Haptics in the news

“It always helps to be able to feel what you are doing, to feel the tissue
tension and to feel the force when manipulating a suture,” says Domenico
Savatta, chief of minimally invasive and robotic urology surgery at Newark
Beth Israel Medical Center. “Haptics would make it easier to learn robotic
surgery, operate on things that are very delicate, and be an overall
advantage to have in the system.”

Surgical Robots Get a Sense of Touch

This was a nice review in technology review, by Brittany Sauser.
I appreciate the chance to stress the importance of what haptics will mean to robotic surgery.
Currently I have learned to rely on a highly magnified image and what I call, “visual haptics”. Having a 10 times magnified image with a camera that is a few inches away from the surgical field allows me to see the tension in tissue. I await the day when I can combine the visual haptics with touch.
I learned from this article that the team at John Hopkins is working on a visual haptic system that has dots that can change colors as a marker of tension.
I remember reading about a system that worked on auditory haptics, where a sound would increase in intensity with increasing tension.
