Computer Assisted Surgery (CAS) improves safety and accuracy but requires an operator. This study explores direct surgeon control via virtual keyboards or voice recognition to enhance the man-machine interface in orthopedic surgery.

Area of Science:

  • Medical Engineering
  • Computer-Aided Surgery
  • Orthopedic Surgery

Background:

  • Computer Assisted Surgery (CAS) systems are increasingly used in operating rooms, enhancing surgical safety and accuracy.
  • Current CAS systems necessitate a dedicated operator, hindering direct surgeon-machine communication.
  • The 'matching' or 'skeletal registration' process, linking virtual images to patients, is a critical but complex step often requiring extensive interaction.

Purpose of the Study:

  • To evaluate strategies for improving the man-machine interface in CAS.
  • To enable direct control of CAS systems by surgeons or existing OR personnel.
  • To reduce reliance on specialized system engineers in the operating room.

Main Methods:

  • Investigated a CAS control panel (virtual keyboard) integrated into the navigation system.

Related Experiment Videos

  • Explored the implementation of a commercial voice-recognition system for CAS control.
  • Implemented and clinically evaluated these strategies in an orthopedic surgery setting.

    • Main Results:

    • The study reports on the implementation and clinical experience with new man-machine interface strategies for CAS.
    • Findings focus on facilitating direct surgeon control, addressing the complexity of the matching process.
    • The research details the integration of virtual keyboards and voice recognition within an existing CAS setup.

    Conclusions:

    • Improving the man-machine interface is crucial for efficient CAS implementation.
    • Direct surgeon control through virtual keyboards or voice recognition can streamline CAS operations.
    • These strategies aim to reduce healthcare costs and enhance surgical workflow in computer-assisted orthopedic surgery.
