Khurshid Guru, MD, a staff physician in Urology at Roswell Park Cancer Institute (RPCI), and Thenkurussi "Kesh" Kesavadas, PhD, director of the Virtual Reality Laboratory and a professor of mechanical and aerospace engineering at the University at Buffalo (UB), created RoSS as a way to help surgeons hone their skills in robot-assisted surgery so that they've logged hours of training before they perform a particular surgical procedure. The HOST software system takes this concept further, immersing the surgeon in a surgical environment using automation technology and an interactive checklist-based process.
"It's as close to operating as you can get outside the operating room", stated Dr. Guru, who is also director of RPCI's Center for Robotic Surgery. "HOST literally holds the surgeon's hands."
The HOST software system takes surgeons through surgical steps, prompting and guiding them through the critical stages of an operation before proceeding to the next step. A metrics tool evaluates user performance so that surgeons can track their progress. That step-by-step prompting system is unique in the field of computer-assisted surgical learning tools, as is HOST's basis in observational learning. It's an extremely effective system for training surgeons on emerging robot-assisted surgical techniques, said Dr. Guru.
"Even though it uses these new computer-aided tools, our system is rooted in mentored, hands-on surgical training, just like the traditional training model", he stated. "They both come back to responding to cues and the opportunity to observe master surgeons."
"Building on our past collaborations", noted Dr. Kesavadas, "we developed a process for capturing the cognitive and motor skills of a trained surgeon and developed a virtual surgical experience for other surgeons to train on. This new system teaches the steps by guiding users in actually performing a surgery in tandem with the master surgeon - outside the operating room."
Dr. Kesavadas and researchers from the UB Virtual Reality Lab are experts in the development of haptic technologies that bring a sense of touch to virtual reality (VR). They have developed advanced VR applications for medical, surgical and educational applications.
At present, the HOST software system has been programmed to demonstrate two of the most common procedures within the field of robot-assisted surgery: prostatectomy and hysterectomy. Applications that would expand the HOST software for use in other types of surgeries are in development. "This concept, which we've been working on since 2007 at UB and Roswell Park, has been licensed to Simulated Surgical Systems LLC (SSS) and will be ready for implementation with RoSS by the end of the year", stated Dr. Kesavadas, Chief Technology Officer of the Williamsville, New York company. Dr. Guru is SSS' Chief Medical Officer.
The University at Buffalo is a premier research-intensive public university, a flagship institution in the State University of New York system and its largest and most comprehensive campus. UB's more than 28.000 students pursue their academic interests through more than 300 undergraduate, graduate and professional degree programmes. Founded in 1846, the University at Buffalo is a member of the Association of American Universities.
The mission of Roswell Park Cancer Institute (RPCI) is to understand, prevent and cure cancer. RPCI, founded in 1898, was one of the first cancer centers in the country to be named a National Cancer Institute-designated comprehensive cancer centre and remains the only facility with this designation in Upstate New York. The Institute is a member of the prestigious National Comprehensive Cancer Network, an alliance of the nation's major cancer centres; maintains affiliate sites; and is a partner in national and international collaborative programmes.
