Knee joint collateral ligament injury detection device

Abstract

The invention discloses a knee joint collateral ligament injury detection device. The knee joint collateral ligament injury detection device comprises a tibia gyroscope assembly and an upper computer;the tibia gyroscope assembly is attached to a tibia nodule, and the tibia gyroscope assembly is in communication connection with the upper computer; the tibia gyroscope assembly is used for detectingthe inward and outward turning angle data of the tibia relative to the femur and transmitting the inward and outward turning angle data to the upper computer; and the upper computer is used for analyzing the inward and outward turning angles of the tibia in the knee joint lateral stress test according to the collected inward and outward turning angle data. According to the device, the injury indexing of the collateral ligament is evaluated by measuring the inward and outward turning angles of the knee joint, so that the problem of injury indexing of the collateral ligament clinically is solved.

Description

technical field [0001] The invention relates to the technical field of damage detection, in particular to a device for detecting damage to the collateral ligament of the knee joint. Background technique [0002] The medial and lateral collateral ligaments of the knee joint are one of the common ligament injuries in the knee, and they are also common ligament injuries that are easily missed and misdiagnosed. After the knee collateral ligament injury, due to misdiagnosis and missed diagnosis without proper treatment, the injured collateral ligament is not easy to heal, resulting in loss of ligament function, which easily leads to a decrease in the stability of the knee joint, followed by knee joint instability, other knee ligament injuries, Complications such as osteoarthritis, leading to pain and joint dysfunction. [0003] The clinical diagnosis of knee joint medial and lateral collateral ligament injuries mainly includes knee joint magnetic resonance (MRI) examination, kne...

AI Technical Summary

Problems solved by technology

After the knee collateral ligament is injured, due to misdiagnosis and missed diagnosis, appropriate treatment is not taken, and the injured collateral ligament is not easy to heal, resulting in loss of ligament function, which easily leads to a decrease in the stability of the knee joint, followed by knee joint instability, other knee ligament injuries, Complications such as osteoarthritis, which causes pain and joint dysfunction

[0003] The clinical diagnosis of knee joint medial and lateral collateral ligament injuries mainly includes knee joint magnetic resonance (MRI) examination, knee joint stress X-ray film and knee joint lateral stress test. Knee joint MRI can clearly identify lateral collateral ligament injury, but cannot To classify the degree of injury, knee joint stress X-ray film can diagnose collateral ligament injury through the obvious widening of the inner and outer space of the knee joint, but the examiner needs to perform the knee joint lateral stress test under the condition of X-ray irradiation, which is inconvenient to operate and has X-ray line radiation
