Area of Science:

  • Medical Simulation
  • Robotics and Control Systems
  • Surgical Training Technologies

Background:

  • Knee arthroscopy training traditionally relies on cadavers or animal models, which are costly and limited.
  • Existing virtual reality (VR) surgical simulators often lack realistic haptic feedback, hindering skill development.
  • The Warwick, Imperial, Sheffield Knee Arthroscopy Training System (WISHKATS) project aims to address these limitations.

Purpose of the Study:

  • To describe the initial development of an innovative haptic device for knee arthroscopy simulation.
  • To outline the engineering requirements for a compact, multi-degree-of-freedom motorised haptic mechanism with force sensing.
  • To integrate this haptic device into an existing VR training system for realistic diagnostic simulation.

Main Methods:

  • Development of a compact, multi-degree-of-freedom motorised haptic mechanism.
  • Integration of force sensors for realistic tactile feedback.
  • Software development to simulate tissue deformation during virtual knee arthroscopy.

Main Results:

  • The initial development phase of the WISHKATS haptic device has been successfully completed.
  • The device is designed to provide realistic force feedback on the probing tool.
  • The system simulates the diagnostic aspects of knee arthroscopy, including tissue deformation.

Conclusions:

  • The developed haptic device represents a significant advancement in VR surgical training for knee arthroscopy.
  • The WISHKATS system has the potential to enhance trainee skills through realistic simulation.
  • Further research into the engineering challenges and clinical validation of haptic systems is warranted.
