Abstract
A suitable tension is critical to good prognoses of surgical repair of injured tendons or ligaments. The existing transducers have limiting roles in measuring the repair tension of intact tendons or ligaments. This study fabricated a sensor to assist surgeons in measuring tension during repair surgery. A peg-type force transducer made from stainless steel served the advantages of easy application and sterilizability. The electrical signals were stabilized by a bridge circuit coupled with two strain gauges. The performances of the system, which were tested by thin and thick silicon tubes, were linear to the applied forces. The results suggest that this system is reliable for force measurement and is beneficial for optimizing the tension of tendons or ligaments during repair surgeries. © 2012 Taylor and Francis Group, LLC.
