ABSTRACT:
An articulation mechanism for an endoscope wherein the endoscope has a generally elongated shaft and cables extending between a control head located at the proximal end thereof and an objective assembly located at the distal end thereof wherein the objective assembly is capable of being deflected over an arcuate co-planar path by the articulation mechanism is shown. The articulation mechanism comprises a proximal ring having a first outer edge and a second outer edge and the proximal ring is operative coupled to the distal end of the endoscope at one of the first outer ring and second outer ring and having a coupling member defined on the other of the first outer ring and second outer ring. A central ring having a first outer edge and a second outer edge, each of which defines an actuation member, is operatively connected by one of the actuation members to the coupling member. A distal ring having a first outer edge defining a coupling member a second outer edge wherein the second coupling member is operatively coupled to and which cooperates with the other of the actuation members. The central ring and the distal ring are operatively coupled to the cables and are responsive to the direction of movement of the cables to sweep the objective assembly over an arcuate co-planar path defined by a first predetermined angular path and a second predetermined angular path.
