1. A method of accessing and viewing a surgical field within the brain, said method comprising the steps of:
providing a cannula system comprising a cannula and camera assembly, the cannula comprising a cannula tube with a proximal end and a distal end and a lumen extending from the proximal end to the distal end, the camera assembly comprising an imaging sensor and a lens and a prism;
inserting the cannula with an obturator having a tip into the patient's brain until the distal end of the cannula and obturator tip is close to the surgical field;
removing the obturator so that the cannula can be used to provide access, illumination and visibility for the surgical field while the camera assembly remains in place;
positioning the camera assembly so that the camera assembly is secured to the proximal end of the cannula, with a portion of the camera assembly overhanging the lumen and extending into a cylindrical space defined by the lumen of the cannula tube; and
operating the camera assembly to obtain images of the surgical field obtained through the lumen.
