Description

骨钉
技术领域
本发明涉及一种骨钉，其具有：螺杆，所述螺杆具有尖端并且同心于螺钉纵轴线，并且所述螺杆锚固到骨或骨部分中；固定在所述螺杆上且具有接合机构的螺钉头。
背景技术
长期以来已知这种类型的骨钉。所述骨钉例如用于骨缝术的骨固定。在这种情况下，这样的螺钉特别是用于将板或连接杆锚固在脊柱上。在这种情况下，所述螺钉主要承受应力，例如通过在所述螺钉和连接杆之间的夹紧连接或者与板的夹紧连接。例如从US 5,466,237中已知这种类型的骨钉。所述骨钉用于将连接杆固定在脊柱上。在这种情况下，所述连接杆夹紧在螺钉头和螺母之间。
EP 0 507 162 A公开了一种骨钉，所述骨钉用于将骨板固定在脊柱上。所述骨钉借助于套筒保持在骨板中。
EP 1 191 891 A公开了一种骨钉，所述骨钉具有轴向两段式螺钉头。因此使螺丝刀更容易插入螺钉头中。
已提及的骨钉由金属，特别是钛制成。所述金属具有高的强度，以至于所述金属在拧入时和在与植入物连接的情况下可承受高负荷。但是，在这里不利的是缺少X射线穿透性。
发明内容
本发明的目的在于，提供一种所述类型的骨钉，所述骨钉更多地或至少局部地是X射线可穿透的，但是所述骨钉仍然是性能可靠的。
在此种类型的骨钉中所述目的如下得以实现，即通过所述螺杆基本上由X射线可穿透的塑料制成，并且至少一个承载区域具有一部分，其中，所述部分由与芯体的基本上形成所述螺杆的材料不同的材料制成。根据本发明的骨钉的X射线穿透性通过由X射线可穿透的塑料，例如聚醚醚酮(PEEK)或纤维增强的PEEK制造螺杆来获得。纤维增强的PEEK和PEEK是X射线可穿透的，并且具有相对高的强度。但是，纤维增强的PEEK同时是相对脆的。尽管这个脆性，但是由纤维增强的PEEK制成的螺杆是可能的，因为至少一个承载区域具有由另一种材料制成的部分。所述材料是金属或PEEK。所述部分优选设置在螺钉头上，并且具有已提及的接合机构。如果所述部分由金属制成，那么所述骨钉仅在所述螺钉头的区域中不是X射线可穿透的。如在通常的由钛制成的螺钉中，这样的螺钉可以在螺钉头上例如借助于螺丝刀拧入，并且夹紧。承载区域为特别是承受应力的区域，如尤其是螺钉头和/或所述螺钉尖端。
根据本发明的改进形式提出，所述部分设置在所述螺杆的尖端上。这个部分特别是设有螺纹，并且可实现高的钻孔特性或螺纹切削特性。此外，所述钻头尖端可构成为是自攻的。尽管如此，根据本发明的骨钉在所述螺杆的区域中是在一定程度上X射线可穿透的。
根据本发明的改进形式，所述部分构成套筒形。这样的套筒形部分例如可通过压配合或通过粘接与所述螺杆连接。根据本发明的改进形式，设有所述套筒，以改善剪切强度。所述套筒优选设置在螺杆的位于所述螺钉头和所述尖端之间的中央区域中。
所述部分优选设置在所述螺钉头上。但是也可设想一种实施形式，在所述实施形式中，在螺钉头上设置有第一部分，并且在螺杆的尖端上设置有第二部分。一方面，因此获得非常好的钻孔特性和螺纹切削特性，并且另一方面，获得骨钉在所述螺钉头上的高的承载能力。在这种情况下，所述螺杆也是在一定程度上X射线可穿透的。
