Currently available low cost haptic devices allow inexpensive surgical training with no risk to patients. Major
drawbacks of lower cost devices include limited maximum feedback force and the incapability to expose occurring
moments. Aim of this work was the design and implementation of a surgical simulator that allows the evaluation
of multi-sensory stimuli in order to overcome the occurring drawbacks.
The simulator was built following a modular architecture to allow flexible combinations and thorough evaluation
of different multi-sensory feedback modules. A Kirschner-Wire (K-Wire) tibial fracture fixation procedure
was defined and implemented as a first test scenario. A set of computational metrics has been derived from the
clinical requirements of the task to objectively assess the trainees performance during simulation.
Sensory feedback modules for haptic and visual feedback have been developed, each in a basic and additionally
in an enhanced form. First tests have shown that specific visual concepts can overcome some of the drawbacks
coming along with low cost haptic devices. The simulator, the metrics and the surgery scenario together represent
an important step towards a better understanding of the perception of multi-sensory feedback in complex surgical
training tasks. Field studies on top of the architecture can open the way to risk-less and inexpensive surgical
simulations that can keep up with traditional surgical training.
