Sliding-Based Switching Control for Image-Guided Needle Steering in Soft Tissue

RA-L 2016

This letter represents a sliding-based controller for steering beveled-tip needles to stationary locations in soft tissue in a 2-D environment by performing appropriate switches of bevel orientation by 180° axial rotations while the needle is being inserted. Assuming the rotation velocity to be larg

A mechanics-based model for simulation and control of flexible needle insertion in soft tissue

ICRA 2015poster

In needle-based medical procedures, beveled-tip flexible needles are steered inside soft tissue with the aim of reaching pre-defined target locations. The efficiency of needle-based interventions depends on accurate control of the needle tip. This paper presents a comprehensive mechanics-based model…

Extended bicycle model for needle steering in soft tissue

IROS 2015poster

This paper represents an extension to the kinematic bicycle model for beveled-tip needle motion in soft tissue, which accounts for non-constant curvature paths for the needle tip. For a tissue that is not stiff relative to the needle, the tissue deformation caused by needle insertion deviates the ne…
