Surgery by Satellite Offers New Possibilities at Medicine’s Cutting Edge

June 7, 2007 - Robots may soon be coming to your town, and your hospital. According to The International Journal of Medical Robotics and Computer Assisted Surgery, robots that perform surgery can be driven by surgeons who no longer stand by the patient, but direct the operation from a computer console.

In most cases the surgeon is seated at a console within the theatre, only a few feet away from the patient. Now a team of surgeons and scientists have shown that the surgeon and robot can be linked via a 4,000 mile Internet connection or by satellite.

In theory there is no reason why the surgeon needs to be physically close to their patient, so long as the communication link between the console and the robotic device is fast. The problem is that there may be too much of a delay between the image of the patient being captured and being displayed on the console, or between the surgeon sending an instruction and the robot responding.

A team of 11 researchers, who work jointly in the Department of Medical Biophysics, The University of Western Ontario, London, Ontario, and CSTAR(Canadian Surgical Technologies & Advanced Robotics), London Health Sciences Centre, London, Ontario, Canada, set out to test whether it is possible to link the surgeon and robot by the Internet and by satellite.

Their experimental surgical trials showed that the delays were much greater when they used the satellite link than using the Internet. However, after a short period of practice, the surgeon became used to this and there were no measurable differences in the quality of the surgery using the two forms of communication. The team thinks that virtual reality prediction would also greatly aid this type of surgery.

This is an exciting next step forward in developing telesurgery, which holds the promise of many new efficient and cost-effective ways of providing advanced healthcare services,” said project leader Reiza Rayman.
