Abstract

Dr. Cope's comments are a welcome supplement to our report on pleural biopsy. Space limitations precluded considerations of the physical characteristics of the biopsy needle, and acknowledgement of Dr. Cope's pioneering work with this device. We have had some difficulty due to backward bending of the hook and because of catching of the hook on the cannula. We agree that such difficulties are always ascribable to errors of technique. Such complications do not occur when the procedure is performed properly. It is true, however, that the sturdiness of the instrument has varied depending on the manner of manufacture. We are pleased to learn that henceforth this instrument will be stronger than in the past and thus no longer subject to the difficulties we have encountered.
