Hut under certain circumstancescraniotomy upon a living infant is a justifiable operation, andone not to be unreservedly condemned. 768 OBS TE TRIG OPERA T/OA S. The Instruments for the Operation—Embryotomy is the oldest operation of obstetrics and the instruments for performingit would make an interesting historical collection. The sharphook or crotchet in its numerous forms had a place in the obstet-ricians armamentarium for many centuries. At the present daythe operator may need for craniotomy a perforator, a head seizer. Fig. 573.—A, Sharp hook or crotchet; B, Baudelocques cephalotribe. or cranioclast, and a head crusher in its various forms of cephalo-tribe, basiotribe, r basilyst. Perforators.— The best perforator is blots. Smellies perfora-tor or Hodges scissors answer the purpose well enough, and inthe absence of an instrument specially devised lor the purpose,an_\ long, sharp-pointed scissors serves admirably Head Seizers or Cranioclasts.— This instrument was inventedby Sir James Y. Simpson. It has been much improved by Carl EMBRYOTOMY. 769
