Titan Medical out of Toronto, Canada has unveiled a new prototype minimally invasive surgical robot, the Single Port Orifice Robotic Technology (SPORT) Surgical System. The system works via a 25 mm single access port which contains two articulating instruments and a 3D HD camera. When the port is positioned within the incision to the abdomen, the camera and instruments can then extend into the cavity. Much like the famous da Vinci robotic system from Intuitive Surgical, the SPORT is operated by the surgeon through a special nearby console.
