相关申请的交叉引用
本申请是2009年11月10日提交的美国专利申请No.61/259732的PCT国际专利申请，该申请的全部内容通过参考的方式并入本文。
技术领域
本发明涉及组织修复，更具体地，涉及用于将组织固定到骨的锚固件。
背景技术
关节镜手术经常要求将软组织重新附接到骨。为了实现此，将锚固件置于骨中，将附接于锚固件的缝合线穿过组织从而把该组织牢固地保持就位。在对骨进行软组织修复时，有利的是在骨和组织之间有尽可能大的接触面积。成行彼此间隔的锚固件点导致的修复具有较宽广的接触面积。需要这样一种手术以及在这种手术中使用的构件，该手术利用多个附接点在大的接触面积上将组织牢固地附接到骨。这种手术必须要能够迅速有效地完成，并且患者的康复时间最短。
发明内容
在一个方面，本发明涉及一种锚固组件。所述锚固组件包括：锚固件，其包括远端部分和近端部分，所述锚固件限定容腔和通向所述容腔的开口；插入部件，其设置在所述锚固件的所述容腔内；以及套管，其联接到所述锚固件，所述套管设置在所述锚固件的近端部分之上。在一个实施例中，所述锚固件的远端部分包括倒钩。在另一个实施例中，所述锚固件包括通孔。在又一个实施例中，所述容腔包括螺纹。在另一个实施例中，所述插入部件包括具有螺纹的近端部分和无螺纹的远端部分。在又一个实施例中，所述插入部件包括插管。在一个实施例中，所述套管包括具有螺纹的近端部分和无螺纹的远端部分。在另一个实施例中，所述锚固件包括突起。
在另一个方面，本发明涉及一种用于组织修复的锚固件输送装置，该装置包括：手柄；联接到所述手柄的第一旋钮；联接到所述手柄的第二旋钮；以及联接到所述手柄的轴杆，所述轴杆包括外部件、设置在所述外部件中的内部件、以及设置在所述内部件中的驱动器。在一个实施例中，所述驱动器的近端部分联接到所述第一旋钮，所述外部件的近端部分联接到所述第二旋钮。在另一个实施例中，所述锚固件输送装置还包括联接到所述外部件的套管、联接到所述内部件的锚固件、以及设置在所述锚固件的容腔中的插入部件，所述插入部件联接到所述驱动器。
以下参照附图详细描述了本发明的其它特征、方面和优点以及本发明各种实施例的结构和操作。

具体实施方式
为了最好地解释本发明的原理及其实际应用以便让本领域的其它技术人员能够最好地在各种实施例中使用本发明并让各种修改适合于所设想的具体应用，选择并描述了这些实施例。
图1-6示出了本发明的锚固组件10的各构件。组件10包括锚固件11、插入部件12和套管13。锚固件11包括远端部分11a、近端部分11b、限定在锚固件11中的容腔11c和通向容腔11c的开口11c’、具有两个开口11d’的通孔11d、位于各开口11d’下方的突起11e、以及位于远端部分11a的外表面11a’上的倒钩11f。插入部件12包括具有螺纹12a’的近端部分12a、无螺纹的远端部分12b、以及插管12c。套管13包括具有螺纹的近端部分13a、无螺纹的远端部分13b、容腔13c、以及通向容腔的开口13d。锚固件的容腔11c包括螺纹11c’’，在部件12插入到容腔11c中时，螺纹11c’’与插入部件12的螺纹12a’接合。
图7-11示出了用来与图1中锚固组件一起使用的输送装置20。装置20包括手柄21、联接到手柄21的第一旋钮22、联接到手柄21的第二旋钮23、以及联接到手柄21的轴杆24。轴杆24包括外部件24a、设置在外部件24a内的内部件24b、以及设置在内部件24b内的驱动器25。
如图8-11所示，驱动器25的近端部分25a联接到第一旋钮23，外部件24a的近端部分26a经由可动部件27联接到第二旋钮22。可动部件27包括远端部分27a、近端部分27b、以及插管27c。近端部分27b包括在其外表面27b’’上的螺纹27b’。可动部件27位于手柄21的容腔21a内。容腔21a包括远端部分21a’和近端部分21a’’。近端部分21a’’包括螺纹21b，螺纹21b与近端部分外表面27b’’上的螺纹27b’接合。如下文将进一步解释的，由于可动部件27与容腔的近端部分21a’’的螺纹接合，旋钮22的旋转使得外部件24a沿着轴杆24的长度轴向运动。当可动部件的远端部分27a的端部27a’接合容腔的远端部分21a’的端部21c时,旋钮22的旋转中止，从而防止套管13过度插入到骨中。
驱动器25的近端部分25a包括螺纹25a’，螺纹25a’与内部件24b的内表面24b’上的螺纹29接合。驱动器25与内部件24b的螺纹接合允许通过旋钮23的旋转而使驱动器25沿着轴杆24进行轴向运动。当深度止动器25b接合内部件24b的端部24b’’时，旋钮23的旋转中止，从而防止插入部件12过度插入到锚固件11中，如下文将进一步解释的。
在组织修复期间，将缝合线附接到软组织，在骨中形成孔，将缝合线的端部穿过锚固件11的通孔11d，通过输送装置20的轴向前进将锚固件11置于骨的孔中，旋转旋钮23以使插入部件12轴向运动并且接合和固定缝合线到锚固件11，然后旋转旋钮22以使套管13轴向运动并将套管13的远端13b置于锚固件11的近端11b之上，且进一步将缝合线锁定在套管13和骨之间。图12和13示出了没有缝合线的组装好的锚固组件10。在使插入部件12前进以接合缝合线之前，可将缝合线张紧。任选地，可将缝合线锚固件置于骨内，让缝合线的端部穿过软组织，然后让端部穿过锚固件11的通孔11d。修复将如上所述那样继续。在美国专利申请公开No.20090112270、No.20100016869、No.20100016902中示出并描述了类似类型的修复，这些申请的全部内容通过参考并入本文。
锚固组件的各构件由聚合物材料采用注射成型工艺制成。然而，可使用其它的材料和工艺。输送装置的手柄和旋钮由聚合物材料采用注射成型工艺制成。手柄和旋钮通过过盈配合联接。然而，可使用其它的材料、制造工艺和联接方法。轴杆的各构件由金属材料采用挤出工艺或拉延工艺制成。轴杆的各构件通过螺纹配合或过盈配合联接到手柄和旋钮。然而，可使用其它的材料、制造工艺和联接方法。
由于可以在不偏离本发明范围的情况下对本文描述和示出的构造和方法进行各种修改，因此意图在于包含在前面的描述中或示于附图中的所有内容都应该解释为例示性而非限制性。因此，本发明的广度和范围不应该被以上描述的任何示例性实施例所限制，而是应该仅仅由所附权利要求及其等同物限定。
