Integrated endovascular phantom

血管内手术在许多关键手术中得到了广泛的应用，在这些手术中开发用于这些手术的幻影在外科训练和手术过程本身中都有很多好处。本项目将根据医师的要求，设计一种可用于血管内手术训练的紧凑型假体。在过去和相关的研究项目中，所使用的幻影既昂贵又不是为特定应用定制的。因此，为了有效地保证所需的性能，我们需要开发：精确的血管内动脉影；把动脉模型整合到一个更大的，紧凑的，代表人体腹部的模型中，这样我们就可以有一个真实的机制，把稳定的动脉嵌入其中。所提出的集成假体不仅是出于美观的原因，而且也是为了精确和一致地确保内部动脉的位置。这一过程不仅设置繁琐、耗时，而且在反复使用之间，在保证人体幻体内柔性血管的稳定性方面也不可靠。与之前的训练系统中设计和使用的假体不同，拟议的假体将专门设计用于血管内手术训练，其中导管从股动脉插入血管。由于导管在血管内的导航和弯曲的准确性需要动脉壁的支持，因此选择制造动脉假体的材料特性对于所需的程序至关重要。幻像需要在几何和纹理材料上准确地代表动脉。定制的幻影可以在术前练习中使用。实践定制的幻影将使外科医生熟悉个别患者的独特情况，从而提高手术效果。从长远来看，加拿大将有更好的医疗保健服务和经济效益。

Endovascular surgery is becoming widely deployed for many critical procedures and developing phantoms for use in these procedures has many benefits in surgical training, as well as in the surgery process itself. This project will focus on designing, based on the specification of physicians, a compact phantom that can be used in training for endovascular surgery. During past and related research projects the phantoms used are both expensive and not customized for specific applications. Thus, in order to guarantee the required performance efficiently we need to develop: an accurate Endovascular Phantom of the arteries; and integrate the arteries phantom into a larger compact phantom component representing the human abdomen, so that we can have a realistic mechanism embedding stable arteries inside. The proposed integrated phantom is necessary not just for aesthetic reasons, but also to precisely and consistently secure the placements of the internal arteries. This process is not only cumbersome and time consuming to set up, but also unreliable in terms of guaranteeing the stability of the flexible blood vessel inside the body phantom between repeated uses. Unlike the phantoms designed for and used in previous training systems, the proposed phantom will be specifically designed for endovascular surgical training, where a catheter is inserted into the blood vessels from the femoral. Since the accuracy in navigation and bending of the catheter inside the vessels require the support of the artery walls, the material properties chosen to fabricate the artery phantom is critical for the desired procedures. The phantom needs to accurately represent the arteries in both geometry and texture material. The customized phantoms can be used in a pre-operative practice session. Practice on customized phantoms will familiarize the surgeons with the unique conditions of individual patients and thus improve surgical performance. In the long term, there will be better healthcare services and economic benefits in Canada.
