New  Interfaces  for  minimally  invasive  surgery:  allow  each  surgeon  to  operate  through laparoscopy as easily as through laparotomy.

Operating rooms integrate more and more technical devices: imaging, navigation, instruments (bipolar, monopolar, ultrasound, laser, etc.), robotics, etc.
During laparoscopic procedures, the installation of the various devices plus the constraints related to the uses of trocars have a considerable impact on the surgeon’s skills:

• The posture of the surgeon is uncomfortable and leads to postural fatigue.
• Visual space (screen) and manipulation space (instruments) are disjointed making hand-eye coordination difficult.
• The insertion of instruments through trocars induces a well-known phenomenon of “fulcrum effect” in the transmission of movements. An equivalent phenomenon occurs for effort and becomes crucial for force feedback devices.
• The perception of depth is degraded.

As a result, minimally invasive surgery is underused in clinical practice despite its undeniable medical benefits over open surgery. In this project, we propose to work to facilitate gestures in minimally invasive surgery by addressing more particularly the questions of interfaces and human-machine interactions.

Can we overcome the shortcomings of MIS without separating the surgeon from the team and the patient ?
