The closure of the abdominal wall after making a laparotomy is a major challenge for
surgeons, since a significant percentage of closures fail and incisional hernias rise. The suture has
to withstand the forces required to close the incision, while not hindering the adequate wound
healing progression. Currently, there is no surgical measuring device that could be used to determine
the required closing forces, which can be very different depending on the patient. This paper
presents a dynamometer to measure the tension forces to be applied while closing a surgical incision,
and it simultaneously measures the distance between wound edges. It is a compass-like instrument.
A mechanism between the two legs incorporates a load cell, whose signal is read by an electronic
device that computes the values of the tension forces between wound edges. An angular position
sensor at the pin joint between legs provides the distance between both sides of the incision.
Measuring capabilities of the instrument prototype were verified at the laboratory. Thereafter,
its functionality was demonstrated in experimental surgery tests. Therefore, the instrument could be
very useful in clinical applications, assisting personalized surgical techniques.
