LIGAMENT LAXITY MEASURING SYSTEM AND METHOD FOR MEASURING LIGMENT LAXITY

摘要

A ligament laxity measuring system for measuring ligament laxity between a first limb and a second limb connected to each other includes a force module, an angle sensing module and a data processing module. The force module disposed on the first limb is adapted to provide an external force to make the first limb pivot or twist with respect to the second limb, thereby generating a pivoting (varus/valgus) value and a twisting (rotational) value. The force module generates a force signal based on the external force. Opposite two segments of the angle sensing module are disposed on the first limb and the second limb respectively. The angle sensing module is used for sensing the pivoting value and the twisting value of the first limb and generating an angle signal. The data processing module is connected to the force sensor of the force module and the angle sensing module.
