Abstract :

Laparoscopy emerged as a revolutionary alternative to conventional laparotomy surgery from the 1990s, enabling complex procedures to be performed by inserting a camera and dedicated instruments through small incisions. This technical revolution has a real post-operative benefit for patients with shorter hospital stays and lower complication. Nevertheless, it brings discomfort for the surgeon, partly related to the loss of vision of the entire abdominal cavity and the appearance of blind zones that are visible in conventional open surgery.

To address this problem, we have developed a Global Vision System (GVS) to expand the field of view of laparoscopy and reduce blind areas within the Laboratory of Medical Engineering and Complexity (TIMC) , in Computer-Assisted Medical-Surgical Gestures Team (GMCAO). GVS is an innovative optical trocar on which 2 micro-cameras are deployed while allowing the insertion of the classic endoscope.

The benchmarking and preclinical evaluation of cadaveric and live pig models concluded that GVS allowed early detection of an adverse event without an increase in time to completion of the task or mental load. The proof of concept in real surgery condition could be demonstrated. The debriefings of the various experts were favorable and made it possible to identify the points of improvement necessary in the future. The maturation of the prototype on the security aspects, in particular electronic and sterilization, will make it possible to start the first tests in the human.
