The rapid proliferation of enabling technology into the clinical environment has changed the way health care is delivered to patients. Technology has revolutionised the way physicians do their work, using new instrumentations, techniques and procedures. For example, surgeons now perform surgery remotely and minimally invasively using endoscopic instruments and robotics. However, much of the development in endoscopic surgery, or minimally invasive surgery, has been technology-driven, with little consideration for human factors issues in design and implementation. As a result, higher workload and error rates have been documented. This has significant impact on patient outcome.

Navigation and Orientation in Endoscopy

The goals of this research focus are to understand the role of spatial information in navigation and orientation in a remote flexible environment, to design shape sensors for tracking flexible endoscopes and other medical devices, and to design a navigational aid display for the visualization of 3D position and orientation during endoscopic procedures, such as colonoscopy, bronchoscopy, etc.

Ongoing project:

  • Endoscopic Fiber Optic Shape Tracker (EFOST)

Remote Visualization and Manipulation in Endoscopy

The goals of this research focus are to understand the effects of disrupted visuomotor congruency and lack of haptics feedback on surgical performance in minimally invasive surgery, to design haptic interfaces, endoscopic tools and visualization systems for the remote manipulation of tissues during minimally invasive procedure, such as laparoscopic surgery or robotic surgery.

Ongoing projects:

  • Haptic Interface Design for Minimally Invasive Surgery
  • Telesurgery and Telemedicine
    (currently in development, more information will follow soon)

Surgical Skills Training

The goals of this research focus are to study surgical skills acquisition and retention of novice and expert surgeons, and to design real and virtual surgical skill simulators for endoscopic surgery.

Technology Assessment and Validation

The goal of this research focus is to evaluate and validate new designs of surgical training programmes and technology using the human-centered systems design approach.

Ongoing project:

  • Development & Validation of Virtual Basic Laparoscopic Surgical Trainer (VBLaST)
