Description

医疗手术用的锚/缝线
技术领域
本发明涉及医疗手术中用的锚和缝线，特别涉及适用于将腱、肌肉或组织粘附于病人骨头上的组合的缝线锁和锚。
发明背景
如医疗技术的专业人员熟知的，医疗手术中完成的缝线打结绑扎如将组织绑扎在骨头上确实是外科医生进行的手术中最薄弱的环节之一。手术采用关节内窥镜检查，或者部分或全部打开待修复的区域，就属于这种情况。众所周知，该技术中外科医生在缝线上进行的关节内窥镜检查的打结没有两个是相同的，同样知道的是，一个熟知的问题是，外科医生不可能打结到以最佳方式将组织固定在骨头上。换句话说，绑扎的组织不可能完全紧靠或粘附在骨头上。
虽然本发明考虑的是处理肌腱套撕裂，目的是获得一种解决上述打结问题的缝线，但显然，本发明的器械也可用于其它外科手术。肌腱套撕裂十分普遍，由于将组织绑扎到骨头上很困难，这对外科医生成为越来越严重的问题。肌腱套是一组通过其腱而附着在上臂骨(肱骨)顶部上的肌肉。这些组织中的撕裂常需要医生修复。取决于撕裂的严重性，留给外科医生的选择，或者是结合关节内窥镜检查和小切口的小型切开修复的关节内窥镜检查修复，或者是切开外科手术。不管是那种手术，组织最终都绑扎在骨头上，常常利用一个固定在骨头中的锚和一根绑扎在组织和锚上而后打结的缝线。本发明指向一种独特的装置，该装置将组织固定在骨头上并合并地调整，使得该组织绑扎在骨头上而尽可能密切地绑紧在骨头上。因此，本发明涉及一种用于将组织绑扎到骨头上的器械，一种自动固定缝线的器械，一种当使用本发明的装置时外科医生能操纵该缝线而使组织尽可能密切地绑紧在骨头上的方法。
这种修复肩膀的器械和方法完全不同于Opus医生制成的自动套系统，该系统利用灵巧缝合法缝线装置和大n头状骨无结固定植入物。该缝线装置利用一种机械褥垫缝合法来消除打结绑扎。该装置将缝合直接安置在组织中。一旦缝合置入套中，外科医生就加载和展开大n头状骨无结植入物。该手术可与本发明区分清楚。
发明概要
本发明的一个目的是，提供一种医疗手术用的绑扎和锁定缝线端部的改进的装置。
本发明的一个特点是提供一种缝线锁定装置，该装置包括一个插入一空心圆筒形主体内而沿轴向向该主体中的一个壁移动的销，并提供在空心圆筒形主体中的孔，缝线的两端穿过孔内，而该销向上移动而靠着该壁被推动，从而在该销和该壁之间挤压缝线的线长。轴向的槽形成于该主体的侧壁中而用于当销在该主体中沿轴向移动时引导该销。一个凹部形成于该主体中并限定一壁，该壁的轮廓与该销互补。该凹部的顶面做成凸起的表面或锯齿形，而该销为多边形，其中包括平行于凹部侧壁而取向的平表面。该圆筒形主体的外径可以有对置的平面，其中设置这些孔，而这些孔允许缝线穿过该主体，从而使缝线安置在销和壁之间。
本发明的又一目的是将该缝线锁定装置固定在目前技术水平的锚上，并修改该锚的脆性轴而包括一个钻孔以装入该销。利用一个类似枪的已知工具将该锚安置到骨头中。枪的驱动使销进入凹部而挤压缝线线长并将其锁定就位。
本发明的一个目的是提供一种用于医疗手术的方法，用于当外科医生拉动缝线通过本发明的缝线锁定装置时将锚安置在骨头中，并同时展开该锚而将组织紧绑到骨头表面上。医生将缝线穿过组织而后穿入主体上形成的一个孔，然后穿过主体的空心并穿过沿直径方向对置的孔而在销和锯齿形壁之间安置缝线线长之一，然后将缝线线长之另一穿过主体中形成的沿直径方向对置的孔，使得缝线安置在销和锯齿形壁之间。
从下列描述和附图将更加清楚本发明的上述和其它特点。

发明详述
如上所述，虽然本发明被认为用于在处理病人的肌腱套的医疗手术中的绑扎缝线，但如该技术的专业人员将理解的，本发明也可以用于其它医疗手术，包括(但不限于)不仅用于将组织绑扎在骨头上，而且将组织绑扎在组织上等等，只要该用于将锚插入人体部分的工具具有驱动该缝线锁定装置的能力或使用一个没有该锚的类似工具。
如图1和图2中最清楚地看到的，本发明的缝线锁定装置10固定在一个熟知的锚12上，锚12包括一个脆性的轴14(修改成适应本发明)，其远端是一个尖端16(图9)和可弯曲部分12a，后者包括环状底环部分18、可弯曲的臂或翼26和一个顶环部分20，顶环20与缝线锁定装置10接合或与其制成一体。当展开时，锚12的翼26如图所示地弯曲而操作，极像一个帆鳍栓并被强制卡入骨头结构中而将锚固定就位。在此前的锚中，缝线24将穿过组织30并通过锚中形成的孔(未示出)，而缝线24的两端由外科医生以熟知方式打结。显然，如上所述，因为由医生打结，所以医生很难又绑缝线又同时迫使组织附着在骨头表面附近。如下面将更详细地描述的，本发明的缝线锁定装置10基本上将缝线结扎和锁定就位，从而解决了这个问题。
回来参考图1和2(所有图中相同的部件其标号相同)，本发明由限定空腔31的大体上圆筒形的主空心体28组成，其端部32向着锚12渐渐缩小并适当地附接在锚12上或与其一体制成，主空心体28还有一个顶部33。主空心体28的侧部或表面34和36可以如图所示地制成扁平。主体28的两侧上在非扁平的表面上制成沿径向的细长槽40，用于当主体28沿轴向移动而固定缝线时引导销42，这在下面将详述。主体28的侧面上在扁平表面上形成一对沿直径方向对置的孔44和46，后者允许缝线在锁42上面穿过主体28。
图3和4基本上是分解图，表示脆性轴14和附接在锚部分12a上的本发明。与此前已知的锚轴几乎相同的脆性轴14被修改成包括一个适合于装入销42的钻孔52。销42装入钻孔52并超过轴14的直径而凸出，以接合槽40。锚轴14的远端或尖端16渐缩成尖锐的点而穿过骨头。在轴14中切削而成的环形槽58使轴成为易折断的，并允许外科医生折断轴的伸出环形槽的部分。(该特点在先有技术的锚中是典型的。)图中主体28固定在锚部分12a上。
图4是图3中的装置转动90度的视图，显示主体20中形成的槽40。相同的槽40形成于主体28的沿直径方向对置的壁上而当其沿轴向移动时形成一个引导销42的凸轮表面。为了装配锚12和缝线锁定机构10，轴14通过主体28和锚部分12a的空心中心部分而插入并适当地固定于其上。钻孔52取向与槽40对准，其后，将销42插入钻孔52，使其在孔两端上的凸出部伸入对置的槽40中。
在完成外科手术中，在病人的皮肤中做出切口而暴露腱或组织或骨头后，使用刀杆、钻等的外科医生将划破骨头而形成一个锚用的起始孔。然后以熟知方式用机械动力的驱动器械或工具41(见图13)安装锚轴14，该工具有时称为“固定器”，可从本发明受让人ANSPACHEFFORT公司买到。如下面将更详细地描述的，工具41允许外科医生将锚驱动到骨头中(如图9和11所示)，并将缝线自动地缝扎和锁定在位置上。
当外科医生已完成医疗手术而需要使用缝线时，医生将缝线穿过组织和通过将缝线线长插入孔44和46内而穿过锚的主体10。如图1、2、5A、5B、5C中所见，缝线形成一个包围被捆绑的主体部分的圈，而当缝线移动到线圈锁定机构中时，该缝线圈被拉紧而有时闭合。外科医生将抽出缝线线长并迫使缝线圈向着主体28的中心孔，从而使得缝线和缝线锁定装置被尽可能拉近组织和骨头地抽出，如图5A、5B、5C、7、8中所示。当医生拉紧缝线时，他开始挤压器械41的柄。工具41的展开将锚压入骨头内而迫使轴14向上，如图5B中所示。工具41的作用迫使销在槽40中移动，当其移动时向着主体28的顶部，直到它装入凹部62。凹部62的顶面61可以是锯齿形的，如64所示，使得当销移至其最上位置时，缝线被迫靠着锯齿形表面61，该处销的力靠着锯齿结合缝线的表面，将缝线挤压于其中，从而将缝线束缚和锁定于位置中而不需医生对缝线打结。应当理解，销是通过工具41的作用而引入锁定位置的。因此，当组织对组织绑扎时(例如)，可以使用缝线锁定机构而不必使锚附接于其上。
如图6中所示，在该实施例中，为了描述，销42的形状为多边形，比如六角形。该形状的目的是保证，当处在锁定位置中时，销42a和42b的侧边缘平行于限定槽62的壁，因而销/壁不会靠着缝线结合而弱化缝线。
如图5B和5C中所示，当锚展开时，轴升高到越过主体28的顶边缘66而暴露环形槽58。在操作的该接合处，在轴的较大直径处形成的外缘59靠着主体28的内表面上形成的台肩61而支承。通过弯曲该轴14，轴14将在该位置(环形槽)处断裂而从锚和主体28上折断，然后被丢弃。由于本发明，通过本发明的创造性的缝线锁和在锁定缝线的过程中外科医生相对于骨头拉紧缝线而使该组织的位置的尽可能靠近骨头这一事实，而将缝线锁定就位。因为由于本发明而消除了至今为止的手工打结，所以医生能够拉成缝线而使该组织紧贴骨头(绑紧)，此时医生会满意这是不会发生后退的最佳位置。换句话说，本发明消除了用手绑扎缝线时通常发生的缝线下垂。
虽然已经用详细的实施例图示和描述了本发明，但该技术的专业人员可以理解，可以对其形式和细节进行各种变化而并不偏离本发明的范围和精神。
