Area of Science:

  • Biomedical Engineering
  • Medical Device Manufacturing
  • Orthopedic Surgery

Background:

  • Traditional Computer-Aided Design/Computer-Aided Manufacture (CADCAM) is typically associated with mass production.
  • The medical field, specifically Biomedical Engineering, requires the creation of unique, individualized implants rather than mass-produced items.

Purpose of the Study:

  • To adapt CADCAM technologies for the production of one-off, patient-specific medical implants.
  • To leverage CADCAM for the efficient design and manufacturing of custom implants for bone tumour cases and hip replacements.

Main Methods:

  • Utilizing a knowledge-based system to generate implant designs from X-ray data.
  • Employing modular component assembly to expedite implant production.
  • Applying CADCAM techniques to create custom hip replacements based on digitized radiographic data.
