    Area of Science:

    • Medical Simulation
    • Haptic Rendering
    • Robotics

    Background:

    • Haptic simulation of needle insertion requires accurate needle-tissue interaction models and efficient rendering methods.
    • Existing rendering methods are often oversimplified or computationally intensive, limiting their practical application.

    Purpose of the Study:

    • To introduce the Generalized Tracking Wall (GTW) approach, a novel haptic rendering method for needle insertion simulation.
    • To accurately simulate needle-tissue interactions and force feedback without complex tissue deformation calculations.

    Main Methods:

    • The Generalized Tracking Wall (GTW) approach combines an energetic analysis of cutting with a contact model simulating viscoelasticity and nonlinearity.
    • The method is designed to replicate various phases of needle insertion, including multi-layered tissue scenarios.
