Abstract

A profound investigation of the interaction mechanics between blood vessels and guidewires is necessary to achieve safe intervention. An interactive force model between guidewires and blood vessels is established based on cardiovascular fluid dynamics theory and contact mechanics, considering two intervention phases (straight intervention and contact intervention at a corner named “J-vessel”). The contributing factors of the force model, including intervention conditions, guidewire characteristics, and intravascular environment, are analyzed. A series of experiments were performed to validate the availability of the interactive force model and explore the effects of influential factors on intervention force. The intervention force data were collected using a 2-DOF mechanical testing system instrumented with a force sensor. The guidewire diameter and material were found to significantly impact the intervention force. Additionally, the intervention force was influenced by factors such as blood viscosity, blood vessel wall thickness, blood flow velocity, as well as the interventional velocity and interventional mode. The experiment of the intervention in a coronary artery physical vascular model confirms the practicality validation of the predicted force model and can provide an optimized interventional strategy for vascular interventional surgery. The enhanced intervention strategy has resulted in a considerable reduction of approximately 21.97 % in the force exerted on blood vessels, effectively minimizing the potential for complications associated with the interventional surgery.

导丝与血管间介入力的建模和实验研究
为了实现安全介入,有必要对血管和导丝之间的相互作用力学进行深入研究。基于心血管流体动力学理论和接触力学,考虑两个介入阶段(直线介入和 "J 血管 "拐角处的接触介入),建立了导丝与血管之间的相互作用力模型。分析了介入条件、导丝特性和血管内环境等力模型的影响因素。为了验证交互式力模型的可用性并探索影响因素对介入力的影响,进行了一系列实验。介入力数据是使用带有力传感器的 2-DOF 机械测试系统收集的。结果发现,导丝直径和材料对介入力有显著影响。此外,介入力还受到血液粘度、血管壁厚度、血流速度以及介入速度和介入模式等因素的影响。在冠状动脉物理血管模型中的介入实验证实了预测力模型的实用性,并能为血管介入手术提供优化的介入策略。改进后的介入策略使施加在血管上的力大大降低了约 21.97%,有效地减少了介入手术并发症的可能性。
