The Parker-Kerr Anastomosis/Intestinal Clamp, Curved (255mm / 10" overall length, with an 80mm jaw), is a large, highly specialized surgical instrument primarily used in general and visceral abdominal surgery. Its core purpose is to securely compress and close the stump of hollow organs—such as the bowel or stomach during a colon resection—to prevent the leakage of internal contents while the surgeon applies sutures or staples.
