1A1-D03 Development of Evaluation Simulator for Clinical Material in the Finger Joint Ligament Repair

Abstract

In performing the finger joint ligament repair, became possible method using anchor. However, cases where the anchor loses have been reported. The purpose of this study was to evaluate about withdraw of anchor under simple tension and cyclic loading conditions. This experiment were performed using an evaluation simulator for clinical material we developed, and target was the anchor of the JuggerKnot. In the simple tensile test, the materials were pulled in 0.1mm/sec until rupture. In the cyclic loading test, the materials were pulled 200 times in 0.5Hz between from 10N of 30N, subsequently a simple tensile test was performed. It was found from the result that the strength of the anchor was improved by given repeated moderate load.
