“…Other research has studied catheter dynamics by using specialized sensors to measure forces and torques required to overcome sheath or vasculature friction 24. For visualization of the contact between catheter/guidewires and vascular models, photoelastic stress analysis has been used, combined with tracking operator hand motions and proximal catheter motion, to provide technical metrics for measurement of skill 8,23. Other clinical research has relied on 2D catheter tip tracking (from fluoroscopy images) for skill assessment based on the catheter path-length 21…”

Despite the increasing popularity of endovascular intervention in clinical practice, there remains a lack of objective and quantitative metrics for skill evaluation of endovascular techniques. Data relating to the forces exerted during endovascular procedures and the behavioral patterns of endovascular clinicians is currently limited. This research proposes two platforms for measuring tool forces applied by operators and contact forces resulting from catheter–tissue interactions, as a means of providing accurate, objective metrics of operator skill within a realistic simulation environment. Operator manipulation patterns are compared across different experience levels performing various complex catheterization tasks, and different performance metrics relating to tool forces, catheter motion dynamics, and forces exerted on the vasculature are extracted. The results depict significant differences between the two experience groups in their force and motion patterns across different phases of the procedures, with support vector machine (SVM) classification showing cross-validation accuracies as high as 90% between the two skill levels. This is the first robust study, validated across a large pool of endovascular specialists, to present objective measures of endovascular skill based on exerted forces. The study also provides significant insights into the design of optimized metrics for improved training and performance assessment of catheterization tasks.

“…In the future, particle image velocimetry experiments will be added to this system, for further research of these indicators and strain results. As shown in this research and previous studies , the development of new materials for human tissue modelling and simulation are also very important. These new materials can be integrated with the current modelling technologies for the development of new diagnosis technologies and quantitative analysis for human skills profiling.…”

“…As a result, the commercial surgical tools can be evaluated without any modifications in this in-vitro simulator, and this technique can also be used for force feedback for robotic mechanisms [13,14]. The average stress information and image area with a large stress threshold during the operation process can be calculated and recorded for the evaluations of surgeons skills [11].…”

This paper presents a new in-vitro simulator that can simulate the new technology of three-dimensional digital subtraction angiography (DSA) to perform a cerebral aneurysm surgery. Then, propose a new technique for the numerical evaluation of the surgical tools applied within this interventional surgery to aid in the design and selection of surgical instruments. Initially, the in-vitro intravascular simulator was constructed, followed by cerebral aneurysm models that were fabricated with highly sensitive photoelastic materials of epoxy resin. Then reconstruct virtual reality modeling of the blood vessel and catheter to record the position information and realize virtual guidance for training. Meanwhile, conduct image processing of photoelastic effects for numerical evaluations of surgical instruments such as catheter insertion and stent expansion. During the stent expansion experiment, the average stress in the selected region of interest caused by the expansion was calculated and compared with the corresponding value obtained before the expansion. The presented simulator and measurement technique can assist in improving a surgeons skills, quantifying the performance of medical mechanisms, and contribute to 3D analysis of stress distribution. This approach can also provide feedback control for robot assisted endovascular systems.
