One of the many difficult problems the bronchoscopist encounters in his work is the extraction of the open, "point up" safety-pin in the child's esophagus or trachea. With all due respect to the instruments already devised for that purpose, I believe I have demonstrated successfully at Dr. Forbes Bronchoscopic Clinic at the Post-Graduate Hospital, New York, to the satisfaction of Dr. Forbes and his staff, the ease with which this one difficult problem can be solved by the use of the instrument here presented.
When the ordinary straight tube is used, and the Mosher-Jackson safety-pin closer is passed through this, the loop is entirely outside the line of sight when an attempt is made to bring it into direct line with the spring coil of the pin; hence, when the prong is also passed through the tube, in order to push the pin through the loop, it becomes almost impossible
