Abstract

回旋套重构装置，其包含具有至少两个相对末端(2a，2b)的扁平元件(2)，且适于在所述末端(2a，2b)处与患者回旋套的至少一个受损腱相连接；所述扁平元件(2)完全由生物可降解并且可吸收的材料制成。

Description

用于重构回旋套的可吸收装置
本发明的目的是一种用于回旋套(rotator cuff)重构的装置。
本发明具有在肩关节肌腱复合体(通常称为“回旋套”)的一个或更多个点受损情况下的应用。
已经知道存在这样的装置，将其通过缝合手段固定到肩关节的受损肌腱组织(回旋套)上，以恢复关节的功能。
通常，这些装置由不可吸收且刚性的材料制成。例如，已知装置由聚对苯二甲酸乙二醇酯纤维(即)制成。
在这种情况下，这些装置可以在损伤愈合阶段暂时恢复受损的肌腱组织的功能。随后，它们保留在原位，不被移除。
不利的是，用于制造已知装置的材料具有刚性，这就产生了某些问题，首先在于它们即使在完全愈合之后也永久存在于关节中。
首先，甚至在恢复期后，在完全愈合后，装置的过度刚性可引起不希望的装置分离。在这种不利情况下，需要再次对患者进行外科手术以恢复或移除该装置。
此外，即使在愈合期完成之后，装置的过度刚性可导致患者关节运动受到限制。
在任何情况下，即使没有分离，永久存在的该已知类型装置也可因为其尤其是刚性而实际上使患者不适。
在这种情况下，本发明的技术任务是提出一种克服现有技术上述缺点的回旋套重构装置。
特别地，本发明的目的是提供一种用于回旋套重构而不在愈合期后导致任何问题或限制的装置。
具体技术任务和具体目的主要通过回旋套重构装置来达到，该装置包含在一个或更多个所附权利要求中阐述的技术特征。
从重建回旋套装置的一个优选但非排他性实施方案的示例性且因此非限制性的描述中，本发明的其他特征和优点将会更加清楚，如附图所示，其中：
-图1是回旋套重构装置的平面示意图。
参照附图，编号1总体上表示根据本发明的回旋套重构装置。
装置1包含扁平元件2，其具有彼此相对的至少一个第一2a末端和一个第二2b末端。
在使用期间，扁平元件2通过可吸收缝合线固定至回旋套的受损肌腱组织。
扁平元件2具有基本上楔形的形式。换言之，扁平元件2在平面图中是基本为三角形的形式。特别地，扁平元件2具有等腰三角形的形式。
等边的顶点是弧形的。
将等边的顶点定义为扁平元件2的第一末端2a。
将扁平元件2中与顶点相对的底边部分定义为第二末端2b。
根据本发明，装置1的扁平元件2由生物可降解并且可吸收的材料制成。有利地，装置1的扁平元件2完全由生物可降解并且可吸收的材料制成。
优选地，装置1的扁平元件2由PGA纤维织物(聚乙交酯或聚乙醇酸)制成，优选为均聚物。PGA是一种高度生物相容且可吸收的聚合物。具体而言，PGA的吸收时间约为一个月。
有利地，在制造扁平元件2的织物时使用的PGA纤维允许在装置1吸收阶段期间形成肌腱组织。
换言之，扁平元件2在一个月期间内被完全分解，而不留下任何痕迹。同时，它有助于肌腱组织的发育。
此外，一旦装置1被插入，扁平元件2的织物就被血液，特别是血浆浸透，这使得在装置本身上的抗生素药物有效。
扁平元件2的织物可以通过以多种方式编织PGA线来获得，从而产生编织物、纺织物或无纺织物。
优选地，该织物是编织物，还更优选为经编织物(warp knitted fabric)。
在这种情况下，织物具有能够呈现足够小网眼的网状结构的较粗糙表面。
具体而言，其纬线使得其间隙空间小于200μm，优选约160μm，对应于大约等于0.02mm2的平均孔面积。这确保了对尿的抗渗性，防止泄漏。
此外，织物优选是有纹理的，以此方式以便赋予其更大的表面粗糙度。
仍然仅作为示例，织物的厚度基本上为0.3mm到0.6mm，更优选为0.4mm到0.53mm，还更优选基本上为0.45mm。
装置1具有位于扁平元件2的末端2a、2b处的固定区域3，以用于通过可吸收的缝合线将扁平元件2固定到受损的肌腱组织处。
特别地，固定区域3布置在扁平元件2的顶点处。
本发明达成了前述目的。
实际上，在恢复期间该装置的吸收不在患者的关节中留下任何残留。因此，完全愈合后，关节保持完全自由，而不会对患者造成任何不适或障碍。
