Abstract

The endoscope is for surgical use and is fitted with the optics connected to a viewing head. The sheath can be orientated to the longitudinal axis by means of wires (14). The control head has a light source and an entry for a probe to pass down the sheath. The fibre optics image is returned (32) into a lens tube (6) for viewing. This tube is focused by a knob (35) at the side, a gear wheel (37) engaging a rack (38) to move it linearly. Coaxial with it, and underneath, is a larger knob (39) engaging a slide (43) each side.
