16. In an endoscope having a control handle unit and a separable, disposable, flexible shaft unit, a method for making the disposable unit articulable while preserving the disposable character of the shaft unit comprising:
-
providing a control handle unit; providing a disposable, flexible shaft unit separable from said control handle unit, placing shaft flexure means in the shaft unit, placing power means in the control handle unit for driving the shaft flexure means, and, positioning the power means and the shaft flexure means in their respective units so that when the units are connected the power means contacts the flexure means whereby operation of the power means is effective to drive the shaft flexure means. - View Dependent Claims (17, 18)
