To overcome possible drawbacks of bone fracture reduction such as risks of malrotation, radiation exposure, as well as laborious traction, image-guided robotic surgery systems have been proposed. However, the use of optical tracking systems (OTS) creates inherent line-of-sight problems that cause fr
Notched compliant joints (NCJs) have been widely used in orthopedic surgeries requiring large curvatures for a minimally invasive approach to lesions and high rigidity for cutting hard tissues. With current NCJ designs, there is a trade-off between maximizing rigidity and maximizing curvature for a
End-effector type robots have been popularly applied to robot-aided therapy for rehabilitation purpose. However, those robots have a key drawback for the purpose: lack of the user's posture (joint angle) information. This letter proposes a novel end-effector rehabilitation robot system that contains
The remote center of motion (RCM) mechanism is a prominent candidate to aid bone drilling. The surgeon can simply place a drill with the RCM mechanism near the entry point to provide drill alignment with the target. Using this assistive mechanism for bone drilling improves drilling accuracy and redu…
