ABSTRACT

This device consists in a two vision telescopic attachment for the Jackson type of bronchoscope and esophagoscope. The direct telescopic view is obtained by the operator by attaching the device to the proximal end of the bronchoscope or esophagoscope after the usual introduction of the endoscope. An individual focusing arrangement for the operator and the observer is provided.

A is the operator's eyepiece; B, the observer's eyepiece; C, the prism, and D, the bronchoscope.

There is no magnification, distortion or inversion of the image. The operator has a direct view of the field, while the observer's view is through a prism. A collar on the attaching mechanism permits the observing telescope to be turned to either the right or the left of the operator. In teaching and demonstrating, the value of this attachment is obvious.

Mr. Reinhold Wappler, of the American Cystoscope Makers, Inc., made this instrument for me.
