Abstract
An endoscope includes a first tube having a proximal end and distal end, a second tube having a proximal end and distal end, and a control rod movably coupled to the first tube and secured to the second tube for allowing the second tube to be rotated out of lengthwise alignment with and axially movable with respect to the first tube. The first tube includes concentrically disposed optical fibers with ends terminating at the distal end of the first tube. The second tube includes separate concentrically disposed optical fibers with ends terminating at both the proximal and distal ends of the second tube. When the first and second tubes are longitudinally aligned, at least some of the optical fibers in the second tube are substantially aligned with those in the first tube such that light is coupled therebetween. Both of the first and second tubes are capable of receiving imaging means.
