Evaluation of robotic needle steering in ex vivo tissue
Abstract— Insertion velocity, tip asymmetry, and shaft diameter may influence steerable needle insertion paths in soft tissue. In this paper we examine the effects of these vari...

Design Considerations for Robotic Needle Steering
— Many medical procedures involve the use of needles, but targeting accuracy can be limited due to obstacles in the needle’s path, shifts in target position caused by tissue de...

Observations and models for needle-tissue interactions
— The asymmetry of a bevel-tip needle results in the needle naturally bending when it is inserted into soft tissue. In this study we present a mechanics-based model that calculat...

Nonholonomic Modeling of Needle Steering
As a flexible needle with a bevel tip is pushed through soft tissue, the asymmetry of the tip causes the needle to bend. We propose that, by using nonholonomic kinematics, contro...
