different shapes.
- FIG. 13 is a front view showing a state in which the spinal spinous process fixing device according to another embodiment of the present invention is inserted into the body from the back
- FIG. 14 is a spinal spinal process fixing device according to another embodiment of the present invention. Is a perspective view showing a state in which is inserted into the body.
- the spacer 400 is inserted between two adjacent spinous processes 3 so that a pair of spinous processes 3 are positioned at the insertion part 410 of the spacer 400.
- the first opening hole 510 and the second contact portion 320 are spaced apart from each other.
- the spinous process member 3 is inserted into the second opening hole 520.
- the second contact portion 320 and the third contact portion 330 are positioned in the second insertion groove 430 formed on the rear surface of the spacer 400.
- the convenience of the procedure can be improved by simple fastening of the spacer 400 and the clip 300 during the procedure. Therefore, since the procedure time is shortened, both the doctor and the patient can reduce the burden of a long time line, and the time taken for the recovery of the patient can also be shortened.
