The invention discloses a whole-process vascular interventional operation training method and
system based on a
virtual reality technology, and the method comprises the steps: firstly, developing a vascular interventional
mechanics and collision
simulation module, and achieving the deformation
simulation of a
blood vessel and a guide wire through the combination of position dynamics, a region
shape matching technology and a Cosseerat elastic rod model, the collision between the
blood vessel and the guide wire is treated by adopting a wide-to-narrow three-layer progressive
collision detection method; secondly, constructing an immersive virtual operation scene through model construction and rendering optimization;
visual angle roaming, instrument operation and interface interaction are fused, and multi-mode
interaction control driving intervention training is achieved; finally, based on a'module-event 'dual-drive framework, operation tasks such as
anesthesia, puncture,
radiography, intervention,
stent release and
hemostasis are sequentially connected in series through a unified state
machine, and whole-
process training is achieved. The accuracy and stability of
blood vessel and guide wire
simulation are improved, the training immersion sense is enhanced, interventional operation whole-
process training is achieved, and high teaching and practical value is achieved.
