[0018]下面结合附图说明和实施例对本发明作进一步说明,本发明的方式包括但不仅限于以下实施例。 [0018] The following description and the drawings of the embodiments of the present invention will be further described in conjunction with the present invention include, but are not limited to the following examples.

[0019] 实施例1 [0019] Example 1

[0020]如图1所示,本发明提供了一种腰椎峡部修补装置,其包括第一 U型固定装置1、连接棒以及连接机构。 [0020] As shown in FIG 1, the present invention provides a prosthetic device Lumbar portion, which comprises a 1, and a connecting rod connecting a first U-shaped fixture mechanism. 所述连接棒包括圆柱直段2和扁平抛物线段3,其中,圆柱直段为4〜6_的直径圆棒,而扁平抛物线3采用扁平状设计,可实现转角处的增强,从而避免内固定时发生断裂。 The connecting rod comprises a straight cylindrical section 2 and the flat parabolic segment 3, wherein a cylindrical rod having a diameter 4~6_ straight section, and 3 use flat flat parabola designed to achieve enhanced at the corners, thereby avoiding the implant when broken. 所述的圆柱直段2—端固定在第一U型固定装置I 一侧,另一端与扁平抛物线段3的一端连接。 The cylindrical straight section on one side of a first end secured 2- U-shaped fixing device I, the other end of the parabolic section 3 is connected with the flat end.

[0021]所述的连接机构则连接在扁平抛物线段3的另一端。 [0021] The connecting means is connected to the other end of the flat parabolic segment 3. 如图2、3所示,本实施例中,所述的连接机构包括与扁平抛物线段3连接、且中部开设有螺孔5的第一垫块4(厚度为2〜3mm,宽度为6〜8mm),均布在第一垫块4一侧面四周边缘的第一尖钉6,以及第二垫块7;所述第二垫块7中部开设有位置与螺孔重叠的通孔8,且该第二垫块7—侧面中部的四周均布有第二尖钉9;所述第一垫块4和第二垫块7紧贴棘突的表面形状均与棘突生理形状相匹配(如图1所示)。 2 and 3, in this embodiment, the connecting means comprises a connecting flat 3 and parabolic segment, and the central spacer defines a first screw hole 4, 5 (a thickness of 2~3mm, a width of 6 ~ 8mm), uniformly distributed in a first side peripheral edges of the pad 4 first spike 6, 7 and the second block; the second spacer 7 has a central through hole defines a position overlapping the screw hole 8, and 7- the second block side are evenly distributed four weeks a second central spike 9; the first block 4 and the second block 7 against the surface shape of the spinous processes are matched to the shape of the spinous processes physiological (e.g. As shown in FIG. 1). 本实施例中,第二垫块7用于与第一垫块配合实现对棘突固定,具体做法是:将第一垫块4和第二垫块7分别放在棘突的两侧,并使两个垫块中的通孔与螺孔对齐,然后利用垫块上的尖钉钉入至棘突中,最后利用固定螺钉经由通孔打入螺孔中,即可实现对棘突的锁紧和固定。 In this embodiment, the second spacer 7 for mating with the first block to achieve a fixed spinous process, would be: the first block 4 and the second block 7 are placed on both sides of the spinous process, and in that the two spacers are aligned with the screw through-holes, and then using the tip of the nail into the spacer to the spinous process, and finally the locking screws through the through hole into the screw hole, locking can be achieved on the spinous tight and fixed. 本实施例中的尖钉平均长度约I〜1.5mm,其在锁紧棘突的过程中可以钉入棘突,并且第一尖钉和第二尖钉的位置设计方式可以避免在钉入棘突或者旋转90°时两边的尖钉交叉对撞,导致垫块对棘突固定不稳。 The average length of the spike about I~1.5mm embodiment of the present embodiment, it may be driven into the spinous process of locking the spinous processes, and the first spike and the second position of the spike design in a manner to avoid the driving ratchet projections or rotated 90 ° on both sides of the spike cross collision, resulting in fixing the spinous process spacer of instability.

[0022]本实施例在使用时,将第一 U型固定装置I固定在椎弓根内,然后将连接棒置入第一U型固定装置I中并进行压紧固定。 [0022] In use of this embodiment, the first U-shaped fixing means I secured within the pedicle, and then into a first U-shaped connecting bar fixing means I, and pressed and fixed. 而后,将第一垫块4和第二垫块7横向固定在棘突两侧,并对齐,最后再将固定螺钉经由通孔打入螺孔中即可。 Then, the first block 4 and the second block 7 fixed transversely on both sides of the spinous process, and aligned, then the final fixing screws into screw holes through the through hole can. 本实施例可以设置与第一U型固定装置和连接棒相同的结构,用于支撑和固定第二垫块的位置,以使其与第一垫块完美配合,并紧贴棘突,同时第一尖钉和第二尖钉不会发生交叉对撞,如此可以很好地实现对棘突的稳定及固定,如图1所示。 The present embodiment may be provided with a first U-shaped structure fixing apparatus and the same connecting rod, for supporting and fixing the position of the second pad, so as to perfectly mate with the first block, and close to the spinous processes, while the first a spike and the spike does not occur a second cross-collision, thus can realize stable and fixed to the spinous processes, as shown in FIG.

[0023] 实施例2 [0023] Example 2

[0024]如图4所示,与实施例1的不同点在于,所述连接机构包括与扁平抛物线段3连接的第二U型固定装置10,以及贯穿第二U型固定装置并横向打入棘突下方的钉钩(即双钉钩系统,下边钉钩可以为传统的钩)。 [0024] As shown in FIG 4, it differs from Embodiment 1 in that, said second connecting means comprises a U-shaped fixing means 10 is connected to the flat parabolic section 3, and a second U-shaped fixing means penetrating transversely into and below the spinous process hooks nail (i.e. nails double hook system, it may be a conventional hook staple lower hooks). 本实施例主要适用于棘突发育缺陷、不能在棘突一侧打钉固定的情况。 This embodiment is mainly applied to the spinous processes of developmental defects, can not play in the case of a fixed stapling spinous process side.

[0025]本发明结构看似简单,实则不易想到,其通过巧妙的设计,使得设计出来的腰椎部修补装置可以很好地适用于腰椎峡部裂修复手术,从而有利于植骨及植骨后的良好愈合。 [0025] The structure of the present invention appears to be simple, but in reality is not easy to think of, by clever design, so the lumbar portion of the prosthetic device designed well suited for spondylolysis repair surgery, and bone graft to facilitate the good healing. 因此,与现有技术相比,本发明具有突出的实质性特点和显著的进步。 Thus, compared with the prior art, the present invention has prominent substantive features and represents a notable progress.

[0026]上述实施例仅为本发明的优选实施方式之一,不应当用于限制本发明的保护范围,凡在本发明的主体设计思想和精神上作出的毫无实质意义的改动或润色,其所解决的技术问题仍然与本发明一致的,均应当包含在本发明的保护范围之内。 [0026] The embodiment described above is only one preferred embodiment of the present invention and should not be used to limit the scope of the present invention, where there is no real meaning in the body design and spirit of the present invention are made by alteration or polish, they solve the technical problem remains consistent with the present invention are intended to be included within the scope of the present invention.
