Vascular anastomosis training for neurosurgeons is carried out with various materials, with its pros and cons. PVA-H was chosen as the material for the human blood vessel model due to its lower surface friction and adjustable viscoelasticity properties. Several PVA-H variations were manufactured and compared with the help of neurosurgeons to determine the best PVA-H composition to represent human blood vessels. Blood-mimicking fluid (BMF) was also manufactured using a water-glycerin mixture to mimic the viscous characteristics of human blood. User interface and control unit were also developed to integrate blood vessel model and blood mimicking fluid with other components in medical phantom for vascular anastomosis, making sure that all components of anastomosis work well together as a unity. It was found that PVA-H/A10 was the best choice for a blood vessel model with a caliber of 2 mm whereas PVA-H/A15 was the best choice for a blood vessel model with a caliber of 3-4 mm. BMF with glycerin and water ratio of 60:40 with the viscosity was the best to represent human blood viscosity. Next, the user interface was developed by considering many aspects impacting user comfort. Lastly, the control unit was implemented using Python language arranged in MVC architecture to ensure the modularity and scalability of the program for the future development.
