ABSTRACT:
The elongated, hollow, thin-walled metal shaft of an operation endoscope is lined internally throughout its length by a separate thin-walled sleeve of electrical insulating material, the shaft and sleeve being mounted removably on a common head independently of each other in such manner that they are separable by relative longitudinal movement in the direction by which the sleeve is retracted rearwardly relative to the shaft, thereby affording retraction and replacement of the sleeve without removing the shaft from the operation site.
