    Toward Patient-Specific 3D-Printed Robotic Systems for Surgical Interventions
    (IEEE, 2019) Desai, Jaydev P.; Sheng, Jun; Cheng, Shing Shin; Wang, Xuefeng; Deaton, Nancy J.; Rahman, Nahian; Georgia Institute of Technology; Chinese University of Hong Kong; University of Alabama Tuscaloosa
    Surgical robots have been extensively researched for a wide range of surgical procedures due to the advantages of improved precision, sensing capabilities, motion scaling, and tremor reduction, to name a few. Though the underlying disease condition or pathology may be the same across patients, the intervention approach to treat the condition can vary significantly across patients. This is especially true for endovascular interventions, where each case brings forth its own challenges. Hence, it is critical to develop patient-specific surgical robotic systems to maximize the benefits of robot-assisted surgery. Manufacturing patient-specific robots can be challenging for complex procedures and, furthermore, the time required to build them can be a challenge. To overcome this challenge, additive manufacturing, namely, 3D-printing, is a promising solution. 3D-printing enables fabrication of complex parts precisely and efficiently. Although 3D-printing techniques have been researched for general medical applications, patient-specific surgical robots are currently in their infancy. After reviewing the state-of-the-art in 3D-printed surgical robots, this article discusses 3D-printing techniques that could potentially satisfy the stringent requirements for surgical interventions. We also present the accomplishments in our group in developing 3D-printed surgical robots for neurosurgical and cardiovascular interventions. Finally, we discuss the challenges in developing 3D-printed surgical robots and provide our perspectives on future research directions.
