Abstract

一种用于组织修复的缝合锚固件,其具有近端区段和主区段,其中近端区段和主区段由不同的材料形成。仅近端区段由诸如人体皮质骨的生物材料形成。近端区段占锚固件本体的约三分之一。

Description

具有生物近端端部的缝合锚固件
技术领域
本发明涉及一种用于将缝合线锚固到骨骼中的缝合锚固件。
背景技术
当软组织从骨骼撕下时,重新附着变得必要。各种装置,包括单独缝合线、螺钉、肘钉、楔形件和栓塞已用于将软组织固定到骨骼。为此目的,已经开发了各种类型的螺纹缝合锚固件。然而,需要一种缝合锚固件,当其安装在骨骼孔中时,其具有改善的接合性和拉出强度。
发明内容
因此,本发明提供了一种用于组织修复的缝线锚固件,其具有空心锚固件本体,该空心锚固件本体具有近端端部和远端端部以及介于近端端部和远端端部之间的插入长度。空心锚固件本体包括近端区段和主区段。近端区段远离远端端部并且终止于空心锚固件本体的近端端部处,而主区段终止于空心锚固件本体的远端端部处。近端区段和主区段由不同的材料形成。优选地,近端区段由生物材料,诸如人体皮质骨形成。
在一些实施例中,近端区段仅为空心锚固件本体的插入长度的大约三分之一;主区段由生物相容性材料形成,诸如生物可吸收材料、生物复合材料、PLLA或非吸收性PEEK。主区段包括靠近远端端部的向内渐细部分;空心锚固件本体具有向外延伸螺纹;和/或空心锚固件本体包括适于接收插入件的内孔。
近端端部优选地被构造为与插入件配连,并且远端端部被构造为与植入物协作以用于锚固缝合。
附图说明

图2是图1所示的缝合锚固件的透视图;
图3A是图1所示的缝合锚固件的侧视图;
图3B是图3A所示的缝合锚固件的侧视横截面图;
图4是图1所示的缝合锚固件的视图,示出了插入骨孔中的缝合锚固件;和
图5是类似于图4的缝合锚固件的视图,示出了安装在骨孔中的缝合锚固件。
具体实施方式
参照附图,本发明总体上涉及一种缝合锚固件100,该缝合锚固件100可以具有由人体皮质骨形成的部分以最大程度地获得骨孔和拉出强度。图1示出了根据本发明的示例性实施例的缝合锚固件100,该缝合锚固件100被接收在驱动器或插入器装置10上,该驱动器或插入器装置10具有协作植入物12以用于插入骨孔90(图4)中以进行缝合锚固。
缝合锚固件100通常包括空心锚固件本体102,其具有用于接收插入器装置10的内孔104以及外部骨骼夹持构件,诸如螺纹106,在优选实施例中,类似于在美国共有专利第8,663,279号中公开的缝合锚固件。但是,本发明可以结合在任何缝合锚固件中。
锚固件本体102具有被构造为与插入器装置10(图1和图4)配连的近端端部110以及相反的远端端部112,该远端端部112是锚固件100的首先被插入骨孔90(图4)中以安装锚固件100的端部。如图3A所示,锚固件本体102具有限定在近端端部110与远端端部112之间的插入长度L。锚固件本体102优选地具有两个区段,近端区段120和主区段122,其中区段120和122由彼此不同的材料形成,如图3B所示。
近端区段120远离锚固件本体102的远端端部112并终止于在近端端部110处。主区段122终止于在远端端部112处。在优选实施例中,近端区段120仅占据锚固件本体102的约三分之一,即近端区段120的长度仅为本体的插入长度L的约三分之一。近端区段120由诸如人体皮质骨的生物材料形成以当插入骨孔时有助于锚固件的骨整合并为覆接区(footprint)提供增加的接触面积以治愈伤口。在优选实施例中,仅近端区段120由人体皮质骨形成。
主区段122可由除人体皮质骨以外的任何生物相容性材料形成,诸如生物可吸收材料、生物复合材料、PLLA和不可吸收性PEEK或钛材料。锚固件本体102的主区段122的主要直径可以大致恒定,但是可以具有锥形部分124,该锥形部分124通常向内渐细至锚固件本体102的远端端部112处的狭窄端,如图3A和图3B最佳所示,以有助于于插入骨孔90中。骨孔90可以被预先钻孔并被预切割以接收锚固件100。可替代地,锚固件100,特别是远端端部112和主区段122可以是自穿孔的和/或自攻的。因为锚固件本体102通常是圆柱形的,所以插入器10将锚固件本体102的近端区段120和主区段保持在一起,使得它们利用对准的螺距彼此抵靠,使得两个区段120和122可以彼此相邻得被驱动至骨孔中。
如图4和5所示,锚固件100,并且特别是锚固件本体102的远端端部112,与植入物12协作以与类似于美国专利8,663,279中所述的方式将缝合线16锚固在骨孔90中。如图4所示,首先使用插入器10将植入物12(支撑缝合线16)安装到骨孔90中。然后,可以通过插入器10和/或其相关联的驱动器将缝合锚固件100驱动到骨孔90中,直到锚固件本体102的远端端部112与植入物12配接为止,如图5所示。如此,插入器10保持锚固件本体102的近端区段120和主区段122,使得它们以其对准的螺距彼此抵靠,从而使两个区段120和122可以彼此相邻得被驱动到骨孔中。锚固件本体102的近端区段120与骨孔90的肱骨皮质骨层92接合。由于锚固件的近端区段120由诸如人体皮质骨的生物材料形成,因此锚固件100与锚固件100之间的接合由于皮质骨层92和锚固件的近端区段120之间的骨整合而得以改善。诸如皮质骨的生物材料可以有利地芯吸患者的骨髓元素,并且也可以浸泡作为生物传递装置。这些特征和优点继而提高了锚固件100的拉出强度。
应该理解的是,以上使用的术语例如“侧向”,“中间”,“远端”,“近端”,“上”和“下”与本领域中使用这些术语的方式一致。此外,这些术语在本文中已经用于解释的目的,并且不应被视为另外的限制。诸如“通常”,“基本上”和“约”之类的术语并非旨在成为无边界的术语,并且应当与本领域技术人员将解释这些术语的方式相一致地进行解释。
尽管不同的实例具有图示中所示的特定组件,但是本公开的实施例不限于那些特定的组合。可以将一个实例中的某些组件或特征与另一实例的特征或组件结合使用。
本领域普通技术人员将理解,上述实施例是示例性而非限制性的。也就是说,本公开的修改将落入权利要求的范围内。因此,应研究所附权利要求以确定其真实范围和内容。
