Preliminary Experiment of the Interactive Registration of a Trocar for Thoracoscopy with HoloLens Headset
Résumé
During surgical procedures, it may be necessary to insert one or several trocars between the patient’s ribs. This is the case, for example, with mini-invasive cardiac surgery to replace one or several heart valves assisted by 3D thoracoscopy: a trocar must be inserted before the camera is introduced. Most systems that provide visual assistance are complex and expensive. They are based either on robotics or magnetic tracking, and allow to track a precise positioning of surgical instruments and to provide an augmented visualization on a screen inside the operating room. Nevertheless, few operating rooms for this type of intervention own this type of hardware and most surgeons place and insert a trocar without visual assistance. In this paper, we have proposed a first software prototype of trocar guidance which exploits the mixed reality framework through the use of the Microsoft HoloLens headset. The surgeon first defines the position and direction of insertion using the CT scan in order to minimize the risk of damaging the patient’s internal organs during the trocar insertion then an interactive registration may help him or her during the intervention. In this article, we describe the sequence of computing steps and the first obtained results about such kind of interactive registration.
