[0026] 所述第一本体部3的一侧设有数个第一凸部12及与第一凸部12间隔设置的数个第一凹部13,所述第一本体部3的另一侧设有数个第二凸部14及与第二凸部14间隔设置的数个第二凹部15,所述数个第一凸部12与数个第二凸部14相对于第一本体部3的纵轴线相对称,所述数个第一凹部13与数个第二凹部15相对于第一本体部3的纵轴线相对称,所述第一本体部满足: [0026] side of the first body portion 3 is provided with a plurality of first recessed portions 12 a plurality of first convex portions and the first convex portion 12 spaced 13, disposed on the other side of the first body portion 3 several second recess of the second plurality of convex portions and the second convex portions 14 and 14 spaced 15, the plurality of first convex portions 12 and a plurality of second projections 14 to the longitudinal portion of the first body portion 3 relative to said axis, said first plurality of recesses 13 and a plurality of second recessed portions 15 with respect to the longitudinal axis of the first body portion opposite said 3, the first body portion satisfies:

关系式I:f=a+b; Relationship of formula I: f = a + b;

关系式2:a=b; Relationship of formula 2: a = b;

其中,f:第一凹部13与第二凹部15之间的距离,第一凹部13与第二凹部15相对称;a:第一凸部12离最近螺纹孔的距离;b:与第一凸部12相对称的第二凸部14离最近螺纹孔的距离。 Wherein, f: a first recessed portion 13 and the distance 15 between the second recess, the first recess portion 13 and the second portion 15 opposite said recess; a: the first convex portion 12 nearest from the threaded hole; b: a first protrusion the second portion 12 of said projecting portion opposite from the nearest 14 threaded hole. 在手术过程中,由于每个人的骨骼大小均存在一定差异,因此一块固定结构的钢板不可能适合所有人,因此需要钢板具有重建性,也就是说,当钢板安装于人体后,还需要根据每个人具体的骨骼形状来对钢板进行折弯微调,本发明中第一本体部3两侧凸部与凹部的设计相比于现有技术中的两侧直线设计,其折弯角度更加容易掌控,医生操作起来更加方便,大大提高了钢板的重建性能,另外通过凸部与凹部的尺寸设计满足一定的关系式,可以避免应力集中。 During the surgery, since the size of each human skeletons were some differences, so a plate fixing structure is not possible for everyone, it is necessary to rebuild the steel sheet having resistance, that is, when the plate is attached to the body, but also according to each of specific individual skeletal shape of the steel sheet bending trimming, the present invention is designed on both sides of the first body portion and the concave portion 3 projecting portion compared to the prior art linear designs on both sides, which is easier to control the bending angle, physician more convenient to operate, greatly improving the performance of the reconstruction plate, and the other by the convex portion and the concave portion size is designed to satisfy a certain relationship, the stress concentration can be avoided.

[0027] 综上所述,本发明中的腓骨远端锁定钢板通过在螺纹孔内设置数个沿螺纹孔轴向延伸的切口,从而将螺纹孔的孔壁分成数段,手术时,医生可根据骨折线的具体位置来选择固定螺钉的拧入角度,本发明中的螺纹孔结构可以满足固定螺钉的多方向拧入需求,当固定螺钉拧入螺纹孔内时,无论拧向哪个方向,总有一段孔壁的内螺纹与固定螺钉的外螺纹相旋合,其余几段孔壁对固定螺钉进行挤压,从而实现多方向锁定。 [0027] In summary, the distal fibula locking plate in the present invention by providing a plurality of cutouts along the threaded holes in the axially extending threaded hole, so that the threaded bore hole wall into several segments, surgery, the physician can the specific location of the fracture line to select the angle of fixing screws screwed into the threaded hole in the structure of the present invention meet the requirements of direction of the fixing screws screwed into demand, when the fixing screw is screwed into the threaded hole, no matter which direction to twist, total internally threaded bore wall section with an external thread screwed together with fixing screws, the remaining paragraphs of hole wall fixing screw extrusion, in order to achieve multi-directional lock.

[0028] 上述实施例只为说明本发明的技术构思及特点,其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施,并不能以此限制本发明的保护范围,凡根据本发明精神实质所作的等效变化或修饰,都应涵盖在本发明的保护范围内。 [0028] Examples of the above-described embodiments illustrate the technical concept and features of the invention, its object is to only allow those familiar with the art to understand the present invention and implement them, and thus does not limit the scope of the present invention, where an equivalent variations or modifications made from the spirit of the present invention, shall fall within the protection scope of the present invention.
