A HANDY FORM OF HOT SNARE FOR TONSILLOTOMY. [PDF]

JAMA: The Journal of the American Medical Association, 1896
It is acknowledged by many throat surgeons that the galvano-cautery snare is the best instrument for the removal of tonsils, because its acts very efficiently and prevents bleeding. Any one who has used either the hot or the cold snare for tonsillotomy has been able to observe that the wire loop slipped over the tonsil, after the latter has been pulled
