New description: [New technology field] This creation is a kind of spinal fusion device' and is made of carbon fiber reinforced polydiether ketone developed in recent years. 'This creation can also be combined with biocompatible metal. Or a polymer material; wherein the metal comprises a titanium alloy, and the biocompatible polymer comprises polydithione. [Prior Art] The traditional spinal fusion device is mostly made of metal. Because the elastic modulus of the material is much higher than that of the hard bone of the vertebral body, the problem of subsidence of the fusion device is not only caused by the spinal fusion device. Height, and thus affecting bone fusion rate. In addition, although the imaging of the gold-like vertebra fusion device under the clinical development equipment is relatively clear, it is difficult for the clinician to discriminate the bone growth, which causes confusion and inconvenience in diagnosis. [New content] In order to improve the deficiency and deficiency of the prior art, the artificial spinal fusion device is made of carbon fiber reinforced poly- _ _, in addition to the nature of the material itself is more suitable for the human body than the metal ridge fusion device, appearance The design considerations are in line with the circular shape of the human vertebral body and the convenience of considering the implanted spinal fusion device and the reduction of tissue damage during the operation. The curved curved towel is designed to be used in the forest type, and the top and bottom end faces are three-dimensional. _Transfer the ridge of the coffee _ _ combined "quote between the upper and lower adjacent vertebral body fixation, turn _ red from the bone tissue. 3 M411920 In addition, the perforation design of the posterior wall can increase the blood perfusion of bone tissue in the body to enhance the fusion rate. In addition, the creation of the spinal fusion device - the side locking hole and the buckle design, the New York age device implanted a stable fixed spinal fusion device, to facilitate the operator to operate the spinal canal device implantation, fine adjustment, pull back With the take out. [Embodiment] The following examples are merely illustrative of the best mode of the present invention and are not intended to limit the scope of the present invention. Those who have knowledge of the material industry can use the disclosure of this creation to make appropriate changes and amendments in violation of the spirit of this creation. The specific embodiment of the present spinal fusion device is as shown in the figure i, wherein the spinal fusion device 10 comprises a body 1 being a curved-to-air penetration body, a front end surface and a bottom end surface of the front wall and the rear wall of the body U. The dirty end Φ ' formed by the arrangement of a plurality of triangular bodies can increase the __ force of the spinal fusion device and the upper and lower vertebral bodies after the spinal fusion device 4 1Q implants the human spine. The body u is curved and the upper middle through body forms a filling space 12, and the filling (four) 12 front wall and the rear wall are respectively provided with two circular perforations 13; in addition, the body u is interesting to lock the hole 14 Penetrating the body 11 - side wall and having a perforated structure; a pair of buckles 15 are provided on both sides of the secret hole M » The spinal fusion device 10 has a curved shape and a filling space 12 formed by the hollow through body, so After the spinal fusion device 1 () is filled with autologous bone or artificial bone tissue and 4 M411920 is implanted into the space of the affected part of the spine, the zigzag end face formed by the arrangement of a plurality of triangular bodies of the top end surface and the bottom end surface and the upper and lower adjacent vertebrae The increase in body contact area and stability can effectively promote bone fusion and achieve the early expected repair effect. The creation of the spine fusion device 10 is made of carbon fiber reinforced polydiether ketone, and can also be combined with various ages, such as metal or polymer, and the metal contains titanium alloy, biocompatible polymer. Containing polydiether ketone, the above materials are applied to the spinal fusion device 10 of the present invention with sufficient support. The inner and outer concave portions of the spinal fusion device 10 of the present invention are both arc-shaped to reduce stress concentration; in addition, the front wall and the rear wall of the filling space 12 are respectively provided with two circular perforations 13 without affecting the spinal fusion device. In the case of a supporting force of 10, it can increase the blood perfusion amount in the autologous bone or artificial bone tissue filled in the spinal fusion device 1G to increase the bone fusion probability; in addition, the body u is locked on one side wall The hole 14 is a threaded perforation structure penetrating through a side wall of the body u, and a pair of buckle portions 15 are disposed on both sides of the locking hole 14, wherein the locking hole 14 and the buckle portion 15 are provided for the body 11 Hold for the operator to perform implantation, fine adjustment, pullback or removal of the spinal fusion device 10. [Simple description of the drawing] Fig. 1 is a schematic diagram of a specific embodiment of the spinal fusion device of the present invention. 5 M411920 [Description of main component symbols] 10 Spinal fusion device 11 Body 12 Filling space 13 Perforation 14 Locking hole 15 Buckle
