Description

胚胎移植套管稳定器
技术领域
胚胎移植套管稳定器是一种附接到阴道窥器的装置,该装置允许套管的滑动、放置和牢固固定,以执行胚胎移植。胚胎移植套管稳定器防止使用者的手的微小移动,以减少子宫颈管内水平(intracervical level)的颤动,并避免对子宫颈管的伤害、血管的破裂和碎屑的产生。
背景技术
在胚胎移植过程中,必须在需要精确度的一段时间内执行各种复杂的静态手动操纵。这些操纵由于手的阻塞及其移动到一个位置而影响了移动性,从而导致所述手保持固定。这会导致麻木、疲倦,并且在以交错移动的方式撤离该位置时,会导致该技术无法重现。
另外,由于子宫颈插入导管从其被引入到阴道窥器后就缺乏稳定性,所以外科医生的手被阻塞(如上所述)。
为了解决这些问题,已经设计了本发明的装置以便有效地解决以下问题:
a)为导管提供稳定性;
b)一旦导管被稳定,就避免使用外科医生的手;
c)使外科医生的双手保持自由,以便它们可以在需要进行的手术的其他部分中相互配合(interact),在要执行的技术中利用它们自身的人体工程学原理,此外通常还有助于外科医生的姿势。
发明内容
本发明涉及一种胚胎移植套管稳定器,其包括:具有远端和近端的主体;该主体具有纵向凹槽;该远端具有至少一个空腔;并且该近端具有支撑元件。
附图说明
可以参考附图来描述说明性形态,这些附图涉及:
图1是本发明的胚胎移植套管稳定器的正视图;
图2是本发明的胚胎移植套管稳定器的远端的详细视图;
图3是与阴道窥镜联接的、本发明的胚胎移植套管稳定器的透视图。
具体实施方式
以下详细描述仅是示例性的,并非旨在限制所公开的形态或所述形态的应用和使用。如本文中所使用的,词语“示例性的”或“说明性的”是指“用作示例、实例或说明”,本文中被描述为“示例性的”或“说明性的”的任何实施方式均不必被解释为比其他实施方式更优选或更有利。下文描述的所有实施方式都是示例性的实施方式,提供这些示例性的实施方式是为了使本领域技术人员能够制作或使用本公开的形态,并非旨在限制本公开的范围。出于本说明的目的,术语“上”、“下”、“左”、“后”、“右”、“前”、“竖直”、“水平”及其派生词都将涉及本发明,如附图中所定向的。此外,不受以上技术领域、背景技术、发明内容或以下详细说明中呈现的任何显式或隐式理论的约束。还应理解,附图中所示出的以及下文的说明书中所述的特定装置和过程只是所附权利要求书中限定的发明构思的示例性形态。因此,除非权利要求书另有明确说明,否则与本文中所述的形态有关的具体尺寸和其他物理特性不应被视为限制性的。
图1示出了胚胎移植套管稳定器10,其包括:主体11,其优选为纵长的,该主体具有纵向凹槽12,所述纵向凹槽12与主体11的纵向轴线对齐;和测量刻度19,该测量刻度19位于纵向凹槽12的一侧上。
所述主体11具有在纵向方向上彼此相反的远端13和近端14;在图2中,可以看到所述远端13具有至少一个空腔15,所述空腔15与所述纵向轴线对齐,另外,优选的空腔15的数量为三个空腔,所述三个空腔具有彼此不同的三个直径,使得具有较大直径的空腔位于远端13的最外侧部分中,而具有较小直径的空腔位于该远端的最内侧部分中。
近端14具有支撑元件16,所述支撑元件16包括朝着所述近端14纵向延伸的一对臂17、以及布置在臂17之间的弧形部(arc)18。
胚胎移植套管稳定器10由透明材料制成,该透明材料选自以下的组:晶体聚苯乙烯、固体聚碳酸酯、聚丙烯、丙烯酸、PET、PVC、玻璃、晶体、甘蔗渣、小麦渣、龙舌兰纤维以及PLA等。
在图3中可见,胚胎移植套管稳定器10被构造成通过联接器件21(优选为螺钉)与阴道窥镜20联接,该联接器件21穿过纵向凹槽12并紧固到所述阴道窥镜20。
胚胎移植套管稳定器10的使用方法如下:
1.在开始胚胎移植手术之前,应将该胚胎移植套管稳定器的纵向凹槽放置在阴道窥镜20的Y形手柄上,并用镜柄螺母(mirror handle nut)固定。
2.将患者置于截石位(lithotomy position),并进行无菌和消毒。使用者用右手以45°的角度取下阴道窥镜20,并将其斜向插入患者的阴道内。
3.通过打开阴道窥镜20的上叶片和下叶片(leaves),使用者可以看到宫颈口的存在,并用窥镜20的杠杆螺母固定所期望的位置,以对患者进行宫颈检查。
4.胚胎移植插管稳定器10的支撑元件16允许使用者用食指在两侧(左右两侧)执行旋转最多达90°,以允许通过引导窥镜20的上下叶片进行阴道清洁。
5.胚胎移植套管稳定器10的纵向狭槽12允许使用者基于渐进刻度19调节该稳定器的高度,使用引导窥镜20的手柄螺母(handle nut)设定期望的水平。
6.最后,放置胚胎移植套管并使其在胚胎移植套管稳定器10的所述至少一个空腔15上滑动,一旦位于期望的位置,就可以固定该胚胎移植套管以防止手在执行胚胎移植时的移动。
本发明适用于各种修改和替代构造,其中一些在下面的附图中详细示出。然而,应该清楚的是,其意图不是将本发明限制为特定形态或形式,相反,本发明应当涵盖作为其范围的一部分的各种修改、增加和变型。对于本领域技术人员,通过研读该详细说明和附图,本发明的各个独立方面和优点将变得明显。
本领域技术人员可以修改本文中所述的结构。然而,应该注意,本说明涉及本发明的优选形态,并且仅是出于说明性目的而提供的,不应被理解为限制本发明。在本发明的精神范围内的所有显而易见的修改(例如构成本发明的元件的形状、材料和尺寸的改变)都应被认为在所附权利要求书的范围内。
