In neurosurgery, there is a method to clip an aneurysm which proliferates at a diverging point of arteries. It is very important for surgeons to train for improving their skills with simulators based on virtual reality technology. This paper describes an artery model with an anuerysm, which model can deform in real-time. In the surgery, doctors have to handle an instrument called spatula with a hand and clip the aneurysm with another hand. Usually, with computer graphics, one of virtual reality technology, the artery model is constructed with many polygons, which take a lot of time to calculate the collision detection between the polygons of the artery and that of the instrument. In this paper, the skelton of the model is used and the collision detection is performed between the skelton of the artery and that of the instrument. This model enabled the artery model with an aneurysm to deform in real-time and us to develop the neurosurgery simulator.
