The surgical device could simulate the real operation environment and practice facilitating the surgical education as well as the hands-on trainings 8, 9. To address the challenge, learners could utilize a medical simulator with proper tactile feedback that offers a risk-free environment for them to be engaged in surgical practices and polish skills. Usually, a five-to-seven-year general neurosurgery training plus a one-to-two-year specialized cerebrovascular training is a basic requirement for most cerebrovascular neurosurgeons. However, the complex vascular network that neighboring the aneurysm does pose a thorny challenge to the 3D structure visualization in this method, which certainly requires a lot of training as well as sufficient experience. The cerebral angiography constructs a mental three dimensional images through combining a number of two dimensional images in the brain. To obtain such an understanding, cerebral angiography used to the only accessible approach for most cerebrovascular neurosurgeons. For operating cerebral aneurysm surgery, a prerequisite for a cerebrovascular neurosurgeon is a comprehensive understanding of the shape of aneurysm as well as its positional relationship with the cranial nerves, aorta and branches, brain, skull, etcetera 2. It is always a neurosurgeon, an expert of cerebrovascular disease, that handles the surgical clipping of a cerebral aneurysm, but the neurosurgical residents are seldom offered with chances to perform and learn from surgeries in spite of the long-lasting demand for aneurysm clipping as well as the high risks related to opening neurovascular surgery.
Patients and their attending surgeons are faced with a tough challenge in managing ruptured or un-ruptured cerebral aneurysms. Therefore, the demand for developing various efficient and safe surgical training methods has risen under such a circumstance 7. According to some studies, cerebrovascular neurosurgeons still prefer surgical clipping to treat specific aneurysms 4, 5, 6 depending on lesion morphology, their size and location. After the publication of ISAT study 3, an increasing number of patients has received the endovascular treatment of aneurysms. The treatment for cerebral aneurysms is usually secured with coils or clips to prevent re-rupture, which is a ubiquitously-accepted approach. Permanent nerve damage, hemorrhagic stroke or even death are all serious complications that could be seen in the cases of aneurysmal rupture whose mortality could reach 45% 2. Every year, the number of those who suffer from a ruptured cerebral aneurysm is approximately 10 in every 100,000 persons, while those who may have an un-ruptured cerebral aneurysm take up as high as 5 percent of the American population 1.
