Problems solved by technology

MRI and CT examinations can make a corresponding definite diagnosis, but MRI and CT are expensive and difficult for the injured to accept
However, conventional ordinary X-ray examinations often cannot meet the ideal diagnostic requirements. It is necessary to artificially stress all parts of the knee joint. Only by taking X-rays to check whether the knee joint space is widened can the diagnosis be made.
However, there is currently no objective standard for the selection of the stress of the knee joint. If the stress is too small, it may be misdiagnosed. If the stress is too large, it will cause damage to the injured.
Therefore, due to the above-mentioned various reasons, the diagnosis of the knee joint ligament injury of the patient is very easy to cause missed diagnosis, which causes a lot of inconvenience to the work and life of the patient after the injury.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a knee joint ligament stress tester, which belongs to the technical field of orthopedic surgery. Background technique [0002] As we all know, the knee ligament is an important structure to ensure the normal movement function of the knee joint. Knee ligament injury is a common and frequently-occurring disease. If not treated properly, it can lead to joint instability and affect joint function. At present, there are various deficiencies in the examination and diagnosis of knee ligaments. MRI and CT examinations can make a corresponding definite diagnosis, but MRI and CT are expensive and difficult for the injured to accept. However, routine ordinary X-ray examinations often cannot meet the ideal diagnostic requirements. It is necessary to artificially stress all parts of the knee joint. Only by taking X-rays to check whether the knee joint space is widened can the diagnosis be made....
