Abstract
An endoscope has a handle portion and a separate shaft portion which can be joined to the handle portion. The shaft portion has a flexible shaft flexing movement of which is controlled by knobs on the handle portion, and this motion is transmitted across the handle/shaft interface by meshing gearwheels. Each tooth of each gearwheel has a crown shaped so as to have a central ridge between sloping sides which facilitate interengagement of the gearwheels when the latter are brought into crown-to-crown engagement in a non-rotating condition.
