Abstract
A device for coupling a rigid surgical endoscope and a video camera has a compact, lightweight configuration which receives the endoscope without the conventional bulky endoscope eyepiece. The coupler has front and rear sections rotatable with respect to each other under a frictional drag to enable the endoscope and camera to be rotated either in unison or with respect to each other, so as to change the field of view of the endoscope or to change the orientation of the image on the screen of a video monitor, or both. The device includes sealing means to prevent fogging of the optics while enabling complete immersion of the endoscope, coupler and video camera, as a unit, in suitable liquid sterilization bath. The coupler also is adapted to accept endoscopes of various configurations.
