Summary/Abstract: Our goal is to develop a novel semi/autonomous, minimally-invasive, image-guided neurosurgical robotic workstation that consists of (i) a biomechanics-aware design and planning module, (ii) a robotic positioning mechanism integrated with a unique sensorized steerable drilling robot, and (iii) a novel flexible pedicle screw (FPS) to enable the next generation of minimally invasive spinal fixation interventions. In this workstation, a surgeon first uses Quantitative Computed Tomography (QCT) scans of a patient to map spatial bone mineral density of the vertebra and perform pre-operative biomechanical analysis and surgical planning. Next, they can intuitively and accurately control the developed steerable drilling robotic system via an autonomous or semi- autonomous mode to execute this plan in real-time and implant flexible pedicle screws in the drilled tunnels. By providing spatial access to the regions within vertebral body, which are not currently accessible utilizing conventional rigid surgical instruments, this neurosurgical robotic workstation enables the next generation of spinal fixation called Spatial Spinal Fixation (SSF) for various bone defects in spine such as compression on the spinal cord and/or nerve roots, metastatic bone disease, and vertebral compression fractures due to severe osteoporosis. Spinal fixation (SF) is one of the standard procedures performed by the spine and orthopedic surgeons. SF is an effective treatment option for a wide range of spinal disorders such as stabilization of vertebral compression fractures, scoliosis, and disk disease. Since the 1990s, rates of SF procedures in the United States have substantially increased. For example, over 500,000 SF operations were performed in 2018 in the US, with a mean patient age of 54.2 years and a mean cost of
