Abstract
An endoscope insertion cannula assembly including an endoscope housing and axially projecting body having an endoscope tip. An adapter is affixed about the endoscope housing, and a guide is affixed about the adapter. A spring and a seal are also affixed about the adapter. The endoscope instrument, together with the associated adapter, spring and guide, are inserted into a cannula housing. A pin on the inside of the cannula housing interacts with an angled slot on the distal surface of the guide to rotate the endoscope instrument into its proper rotational orientation. A hole in a cam surface of the spring then receives the pin on the inside of the cannula housing to control the axial orientation of the tip of the endoscope instrument with respect to the tip of the cannula tube.
