Endoscopic device
First Claim
1. An endoscopic device for viewing internal parts of a body, comprising:
- an endoscope comprising;
(a) a rigid elongated tube having a proximal and a distal end;
(b) a control body attached to the proximal end of the elongated tube;
(c) an ocular eyepiece attached to the control body, said eyepiece adapted to permit viewing through the device to the distal end;
(d) a flexible fiber optic tip with a lens attached to the distal end of the rigid elongated tube;
(e) means for adjusting the position of the flexible fiber optic tip; and
a cannula having a proximal end, a distal end, an outer circumference and an inner circumference, and adapted to receive the endoscope, comprising;
(a) a hollow tube;
(b) means for moving the endoscope within said cannula between a cannula-extended position and a cannula-retracted position; and
(c) means for locking and unlocking the endoscope in the cannula-extended position and the cannula-retracted position,wherein in the cannula-extended position, the flexible tip is disposed entirely within the cannula and in the cannula-retracted position, the flexible tip extends beyond the distal end of the cannula.

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.

6. A cannula for positioning a flexible-tipped endoscope comprising:
-
a hollow tube; means for locking and unlocking the endoscope in two positions within the cannula, said first position being defined when the flexible tip of the endoscope is located entirely within the cannula, and said second position being defined when the flexible tip of the endoscope extends beyond the cannula. - View Dependent Claims (7, 8, 9)
