背景止血阀常用于神经介入治疗。我们提出了一种在手术过程中将止血阀固定到手术台上的新颖概念。此外，我们报告了使用 3 维打印机创建的这些新设备的初步体外经验。方法止血阀支架 (HVH) 包括 2 个组件：内部固定器和外部插座。它的设计适合与所有市售旋转止血阀一起使用。 HVH 底部包含磁铁，有助于将其固定在工作台上消毒盖布下方的薄钢板上。我们通过涉及单个操作员放置支架的体外实验评估了 HVH 的功效。结果HVH 可以轻松地连接到旋转止血阀或从旋转止血阀上拆卸。此外，多个 HVH 的使用有助于操作员集中精力进行操作，因为它们可以在多个点持续防止设备发生意外移动。使用 HVH 甚至可以由单个操作员完成支架置入操作。我们观察到，在 2 个 HVH 之间形成支架输送导管环增强了装置控制。结论 HVH 应该比传统方法更有用，特别是在需要对微导管和微导丝进行精细互补控制的情况下。
BackgroundHemostasis valves are commonly used in neurointerventions. We propose a novel concept for fixing hemostasis valves to the operating table during procedures. Moreover, we report our preliminary in vitro experience using these new devices created using a 3-dimensional printer.MethodsThe hemostasis valve holder (HVH) comprises 2 components: an inner fixer and an outer socket. It was designed to be suitable for use with all rotational hemostasis valves commercially available. HVH contains magnets at the bottom that facilitate its attachment to a thin steel board beneath a sterilized drape on the working table. We evaluated the HVH's efficacy via in vitro experiments involving stent placement by a single operator.ResultsHVH allowed easy attachment to and detachment from the rotational hemostasis valve. Moreover, the use of multiple HVHs facilitated operators to concentrate on the procedure because they continuously prevented the unexpected movement of devices at several points. Use of HVHs enables stent placement to be performed even by a single operator. We observed that forming a loop of the stent delivery catheter between 2 HVHs enhanced the device control.ConclusionsHVHs should be more useful than conventional methods, particularly in cases requiring fine complementary control of both a microcatheter and microguidewire.
