Robot-assisted minimally invasive surgical (MIS) techniques offer improved instrument precision and dexterity, reduced patient trauma risk, promise to lessen the skill gap among surgeons. These approaches are common in general surgery, urology, gynecology. However, MIS remain largely absent for applications within narrow, confined workspaces, such as neuroendoscopy. The limitation stems from a lack of small yet dexterous robotic tools. In this work, we present first instance robot with...
Magnetic torsion springs are capable of producing unique and useful torque-displacement responses that not possible with elastic springs. Millimeter-scale magnetically-actuated robots, which gaining increasing interest in biomedical applications, would benefit from the use magnetic However, existing difficult to fabricate at scale can only produce sinusoid-like responses. Here we show magnets embedded links a robot for actuation purposes also be leveraged spring-like behavior. This...
Miniature magnetic tools have the potential to enable minimally invasive surgical techniques be applied space-restricted procedures in areas such as neurosurgery. However, typical navigation systems, which create fields drive tools, either cannot generate large enough fields, or surround patient a way that obstructs surgeon access patient. This paper introduces design of system with eight electromagnets arranged completely under operating table, endow maximal workspace accessibility, allows...
