The Integrated Remote Neurosurgical System IRNS is a robotic neurosurgical microscope remotely-operated through the utilization of high-speed communications and a surgeon-accessible computer interface. The intended use of this system is for surgical mentoring of an operating-room OR surgical team by a remote expert surgeon. In the design of the IRNS, we emphasized giving the remote surgeon the feeling of actually being in the OR, a sense of telepresence, through the use of bidirectional audio, video whiteboarding on the microscope view, site cameras, voice recognition, bilateral access to the patients images and an interface to our presurgical planning software. The IRNS also includes several methods to control the remote microscope and its functions including rotation, translation, focus, and zoom. Safety precautions are implemented including the condition that any remote manipulation of the scope is possible only when the local operator actively permits it by holding down a dead man switch. The remote and local OR sites are integrated using an asynchronous transfer mode ATM switched network link. The development of the IRNS has provided an opportunity to assess the benefits of remote surgical mentoring and to gain technical expertise in the area of teleoperation of surgical devices over switched networks.
