Surgical robots have captured the interest—if not the widespread acceptance—of spinal neurosurgeons. But successful innovation, scientific or commercial, requires the majority to adopt a new practice. “Faster, better, cheaper” products should in theory conquer the market, but often fail. The psychology of change is complex, and the “follow the leader” mentality, common in the field today, lends little trust to the process of disseminating new technology. Beyond product quality, timing has proven to be a key factor in the inception, design, and execution of new technologies. Although the first robotic surgery was performed in 1985, scant progress was seen until the era of minimally invasive surgery. This movement increased neurosurgeons’ dependence on navigation and fluoroscopy, intensifying the drive for enhanced precision. Outside the field of medicine, various technology companies have made great progress in popularizing co-robots (“cobots”), augmented reality, and processor chips. This has helped to ease practicing surgeons into familiarity with and acceptance of these technologies. The adoption among neurosurgeons in training is a “follow the leader” phenomenon, wherein new surgeons tend to adopt the technology used during residency. In neurosurgery today, robots are limited to computers functioning between the surgeon and patient. Their functions are confined to establishing a trajectory for navigation, with task execution solely in the surgeon’s hands. In this review, the authors discuss significant untapped technologies waiting to be used for more meaningful applications. They explore the history and current manifestations of various modern technologies, and project what innovations may lie ahead.

“…But the surgeons cannot use it as a navigation tool during the operation because simulation can only be performed on the computer. Sensory haptic feedback is also different from the real clipping [9][10][11]. 3D printing technology has important application value in the diagnosis and treatment of aneurysm especially in preoperative surgical rehearsal and neurosurgical training [12][13][14][15].…”

Background: The development of three-dimensional (3D) printing technology provides a new method for surgical treatment, but currently there are few reports on its application in the treatment of aneurysm. The aim of the present study was to explore the materials and methods of fabricating 3D printed individual aneurysm model and its value in the treatment of intracranial aneurysm. Methods: Twenty-four patients with intracranial aneurysm diagnosed by CTA who had undergone operation in our hospital were analyzed retrospectively. CTA Data collected at the time of surgery was used for reconstruction. Soft Mimics 17.0 was used to reconstruct the thin layer CTA scan data into 3D image and the final data was sent to the 3D printer for fabricating the model. We compared the proposed 3D printed model-based preoperative plan and the actual approach used in the surgery based on CTA data to evaluate the value of the 3D printed model in preoperative planning, and picked out the materials which were more suitable for the clinic. Results: Twenty-four aneurysm models with high degree of reality were fabricated successfully with 3D-printing technology. The patients' blood vessels, skulls and aneurysms were printed into the reality model at a ratio of 1:1. It is reported that the soft material-based, 3D printed vascular and aneurysm model more closely resembled the characteristics of the real blood vessels, thus provides a better simulation compared to the plaster-based model. Compared with the original operation plan, 3D printed model could be used for pre-operative aneurysm clip selection, and provide more intuitive information in selection of operational approach. Conclusions: 3D printed model can be used as an operational physical model to design operative schemes, choose the best operative paths and select suitable aneurysm clips by its high simulation degree and individualized characteristics. The model is helpful for surgical planning, especially for the preoperative plan of treating refractory multiple aneurysms and giant aneurysms.

Abstract. With the development of computer technology, the virtual reality technology has become more and more widely used in military field. The training of high-tech ammunition has the problems of low efficiency, high cost, poor security and inconsistent working mechanism. This paper fully analyzes the construction objectives and main contents of the high-tech ammunition virtual training, and applies virtual reality technology and Vega Prime to achieve the simulation of the process of a rocket weapon system to combat the target. This paper also makes further research on the technology of rocket trajectory calculation, real-time collision detection, etc., and achieves the whole process of combat simulation of the weapon system. The establishment of the system opened a new dimension of the military ammunition combat training .
