Abstract
The invention is an endoscopic and cannula system for viewing internal parts of a human body, comprising an endoscope and a cannula. The endoscope comprises an elongated extension tube, which has, at its proximal end, a control body and, at its distal end, a flexible fiber optic tip. An ocular eyepiece is attached to the control body and is adapted to permit visualization through the endoscope to the area to be viewed. A manually controlled flexible fiber optic tip is attached to the distal end of the extension tube and has a lens attached to its distal end. The control body has knobs for adjusting the position and/or direction of the flexible fiber optic tip. The cannula comprises a hollow tube for receiving the endoscope and has means for moving the endoscope between a cannula-extended position and a cannula-retracted position. In the cannula-extended position, the flexible fiber optic tip is located entirely within the cannula, and in the cannula-retracted position, the manually controlled flexible fiber optic tip extends beyond the distal end of the cannula.
