| | Method for treating hemorrhoids - Patent 4621635 |
 | | A method of treating external hemorrhoids comprises the preliminary and optional step of rubber band ligation of any associated internal hemorrhoidal tissue, followed by a laser beam-created incision around the perimeter of the base of the external portion. |
 | | In the rubber band ligation technique, a specially designed proctoscope functions as the drum of a ligator and carries a rubber band around its tip. |
 | | As is well known, the banding technique, to be described below, is too painful for use outside the pectinate line, but is appropriate for use internally of that line, where the autonomic nervous system does not carry the sensation of pain. |
