  • A virtual surgical simulator for mandibular angle reduction based on patient specific data
    2012 IEEE Virtual Reality Workshops (VRW), 2012
    Co-Authors: Qiong Wang, Wen Wu, Hui Chen, Pheng-ann Heng
    Abstract:

    In our work, a virtual reality-based surgical simulator for the mandibular angle reduction was designed and implemented on CUDA-based platform. High-fidelity visual and haptic feedbacks between the surgical instruments and the bone material are provided to enhance the perception in a realistic virtual surgical environment. Impulse-based dynamics haptic model was employed to simulate the contact forces generated on the high-speed instruments, including the Reciprocating Saw and the round burr. The validity of the simulated contact forces was verified by comparing against the actual force data measured through the constructed mechanical platform. An empirical study based on the patient specified data was conducted to evaluate the ability of the proposed system in training surgeons with various experiences. The results confirm the validity of our simulator.

  • Real-time mandibular angle reduction surgical simulation with haptic rendering
    IEEE Transactions on Information Technology in Biomedicine, 2012
    Co-Authors: Qiong Wang, Hai-yang Jin, Wen Wu, Hui Chen, Pheng-ann Heng
    Abstract:

    Mandibular angle reduction is a popular and efficient procedure widely used to alter the facial contour. The primary surgical instruments, the Reciprocating Saw and the round burr, employed in the surgery have a common feature: operating at a high-speed. Generally, inexperienced surgeons need a long-time practice to learn how to minimize the risks caused by the uncontrolled contacts and cutting motions in manipulation of instruments with high-speed reciprocation or rotation. A virtual reality-based surgical simulator for the mandibular angle reduction was designed and implemented on a CUDA-based platform in this paper. High-fidelity visual and haptic feedbacks are provided to enhance the perception in a realistic virtual surgical environment. The impulse-based haptic models were employed to simulate the contact forces and torques on the instruments. It provides convincing haptic sensation for surgeons to control the instruments under different reciprocation or rotation velocities. The real-time methods for bone removal and reconstruction during surgical procedures have been proposed to support realistic visual feedbacks. The simulated contact forces were verified by comparing against the actual force data measured through the constructed mechanical platform. An empirical study based on the patient-specific data was conducted to evaluate the ability of the proposed system in training surgeons with various experiences. The results confirm the validity of our simulator.

  • visuohaptic bone Saw simulator combining vibrotactile and kinesthetic feedback
    International Conference on Computer Graphics and Interactive Techniques, 2015
    Co-Authors: Pontus Olsson, Andreas Thor, Fredrik Nysjo, Neeru Singh, Ingrid Carlbom
    Abstract:

    The combination of stereo visualization and haptics provides a natural interface for surgical training simulators, an application which is inherently both highly visual and highly tactile. However, most off-the-shelf kinesthetic haptic devices, such as the popular Phantom devices, are not well-suited to display high-fidelity vibrotactile feedback for the high frequency force components in surgical tools such as a Reciprocating bone Saw. In these haptic devices, forces are mediated from the actuators to the user through a mechanical linkage, in which inertia, friction, and backlash may distort the feedback. In addition, sustained display of vibrations may cause undue wear of the device. We propose a hybrid solution combining kinesthetic feedback from an off-the-shelf haptic device with high-fidelity vibration feedback from a vibrotactile actuator, and show that the hybrid is able to reproduce vibrations of an actual surgical Reciprocating Saw within the full perceptible frequency range.
