Objective To explore the establishment method of virtual three-dimensional model of the virtual artery and interven-tional devices,and its application value.Methods The virtual models including virtual artery system,catheter,guide wire,stent and coil were established by using the three-dimensional moulding software of 3D Studio MAX R3.The study about interventional preoperative simulation and assistant instruction were run in personal computer.Results ①All the virtual instruments and real in-struments were highly similar shape,the arterial system in the visual display was similar to realistic system.②All arteries branches had own name,could be arbitrarily adjusted curvature,diameter and established the lesion morphology.③The reference value of preoperative simulation results to guide the actual surgery included following aspects:to guide the reasonable shaping of micro-cathe-ter and micro-guide wire tip,to plan the coil and stent deployment location,number and size.④In training and teaching,the preop-erative simulation could assist doctors in learning and remembering the artery branch and establishing the concept of three-dimen-sional space,and enhanceing the intention understanding of surgery.Conclusion The establishment method of virtual model of the virtual artery and interventional devices is reliable.The preoperative simulation results can be used to guide practical operation with relatively high accuracy,and it has an important supporting role for the teaching and training of medical students.
