NASA and its Jet Propulsion Laboratory are working on developing an auxiliary endoscope, dubbed MARVEL (Multi-Angle and Rear Viewing Endoscopic tooL), an instrument that will function essentially as a dental mouth mirror designed for endosinus surgeries, as well as for skull base and neurosurgical procedures.
A conventional endoscope provides mostly a frontal view ? that is, a view along its longitudinal axis and, hence, along a straight line extending from an opening through which it is inserted. The MARVEL could be inserted through the same opening as that of the conventional endoscope, but could be adjusted to provide a view from almost any desired angle. The MARVEL camera image would be displayed, on the same monitor as that of the conventional endoscopic image, as an inset within the conventional endoscopic image. For example, while viewing a tumor from the front in the conventional endoscopic image, the surgeon could simultaneously view the tumor from the side or the rear in the MARVEL image, and could thereby gain additional visual cues that would aid in precise three-dimensional positioning of surgical tools to excise the tumor. Indeed, a side or rear view through the MARVEL could be essential in a case in which the object of surgical interest was not visible from the front.
