摘　　要：离体器官机械灌注技术可以有效解决供体短缺的问题,减少术后并发症的风险,是近年来器官保存的研究热点。为了解决肝脏移植转运过程中因储肝容器的结构缺陷导致的器官损伤问题,提出了一种基于肝脏仿生形态进行储肝容器的结构优化设计的方法。首先通过医学三维重建软件Mimics软件,对人体肝脏CT图像进行扫描,重建肝脏三维模型,然后计算肝脏体积,最后根据计算结果基于肝脏仿生形态设计储肝容器的结构。新的储肝容器结构能模仿肝脏在人体内的形态,结构稳定,大大减轻了转运时肝脏在储肝容器内的振动,便于机械灌注,更好地维持肝脏生理机能,提升了肝脏移植成功率。该结构设计可以为以后储肝容器的设计制造提供参考。The isolated organ mechanical perfusion technique can effectively solve the problem of donor shortage and reduce the risk of postoperative complications.In order to solve the problem of organ damage caused by the structural defects of liver storage vessels during liver transplantation and transport,a structural optimization design method based on the biomimetic morphology of liver storage vessels is proposed.First,the CT images of the human liver are scanned through the medical 3D reconstruction software Mimics,and the 3D liver model is reconstructed,and then the liver size and volume are calculated.Finally,depending on the calculation results,structural of the liver storage container is designed based on the biomimetic morphology of the liver.The new liver storage container imitates the liver’s shape in the human body,the liver can be kept stable,the liver vibration in the liver storage container can be greatly reduced,which can not only facilitate mechanical perfusion,but also better maintain the liver physiological function and improve the success rate of liver transplantation.The structure design can provide a reference for the future design and manufacture of liver storage containers.
