ABSTRACT
Though several simulators and training methods are available for basic laparoscopic skills, few have addressed force-based skills. In this work, we discuss a haptic simulator that renders virtual materials of different stiffness profiles to be used for haptic skills differentiation. A force-based task was designed on the simulator and the performance of surgeons and novices was analyzed. Results indicate that surgeons and novices differ in their ability to use the haptic device to reproduce target stiffness levels. This work provides an important step towards quantifying haptic skill metrics for the design of surgical skills training simulators.

In this work, we present four tasks, primarily testing haptic laparoscopic skill that can be simulated in a conventional box trainer. Results from examining expert surgeon and novice performance is presented as evidence that these tasks can be used for training haptic skills for laparoscopy in a box trainer.
