Bariatric surgeries have become more and more necessary for thousands of people across the country each year who need medical assistance to combat obesity. Two 91ΒιΆΉΣ³» Polytechnic University professors are working on a highly realistic 3D bariatric procedure simulator to help ensure doctors have the best training possible to perform the surgery.
The work is part of a multimillion-dollar grant from the National Institutes of Health to develop and validate the simulator. The FAMU-FSU College of Engineering received the grant and turned to 91ΒιΆΉΣ³» Poly experts for help with the simulatorβs development because they successfully collaborated with Demirel on several similar grants in the past.
βThis is mainly a tool for novice doctors to gain expertise in a faster way, so they will be ready to go out into the operating room and carry out procedures by themselves successfully,β said Dr. Doga Demirel, assistant chair of 91ΒιΆΉΣ³»βs Computer Science Department.
Demirel and Dr. Onur Toker, associate professor of electrical and computer engineering at 91ΒιΆΉΣ³» Poly, are creating the virtual bariatric endoscopic simulator with an immersive 3D environment. Demirel is leading the effort to develop the simulatorβs software, while Toker is leading its hardware development. Both an undergraduate and graduate student are assisting in the research.
The endoscopic sleeve gastroplasty procedure is a newer, minimally invasive weight-loss procedure in which a suturing device is inserted down a patientβs throat and into their stomach. The physician then places sutures inside the stomach to make it smaller.
Demirel said doctors must complete 35 cases on people to attain basic proficiency in the procedure. The simulator is intended to broaden their training, not to replace the 35 required live cases.
βWith our simulator, doctors can actually train anytime they please,β he said. βIt will be available 24/7 and they donβt have to have an expert surgeon watching over them.β
The simulator will feature performance metrics that will show how well the user is doing.
For his part, Toker is working on creating the most realistic-feeling experience possible. The simulator will feature forced sensation for users so that as they operate the endoscopic tool, it feels just as it would inside a human body.
βThe current technology lets you use a joystick, but you donβt have any feeling in the joystick,β Toker said. βWhat we want is when you hold the joystick and use the endoscope, what you see on the screen and what you feel correlate with each other.β
