ABSTRACT:
An optical coupler which comprises a front clamping section for accomodating an arthoscope. The clamping section includes two semicircular arms which are selectively actuated by a push button. Each arm is biased by a spring which forces the arms to contact and grasp the front end of an arthoscope. Coupled to the other side of the clamp is a focusing section which includes a movable lens. The movable lens is contained within a cylinder and is coupled to an outer cylinder which is slideably positioned with respect to the inner cylinder to enable the lens to move to thereby provide a focusing action. The focusing section is coupled to the input of a television camera. The user can then focus the image from the arthoscope as coupled to the clamping section by means of the focusing section to thereby provide a well defined television signal for many different types of television cameras.
