This device is made of two brass rods and two or more (depending on the length of the ladder) cross wires or steps of the ladder. The entire device is nickeled. The rods, or uprights, of the ladder are from 2 to 12 inches long and three-eighths inch in diameter. The steps, or cross bars, are 2½ inches long, and slightly curved.The device does away with the heavy chromic catgut sutures usually placed in the anterior sheath of the rectus, and incidently with a lot of postoperative wound infections; it absolutely prevents cutting of the skin by the tension sutures; it compresses the tissues of the abdominal wall and thus does away with dead space.
The device is placed on the part to be incised, and with the back of the blade of the scalpel two parallel marks are made on the skin just lateral to the uprights
