An automatic cartridge stapl

Abstract An automatic cartridge stapler holding fifteen individual staples is described. Its use in the laboratory on blood vessel anastomoses and repairs, small and large bowel anastomoses, and bronchial stump closures is described and the advantages of this instrument over previous stapling devices are presented. The results of this study raise the possibility that the stapling method of anastomosis or closure may have certain advantages over those methods using standard sutures.

Alterations in Growth of Strain L Cells Exposed to Smoke Gases

Summary Under the conditions of this study it appears that there is a “toxic” effect of smoke gases on strain L cells in culture. This results both in morphological changes in the cells and in alterations in growth curves as indicated by the reduction of cell populations. The smoke from the combustion of either cigarette paper or onion skin paper appears to be more “toxic” than that from the combustion of a cigarette or cigarette tobacco alone. The effect of cigarette or other smoke gases may result in part, at least, from the particulate matter present in smoke gases.

Unusual presacrococcygeal cystic tumors

Abstract Two cases of unusual presacrococcygeal cyst tumors have been presented. The surgical problems involved are discussed, and the approach to the removal of such cystic tumors is reviewed.

Renal vascular anastomosis by the American vascular stapler

Summary A new American vascular stapler was used to reanastomose renal arteries and veins in dogs. The anastomoses were done rapidly and essentially without difficulty. Follow-up studies which included pyelography, arteriography and, in some dogs, pathologic examination of tissues, demonstrated the feasibility of stapling as a method for anastomosis of these vessels.

A hemostatic clip

Abstract We have used a new hemostatic clip extensively in our laboratory and to some extent clinically, with complete satisfaction. The design of the applicator prevents the clip from dropping out of the jaws during ordinary usage, and a locking lever enables the scrub nurse to load the applicators both easily and rapidly. We believe that this hemostatic clip will prove of great help to the surgeon in securing hemostasis in selected relatively inaccessible areas.
