Anterior cruciate ligament biomechanical characteristic measuring device

Abstract

The invention belongs to the technical field of biomechanical characteristic measuring devices, and discloses an anterior cruciate ligament biomechanical characteristic measuring device. The device comprises a fixing assembly, a rotating assembly, a tension measuring assembly, a torsion measuring assembly, a moving assembly and a bottom plate, wherein the fixing assembly is used for fixing one end of an anterior cruciate ligament, the rotating assembly is used for realizing the rotation of the fixing assembly, the tension measuring assembly comprises a first driving part and a tension measuring part, and the first driving part is used for driving the movement of the tension measuring part. The device has the advantages of simple structure and convenient use, can perform tension measurement and torsion measurement, and the two measurements are carried out separately without mutual interference; secondly, by arranging the rotating assembly, the output end of a second motor is used for driving a supporting block at the top end of a stand column to rotate, so that the rotation of the fixing assembly can be realized, the direction of the fixing assembly can be quickly adjusted when different measurements are carried out, and the quick fixation of the ligament to be measured is facilitated.

Description

technical field [0001] The invention belongs to the technical field of biomechanical characteristic measuring devices, and in particular relates to a biomechanical characteristic measuring device of anterior cruciate ligament. Background technique [0002] The anterior cruciate ligament starts from the front medial side of the intercondylar eminence of the tibia, heals with the front horn of the lateral meniscus, obliquely goes posteriorly and superiorly laterally, and its fibers attach to the medial side of the lateral femoral condyle in a fan shape. The anterior cruciate ligament is important for maintaining the stability of the knee joint The structure has important physiological functions and significance. The anterior cruciate ligament is composed of numerous fibers and is divided into the anterior inner bundle and the posterior outer bundle. The fibers of the anterior inner bundle have a long journey and start from the static and stable structure before the starting poi...

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for measuring the biomechanical properties of the anterior cruciate ligament to solve the problems that the traditional biomechanical property measuring device proposed in the above-mentioned background technology is complex in structure and difficult to measure the biomechanical properties of the ligament. The flexibility of the device is poor, and it is difficult to adjust the measurement part according to the measurement needs
