In conventional brain surgery, neurosurgeons can only use 2D medical images (CT, MRI) and clinical experience to plan the surgical path. It is difficult to confirm that the surgical path will not hit the cerebral artery or important nerves. The "Augmented Reality-Assisted 3D Brain Surgery Navigation System" provides a fusion of 3D cerebral artery and skull models for plan safe surgical path and positioning navigation. The surgeon wearing an AR glasses can intuitively observe the real-time relative location of the 3D cerebral artery and surgical instrument models projected into the patient＇s skull, thereby improving the safety and efficiency of brain surgery. The integrated 3D brain artery and head models can also be printed using 3D printing technology for surgery training and teaching. It can be expected that the augmented reality assisted 3D brain surgery navigation system will be an important technology and product for surgery and surgical teaching and training in the near future.

The AR assisted 3D navigation system for brain surgery provides fused 3D cerebral artery (neuron), lesions, and head models for planning safe surgical path and navigation. Then, the AR glasses can project and align the fused model with the patient’s head. By wearing an AR glasses, the surgeon can intuitively watch the patient and relative locations of the 3D models of cerebral arteries and surgical tools projected inside the patient＇s skull in real time, and thus avoid damaging cerebral arteries by surgical tools and promote operation safety and efficiency.

The navigation system for neurosurgery is already a necessary medical equipment for neurosurgery. With the rapid establishment of 5G facilities around the world, it is expected that AR will be integrated into the robotic surgical navigation system. Through the rapid and low-latency communication of 5G, multiple people with AR devices involving in remote surgery will be highly possible. According to the report of Grand View Research, the global surgical robot market in 2018 was 2.01 billion US dollars, and the annual CAGR by 2025 was 22.3%.
