A Device to Measure Tensile Forces in the Deep Fascia of the Human Abdominal Wall

In order to decrease the incidence of the development of ventral hernias along incision sites after midline abdominal laparotomies, it is critical that a relationship be established between tensile forces applied along the deep fascia and safety of closure. To quantify the tensile forces in the deep fascia, a pair of hemostats with articulating arms and beds and specially designed micro-hooks for attachment, were equipped with two strain gauges. The device was then successfully tested on swine cadavers at the University of Massachusetts Memorial Medical School. It is expected that future testing of the device will result in data that will ultimately allow doctors to select the optimal method for patient care.
