Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] Referring to Fig. 1, it is a schematic structural view of an embodiment of the fixing plate of the present invention. The middle position of the fixing plate 1 is a rectangular preset bone groove 4 with a cross section integral with the fixing plate 1, and the rectangular preset bone groove 4 is provided for Implanted with autologous or allogeneic bone or other artificial bone, the rectangular preset bone groove 4 protrudes from the bottom of the plate, as shown in Figure 2, after the rectangular preset bone groove 4 is implanted into autologous or allogeneic bone or artificial bone and connected with the vertebral body, it can Form bony connection with the user's vertebral body, that is, the preset bone groove 4 has a surface induction effect of inducing osteogenesis or guiding bone regeneration. The preset bone groove 4 can be any geome...

Abstract

One kind of lordosis biological induction osteogenesis inner fixing apparatus comprises dead plate and dead hole set on plate. The bottom of dead plate mentioned also set a presetting bone plot extruded to dead plate at least for embedding self, heterogenous or other artificial bone; circumference of dead plate distributes equably four or more dead holes; dead holes are angling hole, positive going screwed hole, leaning screwed hole, T-type hole or reverse ladder type hole; the longitudinal radian of dead plate is similar to physiological bending angular of vertebra; when operating, putting embedding self, heterogenous or other artificial bone in presetting bone plot, using effect of interface induction of dead plate or bone induction, joining quasi-fixed adjacent two or more centrums and forming bony link, assisting fusion of embedded bone between centrums, and achieving better effect.

Description

technical field [0001] The invention relates to a medical device, in particular to an intervertebral fixation plate for anterior spinal approach and related special devices, belonging to the field of medical devices. Background technique [0002] Surgical treatment of spinal disorders has been widely used, and intervertebral fusion technology has achieved better results due to the advancement of internal fixation devices, but there are still some defects in internal fixation devices, resulting in unsatisfactory intervertebral fusion. For example: at present, the success rate of cervical intervertebral fusion is up to 95% in a single segment, but can only reach 75% in multi-segment. The existing intervertebral fusion method is to form a bony connection between the vertebral bodies by means of an anterior fixation plate and / or an intervertebral cage and / or a titanium cage. , still can not achieve a 100% fusion rate. Contents of the invention [0003] The present invention ...
