Abstract
根据本发明的用于提升手术的缝合线由不可拉伸的医用线组成,医用线包括形成在两侧并固定在皮肤上的固定部;以及位于固定部之间,赋予结构弹性的可变部,从而固定部和可变部形成为无需单独的连接结构的连续连接的一体形医用线。
Description
技术领域
本发明涉及一种用于埋线手术的线,更具体地,涉及在使用相对不灵活的通常医用线在提升部位牢固固定而不下垂的情况下,在医用线的任何部分形成结构上可拉伸的可变部,使得即使微笑或打哈欠等肌肉明显移动,治疗区域也不会引起疼痛,医用线也不会断裂的具有弹性可变部的提升线。
背景技术
最近,随着人们对皮肤美容的兴趣增加,使用医用线改善皮肤下垂或皱纹的埋线疗法得到了开发和广泛应用。
通过埋线疗法***的医用线刺激和拉动周围的皮肤组织以增强肌肉或改善皮肤的下垂或皱纹,并随着时间的推移被吸收到治疗的皮肤中。
另外,这种缠线疗法所用的线通常是通过插线器操作的,该插线器在前后方向上延伸,在后端有一个带有手柄的管状***针,一端***到所述***针中,另一端暴露在外面,并且包括向后延伸的线。
穿线器为,当***针***人体时,线被***针拉入体内,若在线到达人体内所需部位时将***针从人体中拔出,则只有线留在人体内。因此,留在人体内的线会牵拉并固定人体内的组织,从而改善皮肤下垂或皱纹。
另一方面,为了通过将线***人体来改善皱纹或保持皮肤组织处于弹性状态,***线的直径越大,可以获得越大的效果。然而,当所述***针的直径增加时,由于疼痛和副作用等原因,***针的直径受到限制,******针的线的直径也被限制在预定范围内。
图1示出具有现有直线形状的用于提升手术的缝合线1,并且缝合线围绕某一点被分成第一区域及第二区域,在第一区域a及第二区域b的周边,形成多个以预定角度倾斜以彼此面对的突起,使得第一区域中的突起提升下垂的皮肤,第二区域的突起用作锚,以防止凸起的组织再次下垂。
然而,由于具有这种直线形状的现有的提升手术用缝合线1仅用于在皮下拉动皮肤的作用,因此皮肤持续保持在刚性状态,存在不可能自然地皱眉或微笑的问题。
此外,由于大部分缝合线是由不可拉伸的材料制成,当被治疗的肌肉打哈欠或大笑等时,会在治疗区域引起疼痛或组织撕裂,严重的情况下,提升手术缝合线断裂,降低提升效果。
本发明提出一种能够有效解决现有的提升手术缝合线的问题的新型的提升手术缝合线。
发明内容
要解决的技术问题
本发明是鉴于所述诸多问题而提出的,其目的在于,提供一种能够通过没有可拉伸结构的固定部牢固地抬起提升部分而不会下垂同时,通过在运动量大的部分形成结构上可拉伸的可变部,从而即使微笑或打哈欠等肌肉(组织)剧烈运动时也能够防止疼痛和断线的用于提升手术的缝合线。
此外,本发明提供一种可以通过使用压制、模制、激光、超声波加工等的简单方法制造,从而降低制造成本的用于提升手术的缝合线。
技术方案
为了实现所述目的,本发明的用于提升手术的医用线,作为用于提升手术的医用线,其特征在于,所述医用线(100)形成为沿纵向划分为第一区域和第二区域,所述第一区域包括具有锐角倾斜钳口的固定槽的固定部,以医用线的外周嵌入被手术者的皮下组织,所述第二区域在医用线的外周两侧交替地形成伸缩槽,包括具有结构弹性的可变部,当施加外力时,所述可变部的伸缩槽与伸缩槽之间的连接部分增加,从而使医用线具有弹性。
在所述第二区域的可变部之间形成通过嵌入被手术者的皮下组织来固定的锐角倾斜钳口,所述固定槽为包括倾斜面和锐角倾斜钳口的非对称结构。
在所述固定槽的锐角倾斜钳口的后方隔开预定距离的位置处形成有凹入的弯折槽,当所述锐角倾斜钳口嵌入被手术者的皮下组织时,弯折槽发生弯曲和转动,从而所述锐角倾斜钳口的锐角倾斜钳口进一步向医用线的外周方向突出,并通过嵌入被手术者的皮下组织而牢固地固定。
所述可变部通过挖出缝合线而形成弹簧的形状,从而沿着医用线的长度方向螺旋地连接,所述伸缩槽的深度h大于医用线中心至外周面的直线距离H。
有益效果
根据本发明的用于提升手术的缝合线一体地形成用于通过使用单根医用线牢固地固定提升区域以便不会下垂的第一区域,以及在结构上设计为可拉伸并嵌入到运动大的部位的第二区域,可以牢固地固定在人体组织上,使提升区域不会下垂,即使微笑或打哈欠等肌肉(组织)剧烈运动时,也可以防止疼痛并防止断线。
此外,本发明可以使用相对便宜的非伸缩性医用线,通过冲压、成型、激光、超声波加工等,可以比较简单地形成可伸缩的可变部,从而降低制造成本。
此外,即使本发明是使用相同直径的线来制造,所述锐角倾斜钳口后部开有弯曲槽,以释放支撑锐角倾斜钳口不被推回的支撑力,使得所述锐角倾斜钳口在深入人体组织时,向填充弯曲槽的方向弯曲旋转,进一步向缝合线外侧突出,起到锚固作用,使提升部分更加牢固固定。

具体实施方式
在通过以下本发明的优选实施例进行详细描述之前,本说明书和权利要求中使用的术语或词语不应被解释为限于常规或字典含义,应理解为与本发明的技术思想一致的含义和概念。
在整个说明书中,当部件“包括”某个组件时,除非另有说明,否则意味着可以进一步包括其他组件,而不是排除其他组件。
在下文中,将参照图2描述本发明的优选实施例。然而,本发明的范围不限于以下优选实施例,本领域技术人员可以在本发明的范围内实施在本说明书描述的内容的各种修改形式。
如图2所示,根据本发明的用于提升手术的缝合线,即用于提升手术的医用线包括重复形成多个固定部200的第一区域110和交替重复形成固定部200和可变部300的第二区域120。
形成于所述第一区域110和第二区域120的局部的固定部200包括凹入医用线的外周面的固定槽130,该固定槽130优选地形成为包括倾斜面140和锐角倾斜钳口150的不对称结构(参见图4)。
形成于所述固定槽130一侧的锐角倾斜钳口150形成为小于90度的锐角倾斜钳口,使得在手术过程中,锐角倾斜钳口会深入人体组织,起着锚一样固定的作用。
此外,在所述第二区域120的情况下,在医用线的两侧形成呈锯齿形形成包括U形或V形伸缩槽的可变部,以便在施加外力时,所述伸缩槽之间的连接部像弹簧一样被拉伸以具有结构弹性。另外,在所述可变部与可变部之间形成有具有锐角倾斜钳口的固定槽,用于嵌入到人体组织时牢固地固定在提升部位。
此外,在一些情况下,第一区域和第二区域沿着所述医用线的纵向重复,并且第一区域和第二区域具备至少一个时均可以实施并且落入本发明的范围内。
此外,当具有固定槽的第一区域设置在具有所述可变部的第二区域的两侧时,可以仅在所述第二区域中形成可变部,并且可以仅在第一区域中形成固定槽。
形成在所述固定槽200一侧的锐角倾斜钳口150可以通过超声波或精细刀片加工在医用线的外圆周表面上制造。
此外,所述医用线通常使用非弹性材料,但在某些情况下,即使是由柔性材料制成,第一区域是没有可变结构的固定部,若具有可变结构的可变部形成在第二区域中,本发明可以实现所寻求的防止疼痛和防止断线的目的。
另外,在图3至图5中,示出作为截面为圆形的直丝,但为了增大表面积,更有效地形成突起,也可以设为截面非圆形。这些非圆形横截面可以形成椭圆形、三角形、正方形、平行六面体、梯形、菱形、五边形、六边形、十字形等。这些医用纱线是使用具有圆形横截面的模具通过切割挤出成型的聚合物长丝来制造的,因此可以将挤出模具的横截面改变为所需的特定形状的横截面形状,因此也可以制造具有非圆形横截面的医用线。
对于本发明中使用的医用线(纱线),可以使用如聚二恶烷酮(PDO)、聚乳酸(PLA)或聚乙交酯(PGA)等可生物降解聚合物的材料。
如图3所示,形成于可变部300的伸缩槽160的深度h大于制造提升手术缝合线时使用的从纱线中心到缝合线外周的直线距离H的值。
在可变部300的情况下,如上所述,多个V形或U形弯曲槽或凹槽沿左右方向交替形成,从而沿纵向左右或上下方向交替形成,由于这种交替结构形成的结构,可以非伸缩性医用线赋予结构弹性。
如图3所示,在根据本发明的用于提升手术的缝合线的第二区域120中,一对固定部200之间的V形或U形伸缩槽160形成有左右交替的可变部300,可以包括多个可变部300的基本重复单元U。
在本发明的另一实施例中,如图5所示,在距所述固定槽130后部预定距离的位置处形成有用于释放锐角倾斜钳口的支撑力的弯曲槽160,所述锐角倾斜钳口在嵌入人体组织时,由于向弯曲槽的填充方向弯曲和旋转,因此向外突出更多,更深入人体组织,可以起到牢固固定的作用。
固定部200的附加弯曲槽160可以选择性地应用于根据本发明的用于提升手术的缝合线。
在本发明的另一个实施例中,可变部300可以通过沿医用线100的纵向以螺旋形状挖出来制造,此时,所述可变部300沿医用线100的长度方向挖出螺旋状的伸缩槽,使伸缩槽之间的连接部加工成弹簧形状,即使使用非弹性材料,也可以有效地提供结构弹性。
即使使用相对便宜且没有弹力的医用线,可变部位于两个固定部之间的结构是一体成型的,因此嵌入被手术者皮下组织后,会根据肌肉(组织)的运动而自然松弛或收缩。
根据本发明的用于提升手术的缝合线彼此间隔开并且位于形成在医用线的外圆周表面上的固定部200之间,不是由于线的弹性,而是设有具有V形或U形伸缩槽的可变部300,通过使包含这些的基本重复单元重复预定次数,不仅可以根据皮肤肌肉的运动自然地放松和收缩,而且通过在形成有固定部200的医用线中形成一体结构而不是单独的联接结构,从而具有在稳定固定状态下能够有效收缩和放松的独特效果。
此外,由于固定部200始终保持与皮肤的结合力,同时,由于始终与固定部一体形成的连续可变部300的结构弹性,具有同时具有弹性恢复力的优点。
产业上的利用可能性
本发明提供一种能够通过没有可拉伸结构的固定部牢固地抬起提升部分而不会下垂同时,通过在运动量大的部分形成结构上可拉伸的可变部,从而即使微笑或打哈欠等肌肉(组织)剧烈运动时也能够防止疼痛和断线的用于提升手术的缝合线,提出了一种形成为沿纵向分为第一区域和第二区域的用于提升手术的医用线,当施加外力时,所述可变部的伸缩槽与伸缩槽之间的连接部分增加,从而使医用线具有弹性的技术特征,从而具有工业实用性。
Claims (6)
1.一种用于提升手术的医用线,作为用于提升手术的医用线,其特征在于,所述医用线(100)形成为沿纵向划分为第一区域和第二区域,
所述第一区域包括具有锐角倾斜钳口的固定槽的固定部,以医用线的外周嵌入被手术者的皮下组织,
所述第二区域在医用线的外周两侧交替地形成伸缩槽,包括具有结构弹性的可变部,当施加外力时,所述可变部的伸缩槽与伸缩槽之间的连接部分增加,从而使医用线具有弹性。
2.根据权利要求1所述的用于提升手术的医用线,其特征在于,在所述第二区域的可变部之间形成具有锐角倾斜钳口的固定槽,从而可以通过嵌入被手术者的皮下组织来固定。
3.根据权利要求1或2所述的用于提升手术的医用线,其特征在于,所述固定槽为包括倾斜面和锐角倾斜钳口的非对称结构。
4.根据权利要求3所述的用于提升手术的医用线,其特征在于,在所述固定槽的锐角倾斜钳口的后方隔开预定距离的位置处形成有凹入的弯折槽,当所述锐角倾斜钳口嵌入被手术者的皮下组织时,弯折槽发生弯曲和转动,从而所述锐角倾斜钳口的锐角倾斜钳口进一步向医用线的外周方向突出,并通过嵌入被手术者的皮下组织而牢固地固定。
5.根据权利要求1所述的用于提升手术的医用线,其特征在于,所述可变部通过挖出缝合线而形成弹簧的形状,从而沿着医用线的长度方向螺旋地连接。
6.根据权利要求1所述的用于提升手术的医用线,其特征在于,所述伸缩槽的深度(h)大于医用线中心至外周面的直线距离(H)。
