After the convex end portion 201 of the sleeve 200 is placed in the curved surface concave portion 111, the sleeve 200 is rotated to allow the convex portion 202 to enter the groove 114 to prevent the sleeve 200 from falling off (Fig. 6) Then, the thread 301 is screwed with the thread 118 provided in the through hole 113. . At this point, the spine implant structure 100, the set 2〇〇 and the implant rod 300 of the present invention can be stably combined into one unit. Next, the operator can place the spinal implant structure 1 into the spine of the patient by holding the aforementioned grip portion 303'. Further, since the end of the spinal implant structure 1 〇〇 which is in contact with the patient first is set as the aforementioned rounded corner 112', the resistance when placed in the patient's tissue is reduced. The opening structure (10) opened by the interbody fusion between the mouth and the upper hole is the same as the implanted rod _ the aforementioned spine plant 1 (9) is still maintained one; the spinal implant structure adjusts the aforementioned spinal implant (1) Carcass: 2 „Adjustment. To describe the angle of the grip 303〇', the operator can rotate the first two! 乂: The implant rod 300 is loosened from the thread, the 118, and the 301 # screwing relationship. It should be noted that the aforementioned implant 300 should be maintained from the aforementioned spine implant structure 1 'the need to maintain the above-mentioned sleeve / degree ^ ^ month (J said convex portion 202 is stuck in the aforementioned groove U4 (such as The six sleeves are shown as 'avoiding the aforementioned sleeve 200 from falling out of the aforementioned spinal implant structure 1'. Then 'applying force from the end of the sleeve 200, more specifically, applying force downward from the end, The displacement of the sleeve 200 and the spine implant structure 100 by the urging force is displaced by the engagement of the curved surface of the convex end portion 201 of the sleeve 200 with the curved surface of the curved concave portion, and the sleeve 200 The convex portion 202 provided on the outer wall is engaged in the groove 114 to make the sleeve The angle between the ridge and the spinal implant structure 1 渐 is gradually changed along with the sliding of the convex portion 202 in the aforementioned groove 114. Accordingly, the aforementioned spinal implant structure can be gradually changed. 100 is the angle in the patient's spine. It is worth noting that 'the aforementioned sleeve 200 can be used as a user to urge the aforementioned spinal implant structure because the aforementioned convex portion 202 is locked and slid in the aforementioned groove 114. The medium of the angle change 100 is not detached from the spine implant structure 100. Thus, it can be understood that, in order to facilitate the sliding of the convex portion 202 in the M422953 groove Π4, the groove 114 is configured to have The curvature is matched with the curved surface of the convex end portion 201 and the curved surface of the curved concave portion 111. Preferably, the curvature and the curved surface of the convex end portion 201 are concentric arcs; more specifically, the foregoing The curvature of the groove 114 and the curved surface of the convex end portion 201 have the same spherical center in geometric design, and the radius of the arc relative to the spherical center is opposite to the curved surface of the convex end portion 201. The radius of the core is increased. Accordingly, when the curved surface of the convex end portion 201 and the curved surface of the curved concave portion 111 are pivoted to each other, the convex portion 202 can smoothly follow the curvature of the groove 114 and slide therein. If the groove 114 is set to a straight line, the effect may be slightly worse than that of the embodiment, or it is more difficult to implement, but still conforms to the spirit of the creation. Please refer to the seventh figure, to be adjusted. After the spine is implanted into the structure 100 to a desired angle, the sleeve 200 (as indicated by the arrow in the figure) can be appropriately rotated to disengage the convex portion 202 from the groove 114, thereby facilitating The aforementioned sleeve 200 is removed from the aforementioned spinal implant structure 100. Finally, please refer to the eighth figure, and the actuating relationship between the convex end portion 201 and the curved concave portion 111 will be further explained through the enlarged drawing. As can be seen from the figure, the convex end portion 201 and the curved surface concave portion 111 which are set as the corresponding curved surfaces can slide each other like a cymbal and a cymbal. Since the convex portion 202 and the groove 114 are mutually engaged, the sliding direction of the convex end portion 201 and the curved concave portion 111 is restricted. Accordingly, when the sleeve 200 is stressed, the convex end portion 201 slides in a single direction of the curved concave portion 111 to push the angle of the spinal implant structure 100 in the patient tissue until the operator desires . In addition, it is noted that the opening inner diameter 119 of the curved surface concave portion 111 is not smaller than the maximum outer diameter 11 M422953 204 of the convex end portion 201; preferably, the opening inner diameter 119 is approximately equivalent to the convex end portion. The maximum outer diameter 204 of 201 will facilitate the action of the convex end portion 201 in the curved surface recess 111 described above.
