Beating Hearts and Trembling Hands: Active and Passive Compensation of Biological Motion for Surgery

Cameron Riviere

Associate Research Professor

Robotics Institute, Carnegie Mellon University

Time and Place

Mauldin Auditorium (NSH 1305)
Refreshments 3:15 pm
Talk 3:30 pm

Abstract

Most of the research in the Medical Instrumentation Lab deals with suppression of quasi-periodic biological motion to enhance accuracy during surgical manipulation. This talk will cover two such projects: HeartLander, a miniature tethered mobile robot that passively compensates for heartbeat and respiratory motion during beating-heart surgery by grasping the heart surface using suction and moving with it as it beats, and

Micron, a handheld micromanipulator that actively compensates for the hand tremor of the surgeon in demanding specialties such as vitreoretinal microsurgery. The engineering rationale behind each project will be discussed, and recent experimental results will be presented. A third surgical project will also be addressed, dealing with steering of flexible needles for minimally invasive access to lesions deep in the brain.

Speaker Biography

Dr. Riviere received the Ph.D. in Mechanical Engineering from The Johns Hopkins University in 1995, and joined the Robotics Institute the same year. He received second place in the 1995 Whitaker Student Paper Competition of the IEEE Engineering in Medicine and Biology Society. Since 1997 he has also been an Adjunct Assistant Professor in the Department of Rehabilitation Science and Technology at the University of Pittsburgh.
