Abstract
Abstract An endoscopic device having a handle assembly and a catheter assembly is disclosed. The catheter assembly carries a viewing conduit which cooperates with an eyepiece on the handle assembly for viewing in a patient's body cavity. The catheter assembly is preferably rotatably and removably mounted on the handle assembly. Also disclosed is a coupling unit which, together with the catheter assembly, forms an endoscopic camera device.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
166 words
An endoscopic viewing device comprising: (a) a handle assembly including an eyepiece, the handle assembly also defining a socket; (b) a flexible cannula having a proximal end and a distal end and defining a passageway and channel between the ends; (c) a plug mounted on the cannula proximal end and having a port in fluid communication with the channel; (d) a sleeve having a proximal end and a distal end and defining a bore between the ends, the sleeve being mounted on the plug with the bore in communication with the cannula passageway; (e) a flexible coherent fiberoptic viewing bundle received in the passageway and bore; (f) a flexible light transmitting fiber slidably received in the channel through the port; (g) locking means carried by the plug for fixing a portion of the light transmitting fiber with respect to the plug; and (h) retaining means for rotatably and releasably mounting the sleeve proximal end in the socket with the viewing bundle operably associated with the eyepiece.
Claim 2
Dependent Claim
