In this paper, we describe our prototype of an ultrasound guidance system to address the need for an easy-to-use, cost-effective, and portable technology to improve ultrasound-guided procedures. The system consists of a lockable, articulating needle guide that attaches to an ultrasound probe and a user-interface that provides real-time visualization of the predicted needle trajectory overlaid on the...
We propose a new snake-like robot for use in single-port minimally invasive surgery. The snake robot is made of a concentric tube robot and a highly articulated robotic probe. The probe operates as a stiff shield for the concentric tube robot. Consequently, the snake robot provides simultaneously high tip stiffness and dexterity that cannot be obtained by the single use of any of two robots. A critical...
