Excerpt from The Journal of Cutaneous and Genito-Urinary Diseases, Vol. 20: June, 1902
About six months ago, the writer devised a special instrument for the application of the cautery through a perineal opening (presented to association). It consists. As you will observe, of ... a straight tube with an oblique opening at its distal end, somewhat in the form of an old-fashioned rectal speculum of this pattern. The tube is forty two millimeters in circumference and six and one-half inches in length without the obturator. It has an auxiliary tube carrying a small in candescent lamp of low heating power, which is exposed through a small window near the distal end and on the longer side of the tube. On the short side of the distal end of the tube, and almost directly opposite the lamp, a groove is cut in the side of the tube for the in sertion of the cautery. The groove is intended to give greater rigidity to the knife and greater certainty in the direction and length of the incision. The forms of the cautery thus far used are here presented and consist in three modifications of the cautery knives, used for nose and throat and other galvano-cautery purposes. It will be observed that one is of greater length than the others and has an oblique angle.
