Area of Science:

  • Robotics and Control Systems
  • Biomedical Engineering
  • Medical Device Technology

Background:

  • Percutaneous puncture with flexible needles offers low trauma and maneuverability.
  • Clinical challenges include ensuring accuracy and avoiding obstacles during flexible needle insertion.
  • Developing effective path planning methods is crucial for advancing flexible needle applications.

Purpose of the Study:

  • To investigate the bending deformation laws of flexible needles during puncture.
  • To develop and validate a path planning method for accurate flexible needle insertion.
  • To provide a feasible approach for the clinical application of flexible needles.

Main Methods:

  • Modeled flexible needle paths as circular arcs, studying arc radius calculation.
  • Employed puncture experiments to determine actual arc radius values.
  • Utilized spatial transformation for 3D path planning and simplified particle swarm optimization (PSO) to adjust needle trajectory.

Main Results:

  • Flexible needle path radius is influenced by needle diameter, tip angle, puncture speed, and material properties (gelatin ratio).
  • Increased needle diameter and tip angle led to a larger path radius.
  • Higher puncture speed and gelatin ratio resulted in a smaller path radius, with tip accuracy of 1.8 mm in obstacle experiments.

Conclusions:

  • Successfully integrated intelligent algorithms (PSO) with flexible needle puncture for enhanced clinical utility.
  • Demonstrated that precise boundary conditions and parameter settings enable accurate target point mencapai for flexible needles.
  • The developed method holds significant potential for future clinical applications requiring precise flexible needle insertion.
