Haptics is the science and technology of experiencing and creating touch sensations in human operators. Because many medical interventions require physical contact between a patient and a caregiver, haptics plays an important role in the introduction of new medical technology. This talk will examine the role of haptics in medical robotics, including teleoperated robot-assisted surgery, models and simulations to enable training and planning of medical interventions, and rehabilitation. Robot-assisted surgery can improve the outcomes of medical procedures by enhancing accuracy and minimally invasive access, thereby reducing patient trauma and recovery time. With approaches ranging from psychophysical studies to control systems engineering, we have designed teleoperated robots capable of providing haptic feedback in challenging surgical environments. Haptic information is also needed for accurate medical simulation and planning. Surgical simulators present a safe and potentially effective method for surgical training, and can also be used in robot-assisted surgery for pre- and intra-operative planning. I will describe approaches to determine the mechanics of interaction between surgical instruments and tissues, and their application in simulation and robot-assisted interventions. Finally, rehabilitation through robotically enabled orthotics and prosthetics inherently requires understanding and appropriate generation of haptic interactions. Our recent work in this area includes motor control augmentation with an exoskeleton robot, and studies of the role of haptic proprioception in prosthetic limb use.
