Restoring surgeons’ sense of touch during minimally invasive surgeries

October 16, 2013 10:11 am | by David Salisbury, Vanderbilt Univ. | News | Comments

During open surgery, doctors rely on their sense of touch to identify anatomical structures: a procedure they call palpation. But this practice is not possible in minimally invasive surgery where surgeons work with small, specialized tools and miniature cameras. A small, wireless capsule has been developed that can restore the sense of touch that surgeons are losing as they shift increasingly from open to minimally invasive surgery.
