A PERITONEUM KNIFE.  JOHN R. COOK, M.D.FAIRMONT, W. VA.The accompanying illustrations show a new instrument, a peritoneal knife, which I have found a very convenient device for quickly enlarging the peritoneal opening after making the opening in the usual way. The beak of the knife slides just under the peritoneum, hugging the same closely, and in this way all danger of wounding the intestines is eliminated.I also find it very convenient in enlarging the abdominal ring in operations for the reduction of hernia. As will be seen, the blade is long and will divide all tissues, if necessary, from within outward.
