Description

V. New Description: [New Technology Area] Year 3 Correction Supplement This creation is about a tool for adjusting the position of a spinal implant structure, and a spinal implant kit containing the aforementioned tools. [Prior Art] The spinal implant structural system is used in the bone fusion surgery to replace the artificial implant of the diseased intervertebral disc to provide support and enhance the stability of the spine, and the spinal implant can be filled with autologous bone or Artificial bone tissue 'to promote the effect of bone fusion. . Traditional spinal implant structures need to be fixed with metal steel nails and steel plates or steel rods from the front or the rear to average the stress load and reduce the implant β and lower to the cancellous bone (cance丨丨〇us b 〇ne) in order to avoid compressing nerve tissue. In recent years, a convex-toothed structure has been added to the spine-implanted structure to improve the stability of the implant between the vertebrae. As shown in the first figure, it is composed of two hollow through-body (1). Simple combination. The current spinal implant structures are mostly made of metal (such as titanium alloy) and polyetheretherketone (PEEK). However, the hardness of the metal material is high, and it is easy to fall into the vertebrae after implantation. The Young's modulus of PEEK It is low and is easily damaged by long-term stress caused by torque and flexion. Therefore, in recent years, there has been a gradual change in the choice of implant materials, such as carbon fiber reinforced polyetheretherketone (CFR-PEEK), which uses hardness close to cortical bones (corticaib〇ne). In addition, the existing spinal implant structure is not easy to adjust after implantation, and if the position is deviated during the surgical implantation, it is not easy to pull back or take out, which is easy to cause injury and medical treatment. 3 M409825

One end of the rod body 421 near the grip portion 422 is provided with a thread 425 that engages with the thread 322. Referring to FIG. 11 again, in the illustrated embodiment, after the implant rod 420 is placed in the sleeve 32, the thread 322 and the thread 425 can be screwed together to make the implant rod 42〇 is combined with the aforementioned sleeve 320. Wherein, the tapered structure 423 of the implant rod 42A protrudes from the end of the protrusion structure 321 provided by the sleeve 320. The eleventh figure of Fig. 1 shows an oblong adjustment hole 12A to explain the action relationship between the implant rod 41 and the aforementioned sleeve and the aforementioned adjustment hole =0. Taking the illustrated embodiment as an example, the structure 313 of the sleeve 3 is designed to be filled in the adjustment hole 12A, so that the adjustment hole 120 leaves a circular through hole 122. The diameter of the aforementioned circular through hole 12 is in principle at least larger than the circumference of one of the aforementioned tapered structures 413. M409825

The diameter is at least less than the circumference of the tapered structure 413. In the embodiment, the diameter of the circular through hole 122 is substantially equal to the maximum circumferential diameter 414 of the tapered structure 413. The diameter of the circular through hole 122 is slightly smaller than the maximum circumferential diameter 414 of the aforementioned tapered structure 413. Accordingly, in the embodiment of Fig. 12a, the protrusion structure 313 is a type of crescent-shaped structure for filling the adjustment hole 12A, and the adjustment hole 120 is left with the circular through hole 122. Referring to FIG. 12A' and the eighth embodiment of the present invention, the spinal implant structure 110 of the first figure of the present invention is taken as an example, whereby the structural configuration is continued when the grip portion 412 of the implant rod 410 is continuously rotated. When the implant rod 410 and the sleeve 310 are screwed together by the thread 312 and the thread 415, the implant rod 410 can be continuously extended into the circular through hole 122. Since the diameter of the circular through hole 122 is substantially equal to the maximum circumferential diameter 414 of the tapered structure 413, more specifically, the diameter of the circular through hole 122 is slightly smaller than the maximum circumferential diameter 414 of the tapered structure 413. Therefore, during the process in which the implant rod 41 is continuously extended, the tapered structure 413 gradually fills the circular through hole 122 until the circular through hole 122 is fastened to the tapered structure. The maximum circumferential diameter 414; according to this, the aforementioned implant rod 41〇, the aforementioned sleeve 31〇 and the aforementioned spinal implant structure 11 can be stably integrated into each other to facilitate the insertion of the aforementioned spinal implant structure. 11〇 implanted in the appropriate position. In general, the shape of the adjustment hole 12〇 and the protrusion structure 313 need not be limited, as long as the two can be filled with each other, and the adjustment hole 120 has a diameter substantially equal to the circumference of one of the tapered structures 413. The circular hole 122 can conform to the spirit of this creation.

The adjustment hole 120 is filled in such a manner that the adjustment hole 120 has a diameter substantially equal to the circular through hole 122 of the maximum circumferential diameter 414 of the tapered structure 413. In addition, it is to be noted that, since the tapered structure 413 has a diameter of at least one circumference from the largest to the smallest, the matching relationship between the adjusting hole 12 and the protruding structure 313 may also be designed to leave a circular through hole 122. The diameter of the circular through hole 122 is substantially equal to any one of the diameters of the tapered structure 413, so that the tapered structure 413 is engaged with the circular through hole 122. Similarly, the implant rod 420 and the sleeve are 32〇 and the aforementioned vertebral implant structure 210 are designed in the same spirit and have the same actuation relationship. On the other hand, as mentioned in the four sides, in still another embodiment of the implant rod 410 of the present invention (thirteenth view), the aforementioned joint portion is an extension of the rod body 411 of the aforementioned implant rod 410. And the peripheral wall of the aforementioned joint portion and the peripheral wall of the circular through hole are provided with threads 416 that are mutually screwed. It should be noted that the joint of the implant rod 41〇 in the embodiment of Fig. 12 is not a tapered structure. More specifically, in this embodiment, the inner wall of the circular through hole 122 is formed by combining the inner wall of the adjusting hole 12''''''''''''''' The inner wall of the portion of the adjustment hole 120 and the peripheral wall of the protrusion structure 313 are pre-formed with a pattern, and the pattern causes the inner wall of the circular through hole 122 to form a thread. At the same time, the peripheral wall of the joint portion of the implanting rod 41 is provided with another thread 416 that cooperates with the aforementioned thread; accordingly, rotating the implant rod 410 allows the ridge to be implanted into the structure 11 Sleeve 32. And the aforementioned implant rods are integrally integrated with each other by the above-mentioned pre-established 16 M409825 thread structure (not shown).

It can be seen from the preceding paragraph that the spirit of the present invention is to design a protruding structure on the sleeve, and the adjusting hole of the spine implant structure is filled into a circular through hole by the protruding structure, and the circular through hole and the aforementioned implant The joints of the rods can cooperate with each other to form a stable bond. On the other hand, the spirit of the present invention lies in the cooperation relationship between the circular through hole and the joint of the implant rod, and in one embodiment, it is a rigid relationship of the tapered structure; In the sample, it is the screwing relationship of the thread structure.
