Magnetic Fluid‐Driven Vine Robots for Minimally Invasive Tissue Biopsy Sampling

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a magnetic fluid‐powered vine robot for minimally invasive biopsies. The robot uses fluid pressurization for locomotion and external magnetic fields for precise steering. Its soft structure and high magnetic volume ensure controlled movements and stabilization, enabling effective tissue penetration.

Microscopic observations of needle and soft-tissue simulant interactions [PDF]

open access: yes, 2011
Currently, physicians have no means of correctly estimating the needle tip location during percutaneous needle insertion. A model of needle-tissue interaction that predicts the needle tip location would assist physicians in pre-operative planning and ...

Minimally Invasive Bowel Cancer Detection through Vibrating Microrobot‐Induced Elastography

open access: yesAdvanced Intelligent Systems, EarlyView.
A minimally invasive diagnostic method for bowel cancer detection combines vibrating microrobots and laser speckle contrast imaging to map tissue elasticity. By analyzing vibration‐induced resonance, detailed elasticity maps are produced, clearly differentiating tumors from healthy tissue.

Spatio-Temporal Deep Learning Models for Tip Force Estimation During Needle Insertion

open access: yes, 2019
Purpose. Precise placement of needles is a challenge in a number of clinical applications such as brachytherapy or biopsy. Forces acting at the needle cause tissue deformation and needle deflection which in turn may lead to misplacement or injury. Hence,
