Abstract

See full text

The foregoing application describes a system and method of performing a minimally invasive surgical operation. More specifically, the invention involves the use of disposable cannula and slender dilators of variable lengths, which incorporate a source of illumination to carry light to a surgical site and video capabilities for capturing and displaying images from a CMOS or CCD camera device. According to one embodiment, fiber optics run semi-circumferentially or along walls of the cannula/dilator and terminate at about a centimeter from the distal end of the cannula/dilator, thereby preventing illumination from “bottoming out” at the floor of the incision. According to one alternate embodiment, the light fibers may be fashioned in an annulus around one or more camera chips to provide illumination and video of the surgical site. In still another embodiment, the light fibers may be replaced by light emitting diodes in a more remote light source or alternatively at the distal-tip of the CMOS or CCD camera device.
