Abstract
Although commercial telerobotic surgery systems such as the Intuitive da Vinci are approved for use on human patients, they provide the surgeon with very little touch feedback. Measuring and recreating tool-tissue interaction forces is technically challenging, especially while satisfying the safety and sterility requirements of surgery.
Kuchenbecker's research group at Penn has invented and studied two methods for adding tactile feedback to such systems. The first approach enables the surgeon to feel high-frequency instrument vibrations, which indicate important transitions in manipulation contact state that are often difficult to discern visually. They mount three-axis high-bandwidth accelerometers to the robot arms under the sterile draping; their outputs drive one-axis voice-coil actuators positioned on the surgeon hand controllers.
Recordings of live surgeries support the clinical feasibility of this approach. Other studies have demonstrated that surgeons significantly prefer this additional vibration feedback and that it has the potential to improve patient safety.
Their second approach to providing tactile feedback in telerobotic surgery centers on palpation, where the surgeon examines soft tissue using his or her fingertips. Working with the University of Siena, they mounted a biomimetic fingertip tactile sensor (SynTouch BioTac) to the end of a da Vinci instrument and attached a custom cutaneous display to the corresponding da Vinci master controller.
Using data recorded when the BioTac was inside the cutaneous display, their control algorithm finds the closest fingertip deformation experienced during calibration and drives the cutaneous display to the corresponding actuator outputs. A human-subject experiment with this system demonstrated that fingertip deformation feedback significantly improved the operator's ability to locate a rigid object embedded in soft simulated tissue.
Biography
Dr. Katherine Kuchenbecker is an associate professor in Mechanical Engineering & Applied Mechanics at the University of Pennsylvania. She is a member of the GRASP Lab, has a secondary appointment in Computer & Information Science, and is in the graduate groups of Bioengineering and Electrical & Systems Engineering. Her research centers on the design and control of haptic interfaces for applications such as robot-assisted surgery, medical simulation, stroke rehabilitation, and personal computing, as well as touch perception for autonomous robots.
Kuchenbecker has won several awards for her research, including an NSF CAREER Award in 2009 and the IEEE Robotics and Automation Society Academic Early Career Award in 2012. She gave a TEDYouth talk on haptics in 2012, and she received a Penn Lindback Award for Distinguished Teaching in 2014. Before becoming a professor, she completed a postdoctoral fellowship at the Johns Hopkins University, and she earned her PhD in Mechanical Engineering at Stanford University in 2006.
