[0047] 需要说明的是,实施例1-5任一所述的本发明的髌骨骨折可加压针缆固定系统的各组件材质为钛合金或不锈钢。 [0047] Incidentally, the patella first embodiment of the present invention the fracture of any of claims 1-5 pressurizable material components pin cable fixing system is a titanium alloy or stainless steel. 实施例3-5任一所述的垫圈5也可选择爪型垫圈,请参照附图14和15,附图14是爪型垫圈的结构示意图,附图15是爪型垫圈的主视图,采用爪型垫圈的优点是除普通垫圈的作用外可对骨折块具有更好的把持作用。 Example 5 a gasket according to any one of embodiments 3-5 Alternatively claw washer, 14 and 15 refer to the drawings, FIG. 14 is a schematic view of the pawl washer, Figure 15 is a front view of a claw-type gasket used claw washer advantage is better gripping action on the fracture fragments in addition to the role of ordinary washer. 所述的爪型垫圈呈四爪型,中心有一中心孔,中心孔直径为爪型垫圈的爪间距分别为2-10mm和10-20mm,使用时四爪面朝向骨折的髌骨。 The four claw washer as a jaw, has a central hole, the center hole diameter of the jaw spacing pawl washer 2-10mm and 10-20mm, respectively, for a four-jaw surface facing when patellar fracture. 实施例1-5任一所述的针缆固定系统可以作为医疗器械在治疗髌骨骨折、尺骨鹰嘴骨折、桡骨远端骨折、尺骨远端骨折、踝关节骨折、距骨骨折、骶骨骨折、骨盆骨折中应用。 Example needle cable fixing system according to any of embodiment 1-5 may be the treatment of patellar fracture as a medical device, olecranon fractures, fractures of the distal radius, ulna fracture, ankle fracture, talus fractures, fractures sacrum, pelvic fractures application.

[0048] 本发明与目前市场上销售的普通空心加压螺钉或钉缆相比,不但安装简单,而且 [0048] Compared with the ordinary hollow currently marketed compression screw or nail cable, not only easy to install, and

6安装过程中可以达到骨折断端加压的目的,而且在张力带固定时可因针缆滑动使得针缆各个部分的压力得到均衡,形成整体加压的效果;由于本系统无螺纹样等尖锐结构不会产生植入物间的切割,且针缆的可滑动性使得行钢缆张力带固定加压时各部分的压力得到均匀分散,降低了植入物断裂的风险。 6 the installation process can achieve the purpose of pressurizing the fracture fragments, and when the tension band can slide so that the pressure due to the respective cable needle of the needle to give a balanced cable, integral pressurizing effect; unthreaded Since the system like other sharp cleavage does not occur between the structure of the implant, and the needle so that the slidability of the cable line cable tension with the pressure of various portions when fixed pressing to obtain a uniform dispersion, the implant reduces the risk of breakage.

[0049] 以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员,在不脱离本发明方法的前提下,还可以做出若干改进和补充,这些改进和补充也应视为本发明的保护范围。 [0049] The above are only preferred embodiments of the present invention, it should be noted that for those of ordinary skill in the art, without departing from the method of the present invention, can make various improvements and additions, modifications and additions of these also it is considered the scope of the present invention.
