This study introduces a novel haptic device for simulating ventricular shunt insertion. The device enhances surgical training and planning by providing realistic force feedback.

Area of Science:

  • Neurosurgery
  • Medical Simulation
  • Robotics

Background:

  • Ventricular shunt insertion is a critical neurosurgical procedure.
  • Effective surgical training requires realistic simulation tools.
  • Existing simulators may lack adequate haptic feedback for complex procedures.

Purpose of the Study:

  • To develop and evaluate a new one-degree-of-freedom haptic device.
  • To enhance the BRAINTRAIN training simulator for neurological procedures.
  • To improve surgical planning and neuroscience education through realistic simulation.

Main Methods:

  • The haptic device utilizes a push-pull cable mechanism.
  • A linear motor generates forces transferred to a user-controlled end-effector.
  • An open-loop impedance algorithm controls the rendered forces up to 15 N.
