Area of Science:

  • Robotics
  • Biomedical Engineering
  • Surgical Instrumentation

Background:

  • Existing tactile sensors for RMIS struggle with accuracy when the probe is not perpendicular to the tissue.
  • Limited degrees of freedom (DOF) in surgical instruments necessitate sensors adaptable to various contact angles.

Purpose of the Study:

  • To propose a piezoelectric tactile sensor capable of detecting tissue stiffness irrespective of the contact angle.
  • To enhance the accuracy and reliability of stiffness detection in RMIS, particularly in scenarios with limited DOF.

Main Methods:

  • Development of a novel detection model and sensor optimization techniques.
  • Analysis of the influence of contact angle on stiffness detection through sensor parameter design.
  • Validation using simulations and experiments with five distinct tissue stiffness samples.

Main Results:

  • The optimized sensor achieved 100% recognition accuracy within a 30° contact angle range in simulations.
  • Experimental results showed a 92% correct classification rate within a 45° contact angle range.
  • The sensor effectively distinguished between normal tissue and lumps, even those with similar stiffness.

Conclusions:

  • The proposed piezoelectric tactile sensor demonstrates high accuracy and adaptability for tissue stiffness detection in RMIS.
  • This sensor offers broad application prospects in the medical field, overcoming limitations of existing technologies.
