The Virtual Temporal Bone simulator creates a true-to-life experience encountered in ear surgery. The temporal bone contains the structures for hearing and balance, and the simulator allows future surgeons to practice delicate surgical drilling techniques on a computer-based teaching system instead of cadavers or as apprenticeships in operating rooms. A multi-institutional validation study is now underway to determine if surgical residents taught by this simulator achieve better surgical results compared to traditional methods.
The system’s realism is enhanced with a SensAble PHANTOM® haptic device, which allows surgeons to “feel” the surgery they are performing, as well as see and hear it. SensAble’s device and accompanying software employ force-feedback technology to literally push back on the trainee’s hand as they look through a binocular viewer that replicates the view that a surgeon would see through a microscope during surgery. Drilling sounds are then modulated based upon the pressures and area of bone being removed.
In choosing the Netter Award, the selection committee commended the system’s “high production values, the incorporating of multiple sensory modalities – sight sound and touch - and the ease of distribution that make the Virtual Temporal Bone a unique learning object with tremendous potential impact in the field of medical education.”
“With SensAble’s technology in our system, surgeons are not only learning with their eyes, but also with their sense of touch,” said Don Stredney, director of the OSC Interface Lab and the project’s other lead investigator. Stredney also serves as an adjunct instructor in biomedical informatics and otolaryngology at The Ohio State University.
“SensAble’s Open Haptics software developers’ kit enabled us to easily integrate haptics into our application, and to provide a training environment that presents a safe, cost-effective way to learn fundamental techniques. This could be an important tool in the learning process for surgeons to develop all their senses in order to guide their surgery,” Stredney said.
“This team has built a very impressive virtual environment for surgical training, and we are pleased they have incorporated our PHANTOM haptic device into the solution,” said David Chen, PhD, and SensAble’s chief technology officer. “We are equally proud to see their work recognized by this award.”
The Virtual Temporal Bone Project is funded by the National Institute on Deafness and Other Communication Disorders, The National Institutes of Health.
