Description

医疗支撑装置
技术领域
本发明涉及一种用于在人体部位中使用的医疗支撑装置，以及生产和使用该医疗支撑装置的方法。
背景技术
目前已知的假体填充有填充物，例如硅胶或生理盐水。然而，假体的填充或封装总是存在泄漏的风险。
还已知，使用基质来支撑人体部位内的假体，该基质可以被人体吸收或不能被人体吸收。
发明内容
本发明的目的在于能够支撑和/或增强人体部位而没有先前已知的缺点。
根据本发明的第一方面，提供了一种在人体部位中使用的医疗支撑装置。该医疗支撑装置包括至少一个壁形部分，所述壁形部分具有第一侧和第二侧，所述第一侧呈现为从平面伸出的凸起，所述壁形部分的第二侧具有对应的腔体，腔体例如是圆顶形，其中，所述医疗支撑装置包括弹性体。壁形部分绕一个以上的轴弯曲或具有悬垂形状。所述医疗支撑装置从所述平面通向腔体，即从不闭合，例如填充有液体硅胶或生理盐水的普通乳房假体。
使用根据本发明的医疗支撑装置，将可以将内源性组织和/或脂肪和/或添加材料(例如透明质酸)保持在人体部位内的适当位置。这种解决方案的优点是，当充满内源性组织和/或脂肪时，它对X射线辐射是可透过的，这对于安全的乳房X线照相是很重要的。
根据一个实施方式，壁厚(即第一侧和第二侧之间的壁厚)在整个壁形部分上基本相同。优选地，医疗支架是预成形的。
根据一个实施方式，平面中的边沿至少部分地沿着腔体的边缘而存在。当将医疗支撑装置固定到身体部位的组织上时，边沿将使缝合线更容易地施加到医疗支撑装置上。附接医疗支撑装置又将导致更少的假体的错位(例如旋转)移动、以及横向移动和向底部移动问题。它还可以确保医疗支撑装置腔体中的材料保持在适当位置。
根据一个实施方式，该装置由弹性体制成并且至少在边沿处设有基质。
根据一个实施方式，该装置由弹性体制成并且至少部分地在壁形部分的第二侧、腔体侧处设有基质。
根据一个实施方式，该装置用在乳房中，优选用在女性的乳房中。
根据本发明的第二方面，提供了一种制造所提供的医疗支撑装置的方法，由此将具有期望形状的芯轴浸渍在未硬化的弹性体中以成形所述装置。优选地，在浸渍之后在所述芯轴或所述装置上布置至少一块基质。
根据本发明的第三方面，提供了一种使用这种医疗支持装置的方法。形成无封装材料假体，其中，医疗支撑装置将内源性组织和/或脂肪和/或添加材料(例如透明质酸)保持在人体部位内的适当位置。
附图说明
本发明将参考以下附图进行详细描述，其中：
图1a，1b和1c分别示出了本发明的实施方式的剖视图、俯视图和侧视图。
图2a、2b、2c和2d分别示出了具有边沿的不同实施方式的横截面图和两个俯视图。
图3a-g示出了本发明的不同实施方式的剖视图。
图4a和4b从侧面示出了不同形状的实施方式。
图5a和5b示出了具有不同形状的实施方式的俯视图。
图6a、6b和6c示出了用于生产本发明实施方式的芯轴的不同实施方式。
图7示出了使用本发明的示例。
图8示出了使用本发明的示例。
具体实施方式
图1a，1b和1c示出了本发明的医疗支撑装置1的实施方式。医疗支撑装置1至少包括壁形部分2。壁形部分2具有第一侧3和第二侧5，第一侧3示出为从平面4伸出的凸起，第二侧5具有对应的腔体。例如，壁形部分2可以具有圆顶形状，然而，根据在人体中的支撑目的，壁形部分2可以具有任何特定的形状。
壁形部分2在至少两个不同的虚拟轴上弯曲或悬垂，即它不具有部分圆柱体的形状。优选地，在凸起/腔体上，壁形部分2具有基本相同的在第一侧3和第二侧5之间的厚度。在图1b中，以从第一侧2观看的俯视图示出医疗支撑装置1。在所示的实施方式中，该装置具有基本圆形的覆盖区，然而尽管任何形状都是可行的。在图1c中，从侧面示出图1a和b的实施方式。
医疗支撑装置1用于将内源性组织和/或脂肪支撑在人体部位中的适当位置。尽管医疗支撑装置1可能主要用于女性的乳房，但任何合适的身体部位(例如在臀部或乳房中)都可以接纳医疗支撑装置1。医疗支撑装置1将支撑内源性组织、或脂肪、或内源性组织和脂肪以抵抗重力。还可以构思添加其他适合在人体中的材料，例如透明质酸。或者仅在医疗支撑装置1的腔体部分使用其他材料。
医疗支撑装置1包括弹性体或基质，或包括弹性体和基质两者。弹性体材料可以是适用于人体并且柔韧的任何种类的弹性体。弹性体可以例如是硅橡胶，优选用于乳房假体的类型的硅橡胶。基质可由生物或合成材料或其组合构成。基质可以包括可吸收的和/或不可吸收的材料。例如，基质可以是脱细胞真皮基质。
在图2a中，以横截面示出医疗支撑装置1的实施方式，其中，边沿6的至少一部分设置在平面4中的腔体或凸起的边缘7处。与仅附接边缘7相比，边沿6的至少一部分可以更容易地附接到人体中的组织。优选地，为此可以使用任何可吸收的或不可吸收的缝合线。
在图2b中以平面图示出了一个实施方式，其中，设置了边沿6的多个部分，并且在图2c中示出了围绕边缘7的完整边沿6。在图2d中，示出了另一个实施方式，其中，壁形部分2在其上部被切除8并且具有围绕在平面4中留下的边缘7的边沿6，使得当其附接到人体组织时形成口袋。图2中所示的所有实施方式可以包括弹性体和/或基质。
现在将在图3a-g中举例说明弹性体和基质的组合的不同实施方式。在图3a中所示出的圆顶形的医疗支撑装置1由弹性体制成并且具有设置在下部区域中的第二侧5上的基质9的一部分。
显然，基质9可以设置在整个第二侧5上，或者如图3b所示，设置在整个第一侧3上，或者设置在第一侧3的一部分上。图3c示出了具有边沿6的医疗支撑装置1，其中，基质9设置在与壁状部分2的第二侧5相同侧的边沿6处。还可以构思在另一侧(如图3f所示)或两侧都具有基质9。在图3d中，基质9设置在腔体、第二侧5和边沿6处。在图3e和3g中，基质9分别设置在腔体和凸起的下部，以及沿着边沿6设置。
显然，医疗支撑装置1的形状可以根据其用途和目的而不同。图4a示出了基本圆顶的形状，优选地为部分球体，并且图4b中示出了解剖形状。投影以及投影点12的高度也可以不同。医疗支撑装置1的覆盖区也可以根据其用途和目的而不同。图5a和5b示出了两个不同的示例，圆形具有相同的高度和宽度，或与宽度相比分别具有不同的高度。高度可以比宽度长，或宽度可以比高度长。例如，覆盖区可以是椭圆形或如图5b所示的水滴形。
现在将描述如何生产医疗支撑装置1的示例。图6a、6b和6c中示出了三个不同的芯轴。芯轴浸渍在处于流动状态的弹性体中。然后其被占据，弹性体硬化成柔韧的状态。例如，这可以通过加热或添加物质来实现。通常重复浸渍所需的次数。将弹性体从芯轴上取下，并根据需要切割成所需的形状。可以将其翻转，即弹性体的最靠近芯轴的表面将变为凸出侧，即第一侧3。
如果需要特殊表面(例如带纹理的表面)，可以将该特殊表面分别设置在第一侧3或第二侧5、或设置在第一侧3和第二侧5。通过在芯轴上设置有表面结构，可以提供从光滑到粗糙的不同粗糙度。还可以在硬化之前在最外层上压印有纹理。例如，可以使用聚氨酯或盐进行压印。
如果需要边沿6，则使用根据图6b和6c的芯轴。如果需要弹性体和基质的组合，则基质的部分可以在浸渍之前布置在芯轴的所需位置处或布置在整个芯轴表面上。替代地，在浸渍之后、硬化之前布置基质。
医疗支撑装置1可以以多种尺寸设置，从而能够找到适合每个患者的特殊需要的尺寸。
图7中示出了医疗支撑装置1的使用。医疗支撑装置1定位于人体部位10(在该示例中是女性乳房)的内部。在本示例中，深层腺体组织和/或脂肪被分离并且其一部分设置在腔体内，即在医疗支撑装置1的第二侧5上。医疗支撑装置用缝合线11附接。缝合线优选为可吸收类型。医疗支撑装置可以例如附接到肌肉(在该所示出例子中是胸肌)中。除了腺体组织或仅脂肪或仅其他组织之外，还可构思在医疗支撑装置的腔体内设置脂肪或其他组织，优选为内源性组织。也可以构思在腔体内单独地或与任何一种或多种内源性组织混合添加透明质酸或其他医用注射材料。
图8中示出了通过注射器可以将例如透明质酸或脂肪添加到已经在人体部位10中适当位置的医疗支撑装置的腔体中。与填充硅胶的普通乳房假体一样，由于没有有害物质泄漏，因而这种穿刺不会造成任何危害。
