Magnetic Soft Continuum Robots (MSCR) are used in a wide variety of surgical interventions, including neurological, pancreatic, and cardiovascular procedures. To function effectively, these MSCRs require complex programmable magnetisation. However, they often suffer from limited manoeuvrability and
We present a transformable catheter head structure for endoscopic catheter allowing the simultaneous use of a camera module and a large tool channel introduced through a small incision. At the site of interest, the head with a camera can be expanded from the initial straight configuration, which ope…
In this paper, we present the design of a steerable needle with proximal notch patterns for compliance and an embedded rotational tip joint for articulation. The device is fabricated by laser machining NiTi tube so that an inner working channel exists (to enable delivery of fluids, drugs or microtoo…
We present a medical-needle-sized robotic tube with multi-degrees of freedom (M-DOF) rotational hinge joints at the instrument tip, fabricated by two-axis laser micro-machining. Due to the presence of an ample working channel and direct tip controllability, this tube is a potential candidate for the…
Kinematic models of concentric tube robots have matured from considering only tube bending to considering tube twisting as well as external loading. While these models have been demonstrated to approximate actual behavior, modeling error can be significant for medical applications that often call fo…
