New augmented reality visor offers benefits for surgeons

A new augmented reality surgical visor is being created by European scientists to give surgeons access to more information while carrying out operations.

The VOSTARS visor consists of a head-mounted display capable of superimposing X-ray images over the surgeon's view of the patient's anatomy, as well as anaesthetic data, heart rate, body temperature, blood pressure and breathing rates.

By keeping all of this information in the surgeon's view at all times, the need for the medical professional to look away is reduced, trimming surgery times by just over 20 minutes for every three hours.

This equates to a reduction in the time spent in an operation and under anaesthetic by at least 11 percent, while also enhancing the accuracy of the procedure itself, potentially resulting in better patient outcomes.

Project coordinator Dr Vincenzo Ferrari, a biomedical engineering researcher at the University of Pisa, said: "We intend to provide all the information required to improve surgery. The primary goal is to reduce not just surgery times, but also the time spent under anaesthetic and the cost involved in any operation."
