Abstract
An adaptor for coupling an endoscopic probe to a video processor for displaying a picture of a target upon a viewing screen. The probe contains an optical element at its proximal end for providing an image of the target. A camming mechanism is used to secure the proximal end of the probe in one end of the adaptor housing. A small camera having a solid state in an insertion barrel is attached to the adaptor housing by sliding the lens barrel into a receiving opening formed in the opposite end of the housing. A chamber separates the distal end of the lens barrel and the proximal end of the probe. The targeted image presented by the optical element of the probe is recorded upon an imager mounted in the camera lens barrel and transmitted to the processor for viewing on the screen. The lens barrel is held within the adaptor housing by a detent mechanism having a ball that engages a groove formed in the lens barrel. A hollow stud having an axial bore is threaded into the adaptor housing so that the stud passes into the ball seat. A spring is contained within the bore which urges the ball into engagement with the lens barrel. An air passage connects the bore of the stud with the chamber separating the camera lens barrel and the probe whereby any moisture accumulating within the chamber is drawn out of the adaptor housing by applying suction to the stud.
