Area of Science:

  • Biomedical Engineering
  • Orthopedic Surgery
  • Materials Science

Background:

  • Drilling bone is a common surgical procedure.
  • Elevated temperatures during drilling can cause thermal necrosis and damage to bone tissue.
  • Predicting and mitigating heat generation is crucial for patient outcomes.

Purpose of the Study:

  • To develop a predictive model for heat generation during bone drilling.
  • To investigate the influence of various drilling parameters on temperature rise and thermal injury in bone.
  • To identify key factors affecting thermal damage during orthopedic drilling.

Main Methods:

  • Developed thermo-mechanical equations based on machining theory to model heat generation.
  • Coupled these equations with a finite element method (FEM) heat transfer simulation.

Related Experiment Videos

  • Performed a parametric analysis varying rotational speed, feed rate, drill geometry, and bone properties.

    • Main Results:

    • Drill rotational speed, feed rate, and drill diameter were identified as the most significant factors influencing temperature rise.
    • Changes in drill helix angle, point angle, and bone thermal properties had minimal impact on temperature.
    • The model successfully predicted temperature rise and potential thermal injury during bone drilling.

    Conclusions:

    • Optimizing drill speed, feed rate, and diameter is critical for minimizing thermal damage during bone drilling.
    • The developed thermo-mechanical model provides a valuable tool for predicting and managing thermal risks in orthopedic surgery.
    • Further research can refine the model by incorporating more complex bone properties and surgical scenarios.
